The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] Reference below Figure 1 The vehicle 100 according to an embodiment of the present invention includes: an engine circulation flow path 40, the engine circulation flow path 40 having an exhaust gas discharge branch 41; a first heat exchange medium flow path 10, the first heat exchange medium flow path 10 and the exhaust gas discharge branch 41 cooperate in heat exchange, the first heat exchange medium flow path 10 having a first interface and a second interface, and the first heat exchange medium flow path 10 is provided with a first pump body 11; a heater 12, the heater 12 is provided in the first heat exchange medium flow path 10 to heat the heat exchange medium in the first heat exchange medium flow path 10; a second heat exchange medium flow path 20, the second heat exchange medium flow path 20 having a third interface and a fourth interface; a battery circulation flow path 50, the battery circulation flow path 5 0 and the second heat exchange medium flow path 20 cooperate in heat exchange, the battery circulation flow path 50 has a power battery 51 and a second pump body 52 connected in series, and the battery circulation flow path 50 has a fifth interface and a sixth interface; the air-conditioning circulation flow path 60 and the radiator 13, the air-conditioning circulation flow path 60 and the first heat exchange medium flow path 10 cooperate in heat exchange, the air-conditioning circulation flow path 60 has an air-conditioning flow path inlet and an air-conditioning flow path outlet, the radiator 13 and the first heat exchange medium flow path 10 cooperate in heat exchange, and the radiator 13 is connected to the air-conditioning flow path inlet and the air-conditioning flow path outlet; the connecting regulating valve 80 is connected to the first interface, the second interface, the third interface, the fourth interface, the fifth interface, and the sixth interface.

[0030] Among them, such as Figure 1 As shown, the first interface is interface B, the second interface is interface C, the third interface is interface D, the fourth interface is interface E, the fifth interface is interface F, and the sixth interface is interface G. The connecting regulating valve 80 is connected to the first interface, the second interface, the third interface, the fourth interface, the fifth interface, and the sixth interface. The connecting regulating valve 80 is used to adjust the connectivity relationship between the first interface, the second interface, the third interface, the fourth interface, the fifth interface, and the sixth interface.

[0031] The engine circulation flow path 40 has an exhaust gas emission branch 41, which is used to emit part of the exhaust gas generated by the engine 42. A heat exchange medium can circulate in the first heat exchange medium flow path 10, and the heat exchange medium can be water, oil or other media. The first heat exchange medium flow path 10 and the exhaust gas emission branch 41 cooperate in heat exchange. During the heat exchange process, the heat of the exhaust gas can be absorbed by the heat exchange medium in the first heat exchange medium flow path 10, so as to realize the recovery of the waste heat of the exhaust gas of the engine 42, so as to use the heat of the exhaust gas for other parts of the vehicle 100. For example, the heat of the exhaust gas can be used to heat the passenger compartment, power battery 51 and other parts of the vehicle 100. Such a setting is conducive to improving the energy utilization rate of the engine 42 system, realizing the effective utilization of the exhaust gas thermal energy, and also reducing the exhaust temperature of the exhaust gas, which helps to reduce the thermal pollution of the emissions.

[0032] The first heat exchange medium flow path 10 has a first interface and a second interface. The first heat exchange medium flow path 10 is provided with a first pump body 11. The first pump body 11 can be a pump body of a type such as an intelligent electric water pump or a brushless electric water pump. It is reasonably configured according to actual conditions. The first pump body 11 can promote the circulation of the heat exchange medium in the first heat exchange medium flow path 10 to ensure that the heat exchange medium in the first heat exchange medium flow path 10 can efficiently perform heat exchange. Specifically, when the first interface and the second interface are connected, the first heat exchange medium flow path 10 forms a circulation flow path. The first pump body 11 in the first heat exchange medium flow path 10 can promote the heat exchange medium in the first heat exchange medium flow path 10 to flow from the first interface to the second interface. The heat exchange medium then flows from the second interface to the first interface through the connecting regulating valve 80, thereby achieving efficient circulation of the heat exchange medium in the first heat exchange medium flow path 10, ensuring that the heat exchange medium in the first heat exchange medium flow path 10 can efficiently perform heat exchange with the exhaust gas in the exhaust gas discharge branch 41.

