Apparatus for cooling high voltage battery

摘要

PURPOSE: A cooling device for high-voltage battery is provided to remarkably reduce the average heating temperature of a high-voltage battery by cooling both surface of the high-voltage battery form differential direction, thereby preventing performance degradation and lifetime reduction due to heating. CONSTITUTION: A cooling device for high-voltage battery comprises a battery case(30) in which a plurality of air passages(31,32) are formed by a plurality of high-voltage batteries being installed; a first intake duct(41) installed to be connected with a part of air path; a second intake duct(42) installed to be connected with residual air path which are not connected with the first intake duct; an exhaust air duct(43) installed to the air path connected to the first intake duct; a second exhaust air duct(44) installed to be connected with the air path connected to the second intake duct(44); and a discharge duct(45) of which one end is connected to the first and the second discharge duct; and a fan(46) installed to the discharge duct.
