Abstract

The utility model provides a vehicle heat pump integrated heat management system, which is characterized in that the working mode of a refrigerant side circulating system can be switched through a four-way valve, the working mode of a water side circulating system can be switched through a multi-way valve, and the four-way valve and the multi-way valve are matched for use, so that the working mode of the refrigerant side circulating system can be switched. The heat exchange modes of the vehicle heat pump integrated heat management system are enriched, and the heat exchange requirements of the vehicle under different use working conditions can be met. Moreover, the refrigerant side circulating system does not directly exchange heat with different parts or spaces of the vehicle, but indirectly exchanges heat with different parts or spaces of the vehicle through the water side circulating system, so that pipelines in the refrigerant side circulating system do not need to be arranged to positions such as a passenger compartment and a power battery which need to exchange heat. In this way, even if the refrigerant side circulation system uses flammable and explosive refrigerants such as R290, the safety of positions such as a passenger compartment and a power battery cannot be affected, and therefore the vehicle heat pump integrated heat management system can be safely applied to the vehicle.

This ensures that even if the refrigerant-side circulation system uses flammable and explosive refrigerants such as R290, it will not affect the safety of the passenger compartment, power battery, or other locations. As a result, the vehicle's heat pump integrated thermal management system can be safely applied to the vehicle. Attached Figure Description

[0076] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0077] like Figure 1 As shown, an embodiment of this utility model provides a vehicle heat pump integrated thermal management system, including a water-side circulation system and a refrigerant-side circulation system. The water-side circulation system includes a multi-way valve 110 and multiple heat exchange loops connected to the multi-way valve 110. The multiple heat exchange loops can individually or in combination exchange heat with different components or spaces of the vehicle. The refrigerant-side circulation system includes a four-way valve 210, a first heat exchanger 220, and a second heat exchanger 230. The first heat exchanger 220 and the second heat exchanger 230 are used to exchange heat with different heat exchange loops in the water-side circulation system. The multi-way valve 110 is used to switch the connection mode of the multiple heat exchange loops, and the four-way valve 210 is used to switch the first heat exchanger 220 and the second heat exchanger 230 to either cool or heat. The multi-way valve 110 and the four-way valve 210 work together to switch between different heat exchange modes of the vehicle heat pump integrated thermal management system.

[0078] In this design, multiple heat exchange loops in the water-side circulation system can individually or in combination exchange heat with different components or spaces of the vehicle. The first heat exchanger 220 and the second heat exchanger 230 in the refrigerant-side circulation system can exchange heat with different heat exchange loops in the water-side circulation system. Thus, the refrigerant-side circulation system does not directly exchange heat with different components or spaces of the vehicle, but rather indirectly through the water-side circulation system. This eliminates the need for piping in the refrigerant-side circulation system to be routed to locations requiring heat exchange, such as the passenger compartment and power battery. Therefore, even if the refrigerant-side circulation system uses flammable and explosive refrigerants such as R290, it will not affect the safety of the passenger compartment or power battery, enabling the safe application of this vehicle heat pump integrated thermal management system in vehicles. Furthermore, the working mode of the refrigerant-side circulation system can be switched via the four-way valve 210, and the working mode of the water-side circulation system can be switched via the multi-way valve 110. By using the four-way valve and the multi-way valve together, compared with the solution that only has a four-way valve or a multi-way valve, the heat exchange modes of the vehicle heat pump integrated thermal management system are enriched, which can meet the heat exchange needs of the vehicle under different operating conditions.

[0079] In this system, one of the first heat exchanger 220 and the second heat exchanger 230 is used for cooling, and the other for heating. The refrigerant-side circulation system also includes a compressor 240, whose inlet and outlet are connected to a four-way valve 210. The first heat exchanger 220 and the second heat exchanger 230 are connected by pipelines, and both are connected to the four-way valve 210. Both the first heat exchanger 220 and the second heat exchanger 230 are plate heat exchangers.

[0080] The outlet fluid of compressor 240 enters the inlet of compressor 240 after passing through four-way valve 210, first heat exchanger 220, second heat exchanger 230, and four-way valve 210; or the outlet fluid of compressor 240 enters the inlet of compressor 240 after passing through four-way valve 210, second heat exchanger 230, first heat exchanger 220, and four-way valve 210. By switching the flow direction of refrigerant through four-way valve 210, the heat exchange state of the first heat exchanger 220 and the second heat exchanger 230 is switched.

