要約

Figure of merit (FOM) of a two-phase heat transport device such as heat pipe or loop heat pipe (LHP) is a measure of its performance characteristics. In this paper, we propose a method of qualitatively assessing the performance of an LHP by balancing the saturation pressure difference across the LHP capillary wick with the pressure drops in vapour line and condenser. Validation of the proposed method with results of experiments on a mini LHP with working fluids such as acetone, methanol, n-pentane and ethanol shows that the proposed method predicts the operating characteristics of an LHP more accurately and is superior to the other FOM available in the literature for performance assessment.
