To deal with this problem, a sliding vane rotary pump was developed and tested in a two-phase electronic evaporative cooling system, and the working performance was investigated and analyzed based on the experimental data. The effect of the suction port size was studied. In a two-phase cooling system, the volumetric efficiency decreased with the rotary speed. The discharge valve had no fatal influence on the stable working performance of the pump. However, it highly affected the volumetric efficiency in high rotary speed while it acted insignificantly in the low speed. A stable cooling result could be quickly obtained during the change of the heat flux with the driving of the sliding vane pump, and a minor dependence between flow rates was detected, which was caused by the pressure rise. Therefore, the sliding vane pump was able to be an alternative pump for the two-phase electronic direct cooling system.
