[0025] The present application is further described below with reference to the accompanying drawings and specific embodiments:

[0026] Combination Figure 1-Figure 3 The present application embodiment provides a processing technology for a mounting plate 1, including:

[0027] Providing workpieces to be processed;

[0028] Forming multiple mounting plates 1: Use a stamping die to stamp the workpiece to be processed to form multiple mounting plates 1; along the first direction, multiple mounting plates 1 are aligned and arranged along the first direction, and adjacent mounting plates 1 can be arranged in close contact. In this way, there is no waste or very little waste between two adjacent mounting plates 1 formed by stamping, and the workpiece to be processed of the same size can form more mounting plates 1, which is conducive to improving the material utilization rate of the workpiece to be processed; improving the material utilization rate can save materials, which can reduce the manufacturing cost of the heat exchanger 100. In this application, the workpiece to be processed is in the shape of a flat plate.

[0029] In the step of forming the mounting plate 1, the stamping die stamps the workpiece to be processed along the transmission direction of the workpiece to be processed, and stamps out each mounting plate 1 in sequence. In this embodiment, the workpiece to be processed moves along the transmission direction, and the stamping die stamps different positions of the workpiece to be processed, and forms each mounting plate 1 in sequence. Usually, the thickness of the mounting plate 1 is relatively large, and forming each mounting plate 1 in sequence is conducive to controlling the formation and size of the mounting plate 1. In other embodiments, multiple mounting plates 1 can also be stamped out at the same time.

[0030] In this embodiment, forming the mounting plate 1 includes the following steps: cutting the outer shape - shaping - precision cutting - forming the first positioning portion 14 - punching - dropping the product

[0031] Forming the mounting plate 1 of a preset size and shape includes cutting the shape: a stamping die punches out the mounting plate 1 close to the preset size and shape;

[0032] Molding the mounting plate 1 of a preset size and shape also includes shaping: the mounting plate 1 processed by cutting the outer shape has burrs or insufficient flatness, and the outer shape of the mounting plate 1 needs to be shaped to improve the flatness of the mounting plate 1, and the surrounding burrs need to be processed, so that the outer shape of the mounting plate 1 is smoother.

[0033] Forming the mounting plate 1 of a preset size and shape also includes precision cutting: if the size of the initially formed mounting plate 1 is not precise, the initially formed mounting plate 1 is precisely cut according to the preset size to obtain a mounting plate 1 with more precise size and smoother shape. The transmission direction described in this application is consistent with the first direction.

[0034] A stamping die is used to stamp the workpiece to be processed, so that the stamped mounting plate 1 has a flange portion 12 and a notch portion 13, and the flange portion 12 and the notch portion 13 are located at both ends of the mounting end, and the notch portion 13 includes a groove 131. The shape of the flange portion 12 is consistent with the shape of the groove 131, and the size of the flange portion 12 is consistent with the size of the groove 131. In this way, after a mounting plate 1 is stamped and formed on the workpiece to be processed, a structure consistent with the size and shape of the flange portion 12 is formed on the workpiece to be processed, which is referred to as a flange body T. The flange body T is the flange portion 12 of the next formed mounting plate 1. In this way, multiple mounting plates 1 can be continuously formed on the workpiece to be processed, and there is almost no waste or very little waste in the process of forming two adjacent mounting plates 1. This can greatly improve the material utilization rate of the workpiece to be processed, which is conducive to reducing costs. In other embodiments, the shape of the flange portion 12 and the shape of the groove 131 can also be similar, and the size of the flange portion 12 is close to the size of the groove 131.

[0035] In this embodiment, the stamped mounting plate 1 has an arc-shaped flange portion 12, the notch portion 13 has a groove 131, and the stamped mounting plate 1 has an arc-shaped groove 131.

Of course, in other embodiments, the stamped mounting plate 1 can also have a rectangular flange portion 12, and the stamped mounting plate 1 has a rectangular groove 131. The shapes of the flange portion 12 and the groove 131 are not limited.

[0036] In the step of forming the mounting plate 1, the stamping die also stamps out a first positioning portion 14 on the mounting plate 1. The first positioning portion 14 is in a convex shape or a groove 131 shape. The first positioning portion 14 is provided for positioning and assembling the mounting plate 1 and other parts.

[0037] In the step of forming the mounting plate 1, after the step of punching out the first positioning portion 14, the stamping die also punches out a mounting hole 121 on the mounting plate 1. The mounting hole 121 is located at the flange portion 12. The mounting plate 1 is generally assembled with other components, such as the heat exchange core 2 of the heat exchanger 100. The mounting hole 121 can install the assembly structure of the mounting plate 1 and other components into the required system.

[0038] In other embodiments, the mounting hole 121 may be processed on the mounting plate 1 first, and then the first positioning portion 14 may be processed and formed on the mounting plate 1 .

[0039] After the mounting plate 1 is processed, the step of removing the product is also included: the formed mounting plate 1 is removed from the workbench.

[0040] The present application also provides a heat exchanger 100, Figure 4-Figure 12The first embodiment of the heat exchanger 100 is shown in FIG. 1 .

For the convenience of description, the upper and lower directions are defined as the upper and lower directions in the attached drawings of the specification. Figure 1 The up and down directions of the heat exchanger 100 are defined as the height direction, length direction, and width direction of the heat exchanger 100 as shown in the attached drawings of the specification.

In this embodiment, the sum of the areas of the mounting plates 1 is smaller than the area of ​​the end plates 3, and the mounting plates 1 are located on one side of the heat exchange core 2 along the height direction of the heat exchanger 100.

The heat exchange core 2 includes a channel 21, and the channel 41 of the pipe 4 is connected to the channel 21 for fluid to flow into or out of the heat exchanger 100. The pipe 4 is fixedly connected to the end plate 3, and the end plate 3 and the heat exchange core 2 can be accurately positioned and assembled, so that the installation position of the pipe 4 on the heat exchanger 100 is also accurate, which is conducive to ensuring the position of the pipe 4. In particular, in the present application, multiple mounting plates 1 are split structures. If the pipe 4 and the mounting plate 1 are welded and fixed, the mounting plate 1 needs to be positioned and assembled with the end plate 3, and then the pipe 4 and the mounting plate 1 are positioned and assembled.

In this solution, the end plate 3 can be accurately positioned and assembled with the heat exchange core 2, and the pipe 4 and the end plate 3 are assembled and fixed. This ensures the position of the pipe 4, so that the channel 41 of the pipe 4 and the channel 21 of the heat exchange core 2 are aligned as much as possible, so that the channel 41 of the pipe 4 and the channel 21 of the heat exchange core 2 are connected to the maximum extent, ensuring smooth flow of the fluid. In addition, the end plate 3 and the heat exchange core 2 are easy to position and assemble, and the pipe 4 and the end plate 3 are also easy to position and assemble.
