Problems solved by technology

[0006] However, if the spare tire is not stored above the power supply unit, and the floor height of the luggage room and the cabin is restricted to be low to ensure a large space for the luggage room and the cabin, it is difficult to adopt the above structure, and there is room for improvement.
That is, in the cooling structure of the vehicle power supply unit described in Patent Document 1, the floor height of the luggage room and the cabin cannot be restricted to be low due to the interference of the air supply duct.

Embodiment Construction

[0064] Hereinafter, an embodiment of the present invention will be described based on the drawings. In addition, the drawings are viewed according to the orientation of the reference numerals.

[0065] Such as Figure 1 ~ Figure 4 As shown, the vehicle battery cooling structure of this embodiment includes: a battery 12 arranged under the floor of the luggage room 11 behind the rear seat 10, and the battery 12 is housed in a waterproof case 13; 15, which has an air inlet 14, one end of the downstream side of the air inlet duct 15 is connected to the waterproof housing 13, and the air inlet duct 15 supplies the air introduced from the air inlet 14 as cooling air to the battery 12; and The air duct 16 is connected to the waterproof casing 13 at one end of the upstream side, and the exhaust duct 16 discharges the cooling air that has cooled the battery 12 from the waterproof casing 13. In addition, the symbol F indicates the floor surface of the luggage room 11.

Abstract

The invention provides a cooling mechanism of a vehicle battery, which can inhibit pressure loss caused by air supply and can ensure a spacious space. An air inlet pipeline (15) comprises a first pipeline component (20), at least a part of which is disposed under a floor, an upstream side second pipeline component (21) and a downstream side second pipeline component (22), which are disposed at a position other than below the floor. A connection part (45) of the first pipeline component (20) and the downstream side second pipeline component (22) is disposed at a position other than below the floor.

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 electric vehicles and hybrid vehicles, for example, a battery as a driving energy source for an electric motor is mounted under the floor of a luggage space. A battery is a heat-generating component that generates heat during charging and discharging, and therefore needs to be cooled to maintain battery performance. A solution for cooling using cooling air introduced from the interior of the vehicle or the like has been studied (for example, refer to Patent Document 1). [0003] The cooling structure of the power supply unit for a vehicle described in Patent Document 1 uses a cooling fan to introduce air in the vehicle cabin from an air inlet provided near the rear seat, and supplies the air as cooling air to the power supply unit containing the battery Cool down. Use the tire tray for the sp...
