摘要： The present invention relates to a battery pack in which a refrigerant inlet port and a refrigerant outlet port are formed at an upper portion and a lower portion of a pack case, and a refrigerant inlet unit and a refrigerant outlet unit are formed in the pack case. The refrigerant inlet unit includes: (a) a parallel inlet portion which contacts the refrigerant inlet port and which is parallel to an upper surface of a unit cell stack; and (b) an inclined inlet portion which is connected to the parallel inlet portion such that the spacing from the upper surface of the unit cell stack becomes narrower from the refrigerant inlet port to an opposite end facing the refrigerant inlet port. An inflection point, at which the parallel inlet portion and the inclined inlet portion meet each other, is located in an area of a refrigerant flow channel ("first refrigerant flow channel") between a first unit cell ("first cell") in the direction of the refrigerant inlet port and the case facing the first cell.

摘要： The present invention relates to a battery pack comprising a rechargeable/dischargeable battery cell or unit modules ('unit cells'). The battery pack comprises: a battery module group including one or more battery modules in which said unit cells are spaced apart from each other by a spacing for flow of a refrigerant and embedded within a pack case in the widthwise direction (transverse direction) of the battery pack such that the unit cells stand upright; refrigerant inlet units formed sequentially in the space between a lower surface of the pack case and battery modules; a refrigerant outlet unit formed in the space between an upper surface of the pack case and the battery module group; an electrical component located at one side surface of the battery module group and mounted in an internal space formed by the refrigerant outlet unit; and a refrigerant flow channel having a structure in that the refrigerant introduced through a refrigerant inlet port passes through each unit cell to cool the unit cells, and a portion of the refrigerant passed through the unit cells flows in a vortex flow to cool the electrical component and is discharged through a refrigerant outlet port.
