Pump-driven two-phase loop air conditioner backboard heat dissipation system for data center

The pump-driven two-phase loop air conditioner backboard heat dissipation system for the data center comprises a working medium pump driving part, a backboard evaporation heat dissipation part and a gas-liquid separation heat exchange part, and the working medium pump driving part comprises a liquid storage tank and a working medium pump; the back plate evaporation heat dissipation part is a back plate evaporator; the gas-liquid separation heat exchange part comprises a gas-liquid separator, a compressor driving gas-phase heat dissipation sub-part and a liquid-phase heat dissipation sub-part; the working medium pump and the one-way valve can be arranged in parallel, and the compressor and the one-way valve can be arranged in parallel. The system is high in operation reliability and low in cost; gas-liquid separation can be achieved through the gas-liquid separation part, and stable gas-liquid separation under the dryness fluctuation state of the heat dissipation working medium is achieved through self-adaptio
