Problems solved by technology
The heat exchanger includes headers and heat exchange tubes. When the refrigerant flows into the heat exchanger, it is distributed into the heat exchange tubes through the headers. However, when the refrigerant is a gas-liquid two-phase in the related heat exchanger, its distribution uniformity needs to be determined. improve

The heat exchanger disclosed in the present application includes a header, a plurality of heat exchange tubes and fins, the plurality of heat exchange tubes are arranged approximately in parallel, distributed along the axial direction of the header and inserted into the header, A baffle is arranged in the header, and the baffle divides the inner cavity of the header into a first sub-chamber and a second sub-chamber, one end of the heat exchange tube is connected to the first sub-chamber When the refrigerant enters the header, it first flows into the second sub-chamber, and after interacting with the heat exchange tube inserted into the second sub-chamber, it forms a severe turbulent flow effect, and then flows into the first sub-chamber through the through hole set in the partition plate. cavity, and then flow into the heat exchange tubes, the heat exchanger of the present application can relatively improve the uniformity of two-phase refrigerant distribution.
Description
technical field [0001] The present application relates to the field of heat exchange, in particular, to a heat exchanger and a heat exchange system. Background technique [0002] Over the past few decades, the heat exchange industry has developed rapidly, and heat exchangers, as one of the main components of air conditioners, also need to be improved and optimized in design. The heat exchanger includes headers and heat exchange tubes. When the refrigerant flows into the heat exchanger, it is distributed into the heat exchange tubes through the headers. However, when the refrigerant is a gas-liquid two-phase in the related heat exchanger, its distribution uniformity needs to be determined. improve. Contents of the invention [0003] According to one aspect of the present application, a heat exchanger is provided, the heat exchanger includes a header, a heat exchange tube, and a separator, the header includes a first header, and the first header It has a pipe wall and a fi...
