Abstract:
The present invention relates to an apparatus to indirectly cool a battery module for an eco-friendly vehicle and, more specifically, to an apparatus to indirectly cool a battery module for an eco-friendly vehicle capable of maximizing the performance of a battery heat radiation; and at the same time preventing the battery performance from being deteriorated by indirectly cooling the battery module using an interfacial plate into which a heat pipe is inserted. That is, the present invention provides an apparatus to indirectly cool a battery module for an eco-friendly vehicle in which a thermal conductive interfacial plate into which a heat pipe is inserted into by over-molding the heat pipe, is closely disposed between the battery cells and a heat sink integrally connected to an upper end of the heat pipe as a condenser is placed on an air cooling path, such that adhesion strength between the interfacial plate and the battery cells may be increased and the performance of a battery heat radiation may be maximized, thereby preventing a volume expansion due to the heat radiation. In addition, according to the apparatus to directly cool a battery module for an eco-friendly vehicle, a surface heat radiation member is further disposed between the battery cells in which the interfacial plate is not installed in order to heat the battery at a suitable temperature level in a cold ignition and under low temperature environment, such that the performance of the battery may be improved and the output power of a vehicle may be prevented from being deteriorated.
