[0002] As cars become more and more popular, people's requirements for vehicle comfort are also increasing.

[0003] When the weather is cold, people usually turn on the vehicle's heating system when riding in a vehicle to increase the temperature inside the vehicle, thereby improving people's comfort in the vehicle.

[0004] In existing vehicles, the heating system consumes a lot of energy during operation, which affects the vehicle's endurance. Utility Model Content

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The embodiment of the present application provides a vehicle, including a vehicle body, a battery thermal management system and a heating component. The battery thermal management system is arranged on the vehicle body for thermal management of the battery. The heating component is arranged in the cabin, and the two ends are respectively connected to the battery thermal management system.

[0008] According to the above technical means, the vehicle provided by the embodiment of the present application has a heating component disposed in the cabin, and both ends are connected to the battery thermal management system. The circulating refrigerant of the battery thermal management system can enter the heating component, and the heat of the circulating refrigerant can be transferred to the heating component, and the heating component can use the waste heat of the circulating refrigerant of the battery thermal management system to heat the cabin. The people in the cabin do not need to consume additional energy to heat themselves with the heating component, which can reduce energy consumption and thus ensure the vehicle's endurance.

[0009] In some embodiments, the heating assembly includes a first circulation pipeline and a first valve group. The first circulation pipeline is arranged in the cabin, and both ends of the first circulation pipeline are respectively connected to the battery thermal management system. The first valve group is used to control the flow of circulating refrigerant of the battery thermal management system in the first circulation pipeline.

[0010] According to the above technical means, since the two ends of the first circulation pipeline are respectively connected to the battery thermal management system. The circulating refrigerant in the battery thermal management system can enter the first circulation pipeline. Since the first circulation pipeline is arranged in the cabin, during the flow of the circulating refrigerant in the first circulation pipeline, the heat can be dissipated into the cabin, thereby increasing the temperature in the cabin. When the personnel in the cabin need heating, the first valve group can be in an open state, and the circulating refrigerant can flow through the first circulation pipeline after the first valve group is opened. When the personnel in the cabin do not need heating, the first valve group can be in a closed state, and the circulating refrigerant cannot enter the first circulation pipeline after the first valve group is closed. The personnel in the cabin can control the opening and closing of the first valve group according to actual needs.

[0011] In some embodiments, the battery thermal management system includes a driver, a second circulation pipeline, a refrigeration assembly, and a second valve group. The second circulation pipeline includes a first circulation section, a second circulation section, a third circulation section, and a fourth circulation section. One end of the first circulation section and the second circulation section are respectively connected to the driver. The two ends of the third circulation section and the fourth circulation section are respectively connected to the other end of the first circulation section and the second circulation section. The refrigeration assembly is arranged on the fourth circulation section. The second valve group is used to control the circulation of the circulating refrigerant flow in the third circulation section or the fourth circulation section.

[0012] According to the above technical means, since the refrigeration component is arranged on the fourth circulation section, the second valve group is used to control the circulation of the circulating refrigerant flow in the third circulation section or the fourth circulation section. People in the cabin can adjust the second valve group according to actual needs to make the circulating refrigerant flow from the third circulation section or the fourth circulation section.

[0013] In some embodiments, the second valve group includes a first three-way valve having a first port, a second port and a third port, the other end of the first flow section is connected to the first port, one end of the third flow section is connected to the second port, and one end of the fourth flow section is connected to the third port.

[0014] According to the above technical means, when the first port is connected to the second port, the circulating refrigerant of the battery thermal management system can enter the third circulation section after passing through the first three-way valve. At this time, the circulating refrigerant will not pass through the refrigeration component on the fourth circulation section. When the first port is connected to the third port, the circulating refrigerant of the battery thermal management system can enter the fourth circulation section after passing through the first three-way valve. At this time, the circulating refrigerant will pass through the refrigeration component, and the refrigeration component can reduce the temperature of the circulating refrigerant, thereby ensuring the cooling effect of the circulating refrigerant on the battery pack.

[0015] In some embodiments, one end of the first circulation pipeline is communicated with the third circulation section, and the other end is communicated with the second circulation section. The first valve group includes a two-way valve, and the two-way valve is disposed on the first circulation pipeline.

