[0029] As illustrated in Fig. 3 to 5, a module 30 comprises a substrate 32, a cooling unit 33, a supply connection tube (connection tube) 36 and a discharge connection tube (connection tube) 37.

[0030] The substrate 32 is in the form of a rectangular plate. In the state in which the module 30 is housed in the enclosure 21, the substrate 32 is arranged so that a long edge S11 is aligned with the front-rear direction Df and the short edge S12 is aligned with the vertical direction Dv. The substrate 32 is connected, so as to be able to be inserted and removed, to a module connector 23 provided on the base substrate 26.

[0031] The substrate 32 has a heat-generating component 34 such as a CPU (Central Processing Unit). The heat-generating component 34 is mounted on one surface 32f of the substrate 32. The heat-generating component 34 is not limited to being a CPU, and may be another electronic component.

[0032] The cooling unit 33 is provided on the substrate 32. The cooling unit 33 is provided so as to be stacked on the heat-generating component 34. The cooling unit 33 cools the heat-generating component 34. The cooling unit 33 has a prescribed thickness in the direction orthogonal to the one surface 32f of the substrate 32. The cooling unit 33 has a recess 33s on the surface facing the heat-generating component 34. The recess 33s faces at least part of the surface of the heat-generating component 34.

[0033] The supply connection tube 36 has one end 36a connected to the cooling unit 33. The supply connection tube 36 extends outside the substrate 32. The supply connection tube 36 extends from the substrate 32 through an opening 25 formed in the rear plate 21r of the enclosure 21, and to the rear of the enclosure 21. The supply connection tube 36 has flexibility. The supply connection tube 36 has a connection elbow 36c on the other end extending to the rear of the enclosure 21.

[0034] The discharge connection tube 37 has one end 37a connected to the cooling unit 33. The discharge connection tube 37 extends to the outside of the substrate 32. The discharge connection tube 37 extends from the substrate 32 through an opening 25 formed in the rear plate 21r of the enclosure 21, and to the rear of the enclosure 21. The discharge connection tube 37 has flexibility. The discharge connection tube 37 has a connection elbow 37c on the other end extending to the rear of the enclosure 21.

[0035] Such a module 30 is connected to each of the plurality of module connectors 23 provided in the width direction (first direction) Dw inside the enclosure 21. As a result thereof, a plurality of modules 30 arranged along the width direction Dw are provided inside the enclosure 21.

[0036] As illustrated in Fig. 2 and Fig. 4, inside the rack 110, supply branching tubes (branching tubes) 41 and discharge branching tubes (branching tubes) 42 are provided. A supply branching tube 41 and a discharge branching tube 42 are provided outside the enclosure 21 of each server 20. The supply branching tube 41 and the discharge branching tube 42 are provided to the rear, in the front-rear direction Df, of each server 20. In other words, the supply branching tube 41 and the discharge branching tube 42 are provided on one side (to the rear) in the sliding direction (front-rear direction Df) of the enclosure 21. The supply branching tube 41 and the discharge branching tube 42 are each supported on the enclosure 21 by a supporting member, which is not illustrated.

[0037] The supply branching tube 41 and the discharge branching tube 42 each extend in the width direction Dw of the enclosure 21.

[0038] On the supply branching tube 41, a plurality of connection portions, to which connection elbows 36c of supply connection tubes 36 are connected, are provided along the axial direction (width direction Dw) of the supply branching tube 41. The connection elbows 36c of the supply connection tubes 36 are detachably connected to the supply branching tube 41. As a result thereof, the supply branching tube 41 and the cooling units 33 of the modules 30 are respectively connected by supply connection tubes 36.

[0039] On the discharge branching tube 42, a plurality of connection portions, to which connection elbows 37c of discharge connection tubes 37 are connected, are provided along the axial direction (width direction Dw) of the discharge branching tube 42. The connection elbows 37c of the discharge connection tubes 37 are detachably connected to the discharge branching tube 42. As a result thereof, the discharge branching tube 42 and the cooling units 33 of the modules 30 are respectively connected by discharge connection tubes 37.

[0040] The supply branching tube 41 and the discharge branching tube 42 are provided so as to leave a gap therebetween. Specifically, the supply branching tube 41 and the discharge branching tube 42 are provided so as to leave a gap in the vertical direction Dv. In other words, the supply branching tube 41 and the discharge branching tube 42 are located at different positions in the vertical direction Dv. The supply branching tube 41 and the discharge branching tube 42 are provided at positions facing the rear plate 21r of the enclosure 21 in the front-rear direction Df.

