分析了农用运输车现用冷却风扇驱动方式的缺点后，采用自控电动冷却风扇取代传统的冷却风扇，可使冷却风扇的工作效率提高至78％。驱动方式改进后，发动机可充分利用迎面风的冷却效果，缩短风扇工作时间，从而减少了发动机的功率消耗和散热损失，并可通过控制风扇的工作与否以缩短预热时间，使发动机保持在最佳温度范围内工作。
After analyzing the shortcoming of the current cooling fan drive mode of farm vehicles, the use of self-controlled electric cooling fan to replace the traditional cooling fan can increase the working efficiency of the cooling fan to 78%. Improve the driving mode, the engine can make full use of oncoming cooling effect, shorten the fan working time, thus reducing the engine power consumption and heat loss, and by controlling the fan work to shorten the warm-up time, the engine is maintained at The best temperature range of work.
