High-efficiency data center server phase change liquid cooling method

By adding phase change capsules to the phase change coolant and using their vaporization expansion to float away the bubbles on the server surface, the problem of low heat dissipation efficiency caused by bubble attachment is solved, and more efficient server cooling is achieved.

Abstract

The invention discloses a high-efficiency data center server phase change liquid cooling method, which comprises the following steps of: soaking servers which are vertically arranged and horizontally arranged at intervals in phase change cooling liquid, and cooling the servers by virtue of gasification of the phase change cooling liquid. The gasified phase-change cooling liquid gas rises to the upper end of the phase-change cooling liquid chamber, then exchanges heat with the cooling device, is liquefied and falls to the lower part, and is characterized in that a plurality of phase-change capsules are added into the phase-change cooling liquid, so that the heated and gasified phase-change capsules take away bubbles on the outer side surface of the server upwards in the rising process. The air bubble adhesion rate on the surface of the server can be better reduced so as to improve the heat dissipation effect, the heat dissipation device has the effects of being simple in structure, stable and reliable in operation, capable of achieving self-adaptive adjustment according to the calorific value and the like, the heat dissipation efficiency of the server is greatly improved, and the overall performance of the server is guaranteed.
