This paper presents the experimental investigation of a capillary pumped loop (CPL) to be integrated on a scientific microsatellite. Tests in laboratory have been focused on the thermal behavior of a CPL on a reduced scale, using UHMW (Ultra High Molecular Weight) polyethylene as porous structure and anhydrous ammonia as working fluid. The experimental tests have shown that the proposed CPL presents reliable startups when operating on a heat load range between 20 and 50 W, also presenting very short transients when operating on different heat load profiles. Very fast responses of the CPL have been verified for sudden changes on the heat load applied to the capillary evaporator with reduced superheat. The proposed CPL will be part of a payload to be integrated on a Scientific Microsatellite scheduled to be launch in early 2004.

This paper presents three generically similar impingement liquid coolers that have been engineered for cooling power electronics on future aero gas turbines. The thermal and hydraulic performances of the coolers have been compared with that of a commercial, state-of-the-art pin fin liquid cooler. It is demonstrated that the impingement liquid coolers outperform thermally the baseline pin fin cooler, and with significantly lower pressure drops. The impingement liquid coolers could also be easily modified to trade reduced pressure drop against higher flowrate or reduced thermal performance. A scaling model has also been developed to predict the thermal performances of the coolers for other types of coolants and flow conditions. The model has been applied for predicting the convective thermal performances of the coolers assuming hot aircraft fuel as the coolant. Future work would include an investigation of alternative convective applications in which the cooling system could be systematically explored.
