Thermal management system and vehicle

[0001] This application claims priority to Chinese Patent Application No. 202510113854.9, filed on January 22, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of vehicle-mounted equipment technology, and more particularly to a thermal management system and a vehicle. Background Technology

[0003] With the improvement of living standards, cars have become the main means of transportation for families. Cars generally include a thermal management system. The compressor is an important component of the thermal management system, capable of compressing the refrigerant to a high-temperature, high-pressure state to enable subsequent heat exchange processes.

[0004] A compressor typically consists of a motor and electronic control unit, as well as a compressor pump. The motor and electronic control unit requires cooling to ensure the compressor can operate normally. Summary of the Invention

The compressor includes a compression chamber and a cooling channel that are isolated from each other. The compression assembly is connected to the compression chamber. The cooling assembly is connected to the cooling channel.

[0007] The compressor provided in some embodiments of this disclosure has a compression assembly connected to a compression chamber. Refrigerant can flow through the compression assembly, which can compress the refrigerant. Since the cooling assembly is connected to a cooling channel, cooling water can flow through it, allowing the cooling assembly to dissipate heat from the compressor and remove heat generated by the compressor's electric drive assembly. Because the flow rate in the cooling assembly is relatively constant, the cooling effect on the electric drive assembly can be ensured, creating stable cooling conditions.

[0053] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. However, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0056] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection.

[0059] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0060] To manage the heat of various components in a car, a thermal management system is typically included. The compressor is a crucial component of this system, compressing the refrigerant to allow it to continuously absorb and release heat during circulation.

[0061] In related technologies, compressors typically have a refrigerant inlet and a refrigerant outlet, which are connected to the two ends of the refrigerant flow path, respectively. The internal motor and electronic control components (such as the motor and control board) of the compressor utilize the refrigerant for heat dissipation. After entering the compressor, the refrigerant flows through the back of the motor and control board, undergoes heat exchange, and then enters the compressor's pump body for compression.

[0062] However, the flow rate in the refrigerant path adjusts according to vehicle conditions, and this variation range is quite wide. When the refrigerant flow rate is low, the above-mentioned method for cooling the compressor's motor and electronic control system may result in insufficient cooling, posing a risk of overheating and potential failure. Furthermore, the cooling effect on the motor and electronic control system is unstable, leading to low cooling reliability.

[0063] In addition, the low-temperature, low-pressure refrigerant entering the compressor has a lower temperature (usually around 0°C) and better cooling capacity, while the temperature of the motor and electronic control is generally higher (usually around 100°C). Using this refrigerant to cool the motor and electronic control will result in a significant loss of cooling capacity, leading to a large waste of energy utilization.

[0064] Based on this, some embodiments of this disclosure provide a vehicle 2000, the type of which is not limited. For example, the vehicle 2000 can be a new energy vehicle or a gasoline vehicle.

[0065] It is understandable that, in order to achieve the basic functions of a vehicle, the vehicle may include basic components such as a body and a drive mechanism, which will not be further explained here.

[0066] To achieve the vehicle's cooling function, as shown in FIG20, the vehicle 2000 provided in some embodiments of this disclosure may further include a thermal management system 1000, which can dissipate heat from the vehicle's components.

[0067] For example, this thermal management system can regulate the temperature of the passenger compartment. When the vehicle includes a battery pack, the thermal management system can also perform thermal management of the battery pack, enabling it to charge or discharge within a preset temperature range.

[0068] The following is a detailed description of some embodiments of the thermal management system provided in this disclosure. As shown in Figures 1 and 2, Figure 1 is a structural diagram of a thermal management system 1000 according to some embodiments, and Figure 2 is a structural diagram of another thermal management system 1000 according to some embodiments. The thermal management system 1000 may include a compressor 100. The compressor 100 can compress refrigerant, compressing the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant.

[0069] In some embodiments, as shown in Figures 1 and 2, the thermal management system 1000 may further include a compression assembly 200 and a cooling assembly 300. The cooling assembly 300 can be used to circulate coolant, which is used to cool other components. The coolant can circulate within the cooling assembly 300. The compression assembly 200 can be used to circulate refrigerant, which is used to cool other components. The refrigerant can circulate within the compression assembly 200.

[0070] For example, the refrigerant in the compression assembly 200 can be a refrigerant that can switch between liquid and gaseous states at different temperatures. The coolant in the cooling assembly 300 can be a mixture of water and antifreeze.

