[0024] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other technical solutions obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0026] To reduce the assembly difficulty of the gas-liquid separator and the compression unit, this application proposes an integrated thermal management device. Please refer to [link to relevant documentation]. Figure 1 , Figure 4 and Figure 6 In some embodiments, the thermal management integrated device includes a gas-liquid separator 2 and a compression unit 3. The gas-liquid separator 2 has an exhaust outlet 245, and the compression unit 3 has an intake port 31a, which communicates with the exhaust outlet 245. The gas-liquid separator 2 includes a gas-liquid separation housing portion 200, and the compression unit 3 includes a compressor housing portion 31. The gas-liquid separation housing portion 200 and the compressor housing portion 31 are connected, and at least partially, they are integral components. The thermal management integrated device of this application includes a gas-liquid separator 2 and a compression unit 3. The gas-liquid separation housing portion 200 of the gas-liquid separator 2 is connected to the compressor housing portion 31 of the compression unit 3. The fact that the gas-liquid separation housing portion 200 and the compressor housing portion 31 are at least partially integral components reduces the assembly difficulty of the gas-liquid separator 2 and the compression unit 3.

[0027] In some embodiments, the gas-liquid separator housing 200 and the compressor housing 31 can be manufactured as a single piece by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc.

[0028] Please see Figure 4 In some embodiments, the length direction of the gas-liquid separator housing 200 is consistent with the length direction of the compressor housing 31, and both the gas-liquid separator housing 200 and the compressor housing 31 are extruded parts. The fact that the gas-liquid separator housing 200 and the compressor housing 31 are consistent in length direction allows them to be extruded as a single unit, reducing processing and assembly requirements and thus lowering processing difficulty.

[0029] Please see Figure 4 In order to reduce the processing difficulty, in some embodiments, the gas-liquid separator 2 has a gas-liquid separation chamber 21, the extension direction of the gas-liquid separation chamber 21 is consistent with the length direction of the gas-liquid separation housing 200; so that the gas-liquid separation chamber 21 and the gas-liquid separation housing 200 can be integrally extruded and molded, which can reduce the processing requirements.

[0030] Please see Figure 4In some embodiments, the compressor housing portion 31 has a mounting cavity 310, the extension direction of which is consistent with the length direction of the compressor housing portion 31. This allows the mounting cavity 310 and the compressor housing portion 31 to be integrally extruded, reducing processing requirements. In other embodiments, when the gas-liquid separation housing portion 200 and the compressor housing portion 31 are aligned in length, the gas-liquid separation housing portion 21, the mounting cavity 310, the gas-liquid separation housing portion 200, and the compressor housing portion 31 can be integrally extruded, further reducing processing requirements.

[0031] Please see Figure 1 , Figure 4 , Figure 6 and Figure 8 In some embodiments, the gas-liquid separator 2 has at least two gas-liquid separation chambers 21. The gas-liquid separator 2 includes a separation baffle 22, which is connected to the gas-liquid separation housing 200. The separation baffle 22 is at least partially located between two adjacent gas-liquid separation chambers 21. The gas-liquid separator 2 has an air passage 23, which communicates with the two adjacent gas-liquid separation chambers 21.

[0032] To further reduce assembly difficulty, the gas-liquid separation section 2a of the gas-liquid separator 2 is at least partially a single piece. Specifically, in some embodiments, the separation baffle 22 and the gas-liquid separation housing section 200 are at least partially a single piece; the separation baffle 22 and the gas-liquid separation housing section 200 can be manufactured into a single piece by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc.

[0033] Please see Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the separation baffle 22 and the gas-liquid separation housing 200 can be integrally extruded. Specifically, the length direction of the separation baffle 22 is consistent with the length direction of the gas-liquid separation housing 200; the separation baffle 22 and the gas-liquid separation housing 200 can be integrally extruded.

[0034] Please see Figure 9In some embodiments, the separation baffle 22 includes a first end face 220a and a second end face 220b, which are located at opposite ends of the separation baffle 22 along its length. An air passage 23 extends through the first end face 220a and the second end face 220b along the length of the separation baffle 22. The extrusion direction of the separation baffle 22 and the gas-liquid separation housing 200 is consistent with the length direction of the gas-liquid separation housing 200. The separation baffle 22 and the gas-liquid separation housing 200 can be integrally extruded with the compressor housing 31, further reducing assembly difficulty. In some embodiments, the air passage 23 extending through the first end face 220a and the second end face 220b can be naturally formed after the separation baffle 22 is extruded, reducing machining requirements. Alternatively, the separation baffle 22 can be extruded and then machined to form the air passage 23.

[0035] Please see Figure 4 , Figure 6 and Figure 9 In some embodiments, the suction port 31a is located in the compressor housing 31, and the discharge port 245 is located in the gas-liquid separator housing 200. In some embodiments, the suction chamber of the compression unit 3 is connected to the suction port 31a, and the discharge port 245 is connected to the exhaust oil return chamber 26 of the gas-liquid separator 2. The suction port 31a and the discharge port 245 can be connected by a pipe or directly.

[0036] To further reduce assembly difficulty, in some embodiments, the intake port 31a of the compression unit 3 and the exhaust port 245 of the gas-liquid separator 2 are directly connected through the intake channel 300a. This reduces the use of piping between the compression unit 3 and the gas-liquid separator 2, and makes the overall structure more compact. Specifically, in some embodiments, the thermal management integrated device has an intake channel 300a, a portion of which is located in the gas-liquid separator housing 200, and another portion of which is located in the compressor housing 31. The intake port 31a and the exhaust port 245 are connected to the intake channel 300a.

[0037] Please see Figure 4 To further reduce assembly difficulty, the flow channel portion 11 is integrated with the gas-liquid separation housing portion 200 and the compressor housing portion 31. Specifically, in some embodiments, the thermal management integrated device further includes a flow channel component 1, which includes the flow channel portion 11. The flow channel portion 11 is connected to at least one of the gas-liquid separation housing portion 200 and the compressor housing portion 31, and the flow channel portion 11 has a flow channel cavity 110.

[0038] In some embodiments, the flow channel portion 11 is at least partially integral with the gas-liquid separation housing portion 200 and the compressor housing portion 31. The flow channel portion 11, gas-liquid separation housing portion 200, and compressor housing portion 31 can be manufactured into an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. In one specific embodiment, the flow channel portion 11, gas-liquid separation housing portion 200, and compressor housing portion 31 are integrally extruded, which reduces processing and assembly requirements, thereby reducing processing difficulty.

