Technical Field

[0001] This application relates to the field of fluid control technology, and more particularly to unidirectional components and compression integration modules for vehicle thermal management. Background Technology

[0002] In certain operating conditions, refrigerant enters the chamber through the channel in related thermal management components. However, when no refrigerant flows into the chamber through the channel, the refrigerant in the chamber cannot flow back into the channel. One-way valves can be installed in the channel or at the chamber inlet, but these valves are complex and bulky, hindering the integration of thermal management components. Summary of the Invention

[0018] 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.

[0020] According to a specific embodiment of the unidirectional component 3 of this application, such as Figures 1 to 5 As shown, the one-way component 3 includes a housing 31, a valve plate 32, and a limiting part 33. The housing 31 includes a main body 312, a cover 311, and a partition 313. The main body 312 has a first opening 304, a second opening 305, a first cavity 301, and a second cavity 303. The first opening 304 communicates with the first cavity 301, and the second opening 305 communicates with the second cavity 303. The partition 313 is located between the first cavity 301 and the second cavity 303, and the partition 313 has a connecting hole 302 that communicates with the first cavity 301. The main body 312 is a hollow cylindrical structure. The cover 311 is located on one side of the length direction of the main body 312 and blocks one end of the main body 312. The first opening 304 and the second opening 305 are both located on the other side of the length direction of the main body 312. Both the valve plate portion 32 and the limiting portion 33 are located in the second cavity 303, and are fixed to the housing portion 31. The valve plate portion 32 includes a first tongue portion 322, and the limiting portion 33 includes a second tongue portion 332. The first tongue portion 322 is at least partially located between the partition portion 313 and the second tongue portion 332. The end portion of the first tongue portion 322 is aligned with one side opening of the connecting hole 302. The end portion of the first tongue portion 322 can move within the gap between the partition portion 313 and the second tongue portion 332. The first tongue portion 322 can cause the connecting hole 302 to be closed or open to the second cavity 303.

[0021] The unidirectional component 3 of this application has a connecting hole 302 in the partition 313 that communicates with the first cavity 301, and a first tongue 322 that can cut off or connect the connecting hole 302 with the second cavity 303, thereby realizing the function of connecting and cutting off the first cavity 301 and the second cavity 303; its main body 312 is a hollow cylindrical structure, and the first opening 304 and the second opening 305 are both located on the same side of the main body 312, which is conducive to the miniaturization of the unidirectional component 3. The unidirectional component 3 has a simple structure and is easy to integrate.

[0022] On the other hand, since the first port 304 and the second port 305 are both located on the same side of the main body 312, it is advantageous to arrange the components that cooperate with the first port 304 and the components that cooperate with the second port 305 on the same side of the unidirectional component 3, or to integrate the components that cooperate with the first port 304 and the components that cooperate with the second port 305 together. The application of the unidirectional component 3 in the integration scheme is beneficial to the miniaturization of the integrated module.

[0023] In some embodiments, the main body 312, the cover 311, and the partition 313 are respectively formed, and then assembled and fixed together. In some other possible embodiments, at least two of the main body 312, the cover 311, and the partition 313 are integral parts. For example, the main body 312 and the cover 311 are integral parts, and the partition 313 is separately assembled and fixed together; the main body 312 and the partition 313 are integral parts, and the cover 311 is separately assembled and fixed together; the partition 313 and the cover 311 are integral parts, and the main body 312 is separately assembled and fixed together; or the main body 312, the cover 311, and the partition 313 are integral parts.

[0024] The partition 313 is located between the first cavity 301 and the second cavity 303. In this embodiment, refer to... Figure 5The partition 313 includes a first wall 315 and a second wall 314. The first wall 315 extends along the length of the main body 312, and its extension length is less than that of the main body 312. The second wall 314 extends in a direction perpendicular to the length of the main body 312. The first wall 315 is sealed to the inner wall of the main body 312 at two points on both sides in its width direction. The second wall 314 is sealed to both the first wall 315 and the inner wall of the main body 312. Thus, the partition 313 divides the inner cavity of the main body 312 into a first cavity 301 and a second cavity 303. A portion of the first cavity 301 is located between the first wall 315 and the cover 311, and another portion is located between the second wall 314 and the cover 311. The second cavity 303 and a portion of the first cavity 301 are located on different sides in the thickness direction of the first wall 315, and the second cavity 303 and another portion of the first cavity 301 are located on different sides in the thickness direction of the second wall 314. In this embodiment, the connecting hole 302 is disposed on the second wall 314, and the connecting hole 302 penetrates both sides of the second wall 314 in the thickness direction. In other possible embodiments, the connecting hole 302 may also be disposed on the first wall 315, and the connecting hole 302 penetrates both sides of the first wall 315 in the thickness direction.

