Cooling device for vehicle

Abstract

Abstract PURPOSE:To enable execution of cooling and dehumidification through protection of a battery even during the use of a differential organization, by a method wherein a fan motor rotation reduction circuit is connected in parallel to a fan motor high running speed control circuit, and the control circuit is switched to the reduction circuit for a specified time during operation of a rear window steam-up preventing device. CONSTITUTION:When a defogger 14 for a rear window is turned ON, with a steam-up preventing device's actuation detecting switch 22 closed, an exciting coil 17a of a relay 17 is energized through a transistor 19 to move a contact 17b from a fan motor high running speed control circuit contact (e) to a reduction circuit contact (f). This constitution relieves an electric burden since a fan switch 4 is changed over to the low speed side even it is set to a high speed. Thus, cooling and dehumidification can be executed without worsening the charged state of a battery even during the use of a defogger.
