Abstract (en)

A method for shaping a set of capillaries of collector (20) of heat exchanger (10) of heat machine (5) with the set (40) of capillaries distributing a cooling medium to sections of heat exchanger (10), according to which each capillary (41, 42, 43, 44, 45) is connected at one end to its associated distribution manifold (31, 32, 33), and at another end to its associated inflow connector (21, 22, 23, 24, 25) of the section of the heat exchanger (10).The capillary (45) is shaped of a straight section (71) and upper inflow bends (72) and lower inflow bends (73) whereas a capillary (44) situated near the distribution manifold (31, 32, 33) is given a shape of a helix that has at least one whole coil (75), the upper inflow bend (72) and the lower inflow bend (73) and to the capillary (44) adjacent the capillary (45) with the straight section (71) is added one more coil (75) and whereas to each next capillary (43, 42), going towards the distribution manifold (31, 32, 33), is added one coil more than has previous capillary, whereby a size of the capillary with coils determined by a diameter (d) of the capillary tube, a number of coils, an outer diameter (D) of coils and a spiral lead (H) of the capillary helix are selected experimentally in such a way that the flow resistance of the cooling medium of capillary tubes does of capillaries (41, 42, 43, 44, 45) one of set (40) not differ each other by more than 30%, regardless of location of the inflow connectors (21, 22, 23, 24, 25) in respect to the distribution (31, 32, 33).
