AIR DUCT FOR ELECTRIC VEHICLE BATTERY COOLING APPARATUS, MAINLY CONCERNED WITH PREVENTING MOISTURE AND DUST OF OUTSIDE AIR FROM MOVING INTO BATTERY TRAY WHILE INCREASING CHARGE CAPACITY OF BATTERIES

摘要

PURPOSE: An air duct for an electric vehicle battery cooling apparatus is provided to prevent moisture and dust of outside air from moving into a battery tray while increasing the charge capacity of batteries contained in the battery tray by uniformly cooling the batteries. CONSTITUTION: An electric vehicle battery cooling apparatus includes a battery tray(200) including a lower tray(220) having an air inlet path and an upper tray(210) having an air discharge path, wherein the battery tray contains a plurality of batteries(400) between the lower tray and the upper tray. The electric vehicle battery cooling apparatus includes an air duct(100) having an inlet(110) opened to the outside of a vehicle, and an outlet(120) communicated with the air inlet path of the lower tray, wherein the inlet faces a front wall surface of the lower tray.
