Heat dissipation device of mobile cabinet level server system and thermal management method of heat dissipation device

Abstract

The invention relates to a heat dissipation device of a mobile cabinet level server system. The heat dissipation device comprises a plurality of water-cooling hot pipe heat dissipation modules, a pipeline system, a rear door heat dissipation device and a control system, wherein the plurality of water-cooling hot pipe heat dissipation modules are arranged in a mobile cabinet, each electronic equipment needed to be cooled in the mobile cabinet is corresponding to one of the water-cooling hot pipe heat dissipation modules, accurate heat dissipation of a heating part can be achieved, and the heat dissipation efficiency is substantially improved; compared liquid cooling with traditional air cooling, a medium of liquid cooling is relatively large in specific heat capacity, more heat can be taken away, meanwhile, the heat dissipation device is relatively quite during running, and noise can be reduced very well; a hot pipe is good hot conductor, is high in safety coefficient and low in cost and is widely used in the field of heat dissipation, the problem of heat dissipation of a high-flux density component in the field of heat dissipation can be solved very well by combining water cooling and the hot pipe, and the reliability of the component is improved; compared with air cooling, the noise of the hot pipe can be reduced; and a liquid cooling system is low in power during normal working, and more energy is saved.

Description

technical field [0001] The invention relates to the field of server heat dissipation, in particular to a heat dissipation device and a heat management method for a mobile cabinet-level server system. Background technique [0002] In recent years, cloud computing has become the third revolution of IT industry after personal computer and Internet revolution. The revolution brought about by cloud computing is to transform IT infrastructure into basic social public facilities like water and electricity. This is of great significance for effectively helping the majority of small and medium-sized enterprises to strengthen independent innovation, reduce operating costs, shorten R&D cycles, and control technological risks. In the global market, the cloud computing industry has entered a growth stage, and the scale of my country's cloud computing market exceeds 117.3 billion yuan. [0003] The traditional data center has a large initial investment and low resource utilization. Ther...

Problems solved by technology

[0003] The traditional data center has a large initial investment and low resource utilization. Therefore, the application of the mobile rack-level server system is born. It can flexibly provide cloud platform solutions and is widely used in production, life, education, medical care, network security, etc.

However, at present, the system is restricted by heat dissipation, and it will generate a large amount of heat when it is working. The traditional heat dissipation device and heat dissipation method is to directly use the fan to supply air, and the air flows to exchange heat for heat dissipation. The heat dissipation effect is poor, and the server is in danger of downtime. The reliability is low, and at the same time, in a quiet office environment, the noise is relatively large, which has a relatively large impact on the office environment
