Operation device of intelligent draught fan control device suitable for vehicle radiating system

The utility model relates to vehicle radiating systems, in particular to an operation device of an intelligent draught fan control device suitable for a vehicle radiating system. According to the technical scheme, the operation device of the intelligent draught fan control device suitable for the vehicle radiating system comprises a relay, a draught fan, an MOS transistor and a delayed reversing circuit. When a coil of the relay is disconnected, the draught fan can rotate forwardly; when the coil of the relay is connected, the draught fan can be electrically connected to the relay so as to rotate reversely; the D electrode of the MOS transistor is electrically connected to the relay, and the MOS transistor enables the relay to be connected when being connected; the delayed reversing circuit is connected with the G electrode of the MOS transistor and is used for controlling the MOS transistor to be connected or disconnected. The operation device of the intelligent draught fan control device suitable for the vehicle radiating system can effectively achieve the forward and reverse rotating operation of the draught fan.
