A heat exchanger includes a main body portion and a cover. The main body portion includes a heat exchange core, a collecting pipe portion and a first mounting shell. The collecting pipe portion includes a first collecting pipe portion and a second collecting pipe portion. Both the first collecting pipe portion and the second collecting pipe portion are provided with mounting end plates. Two ends of the first mounting shell are hermetically connected to the mounting end plates by brazing. The first mounting shell encloses part of the heat exchange core in a circumferential direction. Two ends of the cover are hermetically connected to the mounting end plates by bonding. The cover and the first mounting shell are arranged in an enclosing manner in the circumferential direction. The heat exchanger improves stability and reliability. A manufacture method of the heat exchanger is also disclosed.

Heat exchanger and manufacturing method thereof

A heat exchanger includes a first collecting pipe, a number of heat exchange tubes and a partition plate. The heat exchange tubes are inserted into the first collecting pipe. By means of the partition plate, a first inner cavity of the first collecting pipe is divided into a first sub-cavity and a second sub-cavity. One end of each heat exchange tube is in communication with the first sub-cavity. In the process of a refrigerant entering the first collecting pipe, the refrigerant flows into the second sub-cavity firstly, and forms a severe turbulence effect after interacting with the heat exchange tubes inserted into the second sub-cavity. Then, the refrigerant flows into the first sub-cavity through holes provided in the partition plate, and then flows into the heat exchange tubes. As a result, the uniformity of the two-phase refrigerant distribution can be relatively improved.
