ABSTRACT

In this paper, different thermal insulation materials including aerogel, PCMs and heat reflect material (HRM) are used to improve the cold protective performance (CPP) of the electrical heating garment (EHG). A heating experiment was designed and conducted to investigate the CPP of different thermal insulation units containing the thermal insulation materials at a low temperature of -20ºC. Results show that the combination of the aerogel and HRM can significantly reduce the equivalen thermal conductivity of the original textile by 24% while keeping the original textile light and flexible. And the thermal insulation unit consisting of the graphene heater, aerogel and HRM treated textile can provide excellent cold protection in extremely cold environment with low supply voltage and proper duty cycle.
