[0003] The main function of the water cooling plate is to remove heat through the coolant flowing inside, so as to dissipate heat efficiently for the product. It is usually composed of coolant, water pump, water cooling head, radiator, water tank and other components. It transfers the heat generated by the high-temperature hardware to the coolant, and then circulates the coolant to the water cooling head with the help of the water pump, thereby removing the heat generated by the hardware and achieving the purpose of lowering the hardware temperature. The water cooling plate is widely used in new energy vehicle battery packs, energy storage batteries, data center base stations, supercomputers and other fields, and is a key heat dissipation component.

[0020] The two ends of the upper heat exchange tube 20 and the lower heat exchange tube 30 correspond to each other and are aligned, and the corresponding ends on the same side of the upper heat exchange tube 20 and the lower heat exchange tube 30 are connected to the same connector 40, and the side walls of the two connectors 40 are connected to the liquid connecting pipe 50. The connector 40 is also a copper part, and the liquid connecting pipe 50 is a 304 stainless steel part.

[0021] Furthermore, the cross-section of the flow channel in the middle of the upper heat exchange tube 20 and the lower heat exchange tube 30 is semicircular, the top surface of the upper heat exchange tube 20 is on the same plane as the top surface of the water-cooled plate body 10, and the bottom surface of the upper heat exchange tube 20 is an arc-shaped wall surface, which cooperates with and fits tightly against the bottom surface of the upper mounting groove 11, and the upper heat exchange tube 20 is clamped in the upper mounting groove 11.

[0022] The bottom surface of the lower heat exchange tube 30 is in the same plane as the bottom surface of the water cooling plate body 10 , and the top surface of the lower heat exchange tube 30 is an arc-shaped wall surface which matches and fits tightly with the top surface of the lower mounting groove 11 , and the lower heat exchange tube 30 is clamped in the lower mounting groove 11 .

[0023] Furthermore, the water-cooling plate body 10 is formed with a plurality of heat exchange through holes 12 extending vertically and extending out of the top and bottom surfaces of the water-cooling plate body 10. This can achieve ventilation, thereby improving the heat exchange effect.

[0024] Furthermore, the mounting groove 11 includes a U-shaped groove section, and both ends of the U-shaped groove section are formed with arc-shaped groove sections extending forward from the front wall of the water-cooled plate body 10. The upper heat exchange tube 20 and the lower heat exchange tube 30 cooperate with the mounting groove 11, and the arc-shaped wall surfaces of the upper heat exchange tube 20 and the lower heat exchange tube 30 are pressed against the inner wall surfaces of the corresponding mounting groove 11.

[0025] The connecting head 40 is a cylindrical sleeve, a bottom end plate is formed at the bottom end, and an annular groove is formed on the inner wall of the top end. The upper cover body 41 is inserted into the upper end of the cylindrical sleeve, the edge of the upper cover body 41 is stuck in the annular groove, the outer wall of the upper cover body 41 is pressed against the inner wall of the annular groove, and the outer wall of the upper cover body 41 is welded and fixed to the upper end of the connecting head 40.

[0026] The upper and lower parts of the rear wall of the cylindrical casing are both formed with mounting through holes, and the ends of the upper heat exchange tube 20 and the lower heat exchange tube 30 are clamped in the corresponding mounting through holes and fixed by welding.

[0027] A front through hole is formed in the middle of the front wall of the cylindrical sleeve, and the rear end tube portion of the liquid connecting tube 50 is clamped on the inner side wall of the corresponding front through hole and fixed by welding.

[0028] Furthermore, a plurality of rear slots 13 are formed on the rear wall surface of the water-cooling plate body 10 for installation at corresponding positions.

[0029] When this embodiment is in use, one liquid connecting pipe 50 is connected to the return liquid pipe, and the other liquid connecting pipe 50 is connected to the liquid inlet pipe. The heat exchange liquid enters the corresponding connecting head 40 from one liquid connecting pipe 50, and then enters the upper heat exchange tube 20 and the lower heat exchange tube 30. Heat is exchanged with the water-cooled plate body 10 through the upper heat exchange tube 20 and the lower heat exchange tube 30, so that the heat on the water-cooled plate body 10 is taken away. During heat exchange, external wind can flow through the heat exchange through hole 12 to achieve heat exchange.

