摘要： There is provided a heat exchanger including: a heat exchange section in which a plurality of flat tubes are arranged substantially in parallel in a minor axis direction at first intervals and in which fins are disposed between the flat tubes; and a header to which at least some flat tubes out of the plurality of flat tubes are connected, in a state where the at least some flat tubes are bent in the minor axis direction outside the heat exchange section and end parts of the at least some flat tubes are arranged substantially in parallel at second intervals that are narrower than in the heat exchange section, so that the minor axis direction and a central axis direction of the header are the same direction. With this heat exchanger, it is possible to distribute fluid to the individual flat tubes with more equal conditions so that the heat exchange efficiency can be increased.

摘要： There is provided a method of manufacturing a heat exchanger, including a first step of mounting an end part of flat tube to a header, assembling the flat tube and fins, and sealing a part where the header and the end part is attached, and a second step of increasing an internal pressure of the flat tube to expand other part of flat tubes aside from the end parts with respect to the end part of the tube in order to make the fins and the other part of the flat tube in contact each other. According to this method of manufacturing, in the second step, the other part of the flat tube that passes through the fins is expanded, so that it is possible to mechanically join the flat tube and the fins, and a plate fin-type heat exchanger with high strength and heat exchange efficiency can be easily provided.

摘要： 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).
