Simulation of Efficiency of Liquid Cooling Garments

Abstract

Liquid cooling garment (LCG) is treated as one kind of effective form-fitting garment applied to remove and release extra heat efficiently from human body whose internal temperature can be easily maintained at a safe dynamic equilibrium level under the severe boundary conditions. In this paper, firstly, two specialized types of liquid cooling garments, wrapped around thermal manikin, are designed as the three-dimensional heat-flux coupling models that are solved numerically using a finite element method, and then the effective cooling temperatures of the thermal manikin skin are proposed as the characteristic parameter to evaluate the cooling effects of these garments. Finally, A comparison of thus effective cooling temperature with the experiment data from the existing reference are shown that this simulation model develops very reliable results for the heat transfer between liquid cooling garments and thermal manikin.