[0039] Of course, in some other embodiments, the flow channel 11 may also be connected to at least one of the gas-liquid separation housing 200 and the compressor housing 31 in an assembled manner.

[0040] Please see Figure 4 In some embodiments, the length direction of the flow channel portion 11 is aligned with the length direction of at least one of the gas-liquid separator housing portion 200 and the compressor housing portion 31; this allows the flow channel portion 11 to be integrally extruded with at least one of the gas-liquid separator housing portion 200 and the compressor housing portion 31, reducing processing and assembly requirements and thus lowering processing difficulty. In a specific embodiment, the flow channel portion 11, the gas-liquid separator housing portion 200, and the compressor housing portion 31 are integrally extruded.

[0041] Please see Figure 4 In some embodiments, at least one flow channel cavity 110 extends in the same direction as the length of the flow channel portion 11. This allows at least one flow channel cavity 110 of the flow channel portion 11 to be integrally extruded during the extrusion of the flow channel portion 11, thereby reducing processing difficulty. In some specific embodiments, all flow channel cavities 110 extend in the same direction, allowing all flow channel cavities 110 to be integrally extruded with the flow channel portion 11, and then sealed with a plug to form the flow channel, further reducing processing difficulty. The slots and holes used to connect the flow channel with other components can be machined.

[0042] Please see Figure 7 In some embodiments, the compressor housing 31 has an exhaust port 31b, and the flow channel 11 has a refrigerant inlet 119a. The exhaust port 31b and the refrigerant inlet 119a are connected. The exhaust port 31b and the refrigerant inlet 119a can be connected by a pipe or directly.

[0043] Please see Figure 7To further reduce assembly difficulty, the exhaust port 31b of the compression unit 3 and the refrigerant inlet 119a of the flow channel section 11 are connected through an exhaust channel 300b. This reduces the use of piping between the compression unit 3 and the flow channel section 11, and makes the overall structure more compact. Specifically, the thermal management integrated device has an exhaust channel 300b, a part of which is located in the flow channel section 11, and another part of which is located in the compressor housing section 31. The exhaust port 31b and the refrigerant inlet 119a are connected to the exhaust channel 300b. The flow channel component 1 has a first flow channel 110a, and the exhaust channel 300b is connected to the first flow channel 110a.

[0044] Please see Figure 7 and Figure 9 The gas-liquid separation housing 200 has a separation chamber inlet 243, and the flow channel 11 has a refrigerant outlet 119b. The separation chamber inlet 243 and the refrigerant outlet 119b are connected. The separation chamber inlet 243 and the refrigerant outlet 119b can be connected by a pipe or directly.

[0045] Please see Figure 7 and Figure 9 To further reduce assembly difficulty, in some embodiments, the inlet 243 of the separation chamber of the gas-liquid separator 2 is connected to the refrigerant outlet 119b of the flow channel 11 via an inlet channel 200a. This reduces the use of pipes between the gas-liquid separator 2 and the flow channel 11, resulting in a more compact overall structure. Specifically, in some embodiments, the thermal management integrated device has an inlet channel 200a, a portion of which is located in the flow channel 1, and another portion of which is located in the gas-liquid separator housing 200. The separation chamber inlet 243 and the refrigerant outlet 119b are connected to the inlet channel 200a. The flow channel 1 has a sixth flow channel 110f, and the inlet channel 200a is connected to the sixth flow channel 110f.

[0046] To reduce the manufacturing difficulty of gas-liquid separators, this application proposes an integrated thermal management device. Please refer to [link to relevant documentation]. Figures 1 to 4 , Figure 8 , Figure 9 In some embodiments, the thermal management integrated device includes a gas-liquid separator 2, see [link to relevant documentation]. Figure 3 The gas-liquid separator 2 includes a gas-liquid separation section 2a, please refer to [link / reference]. Figure 8 The gas-liquid separation unit 2a includes a separation baffle 22 and a gas-liquid separation chamber 24. The gas-liquid separation chamber 24 has at least two gas-liquid separation cavities 21. The separation baffle 22 is at least partially located between two adjacent gas-liquid separation cavities 21. The gas-liquid separation unit 2a has an air passage 23 that communicates with the two adjacent gas-liquid separation cavities 21. Please refer to [link / reference]. Figure 9The separation baffle 22 includes a first end face 220a and a second end face 220b, which are located at opposite ends along the length of the separation baffle 22. An air passage 23 passes through the first end face 220a and the second end face 220b along the length of the separation baffle 22. The thermal management integrated device of this application includes a gas-liquid separator 24, which comprises a separation baffle 22 and a gas-liquid separation chamber 24. The separation baffle 22 is at least partially located between two adjacent gas-liquid separation chambers 21 of the gas-liquid separation chamber 24, and the air passage 23 serves as a channel connecting the two adjacent gas-liquid separation chambers 21. Since the extension direction of the gas passage 23 is consistent with the length direction of the separation baffle 22, and the gas passage 23 passes through the first end face 220a and the second end face 220b of the separation baffle 22 along the length direction of the separation baffle 22, this application can use the gap of the separation baffle 22 passing through the first end face 220a and the second end face 220b on the side of the separation baffle 22 facing the gas passage 23 as the gas passage 23, which can reduce the machining requirements of the gas passage 23 of the separation baffle 22 and reduce the machining difficulty of the gas-liquid separator.

[0047] In some embodiments, the air passage extends through the first end face and the second end face of the separation baffle along its length, so that the air passage can be naturally formed after the separation baffle of the gas-liquid separation section is extruded and formed.

[0048] In some embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 can be connected by an assembly method, such as by inserting or pasting.

[0049] In some embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 are at least partially integral. The separation baffle 22 and the gas-liquid separation chamber 24 can be manufactured into an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc.

[0050] Please see Figure 3 , Figure 4 , Figure 8 and Figure 9 To further reduce the processing difficulty, in some other embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 can be integrally formed. Specifically, the gas-liquid separation chamber 24 has a third end face 240a and a fourth end face 240b, which are located at the two ends of the length direction of the gas-liquid separation chamber 24, respectively. The gas-liquid separation cavity 21 passes through the third end face 240a and the fourth end face 240b along the length direction of the gas-liquid separation chamber 24, and the separation baffle 22 is connected to the gas-liquid separation chamber 24.

