摘要： A battery pack includes a battery cell stack formed by a plurality of stacked battery cells, a battery module housing configured to wrap the other outer surfaces of the battery cell stack excluding a first surface and a second surface, from which electrode leads protrude, a water tank configured to supply a coolant to the battery cell or the battery module housing, and a battery pack case configured to receive a plurality of battery module housings. The battery pack case includes a pack case space portion located adjacent to the first surface and a crossbeam located adjacent to the second surface, whereby, when fire breaks out in the battery cell, it is possible to rapidly and accurately prevent spread of flames of the ignited battery cell.

摘要： The present invention provides a heatsink, which is coupled to a pack tray, on which a plurality of secondary batteries are mounted, and comprises an inlet and an outlet so that cooling water is introduced into and discharged from a chamber therein, the heatsink comprising: a dimple convexly protruding to the inside of the chamber to form a flow path of the cooling water, wherein the dimple is provided in plurality, and the plurality of dimples are spaced apart from each other, wherein the dimples are disposed so that a gap between the dimples adjacent to each other in a specific area and a gap between the dimples adjacent to each other in the other area are different from each other.
In the present invention having the above-described constituents, the gap between the dimples may vary to prevent deformation and bending in the specific direction.
