Active Air Flap과 전동 냉각부품을 이용한 차량열관리

VTMS(Vehicle Thermal Management System) reduces heat loss of internal combustion engine by using active control cooling system. For VTMS control, Some mechanical cooling parts are necessary to change electric cooling parts. Because mechanical cooling parts can not control actively. Changing cooling parts for the active control are electric thermo-stat, electric water pump, electric cooling fan, AAF and etc. Of these Items, AAF is a device which decreases the aerodynamics of the vehicle by changing the shape of the front of the vehicle. It has a significant effect to decrease the aerodynamics of the vehicle. But it reduces cooling effect due to reducing the flow of air which supplied to the radiator. For this reason, VTMS algorithm which control cooling parts includes AAF control algorithm. In this study, AAF, electric water pump and electric thermo-stat are installed at test vehicle to configure the VTMS. And VTMS algorithm which control cooling parts is constructed. It is analyzed to confirm the operation through the experimental results. Also fuel economy improvement is confirmed.
