The hot end is attached to the surface of the water inlet pipe 11 and the cold end is placed in the atmosphere. It can be understood that when the engine 50 is working, the water inlet pipe The temperature of the surface of the pipeline 11 is greater than the temperature of the atmosphere, that is, there is a temperature difference between the hot end and the cold end of the water inlet pipeline 11, and the first temperature difference power generation patch 21 can convert the temperature difference between the hot end and the cold end into electrical energy based on the thermoelectric effect, generating The electric energy will be transmitted to the energy storage unit 40 through the power transmission line and stored.

The utilization rate of the heat generated avoids the waste of energy, and at the same time can reduce the temperature of the liquid flowing into the engine, which is conducive to lowering the temperature of the engine, thereby avoiding engine damage caused by excessive engine temperature.

Further, continuing to refer to FIG. 1 , the heat control system also includes an electric water pump 70 and an electric temperature control unit 80 . The electric water pump 70 is disposed in the water inlet pipe 11 , and the electric temperature control unit 80 is disposed in the water outlet pipe 12 .

Specifically, the electric temperature control unit 80 includes an in-pipeline temperature sensing subunit and a switch subunit, and both the in-pipeline temperature sensing subunit and the switch subunit are electrically connected to the control unit 30 . The control unit 30 is used to receive the pipeline temperature information sensed by the temperature sensing subunit in the pipeline, and control the conduction state of the switch subunit according to the pipeline temperature information. The switch subunit includes a first conduction state and a second conduction state. In the first conduction state, the engine 50 is conductive to the heat dissipation unit 60, and the engine 50, the heat dissipation unit 60 and the electric water pump 70 form a first cycle. In the second conduction state, the engine 50 and the electric water pump 70 are connected, and the engine 50 and the electric water pump 70 form a second cycle.

Exemplarily, the electric water pump 70 is disposed in the water inlet pipe 11 and is used to pressurize the liquid flowing through the water inlet pipe 11, thereby promoting the liquid to circulate in the water inlet pipe 11, the engine 50, the water outlet pipe 12 and the heat dissipation unit. 60 is continuously circulated to improve the heat dissipation efficiency of the water inlet pipeline 11, the water outlet pipeline 12 and the heat dissipation unit 60.

Exemplarily, the electric temperature control unit 80 is disposed in the water outlet pipe 12. The electric temperature control unit 80 includes a temperature sensing subunit in the pipe and a switch subunit. The temperature sensing subunit in the road is used to sense the water outlet pipe. 12, and transmits the temperature information to the control unit 30. The control unit 30 can control the conduction state of the switch subunit according to the sensed temperature in the water outlet pipeline 12. For example, when the temperature in the water outlet pipeline 12 is greater than the first preset threshold (such as 113°C), the control unit 30 controls the switch subunit to switch to the first conduction state, that is, the switch subunit is fully open. At this time, the liquid can be in Circulation occurs in the engine 50 , the heat dissipation unit 60 and the electric water pump 70 , and the heat of the liquid flowing through the engine 50 can be dissipated into the air through the heat dissipation unit 60 , the water inlet pipe 11 and the water outlet pipe 12 . When the temperature in the water outlet pipe 12 is less than the second preset threshold (such as 93°C), the control unit 30 controls the switch subunit to switch to the second conduction state, that is, the switch subunit is fully closed. At this time, the liquid can be in the engine 50 It circulates with the electric water pump 70 , and the heat of the liquid flowing through the engine 50 can only be dissipated to the air through the water inlet pipe 11 and the water outlet pipe 12 .

It can be understood that when the temperature in the pipeline is low, the control unit 30 needs to control the thermoelectric power generation unit 20 to stop generating electricity, because in this case, the electric energy required by the thermoelectric power generation unit 20 may be greater than the output of the thermoelectric power generation unit 20 to the energy storage unit 40. To avoid the above situation, the control unit 30 can control the starting and stopping of the temperature difference power generation unit 20 according to the temperature in the water outlet pipe 12 sensed by the in-road temperature sensing subunit. For example, when the temperature in the water outlet pipe 12 is greater than the first preset threshold (such as 113°C), that is, when the switch subunit is fully open, the control unit 30 controls the first thermoelectric power generation patch 21 and the second thermoelectric power generation patch 22 The heat in the water inlet pipeline 11 and the water outlet pipeline 12 is converted into electrical energy and stored in the energy storage unit 40 . When the temperature in the water outlet pipe 12 is less than the second preset threshold (such as 93°C), that is, when the switch subunit is fully closed, the control unit 30 controls the first temperature difference power generation patch 21 and the second temperature difference power generation patch 22 to stop generating electricity. . The second preset threshold is smaller than the first preset threshold.

It should be noted that the embodiments of the present invention do not limit the specific values of the first preset threshold and the second preset threshold, and those skilled in the art can set them by themselves according to actual needs.

The position sensing unit 90 is used to sense the position information of the switch subunit. The control unit 30 is electrically connected to the position sensing unit 90 for receiving The location information is used to control the temperature difference power generation unit 20 to generate electricity or to control the temperature difference power generation unit 20 to stop power generation according to the location information.

For example, the position of the switch subunit is related to the temperature in the water outlet pipeline 12. When the temperature in the water outlet pipeline 12 is greater than the first preset threshold (such as 113°C), the switch subunit is fully open. When the temperature in 12 is less than the second preset threshold (such as 93°C), the switch subunit is fully closed, where the second preset threshold is less than the first preset threshold. It should be noted that the embodiments of the present invention do not limit the specific values of the first preset threshold and the second preset threshold, and those skilled in the art can set them by themselves according to actual needs.

Further, the control unit 30 is configured to control the temperature difference power generation unit 20 to generate power or to control the temperature difference power generation unit 20 to stop power generation according to the position information of the switch subunit sensed by the position sensing unit 90 . For example, when the position sensing unit 90 senses that the switch subunit of the electric thermostat unit 80 is fully open, the control unit 30 controls the temperature difference power generation unit 20 to convert the heat in the connecting pipe 10 into electrical energy and store it in the energy storage unit. 40, when the position sensing unit 90 senses that the switch subunit of the electric temperature control unit 80 is fully closed, the control unit 30 controls the temperature difference power generation unit 20 to stop generating electricity.

For example, when the temperature in the water outlet pipeline 12 is lower than the first preset When the temperature (such as 80°C) and the vehicle's driving speed are greater than the preset speed (such as 60km/h), it means that the hybrid vehicle in this implementation needs to start the engine 50. At this time, the control unit 30 will control the energy storage unit 40 to discharge. The resistor patch 100 converts the electric energy released by the energy storage unit 40 into heat energy and then heats the engine 50 . The engine 50 is heated by the resistor patch 100 , thereby reducing fuel consumption during engine starting. When the temperature in the water outlet pipe 12 is greater than the second preset temperature (such as 85°C), it means that the engine 50 has been successfully started and is running stably, and the resistor patch 100 is no longer needed to heat the engine 50. At this time, the control unit 30 will control the energy storage unit 40 to stop discharging.
