PURPOSE:To prevent a radiator and a condenser both from failing in cooling capacity, by constituting a electric blower so as to be rotated at low speed or stopped when a transmission is shifted to the high speed side, in case of a cooling device bearing the above caption, operated by the electric blower. CONSTITUTION:When a fan switch SW1 is on as well as when a water temperature switch SW2 at the low temperature side is on, if a speed gear is selected to a high speed, a gear detecting switch SW5 is turned on, and the air temperature cooled by an evaporator comes to below the setting one whereby a cooler cold detecting switch SW5 is turned on, an exciting coil 15 of a first relay 5 is energized with current and a normally-closed contact 7 is opened but a normally-opened contact 8 is closed. With these operations, motors 3a and 3b come to be energized via a resistor R2 in consequence, thus rotation of the motor 3a is slowed down. With this constitution, a high speed state and an engine speed state are detected with a simple structure and a blower is controllable, thus a radiator is preventable from failing in cooling capacity. |
