ABSTRACT:
Disclosed herein is a battery module including a plurality of unit cells stacked one on another. The battery module has a cooling system that accomplishes contact type cooling by a coolant flowing through gaps (flow channels) defined between the unit cells, and the flow channels defined between the unit cells are at a predetermined angle to the flowing direction of the coolant at inlet ports of the flow channels. The contact rate of the coolant to the unit cells in the battery module is increased and a large number of turbulent flows are created by the changing the flow channel through which the coolant flows. Consequently, the occurrence of the velocity gradient of the coolant in the flow channel defined between the unit cells is prevented, and therefore, the cooling efficiency of the battery module is improved.
