ABSTRACT:
A thermal energy transfer device having controllably variable thermal conductance comprises a reflux heat pipe having a capillary wick therein, an evaporator and a condenser zone, a circulating supply of working fluid which is controlled by a bendable section in the heat pipe body and an external device to control the bend in the heat pipe body, thereby controlling the amount of liquid returning to the evaporator. As returning liquid condensate is trapped in the center of the deformed tube, less liquid is available for evaporation in the evaporator. This results in a low liquid level that saturates only a portion of the evaporator wick. This results in higher thermal impedance. If the heat pipe body is deformed so that all liquid is trapped in the deformed portion, no liquid is available in the evaporator and there is a high thermal impedance.
