Two-phase flow active-passive type multi-level data center cabinet heat dissipation device and method

Abstract

The invention provides a two-phase flow active-passive type multi-level data center cabinet heat dissipation device and method. A system level structure comprises a cabinet heat dissipation device, a condensate water system, a waste heat recovery device, a liquid storage device, a liquid pump, a gas chamber, a fluid working medium and corresponding pipelines. The structure forms a closed loop, the loop is filled with nitrogen to keep a low-pressure state, and a liquid pump drives pipeline fluid to flow. The gas chamber keeps the gas pressure in the two-phase flow loop relatively stable; the liquid storage device is communicated with the gas chamber, so that enough gas space for enabling phase change to easily occur is provided; the cabinet heat dissipation device can switch an active mode and a passive mode so as to achieve PUE minimization under the good heat dissipation capability. The condensate water system is independent of the loop and provides a cold source for the condensation end of the rack-level thermosiphon. The waste heat recovery device recovers waste heat and keeps the temperature of the working medium at the inlet of the thermosiphon stable. The device has the advantages of high integration level, automatic control, multi-stage structure heat dissipation and excellent energy efficiency ratio.
