<p>PURPOSE:To improve heat-exchanging efficiency with heat-exchanging fluid even when the outside dimension and shape of a battery are slightly changed by providing deformable heat-exchange bags wherein heat-exchanging fluid passes in the inside between the battery and its housing case. CONSTITUTION:A heat exchanger 7 is composed of plural batteries 1, a housing case 22 having the housing chambers 21 of the batteries 1, and heat-exchanging bags 23 arranged in the middle to pass heat-exchanging fluid. The case 22 is fixed to a vehicle by resin having excellent corrosion resistance or a metal- made vessel. The bag 23 is formed into a bag state of a material excellent in durability, heat-exchanging fluid resistant property and a battery liquid resistant property, and rich in deformability such as a rubber material or a member wherein a fabric material, wherein fiber is woven in the inside of a rubber material, is embedded. The bags 23 in the respective housing chambers 21 are linked with each other by communication parts 24 arranged in the grooves 25 in the case 22, and the heat exchanging fluid flows through the respective bags. The heat-exchanging fluid is closely contacted with the battery 1 and the case 22 due to the internal pressure of the fluid to improve heat-exchanging efficiency.</p> |