[0081] The first heat exchanger 220 and the second heat exchanger 230 can be switched between cooling and heating by the cooperation of the four-way valve 210 and the compressor 240. The first heat exchanger 220 and the second heat exchanger 230 adopt plate heat exchangers. When the refrigerant and antifreeze flow in the plate heat exchanger (flowing separately and not connected), efficient heat exchange can be achieved.

[0082] Furthermore, the vehicle heat pump integrated thermal management system also includes an air conditioning heating core 123 and an air conditioning cooling / heating core 133 installed in the passenger compartment 410 of the vehicle; multiple heat exchange circuits include: a first air conditioning circulation circuit 120 connected to the air conditioning heating core 123 and a second air conditioning circulation circuit 130 connected to the air conditioning cooling / heating core 133; the first air conditioning circulation circuit 120 and the second air conditioning circulation circuit 130 are not connected, or the first air conditioning circulation circuit 120 is connected to the second air conditioning circulation circuit 130 through a multi-way valve 110.

[0083] By using the first air conditioning circulation loop 120 and the second air conditioning circulation loop 130 individually or by using the first air conditioning circulation loop 120 and the second air conditioning circulation loop 130 in combination, heat exchange can be performed on at least one of the air conditioning heating core 123 and the air conditioning cooling and heating core 133, thereby cooling, heating or dehumidifying the passenger compartment of the vehicle.

[0084] In some embodiments, the vehicle heat pump integrated thermal management system further includes an air conditioning heating core 123 and an air conditioning cooling / heating core 133 disposed in the passenger compartment 410 of the vehicle; the plurality of heat exchange circuits include: a first air conditioning circulation circuit 120 connected to the air conditioning heating core 123, a second air conditioning circulation circuit 130 connected to the air conditioning cooling / heating core 133, and an electric drive circulation circuit 150 connected to the vehicle's electric drive system 430; wherein the first air conditioning circulation circuit 120, the second air conditioning circulation circuit 130, and the electric drive circulation circuit 150 are not interconnected; or, the first air conditioning circulation circuit 120 is connected to the electric drive circulation circuit 150 through a multi-way valve 110; or, the second air conditioning circulation circuit 130 is connected to the electric drive circulation circuit 150 through a multi-way valve 110; or, the first air conditioning circulation circuit 120 is connected to the electric drive circulation circuit 150 through a multi-way valve 110, and the electric drive circulation circuit 150 is connected to the second air conditioning circulation circuit 130 through a multi-way valve 110.

[0085] In these embodiments, the connection relationship between the first air conditioning circulation loop 120, the second air conditioning circulation loop 130, and the electric drive circulation loop 150 can be switched according to the vehicle's heat exchange requirements, enabling the vehicle's integrated heat pump thermal management system to have multiple operating modes to meet the vehicle's heat exchange needs under different operating conditions. For example, the electric drive circulation loop 150 can dissipate heat from the first air conditioning circulation loop 120 or the second air conditioning circulation loop 130, or the electric drive circulation loop 150 can transfer heat absorbed from the environment to the first air conditioning circulation loop 120 or the second air conditioning circulation loop 130, or the first air conditioning circulation loop 120 can defrost the electric drive circulation loop 150.

[0086] In some embodiments, the vehicle heat pump integrated thermal management system further includes an air conditioning heating core 123 and an air conditioning cooling / heating core 133 disposed in the passenger compartment 410 of the vehicle; the plurality of heat exchange circuits include: a first air conditioning circulation circuit 120 connected to the air conditioning heating core 123, a battery circulation circuit 140 connected to the vehicle's power battery 420, and an electric drive circulation circuit 150 connected to the vehicle's electric drive system 430; wherein, the first air conditioning circulation circuit 120 is connected to the battery circulation circuit 140 through a multi-way valve 110; or, the first air conditioning circulation circuit 120 is connected to the electric drive circulation circuit 150 through a multi-way valve 110, and the electric drive circulation circuit 150 is connected to the battery circulation circuit 140 through a multi-way valve 110.

[0087] In these embodiments, the connection relationship between the first air conditioning circulation loop 120, the battery circulation loop 140, and the electric drive circulation loop 150 can be switched according to the vehicle's heat exchange requirements, enabling the vehicle's integrated heat pump thermal management system to have multiple operating modes to meet the vehicle's heat exchange needs under different operating conditions. For example, the electric drive circulation loop 150 can dissipate heat from the first air conditioning circulation loop 120 or the battery circulation loop 140, or the electric drive circulation loop 150 can transfer heat absorbed from the environment to the first air conditioning circulation loop 120 or the battery circulation loop 140, or the first air conditioning circulation loop 120 can heat the battery circulation loop 140.

