After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0020] This utility model application claims protection for an energy-saving coolant temperature control system, such as... Figure 1 As shown, it includes engine 1, engine ECM 2, electronic thermostat 3, electromagnetic clutch water pump 7, electronically controlled silicone oil fan 8, wiring harness 9, large circulation module 11, and small circulation module 12, wherein:

[0021] The engine ECM2 is fixed to the engine 1 with mounting bolts; the inlet of the electronic thermostat 3 is connected to the outlet of the cylinder head of the engine 1 by bolts; the small circulation outlet of the electronic thermostat 3 is connected to the inlet of the small circulation module 12; the outlet of the small circulation module 12 is connected to the inlet of the electromagnetic clutch water pump 7; the large circulation outlet of the electronic thermostat 3 is connected to the inlet of the large circulation module 11; the outlet of the large circulation module 11 is connected to the inlet of the electromagnetic clutch water pump 7; the electromagnetic clutch water pump 7 is connected to the engine 1. The engine 1 is bolted together; the outlet of the electromagnetic clutch water pump 7 is connected to the cylinder block water inlet of the engine 1 and is bolted together; the electronically controlled silicone oil fan 8 is bolted together with the crankshaft of the engine 1; the wiring harness 9 is fixedly installed on the engine 1 and is used for transmitting current, voltage or control signals; the engine ECM2 is electrically coupled to the electronic thermostat 3, the electromagnetic clutch water pump 7 and the electronically controlled silicone oil fan 8 through the wiring harness 9, and controls the working status of the electronic thermostat 3, the electromagnetic clutch water pump 7 and the electronically controlled silicone oil fan 8 according to the temperature.

[0022] It should be noted that the small circulation module 12 includes a bypass water pipe 10 and an inlet connection pipe 6; the small circulation outlet of the electronic thermostat 3 is connected to the bypass water pipe 10 and bolted together; the outlet of the bypass water pipe 10 is bolted together with the inlet of the inlet connection pipe 6, and is connected to the inlet of the electromagnetic clutch water pump 7 via the inlet connection pipe 6 and bolted together. The bypass water pipe 10 is used to connect the electronic thermostat 3 and the inlet connection pipe 6, and to transmit coolant.

[0023] It should be noted that the large circulation module 11 includes an outlet connection pipe 4, a radiator 5, and an inlet connection pipe 6; the large circulation outlet of the electronic thermostat 3 is connected to the outlet connection pipe 4 and fixed by a clamp; the inlet of the radiator 5 is connected to the outlet connection pipe 4 and fixed by a clamp; the outlet of the radiator 5 is fixed to the inlet connection pipe 6 by a clamp, and is connected to the inlet of the electromagnetic clutch water pump 7 by bolts.

[0024] It should be further explained that the outlet connection pipe 4 is used to connect the electronic thermostat 3 and the radiator 5, and to transmit coolant. The radiator 5 is used to dissipate the heat of the coolant, thereby reducing the coolant temperature. The inlet connection pipe 6 is used to connect the radiator 5, the electromagnetic clutch water pump 7, and the bypass water pipe 10, and to transmit coolant.

[0025] It should be noted that the electronic thermostat 3 is a ball valve driven by a motor. The opening of the ball valve is controlled by the engine ECM2, which in turn controls the flow of coolant to the bypass water pipe 10 or the outlet water connection pipe 4. The target control temperature of the electronic thermostat 3 is 97°C.

[0026] It should be noted that the electromagnetic clutch water pump 7 is used to pressurize the coolant and deliver it to the engine 1; the electromagnetic clutch water pump 7 has two working states: half speed and full speed; at the same speed, the water flow in the half speed state is only half that in the full speed state, and its working state is controlled by the engine ECM2 according to the coolant temperature.

[0027] In this specific embodiment, the half-speed operating temperature of the electromagnetic clutch water pump 7 is 98.5℃, and the full-speed operating temperature is 101.5℃; the electromagnetic clutch water pump 7 is in a half-speed state during the process of rising from 98.5℃ to 101.5℃; the electromagnetic clutch water pump 7 is in a full-speed state during the process of falling from 101.5℃ to 98.5℃.

[0028] It should be noted that the function of the electronically controlled silicone oil fan 8 is to assist the radiator 5 in quickly dissipating heat. The higher the fan speed, the stronger the heat dissipation capacity of the radiator 5. The electronically controlled silicone oil fan 8 is controlled by the engine ECM2, and the fan speed is controlled according to the coolant temperature of the engine 1.

[0029] In this specific embodiment, the initial operating temperature of the electrically controlled silicone oil fan 8 is 102.5°C, and the fully operating temperature is 106°C.

[0030] In this specific embodiment, the module model of the engine ECM2 is CM2670D.

[0031] It should be noted that when this coolant temperature control system is working, the electromagnetic clutch water pump 7 pressurizes the coolant and delivers it to the engine 1; then the coolant enters the electronic thermostat 3 from the engine cylinder head outlet; the electronic thermostat 3 controls the coolant to enter either the small circulation module or the large circulation module according to the coolant temperature; in the small circulation module, the coolant enters the inlet connection pipe 6 from the electronic thermostat 3 through the bypass water pipe 10, and then enters the electromagnetic clutch water pump 7; in the large circulation module, the coolant enters the radiator 5 from the electronic thermostat 3 through the outlet connection pipe 4; the radiator 5 and the electronically controlled silicone oil fan 8 dissipate heat from the coolant, reducing the coolant temperature, and then the coolant enters the inlet connection pipe 6, and finally the inlet connection pipe 6 enters the electromagnetic clutch water pump 7.

[0032] The operating status of each accessory in this coolant temperature control system is controlled by the engine ECM2 based on the water temperature. 97℃ is the target operating temperature for the electronic thermostat 3. During the process of the water temperature rising to 98.5℃, the electromagnetic clutch water pump 7 operates at half speed, and the process from 98.5℃ to 101.5℃ also operates at half speed. When the water temperature exceeds 101.5℃, the engine ECM2 controls the electromagnetic clutch water pump 7 to switch from half speed to full speed. When the water temperature continues to rise to 102.5℃, the electronically controlled silicone oil fan 8 initially turns on, increasing the cooling capacity of the radiator 5. When the water temperature continues to rise to 106℃, the electronically controlled silicone oil fan 8 fully engages, operating at its maximum capacity. Similarly, when the water temperature drops, the only difference from the rise is that during the drop from 101.5℃ to 98.5℃, during which the electromagnetic clutch water pump 7 operates at full speed.
