Comparison between analytical predictions and experimental data for a loop heat pipe

Abstract

Comparisons between steady-state temperature predictions obtained from a loop heat pipe thermal model, developed by Dynatherm Corporation and modified by the authors, with experimental data obtained from an 800W, titanium wick, loop heat pipe located at the Air Force Research Laboratory (AFRL) thermal facility in Albuquerque, NM are discussed. Model predictions are compared with experimentally determined temperature values for several power levels between 50W and 600W and for condenser temperatures between 233 K and 293 K.
