Description

Technical Field

[0001] This application relates to the field of vehicle parts manufacturing technology, and in particular to a degassing device, a thermal management system, and a vehicle. Background Technology

[0002] The thermal management system of new energy vehicles can ensure vehicle performance, safety and comfort. Its core function is to ensure that key components such as batteries, motors and electronic control systems operate within the optimal temperature range through precise temperature control, while optimizing the comfort of the passenger cabin.

[0003] In the relevant technical solutions, the battery thermal management system of new energy vehicles exchanges heat with the refrigerant in other thermal management systems on the vehicle through heat exchange pipes, eliminating the need for a radiator in the battery thermal management system. Gas generated in the heat exchange pipes of the battery thermal management system is discharged to the expansion tank through a first three-way valve, and after being vented in the expansion tank, it flows back to the heat exchange pipes through a second three-way valve.

[0004] However, due to the high flow rate of the refrigerant in the heat exchange pipes, the refrigerant flowing into the expansion tank may only carry some of the gas in the heat exchange pipes, while the remaining gas continues to flow in the heat exchange pipes, resulting in low degassing efficiency in the heat exchange pipes and affecting the heat exchange efficiency. Utility Model Content

[0005] In view of this, embodiments of this application provide a degassing device, a thermal management system, and a vehicle. This application is beneficial for improving the degassing efficiency in heat exchange pipelines, thereby improving the heat exchange efficiency of the thermal management system.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] This application provides a degassing device, including:

[0008] The main body, wherein a cavity is formed within the main body;

[0009] The water inlet pipe, along the first direction, has a first end connected to a heat exchange pipe, and a second end connected to the cavity;

[0010] The water outlet pipe is located along the first direction, with its first end connected to the cavity and its second end connected to a heat exchange pipe; the water inlet pipe and the water outlet pipe are located at opposite ends of the body along the first direction.

[0011] At least one partition is disposed in the cavity, and the partition is provided with at least one through hole, which is alternately arranged with at least one of the water inlet pipe and the water outlet pipe;

[0012] An exhaust pipe, along the second direction, has its first end connected to the cavity, and its second end connected to the expansion tank; along the first direction, the first end of the exhaust pipe is located between the partition and the outlet pipe;

[0013] Wherein, the first direction and the second direction are perpendicular to each other.

[0014] The degassing device of this application embodiment can be connected in series to the heat exchange pipeline via an inlet water pipe and an outlet water pipe. The cavity inside the main body can realize the partial expansion of the heat exchange pipeline. By setting a baffle in the cavity of the main body and making the through holes on the baffle staggered with at least one of the inlet water pipe and the outlet water pipe, the flow direction of the refrigerant can be changed, the flow time of the refrigerant in the cavity can be increased, the flow rate of the refrigerant can be slowed down, and the amount of gas carried by the refrigerant entering the exhaust pipe can be increased, thereby improving the degassing efficiency in the heat exchange pipeline and thus improving the heat exchange efficiency of the thermal management system.

[0015] In one possible implementation of this application, the cavity is provided with a plurality of partitions, and the plurality of partitions are spaced apart along the first direction;

[0016] The through holes on two adjacent partitions are staggered along the second direction.

[0017] This embodiment of the application, by setting multiple spaced baffles in the cavity, can further increase the flow time of the refrigerant in the cavity, slow down the flow rate of the refrigerant, and increase the amount of gas carried by the refrigerant entering the exhaust pipe, which is beneficial to improving the degassing efficiency in the heat exchange pipe and improving the heat exchange efficiency of the heat management system.

[0018] In one possible implementation of this application, the partition is further provided with an exhaust hole, which is located close to the exhaust pipe.

[0019] In this embodiment, an exhaust hole is provided on the partition plate and is located close to the exhaust pipe. The gas released by the refrigerant entering the cavity can flow to the exhaust pipe through the exhaust hole, which avoids the refrigerant from accumulating in the cavity and thus improves the degassing efficiency.

