Under transient conditions, the opening of the car's active grille system(AGS) and the rotational speed of the fan are adjusted in realtime, leading to continuous changes in the air intake volume of the heat exchanger. Consequently, the fan of the thermal management test bench cannot provide accurate and immediate transient air supply for the heat exchanger. In this paper, computational fluid dynamics (CFD) simulation technology is used to analyze the relationship between the inlet air volume of the heat exchanger and factors such as vehicle speed, AGS opening and fan speed. Subsequently, a mathematical model is constructed with a prediction error of less than 6.6%. The model is then integrated into the CANOE device, connected to the VN1640 device and the fan system. The system can collect realtime CAN signals for vehicle speed, AGS opening, and fan speed, calculate the inlet air volume of the heat exchanger, and control the corresponding air volume output from the fan. It achieves the goal of providing the heat exchanger with accurate and realtime air supply through the bench fans.
