Problems solved by technology

[0003] In the prior art, the engine thermal management simulation only uses a single one-dimensional cooling system simulation to evaluate the pros and cons of thermal management, and only analyzes the parts and parameters included in the cooling system, and cannot realize the system and components associated with the cooling system. The simulation analysis of the actual engine thermal management should not only include the cooling system, but also include multiple systems or components related to it, such as the lubrication system, the engine block, the radiator, and the heater core. Engine thermal management cannot be comprehensively and deeply simulated and analyzed
