Claim:
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; and a planar heat emitter disposed between battery cells where the interfacial plate is not disposed; wherein the planar heat emitter includes; a film in which a polyurethane layer for surface-contact with a battery cell and a polyethylene terephthalate (PET) layer for heat resistance in heat emission are laminated to each other; a heat emitter on the PET layer of the film; and a protection layer of liquid silane resin (LSR) coated and surface-hardened on the heat emitter to protect the heat emitter.