[0088] The system includes multiple heat exchange loops: a first air conditioning circulation loop 120 for heat exchange in the passenger compartment 410; a second air conditioning circulation loop 130 for heat exchange in the passenger compartment 410; a battery circulation loop 140 for temperature regulation of the vehicle's power battery 420; and an electric drive circulation loop 150 for heat exchange in the vehicle's electric drive system 430. These multiple heat exchange loops allow for heat exchange in different components or spaces of the vehicle, ensuring reliable vehicle operation and improving user comfort. The antifreeze in a single heat exchange loop can circulate independently, or different heat exchange loops can be connected and used in combination. The use of four-way valves and multi-way valves enables the vehicle's integrated heat pump thermal management system to have more heat exchange modes, meeting the heat exchange needs of the vehicle under different operating conditions.

[0089] In this solution, the refrigerant-side circulation system in the vehicle heat pump integrated thermal management system is separated from the vehicle's electric drive system 430, power battery 420, and passenger compartment 410. This ensures that even if the refrigerant-side circulation system uses flammable and explosive refrigerants such as R290, it will not affect the safety of the electric drive system 430, power battery 420, and passenger compartment 410, thus improving safety.

[0090] like Figure 1As shown, the first heat exchanger 220 and the first air conditioning circulation loop 120 are heat exchanged in conjunction, and / or the first heat exchanger 220 and the electric drive circulation loop 150 are heat exchanged in conjunction; the second heat exchanger 230 and the second air conditioning circulation loop 130 are heat exchanged in conjunction. Through the first heat exchanger 220 and the second heat exchanger 230 in the refrigerant-side circulation system, heat exchange can be performed with different heat exchange loops in the water-side circulation system. Thus, the refrigerant-side circulation system does not directly heat different components or spaces of the vehicle, but indirectly heats different components or spaces of the vehicle through the water-side circulation system. Even if the refrigerant-side circulation system uses flammable and explosive refrigerants such as R290, it will not affect the safety of the passenger compartment, power battery, etc., thereby enabling the vehicle heat pump integrated thermal management system to be safely applied to the vehicle. The first heat exchanger 220 and the second heat exchanger 230 are heat exchanged in conjunction with corresponding heat exchange loops as needed to meet different heat exchange requirements and achieve multi-mode heat exchange.

[0091] In this design, the multiple heat exchange loops also include a battery circulation loop 140 connected to the vehicle's power battery 420; the water-side circulation system also includes a third heat exchanger 160, through which the second air conditioning circulation loop 130 and the battery circulation loop 140 exchange heat. This allows the second air conditioning circulation loop 130 and the battery circulation loop 140 to be linked and exchange heat via the third heat exchanger 160, enriching the functionality of the vehicle's integrated heat pump thermal management system.

[0092] In some embodiments, the vehicle heat pump integrated thermal management system further includes an air conditioning heating core 123, which is used to heat the passenger compartment 410 of the vehicle. The air conditioning heating core 123 exchanges heat with a first heat exchanger 220 through a pipe. Multiple heat exchange loops include a first air conditioning circulation loop 120, which includes a first water pump 124, a first pipe 121, and a second pipe 122. The two ends of the first pipe 121 are respectively connected to a multi-way valve 110 and the air conditioning heating core 123. The two ends of the second pipe 122 are respectively connected to the air conditioning heating core 123 and the multi-way valve 110. The first water pump 124 is disposed on the first pipe 121 or the second pipe 122. The first pipe 121 is connected to the first heat exchanger 220.

[0093] When it is necessary to heat the passenger compartment 410 of the vehicle through the air conditioning heating core 123, the first heat exchanger 220 is switched to heating mode, and the heat in the first heat exchanger 220 is transferred to the air conditioning heating core 123 through the first pipe 121. In the first heat exchanger 220, antifreeze and refrigerant flow separately, and the antifreeze and refrigerant exchange heat during the flow process.

[0094] like Figure 1As shown, the first air conditioning circulation loop 120 also includes a third pipe 125. The first end of the third pipe 125 is connected to the multi-way valve 110, and the second end of the third pipe 125 is connected to the first pipe 121. The connection point between the second end of the third pipe 125 and the first pipe 121 is located between the first heat exchanger 220 and the air conditioning heating core 123. The third pipe 125 is used to cooperate with other heat exchange loops in the water-side circulation system to associate and exchange heat between the first air conditioning circulation loop 120 and other heat exchange loops, enriching the heat exchange modes of the vehicle heat pump integrated thermal management system.

