[0002] The cold plate is a product component of a water-cooled radiator. It is a component that exchanges heat through liquid cooling. The heat dissipation principle is to form flow channels in the metal plate. The electronic components are installed on the surface of the water-cooled plate. The internal coolant enters from the inlet of the plate and then takes away the heat of the components from the outlet.

[0003] In the prior art, finished inlet and outlet joints are often made by inserting processed pipe fittings into pre-processed openings, assembling them, and then firmly fixing them by welding.

[0004] However, in actual use, the weld quality of the girth weld will affect the sealing effect of the water-cooled plate, and a sealing gasket is also installed on the surface where the girth weld is located. The sealing effect of the sealing gasket is also affected by the girth weld, thereby affecting the overall service life of the water-cooled plate. Therefore, a water-cooled plate with an improved inlet and outlet structure is proposed to solve the above problems. Summary of the invention

[0020] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please see attached Figure 1 -Attached Figure 4 An embodiment of the present invention provides a water-cooled plate with an improved inlet and outlet structure, including a bottom plate 4, a drill piece 2 is fixedly connected to the upper end of the bottom plate 4, a cover plate 1 is fixedly connected to the upper end of the drill piece 2, a water inlet 6 is opened on the left side of the inner surface of the bottom plate 4, a drain outlet 5 is opened at the rear end of the left side of the inner surface of the bottom plate 4, a water cooling groove 7 is opened at the lower end of the inner surface of the bottom plate 4, and a positioning device 3 is provided on the inner surface of the bottom plate 4.

[0022] A cylindrical groove is provided at the lower end of the inner surface of the base plate 4, so that the positioning cylinder 301 can be installed here. The upper end of the drill piece 2 is fixedly connected to the cover plate 1. Cylindrical through holes are provided at the four corners of the inner surface of the cover plate 1, so that the rotating block 304 can be accommodated therein. The water-cooling groove 7 is arranged in an S shape as a whole, so that the contact area between the water-cooling groove 7 and the cover plate 1 and the base plate 4 can be increased. Four groups of positioning devices 3 are provided, and the four groups of positioning devices are respectively located at the four corners of the cover plate 1, so that the cover plate 1 can be prevented from being offset during welding and transportation.

[0023] Reference Figure 1 , Figure 2 as well as Figure 3 The positioning device 3 includes a rotating block 304, the lower end of the rotating block 304 is fixedly connected to the plug block 302, the lower end of the outer arc surface of the plug block 302 is fixedly connected to the clamping block 303, and the lower end of the inner surface of the bottom plate 4 is fixedly connected to the positioning tube 301.

[0024] The outer arc surface of the rotating block 304 is rotatably connected to the cover plate 1, so that people can fix the position of the cover plate 4 by rotating the rotating block 304 after covering the cover plate 4 above the bottom plate 4. A semicircular groove is provided on the upper surface of the rotating block 304, so that people can use tools to drive it to rotate externally. The outer diameter of the insert block 304 is the same as the inner diameter of the positioning tube 301, so that the insert block 304 can be fully inserted into the interior of the positioning tube 301. The upper end of the inner surface of the positioning tube 301 is provided with a rectangular groove. The slot can accommodate the card block 303 inserted into the positioning tube 301. There are two groups of card blocks 303, which are symmetrically distributed with the center line of the insertion block 302 as the symmetry axis. A circular card slot is set at the lower end of the inner surface of the positioning tube 301. Therefore, when people rotate the rotating block 304, the insertion block 302 and the card block 302 can be driven to rotate at the same time, so that the card block 302 can be embedded in the annular card slot at the bottom of the positioning tube 301 during the rotation process. At this time, the cover plate 4 will not be able to be directly lifted upwards and is not easy to be offset.