[0051] In some embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 are extruded parts, and the separation baffle 22 and the gas-liquid separation chamber 24 can be integrally extruded, which can reduce processing and assembly requirements, thereby reducing processing difficulty. The length direction of the gas-liquid separation chamber 24 is consistent with the length direction of the separation baffle 22; and / or, the extension direction of the gas-liquid separation cavity 21 is consistent with the length direction of the separation baffle 22; and / or, the extension direction of the gas passage 23 is consistent with the length direction of the separation baffle 22. In a specific embodiment, the separation baffle 22 and the gas-liquid separation chamber 24 are integrally extruded, which can reduce processing and assembly requirements, thereby reducing processing difficulty. The extrusion direction of the separation baffle 22 and the gas-liquid separation chamber 24 is consistent with the length direction of the separation baffle 22.

[0052] Please see Figure 7 and Figure 9 In some embodiments, the gas-liquid separation unit 2a has a separation chamber inlet 243 and a separation chamber outlet 244, which are connected to the gas-liquid separation chamber 21. The gas-liquid separator 2 can be connected to other components of the thermal management integrated device through the separation chamber inlet 243 and the separation chamber outlet 244. When the gas-liquid separator 2 is working, the gas-liquid two-phase refrigerant enters through the separation chamber inlet 243, and the gas-liquid two-phase refrigerant is separated by the gas-liquid separation unit 2a. Then, the gaseous refrigerant is discharged from the separation chamber outlet 244 to other components connected to it. In a specific embodiment, the separation chamber inlet 243 and the separation chamber outlet 244 are located in the gas-liquid separation chamber 24.

[0053] Please see Figure 3 , Figure 4 , Figures 7 to 9 In some embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 are integrally extruded. In this case, the opening of the gas-liquid separation chamber 24 is sealed by a cover plate 2c and a sealing plate 2d. Specifically, the gas-liquid separation section 2a also includes a cover plate 2c and a sealing plate 2d, which are connected to the gas-liquid separation chamber 24. The gas-liquid separation chamber 24 has a first port 241 and a second port 242, which are located at opposite ends of the length of the gas-liquid separation chamber 24. One of the cover plate 2c and the sealing plate 2d seals the first port 241, and the other of the cover plate 2c and the sealing plate 2d seals the second port 242.

[0054] Please see Figure 3 , Figure 4 , Figure 8 and Figure 9In some embodiments, the gas-liquid separation section 2a includes at least two separation baffles 22, with adjacent separation baffles 22 arranged alternately; this causes adjacent gas passages 23 to be arranged alternately, and the flow direction of the fluid in each gas-liquid separation chamber 21 is approximately S-shaped. In some embodiments, the gas-liquid separation chamber 24 includes a first wall portion 2401 and a second wall portion 2402. One of the two adjacent separation baffles 22 is connected to the first wall portion 2401 and extends from the first wall portion 2401 toward a side closer to the second wall portion 2402, and the other of the two adjacent separation baffles 22 is connected to the second wall portion 2402 and extends from the second wall portion 2402 toward a side closer to the first wall portion 2401. In some embodiments, the gas-liquid separation chamber 24 is connected to the compressor housing portion 31, which is cylindrical, and the first wall portion 2401 and the second wall portion 2402 are arranged radially along the compressor housing portion 31. The staggered arrangement of the separation baffles 22 can make the flow direction of the fluid as it passes through each gas-liquid separation chamber 21 approximately S-shaped, and cause it to collide with the separation baffles 22 when it passes through them, thus achieving inertial separation and improving the liquid separation efficiency.

[0055] Please see Figure 8 The gas-liquid separation section 2a includes N separation baffles 22 and N+1 gas-liquid separation chambers 21, where N is a non-zero natural number. In one specific embodiment, the gas-liquid separation section 2a includes three separation baffles 22, namely a first baffle 22a, a second baffle 22b, and a third baffle 22c arranged along the fluid flow direction. The three separation baffles 22 divide the interior of the gas-liquid separation section 2a into a first gas-liquid separation chamber 21a, a second gas-liquid separation chamber 21b, a third gas-liquid separation chamber 21c, and a fourth gas-liquid separation chamber 21d arranged along the fluid flow direction. Each separation baffle 22 of the gas-liquid separation section 2a has an air passage 23 at its end to connect two adjacent gas-liquid separation chambers 21. The adjacent air passages 23 are arranged in an alternating pattern, and the fluid flow direction in each gas-liquid separation chamber 21 is approximately S-shaped, as shown in the figure. Figure 8 , Figure 9 The arrows inside the gas-liquid separation section 2a indicate the direction of the separation.

[0056] Please see Figure 3 , Figure 4 , Figure 8 and Figure 9 In some embodiments, please refer to Figure 8 and Figure 9To further improve the liquid separation efficiency, in some embodiments, one side of the separation baffle 22 is connected to the gas-liquid separation chamber 24, and the other side of the separation baffle 22 extends towards the gas passage 23. The gas-liquid separation section 2a also includes a baffle 220, which is connected to the side of the separation baffle 22 facing the gas passage 23. The length direction of the baffle 220 is consistent with the length direction of the separation baffle 22, and the baffle 220 and the separation baffle 22 are at least partially integral. The baffle 220 and the separation baffle 22 can be processed into an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. In one specific embodiment, the baffle 220 and the separation baffle 22 are integrally extruded, which can reduce processing and assembly requirements, thereby reducing processing difficulty. The extrusion direction of the baffle 220 and the separation baffle 22 is consistent with the length direction of the separation baffle 22.

[0057] Please see Figure 8 In some embodiments, the gas passage 23 has a gas inlet 231 and a gas outlet 232. The baffle 220 includes a baffle surface 2201, which is located on the side of the baffle 220 facing the gas inlet 231. The side of the baffle 220 away from the separation baffle 22 bends and extends towards the side of the gas passage 23 with the gas inlet 231. In some embodiments, the gas inlet 231 and the gas outlet 232 are arranged along the flow direction of the fluid, which is a gas-liquid two-phase refrigerant. The flow direction of the fluid is shown in the attached figure. Figure 9 As indicated by the arrow in the gas-liquid separation section 2a, the refrigerant in both gas and liquid phases generates local vortices when passing through the baffle 220, which can improve the liquid separation efficiency and achieve the effects of collision inertial force separation and vortex centrifugal force separation.