[0033] The heater 12 may be a PTC (positive temperature coefficient thermistor) heater 12, a resistance wire heater 12, or other type of heater 12. This application uses a PTC heater 12 as an example for illustration. The heater 12 is disposed in the first heat exchange medium flow path 10. When the heater 12 is energized, the PTC material within the heater 12 begins to heat up and transfers heat to the heat exchange medium flowing through it, thereby heating the heat exchange medium within the first heat exchange medium flow path 10. This provides a stable heat source for the heat exchange medium within the first heat exchange medium flow path 10, and the PTC heater 12 can automatically adjust the heating power, thereby reducing the energy consumption of the vehicle 100. The second heat exchange medium flow path 20 has a third interface and a fourth interface. The heat exchange medium can flow into the second heat exchange medium flow path 20 from the third interface, and then flow out from the fourth interface after heat exchange, thereby achieving a heat exchange effect.

[0034] The battery circulation flow path 50 and the second heat exchange medium flow path 20 cooperate in heat exchange, enabling heat exchange between the heat exchange medium in the battery circulation flow path 50 and the second heat exchange medium flow path 20 to regulate the temperature of the heat exchange medium in the battery circulation flow path 50. For example, in winter when temperatures are low, heat from the heat exchange medium in the second heat exchange medium flow path 20 can be transferred to the heat exchange medium in the battery circulation flow path 50, thereby heating the power battery 51. The battery circulation flow path 50 has a fifth interface and a sixth interface. The battery circulation flow path 50 includes a power battery 51 and a second pump body 52 connected in series. The power battery 51 can provide electrical energy to the vehicle 100. The second pump body 52 can be a smart electric water pump, a brushless electric water pump, or other types of pump body, and can be appropriately configured according to actual conditions. The second pump body 52 can promote the circulation of the heat exchange medium in the battery circulation flow path 50, ensuring that the heat exchange medium in the battery circulation flow path 50 can efficiently exchange heat. Specifically, when the fifth interface and the sixth interface are connected, the battery circulation flow path 50 forms a circulation flow path, and the second pump body 52 in the battery circulation flow path 50 can promote the heat exchange medium in the battery circulation flow path 50 to flow from the fifth interface to the sixth interface, and the heat exchange medium then flows from the sixth interface to the fifth interface through the connecting regulating valve 80, thereby realizing efficient circulation of the heat exchange medium in the battery circulation flow path 50, so as to ensure that the heat exchange medium in the battery circulation flow path 50 can efficiently exchange heat with the heat exchange medium in the second heat exchange medium flow path 20.

[0035] The heat exchange medium in the air conditioning circulation flow path 60 can be a refrigerant gas. The air conditioning circulation flow path 60 cooperates with the first heat exchange medium flow path 10 in heat exchange. During the heat exchange process, the heat of the gas in the air conditioning circulation flow path 60 can be absorbed by the heat exchange medium in the first heat exchange medium flow path 10. The air conditioning circulation flow path 60 has an air conditioning flow path inlet and an air conditioning flow path outlet. The air conditioning circulation flow path 60 can be provided with a compressor 61. The compressor 61 can compress the refrigerant gas into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the air conditioning circulation flow path 60 and exchanges heat with the first heat exchange medium flow path 10, and then returns to the compressor 61 from the air conditioning flow path inlet to form a cycle.

