Abstract:

A Loop Heat Pipe LHP is a passive two-phase heat transfer device developed and successfully employed to cool spacecraft satellite electronics. The intrinsic benefits of this technology lightweight, small volume high thermal conductance make it an attractive potential solution to many problems in ground vehicle thermal management. As most published LHP research has focused on cooling orbiting spacecraft components there is little knowledge of how LHPs perform under the temperature extremes -40 deg C to 40 deg C and diurnalseasonal fluctuations anticipated with terrestrial applications. Ambient temperature extremes mandate consideration of transport line heat exchange with the surroundings parasitic lossesgains.
