Capillary thermal fluid loops
Capillary Thermal Fluid Loops are high conductance thermal links for optimised passive and active cooling of spacecraft heat dissipation payloads. The Capillary Pumped Loop (CPL) is thermally controlled by use of a reservoir. This reservoir is set to a working temperature which will fix the temperature of the thermal payload. It is particularly useful for dissipating payload which needs an accurate temperature control. The CPL possesses an active thermal control of the reservoir.