[0058] In some specific embodiments, the turbulence surface 2201 is an arc-shaped surface. When the turbulence surface 2201 is arc-shaped, local vortices are generated when the gas and liquid phases pass through it, which can improve the liquid separation efficiency and achieve the effects of separation by collisional inertial force and vortex centrifugal force. In one specific embodiment, the turbulence plate 220 is an arc-shaped plate with arc-shaped surfaces on both sides. Of course, in other embodiments, the turbulence surface 2201 of the turbulence plate 220 can also be an arc-shaped surface, while the other side is a flat surface.

[0059] Please see Figure 3 , Figure 7 and Figure 12In some embodiments, the gas-liquid separation section 2a further includes a partition baffle 2g located in the gas-liquid separation chamber 21 and connected to the gas-liquid separation chamber 24. The gas-liquid separation chamber 21 includes a first partition chamber 210a and a second partition chamber 210b, which are arranged along the length of the gas-liquid separation chamber 24. The partition baffle 2g is located between the first partition chamber 210a and the second partition chamber 210b. The gas-liquid separation section 2a also includes a partition channel 210c communicating with the first partition chamber 210a and the second partition chamber 210b. In a specific embodiment, the separating channel 210c is located on the side of the separating baffle 2g facing the turbulence surface 2201. The gas and liquid refrigerant collide with the separating baffle 22 arranged crosswise in the gas-liquid separation chamber 21 and generate vortices, realizing the separation of inertial force and centrifugal force. The separated liquid refrigerant drips through the separating channel 210c into the second separating chamber 210b near the bottom of the gas-liquid separation section 2a under the action of gravity, thus realizing gas-liquid separation.

[0060] Please see Figure 3 and Figure 6 In some embodiments, the gas-liquid separator 2 further includes a drying component 2f, which includes a drying chamber 2n. The drying chamber 2n is at least partially located in the gas-liquid separation chamber 21. The drying chamber 2n has a drying chamber 2p and a venting groove 2q, which communicates with the drying chamber 2p and the gas-liquid separation chamber 21. In some embodiments, the drying component 2f includes a desiccant 2m, which is located in the drying chamber 2p. The desiccant 2m can be loaded into the drying chamber 2n of the drying component 2f and communicated with the gas-liquid separation chamber 21 through the venting groove 2q. By arranging the desiccant 2m in the drying chamber 2n, water molecules in the refrigerant can be absorbed.

[0061] In some other embodiments, the desiccant 2m can also be placed directly in the gas-liquid separation chamber 21, with at least a portion of the desiccant 2m located in the gas-liquid separation chamber 21, and the desiccant 2m can absorb water molecules in the refrigerant.

[0062] Please see Figure 3 and Figure 6 In some embodiments, the drying assembly 2f is connected to at least one of the cover plate 2c and the sealing plate 2d, at least one of the cover plate 2c and the sealing plate 2d having a mounting groove 2j. The drying assembly 2f also includes an end cap 2t that seals the mounting groove 2j. In some specific embodiments, the drying assembly 2f is detachably connected to the cover plate 2c to facilitate the replacement of the desiccant 2m in the drying chamber 2n.

[0063] Please see Figure 3 , Figure 4 and Figure 6In some embodiments, to achieve the oil return effect, the gas-liquid separator 2 further includes an oil return section 2b, which has an inlet oil return chamber 25.

[0071] To reduce the occurrence of liquid carryover during intake, this application proposes an integrated thermal management device. Please refer to [link to relevant documentation]. Figures 1 to 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the thermal management integrated device includes a gas-liquid separator 2, see [link to relevant documentation]. Figure 6The gas-liquid separator 2 includes an oil return section 2b, please refer to [link / reference]. Figure 6 The oil return section 2b has an intake oil return chamber 25 and an exhaust oil return chamber 26. The intake oil return chamber 25 includes an oil return storage chamber 251. The gas-liquid separator 2 includes a sealing plate 2d, which is located at one end of the oil return section 2b near the oil return storage chamber 251. The sealing plate 2d blocks the oil return storage chamber 251. Please refer to [link / reference]. Figure 6 The oil return section 2b includes an oil return baffle 24c, which includes a baffle portion 241c and a venting portion 242c. The baffle portion 241c is connected to the sealing plate 2d and is located at least partially between the oil return storage chamber 251 and the exhaust oil return chamber 26. The venting portion 242c has a first connecting port 20a, which communicates with the intake oil return chamber 25 and the exhaust oil return chamber 26.

In this application, the oil return section 2b of the thermal management integrated device has an inlet oil return chamber 25 and an exhaust oil return chamber 26. The inlet oil return chamber 25 includes an oil return storage chamber 251. The oil return section 2b includes an oil return baffle 24c and a sealing plate 2d. The oil return baffle 24c includes a baffle portion 241c and a venting portion 242c. The first connecting port 20a of the venting portion 242c is connected to the inlet oil return chamber 25 and the exhaust oil return chamber 26. The venting portion 242c is further away from the sealing plate 2d than the baffle portion 241c, and the baffle portion 241c is connected to the sealing plate 2d. The baffle portion 241c is at least partially located between the oil return storage chamber 251 and the exhaust oil return chamber 26. By using the baffle portion 241c to separate the oil return storage chamber 251 and the exhaust oil return chamber 26, the occurrence of liquid carryover during air intake can be reduced.

[0072] Please see Figure 6 In some embodiments, the first connecting port 20a is located at the end of the vent 242c facing away from the sealing plate 2d. In this embodiment, the first connecting port 20a is located at a high position away from the return oil storage chamber 251, which can better separate the return oil storage chamber 251 and the exhaust return oil chamber 26, and reduce the phenomenon of air intake and liquid carry-over caused by the rise of the return oil level in the return oil storage chamber 251.

[0073] Please see Figures 1 to 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the oil return section 2b includes a first oil return chamber 24a, and the intake oil return chamber 25 is located in the first oil return chamber 24a. Please refer to [link to relevant documentation]. Figure 4The first oil return chamber 24a has an oil return hole 2i, which is connected to the oil return storage chamber 251. The oil return section 2b includes a second oil return chamber 24b, and an exhaust oil return chamber 26 is located in the second oil return chamber 24b. The second oil return chamber 24b has an exhaust outlet 245, which is connected to the exhaust oil return chamber 26. By arranging the oil return hole 2i and the exhaust outlet 245 in the first oil return chamber 24a and the second oil return chamber 24b respectively, and using the oil return baffle 24c to separate the first oil return chamber 24a and the second oil return chamber 24b, the phenomenon of air intake and liquid carryover caused by the rise of the oil return level in the oil return storage chamber 251 can be reduced.

