AI Technical Summary
The existing engine cooling system lacks pressure regulation and control functions, resulting in constant cooling system resistance and flow rate, making it impossible to accurately control engine cooling and affecting engine performance.
The design includes a coolant circuit, first and second regulating valves, and a controller. The flow rate and pressure of the coolant are controlled by adjusting the opening of the regulating valves. Combined with inlet and outlet water temperature and pressure sensors, precise control of the cooling system is achieved.
The performance of the engine water pump has been improved, ensuring system flow, controlling the temperature difference between the engine inlet and outlet water within a preset range, improving the heat exchange efficiency of the cooling system, ensuring sufficient water flow and reasonable flow rate for each engine component, and achieving efficient cooling.