[0016] According to the above technical means, since one end of the first circulation pipeline is connected to the third circulation section and the other end is connected to the second circulation section, the circulating refrigerant can flow into the first circulation pipeline after entering the third circulation section.

[0017] In some embodiments, the first circulation pipeline includes a first connecting section, a heating section, and a second connecting section. One end of the first connecting section is connected to the third circulation section. One end of the heating section is connected to the other end of the first connecting section, and the heating section is bent multiple times to form a plurality of U-shaped tubes connected in sequence. One end of the second connecting section is connected to the other end of the heating section, and the other end of the second connecting section is connected to the second circulation section.

[0018] According to the above technical means, since the heating section is bent multiple times to form multiple U-shaped tubes connected in sequence, the heating section has a larger surface area. When the circulating refrigerant passes through the heating section, the heat of the circulating refrigerant is easy to dissipate into the cabin.

[0019] In some embodiments, the second valve group further includes a second three-way valve. The second three-way valve has a fourth port, a fifth port and a sixth port. The fourth port is communicated with the other end of the second flow section, the fifth port is communicated with the other end of the third flow section, and the sixth port is communicated with the other end of the fourth flow section.

[0020] According to the above technical means, in actual applications, the user can control the connectivity between the three ports of the second valve group according to actual usage requirements to control the flow path of the circulating refrigerant.

[0021] In some embodiments, the heating assembly further comprises a mounting member, which is arranged in the cabin and connected to the vehicle body, and has a mounting groove, in which the heating section is arranged.

[0022] According to the above technical means, since an installation groove is provided on the installation component and the heating section is arranged in the installation groove, the installation groove can provide protection for the heating section.

[0023] In some embodiments, the heating assembly further comprises a shielding member, which is connected to the mounting member and covers the notch of the mounting slot.

[0024] According to the above technical means, since the shielding member covers the slot of the installation slot, the shielding member can prevent debris from falling into the installation slot, making it easier for people to clean and tidy up the cabin. At the same time, the shielding member can also protect the heating section in the installation slot.

[0025] In some embodiments, the cabin has a bottom wall, a side wall and a top wall, the bottom wall and the top wall are arranged opposite to each other and spaced apart, and the side wall is arranged between the bottom wall and the top wall. The heating component is arranged on the bottom wall.

[0026] According to the above technical means, since the heating component is arranged on the bottom wall, the heating component can heat the gas in the cabin from bottom to top, and the heating component can effectively relieve the coldness of the feet and legs of the people in the cabin.

[0027] Therefore, the above technical features of the present application have the following beneficial effects:

[0028] (1) The circulating refrigerant of the battery thermal management system can enter the heating component, and the heat of the circulating refrigerant can be transferred to the heating component. The heating component can use the waste heat of the circulating refrigerant of the battery thermal management system to heat the interior of the cabin.

[0030] (3) People in the cabin can adjust the second valve group according to actual needs to allow the circulating refrigerant to flow from the third circulation section or the fourth circulation section.

[0031] (4) When the first port is connected to the second port, the circulating refrigerant of the battery thermal management system can enter the third circulation section after passing through the first three-way valve. At this time, the circulating refrigerant will not pass through the refrigeration component on the fourth circulation section.

At this time, the circulating refrigerant will pass through the refrigeration component, and the refrigeration component can reduce the temperature of the circulating refrigerant, thereby ensuring the cooling effect of the circulating refrigerant on the battery pack.

[0032] (5) Since one end of the first circulation pipeline is connected to the third circulation section and the other end is connected to the second circulation section, the circulating refrigerant can flow into the first circulation pipeline after entering the third circulation section.

[0033] (6) Since the heating section is bent multiple times to form multiple U-shaped tubes connected in sequence, the heating section has a larger surface area.

DETAILED DESCRIPTION

[0049] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0050] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0051] With the development of automobile manufacturing technology, the usage rate of automobiles in people's lives is getting higher and higher. At the same time, with the improvement of people's living standards, more and more people will pay attention to the experience effects of various aspects of automobiles.

[0052] A car can mainly include an engine, a chassis, a body and electrical equipment. Among them, the electrical equipment can include a heating system. When the weather is cold, people usually turn on the heating system to keep the interior of the car at a suitable temperature.