[0041] Thus, a plurality of supply branching tubes 41 and discharge branching tubes 42 are provided so as to be respectively connected to the plurality of enclosures 21. The supply branching tubes 41 and the discharge branching tubes 42, as mentioned above, are supported on the enclosures 21 by means of support members (not illustrated), and thus can slide, together with the enclosures 21, in the front-rear direction Df inside the rack 110.

[0042] Therefore, when the enclosure 21 of each server 20 is made to slide in the front-rear direction Df inside the rack 110, the modules 30, the supply branching tube 41 and the discharge branching tube 42 slide together with the enclosure 21. In this case, modules 30 connected to the module connectors 23 are housed inside the enclosure 21, and the cooling units 33 are in a state of connection to the supply branching tube 41 and the discharge branching tube 42, by means of supply connection tubes 36 and discharge connection tubes 37, respectively.

[0043] As illustrated in Fig. 2, the supply branching tubes 41 are connected to the supply tube 101. The supply branching tubes 41 are detachably connected to the supply tube 101. The supply tube 101 and the supply branching tubes 41 are connected by means of intermediate connection tubes (second connection tubes) 51 having flexibility. The intermediate connection tubes 51 are detachably connected to the supply tube 101.

[0044] The supply branching tubes 42 are connected to the supply tube 102. The supply branching tubes 42 are detachably connected to the discharge tube 102. The discharge tube 102 and the discharge branching tubes 42 are connected by means of intermediate connection tubes (second connection tubes) 52 having flexibility. The intermediate connection tubes 52 are detachably connected to the discharge tube 102.

[0045] Thus, the plurality of sets of supply branching tubes 41 and discharge branching tubes 42 provided respectively on the servers 20 are respectively detachably connected to a single supply tube 101 and a single discharge tube 102.

[0046] Cooling water is fed, through the supply tube 101, to the supply discharge tube 41 of each server 20. In each server 20, cooling water is fed through the supply branching tubes 41 to the supply connection tubes 36. The supply connection tubes 36 supply cooling water to the recesses 33s in the cooling units 33.

[0047] The discharge connection tubes 37 discharge cooling water from the recesses 33s in the cooling units 33. The cooling water that is discharged through the discharge connection tubes 37 is discharged from the discharge branching tubes 42 and the discharge tube 102 to the outside.

[0048] This server device 100 comprises a rack 110, enclosures 21 provided inside the rack 110, and modules 30 provided inside the enclosures 21. This server device 100 comprises a supply tube 101, a discharge tube 102, supply branching tubes 41, discharge branching tubes 42, supply connection tubes 36 and discharge connection tubes 37. Furthermore, modules 30 are connected to a plurality of module connectors 23 provided inside the enclosures 21, and the enclosures 21 are able to slide in a state in which the cooling units 33 are connected to the supply branching tubes 41 and the discharge branching tubes 42 respectively by means of the supply connection tubes 36 and the discharge connection tubes 37.

[0049] As a result thereof, the enclosures 21 can be pulled out from the rack 110 and maintenance work and the like can be performed on the servers 20 without removing the supply branching tubes 41 and the discharge branching tubes 42 respectively from the supply connection tubes 36 and the discharge connection tubes 37. Additionally, a plurality of module connectors 23 are provided, so a plurality of modules 30 can be connected inside an enclosure 21. Additionally, when an enclosure 21 is in a state of removal from the rack 110, the module connectors 23 are provided inside the enclosure 21, so the modules 30 can be easily attached to and detached from the enclosure 21. Therefore, work such as the replacement of modules 30 inside the enclosure 21 can be easily performed.

[0050] In this server device 100, the supply branching tubes 41 and the discharge branching tubes 42 are respectively detachably connected to the supply tube 101 and the discharge tube 102. The supply branching tubes 41 and the discharge branching tubes 42 are respectively removed from the supply tube 101 and the discharge tube 102. As a result thereof, when a supply branching tube 41, a discharge branching tube 42 and an enclosure 21 are made to slide, the supply branching tube 41 and the discharge branching tube 42 can be moved together with the enclosure 21. As a result thereof, the modules 30 can be easily attached to and detached from the enclosure 21 that has been made to slide.

