Study on Heat Transfer Performance of Antifreeze-R134a Heat Exchanger (ARHEx)
In this paper, the liquid cooling and vapor compression refrigeration system based on an Antifreeze-R134a Heat Exchanger (ARHEx) was applied to the thermal management system for high-power avionics in helicopters. The heat transfer performance of the ARHEx was studied. An experimental prototype of A...
