<P>PROBLEM TO BE SOLVED: To provide a battery cooling device of an elevator control panel capable of installing a battery of the elevator control panel with a simple constitution without requiring many components such as a temperature sensor and a fan. <P>SOLUTION: In Fig. 1, drain water generated when using a cooling device 2 in a car 1 is temporarily stored in a drain water tank 3. An elevator control panel 4 is moved to the position from which drain water in the car can be discharged. The elevator control panel operates a first duct 5 stored therein to a water-dischargeable position, a water discharging valve 6 is opened, and the drain water is allowed to flow from the drain water tank to a cooling tank 8. The battery is cooled by performing the heat exchange between a battery 9 installed on the back side of the cooling tank in the elevator control panel and the drain water. <P>COPYRIGHT: (C)2009,JPO&INPIT |
