A battery module cooling apparatus of the present invention removes a surge tank (10) from an engine room by including the surge tank (10) comprising: a low temperature chamber (11) which moves low temperature cooling fluid to a battery module (1); a high temperature chamber (12) to which high temperature cooling fluid, whose temperature is increased by a heat exchange action performed by passing the battery module (1), returns; a partition (13) which mutually separates the low temperature chamber (11) from the high temperature chamber (12); a low temperature chamber guider (14) which gradually decreases a flow resistance in the flow direction of the low temperature cooling fluid which comes into the low temperature chamber (11); and a high temperature chamber guider (15) which gradually increases the flow resistance in the flow direction of the high temperature cooling fluid which comes into the high temperature chamber (12) and, specifically, resolves all bad influences which are caused by a cooling water line of a narrow diameter by shortening the length of the cooling water line which is connected to the battery module (1) to be almost zero.
