Abstract: A vapor/liquid condensation system includes a condensation unit and an evaporation unit. The condensation unit is connected with the evaporation unit via conduits. The evaporation unit has a liquid inlet, a vapor outlet and an evaporation chamber in communication with each other. The evaporation unit converts liquid-phase working fluid into vapor-phase working fluid, which spreads to the condensation unit. The condensation unit cools and condenses the vapor-phase working fluid into liquid-phase working fluid, which goes back the evaporation unit. After the vapor-phase working fluid enters the condensation unit, the vapor-phase working fluid is distributed and condensed into liquid-phase working fluid. Then the liquid-phase working fluid is collected and then goes back to the evaporation unit. The length of the pipeline is shortened and the pipeline pressure is lowered to avoid interruption of heat dissipation circulation and failure in heat dissipation.
