摘要：

This paper presents an experimental investigation of a capillary driven two-phase loop; configured on a capillary pumped loop (CPL) mode and designed for the thermal management of up to 50 W. Tests were performed with an internally grooved evaporator with a hollow polyethylene porous structure using acetone and anhydrous ammonia as the working fluids. For-a range of power applied to the evaporator, the system presented reliable start-ups and continuous operation for several hours for each working fluid. As compared to acetone, anhydrous ammonia system showed a better heat transport capability. The capillary evaporator depriming and re-priming was also experimentally investigated. The results showed that the proposed CPL configuration is able to handle the porous structure dryout and promote its rewetting without major external interference. (C) 2003 Elsevier Science Ltd.
