A valved heat pipe and an adaptive circuit cooling system using it are disclosed. The valved heat pipe includes a sealed tube, liquid in the tube, and at least one valve in the tube. This valve operates as a function of temperature to selectively obstruct circulation of the liquid from one end of the tube to the other. The adaptive cooling system includes heat generating equipment, e.g., electronic circuitry such as radio frequency transmitters and/or recievers, a heat sink and such a valved heat pipe that thermally connects the circuitry to the heat sink.
