DEVICE FOR INDIRECTLY COOLING BATTERY MODULE OF ECO-FRIENDLY VEHICLE

摘要

A device for indirectly cooling a battery module of an eco-friendly vehicle is provided that cools the battery module using an interfacial plate into which a heat pipe is inserted to maximize battery heat emission performance and simultaneously prevent degradation of battery performance. A thermally-conductive interfacial plate in which a heat pipe is embedded by over-molding is disposed between battery cells and a heat sink, which is a condensation unit, integrally connected to an upper end of the heat pipe is disposed in a cooling air flow path to improve contact strength between the interfacial plate and the battery cells. A planar heat emitter is disposed between the battery cells where the interfacial plate is not disposed to heat the battery to a proper-level temperature in a cold-start environment and a low-temperature environment, thereby improving battery performance and preventing degradation in vehicle power.

1. A device for indirectly cooling a battery module of an eco-friendly vehicle, comprising:
a thermally-conductive interfacial plate in which over-molded heat pipes are embedded, the thermally-conductive interfacial plate disposed between at least two battery cells; and a heat sink integrally connected to an upper end portion of each over-molded heat pipe, the heat sink disposed in a cooling air flow path.
