摘要： A heat exchanger includes a collecting pipe, a number of heat exchange tubes and a distributor. The collecting pipe has a first cavity and a first inner peripheral wall. The heat exchange tube has a second cavity. The distributor is accommodated in the first cavity. The distributor has a main cavity and a flow channel. The distributor includes a second inner peripheral wall forming the main cavity and a first outer peripheral wall. An axis of the first outer circle is not coaxial with an axis of the second outer circle, so that the flow channel of the distributor is relatively tortuous. It is beneficial to improve the distribution effect of a fluid. Besides, since the flow channel is formed inside the distributor, it is also beneficial to reduce the manufacturing difficulty of the distributor. A method for making the heat exchanger is also disclosed.

摘要： The present disclosure discloses a heat exchanger including a group of collecting pipes and a number of heat exchange assemblies. Each heat exchange assembly includes a fin plate and at least one heat exchange tube. The heat exchange assembly includes a main heat exchange area. The heat exchange tube is connected with the fin plate. The heat exchange tube at least partially protrudes from at least one side of the fin plate. In addition, in the main heat exchange area corresponding to two adjacent heat exchange assemblies, at least two adjacent heat exchange tubes are staggered along an array direction of the heat exchange assemblies. The two heat exchange tubes respectively belong to the two adjacent heat exchange assemblies. The present disclosure is beneficial to improve the performance of the heat exchanger.
