Characteristic and Affection Analysis on Air into the Cabin Process Based on Wind Tunnel

Abstract:

The wind tunnel test dating for the cooling module in the vehicle conditions shows that the actual fan rotation is evidently different from the fan in bench test rotation. There is an intake high pressure zone. It is easy to conduct airflow into the cabin, and under the cabin, there is a negative pressure zone. It is easy to conduct airflow outside the cabin. Both of the different pressure zones affect the fan rotation. Air path of the cabin is divided into three different areas. Base on the parameters of CP BIR and-CP, the aerodynamic characteristics of the cabin build the cooling module under the vehicle working conditions. The model can predict the states of the fan working, when the target vehicle speed conditions are met, and it has important application value for the design of intelligent cooling module control system as well.
