Description

Technical Field

[0001] This application relates to the field of vehicle thermal management technology, and more specifically, to an integrated thermal management system and vehicle. Background Technology

[0002] The technological development of thermal management systems for new energy vehicles has evolved from simple distributed thermal management of the three electrical components (battery, motor, and electronic control unit) to integrated thermal management, resulting in various systems with coupled thermal coupling. Effective integrated thermal management technology can reduce energy loss caused by temperature issues. For example, operating the battery at a suitable temperature improves its charging and discharging efficiency and reduces energy loss; cooling the motor and electronic control unit can also reduce performance degradation caused by overheating, improving overall energy utilization efficiency. Simultaneously, the thermal management system is a crucial component for ensuring vehicle safety. By monitoring and controlling the temperatures of the battery, motor, and electronic control unit, it can prevent safety accidents such as thermal runaway. The thermal management system can also work in conjunction with the vehicle's air conditioning system, utilizing heat generated by the battery or coolant to heat or cool the passenger compartment, improving passenger comfort. Integrated vehicle thermal management keeps the motor and battery within their optimal operating temperature range for maximum efficiency. Combined with heat pump air conditioning technology, this can further improve the vehicle's range.

[0003] However, in existing hybrid power thermal management systems, the engine, battery, motor, and air conditioning are basically independent. Multiple independent thermal management systems not only have numerous pipes and valves, but also cannot exchange heat with each other, and are relatively expensive.

[0074] The engine exhaust pipe 810 is provided with a catalytic converter 811, a second control valve 812 and a muffler 813 in sequence along the exhaust flow direction.

[0075] The exhaust recirculation pipe 820 has an intake port connected to the engine exhaust pipe 810 and is connected between the catalytic converter 811 and the second control valve 812. The exhaust recirculation pipe 820 is provided with a waste heat recovery device 821 and a third control valve 822 in sequence along the exhaust flow direction.

The second end of the exhaust bypass pipe 830 is connected to the engine exhaust pipe 810 and is connected between the second control valve 812 and the muffler 813. A fourth control valve 831 is provided on the exhaust bypass pipe 830.

[0078] like Figure 1 As shown, the engine intake module includes an engine intake pipe 910 before the turbocharger, an engine intake pipe 920 after the turbocharger, an engine turbocharger cooling circulation pipe 930, and an engine intake air temperature regulating circulation pipe 940.

[0079] The outlet of the engine intake pipe 910 before the turbocharger is connected to the intake port of the turbocharger 911.

[0080] The intake port of the turbocharged intake pipe 920 is connected to the outlet of the turbocharger 911, and an intake air temperature regulator 921 is installed on the turbocharged intake pipe 920.

[0082] The first and second ends of the engine intake air temperature regulating circulation pipeline 940 are respectively connected to the T and S ports of the 24-way valve 1000. The water circuit of the intake air temperature regulator 921 is connected in series on the engine intake air temperature regulating circulation pipeline 940, and a fifth water pump is installed on the engine intake air temperature regulating circulation pipeline 940.

[0083] In this application, the three-way valve 112 and the twenty-four-way valve 1000 can also be replaced by other multi-functional valves, and the embodiments of this application do not limit this.

[0084] In this application, port A of the three-way valve 112 can be connected to port B and port C respectively, but port B and port C cannot be connected to each other, while all ports of the twenty-four-way valve 1000 can be connected to each other.

[0085] In this application, the air conditioning module is a heat pump air conditioner. When the cab needs cooling, the A and B ports of the three-way valve 112 are connected, and the A and C ports of the three-way valve 112 are disconnected. The first expansion valve 114 and the second expansion valve 115 are opened, the third expansion valve 122 is closed, the first control valve 131 is closed, and the compressor 111 runs. The air conditioning module dissipates heat to the environment through the outdoor heat exchanger 113 and cools the cab through the indoor evaporator 1166. If the battery 212 also needs cooling at this time, the third expansion valve 122 is opened at the same time, and the air conditioning cooling circulation pipe 150 and the battery circulation pipe 210 are connected in series. The first water pump 211 runs and absorbs the heat dissipation of the battery 212 through the second heat exchanger 123.

