Description

Technical Field

[0001] The utility model relates to the technical field of water cooling plates, in particular to a copper-aluminum composite welded water cooling plate. Background Art

[0002] A water cooling plate is a device used for heat dissipation, and is usually used in electronic equipment and other occasions where efficient heat dissipation is required. Traditional water cooling plates are usually made of a single metal with good thermal conductivity, but the heat dissipation effect is not ideal in high power density and high temperature environments.

[0003] Therefore, in order to solve the above technical problems, it is necessary to develop a copper-aluminum composite welded water-cooling plate. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of the utility model is to provide a copper-aluminum composite welded water-cooled plate, in which a heat sink is welded on the bottom plate and accommodated in the cavity of the top cover, thereby improving the heat dissipation effect of the entire water-cooled plate. Connecting holes are provided at both ends of the top cover to facilitate the entry and exit of the fluid, thereby improving the efficiency of the entire water cooling system.

[0005] Technical solution: A copper-aluminum composite welded water-cooled plate, comprising a base plate, a heat sink and a top cover, wherein the heat sink is welded to the end face of the base plate, the top cover is provided with a cavity, the top cover is connected to the base plate, the heat sink is accommodated in the cavity of the top cover, and connecting holes are also provided on both side end faces of the top cover.

[0006] The copper-aluminum composite welded water-cooling plate described in the utility model has the heat sink welded on the bottom plate, which improves the heat dissipation efficiency of the entire water-cooling plate and stabilizes the temperature of the equipment. The top cover provides a closed structure to prevent the entry of external substances and maintain the cleanliness of the heat sink. The connecting holes serve as the inlet and outlet of the coolant, which improves the efficiency of the water cooling system. The heat dissipation medium can effectively take away the heat.

[0007] Furthermore, in the above copper-aluminum composite welded water-cooling plate, the bottom plate and the top cover are made of copper. Copper has excellent thermal conductivity, and its high thermal conductivity enables the bottom plate and the top cover to conduct and disperse heat more effectively in the entire water-cooling plate structure, thereby improving the heat dissipation efficiency of the entire system.

[0008] Furthermore, in the copper-aluminum composite welded water-cooled plate, the heat sink is made of aluminum. Aluminum has a certain corrosion resistance, and the heat sink can prevent corrosion when a liquid cooling medium is used to cool the water in the water cooling system.

[0009] Furthermore, in the copper-aluminum composite welded water-cooled plate, the heat sink is 0.3 mm thick, and the distance between every two adjacent heat sinks is 0.3 mm. By setting a reasonable thickness and spacing of the heat sink, the heat dissipation performance of the entire structure is improved.

[0010] Furthermore, in the above copper-aluminum composite welded water-cooling plate, the end corners of the bottom plate are all blunted. The blunting treatment can reduce the sharp parts of the bottom plate corners and reduce the risk of scratches that may occur during use and installation.

[0011] The beneficial effects of the utility model are:

[0012] The copper-aluminum composite welded water-cooling plate described in the utility model has a reasonable structural design. A heat sink is welded on the bottom plate and accommodated in the cavity of the top cover, thereby improving the heat dissipation effect of the entire water-cooling plate. Connecting holes are arranged at both ends of the top cover to facilitate the inflow and outflow of fluid, thereby improving the efficiency of the entire water cooling system.