[0020] In one possible implementation of this application, the partition is welded to the inner wall of the body.

[0021] In this embodiment, the partition is welded to the inner wall of the main body by welding, thereby ensuring the airtightness between the partition and the main body.

[0022] In one possible implementation of this application, the cavity is provided with two partitions, the two partitions being a first partition and a second partition. Along the first direction, the first partition is close to the water inlet pipe, the second partition is close to the water outlet pipe, and the exhaust pipe is located between the second partition and the water outlet pipe.

[0023] The first partition is provided with a plurality of first through holes, and the second partition is provided with a plurality of second through holes. Along the second direction, the water inlet pipe and the water outlet pipe are both located on the side of the body away from the exhaust pipe. The plurality of first through holes are all located close to the exhaust pipe, and the plurality of second through holes are all located away from the exhaust pipe.

[0024] This embodiment of the application arranges the inlet and outlet water pipes on the side of the main body away from the exhaust pipe, and sets multiple first through holes near the exhaust pipe on the first partition and multiple second through holes away from the exhaust pipe on the second partition. This allows the refrigerant entering the cavity to first pass upward through the first through holes into the space between the first and second partitions, then downward through the second through holes into the space between the second partition and the outlet water pipe, and finally exit the cavity through the exhaust pipe and the outlet water pipe. This increases the flow time of the refrigerant in the cavity, slows down the flow rate of the refrigerant, and increases the amount of gas carried by the refrigerant entering the exhaust pipe. This is beneficial for improving the degassing efficiency in the heat exchange pipe and improving the heat exchange efficiency of the heat management system.

[0025] In one possible implementation of this application, the second direction is parallel to the direction of gravity, and the angle between the axis of the exhaust pipe and the second direction is less than 15°.

[0026] In this embodiment, the angle between the axis of the exhaust pipe and the direction of gravity is set to less than 15°, which facilitates the discharge of gas through the exhaust pipe and helps to improve the degassing efficiency.

[0027] In one possible implementation of this application, the ratio of the projected area of ​​the body to the projected area of ​​the water inlet pipe in a plane perpendicular to the first direction is 4-8.

[0028] This embodiment sets the ratio of the projected area of ​​the main body to the projected area of ​​the water inlet pipe in the range of 4-8. This allows the refrigerant flow rate in the cavity to be slowed down to the greatest extent without affecting the normal flow of the refrigerant in the thermal management system, which is beneficial to improving the degassing efficiency.

[0029] In one possible implementation of this application, the main body is further provided with a fixing plate, and the fixing plate is provided with fixing holes.

[0030] This application embodiment provides a fixing plate on the main body and fixing holes on the fixing plate, so that the degassing device can be connected and fixed to the vehicle body by fasteners passing through the fixing holes, which facilitates the installation of the degassing device.

[0031] This application embodiment also provides a thermal management system, including a heat exchange pipeline, an exhaust pipeline, a return pipeline, a battery, a water pump, an expansion tank, a heat exchanger, and a degassing device as described above. The battery, water pump, heat exchanger, and degassing device are all installed on the heat exchange pipeline. The degassing device is also connected to the exhaust pipeline through an exhaust pipe. The exhaust pipeline is connected to the expansion tank. The expansion tank is connected to the heat exchange pipeline through the return pipeline.

[0032] Because the thermal management system of this embodiment employs the aforementioned degassing device, the degassing efficiency within the heat exchange pipes of the thermal management system is relatively high, which is beneficial for improving the heat exchange efficiency of the thermal management system.

[0033] This application also provides a vehicle including the thermal management system described above.

[0034] The vehicle in this embodiment of the application has good heat exchange efficiency due to the adoption of the above-mentioned thermal management system, which is beneficial to improving vehicle performance and ensuring vehicle safety and comfort. Attached Figure Description

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0063] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0064] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0065] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0066] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0067] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0068] As described in the background section, in the battery thermal management system of the related technology, the refrigerant flow rate in the heat exchange pipe is relatively fast. The refrigerant flowing into the expansion tank may only carry part of the gas in the heat exchange pipe, while the remaining gas still flows in the heat exchange pipe, resulting in low degassing efficiency in the heat exchange pipe and affecting the heat exchange efficiency.