[0071] The compressor 100 can be connected to the compression assembly 200 and the cooling assembly 300. The cooling assembly 300 cools the relevant components of the compressor 100, and the compressor 100 can also compress the refrigerant in the compression assembly 200.

[0072] Based on this, in order to achieve the above functions, in some embodiments, as shown in FIG3, FIG3 is a structural diagram of a compressor 100 according to some embodiments. The compressor 100 may include a compression chamber 113 (FIG. 4) and a cooling channel 1115 (FIG. 7) that are isolated from each other. The compression assembly 200 is connected to the compression chamber 113, and the cooling assembly 300 is connected to the cooling channel 1115.

[0073] Since the compression assembly 200 is connected to the compression chamber 113, refrigerant can circulate within the compression assembly 200, and the compressor 100 can compress the refrigerant within the compression assembly 200. Since the cooling assembly 300 is connected to the cooling channel 1115, cooling water can circulate within the cooling assembly 300, and the cooling assembly 300 can use the cooling water to dissipate heat from the compressor 100, thereby removing the heat generated by the electric drive assembly 20 (Figure 4) of the compressor 100. Because the flow rate in the cooling assembly 300 is relatively constant, the cooling effect of the electric drive assembly 20 can be guaranteed, creating stable cooling conditions.

[0074] In some embodiments, as shown in FIG3, the compressor 100 may include a housing assembly 10. A compression chamber 113 and a cooling channel 1115 are located within the housing assembly 10. The housing assembly 10 is provided with a cooling inlet 1111 and a cooling outlet 1112. The cooling inlet 1111 and the cooling outlet 1112 are respectively connected to the cooling channel 1115.

[0075] Therefore, by providing a cooling channel 1115 inside the housing assembly 10, and by providing a cooling inlet 1111 and a cooling outlet 1112 on the housing assembly 10, both ends of the cooling component 300 can be connected to the cooling inlet 1111 and the cooling outlet 1112 respectively. Cooling water can flow through the interior of the housing assembly 10, thereby better transferring the heat from the housing assembly 10.

[0076] Accordingly, as shown in Figure 3, the housing assembly 10 is also provided with a compression inlet 1121 and a compression outlet 1122. The compression inlet 1121 and the compression outlet 1122 are respectively connected to the compression chamber 113.

[0077] The two ends of the compression assembly 200 can be connected to the compression inlet 1121 and the compression outlet 1122, respectively. In this way, the refrigerant in the compression assembly 200 can enter the compression chamber 113 through the compression inlet 1121 and flow out from the compression outlet 1122.

[0078] In some embodiments, as shown in FIG3, the housing assembly 10 may include an outer shell 11 and a partition 12. The interior of the outer shell 11 forms a cavity, and the partition 12 divides the cavity into a compression chamber 113 and an electronic control chamber 114. For example, as shown in FIG4, the cavity to the right of the partition 12 is the compression chamber 113, and the cavity to the left of the partition 12 is the electronic control chamber 114.

[0079] As shown in Figure 4, which is a cross-sectional view of a compressor 100 according to some embodiments, the compressor 100 may include an electric drive assembly 20 and a pump assembly 30. The electric drive assembly 20 is disposed in an electronically controlled chamber 114, and the pump assembly 30 is disposed in a compression chamber 113.

[0080] As the coolant flows from the cooling inlet 1111 to the cooling outlet 1112, it dissipates heat from the electric drive assembly 20 within the electronic control chamber 114, carrying away the heat generated by the electric drive assembly 20. Simultaneously, the refrigerant enters the compression chamber 113 from the compression inlet 1121 and flows into the pump assembly 30, where it is compressed into high-temperature, high-pressure refrigerant before flowing out from the compression outlet 1122 for subsequent heat release and absorption in circulation. During this process, because the partition 12 divides the internal cavity of the outer casing 11 into the electronic control chamber 114 and the compression chamber 113, the refrigerant does not need to pass through the electric drive assembly 20, reducing cooling energy consumption.

[0081] It is understood that the structures of the electric drive assembly 20 and the pump assembly 30 provided in some embodiments of this disclosure can be selected according to actual conditions, as long as the electric drive assembly 20 can control the compressor 100 and the pump assembly 30 can compress the refrigerant.

