  • Patent number: 9509023
    Abstract: When a battery is supported on a cooling plate, since a heat transfer sheet, which is deformable by pressure, is held between the cooling plate and a cooling surface of the battery, it is possible to efficiently transfer the heat of the battery from the cooling surface to the cooling plate via the heat transfer sheet, thereby enhancing the effect in cooling the battery. Since the heat transfer sheet includes a plurality of through holes, compared with a case in which a heat transfer sheet does not include the through hole, the reaction force generated by restoration of the compressively deformed heat transfer sheet to its original shape is decreased, thus reducing the load acting on a mounting flange securing the battery to the cooling plate and thereby preventing the mounting flange from being broken.
