Hybrid Two-Phase Mechanical / Capillary Pumped Loop for High-Capacity Heat Transport 2007-01-3198

Like other spacecraft subsystems, the thermal control system had to comply with the following requirements: (i) robust/reliable in harsh environments, (ii) minimal power consumption, (iii) compact/lightweight, and (iv) long life even without maintenance. For this reason, passive two-phase heat transport technologies such as heat pipes, Loop Heat Pipes, and Capillary Pumped Loops became popular among spacecraft engineers. Future thermal requirements may outgrow the capabilities of the existing devices. The US Naval Research Laboratory is leading a research and development effort to produce advanced technologies for the thermal management of the Navyapos;s next-generation spacecraft and satellites.