[0053] In the related art, for fuel vehicles, the heating system can use the waste heat of the engine coolant to heat. For example, the car engine coolant can flow through a heat exchanger, and the cold air in the car passes through the heat exchanger driven by the blower, and the heat of the coolant can be transferred to the air, thereby increasing the temperature of the air passing through the heat exchanger.

[0054] Alternatively, the waste heat of the engine's exhaust system can be used for heating. For example, the exhaust gas generated by the engine can pass through a heat exchanger. The heat exchanger transfers the heat of the exhaust gas to the air, and the air enters the vehicle under the drive of the blower.

[0055] The heating methods of the above two fuel vehicles both require a blower to drive the gas flow, and the operation of the blower requires additional energy consumption.

[0056] For pure electric vehicles, since they do not have the waste heat of traditional internal combustion engines to utilize, in related technologies, pure electric vehicles will use air source heat pump technology to absorb heat energy from outdoor air and convert it into heat energy for indoor heating. In the above process, it is inevitable to consume electricity. This will affect the endurance of pure electric vehicles.

[0057] Based on this, an embodiment of the present application provides a vehicle, such as Figure 1 As shown, Figure 1 FIG. 1 is a schematic diagram of the structure of a vehicle 100 provided in the present application. The vehicle 100 may include a vehicle body 1, and a cabin 11 is formed inside the vehicle body 1. Figure 1 As shown, the cabin 11 has a bottom wall 111 , a side wall 112 and a top wall 113 . The top wall 113 is disposed opposite to the bottom wall 111 and spaced apart from each other, and the side wall 112 is disposed between the bottom wall 111 and the top wall 113 .

[0058] like Figure 2 As shown, Figure 2 This is one of the schematic diagrams of the circulating refrigerant flow path of the vehicle 100 provided in the embodiment of the present application. The vehicle 100 may also include a battery thermal management system 2 and a heating component 3. The battery thermal management system 2 is arranged on the vehicle body 1 ( Figure 1 ) for thermal management of the battery.

[0059] The heating assembly 3 is arranged in the cabin 11, and both ends of the heating assembly 3 are connected to the battery thermal management system 2. In this way, the circulating refrigerant of the battery thermal management system 2 can enter the heating assembly 3, and the heat of the circulating refrigerant can be transferred to the heating assembly 3. The heating assembly 3 can use the waste heat of the circulating refrigerant of the battery thermal management system 2 to heat the interior of the cabin 11. The people in the cabin 11 do not need to consume additional energy to heat through the heating assembly 3, which can reduce energy consumption and thus ensure the endurance of the vehicle.

[0060] In some embodiments, the heating component 3 can be disposed on the bottom wall 111 ( Figure 1 In this way, the heating component 3 can heat the gas in the cabin 11 from bottom to top, and the heating component 3 can effectively relieve the coldness of the feet and legs of the people in the cabin 11.

[0061] In some embodiments, Figure 2As shown, the heating assembly 3 may include a first circulation pipeline 31, and the first circulation pipeline 31 is arranged in the cabin 11 ( Figure 1 ), both ends of the first circulation pipeline 31 are respectively connected to the battery thermal management system 2. In this way, the circulating refrigerant in the battery thermal management system 2 can enter the first circulation pipeline 31. Since the first circulation pipeline 31 is arranged in the cabin 11, the heat of the circulating refrigerant can be dissipated into the cabin 11 during the flow of the first circulation pipeline 31, thereby increasing the temperature in the cabin 11.

[0062] In some embodiments, Figure 2 As shown, the first circulation pipeline 31 includes a first connecting section 311, a heating section 312 and a second connecting section 313. The heating section 312 is bent multiple times to form a plurality of U-shaped tubes connected in sequence. In this way, the heating section 312 has a larger surface area, and when the circulating refrigerant passes through the heating section 312, the heat of the circulating refrigerant is easily dissipated to the cabin 11 ( Figure 1 )Inside.

[0063] In some embodiments, Figure 3 As shown, Figure 3 This is one of the structural diagrams of the heating assembly 3 provided in the embodiment of the present application. The heating assembly 3 may also include a mounting member 33. The mounting member 33 is arranged in the cabin 11 ( Figure 1 ) and the vehicle body 1( Figure 1 ) connection. The mounting member 33 is provided with a mounting groove 331, and the heating section 312 is arranged in the mounting groove 331. In this way, the mounting groove 331 can form a protection for the heating section 312.