[0051] In this server device 100, in a configuration in which the modules 30 are able to be attached to and detached from the module connectors 23, the supply connection tubes 36 and the discharge connection tubes 37 are able to be respectively attached to and detached from the supply branching tubes 41 and the discharge branching tubes 42. As a result thereof, the modules 30, the supply connection tubes 36 and the discharge connection tubes 37 can be removed from the enclosures 21 together. Therefore, the modules 30 (and the supply connection tubes 36 and the discharge connection tubes 37) can be easily replaced.

[0052] In this server device 100, supply connection tubes 36 and discharge connection tubes 37 having one end 36a, 37a connected to the modules 30 are arranged in the width direction Dw, which is the direction in which the modules 30 are arrayed. As a result thereof, the connection elbows 36c, 37c on the other ends of the supply connection tubes 36 and the discharge connection tubes 37 can be easily connected, respectively, to the supply branching tubes 41 and the discharge branching tubes 42, which extend in the width direction Dw.

[0053] In this server device 100, the supply branching tubes 41 and the discharge branching tubes 42 are provided outside the enclosures 21. As a result thereof, the work for attaching and detaching the supply connection tubes 36 and the discharge connection tubes 37 of the modules 30 with respect to the supply branching tubes 41 and the discharge branching tubes 42 can be performed outside the enclosures 21, thereby raising the work efficiency.

[0054] In this server device 100, the supply branching tubes 41 and the discharge branching tubes 42 are provided to the rear in the sliding direction of the enclosures 21. As a result thereof, the work for attaching and detaching the supply connection tubes 36 and the discharge connection tubes 37 with respect to the supply branching tubes 41 and the discharge branching tubes 42 can be performed from the rear of the rack 110, thereby raising the work efficiency.

[0055] In this server device 100, a supply branching tube 41 and a discharge branching tube 42 are provided on each of a plurality of enclosures 21. Additionally, the plurality of supply branching tubes 41 and the discharge branching tubes 42 are detachably connected, respectively, to a single supply tube 101 and a single discharge tube 102. As a result thereof, a supply branching tube 41 and a discharge branching tube 42 are provided for each enclosure 21. Therefore, it is possible to arrange the supply connection tubes 36 and the discharge connection tubes 37 in an orderly manner between a plurality of servers 20.

[0056] In this server device 100, the supply tube 101 and the discharge tube 102 are respectively connected to the supply branching tubes 41 and the discharge branching tubes 42 by means of intermediate connection tubes 51, 52 having flexibility.

[0057] As a result thereof, the enclosures 21 can be made to slide forward and rearward to some degree with the supply tube 101 and the discharge tube 102 respectively still connected to the supply branching tubes 41 and the discharge branching tubes 42 by means of the intermediate connection tubes 51, 52. Additionally, the work of attaching and detaching the intermediate connection tubes 51, 52 to the supply tube 101 and the discharge tube 102, and to the supply branching tubes 41 and the discharge branching tubes 42, respectively, can be easily performed.

[0058] In such a server device 100, the supply connection tubes 36 and the discharge connection tubes 37 can be respectively connected to the supply branching tubes 41 and the discharge branching tubes 42 provided outside the enclosures 21 through openings 25 formed in the enclosures 21.

[First modified example of second embodiment]



[0059] In the above-mentioned second embodiment, the supply connection tubes 36 and the discharge connection tubes 37 were arranged to be connected, respectively, to the supply branching tubes 41 and the discharge branching tubes 42 from the front in the front-rear direction Df. For example, the supply connection tubes 36 and the discharge connection tubes 37 were respectively connected to sites located on the front sides, in the front-rear direction Df, of the supply branching tubes 41 and the discharge branching tubes 42. However, there is no limitation thereto.

[0060] Fig. 6 is a perspective view illustrating the structure of a server according to a first modified example of the second embodiment.

