Study on Heat Transfer Performance of Antifreeze-R134a Heat Exchanger (ARHEx)

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...

A heat transfer formula for the antifreeze side in the ARHEx was obtained by means of the coefficient of Nusselt number with experimental analysis. The performance of heat transfer and pressure drop for the refrigerant side of the ARHEx was deduced for the given condition.https://www.mdpi.com/1996-1073/13/22/6129avionicsAntifreeze-R134a heat exchangerheat transfer performancethermal management
