<p>PURPOSE: To evenly and effectively cool a plurality of long-sized batteries laid in a breadthwise direction with a single rotation drive source. CONSTITUTION: Runners 80a to 80c are laid coaxially on one side of a box body constituting a battery box and the rotation drive shaft 86 of a motor 92 is connected to the runner 80a. Furthermore, the runners 80a to 80c are connected to one another with a connecting means including joints 90a and 90b and the drive shaft 86. When the motor 92 is driven for rotation, all the runners 80a to 80c rotate, thereby feeding the cold air to a plurality of batteries in the battery box forcibly and evenly. As a result, constitution can be simplified and weight can be reduced. Also, economy can be improved, and a maintenance and control work can be easily carried out.</p> |
