Modeling of heat transfer and thermal regulation for an electric heating glove against a cold environment

Abstract

An electric heating glove can protect the health of workers without affecting flexibility of the hand in a cold environment. A heat transfer model of an electric heating glove with a function of intelligent temperature control was established. The model was verified by a test device for simulating cold-contact exposure. The results showed good agreement between the simulated values and the experimental values. Based on the numerical model, the basic parameters of the electric heating glove were analyzed. It was found that the pressure, thickness and thermal conductivity of the outer fabric were the key factors affecting the thermal regulative performance of the electric heating glove. The power consumption of the electric heating glove was mainly determined by the thickness of the outer fabric. The developed model provides a theoretical basis for the design of an electric heating glove for a thermal regulative effect and energy saving.