[0074] In some embodiments, the oil return baffle 24c is at least partially integral with at least one of the first oil return chamber 24a and the second oil return chamber 24b; in some embodiments, the extending direction of the intake oil return chamber 25 and the extending direction of the exhaust oil return chamber 26 are both consistent with the length direction of the oil return portion 2b, and the oil return baffle 24c and at least one of the first oil return chamber 24a and the second oil return chamber 24b can be processed into an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc.

[0075] Of course, in some other embodiments, the oil return baffle 24c can also be assembled and connected with the first oil return chamber 24a or the second oil return chamber 24b.

[0076] In one specific embodiment, the length direction of at least one of the first oil return chamber 24a and the second oil return chamber 24b is consistent with the length direction of the oil return baffle 24c. In this case, the oil return baffle 24c and at least one of the first oil return chamber 24a and the second oil return chamber 24b can be integrally extruded, allowing for integrated extrusion molding of the oil return baffle 24c and at least one of the first oil return chamber 24a and the second oil return chamber 24b, reducing processing and assembly requirements and thus lowering processing difficulty. Specifically, when the oil return baffle 24c and the first oil return chamber 24a and the second oil return chamber 24b are extruded simultaneously, the extrusion direction of the oil return baffle 24c and the first oil return chamber 24a and the second oil return chamber 24b is consistent with the length direction of the oil return portion 2b. In this case, the baffle portion 241c and the venting portion 242c are at least partially integral.

[0077] Please see Figure 4 , Figure 6 , Figure 8 and Figure 9In some embodiments, the oil return section 2b further includes an intake baffle 250. The intake oil return chamber 25 includes a first oil return chamber 25a and a second oil return chamber 25b. The intake baffle 250 is at least partially located between the first oil return chamber 25a and the second oil return chamber 25b. The intake baffle 250 has a second connecting port 20b, which communicates with the first oil return chamber 25a and the second oil return chamber 25b. The second connecting port 20b is located at one end of the intake baffle 250 facing the sealing plate 2d. In a specific embodiment, the second connecting port 20b is located in or near the oil return storage chamber 251. Through the intake baffle 250, the gaseous refrigerant can flow more through the oil return storage chamber 251 after passing through the second connecting port 20b, which is beneficial for bringing more of the oil stored in the oil return storage chamber 251 back to the suction chamber of the compression unit 3.

[0078] Please see Figure 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the intake baffle 250 and the first oil return chamber 24a are at least partially integral; in other embodiments, the intake baffle 250 and the first oil return chamber 24a can be manufactured as an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. Of course, in other embodiments, they can also be assembled together. In a specific embodiment, the length direction of the first oil return chamber 24a is consistent with the length direction of the intake baffle 250. In this case, the intake baffle 250 and the first oil return chamber 24a can be integrally extruded, allowing them to be extruded as a single unit, reducing processing and assembly requirements, and thus reducing processing difficulty. Specifically, when the intake baffle 250 and the first oil return chamber 24a are extruded together, the extrusion direction of the intake baffle 250 and the first oil return chamber 24a is consistent with the length direction of the oil return section 2b.

[0079] In some other embodiments, the length direction of the oil return baffle 24c is consistent with the length direction of the air intake baffle 250. Furthermore, the oil return baffle 24c, the air intake baffle 250, and the first oil return chamber 24a and the second oil return chamber 24b can be integrally extruded, allowing for integrated extrusion molding of the oil return baffle 24c, the air intake baffle 250, and the first oil return chamber 24a and the second oil return chamber 24b. This reduces processing and assembly requirements and further lowers processing difficulty. Then, the corresponding first connecting port 20a and second connecting port 20b can be machined onto the oil return baffle 24c and the air intake baffle 250.

[0080] Please see Figure 3 , Figure 6 , Figure 8 and Figure 9In some embodiments, the oil return section 2b has an oil return chamber inlet 20c, which is located at one end of the oil return section 2b away from the oil return storage chamber 251, and the oil return chamber inlet 20c is connected to the oil return chamber 25.

The oil return chamber inlet 20c is connected to the gas-liquid separation cavity 21, and the oil return chamber inlet 20c is located at one end of the gas-liquid separation section 2a away from the oil return storage chamber 251. When the gas-liquid separator 2 is working, the gas-liquid two-phase mixed refrigerant enters the gas-liquid separation cavity 21 through the separation cavity inlet 243. The gas-liquid two-phase mixed refrigerant is separated by the gas-liquid separation section 2a, and then the gas phase refrigerant is discharged to the oil return chamber 25 through the separation cavity outlet 244 and the oil return chamber inlet 20c. The gas-liquid separator 2 has an oil return channel 2r, and the gas-liquid separation chamber 21 includes a separation oil storage chamber 211. The oil return channel 2r communicates with the separation oil storage chamber 211 and the oil return storage chamber 251. In some embodiments, the separation oil storage chamber 211 and the oil return storage chamber 251 are connected through the oil return channel 2r. The oil entering the gas-liquid separation section 2a can enter the oil return storage chamber 251 through the oil return channel 2r. When the gaseous refrigerant passes through the inlet oil return chamber 25, it will carry away a portion of the oil stored in the oil return storage chamber 251 and return it to the compression unit 3, thus realizing oil return.

[0081] Please see Figure 3 and Figure 4 In some embodiments, the gas-liquid separator 2 has an oil return groove 2k, an oil return channel 2r located in the oil return groove 2k, and an oil discharge hole 2h in the gas-liquid separation chamber 24.

A part of the oil return groove 2k is located in the first oil return chamber 24a, and another part of the oil return groove 2k is located in the gas-liquid separation chamber 24. The gas-liquid separator 2 also includes an oil return cover plate 2e, which is connected to the first oil return chamber 24a and the gas-liquid separation chamber 24. The oil return cover plate 2e blocks the oil return groove 2k. In one specific embodiment, the first oil return chamber 24a and the gas-liquid separation chamber 24 can be at least partially integrated. In this case, corresponding oil return grooves 2k can be machined in the first oil return chamber 24a and the gas-liquid separation chamber 24, and the oil return channel 2r can be sealed by using the oil return cover plate 2e. When the gaseous refrigerant passes through the oil return storage chamber 251 at the bottom of the first oil return chamber 24a, it carries away a portion of the suction chamber of the oil compression unit 3.