[0064] For example, the mounting member 33 may be a foam layer, which has a certain strength and can support objects on the surface of the foam layer, thereby preventing the heating section 312 located in the mounting groove 331 from being damaged. The mounting member 33 may be arranged on the cabin 1 ( Figure 1 )1 bottom wall 111 ( Figure 1 ). Accordingly, the heating section 312 is also located on the bottom wall 111 of the cabin 11. In this way, the heating section 312 can heat the gas in the cabin 11 from bottom to top, and the heating section 312 can effectively relieve the coldness of the feet and legs of the people in the cabin 11.

[0065] In some embodiments, Figure 3 As shown, the heating assembly 3 may further include a shielding member 34. The shielding member 34 is connected to the mounting member 33 and covers the notch of the mounting groove 331. In this way, the shielding member 34 can prevent debris from falling into the mounting groove 331, making it easier for people to clean and tidy up the cabin 11 ( Figure 1 ). At the same time, the shielding member 34 can also provide protection for the heating section 312 in the installation groove 331.

[0066] Exemplarily, when the mounting member 33 is disposed on the bottom wall 111 ( Figure 1 ), the shielding member 34 can be located on the side of the mounting member 33 away from the bottom wall. In this way, when the garbage in the cabin falls on the bottom wall 111, the shielding member 34 can block the notch of the mounting groove 331 to prevent the garbage from entering the mounting groove 331.

[0067] like Figure 4 As shown, Figure 4 The second structural diagram of the heating assembly 3 provided in the embodiment of the present application, the shielding member 34 can be a carpet 341, and the carpet 341 has a certain degree of softness, which can improve the comfort of passengers. The carpet 341 and the mounting member 33 can be bonded together by adhesive. In this way, the carpet 341 has good stability after being laid on the mounting member 33 and is not easy to deviate. It is understandable that the carpet 341 can also be connected to the mounting member 33 in other ways, as long as the carpet 341 and the mounting member 33 are connected together with sufficient stability.

[0068] In some embodiments, Figure 2 As shown, the heating assembly 3 may further include a first valve group 32. The first valve group 32 is used to control the flow of the circulating refrigerant of the battery thermal management system 2 in the first circulation pipeline 31. The first valve group 32 can control the flow direction of the circulating refrigerant to control whether the circulating refrigerant enters the first circulation pipeline 31 or not.

[0069] For example, when the people in the cabin 11 need to be heated, the first valve group 32 can control the circulating refrigerant to flow through the first circulation pipeline 31. When the people in the cabin 11 do not need to be heated, the first valve group 32 can block the circulating refrigerant from entering the first circulation pipeline 31.

[0070] In some embodiments, Figure 2 As shown, the first valve group 32 includes a two-way valve 321, which is disposed on the first circulation pipeline 31. The user can control the opening or closing of the two-way valve 321 to start or stop the circulating refrigerant from passing through the first circulation pipeline 31.

[0071] It should be noted that how to control the opening or closing of the two-way valve 321 is a conventional technical means for those skilled in the art, so it will not be described in detail in this application.

[0072] In some embodiments, Figure 2 As shown, the battery thermal management system 2 may include an expansion water tank (not shown in the figure), a driving member 21, a cooling plate 25 and a refrigeration assembly 23. The expansion water tank is used to store circulating refrigerant, and the expansion water tank has a pressure balancing function, which can prevent the circulating refrigerant volume change caused by temperature change from affecting the normal flow of the circulating refrigerant.

[0073] The driving member 21 can drive the coolant to flow, so that the coolant flows from the expansion tank into the cooling plate 25. The cooling plate 25 can be close to or embedded between the battery modules. The coolant can take away the heat generated by the battery module when flowing through the cooling plate 25, thereby avoiding excessive heat accumulation in the battery module.

[0074] For example, the circulating refrigerant may be a cooling liquid, and accordingly, the driving member 21 may be a cooling liquid pump. The driving member 21 may drive the cooling liquid to flow.

[0075] The temperature of the coolant rises after flowing through the cooling plate 25. In order to reduce the temperature of the coolant, in some embodiments, as Figure 2 As shown, after the coolant flows out from the cooling plate 25, it can pass through the refrigeration assembly 23, and the refrigeration assembly 23 can reduce the temperature of the coolant, thereby ensuring that the coolant can effectively absorb the heat of the battery module during multiple cycles.