[0095] In some embodiments, the vehicle heat pump integrated thermal management system further includes an air conditioning heating and cooling core 133, which is used to heat and cool the passenger compartment 410 of the vehicle. The air conditioning heating and cooling core 133 exchanges heat through pipes and a second heat exchanger 230. Multiple heat exchange loops include a second air conditioning circulation loop 130 for heating and cooling the passenger compartment 410 of the vehicle. The second air conditioning circulation loop 130 includes a second water pump 134, a fourth pipe 131, and a fifth pipe 132. The two ends of the fourth pipe 131 are respectively connected to a multi-way valve 110 and the air conditioning heating and cooling core 133. The two ends of the fifth pipe 132 are respectively connected to the multi-way valve 110 and the air conditioning heating and cooling core 133. The second water pump 134 is disposed on the fourth pipe 131 or the fifth pipe 132. The fourth pipe 131 is connected to the second heat exchanger 230.

[0096] The second heat exchanger 230 can be switched to cooling or heating mode. The fourth pipe 131 exchanges heat with the second heat exchanger 230. In this way, the heat or cold in the refrigerant in the second heat exchanger 230 can be transferred to the water in the fourth pipe 131 and then delivered to the air conditioning heating / cooling core 133, so that the air conditioning heating / cooling core 133 can cool or heat the passenger cabin 410.

[0097] like Figure 2 As shown, in some embodiments, based on Embodiment 1, the second air conditioning circulation loop 130 further includes a first proportional three-way valve 135 located in the fourth pipe 131. One end of the first proportional three-way valve 135 is connected to the fifth pipe 132, and the pipe between the first proportional three-way valve 135 and the fifth pipe 132 is connected in parallel with the air conditioning cooling and heating core 133.

[0098] By adjusting the ratio of water supplied from the fourth pipe 131 to the air conditioning heating / cooling core 133 and the fifth pipe 132, the heat exchange effect of the air conditioning heating / cooling core 133 can be adjusted, thus providing better cooling or heating for the passenger cabin 410. The first proportional three-way valve 135 can be a three-way valve.

[0099] like Figures 1 to 3As shown, multiple heat exchange circuits include a battery circulation circuit 140 for temperature regulation of the vehicle's power battery 420.

The battery circulation circuit 140 also includes a sixth pipe 141 and a seventh pipe 142. The two ends of the sixth pipe 141 are connected to a multi-way valve 110 and the battery water-cooling plate, respectively. The two ends of the seventh pipe 142 are connected to the battery water-cooling plate and the multi-way valve 110, respectively. The third water pump 143 is located in either the sixth pipe 141 or the seventh pipe 142. The battery circulation circuit 140 can remove heat generated within the vehicle's power battery 420 or heat the vehicle's power battery 420 to maintain a suitable operating temperature.

[0100] Furthermore, the battery circulation loop 140 also includes an eighth pipe 144, the two ends of which are connected to a multi-way valve 110 and a sixth pipe 141, respectively; the water-side circulation system also includes a third heat exchanger 160, and multiple heat exchange loops include a second air conditioning circulation loop 130 for heating and cooling the passenger compartment 410 of the vehicle, the eighth pipe 144 and the second air conditioning circulation loop 130 being connected to the third heat exchanger 160, respectively.

[0101] Through the above settings, the second air conditioning circulation loop 130 and the battery circulation loop 140 are connected for heat exchange, so as to maintain good heat exchange for the power battery 420 under different operating conditions.

[0102] like Figure 3 As shown, in some embodiments, unlike the embodiments described above, the battery circulation loop 140 further includes a second proportional three-way valve 145 located in the sixth pipeline 141. One end of the second proportional three-way valve 145 is connected to the seventh pipeline 142, and the pipeline between the second proportional three-way valve 145 and the seventh pipeline 142 is connected in parallel with the battery water cooling plate.

[0103] The ratio of water supplied from the sixth pipe 141 to the battery water-cooling plate and the seventh pipe 142 can be adjusted by the second proportional three-way valve 145. This allows the amount of water entering the battery water-cooling plate to be adjusted according to the heat exchange requirements, thereby meeting the heat exchange needs of the power battery 420.

[0104] In some embodiments, the plurality of heat exchange circuits include an electric drive circulation circuit 150 for heat exchange of the vehicle's electric drive system 430. The electric drive circulation circuit 150 includes a ninth pipe 151, a tenth pipe 152, and a radiator 153.
