Title: HEAT EXCHANGER CONSTITUTING A REFRIGERANT CIRCUIT
Abstract:
The invention relates to a heat exchanger (5) comprising a collector box and a return means (9) between which a first layer (11) of first tubes (10a) and a second layer (12) of second tubes (10b) are inserted. The first tubes (10a) comprise a first end (101) in fluid communication with the return means (9) and a second end (102) in fluid communication with the collector box (8). The second tubes (10b) comprise a third end (103) in fluid communication with the return means (9) and a fourth end (104) in fluid communication with the collector box (8). The collector box accommodates at least one device for homogenising the distribution of a refrigerant along the collector box (8). The return means (9) comprises at least one partition (23a) which subdivides the return means (9) into at least two compartments (24), each compartment (24) being provided with at least one end (101, 103) of a tube (10a, 10b).