[0082] The structure of the pump assembly 30 can be selected according to actual conditions. For example, the pump assembly 30 may include a fixed scroll plate and a moving scroll plate. The fixed scroll plate can be fixed in the compression chamber 113, and the moving scroll plate can move relative to the fixed scroll plate. When the moving scroll plate moves around the fixed scroll plate according to a predetermined track, the volume of the space between the two will decrease, thereby compressing the gas entering the space. As the moving scroll plate moves, the gas is gradually pushed from the larger outer space into the increasingly smaller inner space until finally the pump assembly 30 discharges the compressed gas.

[0083] To facilitate better heat exchange between the coolant and the electric drive assembly 20, in some embodiments, a cooling channel 1115 may be provided corresponding to the electric drive assembly 20. The cooling channel 1115 can be used to circulate coolant to cool the electric drive assembly 20. In this way, the coolant within the cooling channel 1115 can more effectively remove heat from the electric drive assembly 20.

[0084] It is understood that the partition 12 can be connected to the housing 11 in different ways to divide the cavity inside the housing 11 into an electronically controlled chamber 114 and a compression chamber 113. In some embodiments, as shown in FIG4, the housing 11 includes a first housing 111 and a second housing 112. The first housing 111 forms an electronically controlled chamber 114 with a first opening. The second housing 112 forms a compression chamber 113 with a second opening. The second opening is disposed opposite to the first opening. The partition 12 is located between the first housing 111 and the second housing 112, connected to the first housing 111 and the second housing 112, and covers the first opening and the second opening.

[0085] Therefore, by placing the partition 12 between the first housing 111 and the second housing 112 to cover the first opening and the second opening, the cavity of the outer casing 11 can be divided into the aforementioned electronically controlled chamber 114 and the compression chamber 113, thereby enabling separate flow of coolant and refrigerant.

[0086] Based on the above scheme, in some embodiments, the cooling channel 1115 is formed inside the cavity wall of the first housing 111. The cooling inlet 1111 and the cooling outlet 1112 can be disposed on the first housing 111. In this way, the coolant in the cooling channel 1115 can flow through the cavity wall of the first housing 111. Furthermore, as described above, the first housing 111 forms an electronically controlled chamber 114, and the electric drive assembly 20 is disposed within the electronically controlled chamber 114 of the first housing 111, facilitating the removal of heat from the electric drive assembly 20 by the coolant.

[0087] In some embodiments, as shown in FIG5, which is a cross-sectional view of another compressor 100 according to some embodiments, a partition 12 is located inside and connected to the housing 11. By placing the partition 12 inside the housing 11, the internal cavity of the housing 11 can be directly divided into an electronic control chamber 114 and a compression chamber 113, and the refrigerant and coolant can be allowed to flow separately.

[0088] Furthermore, as shown in FIG6, which is a partial structural diagram of a compressor 100 according to some embodiments, the first housing 111 may include an electronic control housing 1113 and a motor housing 1114 connected to each other. The interiors of the motor housing 1114 and the electronic control housing 1113 are interconnected to form the aforementioned electronic control chamber 114.

[0089] In this case, as shown in Figure 7, which is a cross-sectional view of the compressor 100 in Figure 6, the electric drive assembly 20 may include a drive motor 21 and an electronic control component 22. The drive motor 21 may be disposed inside the motor housing 1114, and the electronic control component 22 may be disposed inside the electronic control housing 1113. The partition 12 may be located on the side of the motor housing 1114 away from the electronic control housing 1113 and connected to the motor housing 1114.

[0090] In order to isolate the compression chamber 113 from the cooling channel 1115, in some embodiments, the cooling channel 1115 can be formed inside the cavity wall of the outer casing 11. In this way, the cooling channel 1115 can be isolated from the compression chamber 113, so that the cooling water in the cooling channel 1115 will not flow into the compression chamber 113.

[0091] Correspondingly, one end of the cooling channel 1115 can be connected to the cooling inlet 1111, and the other end can be connected to the cooling outlet 1112. For example, as shown in Figure 7, the electronic control housing 1113 and the motor housing 1114 can jointly form the aforementioned cooling channel 1115.

[0092] In order to enable the coolant to better dissipate heat from the electric drive assembly 20 within the cooling channels, in some embodiments, as shown in FIG7, cooling channels 1115 are formed inside the cavity wall of the electronic control chamber 114 formed in the housing 11.

