• 【1】 Reduce current loss, minimize harness energy consumption, improve overall system efficiency, and reduce harness heating.
• 【2】 By optimizing the fan structure design and adopting low-noise motors and noise reduction technology, the operating noise has been significantly reduced, thereby improving the quietness of the vehicle interior.
• 【3】 Integrated ECU or dedicated control module, real-time monitoring of engine water temperature, intercooler temperature and other parameters through CAN bus, achieving precise control of fan speed and ensuring that the engine operates within the optimal temperature range.
• 【4】 By using intelligent control to reduce the idle running time of the fan and lower fuel consumption, the tested fuel saving rate can exceed 5%.
• 【5】 After real vehicle reliability testing, no abnormal faults were found