[0082] Please see Figure 3 and Figure 4In some embodiments, the gas-liquid separation chamber 24 and at least one of the first oil return chamber 24a and the second oil return chamber 24b are at least partially integral. In other embodiments, the gas-liquid separation chamber 24 and at least one of the first oil return chamber 24a and the second oil return chamber 24b can be manufactured as an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. Of course, in other embodiments, the gas-liquid separation chamber 24 can also be assembled and connected with the first oil return chamber 24a or the second oil return chamber 24b. In a specific embodiment, the gas-liquid separation chamber 24, the first oil return chamber 24a, and the second oil return chamber 24b are all at least partially integral. In one specific embodiment, the length direction of at least one of the first oil return chamber 24a and the second oil return chamber 24b is consistent with the length direction of the gas-liquid separation chamber 24. In this case, the gas-liquid separation chamber 24 and at least one of the first oil return chamber 24a and the second oil return chamber 24b can be integrally extruded, allowing for integral extrusion molding of the gas-liquid separation chamber 24 and at least one of the first oil return chamber 24a and the second oil return chamber 24b, reducing processing and assembly requirements and thus lowering processing difficulty. Specifically, when the gas-liquid separation chamber 24 and the first oil return chamber 24a and the second oil return chamber 24b are extruded simultaneously, the extrusion direction of the gas-liquid separation chamber 24 and the first oil return chamber 24a and the second oil return chamber 24b is consistent with the length direction of the oil return section 2b.

[0083] Please see Figure 3 and Figure 4 In some embodiments, the gas-liquid separation section 2a further includes a separation baffle 22, and the gas-liquid separation chamber 24 has at least two gas-liquid separation cavities 21. The separation baffle 22 is at least partially located between two adjacent gas-liquid separation cavities 21. The gas-liquid separation section 2a has an air passage 23 that communicates with the two adjacent gas-liquid separation cavities 21. In some embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 are at least partially integral parts. They can be processed into an integral part by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. The length direction of the separation baffle 22 is consistent with the length direction of the gas-liquid separation chamber 24. In this case, the separation baffle 22 and the gas-liquid separation chamber 24 can be integrally extruded parts, which can reduce processing and assembly requirements and thus reduce processing difficulty. Of course, in other embodiments, the separation baffle 22 and the gas-liquid separation chamber 24 can also be assembled and connected.

The exhaust oil return chamber 26 is connected to the exhaust port 245, and the exhaust port 245 is connected to the intake port 31a. The gaseous refrigerant, after gas-liquid separation by the gas-liquid separator 2, enters the compression unit 3 through the intake port 31a, which can reduce the "liquid slugging" phenomenon caused by the inflow of liquid refrigerant into the compression unit 3.

[0085] Please see Figures 1 to 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the thermal management integrated device further includes a flow channel section 11, which has a refrigerant inlet 119a and a refrigerant outlet 119b.

[0088] To achieve a more compact flow channel distribution and facilitate the miniaturization of the integrated thermal management device, this application proposes an integrated thermal management device. Please refer to [link to relevant documentation]. Figure 1 , Figure 10 , Figure 11 , Figure 14 and Figure 17 In some embodiments, the thermal management integrated device includes a flow channel 1, a first heat exchange device 5, and a second heat exchange device 6. The flow channel 1 has a first heat exchange flow channel M and a second heat exchange flow channel N.

The second heat exchange device 6 has a second refrigerant channel 61, and the second heat exchange flow channel N communicates with the second refrigerant channel 61. The flow channel 1 includes a first heat exchange section Pa and a second heat exchange section Pb, which are arranged along a first direction F1. The first heat exchange flow channel M to... A small portion is located in the first flow channel section Pa, and at least a portion of the second heat exchange flow channel N is located in the second heat exchange section Pb; at least one of the first heat exchange section Pa and the second heat exchange section Pb includes the first flow channel section P1 and the second flow channel section P2, the first flow channel section P1 and the second flow channel section P2 are arranged along the second direction F2, the first direction F1 intersects the second direction F2, at least one of the first heat exchange flow channel M and the second heat exchange flow channel N includes the first flow channel T1 and the second flow channel T2, the first flow channel T1 is at least partially located in the first flow channel section P1, and the second flow channel T2 is at least partially located in the second flow channel section P2.

[0089] In this application, the flow channel component 1 of the thermal management integrated device includes a first heat exchange section Pa and a second heat exchange section Pb arranged along a first direction F1. At least one of the first heat exchange section Pa and the second heat exchange section Pb includes a first flow channel section P1 and a second flow channel section P2. At least one of the first heat exchange flow channel M and the second heat exchange flow channel N includes a first flow channel T1 and a second flow channel T2. The first direction F1 intersects with the second direction F2. At least portions of the first heat exchange flow channel M and the second heat exchange flow channel N are respectively arranged in the first flow channel section Pa and the second heat exchange section Pb arranged along the first direction F1. At least portions of the first flow channel T1 and the second flow channel T2 are respectively arranged in the first flow channel section P1 and the second flow channel section P2 arranged along the second direction F2. This makes the first heat exchange flow channel M and the second heat exchange flow channel N of the flow channel component 1 more compactly distributed, which is beneficial for the miniaturization of the thermal management integrated device.

[0090] Wherein, the intersection of the first direction F1 and the second direction F2 means that the two directions are not parallel and do not coincide in the two-dimensional plane. In a specific embodiment, the first direction F1 and the second direction F2 are perpendicular.

[0091] Please see Figure 10 , Figure 11 and Figure 14 In order to make the flow channel distribution more compact, in some embodiments, the first heat exchange flow channel M and the second heat exchange flow channel N are at least partially parallel; and / or, the first flow channel T1 and the second flow channel T2 are at least partially parallel; the use of flow channels arranged at least partially parallel can further make the flow channel distribution more compact, which is conducive to the miniaturization of the thermal management integrated device.

[0092] Please see Figure 10 , Figure 11 and Figure 14 In some embodiments, taking the first heat exchange channel M as a single channel and the second heat exchange channel N as a dual channel as an example, the second heat exchange channel N includes a first flow channel T1 and a second flow channel T2 as an example. In some specific embodiments, parts of the first flow channel T1, the second flow channel T2, and the first heat exchange channel M are parallel, or all of them are parallel. Of course, parts of all three can be parallel, or all three can remain parallel. In other embodiments, taking both the first heat exchange channel M and the second heat exchange channel N as dual channels as an example, in some embodiments, two of the four channels are parallel, three channels are parallel, or all four channels are parallel.