[0069] Specifically, such as Figure 1As shown, the related thermal management system includes a heat exchange pipe 20, on which a battery 60, a water pump 70, and a heat exchanger 80 are connected in series. The thermal management system also includes an expansion tank 30, which is connected to the heat exchange pipe 20 via an exhaust pipe 40 and a return pipe 50. Specifically, the heat exchange pipe 20 is also equipped with a first three-way valve 21 and a second three-way valve 22, both connected in series. The first three-way valve 21 is located between the battery 60 and the heat exchanger 80, and the second three-way valve 22 is located between the heat exchanger 80 and the water pump 70. The other port of the first three-way valve 21 is connected to the inlet of the expansion tank 30 via the exhaust pipe 40, and the other port of the second three-way valve 22 is connected to the outlet of the expansion tank 30 via the return pipe 50. A temperature sensor 23 may also be installed on the heat exchange pipe 20 between the water pump 70 and the battery 60 to detect the temperature of the refrigerant entering the battery 60. It is understandable that the battery thermal management system is composed of the above-mentioned components.

[0070] The thermal management system also includes a cooling device 91 and a heating device 93. The cooling device 91 is connected in series with the heat exchanger 80 via a cooling pipe 92, and the heating device 93 is connected in series with the heat exchanger 80 via a heating pipe 94. The refrigerant in the heat exchange pipe 20 can exchange heat with the refrigerant in the cooling pipe 92 or the heating pipe 94 inside the heat exchanger 80 through contact heat exchange, thereby achieving heat exchange. After heat exchange, the water pump 70 can pressurize the refrigerant and deliver it to the battery 60, thereby heating or cooling the battery 60 and keeping the operating temperature of the battery 60 within a suitable range.

[0071] After heat exchange within battery 60, the refrigerant flows to the first three-way valve 21. For example... Figure 2 As shown, the first three-way valve 21 is also connected to the exhaust pipe 40. Within the first three-way valve 21, some refrigerant can carry gas from the exhaust pipe 40 into the expansion tank 30. Under gravity, the gas accumulates at the top of the expansion tank 30, and when a certain pressure is reached, it can be discharged from the expansion tank 30. The gas, after being degassed by the expansion tank 30, flows back to the heat exchange pipe 20 through the return pipe 50 to continue heat exchange.

[0072] Because the cross-sectional area of ​​the first three-way valve 21 is small, the refrigerant flows faster in the first three-way valve 21. Therefore, the refrigerant flowing into the expansion tank 30 may only carry part of the gas in the heat exchange pipe 20, while the remaining gas still flows in the heat exchange pipe 20, resulting in low degassing efficiency in the heat exchange pipe 20 and affecting the heat exchange efficiency.

[0073] In view of this, the embodiments of this application aim to provide a degassing device, a thermal management system, and a vehicle. By providing a degassing device, which can be connected in series to a heat exchange pipeline via an inlet and an outlet water pipe, the cavity within the body of the degassing device can achieve partial expansion of the heat exchange pipeline. By providing a baffle plate within the cavity of the body, and staggering the through holes on the baffle plate with at least one of the inlet and outlet water pipes, the flow direction of the refrigerant can be changed, increasing the refrigerant's flow time within the cavity, slowing down the refrigerant's flow rate, and increasing the amount of gas carried by the refrigerant entering the exhaust pipeline. This is beneficial for improving the degassing efficiency in the heat exchange pipeline, thereby improving the heat exchange efficiency of the thermal management system.

[0074] The embodiments of this application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. It should be noted that the first direction X, the second direction Y, and the third direction Z in the embodiments of this application can be three different directions in three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other, and the second direction Y can be a vertical direction.

