摘要： The present invention relates to a battery module comprising: a plurality of battery cells disposed to overlap each other in a thickness direction thereof; a battery case configured to accommodate the battery cells and having a structure of which a lower portion is opened; and a heat dissipation member comprising a cover plate coupled to the lower portion of the battery case to support the battery cell and a heat dissipation body provided on one surface of the cover plate, on which the battery cell is supported, to dissipate heat generated in the battery cell, wherein the heat dissipation body comprises a first heat transfer material provided to be connected to a center of one surface of the cover plate in a longitudinal direction of the battery cell and a second heat transfer material provided on both portions of the first heat transfer material and having a structure aligned in a plurality of rows in the longitudinal direction of the battery cell, and the second heat transfer materials are aligned so that an interval therebetween is gradually narrowed from a center toward both ends of the battery cell to gradually improve heat dissipation performance from the center toward both the ends of the 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.
