Abstract: A pump-augmented Loop Heat Pipe (LHP) includes a conventional LHP evaporator/reservoir assembly; one or more additional evaporators; a condenser; a condenser bypass; and a pump upstream of the condenser and condenser bypass and configured to pump fluid generally toward the one or more additional evaporators.

Abstract: A loop heat pipe includes a reservoir, an evaporator adjacent to the reservoir, and a condenser including a condenser inlet and a condenser outlet. The loop heat pipe further includes a vapor transport line connecting the evaporator to the condenser inlet, a liquid transport line connecting the condenser outlet to the evaporator, and a vapor bypass joining the vapor transport line near the condenser inlet and joining the liquid transport line near the condenser outlet. The vapor bypass includes a vapor bypass housing. The vapor bypass housing includes a temperature. The loop heat pipe also includes a thermally-controlled connection between the vapor bypass housing and the condenser, and a thermal controller connected to the thermally-controlled connection and regulating the temperature of the vapor bypass housing via the thermally-controlled connection.

Abstract: A system and method of stabilizing operation of loop heat pipes with a controllable small inner diameter tubing bypassing LHP condenser thereby stabilizing LHP thermal operation by removing thermal-fluid oscillations. Controllability of such condenser bypass stabilizing function, can be achieved by applying a very low auxiliary power (heating or cooling) to the bypass tubing and/or to the liquid return line, without utilizing any moving parts in the LHP system. Moreover, such system with a small gas-loaded heat pipe used as a thermal strap to cool the condenser bypass housing can potentially operate in a completely autonomous manner.