[0075] This application provides a degassing device, a thermal management system, and a vehicle for heat exchange of key components within a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, categorized by vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally have wheels, a body, and a thermal management system installed within the body. The thermal management system ensures vehicle performance, safety, and comfort. Its core function is to ensure that key components such as the battery, motor, and electronic control system operate within their optimal temperature range through precise temperature control, while simultaneously optimizing passenger cabin comfort.

[0076] Please refer to Figures 3-11 This application provides a degassing device 10, comprising:

[0077] The body 100 has a cavity 101 formed within it. The volume of the cavity 101 can be set based on the space between adjacent parts on the vehicle. It is understood that the larger the volume of the cavity 101, the longer the refrigerant resides within the body 100, thus resulting in a better degassing effect. Exemplarily, the shape of the body 100 in this embodiment can be set as needed, for example, it can be cylindrical or prismatic. The body 100 can be formed by welding multiple plates. An inlet, an outlet, and an exhaust port can be provided on the body 100.

[0078] The water inlet pipe 200 is located in the first direction X. The first end of the water inlet pipe 200 is connected to the heat exchange pipe 20, and the second end of the water inlet pipe 200 is connected to the cavity 101. It is understood that the second end of the water inlet pipe 200 can be connected to the water inlet on the main body 100 by welding or threaded connection, thereby connecting the second end of the water inlet pipe 200 to the cavity 101.

[0079] The outlet pipe 300, along the first direction X, has its first end connected to the cavity 101, and its second end connected to the heat exchange pipe 20. It is understood that the first end of the outlet pipe 300 can be connected to the outlet on the main body 100 by welding or threaded connection, thereby connecting the first end of the outlet pipe 300 to the cavity 101. The inlet pipe 200 and the outlet pipe 300 are located at opposite ends of the main body 100 along the first direction X, meaning they are positioned on opposite sides of the main body 100, and the refrigerant must pass through the main body 100 before being discharged.

[0080] At least one partition 400 is disposed within the cavity 101, thereby dividing the cavity 101 into two sub-cavities. The partition 400 is provided with at least one through hole, which is staggered with at least one of the inlet pipe 200 and the outlet pipe 300. Thus, refrigerant entering one sub-cavity must pass through the through hole on the partition 400 before entering the next sub-cavity, thereby changing the flow direction of the refrigerant, prolonging the flow time of the refrigerant within the cavity 101, and allowing any gas mixed in with the refrigerant to be fully discharged.

[0081] The exhaust pipe 500, along the second direction Y, has its first end connected to the cavity 101, and its second end connected to the expansion tank 30. It is understood that the first end of the exhaust pipe 500 can be connected to the exhaust port on the main body 100 by welding or threaded connection, thereby connecting the first end of the exhaust pipe 500 to the cavity 101. The exhaust pipe 500 can be vertically upward, i.e., opposite to the direction of gravity, to facilitate gas discharge. Along the first direction X, the first end of the exhaust pipe 500 is located between the partition 400 and the water outlet pipe 300. This ensures that the refrigerant will only be discharged from the exhaust pipe 500 after passing through all the sub-cavities.

[0082] As described above, the degassing device 10 of this embodiment can be connected in series to the heat exchange pipe 20 via the inlet pipe 200 and the outlet pipe 300. The cavity 101 within the main body 100 can achieve partial expansion of the heat exchange pipe 20. By providing a baffle 400 within the cavity 101 of the main body 100, and staggering the through holes on the baffle 400 with at least one of the inlet pipe 200 and the outlet pipe 300, the flow direction of the refrigerant can be changed, increasing the flow time of the refrigerant within the cavity 101, slowing down the refrigerant flow rate, and increasing the amount of gas carried by the refrigerant entering the exhaust pipe 500. This is beneficial to improving the degassing efficiency in the heat exchange pipe 20, thereby improving the heat exchange efficiency of the thermal management system.