[0061] As illustrated in Fig. 6, the supply connection tubes 36 and the discharge connection tubes 37 are respectively connected to the supply branching tube 41 and the discharge branching tube 42 at sites other than sites facing the enclosure 21. For example, the supply connection tubes 36 and the discharge connection tubes 37 are respectively connected to the supply branching tube 41 and the discharge branching tube 42 at sites at locations different from sites facing the enclosure 21. In the present modified example, the connection elbows 36c, 37c of the supply connection tubes 36 and the discharge connection tubes 37 are respectively connected to the supply branching tube 41 and the discharge branching tube 42 from the rear in the front-rear direction Df. For example, the supply connection tubes 36 and the discharge connection tubes 37 are respectively connected at sites positioned on the rear sides, in the front-rear direction Df, of the supply branching tube 41 and the discharge branching tube 42.

[0062] In this server device 100, the work of attaching and detaching the supply connection tubes 36 and the discharge connection tubes 37, respectively, to the supply branching tube 41 and the discharge branching tube 42 can be performed from the rear of the supply branching tube 41 and the discharge branching tube 42. As a result thereof, the work efficiency is raised.

[Second modified example of second embodiment]



[0063] Fig. 7 is a perspective view illustrating the structure of a server according to the second modified example of the second embodiment.

[0064] As illustrated in Fig. 7, a supply branching tube 41 and a discharge branching tube 42 are provided so as to leave a gap therebetween in the vertical direction Dv. The supply branching tube 41 and the discharge branching tube 42 are provided at positions facing the rear plate 21r of the enclosure 21 in the front-rear direction Df.

[0065] The supply connection tubes 36 and the discharge connection tubes 37 extend to the rear of the supply branching tube 41 and the discharge branching tube 42 by passing in between the supply branching tube 41 and the discharge branching tube 42. The supply connection tubes 36 and the discharge connection tubes 37 respectively curve forward at the rear, in the front-rear direction Df, of the supply branching tube 41 and the discharge branching tube 42. The supply connection tubes 36 and the discharge connection tubes 37 are respectively connected to the supply branching tube 41 and the discharge branching tube 42 at sites other than sites facing the enclosure 21. In the present modified example, the connection elbows 36c, 37c of the supply connection tubes 36 and the discharge connection tubes 37 are respectively connected from the rear, in the front-rear direction Df, of the supply branching tube 41 and the discharge branching tube 42.

[0066] In this server device 100, the supply branching tube 41 and the discharge branching tube 42 are provided with a gap therebetween. As a result thereof, the supply connection tubes 36 an the discharge connection tubes 37 can be passed between the supply branching tube 41 and the discharge branching tube 42. Additionally, working space for attaching and detaching the supply connection tubes 36 and the discharge connection tubes 37, respectively, to the supply branching tube 41 and the discharge branching tube 42 can be secured.

[0067] In this server device 100, the supply branching tube 41 and the discharge branching tube 42 are provided so as to leave a gap therebetween in the vertical direction. The supply connection tubes 36 and the discharge connection tubes 37 are arranged to pass between the supply branching tube 41 and the discharge branching tube 42. Thus, the supply connection tubes 36 and the discharge connection tubes 37 can be kept from sagging down by passing the supply connection tubes 36 and the discharge connection tubes 37 between the supply branching tube 41 and the discharge branching tube 42.

[0068] In this server device 100, the supply branching tube 41 and the discharge branching tube 42 are respectively connected with the supply connection tubes 36 and the discharge connection tubes 37 on sides not facing the enclosure 21, in other words, on the rear sides in the front-rear direction Df. As a result thereof, the connection work for connecting the supply connection tubes 36 and the discharge connection tubes 37, respectively, with the supply branching tube 41 and the discharge branching tube 42 can be easily performed from the rear of the supply branching tube 41 and the discharge branching tube 42.

[0069] In the above-mentioned second embodiment and the modified examples thereof, the intermediate connection tubes 51, 52 are respectively detachably connected to the supply tube 101 and the discharge tube 102, but the intermediate connection tubes 51, 52 may be provided with slack. As a result thereof, it is possible to slide the enclosures 21 in the front-rear direction Df while the supply branching tubes 41 and the discharge branching tubes 42 remain connected to the supply tube 101 and the discharge tube 102 by means of the intermediate connection tubes 51, 52.

[0070] Additionally, the supply branching tubes 41 and the discharge branching tubes 42 were connected, respectively, to the supply tube 101 and the discharge tube 102 by means of flexible intermediate connection tubes 51, 52. However, the invention is not limited to such a structure.

[0071] Fig. 8 is a perspective view illustrating the structure of a server device according to another modified example of the second embodiment.
