[0020] In order to make the purpose, technical scheme and advantage of the embodiment more clear and obvious, the utility model is further explained in detail below by combining with the drawings and embodiment. When the following description relates to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementation described in the following exemplary embodiments does not represent all the implementations consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0021] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0022] Example 1

[0023] like Figures 1-4 As shown, an integrated condenser plate side plate of this embodiment includes a side plate 1 and two heat exchange plates 2. The side plate 1 is connected between the heat exchange plates 2. The two heat exchange plates 2 are arranged opposite to each other. The side plate 1 is used to seal the side edges between the heat exchange plates 2. The side plates 1 are connected end to end to form a ring structure. The side plate 1 is an integrally formed component.

[0024] The closed frame structure formed by connecting the two sides of the integrally molded side panel has only one welding point, which improves the overall sealing performance of the side panel area.

[0025] Preferably, the heat exchange plate 2 is a rectangular plate, and the side plate 1 forms a rectangular frame that cooperates with the heat exchange plate 2. The side plate 1 includes multiple bends.

[0026] The side plate of a certain length is bent by heating at high temperature, so that the one-piece side plate can be bent multiple times to form multiple bent parts, which are then welded to the side edges of two parallel rectangular heat exchange plates. The side plate formed by the bending process constitutes a closed frame structure, and the vertical bends of the closed frame structure always maintain a smooth one-piece connection.

[0027] The bending process in this embodiment is a hot bending process. The metal side plate 1 is heated to a certain temperature to make it soft and easy to bend. Then, a certain force is applied to bend it. After cooling, the side plate 1 retains the required shape to form a bent part.

[0028] The heat exchange plate 2 is a rectangular plate, and the bent portion forms a rectangular frame that mates with the heat exchange plate 2. The bent portion includes a first bent portion 11, a second bent portion 12, a third bent portion 12, and a fourth bent portion 14. The first bent portion 11 is used for the first welding with the heat exchange plate 1, and the first bent portion 11 and the fourth bent portion 14 are welded together end to end.

[0029] In another embodiment, the heat exchange plate can also be circular or other polygonal in shape. The side plate 1 is heated and bent according to the different shapes of the heat exchange plate. The side plate 1 can be adapted to more types of heat exchange plates 2, which improves the flexibility of side plate sealing in the field of heat exchanger technology.

[0030] Example 2

[0031] like Figure 2As shown, the heat exchange plate 2 in this embodiment has side plate mounting positions 21 around its inner side. The width of the side plate 1 is the height of the gap between the two heat exchange plate sides. The side plate 1 abuts against the side plate mounting positions 21 of the heat exchange plate 2. The side plate 1 is used to provide support for the heat exchange plate 2.

[0032] The side plates are abutted against the side plate mounting positions 21 of the two heat exchange plates respectively, so that the heat exchange plates and the side plates can support the heat exchange plane during actual use, and prevent the heat exchange plate edges from collapsing or cracking.

[0033] In this embodiment, the side plates are placed between the heat exchange plates 2. The length of the side plates 1 is set to cover the circumference of the side of the heat exchange plates 2, so that the side plates 1 can seal the refrigerant layer formed by the heat exchange plates 2. When the length of the side plates 1 is too long, it can be adjusted to a suitable sealing position by cutting.

[0034] In another embodiment, the side plate 1 can be mounted on the outer wall of the side of the heat exchange plate 2. During the welding process, the side plate can be positioned on the outer wall of the heat exchange plate when it is bent. However, the side plate 2 in this way cannot support the side of the heat exchange plate 2, and its load-bearing capacity is worse than that of the side plate mounting position 21 on the inner side of the heat exchange plate.

[0035] Example 3

[0036] like Figures 2-4 As shown, in this embodiment, multiple parallel reinforcing ribs 3 are installed between the heat exchange plates 2, and the multiple reinforcing ribs 3 are staggered to form Z-shaped refrigerant flow channels. The staggered arrangement of the reinforcing ribs 3 enables the heat exchange layers between the heat exchange plates 3 to form interconnected refrigerant flow channels, thereby increasing the flow time of the heat exchange medium in the heat exchange layer inside the heat exchange plates and improving the heat exchange effect.

[0037] The extension of the reinforcing rib 3 is perpendicularly connected to the side panel mounting position 21. During the bending process of the side panel 1, two of the bent parts can be positioned by the reinforcing rib 3, and the positioning of the reinforcing rib 3 allows the bent parts to bend to a suitable angle to form a more precise rectangular frame structure.

[0038] The reinforcing rib plate 3 is perpendicular to the first bending part 11 and the third bending part 13. In the scheme, the first bending part is arranged to be perpendicular to the reinforcing rib plate 3, so that the side plate 1 is firstly welded at the side plate mounting part 21 which is perpendicular to the reinforcing rib plate 3, the first bending part 11 is preliminarily and accurately positioned by the reinforcing rib plate 3, the second bending part 12 is positioned by the auxiliary tool, the third bending part 13 is positioned again by the reinforcing rib plate 3, and finally, the fourth bending part 14 is welded directly with the first end of the first bending part 11 after being positioned, so that the fourth bending part 14 can also be directly welded, and the welding mode of the scheme can be accurately and quickly positioned three times without the auxiliary tool, thereby improving the welding efficiency of the side plate.

[0039] In another embodiment, the first bending part 11 can be welded by the auxiliary tool on the side parallel to the reinforcing rib plate 3, so that the second bending part 12 and the fourth bending part 14 are perpendicular to the reinforcing rib plate 3, the second bending part 12 and the fourth bending part 14 are quickly positioned by the reinforcing rib plate 3, and the third bending part 13 also needs to be positioned by the auxiliary tool, so that the welding efficiency is lower than that of the reinforcing rib plate 3 which is perpendicular to the first bending part 11 and the third bending part 13.

[0040] A condenser includes a condenser sheet.

[0041] The above is only an embodiment of the present application, and the well-known specific structure and characteristics in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