[0093] In this way, the coolant can flow inside the housing 11 without flowing into the electronic control chamber 114, thus preventing the coolant from directly contacting the electric drive assembly 20 and avoiding leakage problems. The heat generated by the electric drive assembly 20 can be transferred to the coolant through the housing 11 and carried away by the flow of the coolant.

[0094] In other embodiments, the cooling inlet 1111 and cooling outlet 1112 may also be in communication with the electronic control chamber 114. In this case, the housing assembly 10 may also include a heat-conducting element. The heat-conducting element may be disposed within the electronic control chamber 114, with its two ends communicating with the cooling inlet 1111 and cooling outlet 1112, respectively.

[0095] In this way, heat can be transferred to the coolant through the heat-conducting component, and then carried away by the flow of the coolant. At the same time, the heat-conducting component acts as an insulator, preventing the coolant from directly contacting the electric drive assembly 20. For example, the heat-conducting component can be a heat pipe.

[0096] In some embodiments, the cooling channel 1115 includes a first cooling channel 11141 (FIG. 8) and a second cooling channel 11131 (FIG. 9).

[0097] Based on the scheme shown in Figure 7, in order to form the cooling channel 1115, as shown in Figure 8, which is a structural diagram of a motor housing 1114 according to some embodiments, the motor housing 1114 has a cooling outlet 1112, and the motor housing 1114 can be annular. The motor housing 1114 has a first cooling channel 11141, which extends along the axial direction of the motor housing 1114 and communicates with the cooling outlet 1112.

[0098] In this case, as shown in FIG9, FIG9 is a structural diagram of an electronic control housing 1113 according to some embodiments. A second cooling channel 11131 may be formed on the electronic control housing 1113, and one end of the second cooling channel 11131 is connected to the cooling inlet 1111 (FIG7).

[0099] The other end of the second cooling channel 11131 can be connected to one end of the first cooling channel 11141. Thus, the coolant enters the electrical control housing 1113 from the cooling inlet 1111, and after flowing through the second cooling channel 11131, it flows through the first cooling channel 11141 inside the motor housing 1114 before exiting from the cooling outlet 1112. During its flow through the first cooling channel 11141 and the second cooling channel 11131, the coolant carries away heat from the electrical control chamber 114, achieving a heat dissipation effect.

[0100] Understandably, the location and structure of the cooling channel 1115 can be designed according to actual conditions. For example, as shown in Figure 8, there can be multiple first cooling channels 11141, which are spaced apart circumferentially along the motor housing 1114. These multiple first cooling channels 11141 can be interconnected.

[0101] In this case, as shown in Figure 10, which is an exploded view of a partial structure of a compressor 100 according to some embodiments, the coolant can flow out from the second cooling channel 11131 of the electronic control housing 1113 along the direction indicated by the dashed arrow in Figure 10, enter the motor housing 1114, and then flow back and forth circumferentially along multiple first cooling channels 11141 in the motor housing 1114, finally flowing out from the motor housing 1114. For example, as shown in Figure 11, which is a schematic diagram of the coolant flow direction corresponding to the structure shown in Figure 10, the coolant has a relatively long flow path, allowing for sufficient heat exchange and cooling.

[0102] In some embodiments, as shown in FIG12, FIG12 is a structural diagram of another electronic control housing 1113 according to some embodiments, wherein a plurality of flow grooves 11132 may be formed on the electronic control housing 1113.

[0103] Each flow channel 11132 can be connected to one end of a second cooling channel 11131. Thus, as shown in FIG13, an exploded view of another compressor 100 partial structure according to some embodiments, the coolant can flow out of the second cooling channel 11131 of the electronic control housing 1113 along the direction indicated by the dashed arrow in FIG13, enter the motor housing 1114, and then flow circumferentially back and forth along multiple first cooling channels 11141 between the motor housing 1114 and the electronic control housing 1113, finally flowing out of the motor housing 1114. For example, as shown in FIG14, a schematic diagram of the coolant flow direction corresponding to the structure shown in FIG13, the coolant has a relatively long flow path, allowing for sufficient heat exchange and cooling.

