Description

Technical field: [0001] The invention relates to the technical field of equipment heat dissipation, in particular to a heat dissipation device for a circuit board. technical background: [0002] At present, the water-cooled heat dissipation device used by the circuit board of the general computer mainframe includes a water tank body arranged on the inner surface of the mainframe casing, the water tank body is connected with a pump, and the water tank body is connected with a pipe body, the pipe body It is connected to the heat sink group of the heating chip on the circuit board; the heat source of the heating chip can be transmitted to the heat sink group, and at the same time, the pump can output the water in the water tank body through the tube body, and cool down the heat sink group through the tube body. In order to achieve the effect of heat dissipation. [0003] Although the above-mentioned existing heat dissipation device can cooperate with the tube body to cool down...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned existing heat dissipation device can cooperate with the tube body to cool down the heat-generating chip through the heat-dissipating fin group, the effect of heat dissipation can be achieved; The heat sink is connected, so the distance between the water tank body and the heating chip is relatively long, and the pipeline composed of the required pipe body is also relatively long, which not only takes up more space inside the casing, but also causes an increase in cost and the water tank itself. The assembly of the water tank is also more complicated; moreover, when the main computer needs to be repaired or replaced and the casing needs to be removed, it must be removed together with the water tank body and the pipe body, resulting in difficulty in disassembly and easy to cause damage to the original integrity. The main body and pipe body of the water tank were damaged due to careless disassembly; therefore, the existing general water-cooled heat sink cannot meet the needs of actual use
