Description

  The present invention relates to vehicles such as electric vehicles and hybrid vehicles.

  Vehicles such as electric vehicles and hybrid vehicles that use a motor as a drive source are equipped with a battery module that supplies electric power to the motor (see, for example, Patent Document 1). This type of vehicle is provided with battery cooling means for maintaining the temperature of the battery within an appropriate range in order to prevent battery performance deterioration due to an abnormal temperature rise.

  For example, a vehicle disclosed in Patent Document 1 is arranged in a battery module housed in a battery case under a cargo compartment, an electric fan arranged on the upstream side of the battery module, and a side trim that covers the wheel house and partitions the cargo compartment.

  In the cooling mechanism configured in this manner, when the cooling fan 117 is driven, air is sucked from the passenger compartment 6 of the vehicle 1 through the intake port (not shown) of the upstream intake duct 118 of the external intake duct 230, and the intake air The air sucked from the opening is supplied as cooling air to the internal intake duct 210 inside the battery unit 100 through the cooling fan 117 and the downstream intake duct 122. The cooling air supplied to the internal intake duct 210 inside the battery unit 100 is sent to the chamber space 116a of the branching portion 116 of the rear internal intake duct 113 and branched from the chamber space 116a, one of which is the front internal intake duct flow The other is sent from the path 116b to the front internal intake duct 111, and the other is sent from the rear internal intake duct flow path 116c to the rear internal intake duct 113.

  The cooling air sent into the front internal intake duct 111 and the rear internal intake duct 113 flows into the cooling flow paths 11b of the front and rear battery modules 11 to cool the battery 11a, and then the inside of the merging duct 112. To reach from both sides and merge again. The cooling air that has reached and merged into the merging duct 112 from the front and back is a lower rigid body 30 positioned below the battery module 11 via a plurality of communication portions 112a formed in the lower part of the merging duct 112 (see FIG. 5). To be discharged.

By leaving the cooling air sub-path 30b in addition to the cooling air main path 30a, the pressure loss of the cooling air on the discharge side can be reduced.

  Subsequently, the cooling air is discharged from the exhaust part 119 formed on the rear side of the case 15 shown in FIG. 2 to the battery storage part 5 outside the case 15 and gradually returned from the battery storage part 5 into the vehicle compartment 6. .
