PROBLEM TO BE SOLVED: To provide a secondary battery cooling system that can effectively cool a secondary battery.SOLUTION: According to a secondary battery cooling system, air out of a battery chamber 1 is taken in and heat-exchanged with indoor air by a heat exchanger 16, so that a secondary battery 2 can be cooled by using outdoor air which is generally lower in temperature than air in the battery chamber. When the secondary battery cannot be sufficiently cooled by using only outdoor air, indoor air is cooled by an evaporator 19 of a refrigerant circuit 18, and then the secondary battery is cooled by the indoor air. Therefore, the secondary battery 2 can be also effectively cooled in this case. Furthermore, an evaporator 20 of the refrigerant circuit 18 is also cooled by outdoor air, and thus the efficiency in terms of the refrigerant circuit 18 is enhanced, so that the secondary battery 2 can be effectively cooled. 【課題】本発明は、蓄電池冷却システムに関するもので、蓄電池を効果的冷却することを目的とする。【解決手段】本発明は、電池室１外の空気を取り入れ、熱交換器１６で室内空気と熱交換させるようにしたので、一般的に、電池室内空気よりも低温の室外空気を利用して、蓄電池２を冷却することが出来る。また、室外空気を利用しただけでは、蓄電池２を十分に冷却することが出来ないときには、室内空気を冷媒回路１８の蒸発器１９で冷却後に蓄電池２を冷却することにしたので、この場合でも蓄電池２を効果的に冷却することができる。さらに、冷媒回路１８の凝縮器２０も室外空気によって冷却するので、冷媒回路１８としての効率も高くなり、この結果として、蓄電池２を効果的に冷却することができる。【選択図】図３
