Pump, And Earth-Testable Spacecraft Capillary Heat Transport Loop Using Augmentation Pump And Check Valves
Pump, And Earth-Testable Spacecraft Capillary Heat Transport Loop Using Augmentation Pump And Check Valves
US Patent:
5816313, Oct 6, 1998
Filed:
Feb 25, 1994
Appl. No.:
8/201733
Inventors:
David Baker - Hamilton Square NJ
Assignee:
Lockheed Martin Corporation - Sunnyvale CA
International Classification:
F28F 2700
US Classification:
165 41
Abstract:
A spacecraft includes heat-generating payload equipment, and a heat transport system with a cold plate thermally coupled to the equipment and a capillary-wick evaporator, for evaporating coolant liquid to cool the equipment. The coolant vapor is coupled to a condenser and in a loop back to the evaporator. A heated coolant reservoir is coupled to the loop for pressure control. If the wick is not wetted, heat transfer will not begin or continue. A pair of check valves are coupled in the loop, and the heater is cycled for augmentation pumping of coolant to and from the reservoir. This augmentation pumping, in conjunction with the check valves, wets the wick. The wick liquid storage capacity allows the augmentation pump to provide continuous pulsed liquid flow to assure continuous vapor transport and a continuously operating heat transport system. The check valves are of the ball type to assure maximum reliability. However, any type of check valve can be used, including designs which are preloaded in the closed position.