[0036] Radiator 13 can be a heating, ventilation, and air conditioning system. Radiator 13 works in conjunction with first heat exchange medium flow path 10 to exchange heat. Radiator 13 absorbs heat from the heat exchange medium in first heat exchange medium flow path 10 and transfers the heat to the air in the passenger compartment, thereby increasing the temperature in the passenger compartment. Radiator 13 is connected to the air conditioning flow path inlet and outlet, allowing it to also exchange heat with air conditioning circulation flow path 60. Radiator 13 absorbs heat from the high-temperature, high-pressure gas in air conditioning circulation flow path 60 and transfers the heat to the air in the passenger compartment, thereby increasing the temperature in the passenger compartment.

[0037] Therefore, the vehicle 100 can heat the passenger cabin and the power battery 51 by the heater 12, and can heat the passenger cabin and the power battery 51 by the heat of the heat exchange medium in the air conditioning circulation flow path 60 and the heat of the exhaust gas, so that the passenger cabin and the power battery 51 can be quickly heated, energy saving and emission reduction are facilitated, the overall energy consumption of the vehicle 100 is reduced, and the charging and discharging efficiency and service life of the power battery 51 are improved.

[0038] According to the vehicle 100 of the embodiment of the application, the communication adjusting valve 80 is connected with the first interface, the second interface, the third interface, the fourth interface, the fifth interface and the sixth interface, and is in effective communication with the first interface, the second interface, the third interface, the fourth interface, the fifth interface and the sixth interface, so that the temperature in the passenger cabin can be quickly raised by the waste heat of the exhaust gas of the engine 42, energy saving and emission reduction are facilitated, the overall energy consumption of the vehicle 100 is reduced, the temperature of the power battery 51 can be quickly raised, and the charging and discharging efficiency and service life of the power battery 51 are improved.

[0039] According to some embodiments of the application, the vehicle 100 can further include a controller, a first flow adjusting valve and a second flow adjusting valve, the first flow adjusting valve is arranged in the exhaust gas discharge branch 41, the second flow adjusting valve is arranged in the first heat exchange medium flow path 10, the exhaust gas discharge branch 41 is provided with a first temperature sensor, the first heat exchange medium flow path 10 is provided with a second temperature sensor, the controller is in communication connection with the first flow adjusting valve, the second flow adjusting valve, the first temperature sensor and the second temperature sensor, and the controller controls the first flow adjusting valve and the second flow adjusting valve to work according to the detection information of the first temperature sensor and the detection information of the second temperature sensor.

[0040] The first flow adjusting valve arranged in the exhaust gas discharge branch 41 can adjust the flow of the exhaust gas, by changing the opening degree of the first flow adjusting valve, the flow speed and pressure of the exhaust gas in the exhaust gas discharge branch 41 can be controlled, and then the heat energy transfer capacity of the exhaust gas is changed. The second flow adjusting valve arranged in the first heat exchange medium flow path 10 can adjust the flow of the heat exchange medium in the first heat exchange medium flow path 10, by changing the opening degree of the second flow adjusting valve, the flow speed and temperature of the heat exchange medium in the first heat exchange medium flow path 10 can be controlled, and then the heat exchange efficiency of the first heat exchange medium flow path 10 and the exhaust gas discharge branch 41 is changed.

[0041] The exhaust emission branch 41 is provided with a first temperature sensor capable of monitoring the temperature of the exhaust gas in the exhaust emission branch 41 in real time, and the first heat exchange medium flow path 10 is provided with a second temperature sensor capable of monitoring the temperature of the heat exchange medium in the first heat exchange medium flow path 10 in real time. The controller is in communication connection with the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor, for example: the controller can be in communication connection with the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor through a wire harness, or the controller can be in wireless communication connection with the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor, as long as the controller is in communication connection with the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor.

