PROBLEM TO BE SOLVED: To provide a battery cooling air discharge structure which enables reduction of an entire length of an exhaust duct and reduction of costs compared to a case where a battery and a drafter are connected by an exhaust duct.SOLUTION: In a battery cooling air discharge structure 1, battery cooling air which cools a battery 4 disposed below a passenger compartment 3 is discharged from a drafter 7 provided at a vehicle 2 to the outside of the vehicle. The battery cooling air discharge structure 1 includes: a trim space 10 which is formed between a vehicle body side member (a floor panel 11) and an interior member 13, extends along an arrangement direction in which the battery 4 and the drafter 7 are arranged, and communicates with the outside of the vehicle through the drafter 7; and an exhaust duct 20 in which one end is connected with the battery 4 and the other end is connected with the trim space 10 in a position from the battery 4 to the drafter 7.SELECTED DRAWING: Figure 3
【課題】バッテリからドラフタまでの間を排気ダクトによって繋ぐ場合と比べて、排気ダクトの全長を短縮化し、コストを抑制できるバッテリ冷却風の排出構造を提供すること。【解決手段】車室3の下部に配置されたバッテリ4を冷却したバッテリ冷却風を、車両2に設けられたドラフタ7から車外へ排出するバッテリ冷却風の排出構造1において、車体側部材(フロアパネル11)と内装部材13との間に形成され、バッテリ4とドラフタ7との配置方向に沿って延びると共に、ドラフタ7を介して車外に連通するトリム空間10と、バッテリ4に一端を接続し、バッテリ4からドラフタ7までの間の位置でトリム空間10に他端を接続した排気ダクト20と、を備える構成とした。【選択図】図3