[0104] It is understood that the coolant path can be designed according to actual conditions, as long as the corresponding cooling channel 1115 is designed according to the required flow path. For example, as shown in Figures 15 and 16, Figure 15 is a schematic diagram of another flow direction of a coolant according to some embodiments, and Figure 16 is a schematic diagram of yet another flow direction of a coolant according to some embodiments. The flow directions shown in Figures 15 and 16 can enable the coolant to fully exchange heat and cool, thereby achieving a good heat dissipation effect.

[0105] In some embodiments, as shown in FIG12, the electronic control housing 1113 may have a mounting groove 11133. A second cooling channel 11131 may be formed on the wall of the mounting groove 11133. The cooling inlet 1111 (FIG. 10) may communicate with the mounting groove 11133. In this case, to avoid direct contact between the coolant and the components located in the mounting groove 11133, as shown in FIG. 10, the housing assembly 10 (FIG. 5) may also include a first sealing ring 1116 and a second sealing ring 1117.

[0106] The first sealing ring 1116 can be located within the mounting groove 11133 and has a clearance hole. The clearance hole can be used to control the flow direction of the coolant, allowing the coolant to flow along the extension direction of the clearance hole. The second sealing ring 1117 is located on the side of the first sealing ring 1116 away from the bottom of the mounting groove 11133, covering the clearance hole. In this way, the first sealing ring 1116 and the second sealing ring 1117 can form a closed flow channel within the mounting groove 11133, allowing the coolant to flow within this flow channel and enter the second cooling channel 11131.

[0107] Of course, in some other embodiments, the second cooling channel 11131 may also be directly connected to the cooling inlet 1111. In this case, the coolant will not flow into the interior of the mounting groove 11133, thereby avoiding direct contact with the components inside the mounting groove 11133. Thus, it is unnecessary to provide the first sealing ring 1116 and the second sealing ring 1117.

[0108] Furthermore, as shown in Figure 10, the housing assembly 10 may also include two third sealing rings 1118. One third sealing ring 1118 may be located between the electronic control housing 1113 and the motor housing 1114, serving to seal the connection between the two. The other third sealing ring 1118 may be located between the motor housing 1114 and the partition 12, serving to seal the connection between the partition 12 and the motor housing 1114.

[0109] As shown in Figure 4, the electric drive assembly 20 has an output shaft 211. The output shaft 211 can be connected to the pump body assembly 30 to provide a power source for the pump body assembly. For example, the drive motor 21 can have an output shaft 211.

[0110] To facilitate the connection between the output shaft 211 and the pump body assembly 30, in some embodiments, as shown in FIG17, FIG17 is a structural diagram of a partition 12 according to some embodiments, wherein the partition 12 is provided with a shaft hole 121.

[0111] Therefore, the output shaft 211 of the drive motor 21 of the compressor 100 can pass through the partition 12 through the shaft hole 121, and the output shaft 211 can be installed inside the shaft hole 121. In this way, by providing the shaft hole 121, the connection between the output shaft 211 and the pump body assembly 30 can be realized.

[0112] In some embodiments, a groove 122 is formed on one side of the surface of the partition 12. For example, as shown in FIG. 13, a groove 122 is formed on the surface of the partition 12 near the pump body assembly 30 (FIG. 5). A protrusion is formed on the other side of the groove 122. A shaft hole 121 (FIG. 17) is provided at the bottom of the groove 122.

[0113] In this case, as shown in Figure 4, the compressor 100 may also include a bearing 40. The bearing 40 is disposed within the groove 122 (Figure 13) and sleeved around the output shaft 211. Thus, the groove 122 provides an installation position for the bearing 40, facilitating its placement within the groove 122. Furthermore, by providing the bearing 40, friction on the output shaft 211 can be reduced, enabling the output shaft 211 to rotate smoothly and efficiently.

[0114] To ensure a good sealing effect of the partition 12, in some embodiments, as shown in FIG4, the compressor 100 may further include a shaft seal 41. The shaft seal 41 is sleeved around the output shaft 211 and located on the side of the bearing 40 near the electric drive assembly 20. The inner wall of the shaft seal 41 fits against the output shaft 211. The outer wall of the shaft seal 41 fits against the inner wall of the groove 122 (FIG. 13). Thus, by providing the shaft seal 41 so that its inner wall fits against the output shaft 211, the position of the shaft hole 121 can be well sealed, reducing the probability of refrigerant and coolant flowing into each other through the shaft hole 121.