[0042] The controller controls the first flow regulating valve and the second flow regulating valve according to the detection information of the first temperature sensor and the detection information of the second temperature sensor. Specifically, the controller can calculate and adjust the opening degree of the first flow regulating valve and the second flow regulating valve according to a preset logic or algorithm, so as to dynamically adjust the flow of the exhaust gas and the heat exchange medium, and reduce the risk of boiling of the heat exchange medium in the whole system. In addition, the vehicle 100 can also be provided with an expansion water tank pressure cover capable of automatically adjusting the pressure to maintain the system pressure of the vehicle 100 at 2.5 bar, so as to ensure that the boiling point of the heat exchange medium is higher than the normal working temperature, which not only can optimize the heat exchange efficiency, save energy and reduce emissions, and improve energy efficiency, but also can reduce the risk of boiling of the heat exchange medium, thereby improving the safety and reliability of the vehicle 100.

[0043] According to some embodiments of the present application, as shown in Figure 1 The vehicle 100 can further include: a first heat exchanger 14, the first heat exchanger 14 being formed with a first heat exchange flow path and a second heat exchange flow path, the first heat exchange flow path and the second heat exchange flow path being heat exchange matched, the first heat exchange flow path being configured as part of the exhaust emission branch 41, and the second heat exchange flow path being configured as part of the first heat exchange medium flow path 10.

[0044] The first heat exchanger 14 can be a heat exchanger of a type such as a partition heat exchanger or a counterflow heat exchanger, but the application is not limited thereto, and the first heat exchanger 14 can be reasonably selected and applied according to actual conditions. The application is described by taking the first heat exchanger 14 as a counterflow heat exchanger as an example. In the heat exchange process of the counterflow heat exchanger, heat is transferred from a hot fluid to a cold fluid through a pipe wall, so as to realize the transfer of heat energy, and the cold and hot fluids flow in a counterflow manner, so that the contact time of the cold and hot fluids in the first heat exchanger 14 is longer, the heat transfer is more sufficient, and the heat exchange efficiency can be improved. In addition, the first heat exchanger 14 can be made of a high-temperature-resistant and corrosion-resistant alloy material, so as to ensure that the first heat exchanger 14 can still maintain high performance in harsh environments.

[0045] The first heat exchanger 14 is formed with a first heat exchange flow path and a second heat exchange flow path. The first heat exchange flow path is configured as part of the exhaust gas discharge branch 41, and high-temperature exhaust gas flows in the first heat exchange flow path. The second heat exchange flow path is configured as part of the first heat medium flow path 10, and a heat exchange medium can flow in the second heat exchange flow path. The first heat exchange flow path and the second heat exchange flow path are heat exchange matched, so that the heat exchange medium in the second heat exchange flow path can absorb the heat of the exhaust gas in the first heat exchange flow path, and the heat absorbed by the heat exchange medium can be transmitted to the radiator 13 through the first heat medium flow path 10 and dissipated into the passenger compartment by the radiator 13. The heat of the exhaust gas can be used to heat the passenger compartment, which is beneficial to energy saving and emission reduction and reduces the overall energy consumption of the vehicle 100.

[0046] According to some embodiments of the application, as shown in Figure 1 The vehicle 100 can further include a second heat exchanger 15. The second heat exchanger 15 is formed with a third heat exchange flow path and a fourth heat exchange flow path.

[0047] The second heat exchanger 15 can be a water-cooled heat exchanger, a partition heat exchanger, or the like, but the application is not limited thereto, and the second heat exchanger 15 can be reasonably selected and applied according to actual conditions. The application is described by taking the second heat exchanger 15 as a water-cooled heat exchanger as an example. The second heat exchanger 15 is formed with a third heat exchange flow path and a fourth heat exchange flow path.

