A hybrid capillary and mechanically pumped loop heat pipe (HLHP) includes a fluid loop having an evaporator thermally coupled to a heat load, a condenser thermally coupled to a heat sink, a reservoir, and one or more magnetically levitating pumps configured to pump fluid through the loop thereby improving heat transport capacity and system stability.

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.
