The current collector 10 is mainly composed of a current collector 18, a partition 12, an end cover, etc. The partition 12 is used to separate the flow. In order to facilitate the assembly and welding of the harmonica tube 20, the assembly hole of the harmonica tube 20 on the current collector 18 adopts a flanging punching 13, such as Figure 1 , Figure 2 The partition 12 is a thin-walled part, generally 1.2 mm or 1.5 mm, and the partition assembly groove 11 on the collector 18 is generally cut by sawing. The partition 12 is difficult to assemble, the welding area is small, and there is a leakage problem at the partition 12. If there are multiple processes on the cold plate, there will be multiple partitions 12, and multiple partition 12 grooves need to be sawed.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0030] Example 1

[0031] like Figure 3-5 As shown, in order to solve the problem in the prior art that the overall strength of the manifold 18 is weakened and the leakage points increase, which affects the product performance. This embodiment proposes a harmonica tube water cooling plate collector 10 structure, including a manifold 18, the surface of which is provided with punching holes 15; a harmonica tube 20 assembly connector, the main body of which is a plate-like structure, the surface of the harmonica tube 20 assembly connector is provided with hollow channels, the harmonica tube 20 assembly connector is welded to the outer surface of the manifold 18, and the hollow channels are opposite to the punching holes 15, and the harmonica tube 20 assembly connector is used to connect the manifold 18 and the harmonica tube 20.

[0032] like Figure 3 As shown, in this embodiment, the side of the current collector 10 is connected to a plurality of harmonica tubes 20, such as Figure 4 As shown, the main body of the current collector 10 is a collecting tube 18, and a punching hole 15 is opened on the side of the collecting tube 18 corresponding to the position of each harmonica tube 20, and the size of the punching hole 15 matches the end shape and structure of the harmonica tube 20, and a first harmonica tube assembly connector 16 is configured at each punching hole 15, and the collecting tube 18 is welded to the first harmonica tube assembly connector 16 at the punching hole 15 to facilitate the subsequent installation of the harmonica tube 20.

[0033] A partition piece 14 is provided inside the manifold 18 to separate two adjacent punching holes 15. The outer contour of the partition piece 14 matches the cross section of the manifold 18, and the edges of the partition piece 14 are welded to the inner wall of the manifold 18. The partition piece 14 has a flange structure facing the same side. During installation, tooling equipment is used to assist the partition piece 14 in being installed in the manifold 18 at the designed position and then welded to separate the flow in the manifold 18. Since the partition piece 14 has a flange structure, the welding area between the partition piece 14 and the manifold 18 can be increased, which can effectively solve the problem of internal leakage at the partition.

[0034] Combination Figure 5 As shown, the edge of the hollow channel of the first harmonica tube assembly connector 16 has an inner flange 161 extending toward the punching hole 15, and the first harmonica tube assembly connector 16 is inserted into the punching hole 15 through the inner flange 161. Since the inner flange 161 is preferably made by stamping, the thickness of the inner flange 161 is consistent with the thickness of the main body of the first harmonica tube assembly connector 16. The end of the harmonica tube 20 is inserted into the hollow channel, which facilitates the positioning process of the manifold 18, the first harmonica tube assembly connector 16 and the harmonica tube 20 before welding.

[0035] Example 2

[0036] like Figure 6 , Figure 7 As shown, the connection method between the harmonica pipe 20 and the manifold 18 in this embodiment is similar to that in Embodiment 1, except for the direction of the flanging of the first harmonica pipe assembly connector 16 .

[0037] In the present embodiment, the flange direction of the first harmonica tube assembly connector 16 in Example 1 is reversed to form a second harmonica tube assembly connector 17, and the edge of the hollow channel of the second harmonica tube assembly connector 17 has an outer flange 171 extending in the direction away from the punching hole 15, and the harmonica tube 20 is inserted into the outer flange 171, which can also facilitate the positioning process of the collecting pipe 18, the first harmonica tube assembly connector 16 and the harmonica tube 20 before welding to a certain extent.

[0038] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
