Abstract (en)
A heat exchanger (100a) includes a plurality of tubes (4), an entrance header (1) for distributing a refrigerant to the tubes (4), and an exit header (2) for collecting the refrigerant from the tubes (4). The entrance header (1) includes a circulating conduit (10) capable of circulating at least part of the refrigerant that has flowed into the entrance header (1), and the plurality of tubes (4) are fluidly connected to the outward channel (10a) of the circulating conduit (10). The entrance header (1) also includes an ejector 11 that uses the refrigerant flowing into the entrance header to draw and mix at least part of the refrigerant that has flowed into the entrance header and spray out the mixed refrigerant. The entrance header (1) can supply refrigerant more uniformly to the tubes (4) connected to the circulating conduit (10).