[0030] After the heat exchange liquid in the upper heat exchange tube 20 and the lower heat exchange tube 30 exchanges heat, it enters the corresponding connecting head 40 and then flows out from the corresponding liquid connecting tube 50 to achieve heat exchange. The upper heat exchange tube 20 and the lower heat exchange tube 30 are used to exchange heat with the water-cooled plate body 10, and the heat exchange effect is good and the efficiency is high.

[0031] The specific manufacturing method of this embodiment is:

[0032] First, the mounting grooves 11 are stamped on the top and bottom surfaces of the water-cooling plate body 10 . At the same time, the top and bottom surfaces are milled by CNC to form two planes, and a finishing allowance of 0.30 mm is reserved.

[0033] The upper heat exchange tube 20 and the lower heat exchange tube 30 are respectively pressed into the installation groove 11 of the water-cooled plate body 10 by a 45T punch to achieve fixation. At this time, the bottom surface of the upper heat exchange tube 20 matches and fits tightly with the bottom surface of the upper installation groove 11, and the top surface of the lower heat exchange tube 30 matches and fits tightly with the top surface of the lower installation groove 11.

[0034] Then, two connectors 40 are placed into the ports of the upper heat exchange tube 20 and the lower heat exchange tube 30, and the ends of the upper heat exchange tube 20 and the lower heat exchange tube 30 are inserted into the corresponding mounting through holes of the connectors 40 and fixed by high-frequency welding;

[0035] The upper cover 41 is placed into the top of the connector 40 and fixed by high frequency welding.

[0036] Then, the rear end tube portion of the liquid connecting tube 50 is clamped on the inner side wall of the corresponding front through hole and fixed by high-frequency welding.

[0037] Then, an airtight test is performed, the two liquid connecting pipes 50 can be connected to the connecting pipe to achieve ventilation, and then immersed in water to observe whether bubbles appear. If there are bubbles, it means that the product is unqualified and has tiny pores, and needs to be repaired.

[0038] Then, grind and polish it to remove the uneven solder accumulation caused by welding and remove the excess solder;

[0039] Clean the welding slag at the welding joint, and fill the gap between the upper heat exchange tube 20, the lower heat exchange tube 30 and the water cooling plate body 10 with epoxy resin glue through a needle tube, so that the upper heat exchange tube 20, the lower heat exchange tube 30 and the aluminum part are firmly bonded and the heat exchange effect is improved;

[0040] CNC milling is performed by CNC milling to remove the reserved 0.30 mm margin to achieve the flatness of the water-cooling plate body 10 and the upper heat exchange tube 20 and the lower heat exchange tube 30.

[0041] A 4 mm single crystal cutter is mounted on a cutter head with a diameter of 100 to ensure that the flatness of both sides of the water cooling plate body 10 is within 0.05 mm.

[0042] The top and bottom surfaces of the water-cooling plate body 10 are treated with 240# non-woven fabric to achieve a smoothness of 3.2;

[0043] Then clean it and use a cleaning agent to clean the oil stains on the product.

[0044] For copper protection, use YDH2000-72 copper antioxidant to put the product into the solution and soak it at room temperature for 3-5 minutes to form a 2-5um film on the surface of the copper parts to prevent oxidation of the copper tube. à Check the packaging.

[0045] During the processing, when the upper heat exchange tube 20 and the lower heat exchange tube 30 are riveted respectively by a 45T punch, the riveting needs to ensure that they are consistent with the installation groove 11 of the water-cooled plate body 10, and the upper heat exchange tube 20 and the lower heat exchange tube 30 cannot be damaged and the plane concave is less than 0.15.

[0046] In the processing process of this embodiment, three weldings are adopted. The first high-frequency welding temperature is 900-950 degrees, the second high-frequency welding temperature is 800-850 degrees and needs to be cooled, and the third high-frequency welding temperature is 800-850 degrees and needs to be cooled.

[0047] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
