Claims

[Scope of utility model registration request]

In an automotive cooling fan control device that controls the operation of a pair of cooling fans that sequentially valve the condenser and engine cooling water radiator of a refrigeration cycle that are arranged side by side in a spaced-apart state to ventilate cooling air, the engine cooling A water temperature detector for detecting the temperature of water, a condenser cooling state detector for detecting the cooling state of the condenser, and a switch linked to the on/off operation of the refrigeration cycle are provided, and when the refrigeration cycle is turned off, the When the water temperature detected by the water temperature detector reaches a set value or higher, only one of the cooling fans is driven, and when the refrigeration cycle is turned on, both of the cooling fans are driven respectively in conjunction with the switching operation of the switch. At the same time, when the water temperature detected by the water temperature detector and the cooling state detected by the condenser cooling state detector are each lower than the set values, both the cooling fans are driven at a low rotation speed, and the water temperature is Alternatively, the vehicle is characterized in that the number of revolutions of both the cooling fans is variably controlled so that when either one of the cooling states reaches the set value, the number of revolutions of both the cooling fans is driven at a high number of revolutions. cooling fan control device.