[0093] Please see Figure 10 and Figure 14In some embodiments, at least one of the first heat exchange section Pa and the second heat exchange section Pb includes a channel heat exchange section R, which is at least partially located between the first heat exchange channel M and the second heat exchange channel N. This allows the heat exchange medium flowing in the first heat exchange channel M to exchange heat with the heat exchange medium flowing in the second heat exchange channel N through the channel heat exchange section R, thereby realizing the function of a regenerator. In a specific embodiment, the first heat exchange channel M, the channel heat exchange section R, and the second heat exchange channel N are arranged along a first direction F1.

At least two of the first heat exchange channel M, the first flow channel T1, and the second flow channel T2 are parallel. In some specific embodiments, the first heat exchange channel M is parallel to both the first flow channel T1 and the second flow channel T2. Using three parallel flow channels allows for a more compact channel layout. Of course, having only two of them parallel can also achieve a more compact channel layout to some extent. Please refer to [link to relevant documentation]. Figure 14 In some embodiments, the second heat exchange channel N includes a fourth channel 110d and a fifth channel 110e, that is, the first channel T1 is the fourth channel 110d, the second channel T2 is the fifth channel 110e, and the first heat exchange channel M is the second channel 110b.

[0095] Please see Figure 10 and Figure 14 The heat exchange section R is at least partially located between the first heat exchange channel M and the first flow channel T1, and at least partially located between the first heat exchange channel M and the second flow channel T2. In some embodiments, the heat exchange section R is provided between the first flow channel T1, the second flow channel T2, and the first heat exchange channel M, so that the first heat exchange channel M can exchange heat with the heat exchange medium flowing in the first flow channel T1 and the second flow channel T2 through the heat exchange section R, thereby realizing the function of a regenerator.

In one specific embodiment, the first flow channel T1 and the second flow channel T2 are arranged along the second direction F2, so that the first flow channel T1 and the second flow channel T2 can be arranged side by side on one side of the first heat exchange channel M, further reducing the width dimension of the flow channel and making the overall structure more compact.

[0117] To improve the heat dissipation of the controller unit, this application proposes an integrated thermal management device. Please refer to [link to relevant documentation]. Figures 1 to 6 In some embodiments, the thermal management integrated device includes a gas-liquid separator 2 and a control unit 4. The gas-liquid separator 2 has a gas-liquid separation chamber 21 and a gas-liquid separation housing 200. The gas-liquid separation chamber 21 is disposed in the gas-liquid separation housing 200. The control unit 4 includes a controller housing 41 and a heat dissipation part 411. The heat dissipation part 411 is at least partially attached to the gas-liquid separation housing 200, and / or the heat dissipation part 411 and the gas-liquid separation housing 200 are at least partially integral. The thermal management integrated device of this application includes a gas-liquid separator 2 and a control unit 4. The gas-liquid separator 2 has a gas-liquid separation chamber 21 and a gas-liquid separation housing 200. The gas-liquid separation chamber 21 is located in the gas-liquid separation housing 200. The control unit 4 includes a controller housing 41. The heat dissipation part 411 of the controller housing 41 is at least partially attached to the gas-liquid separation housing 200, and / or the heat dissipation part 411 and the gas-liquid separation housing 200 are at least partially integral. When the gas-liquid separator 2 is working, the low-temperature refrigerant flowing in the gas-liquid separation chamber 21 can cool the controller unit, thereby improving the heat dissipation effect on the controller unit 4.

[0118] Please see Figure 3 , Figure 6 and Figure 16In some embodiments, the control unit 4 further includes a controller body 42, which is connected to a controller housing portion 41, and the controller housing portion 41 is connected to a gas-liquid separation housing portion 200. The gas-liquid separation housing portion 200 includes a first sidewall portion 2001, which is located on the side of the gas-liquid separator 2 facing the heat dissipation portion 411. The heat dissipation portion 411 is at least partially in contact with the first sidewall portion 2001. In some specific embodiments, the heat dissipation portion 411 and the first sidewall portion 2001 can be kept in full contact to increase the heat exchange area and facilitate heat dissipation. The heat dissipation portion 411 is a heat-conducting element. When the gas-liquid separator 2 is working, the heat dissipation portion 411, which is at least partially in contact with the first sidewall portion 2001, can exchange heat with the low-temperature refrigerant flowing in the gas-liquid separation chamber 21, thereby achieving cooling of the controller body 42. In some embodiments, the controller body 42 and the heat dissipation portion 411 are directly in contact, which is more conducive to heat dissipation. In some other embodiments, the controller body 42 and the heat dissipation part 411 may not be attached, and the two may indirectly dissipate heat through other heat exchange media. The controller housing part 41 or the heat dissipation part 411 may be assembled and connected to the gas-liquid separation housing part 200; of course, in some other embodiments, the controller housing part 41 or the heat dissipation part 411 and the gas-liquid separation housing part 200 may also be at least partially integral, for example, processed into an integral part by bonding, welding, casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc.

[0119] Please see Figure 3 , Figure 6 and Figure 16 In some embodiments, the controller body 42 and the heat dissipation part 411 are at least partially attached; in some specific embodiments, the controller body 42 and the heat dissipation part 411 may be partially attached or in full contact, which is more conducive to heat exchange, thereby improving the heat dissipation effect and ensuring the reliability of the operation of the control unit 4.

[0120] In this embodiment, the controller body 42 can be located in an open space, in which case the heat dissipation part 411 is at least partially attached to the controller body 411 for heat dissipation. Alternatively, in other embodiments, it can be located in a relatively enclosed space. Specifically, in some embodiments, the controller housing 41 has a controller mounting cavity 410, and the controller body 42 is at least partially located in the controller mounting cavity 410. The controller housing 41 also includes an outer shell 412, which is connected to the heat dissipation part 411, and the controller mounting cavity 410 is located between the outer shell 412 and the heat dissipation part 411. The heat dissipation part 411 and the outer shell 412 can be at least partially integral, for example, by bonding, welding, casting, forging, stamping, extrusion, metal injection molding, or metal powder metallurgy. Alternatively, in other embodiments, the heat dissipation part 411 can be assembled and connected to the outer shell 412.

[0121] In some embodiments, the heat dissipation effect is better when the controller body 42 is located in the controller mounting cavity 410 and is at least partially in contact with the heat dissipation part 411. Of course, in other embodiments, the controller body 42 and the heat dissipation part 411 may not be in contact. Even if the controller body 42 and the heat dissipation part 411 are not in contact, since the controller body 42 is built into the controller mounting cavity 410, the heat dissipation part 411 and the air in the controller mounting cavity 410 can exchange heat, thereby cooling the controller body 42 to a certain extent.

