Cooling performance and power consumption analysis of automobile engine cooling systemWang, Yong, strojnik ...In order to study the cooling performance of the engine cooling system, as well as investigating the power consumption of the conventional electronic control cooling system with the electronic ... control cooling system with fuzzy controller, the fuzzy controller was designed and corresponding system models were established by using one-dimensional fluid system simulation software Flowmaster and Math software Matlab/Simulink. The analysis of the cooling performance of the engine cooling system was completed to compare the simulation results of two models. The results show that simulation values are close to the experiment values and temperature deviation of the coolant at outlet is less than 1% and the simulation method can be relied on. Heat dissipation rate and pump rotational speed have great influence on the temperature change of the engine coolant. The temperature difference increases from 0°C to 15°C with the heat dissipation rate increases from 5 kW to 45 kW when the rotational speed of the pump and the fan are 2300 r/min and 400 r/min, respectively, and the temperature difference decreases from 15°C to 5°C with the rotational speed of the pump increases from 1400 r/min to 5000 r/min when the rotational speed of the fan and the heat dissipation rate are 700 r/min and 25 kW, respectively. While fan rotational speed hardly affects the temperature change when rotational speed is above 700 r/min. Under NEDC (New European Driving Cycle) condition, compared with the conventional cooling system, the effect of reducing energy consumption by using the cooling system with fuzzy controller is obvious, the energy consumption of the electronic fan and the electronic pump decreases from 227 kJ in conventional electronic control cooling system to 134.8 kJ in electronic control cooling system with fuzzy controller and the energy consumption of the system reduces by 40.6%.Source: Energy sources.
