Study of Inclination Angles on EV Front-end Cooling Module
On the front-end cooling module of electric vehicles (EVs), geometric models of the low-temperature radiator (LTR) with inclination angles of 0°, 15°, 30°, 45°, and 60° were established and numerically simulated. At the same flow rate, the larger the inclination angle, the better the heat transfer o...

| Summary: | On the front-end cooling module of electric vehicles (EVs), geometric models of the low-temperature radiator (LTR) with inclination angles of 0°, 15°, 30°, 45°, and 60° were established and numerically simulated. At the same flow rate, the larger the inclination angle, the better the heat transfer of the LTR, the higher the resistance, and the lower the comprehensive performance, as verified by the test results. By fixing the position of the air-inlet grille, geometric models of the LTR with a shroud at different inclination angles were established for simulation. With an increase in the inclination angle, the shroud resistance decreased; the airflow distribution uniformity and heat transfer performance of the LTR were improved; the resistance increased, and the comprehensive performance decreased. By optimizing the shroud structure, the flow distribution was improved; the flow resistances of the shroud and LTR were reduced, which led to improved heat exchange. It was concluded that the larger the inclination angle, the better the comprehensive performance of the cooling module. Comprehensively considering the arrangement of the front compartment, an inclination angle between 45° and 60° was more applicable. |
