<p><P>PROBLEM TO BE SOLVED: To provide a structure of a cooling or heating device of a battery module which can uniformly cool down or heat a plurality of battery modules arranged in a battery package. <P>SOLUTION: In the cooling or heating device of battery modules, a battery package is composed of battery modules 1 arranged in a holder 3, and air is sent by a fan from one side or both sides of the battery package, and the sent air conducts a heat exchange with each of battery modules. The holder is provided with a plurality of fins which are arranged between the battery modules and which are extruded in a perpendicular direction or an inclined direction to an air flow sent from the fan, and the plurality of fins are formed so that the extruded heights become gradually lower as farther becomes a distance from an air taking side of the battery package to an air discharging side. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
