The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0029] Reference below Figure 1 The vehicle 100 according to the embodiment of the present invention includes: an engine circulation flow path 40, the engine circulation flow path 40 has an exhaust gas emission branch 41; a first heat exchange medium flow path 10, the first heat exchange medium flow path 10 and the exhaust gas emission branch 41 cooperate in heat exchange, the first heat exchange medium flow path 10 has 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 has 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, 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, 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 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, and the exhaust gas emission branch 41 is used to emit part of the exhaust gas generated by the engine 42. A heat exchange medium can be circulated in the first heat exchange medium flow path 10, and the heat exchange medium can be water, oil and 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 can also reduce 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 set 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, so as to realize the efficient circulation of the heat exchange medium in the first heat exchange medium flow path 10, so as to ensure 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 types of heaters 12. This application takes the heater 12 as an example for explanation. The heater 12 is arranged in the first heat exchange medium flow path 10. When the heater 12 is powered on, the PTC material inside the heater 12 starts to heat up and transfers the heat to the heat exchange medium flowing through it to heat the heat exchange medium in the first heat exchange medium flow path 10. It can provide a stable heat source for the heat exchange medium in 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 the heat exchange medium flows 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, and can realize heat exchange between the heat exchange medium in the battery circulation flow path 50 and the heat exchange medium in the second heat exchange medium flow path 20, so as to adjust the temperature of the heat exchange medium in the battery circulation flow path 50. For example, when the temperature is low in winter, the heat of 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 has a power battery 51 and a second pump body 52 connected in series. The power battery 51 can provide electric energy for the vehicle 100. The second pump body 52 can be a pump body of a type such as an intelligent electric water pump or a brushless electric water pump. It is reasonably set 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 to ensure that the heat exchange medium in the battery circulation flow path 50 can efficiently perform heat exchange. 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 may be a refrigerant gas. The air conditioning circulation flow path 60 and the first heat exchange medium flow path 10 cooperate 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 may 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 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] The radiator 13 can be a HVAC, and the radiator 13 and the first heat exchange medium flow path 10 are heat exchanged together. The radiator 13 can absorb the heat of the heat exchange medium in the first heat exchange medium flow path 10, and transfer the heat to the air in the passenger compartment, thereby increasing the temperature in the passenger compartment. The radiator 13 is connected to the air conditioning flow path inlet and the air conditioning flow path outlet, so that the radiator 13 can also perform heat exchange with the air conditioning circulation flow path 60. The radiator 13 can absorb the heat of the high-temperature and high-pressure gas in the air conditioning circulation flow path 60 and transfer the heat to the air in the passenger compartment, thereby increasing the temperature in the passenger compartment.
[0037] Therefore, the vehicle 100 of the present application can heat the passenger compartment and the power battery 51 through the heater 12, and can also heat the passenger compartment and the power battery 51 through the heat of the heat exchange medium in the air-conditioning circulation flow path 60 and the heat of the exhaust gas. It can not only quickly heat the passenger compartment and the power battery 51, but also is beneficial to energy conservation and emission reduction and reduce the overall energy consumption of the vehicle 100, and improve the charging and discharging efficiency and service life of the power battery 51.
[0038] According to the vehicle 100 of the embodiment of the present invention, 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, and the connecting regulating valve 80 is effectively distributed and connected with the first interface, the second interface, the third interface, the fourth interface, the fifth interface, and the sixth interface. The waste heat of the exhaust of the engine 42 can be used to quickly increase the temperature in the passenger compartment, which is beneficial to energy conservation and emission reduction and reducing the overall energy consumption of the vehicle 100. It can also quickly increase the temperature of the power battery 51 and improve the charging and discharging efficiency and service life of the power battery 51.
[0039] According to some embodiments of the present invention, the vehicle 100 may further include: a controller, a first flow regulating valve and a second flow regulating valve, the first flow regulating valve being arranged in the exhaust gas emission branch 41, the second flow regulating valve being arranged in the first heat exchange medium flow path 10, the exhaust gas emission branch 41 being provided with a first temperature sensor, the first heat exchange medium flow path 10 being provided with a second temperature sensor, the controller being communicatively connected with the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor, and the controller controlling the operation of 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.
