Abstract:
Motivated with the continuous demand of having efficient cooling techniques to keep up with the incessant development of electronics and consequently the increased rate of their heat generation. The enhancement of the heat transfer rate of water as a prime coolant which is used in many thermal management applications became an area of study of many researchers. The present work experimentally studied the enhancement of heat transfer of a low thermal conductivity coolant (water) interfacing with another high thermal conductivity material, such as liquid metal (Gallium). For a variable volume ratio defined as the ratio of the Gallium volume to the water volume, the rate of cooling heat transfer is observed. Taking place by monitoring the temperature cooling for both coolants to room temperature. The study covers a range of volume ratios from 0 to 4 in steps of 1.0. The results suggested an enhancement of the heat transfer rate directly proportional to the increase of the volume ratio for both, constant water volume and constant Gallium volume.