[0048] According to some embodiments of the present application, the exhaust emission branch 41 can be provided with an opening and closing valve. By opening or closing the opening and closing valve, the exhaust emission branch 41 can be connected or blocked. Specifically, when the temperature is low in winter, and the heat in the engine 42 exhaust gas needs to be recovered for heating the passenger compartment, power battery 51, etc. of the vehicle 100, the opening and closing valve can be opened to connect the exhaust emission branch 41, realize the heat exchange cooperation between the first heat exchange medium flow path 10 and the exhaust emission branch 41, and then the heat of the exhaust gas can be absorbed by the heat exchange medium in the first heat exchange medium flow path 10, realize the recovery of the exhaust gas waste heat of the engine 42, and use the heat of the exhaust gas to heat the passenger compartment, power battery 51, etc. of the vehicle 100, which is beneficial to improve the energy utilization rate of the engine 42 system, realize the effective utilization of exhaust heat, and also can reduce the exhaust temperature, which helps to reduce the thermal pollution of the emissions. When the temperature is high in summer, there is no need to heat the passenger compartment, power battery 51, etc. of the vehicle 100, at this time, the opening and closing valve can be closed to block the exhaust emission branch 41, the first heat exchange medium flow path 10 and the exhaust emission branch 41 are no longer in heat exchange cooperation, which can reduce unnecessary energy consumption, and then the efficiency of the vehicle 100 can be improved.

[0049] Therefore, the design of the opening and closing valve provides higher flexibility and energy efficiency for the engine 42 system. By flexibly adjusting the state of the opening and closing valve according to the season and the demand of the vehicle 100, the heat in the engine 42 exhaust gas can be recovered and utilized to the maximum extent, while reducing energy consumption and thermal pollution of emissions.

[0052] The third heat exchange medium flow path 30 and the air conditioning circulation flow path 60 are in heat exchange cooperation. Specifically, when the refrigerant in the air conditioning circulation flow path 60 flows, the refrigerant can exchange heat with the heat exchange medium in the third heat exchange medium flow path 30, thereby realizing the heat exchange cooperation between the third heat exchange medium flow path 30 and the air conditioning circulation flow path 60.

[0053] According to some embodiments of the present invention, Figure 1 As shown, the vehicle 100 may further include: a third heat exchanger 31, wherein a fifth heat exchange flow path and a sixth heat exchange flow path are formed in the third heat exchanger 31, the fifth heat exchange flow path and the sixth heat exchange flow path cooperate in heat exchange, the fifth heat exchange flow path is constructed as a part of the third heat exchange medium flow path 30, and the sixth heat exchange flow path is constructed as a part of the air-conditioning circulation flow path 60.

The fifth heat exchange flow path is constructed as a part of the third heat exchange medium flow path 30. Gas can flow in the fifth heat exchange flow path. The sixth heat exchange flow path is constructed as a part of the air-conditioning circulation flow path 60. Low-temperature and low-pressure mist liquid refrigerant can flow in the sixth heat exchange flow path. The fifth heat exchange flow path and the sixth heat exchange flow path cooperate in heat exchange. The low-temperature and low-pressure mist liquid refrigerant absorbs the heat of the gas in the fifth heat exchange flow path through full evaporation, thereby achieving a cooling effect.

When heating the passenger compartment in the winter, the first expansion valve 62 can be short-circuited, allowing the high-temperature, high-pressure gas in the air conditioning circulation circuit 60 to exchange heat with the first heat exchange medium circuit 10.

[0082] In the third functional mode, ML, the control valve 80 is connected to the M and L interfaces, and the motor 74 is connected in series with the intercooler 77. This allows the motor 74 to be kept warm by recovering waste heat from the intercooler 77. Specifically, the intercooler 77 uses a circulating heat exchange medium to cool the high-temperature air compressed by the supercharger.

At this time, the compressor 61 does not work, and the first heat exchange medium flow path 10 is connected to the battery circulation flow path 50, which can heat the passenger compartment and the power battery 51. The heat source can be the heat of the heater 12 and the exhaust gas of the engine 42, and the heat ratio of the passenger compartment and the power battery 51 can be adjusted. When the engine 42 is working, the first heat exchanger 14 can be operated to utilize the heat in the exhaust gas of the engine 42 to heat the passenger compartment and the power battery 51.
