Description

Liquid cooling server

Technical Field

The utility model relates to a liquid cooling server.

Background

In the prior art, servers are generally cooled by air cooling, and the air cooling has the problems of large contact thermal resistance, large heat convection thermal resistance and large total thermal resistance in the heat transfer process, so that the heat exchange efficiency is low. In order to ensure a larger temperature difference between high and low temperature heat sources in the heat exchange process, a lower external low temperature heat source is needed to guide the heat exchange process. For the server, the air cooling method alone is not enough to meet the requirement of the server with high heat flux density on the heat dissipation performance.

Another method for dissipating heat from the server in the prior art is a liquid cooling method, i.e. using working fluid as a medium for intermediate heat transfer, and transferring heat from the hot zone to a remote location for cooling. The difference with the indirect refrigeration of forced air cooling is that the liquid cooling mode is direct to the heat source the refrigerant, in addition because the specific heat capacity of liquid ratio air is a lot more, and the radiating rate is also greater than the air far away, therefore the refrigeration efficiency of liquid cooling mode is far higher than the heat dissipation of forced air cooling mode, and the heat that every unit volume transmitted is compared with the forced air cooling mode and is the radiating efficiency improvement reach 3300 times.
