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.

Architecture and operational modes of pump-augmented loop heat pipe with multiple evaporators

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.
