Provided is a secondary battery module which is maximized in the cooling efficiency of unit batteries by modifying the arrangement structure of the channel of cooling medium and unit batteries. The secondary battery module(10) comprises a plurality of unit batteries(11); a heat transfer body(20) which is provided with a plurality of mounting grooves(21) where the unit batteries are installed, at intervals on the external surface of the heat transfer body for supporting the unit batteries and transfers the heat generated from the unit batteries; and a plurality of channels which is installed at intervals along the inside of the heat transfer body to circulate a cooling medium. The heat transfer body is provided with a plurality of circulation holes(22) for circulating the cooling medium. |
