APPARATUS FOR INDIRECTLY COOLING AND HEATING BATTERY MODULE OF VEHICLE

摘要

apparatus for indirectly cooling and heating a battery module of an eco-friendly vehicle can maximize the heat-radiant performance of a battery, thus preventing volume expansion due to heating. The apparatus includes a thermally and electrically conductive interface plate embedded by overmolding a plurality of heat pipes and electrodes placed between the heat pipes closely between battery cells. A heat sink, that is a condensation part, is integrally connected to an upper end of the heat pipe on an air cooling channel of a battery housing. The apparatus can further improve the battery performance and prevent decreased output of a vehicle by heating the battery to an appropriate temperature under cold starting and low temperature environments.
