Abstract
The advanced control heat transfer loop apparatus (1) for heat transfer and thermal control applications uses a two-phase fluid as a working media and comprises at least one evaporator (2) to be connected with a heat source and comprising primary capillary pump (4), a thermal stabilization-compensation chamber (3) being attached to the at least one evaporator (2), at least one condenser (24) to be connected with a heat sink, liquid lines (22) and vapor lines (23) connecting the at least one evaporator (2) and the at least one condenser (24), a remote compensation chamber (20), temperature sensors (27) for detecting the temperature of the remote compensation chamber (20) and at the thermal stabilization compensation chamber (3) attached to the at least one evaporator (2), at least one heating element (19) for heating the remote compensation chamber (20), and a controller (28). The controller (28) is configured to monitor the temperatures detected by the sensors (27) and to control the heating element (19) in such a way that the value of the difference ΔTControl between the temperature of the remote compensation chamber (20) and the temperature of the thermal stabilization-compensation chamber (3) attached to the at least one evaporator (2) is positive.