[0083] In one possible implementation, the cavity 101 of this embodiment may be provided with a plurality of partitions 400, which are spaced apart along a first direction X. The through holes on two adjacent partitions 400 are staggered along a second direction Y.

[0084] This embodiment of the application provides multiple spaced baffles 400 within the cavity 101, thereby increasing the refrigerant's flow time within the cavity 101, slowing down the refrigerant's flow rate, and increasing the amount of gas carried by the refrigerant entering the exhaust pipe 500. This is beneficial for improving the degassing efficiency in the heat exchange pipe 20 and enhancing the heat exchange efficiency of the thermal management system.

[0085] Furthermore, the partition 400 in this embodiment is also provided with an exhaust hole, which is located near the exhaust pipe 500, that is, the exhaust hole is located at the upper end of the partition 400.

[0086] In this embodiment, an exhaust hole is provided on the partition plate 400, and the exhaust hole is located close to the exhaust pipe 500. The gas released by the refrigerant entering the cavity 101 can flow to the exhaust pipe 500 through the exhaust hole, which avoids the refrigerant from accumulating in the cavity 101, thereby improving the degassing efficiency.

[0087] In this embodiment, the partition 400 and the inner wall of the body 100 can be connected and fixed by welding.

[0088] In this embodiment, the partition 400 is welded to the inner wall of the body 100 by welding, thereby ensuring the airtightness between the partition 400 and the body 100.

[0089] Please continue to refer to Figures 6-8 In a preferred embodiment of this application, the cavity 101 is provided with two partitions 400, including a first partition 410 and a second partition 420. Along the first direction X, the first partition 410 is close to the water inlet pipe 200, the second partition 420 is close to the water outlet pipe 300, and the exhaust pipe 500 is located between the second partition 420 and the water outlet pipe 300.

[0090] The first partition 410 has multiple first through holes 411, and the second partition 420 has multiple second through holes 421. Along the second direction Y, the water inlet pipe 200 and the water outlet pipe 300 are both located on the side of the main body 100 away from the exhaust pipe 500. The multiple first through holes 411 are all located close to the exhaust pipe 500, and the multiple second through holes 421 are all located away from the exhaust pipe 500. The first partition 410 also has a first exhaust hole 412, which is located at the end of the first partition 410 close to the exhaust pipe 500. The second partition 420 also has a second exhaust hole 422, which is located at the end of the second partition 420 close to the exhaust pipe 500.

[0091] In this embodiment, the inlet pipe 200 and outlet pipe 300 are positioned on the side of the main body 100 away from the exhaust pipe 500, and multiple first through holes 411 are provided on the first partition 410 near the exhaust pipe 500, while multiple second through holes 421 are provided on the second partition 420 away from the exhaust pipe 500, thereby changing the flow direction of the refrigerant within the cavity 101. Figure 6 As shown by the middle arrow, the refrigerant entering the cavity 101 first flows upward through the first through-hole 411 into the space between the first partition 410 and the second partition 420, then flows downward through the second through-hole 421 into the space between the second partition 420 and the water outlet pipe 300, and finally exits the cavity 101 through the exhaust pipe 500 and the water outlet pipe 300. Through this scheme, the embodiment of this application is beneficial in increasing the flow time of the refrigerant in the cavity 101, slowing down the refrigerant flow rate, increasing the amount of gas carried by the refrigerant entering the exhaust pipe 500, which is beneficial in improving the degassing efficiency in the heat exchange pipe 20 and improving the heat exchange efficiency of the thermal management system.

[0092] Please continue to refer to Figure 4 In this embodiment of the application, the angle α between the axis of the exhaust pipe 500 and the second direction Y is less than 15°.

[0093] In this embodiment, the angle between the axis of the exhaust pipe 500 and the direction of gravity is set to less than 15°, which facilitates the discharge of gas through the exhaust pipe 500 and helps to improve the degassing efficiency.

