DESIGN OF LAMINATED HEATING MODULE FOR ELECTRIC VEHICLES

Abstract

Recently, to save energy in electric vehicles, there has been a need to develop radiant heating modules to increase the efficiency of vehicle heating systems. In this study, effect of insulation and covering material's properties (thermal conductivity, emissivity, density, and specific heat) on the efficiency of the heating module, was investigated using finite element analysis. The radiant heating module were composed of a covering material, a heating film, an insulation material, and an injection substrate. Leather, cloth, and suede were used as covering material, and honeycomb made of nylon, polyurethane foam, and melamine foam were used as heat insulation materials. ABAQUS joule heating simulation was used to calculate the front temperature, heat flux of the heating module, and heat receiving unit temperature. As a result, the heating module with the melamine foam insulating layer and suede for the covering material has the highest efficiency compared to the other cases.
