Abstract
A two-phase heat transfer system including at least one two-phase evaporator, at least one condenser, a vapor conduit joining a vapor outlet of the two-phase evaporator to an inlet of the condenser, a liquid conduit joining an outlet of the condenser to a liquid inlet of the two-phase evaporator, and a thermally-actuated capillary flow valve. The thermally-actuated capillary flow valve having a valve inlet, a valve outlet, a thermal connection to a heat sink for cold biasing the capillary flow valve, a porous wick extending across the flow passageway of the capillary flow valve, and a heater thermally connected to the capillary flow valve, where actuation of the heater evaporates liquid in the porous wick to allow passage of vapor through the capillary flow valve.