[0115] In some embodiments, to ensure that the shaft seal 41 is well fixed within the groove 122, as shown in FIG. 4, the compressor 100 may further include a retaining ring 42. The retaining ring 42 is located between the shaft seal 41 and the bearing 40. The retaining ring 42 is elastic and has an interference fit with the inner wall of the groove 122, abutting against each other. Due to the interference fit between the retaining ring 42 and the inner wall of the groove 122, the retaining ring 42 can be relatively stably fixed within the groove 122. Furthermore, since the retaining ring 42 is located between the shaft seal 41 and the bearing 40, it can act as a barrier to prevent the shaft seal 41 from falling out of the groove 122.

[0116] In some embodiments, the groove 122 is stepped. The size of the groove 122 decreases along the direction near the bottom of the groove 122. In this way, since the groove 122 is stepped, the bearing 40, the shaft seal 41, and the retaining ring 42 can be arranged at different positions in the groove 122, which facilitates the arrangement of the bearing 40, the shaft seal 41, and the retaining ring 42.

[0117] For example, the bottom of the groove 122 includes a first stepped surface, a second stepped surface, and a third stepped surface. The second stepped surface is located on the side of the first stepped surface near the pump body assembly 30 and is located on the outer periphery of the first stepped surface. The retaining ring 42 is disposed on the second stepped surface, and the shaft seal 41 is disposed on the first stepped surface. The third stepped surface is located on the side of the second stepped surface near the pump body assembly 30 and is located on the outer periphery of the second stepped surface. The bearing 40 is disposed on the third stepped surface. Thus, through the aforementioned first stepped surface, second stepped surface, and third stepped surface, the shaft seal 41, retaining ring 42, and bearing 40 can be disposed at different positions in the groove 122, facilitating the placement of all three within the groove 122.

[0118] In some embodiments, the partition 12 is further provided with a first flow hole and a second flow hole. The first flow hole is used to allow airflow to balance the air pressure in the electronic control chamber 114 and the compression chamber 113. The second flow hole is used to allow oil from the compressor 100 to flow. Thus, by providing the first flow hole, the airflow in the electronic control chamber 114 and the compression chamber 113 can be kept in balance, while by providing the second flow hole, oil recovery can be achieved.

[0119] For example, there can be multiple first flow holes and multiple second flow holes. These multiple first flow holes and multiple second flow holes can be spaced apart circumferentially along the partition 12. Furthermore, in practical applications, the second flow holes can be located at the lower part of the partition 12, and the first flow holes can be located at the higher part of the partition 12. This allows the oil to flow from a lower position through the second flow holes, facilitating oil flow.

[0120] In some embodiments, the inner diameter of the first flow orifice is any value within the range of 1mm-5mm. When the inner diameter of the first flow orifice is within the above range, the inner diameter of the first flow orifice can ensure smooth airflow.

[0121] For example, the inner diameter of the first flow orifice can be 1mm, 3mm, or 5mm, and can be selected according to the actual situation. Of course, the inner diameter of the first flow orifice can also be other values. For example, the inner diameter of the first flow orifice can be greater than 5mm, or the inner diameter of the first flow orifice can be less than 1mm.

[0122] In some embodiments, the inner diameter of the second flow orifice is any value within the range of 1 mm to 5 mm. Similarly, when the inner diameter of the second flow orifice is within the above range, the inner diameter of the second flow orifice can ensure smooth flow of oil.

[0123] For example, the inner diameter of the second flow orifice can be 1mm, 3mm, or 5mm, and can be selected according to the actual situation. Of course, the inner diameter of the second flow orifice can also be other values. For example, the inner diameter of the second flow orifice can be greater than 5mm, or the inner diameter of the second flow orifice can be less than 1mm.

[0124] As mentioned above, the thermal management system 1000 provided in some embodiments of this disclosure includes a cooling assembly 300. In some embodiments, as shown in FIG1, the cooling assembly 300 may include a first heat exchanger 303. The two ends of the first heat exchanger 303 are connected to a cooling inlet 1111 and a cooling outlet 1112, respectively. Thus, when the coolant flows through the cooling channel 1115, the coolant can carry away the heat generated by the compressor 100, and the coolant carrying heat can flow through the first heat exchanger 303. At this time, the first heat exchanger 303 can exchange heat with the external airflow, carrying away the heat carried by the coolant, thereby achieving cooling and temperature reduction of the coolant.

