Embodiment Construction
[0027] The present application relates to a plate heat exchanger (not shown), which includes a number of stacked heat exchange plates 100, and adjacent heat exchange plates 100 form a first flow channel and a second flow channel spaced apart from each other. Wherein the first flow channel is used for the circulation of the brine (such as cooling liquid), and the second flow channel is used for the circulation of the refrigerant, so as to realize the heat exchange between the two media. Since the basic structure and working principle of the plate heat exchanger are well known by those skilled in the art, details will not be repeated in the specific implementation manner of the present application.
[0028] Please refer to Figure 1 to Figure 13 As shown, an embodiment of the present application discloses a heat exchange plate 100 of a plate heat exchanger, which includes a refrigerant inlet 11, a refrigerant outlet 21, an inlet area 1 surrounding the refrigerant inlet 11, a sur...

The invention provides a plate heat exchanger and a heat exchange plate thereof. The heat exchange plate comprises an inlet area surrounding a refrigerant inlet, an outlet area surrounding a refrigerant outlet, a first main heat exchange area connected with the inlet area and a second main heat exchange area connected with the outlet area. A plurality of first protruding points are arranged in thefirst main heat exchange area, and a plurality of second protruding points are arranged in the second main heat exchange area. The size of the first protruding points in the width direction of the heat exchange plate is larger than the size of the second protruding points in the width direction of the heat exchange plate. The size of the first protruding points in the width direction of the heatexchange plate is larger than the size of the first protruding points in the length direction of the heat exchange plate. By means of the arrangement, heat exchange of the first main heat exchange area is enhanced, the evaporation triggering effect of a refrigerant is achieved, and the heat exchange performance of the plate heat exchanger and the heat exchange plate of the plate heat exchanger isimproved.
Description
technical field [0001] The application relates to a plate heat exchanger and its heat exchange plates, belonging to the technical field of heat exchange. Background technique [0002] Plate heat exchangers are recognized as highly efficient and compact heat exchangers, which can be used for heat exchange between two media (such as brine and refrigerant), and have been widely used in refrigeration and air conditioning, new energy vehicles and other industries. In the plate heat exchanger in the related art, a plurality of stacked heat exchange plates form mutually spaced channels for the flow of two fluids, and a number of raised dot structures are arranged in the heat exchange area of the plates for the flow of the two fluids. In the process of heat exchange, the heat exchange is enhanced to improve the heat exchange performance of the plate heat exchanger. [0003] However, there is still room for improvement in the related art to further optimize the heat exchange effec...
