Cooling structure of battery used for vehicle

Abstract

The present invention provides a cooling structure of a battery used for a vehicle. The cooling structure has a foreign material containing part capable of containing foreign materials falling into an air-intake pipeline, and can ensure spacious space of a baggage room and a cabin. For an air-intake pipeline (15) extending from the floor to a side wall surface (23) separating out a baggage room (11) or a cabin, a foreign material containing part (30) is arranged at a branch of a flow passage (22b) for cooling air, the foreign material containing part (30) is used for containing the foreign materials falling from an air inlet (14). The foreign material containing part (30) is arranged in the side wall surface (23) and arranged at a position closer to an inner side than the flow passage (22b) in a vehicle width direction, a part of the air-intake pipeline (15) is arranged below the foreign material containing part (30).

Description

technical field [0001] The present invention relates to a cooling structure suitable for batteries in vehicles such as electric vehicles and hybrid vehicles. Background technique [0002] In an electric vehicle and a hybrid vehicle, for example, a battery as a driving energy source for an electric motor is mounted under the floor of the luggage space. The battery is a heat-generating component that generates heat during charge and discharge, and therefore needs to be cooled to maintain battery performance, and a method of cooling by cooling air introduced from the interior of a passenger compartment or the like has been studied (for example, refer to Patent Document 1). [0003] The cooling structure of the vehicle power supply unit described in Patent Document 1 is such that air in the passenger compartment is drawn from an air intake provided near the rear seat by a cooling fan, and the air is supplied as cooling air to a power supply unit including a battery Cool down. ...

AI Technical Summary

Problems solved by technology

[0005] However, if there is an air intake duct that introduces air into the vehicle compartment from the air intake port, there is a possibility that conductive foreign objects such as rings may fall into the air supply duct from the air intake port inadvertently, and the conductive foreign matter may fall into the power supply. On the unit side, it may short-circuit the battery

In the cooling structure of a power supply unit for a vehicle described in Patent Document 1, there is no description regarding foreign matter falling into the air supply duct.
