Heat transfer enhancement of pcm based heat pipe for thermal energy storage in electronic cooling applications

Abstract

Thermal energy storage plays a major role in a wide verity of industrial and commercial electronic cooling application when there is a mismatch between supply and demand of energy Several promising developments are taking place in the field of thermal energy storage using Phase Change Material PCM in electronic cooling application In the present study a detailed analysis of the thermal performance of a heat pipe of varying heat loads from 10W 50W at the evaporator section was experimentally studied by using acetone as a working fluid In order to study the heat retention time the phase change material OM32 is used as the heat source to the heat pipe at the evaporator The heating and cooling capacities of the PCM are studied with different heat load conditions and the same is compared with water which is also used as one of the heating sources at the evaporator The water cooled condenser is used with different flow conditions from 6 LPH to 10 LPH Experimental studies are carried out on the effect of thermal resistance, heating and cooling capacity with and without PCM evaporative and condenser heat transfer coefficient on the heat load newline