[0125] In some embodiments, as shown in FIG18, FIG18 is a structural diagram of another cooling system 1000 according to some embodiments, the cooling assembly 300 may further include a cooling pump 301.

[0126] The two ends of the cooling pump 301 can be connected to one end of the first heat exchanger 303 and the cooling outlet 1112, respectively. Alternatively, the two ends of the cooling pump 301 can be connected to the other end of the first heat exchanger 303 and the cooling inlet 1111, respectively. In this way, the cooling pump 301 can provide power so that the coolant can circulate smoothly within the cooling channel 1115 and the first heat exchanger 303.

[0127] As shown in Figure 1, in some embodiments, the cooling assembly 300 may further include a cooling pump 301, a first three-way valve 302, a second three-way valve 304, and a second heat exchanger 305. The first three-way valve 302 has a first port, a second port, and a third port. The first port is connected to one end of the cooling pump 301, and the second port is connected to the cooling outlet 1112. One end of the first heat exchanger 303 is connected to the other end of the cooling pump 301. The second three-way valve 304 has a fourth port, a fifth port, and a sixth port. The fourth port is connected to the other end of the first heat exchanger 303. The fifth port is connected to the cooling inlet 1111. One end of the second heat exchanger 305 is connected to the third port, and the other end is connected to the sixth port.

[0128] Therefore, as shown in Figure 1, when the second and third ports of the first three-way valve 302 are connected to the first port, and the fourth and sixth ports of the second three-way valve 304 are connected to the fifth port, the coolant in the second heat exchanger 305 and the coolant in the compressor 100 can flow through the first three-way valve 302 to the first heat exchanger 303. The coolant cooled after passing through the first heat exchanger 303 can then flow through the second three-way valve 304 to the second heat exchanger 305 and the compressor 100, respectively. The coolant at the second heat exchanger 305 can be used to cool other heat-generating components of the vehicle.

[0129] It is understood that the connection positions of the cooling inlet 1111 and the cooling outlet 1112 in the cooling assembly 300 may differ. For example, as shown in Figure 2, in some embodiments, the cooling inlet 1111 may be connected to the second port of the first three-way valve 302, and the cooling outlet 1112 may be connected to the fifth port of the second three-way valve 304.

[0130] In some embodiments, the first three-way valve 302 and the second three-way valve 304 can be proportional three-way valves. Thus, by adjusting the ratio of the connection sizes of the ports of the first three-way valve 302 and the second three-way valve 304, the flow rate can be controlled.

[0131] In some embodiments, as shown in FIG2, the first heat exchanger 303 includes a plurality of sub-heat exchangers 3031. The plurality of sub-heat exchangers 3031 are connected in series. Thus, the heat exchange effect of the first heat exchanger 303 can be improved by using the plurality of sub-heat exchangers 3031.

[0132] Alternatively, as shown in Figure 19, which is a structural diagram of another cooling system according to some embodiments, in some embodiments, the first heat exchanger 303 may also include a first sub-heat exchanger 3031, which can be selected according to the actual situation.

[0133] In some embodiments, as shown in FIG2, the thermal management system 1000 may further include a plurality of cooling fans 3032. One cooling fan 3032 is located on one side of a sub-heat exchanger 3031 and is used to dissipate heat from the sub-heat exchanger 3031. In this way, the airflow velocity near the sub-heat exchanger 3031 can be increased by the cooling fan 3032, thereby improving the heat exchange effect of the sub-heat exchanger 3031.

[0134] Furthermore, as shown in Figure 19, a cooling fan 3032 can also be provided on one side of the second heat exchanger 305. In this way, the cooling fan 3032 can also increase the airflow velocity near the second heat exchanger 305, thereby improving the heat exchange effect of the second heat exchanger 305.

[0135] In some embodiments, as shown in FIG1, the compression assembly 200 may include a condenser 201, an expansion valve 202, and an evaporator 203 connected in sequence. One end of the condenser 201 is connected to the compression outlet 1122, one end of the expansion valve 202 is connected to the other end of the condenser 201, one end of the evaporator 203 is connected to the other end of the expansion valve 202, and the other end is connected to the compression inlet 1121. In this way, the refrigerant in the compression assembly 200 can enter the compression chamber 113 and be compressed by the pump assembly 30 in the compression chamber 113, thereby becoming a high-temperature and high-pressure refrigerant.

[0136] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
