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

Electric heating glove can protect the health of workers without affecting the flexibility of hand in cold environment. A heat transfer model of electric heating glove with a function of intelligent temperature control was established. The model was verified by a test device for simulating the cold-contact exposure. The results showed a 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, the 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 electric heating glove on the thermal regulative effect and energy saving.