[0076] In order to achieve the circulation of the cooling liquid, in some embodiments, as Figure 2 As shown, the battery thermal management system 2 further includes a second circulation pipeline 22. Both ends of the first circulation pipeline 31 are respectively connected to the second circulation pipeline 22. In this way, the circulating refrigerant can flow through the first circulation pipeline 31 during the process of flowing in the second circulation pipeline 22.

[0077] The second circulation pipeline 22 includes a first circulation section 221, a second circulation section 222 and a fourth circulation section 224. One end of the first circulation section 221 is connected to the driving member 21, and the cooling plate 25 is disposed on the first circulation section 221. The driving member 21 can drive the coolant to flow into the first circulation section 221 and flow through the cooling plate 25.

[0078] One end of the second flow section 222 is connected to the driving member 21, and both ends of the fourth flow section 224 are respectively connected to the other ends of the first flow section 221 and the second flow section 222. The coolant in the first flow section 221 can enter the fourth flow section 224, and after entering the fourth flow section 224, the coolant can enter the second flow section 222 and flow back to the driving member 21 from the second flow section 222.

[0079] In some embodiments, Figure 2 As shown, the refrigeration component 23 can be arranged on the fourth flow section 224. In this way, the cooling liquid can pass through the refrigeration component 23 when flowing in the fourth flow section 224, and the refrigeration component 23 can reduce the temperature of the cooling liquid.

[0080] In cold weather, when a pure electric vehicle is started, the battery temperature is low. At this time, the battery needs to be heated up to keep the battery in a suitable temperature environment to avoid battery life degradation. In some embodiments, Figure 5 As shown, Figure 5 The second schematic diagram of the circulating refrigerant flow path of the vehicle 100 provided in the embodiment of the present application, the battery thermal management system 2 also includes a third circulation section 223. The two ends of the third circulation section 223 are respectively connected to the other ends of the first circulation section 221 and the second circulation section 222. The circulating refrigerant of the battery thermal management system 2 will not pass through the refrigeration component 23 when flowing through the third circulation section 223. In this way, the dissipation of the heat absorbed by the circulating refrigerant from the battery can be reduced, so that the temperature of the battery can be raised to a suitable working state.

[0081] In order to facilitate the control of the flow of the circulating refrigerant, in some embodiments, such as Figure 5 As shown, the battery thermal management system 2 further includes a second valve group 24, which is used to control the circulation of the circulating refrigerant in the third circulation section 223 or the fourth circulation section 224. In this way, the personnel in the cabin 11 can adjust the second valve group 24 according to actual needs to make the circulating refrigerant flow from the third circulation section 223 or the fourth circulation section 224.

[0082] In some embodiments, Figure 6 As shown, Figure 6 The third schematic diagram of the circulating refrigerant flow path of the vehicle 100 provided in the embodiment of the present application, the second valve group 24 includes a first three-way valve 241, the first three-way valve 241 has a first port, a second port and a third port, the other end of the first flow section 221 is connected to the first port, one end of the third flow section 223 is connected to the second port, and one end of the fourth flow section 224 is connected to the third port.

[0083] In this way, when the first port is connected to the second port, the circulating refrigerant of the battery thermal management system 2 can enter the third flow section 223 after passing through the first three-way valve 241. At this time, the circulating refrigerant will not pass through the refrigeration assembly 23 on the fourth flow section 224.

[0084] In some embodiments, Figure 6 As shown, one end of the first circulation pipeline 31 is connected to the third circulation section 223, and the other end is connected to the second circulation section 222. In this way, the circulating refrigerant can flow into the first circulation pipeline 31 after entering the third circulation section 223. At this time, the circulating refrigerant directly enters the first circulation pipeline 31 without cooling down through the refrigeration component 23, which can reduce the heat dissipation during the circulation of the circulating refrigerant, and facilitate the increase of the temperature in the cabin 11.

[0085] Exemplarily, one end of the first connection section 311 is connected to the third circulation section 223, one end of the heating section 312 is connected to the other end of the first connection section 311, one end of the second connection section 313 is connected to the other end of the heating section 312, and the other end of the second connection section 313 is connected to the second circulation section 222. In this way, the circulating refrigerant entering the third circulation section 223 can enter the first circulation pipeline 31 from the first connection section 311, and pass through the first connection section 311, the heating section 312 and the second connection section 313 in sequence.

