The problem of dissipating high waste heat fluxes in electronic components has been studied extensively in recent years. Common applications include VLSI circuits, power electronics and high-powered laser, x-ray and cathode-ray tube systems. In spacecraft, the problem becomes more challenging due to the relatively poor heat sink environment available. This paper describes design, development and test of a pumped heat pipe coldplate, with emphasis on measured performance. The device is designed to integrate high-flux, detachable spacecraft payloads to a pumped thermal control loop. The component evaporates ammonia working luid to remove waste heat from a payload, and control of the evaporation and phase separation is accomplished using the Self-Regulating Capillary Fluid Management (SRCFM) concept. This concept also makes the device performance insensitive to gravity.
