COOLING MEMBER HAVING IMPROVED COOLING EFFICIENCY, AND BATTERY MODULE INCLUDING SAME

WIPO Patent Application WO/2012/115351

A2

The present invention relates to a cooling member having improved cooling efficiency which is to be mounted above and/or under a battery module or battery pack in order to remove heat generated from battery cells during charging and discharging. The cooling member includes: a thermally conductive medium including terraced coupling plates, the lengths of which are mutually different, wherein a refrigerant passage is defined between the interfaces of the coupling plates; and a refrigerant pipe having a hollow structure through which refrigerant flows, the refrigerant pipe including a main pipe and at least one branch pipe vertically extending when the branch pipe is in communication with the main pipe, so as to communicate with the refrigerant passage of the thermally conductive medium. In one end of the refrigerant passage of the thermally conductive medium, a mounting groove having a shape corresponding to that of an outer surface of the branch pipe is defined in the plate, from among the plurality coupling plates, which has a relatively long length, and an auxiliary plate surrounding the outer surface of the branch pipe is mounted when the branch pipe is mounted on the mounting groove.
