Research on the Autocontrol Electricdriven Cooling System for Truck

In this paper, the shortage of conventional cooling system of truck is summarized, a new scheme that the cooling fan driven by an electric motor is put forward. The dualfan and whole fanshroud as well as the airstream deflector installation with the motor fan were used in the scheme. The structure and working process of the autocontrol electric cooling fan， the principle of the autocontrol electric cooling system were analyzed. The cooling system can cut down the power loss by 90　%, save the fuel up to 10　% .
