Abstract
A two-phase heat transfer system includes an evaporator, a condenser, a vapor line, and a liquid return line. The evaporator includes a liquid inlet, a vapor outlet, and a capillary wick having a first surface adjacent the liquid inlet and a second surface adjacent the vapor outlet. The condenser includes a vapor inlet and a liquid outlet. The vapor line provides fluid communication between the vapor outlet and the vapor inlet. The liquid return line provides fluid communication between the liquid outlet and the liquid inlet. The wick is substantially free of back-conduction of energy from the second surface to the first surface due to an increase in a conduction path from the second surface to the first surface and due to suppression of nucleation of a working fluid from the second surface to the first surface to promote liquid superheat tolerance in the wick.