[0086] like Figure 7 As shown, Figure 7 The fourth schematic diagram of the circulating refrigerant flow path of the vehicle 100 provided in the embodiment of the present application shows that when the first port is connected to the third port, the circulating refrigerant of the battery thermal management system 2 can enter the fourth flow section 224 after passing through the first three-way valve 241. At this time, the circulating refrigerant will pass through the refrigeration component 23, and the refrigeration component 23 can reduce the temperature of the circulating refrigerant, thereby ensuring the cooling effect of the circulating refrigerant on the battery pack.

[0087] In some embodiments, Figure 6 As shown, the second valve group 24 also includes a second three-way valve 242, and the second three-way valve 242 has a fourth port, a fifth port and a sixth port. The fourth port is communicated with the other end of the second flow section 222, the fifth port is communicated with the other end of the third flow section 223, and the sixth port is communicated with the other end of the fourth flow section 224.

[0088] like Figure 5 As shown, the first port of the first three-way valve 241 is connected to the second port, the fourth port of the second three-way valve 242 is connected to the fifth port, and the two-way valve 321 is in a closed state. At this time, the circulating refrigerant enters the third circulation section 223 from the first circulation section 221, and then enters the second circulation section 222 from the other end of the third circulation section 223. During the process of the circulating refrigerant flowing in the third circulation section 223 and the second circulation section 222, since the two-way valve 321 is in a closed state, the circulating refrigerant will not flow into the first circulation pipeline 31, and the heating component 3 will not heat the cabin 11 ( Figure 1 ).

[0089] like Figure 2As shown, the first port of the first three-way valve 241 is connected to the third port, the fourth port of the second three-way valve 242 is connected to the sixth port, and the two-way valve 321 is in a closed state. At this time, the circulating refrigerant enters the fourth circulation section 224 from the first circulation section 221, and then enters the second circulation section 222 from the other end of the fourth circulation section 224. During the process of the circulating refrigerant flowing in the fourth circulation section 224 and the second circulation section 222, since the two-way valve 321 is in a closed state, the circulating refrigerant will not flow into the first circulation pipeline 31, and the heating component 3 will not heat the cabin 11 either.

[0090] like Figure 6 As shown, the first port of the first three-way valve 241 is connected to the second port, the three ports of the second three-way valve are not connected, and the two-way valve 321 is in an open state. At this time, the circulating refrigerant enters the third circulation section 223 from the first circulation section 221, then flows into the first circulation pipeline 31 from the third circulation section 223, and flows into the second circulation section 222 from the other end of the first circulation pipeline 31. In the above process, the circulating refrigerant cools the battery pack without passing through the refrigeration component 23, and directly enters the first circulation pipeline 31. In cold weather, the heat of the battery pack can be fully utilized, which can effectively increase the temperature of the cabin 11 and the battery pack.

[0091] like Figure 7 As shown, the first port of the first three-way valve 241 is connected to the third port, the sixth port of the second three-way valve is connected to the fifth port, and the two-way valve 321 is in an open state. At this time, the circulating refrigerant enters the fourth circulation section 224 from the first circulation section 221, then flows into the third circulation section 223 from the fourth circulation section 224, and flows into the first circulation pipeline 31 from the third circulation section 223. The circulating refrigerant flows through the first circulation pipeline 31 and then enters the second circulation section 222. In the above process, the circulating refrigerant cools the battery pack and then passes through the refrigeration component 23 and then enters the first circulation pipeline 31. The refrigeration component 23 can reduce the temperature of the circulating refrigerant to avoid the excessive temperature of the circulating refrigerant causing discomfort to the personnel in the cabin 11.

[0092] It should be noted that how to detect the temperature of the circulating refrigerant and adjust the internal connectivity of the first three-way valve 241 and the second three-way valve 242 according to the detection results is a conventional technical means for those skilled in the art, so it will not be elaborated in this application.

[0093] In addition, the refrigeration component 23 can adjust its operating power according to the temperature of the circulating refrigerant, so that the circulating refrigerant is kept within a suitable temperature range after flowing through the refrigeration component 23. The above technical means are also conventional technical means for those skilled in the art, so they will not be described in detail in this application.

[0094] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
