  • Patent number: 12111122
    Abstract: 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.
