[0019] EMBODIMENT

[0020] Please refer to Figure 2 In the embodiment, a structure for enhancing welding strength of a product is provided, which comprises a cover plate 1, an upper edge sheet 2 is arranged on the lower side of the cover plate 1, a plurality of small inner sheets 3 and large inner sheets 4 are arranged on the lower side of the upper edge sheet 2 in an alternating manner, and a lower edge sheet 5 is arranged on the lower side of the lowermost large inner sheet 4, a bottom plate 6 is arranged on the bottom of the lower edge sheet 5, and the cover plate 1, the upper edge sheet 2, the small inner sheets 3, the large inner sheets 4, the lower edge sheet 5 and the bottom plate 6 together constitute the main structure of a cooler, and the cooler is a structure of an existing product, and the specific working principle is not described here;

[0021] However, the technical solution of the present application is improved for the small inner sheets 3 and the large inner sheets 4, which will be described in detail as follows:

[0022] A fixing shaft 11 is arranged in the middle of the cover plate 1, the fixing shaft 11 is fixedly installed with the cover plate 11 through a shaft sleeve 12, meanwhile, two pipe connectors 13 are arranged on the cover plate 1 at both sides of the fixing shaft 11, the pipe connectors 13 are cooling liquid pipes, and a welding ring 14 is arranged between the pipe connectors 13 and the cover plate 1, the welding ring 14 helps to braze the bottom of the pipe connector 13 on the cover plate 1;

[0023] A center hole is arranged at the center of the upper edge sheet 2, the small inner sheet 3, the large inner sheet 4, and the lower edge sheet 5 and the bottom plate 6, symmetric through holes are arranged at the positions corresponding to the two pipe connectors 13 at the circumferential side of the center hole, the through holes are used to realize the flow of the cooling liquid, four through holes are arranged on the small inner sheet 3 and the large inner sheet 4 in an equal interval, the four through holes on the small inner sheet 3 and the large inner sheet 4 correspond to each other in position;

[0024] Among them, two upper bosses A31 are arranged on the upper surface of the small inner sheet 3 at the positions of the two symmetric through holes, and lower bosses A32 are arranged at the lower side of the other two symmetric through holes (as shown in Figure 3 、 ​ A convex 7 is arranged at the outer edge of the upper boss A31, the number of the convex 7 is at least two, the convex 7 is symmetrically arranged about the center line of the upper boss A31, in actual application, the number of the convex 7 can also be three, four, etc., but the distribution of the convex 7 is uniform;
