Abstract
The common target for vehicles has always been lowest fuel consumption. This paper deals with a new cooling fan for vehicle engine. This fan is used as a wind turbine and generates electric power at high vehicle speed. Also this fan is used as a cooling fan at low speed or when the vehicle needs cooling. The fan can also reduce the vehicle air resistance along with the regeneration of the electric power. We have developed a fan rotor that can operate as cooling fan with the same performance as the current fan and can operate also as a wind turbine at higher performance than the current fan. The effectiveness of this proposal has been confirmed through the wind tunnel tests and CFD calculations.
