[0031] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0032] Since there are technical requirements for pipeline processing, for example, the straight section of the pipeline must be guaranteed to be 1.5 times the diameter of the pipeline, and the bending radius of the pipeline must also be guaranteed, the usual direct connection between the pipeline and the heat exchanger cannot ensure the above requirements. Therefore, a flange can be optionally connected to the interface of the heat exchanger to solve the above problems.

[0033] Combination Figures 1 to 3 As shown, according to a specific embodiment of the present application, a plate heat exchanger is provided.

[0034] Specifically, Figure 1As shown, the plate heat exchanger includes a heat exchanger body 1 and a plurality of adapter flanges 2. A plurality of interfaces 11 are provided on the surface of the heat exchanger body 1. The plurality of adapter flanges 2 can be selectively connected to one or more interfaces 11 among the plurality of interfaces 11. The heat exchanger body 1 is connected to at least one of the air-conditioning pipeline and the cooling pipeline through the adapter flange 2, wherein the adapter flange 2 connected to the air-conditioning pipeline is arranged at an angle relative to the horizontal plane.

[0035] In this embodiment, by setting the adapter flange 2 on the interface 11 of the heat exchanger body 1, the heat exchanger body 1 is connected to at least one of the air conditioning pipeline and the cooling pipeline through the adapter flange 2. At the same time, the adapter flange 2 connected to the air conditioning pipeline is set as a bevel flange, which shortens the length of the air conditioning pipeline and can also cancel the air conditioning pipeline on the plate heat exchanger, thereby improving the applicability and versatility of the heat exchanger. At the same time, the adapter flange connected to the air conditioning pipeline is set at an angle, which can better adapt to the layout of the air conditioning pipeline, improve the installation convenience and stability of the heat exchanger, and can be directly connected to the air conditioning system instead of the pipeline, so as to achieve the purpose of shortening the pipeline and saving the layout space.

By connecting the connection port of the electronic expansion valve 4 to the first interface 111, accurate control and regulation of the refrigerant can be achieved, and the refrigeration effect and energy efficiency of the air conditioning system can be improved. The design of the electronic expansion valve 4 allows the refrigerant flow path to be connected to the air conditioning pipeline through the first adapter flange 21, which simplifies the structure and installation process of the air conditioning system and improves the stability and reliability of the system.

[0038] Specifically, a double O-ring structure is used between the electronic expansion valve 4 and the first adapter flange 21. The electronic expansion valve 4 and the first adapter flange 21 are connected by bolts, and the mounting hole is a countersunk hole. The electronic expansion valve 4 and the first interface 111 are connected by bolts. In other embodiments, the connection method between the electronic expansion valve 4 and the first interface 111, the electronic expansion valve 4 and the first adapter flange 21 are not limited to this, and can also be welding, one-piece molding, etc.