[0040] Among them, the first flow regulating valve is arranged in the exhaust gas discharge branch 41 to regulate the flow of the exhaust gas. By changing the opening of the first flow regulating valve, the flow velocity and pressure of the exhaust gas in the exhaust gas discharge branch 41 can be controlled, thereby changing the heat energy transfer capacity of the exhaust gas. The second flow regulating valve is arranged in the first heat exchange medium flow path 10 to regulate the flow of the heat exchange medium in the first heat exchange medium flow path 10. By changing the opening of the second flow regulating valve, the flow velocity and temperature of the heat exchange medium in the first heat exchange medium flow path 10 can be controlled, thereby changing the heat exchange efficiency between the first heat exchange medium flow path 10 and the exhaust gas discharge branch 41.
[0041] The exhaust gas emission branch 41 is provided with a first temperature sensor, which can monitor the temperature of the exhaust gas in the exhaust gas emission branch 41 in real time. The first heat exchange medium flow path 10 is provided with a second temperature sensor, which can monitor the temperature of the heat exchange medium in the first heat exchange medium flow path 10 in real time. The controller is connected to the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor in communication. For example, the controller can be connected to the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor through a wiring harness, or the controller can be connected to the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor through wireless communication. As long as the controller is connected to the first flow regulating valve, the second flow regulating valve, the first temperature sensor and the second temperature sensor in communication, it will be sufficient.
[0042] The controller controls the operation of 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 of the first flow regulating valve and the second flow regulating valve according to the preset logic or algorithm, so as to flexibly and 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 kettle pressure cap, which can automatically adjust the pressure to maintain the system pressure of the vehicle 100 at 2.5 bar, thereby ensuring that the boiling point of the heat exchange medium is higher than the normal operating temperature, which can not only optimize the heat exchange efficiency, save energy and reduce emissions, and improve energy efficiency, but also 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 invention, Figure 1 As shown, the vehicle 100 may also include: a first heat exchanger 14, in which a first heat exchange flow path and a second heat exchange flow path are formed, the first heat exchange flow path and the second heat exchange flow path cooperate in heat exchange, the first heat exchange flow path is configured as a part of the exhaust gas emission branch 41, and the second heat exchange flow path is configured as a part of the first heat exchange medium flow path 10.
[0044] Among them, the first heat exchanger 14 can be a heat exchanger of the type of partition heat exchanger, counter-flow heat exchanger, etc., but the present invention is not limited thereto, and the first heat exchanger 14 can be reasonably selected and applied according to actual conditions. This application takes the first heat exchanger 14 as a counter-flow heat exchanger as an example for explanation. In the heat exchange process of the counter-flow heat exchanger, heat is transferred from the hot fluid to the cold fluid through the tube wall, thereby realizing the transfer of thermal energy, and the cold and hot fluids flow in countercurrent, so that the contact time of the cold and hot fluids in the first heat exchanger 14 is longer, so that the heat transfer is more sufficient, and the heat exchange efficiency can be improved. And the first heat exchanger 14 can be made of high temperature resistant and corrosion resistant alloy materials to ensure that the first heat exchanger 14 can still maintain high performance in harsh environments.
[0045] A first heat exchange flow path and a second heat exchange flow path are formed in the first heat exchanger 14. The first heat exchange flow path is configured as a part of the exhaust gas emission branch 41, and high-temperature exhaust gas flows in the first heat exchange flow path. The second heat exchange flow path is configured as a part of the first heat exchange medium flow path 10, and 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 cooperate in heat exchange 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 exchange medium flow path 10 and dissipated into the passenger compartment by the radiator 13, so that the heat of the exhaust gas can be used to heat the passenger compartment, which is beneficial to energy conservation and emission reduction and reducing the overall energy consumption of the vehicle 100.
[0046] According to some embodiments of the present invention, Figure 1 As shown, the vehicle 100 may further include: a second heat exchanger 15, a third heat exchange flow path and a fourth heat exchange flow path are formed in the second heat exchanger 15, the third heat exchange flow path and the fourth heat exchange flow path cooperate in heat exchange, the third heat exchange flow path is constructed as a part of the first heat exchange medium flow path 10, and the fourth heat exchange flow path is constructed as a part of the air conditioning circulation flow path 60.