[0122] Please see Figure 2 and Figure 16 In some embodiments, the heat dissipation part 411 includes a first heat-conducting wall 411a, and the first side wall part 2001 includes a second heat-conducting wall 2001a. The first heat-conducting wall 411a and the second heat-conducting wall 2001a are at least partially attached to each other, and the first heat-conducting wall 411a and the second heat-conducting wall 2001a are at least partially parallel. In some embodiments, the portion of the first heat-conducting wall 411a and the second heat-conducting wall 2001a that is parallel and attached can be a planar structure, which is more conducive to the contact between the two and thus improves the heat dissipation effect.

[0123] Please see Figure 2 and Figure 16 In some embodiments, the heat dissipation part 411 includes a third heat-conducting wall 411b, and the controller body 42 includes a fourth heat-conducting wall 42a. The third heat-conducting wall 411b and the fourth heat-conducting wall 42a are at least partially attached and at least partially parallel. In some embodiments, the portion of the third heat-conducting wall 411b and the fourth heat-conducting wall 42a that is parallel and attached can be a planar structure, which is more conducive to the contact between the two and thus improves the heat dissipation effect. In addition, adopting a planar structure can simplify the overall structure and facilitate processing and assembly. The first heat-conducting wall 411a and the third heat-conducting wall 411b are located on both sides of the thickness direction of the heat dissipation part 411.

[0124] Please see Figure 4 and Figure 6In some embodiments, the thermal management integrated device further includes a compression unit 3, which includes a compressor housing portion 31 and a motor mounting housing portion 311. The motor mounting housing portion 311 is at least partially attached to the gas-liquid separation housing portion 200. The compressor housing portion 31 has an intake port 31a located in the motor mounting housing portion 311 and communicating with the gas-liquid separation chamber 21. In some embodiments, the compression unit 3 further includes a compressor core portion 30, which is electrically connected to the controller body 42. The compressor housing portion 31 has a mounting cavity 310, and the compressor core portion 30 is at least partially located in the mounting cavity 310. In a specific embodiment, the compressor core portion 30 includes a motor (not shown in the figures), which is electrically connected to the controller body 42 and is at least partially mounted in the inner cavity of the motor mounting housing portion 311. On the one hand, the low-temperature refrigerant flowing through the gas-liquid separator 2 can cool the motor, thereby achieving localized cooling of the motor and improving its operating efficiency. On the other hand, the suction port 31a is located in the motor mounting housing 311 and is connected to the mounting cavity 310. When the low-temperature refrigerant enters through the suction port 31a, it will flow through the motor and cool it.

[0125] Please see Figure 3 and Figure 6 In some embodiments, the gas-liquid separator housing 200 and the compressor housing 31 are connected. The gas-liquid separator housing 200 includes a second sidewall 2002 located on the side of the gas-liquid separator 2 facing away from the control unit 4. The second sidewall 2002 is at least partially attached to the motor mounting housing 311. When the gas-liquid separator 2 is working, the motor mounting housing 311, which is at least partially attached to the second sidewall 2002, can exchange heat with the low-temperature refrigerant flowing through the gas-liquid separator chamber 21, thereby cooling the motor installed inside the motor mounting housing 311. The gas-liquid separator housing 200 and the compressor housing 31 can be assembled and connected, for example, by screw connection. In other embodiments, the controller housing 41 and the gas-liquid separator housing 200 can also be at least partially integrated, for example, by bonding, welding, casting, forging, stamping, extrusion, metal injection molding, or metal powder metallurgy.

[0126] Please see Figure 1 and Figure 4In some embodiments, the gas-liquid separator housing 200 and the compressor housing 31 are at least partially integral. The gas-liquid separator housing 200 and the compressor housing 31 can be manufactured into an integral part through casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc., which can reduce the assembly difficulty of the gas-liquid separator 2 and the compression unit 3. In a specific embodiment, the gas-liquid separator housing 200 and the compressor housing 31 are integrally extruded, which reduces processing and assembly requirements, thereby reducing processing difficulty.

[0127] Please see Figure 4 In some embodiments, the length direction of the gas-liquid separator housing 200 is consistent with the length direction of the compressor housing 31, and both the gas-liquid separator housing 200 and the compressor housing 31 are extruded parts. The fact that the gas-liquid separator housing 200 and the compressor housing 31 are consistent in length direction allows them to be extruded as a single unit, reducing processing and assembly requirements and thus lowering processing difficulty.

[0128] Please see Figure 4 In some embodiments, to further reduce assembly difficulty, the flow channel portion 11 is integrated with the gas-liquid separation housing portion 200 and the compressor housing portion 31. Specifically, in some embodiments, the thermal management integrated device further includes a flow channel component 1, which includes the flow channel portion 11, and at least one of the gas-liquid separation housing portion 200 and the compressor housing portion 31 is connected to the flow channel portion 11. In some embodiments, at least one of the gas-liquid separation housing portion 200 and the compressor housing portion 31 can be assembled and connected to the flow channel portion 11.

[0129] In other embodiments, at least one of the gas-liquid separator housing 200 and the compressor housing 31 is at least partially integral with the flow channel 11. The gas-liquid separator housing 200 and the compressor housing 31, along with the flow channel 11, can be manufactured as an integral part through casting, forging, stamping, extrusion, metal injection molding, or metal powder metallurgy. In one specific embodiment, the flow channel 11 is integrally extruded with the gas-liquid separator housing 200 and the compressor housing 31, which reduces processing and assembly requirements, thereby lowering processing difficulty.

[0130] Please see Figures 1 to 4In some embodiments, to further improve integration, the thermal management integrated device further includes at least one of a compression unit 3, a first heat exchange device 5, a second heat exchange device 6, a first valve assembly 7, and a second valve assembly 8. At least one of these components is connected to the flow channel portion 11. In some specific embodiments, the compression unit 3 is located on one side of the flow channel portion 11, and the first heat exchange device 5, the second heat exchange device 6, the first valve assembly 7, and the second valve assembly 8 are located on the other side. The first heat exchange device 5 and the second heat exchange device 6 are arranged alternately, which facilitates component installation. In some embodiments, the flow channel component 1 also includes a connecting unit 9, which serves as a connector between flow channels or between flow channels and other thermal management system components. Using the connecting unit 9 can shorten the length of the flow channel, reducing ineffective heat exchange to a certain extent. The overall structure is more compact, lighter, and more integrated, saving lateral space and making it suitable for long, narrow spaces.
