車両用バッテリユニット
Document Type and Number:
Japanese Patent JP5528993
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make a noise which a cooling fan emits hard to be transferred to a cabin, while securing cooling performance of a battery of a battery unit.SOLUTION: The battery is cooled with refrigerant which flows in a cooling duct, while the refrigerant inhaled from an inlet is passing a cooling duct, an exhaust duct 76 and the cooling fan 72 and ejecting from an outlet 73b. Since the exhaust duct 76 is arranged between a floor panel 67 and the cooling fan 72 of the cabin, the noise is made hard to be transferred to the cabin by intercepting the noise generated by the cooling fan 72 with the exhaust duct 76 and the floor panel 67 and silence can be raised. Since an axis line of an inlet 27a of the cooling duct which opens to a vehicle body rear face and an axis line of the outlet 73b of the cooling fan 72 which opens to the vehicle body rear face shifts in a planar view, and the temperature increased refrigerant after heat exchange ejected from the outlet 73b makes it hard to be directly inhaled by a cooling duct from the inlet 27a, and the cooling effect of the battery can be heightened.