[0047] Among them, the second heat exchanger 15 can be a water-cooled heat exchanger, a partition-type heat exchanger, and other types of heat exchangers, but the present invention is not limited thereto, and the second heat exchanger 15 can be reasonably selected and applied according to actual conditions. This application takes the second heat exchanger 15 as an example of a water-cooled heat exchanger for explanation. A third heat exchange flow path and a fourth heat exchange flow path are formed in the second heat exchanger 15, the third heat exchange flow path is constructed as part of the first heat exchange medium flow path 10, and a heat exchange medium can flow in the third heat exchange flow path, and the fourth heat exchange flow path is constructed as part of the air conditioning circulation flow path 60, and a high-temperature and high-pressure gas compressed by the compressor 61 can flow in the fourth heat exchange flow path. The third heat exchange flow path and the fourth heat exchange flow path cooperate in heat exchange, so that the heat exchange medium in the third heat exchange flow path can absorb the heat of the high-temperature and high-pressure gas in the fourth heat exchange flow path, and the heat absorbed by the heat exchange medium can be transmitted to the radiator 13 through the first heat exchange medium flow path 10 and dissipated into the passenger compartment by the radiator 13.
[0048] According to some embodiments of the present invention, the exhaust gas emission branch 41 may be provided with an on-off valve, and the exhaust gas emission branch 41 can be opened or blocked by opening or closing the on-off valve. Specifically, when the temperature is low in winter, when it is necessary to recover the heat in the exhaust gas of the engine 42 for heating the passenger compartment, power battery 51 and other parts of the vehicle 100, the on-off valve can be opened to conduct the exhaust gas emission branch 41, so as to achieve the heat exchange coordination between the first heat exchange medium flow path 10 and the exhaust gas emission branch 41, so that 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 achieve the recovery of the waste heat of the exhaust gas of the engine 42, and use the heat of the exhaust gas to heat the passenger compartment, power battery 51 and other parts of the vehicle 100, which is conducive to improving the energy utilization rate of the engine 42 system, realizing the effective utilization of the heat energy of the exhaust gas, and also can reduce the exhaust temperature of the exhaust gas, which helps to reduce the thermal pollution of the emission. When the temperature is high in summer, there is no need to heat the passenger compartment, power battery 51 and other parts of the vehicle 100. At this time, the on-off valve can be closed to block the exhaust gas emission branch 41. The first heat exchange medium flow path 10 and the exhaust gas emission branch 41 no longer cooperate in heat exchange, which can reduce unnecessary energy consumption and thus improve the efficiency of the vehicle 100.
[0049] Therefore, the design of the on-off valve provides the engine 42 system with higher flexibility and energy efficiency. By flexibly adjusting the state of the on-off valve according to the season and vehicle 100 needs, the heat in the exhaust gas of the engine 42 can be recovered and utilized to the maximum extent, while reducing energy consumption and thermal pollution of emissions.
[0050] According to some embodiments of the present invention, Figure 1 As shown, the vehicle 100 may also include: a third heat exchange medium flow path 30, the third heat exchange medium flow path 30 has a seventh interface and an eighth interface, the third heat exchange medium flow path 30 and the air conditioning circulation flow path 60 cooperate in heat exchange, and the connecting regulating valve 80 is connected to the seventh interface and the eighth interface.
[0051] Among them, Figure 1 As shown, the third heat exchange medium flow path 30 has a seventh interface and an eighth interface, the seventh interface is an H interface, the eighth interface is an I interface, and the connecting regulating valve 80 is connected to the seventh interface and the eighth interface. The connecting regulating valve 80 can selectively connect the seventh interface and the eighth interface with other interfaces to form different functional modes, thereby improving the functionality and performance of the vehicle 100.
[0052] The third heat exchange medium flow path 30 and the air conditioning circulation flow path 60 are heat exchange coordinated. 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, so that the third heat exchange medium flow path 30 and the air conditioning circulation flow path 60 are heat exchange coordinated.
[0053] According to some embodiments of the present invention, Figure 1 As shown, the vehicle 100 may further include: a third heat exchanger 31, 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.
[0054] Among them, the present application takes the third heat exchanger 31 as an evaporator as an example for explanation, but the present invention is not limited to this.
