Embodiment Construction
[0024] Plate heat exchanger is an efficient and compact heat exchanger, which can be widely used in refrigeration and air conditioning, new energy vehicles and other industries. refer to Figure 2 to Figure 15 In one embodiment of the present application, a plate heat exchanger 10 is provided. The main core part of the plate heat exchanger 10 includes a number of stacked plates 100. The plate heat exchanger 10 also includes a main heat exchange core There are several external connection pipes 20 on one side in the thickness direction of the body, and the external connection pipes 20 are used to connect other system components.
[0025] The number of plates 100 includes at least one set of adjacent first plates 101 and second plates 102 . Several plates 100 can also have multiple groups of adjacent first plates 101 and second plates 102, the first plates 101 and the second plates 102 are arranged alternately, and each plate 100 includes a front face 1001 arranged opposite to e...

The invention relates to a plate heat exchanger. The plate heat exchanger comprises a plurality of plate sheets arranged in a stacked mode. The plate sheets comprise one or more groups of first platesheets and second plate sheets, which are adjacent. Any one of the first plate sheets and the second plate sheets is provided with a base plate part and a plurality of protruding parts, which are located in a main heat exchange area. The base plate part is arranged in a planar manner on the front surface and the back surface of the corresponding plate sheet. The protruding parts protrude from thebase plate parts on the front surfaces of the corresponding plate sheets. Each base plate part comprises a plurality of intersection parts and a plurality of channel parts, wherein the channel parts are connected between every two adjacent intersection parts in the first extending direction, and the channel parts are connected between every two adjacent protruding parts in the second extending direction. The maximum size of the channel parts in the second extending direction is smaller than or equal to the size of the channel parts in the first extending direction. The protruding parts on thefront surfaces of the first plates make contact with at least part of the channel parts on the back surfaces of the second plates, and pits formed in the back surfaces of the second plates, of the protruding parts of the second plates are opposite to at least part of the channel parts on the front surfaces of the first plates. The plate heat exchanger has good heat exchange performance.
Description
technical field [0001] The present application relates to the technical field of heat exchange, in particular to a plate heat exchanger. Background technique [0002] Generally, a plate heat exchanger includes a plurality of plates, which are stacked together by means such as brazing, and the space between the plates is used for the circulation of heat exchange fluid. [0003] In the related art, for example figure 1 In the structure of the heat exchange plate shown, the surface of the plate body 11 of the heat exchange plate is provided with a plurality of concave parts 12 and convex parts 13, and the adjacent concave parts 12 are connected by a curved surface transition, and the bottom of the curved surface is higher than the concave part 12 bottom of. When the heat exchange fluid flows through the channels formed between adjacent heat exchange plates, the protrusions 13 are conducive to strengthening the fluid distribution effect in the lateral direction, and vortices c...