[0086] When heating is required in the cab and motor 313 is running, the A and C ports of the three-way valve 112 are connected, while the A and B ports of the three-way valve 112 are disconnected. The first expansion valve 114 and the second expansion valve 115 are closed, the third expansion valve 122 is opened, and the first control valve 131 is closed. This controls the air conditioning cooling circulation pipe 150 and the motor electronic control circulation pipe 310 to be connected in series, and the air conditioning heating circulation pipe 160 and the warm air circulation pipe 510 to be connected in series. The compressor 111 runs, and the second water pump 311 and the fourth water pump 511 run. The air conditioning module transfers heat to the indoor warm air core 512 through the first heat exchanger 121. The heat dissipation of the electronic control component 312 and the motor 313 is absorbed through the second heat exchanger 123. When the motor 313 is not running, the A and C ports of the three-way valve 112 are connected and the A and B ports of the three-way valve 112 are disconnected. The first expansion valve 114 is opened, the second expansion valve 115 and the third expansion valve 122 are closed, the first control valve 131 is opened, and the air conditioning heating circulation pipe 160 and the warm air circulation pipe 510 are connected in series. The compressor 111 runs and the fourth water pump 511 runs. The air conditioning module transfers heat to the indoor warm air core 512 through the first heat exchanger 121 and absorbs the heat from the environment through the outdoor heat exchanger 113.

[0087] In this application, engine 712 is a turbocharged engine. Air is compressed by turbocharger 911 and enters the engine's post-turbocharged intake manifold 920. The temperature is then regulated by intake air temperature regulator 921 before entering engine 712. Intake air temperature regulator 921 can both heat and cool the air in the engine's post-turbocharged intake manifold 920.

[0088] In this application, the flow direction of exhaust gas from engine 712 can be controlled by the second control valve 812, the third control valve 822, and the fourth control valve 831. When exhaust gas recirculation is required in engine 712, the second control valve 812 and the third control valve 822 are opened, and the fourth control valve 831 is closed. A portion of the exhaust gas from engine 712 enters engine 712 through exhaust gas recirculation pipeline 820, and this portion of exhaust gas is cooled by waste heat recovery device 821; another portion of the exhaust gas from engine 712 flows into the atmosphere after passing through the second control valve 812 and muffler 813.

[0089] When exhaust gas recirculation is not required in engine 712, and exhaust waste heat needs to be recovered, the second control valve 812 and the third control valve 822 are closed, and the fourth control valve 831 is opened. The engine exhaust passes through the catalytic converter 811 and enters the exhaust recirculation pipeline 820, then passes through the waste heat recovery device 821 and then through the exhaust bypass pipeline 830, and finally flows into the engine exhaust pipe 810 after the second control valve 812. The exhaust waste heat of engine 712 is recovered through the waste heat recovery device 821.

[0090] When exhaust gas recirculation is not required in engine 712 and exhaust waste heat is not required to be recovered, the second control valve 812 is opened and the third control valve 822 and the fourth control valve 831 are closed. The exhaust gas from engine 712 flows into the atmosphere after passing through the catalytic converter 811, the second control valve 812 and the muffler 813 in the engine exhaust pipe 810.

[0091] Based on the integrated thermal management system provided in this application, the specific operations for three typical summer operating conditions and four typical winter operating conditions are described.

[0092] Summer operating conditions include Summer Condition 1, Summer Condition 2, and Summer Condition 3.

The first expansion valve 114 is opened, the second expansion valve 115 is opened, the third expansion valve 122 is closed, the first control valve 131 is closed, and the compressor 111 is running. This causes the air conditioning module to dissipate heat to the outside environment through the outdoor heat exchanger 113 and to cool the cab through the indoor evaporator 116.

[0095] The 24-way valve 1000 is controlled to connect ports D and E, ports F and L, ports G and K, ports H and P, ports O and J, ports M and N, ports Q and R, ports S and T, ports V and U, ports W and X, ports Y and Z, and ports A1 and A2. This connects the battery circulation pipe 210 and the first heat dissipation circulation pipe 410 in series, and the motor control circulation pipe 310 and the second heat dissipation circulation pipe 420 in series. The first water pump 211 runs, the second water pump 311 runs, the third water pump 711 stops, the fourth water pump 511 stops, and the fifth water pump 941 stops, so that the battery 212 is cooled by the first heat sink 411, and the control components 312 and the motor 313 are cooled by the second heat sink 421.

The first expansion valve 114 is opened, the second expansion valve 115 is opened, the third expansion valve 122 is opened, the first control valve 131 is closed, and the compressor 111 is running.

[0101] The following connections are established for the 24-way valve 1000: D and T ports, F and E ports, H and G ports, J and S ports, K and A2 ports, L and Q ports, R and A1 ports, M and P ports, O and N ports, V and U ports, W and X ports, and Y and Z ports.
