Embodiment Construction

[0014] To solve the problems of complex structure, low reliability, and heat-dissipating shell of the liquid-cooled computer board pressure relief device, the general idea is to reserve some space on the heat-dissipating shell. If the volume of cooling liquid increases, the increased part can be occupied The space reserved on the heat dissipation shell, so as to avoid damage to the heat dissipation shell due to temperature rise.

[0015] Based on the above ideas, the present invention provides a simple structure to achieve the purpose, which is as follows: the liquid-cooled computer board pressure relief element includes a heat dissipation housing arranged in the liquid-cooled computer, one side of the heat dissipation housing and a heat conduction pad One side is closely attached, and the other side of the heat conduction pad is closely attached to the heating chip for heat conduction. The heating chip is arranged on the printed board, and the printed board is fixedly arranged...

Abstract

The invention provides a board card pressure relieving device for a liquid-cooled computer, which mainly solves the problems of complex structure and low reliability of the existing board card pressure relieving device for the liquid-cooled computer. The board card pressure relieving device for the liquid-cooled computer, which is provided by the invention, comprises a heat dissipating shell arranged in the liquid-cooled computer, wherein one end part of a cooling liquid flow channel of the heat dissipating shell is provided with a pressure relieving element; the pressure relieving element is fixedly arranged on the heat dissipating shell and forms a sealed cooling liquid flow channel with the heat dissipating shell; the pressure relieving element is a rubber pressure relieving element which cannot be corroded by cooling liquid; and a blind hole contacted with external air is arranged in the pressure relieving element. The board card pressure relieving device for the liquid-cooled computer, which is provided by the invention, has the advantages of simple structure and high reliability, and the problem of cooling liquid pressure relief occurring after the heat dissipating shell of a board card is heated is effectively solved.

Description

technical field [0001] The invention relates to a pressure relief device for a liquid-cooled computer board, which belongs to the structure of avionics equipment. Background technique [0002] With the development of microelectronics technology, the power consumption of chips is getting higher and higher, and the traditional natural heat dissipation and forced air cooling can no longer solve the heat dissipation problem of chips. Compared with air, the specific heat capacity of liquid is many times higher, so liquid cooling is a better way to solve the heat dissipation of high power consumption chips. The computer is cooled by liquid, and the heat on the board is generally taken away by the liquid flowing inside the heat dissipation housing of the computer board. As a result, the coolant fills the cooling case of the board and the coolant channels of the computer case. [0003] Expansion with heat and contraction with cold is an inherent property of matter, and cooling liq...
