Problems solved by technology

However, the radiators of each system work independently and cannot be comprehensively controlled. The arrangement in the engine compartment is relatively complicated and unreasonable. Therefore, the manufacturing cost is high, and the heat dissipation efficiency is low and the energy consumption is high.
