摘要：
To enhance the efficiency of vehicle cooling system, firstly the matrix fan configuration is introduced into the traditional car cooling system, and based on which a fuzzy controller is designed. Then a co-simulation is conducted to study the effects of matrix fans with fuzzy controller on the performance of vehicle cooling system. The results indicate that under transient condition, the adoption of matrix fans with fuzzy controller can reduce the fluctuation amplitude of outlet temperature by around 76% and lower the energy consumption of fan system by 31.2%. Under the multi-mode operation of matrix fan, fuzzy controller can not only adjust the rotation speed of matrix fan according to feedback information, but also change the number of working fans with minimum energy consumption as objective, hence achieving better capability in tracking target temperature and lower energy consumption. Compared with single mode operation, the multi-mode operation has a 30.5% smaller dynamic error of temperature and an 18.8% less power consumption of fan on average. © 2020, Society of Automotive Engineers of China.