[0094] Please continue to refer to Figure 3 , Figure 9 and Figure 10 In a plane perpendicular to the first direction X, the ratio of the projected area S1 of the body 100 in this embodiment to the projected area S2 of the water inlet pipe 200 is 4-8.

[0095] In this embodiment, by setting the ratio of the projected area of ​​the main body 100 to the projected area of ​​the water inlet pipe 200 in the range of 4-8, the flow rate of the refrigerant in the cavity 101 can be slowed down to the greatest extent without affecting the normal flow of the refrigerant in the thermal management system, which is beneficial to improving the degassing efficiency.

[0096] Please continue to refer to Figures 3-6 In this embodiment of the application, the main body 100 is further provided with a fixing plate 600, and the fixing plate 600 is provided with fixing holes 610. Exemplarily, the fixing plate 600 may be located on one side of the main body 100 along the third direction Z. The fixing plate 600 may be fixed to the main body 100 by welding. The fixing hole 610 may be, for example, a through hole or a threaded hole.

[0097] In this embodiment, a fixing plate 600 is provided on the main body 100, and a fixing hole 610 is provided on the fixing plate 600. The degassing device 10 can be connected and fixed to the vehicle body by fasteners such as bolts and screws passing through the fixing hole 610, which facilitates the installation of the degassing device 10.

[0098] Please continue to refer to Figure 11 This application embodiment also provides a thermal management system, including a heat exchange pipe 20, an exhaust pipe 40, a return pipe 50, a battery 60, a water pump 70, an expansion tank 30, a heat exchanger 80, and the aforementioned degassing device 10. The battery 60, water pump 70, heat exchanger 80, and degassing device 10 are all installed on the heat exchange pipe 20. The degassing device 10 is also connected to the exhaust pipe 40 through an exhaust pipe 500. The exhaust pipe 40 is connected to the expansion tank 30. The expansion tank 30 is connected to the heat exchange pipe 20 through the return pipe 50.

[0099] Specifically, the degassing device 10 is installed between the battery 60 and the heat exchanger 80, and a second three-way valve 22 is also installed on the heat exchange pipe 20, which is located between the heat exchanger 80 and the water pump 70. A temperature sensor 23 may also be installed on the heat exchange pipe 20 between the water pump 70 and the battery 60 to detect the temperature of the refrigerant entering the battery 60.

[0100] The thermal management system also includes a cooling device 91 and a heating device 93. The cooling device 91 is connected in series with the heat exchanger 80 via a cooling pipe 92, and the heating device 93 is connected in series with the heat exchanger 80 via a heating pipe 94. The refrigerant in the heat exchange pipe 20 can exchange heat with the refrigerant in the cooling pipe 92 or the heating pipe 94 inside the heat exchanger 80 through contact heat exchange, thereby achieving heat exchange. After heat exchange, the water pump 70 can pressurize the refrigerant and deliver it to the battery 60, thereby heating or cooling the battery 60 and keeping the operating temperature of the battery 60 within a suitable range.

[0101] After heat exchange within the battery 60, the refrigerant flows to the degassing device 10. Part of the refrigerant, carrying gas, enters the expansion tank 30 through the exhaust pipe 500 of the degassing device 10. Under gravity, the gas accumulates at the top of the expansion tank 30. When a certain pressure is reached, it can be discharged from the expansion tank 30. The gas, after being degassed by the expansion tank 30, flows back to the heat exchange pipe 20 through the return pipe 50 and the second three-way valve 22 to continue heat exchange.

[0102] Because the thermal management system of this embodiment uses the above-mentioned degassing device 10, the degassing efficiency in the heat exchange pipeline 20 of the thermal management system is relatively high, which is beneficial to improving the heat exchange efficiency of the thermal management system.

[0103] This application also provides a vehicle including the above-described thermal management system.

[0104] The vehicle in this embodiment of the application has good heat exchange efficiency due to the adoption of the above-mentioned thermal management system, which is beneficial to improving vehicle performance and ensuring vehicle safety and comfort.

[0105] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
