Description

[0001] The present invention refers to a radiator with a radiating plate and to a procedure for circulating a fluid inside of it.

[0002] In particular, hereafter reference shall be made to radiators consisting of a single plate at the angles of which four fittings are usually connected through which a heating fluid is introduced or discharged into/from the radiator.

[0003] Conventional radiators of the type indicated, however, have numerous drawbacks mainly due to the fact that, since the supply and discharge fittings are arranged in correspondence with the corners of the plate, the installer must position the connection fittings of the house-heating unit in different positions according to the type of radiator intended to be installed and its size.

[0004] Moreover, such types of radiator are not very resistant to stress with all the consequences which can come from this, for example in transportation.

[0005] The technical task proposed of the present invention is, therefore, that of eliminating the aforementioned technical drawbacks of the prior art, realising a radiator with a radiating plate and of indicating a procedure for heating it which allows the fittings for connection to the house-heating unit to be installed irrespective of the type and size of the radiator intended to be installed.

[0006] In this technical task a purpose of the invention is that of realising a radiator which is also particularly rigid and strong.

[0007] The last but not least purpose of the invention is that of realising a radiator which is transportable without drawbacks of any sort.

[0008] The technical task, as well as these and other purposes, according to the present invention, are achieved by realising a radiator with a radiating plate, where the plate has at least one upper collector and at least one lower collector connected to each other through a plurality of channels, characterised in that said plate is divided into two parts defining at least one first and one second portion hydraulically connected through hydraulic connection means, said first portion having a supply fitting and said second portion having a discharge fitting for a heating fluid.

[0009] The invention also refers to a procedure for circulating a fluid inside a radiator with radiating plates, characterised in that a heating fluid is entered into a substantially central zone of said plate divided into a first and second portion, it is initially made to circulate just in said first portion and then is transferred from said first portion to said second portion and is discharged from said second portion from a substantially central zone.

[0010] Other characteristics of the present invention are defined, moreover, in the subsequent claims.

[0011] Further characteristics and advantages of the invention shall become clearer from the description of a preferred but not exclusive embodiment of the radiator with radiating plate and of the procedure for circulating a fluid inside of it according to the finding, where the radiator is illustrated for indicating and not limiting purposes in the attached drawings, in which:

• figure 1 shows a partially exploded schematic perspective view of a first embodiment of the radiator;
• figure 2 shows a partially exploded schematic perspective view of a second embodiment of the radiator;
• figure 3 shows a partially exploded schematic perspective view of a third embodiment of the radiator;
• figure 3a shows a schematic perspective view of two different embodiments of radiator pipes according to the finding; and
• figure 4 shows a cross section of a special fitting of the radiator according to the finding.

[0012] With reference to the quoted figures, a radiator with a radiating plate is shown, wholly indicated with reference numeral 1.

[0013] The radiator 1 comprises a plate 2 which has two upper collectors 3 and two lower collectors 4 connected to each other by a plurality of channels 5 and hydraulically separated along a line 50 (for example welded, bent, realised through a partition, etc.) which divides the plate 2 into a first and second portion.

[0014] The plate 2 has, in particular, the first portion 6 and the second portion 7 connected through hydraulic connection means 8; the first portion 6 of the plate 2 has a supply fitting 9 for a heating fluid and the second portion has a discharge fitting 10 for the heating fluid.

[0015] Advantageously, the connection means 8 are outside the plate 2.

[0016] Preferably, the supply and discharge fittings 9, 10 for the heating fluid are connected to the plate 2 at a central and lower position thereof.

[0017] The heating fluid cannot pass from the first portion 6 to the second portion 7 or vice-versa through the upper or lower collectors 3, 4, or through one of the channels 5, but just through the connection means 8 outside of the plate 2.

[0018] The plate 2 has four fittings positioned in correspondence with the upper and lower corners and, in particular, has two T-shaped fittings 11, 12 in correspondence with the upper corners and two L-shaped fittings positioned in correspondence with the lower corners.

[0019] The connection means 8 comprise a pipe connected to each of the two portions of the plate.

[0020] In a first embodiment, shown in figure 1, the pipe 8 has the first and second ends connected at 13, 14 to the fittings 11, 12 and is defined by a grid 15, for example made from folded sheet metal.

[0021] In a second example, shown in figure 2, the pipe 8 has the first end connected at 13 to the fitting 11 and the second end connected in correspondence with a central portion of the plate 2 substantially aligned with the discharge fitting 10.

[0022] In figure 3 a further embodiment of the radiator is shown, in which the pipe 8 has a rectangular, rounded or squared section.

[0023] In this way the pipe 8 occupies a very small space and can be hidden, for example, in the grid.

[0024] Preferably, the pipe 8 is substantially positioned horizontally and in correspondence with the upper fittings of the plate.

[0025] In a preferred embodiment, at least one of said fittings which connect to the pipe 8 comprises a special fitting 16.

[0026] In particular, in figure 4 a section of the special fitting 16 is shown.

[0027] The special fitting 16 comprises a tubular body 17 inside of which two L-shaped protuberances 18 extend from two opposite portions of the body 17, which define a through-port 19

[0028] A shutter 20 of a modulating valve 21, connected to a seat of the body 17 and capable of being actuated automatically by a thermostatic head or else by an operator to close the port 19 manually, can be associated with said port 19.

[0029] The radiator allows the tubes of the home heating units to be laid in a very simple manner since the position of the supply and discharge fittings is always known irrespective of the type and size of the radiator.

[0030] The procedure for circulating a fluid inside the radiator with a radiating plate according to the invention is substantially the following.

[0031] The heating fluid enters from the supply fitting 9 into the plate and crosses the first portion 6 (as indicated by the arrows), it moves in correspondence with the fitting 13 and passes into the pipe 8.

[0032] From the pipe 8 it passes into the second portion 7 of the plate 2, it crosses it and comes out from the second portion 7 of the plate through the discharge fitting 10.

[0033] The procedure for circulating the fluid also consists of the fact that the heating fluid is entered into a central zone (through the fitting 9) of the plate 2 of the radiator, it flows towards a first side portion thereof (towards the fitting 11), it passes into a second side portion (through the fitting 12) of the radiator through a pipe outside of the plate and again flows towards the centre of the radiator (fitting 10) from where it is discharged.

[0034] In the first portion the fluid circulates from the bottom to the top of the plate whereas in the second it circulates from the top to the bottom.

[0035] In practice, it has been noted how the radiator with a radiating plate and the procedure for circulating a fluid inside it according to the invention are particularly advantageous because the pipe occupies a very small space and can even be hidden by the grid.

[0036] Moreover, the pipe makes the radiator particularly rigid and strong, reducing its problems of transportation and fitting.

[0037] The radiator with a radiating plate and the procedure for circulating a fluid inside of it thus conceived are susceptible to numerous modifications and variants, all of which are covered by the inventive concept; moreover, all of the details can be replaced by technically equivalent elements.

[0038] In practice, the materials used, as well as the sizes, can be whatever according to the requirements and the state of the art.