[0025] In some embodiments, the first wall 315 and the second wall 314 are integral, with the second wall 314 extending outward from the extended end of the first wall 315. Optionally, the cross-section of the partition 313 is generally L-shaped. In some other possible embodiments, the first wall 315 and the second wall 314 are formed separately and then assembled and fixed together, or assembled and fixed separately to the main body 312.

[0026] In this embodiment, refer to Figure 2 The sidewall surrounding the first opening 304 includes a portion of the main body 312 and a first wall 315, and the sidewall surrounding the second opening 305 includes another portion of the main body 312 and a first wall 315. The first opening 304 and the second opening 305 are located on opposite sides of the thickness direction of the first wall 315 and are isolated from each other at the first wall 315. The end faces of the main body 312 and the first wall 315 away from the cover 311 are both planes, and are flush with each other. This arrangement makes it easier for the unidirectional component 3 to fit and connect with other components, facilitating integration. The plane-to-plane fit ensures high connection reliability. The second opening 305 and the first opening 304 are relatively large, resulting in low flow resistance. The structure of the main body 312 is relatively simple, and the manufacturing process is straightforward.

[0027] In one possible embodiment, a bottom cover is provided on the side of the main body 312 away from the cover 311, and the bottom cover is sealed to the other side of the main body 312. A first opening 304 and a second opening 305 are provided on the bottom cover, and both the first opening 304 and the second opening 305 penetrate through both sides of the bottom cover along the thickness direction. The end surface of the bottom cover away from the top cover is flat. This arrangement makes it easier for the unidirectional component 3 to fit and connect with other components, and the contact area is large, which is beneficial for integration and has high connection reliability.

[0028] In one possible embodiment, the end face of the main body 312 away from the cover 311 is farther from the cover 311 than the end face of the first wall 315 away from the cover 311; or, the end face of the main body 312 away from the cover 311 is closer to the cover 311 than the end face of the first wall 315 away from the cover 311. Before the unidirectional component 3 is assembled with other components, the first port 304 is connected to the second port 305, but after assembly with other components, the first port 304 and the second port 305 are isolated from each other at the first wall 315.

[0029] In this application, the shell portion 31, the valve plate portion 32, and the limiting portion 33 together realize the function of a one-way valve. The first tongue portion 322 is an elastic body, and the partition portion 313 and the second tongue portion 332 are rigid bodies. The second tongue portion 332 and the partition portion 313 work together to limit the deformation of the first tongue portion 322. In the first state, the first tongue portion 322 is in contact with the partition portion 313 and blocks one side opening of the connecting hole 302, thus closing the connecting hole 302 and the second cavity 303. In the second state, the first tongue portion 322 is located in the gap between the second tongue portion 332 and the partition portion 313, or the first tongue portion 322 is in contact with the second tongue portion 332, and there is a gap between the first tongue portion 322 and the partition portion 313, thus connecting the connecting hole 302 and the second cavity 303.

[0030] Optionally, the first state is the natural state, i.e., the state without external force applied, and the second state is the deformed state, i.e., the state with external force applied; or, the first state is the morphological state with a smaller deformation, and the second state is the deformed state with a larger deformation. The elasticity of the elastomer ensures the reliability of sealing the connecting hole 302 in the first state.

[0031] It's important to understand that an elastic body is an object that can deform under external force but returns to its original shape when the force is removed. Elastic bodies allow for a certain degree of deformation, and this deformation is reversible.

[0032] A rigid body is an object whose shape and size remain unchanged when subjected to external forces. Regardless of the force applied, a rigid body will not deform; its shape and dimensions remain constant. An absolutely rigid body does not actually exist; it is merely an ideal model. This is because any object deforms to some extent after being subjected to forces. If the degree of deformation is extremely small relative to the object's geometric dimensions, it can be ignored when studying the object's motion. In practical engineering, when the deformation of an object is very small relative to its overall dimensions, it can be treated as a rigid body. Treating many solids as rigid bodies generally yields results with sufficient accuracy in engineering.

[0033] It is understandable that elastic bodies and rigid bodies can be made of the same material; for example, a thin metal sheet is an elastic body, and a metal block is a rigid body.

[0034] The valve plate portion 32 and the limiting portion 33 are respectively fixed to the housing portion 31. In this embodiment, refer to... Figures 3 to 5 The valve plate portion 32 and the limiting portion 33 are respectively fixed to the partition portion 313. Specifically, the valve plate portion 32 and the limiting portion 33 are respectively fixed to the second wall 314.

[0035] The valve plate portion 32 includes a first mounting portion 321, and a first tongue portion 322 is connected to the first mounting portion 321. (See reference...) Figure 3 and Figure 4 The first assembly part 321 has an annular structure, and the first tongue 322 is located in the annular cavity of the first assembly part 321. One end of the first tongue 322 is connected to the first assembly part 321, and the other end is suspended in the annular cavity of the first assembly part 321.

[0036] The annular cavity of the first assembly portion 321 allows most of the periphery of the first tongue portion 322 to separate from the first assembly portion 321, while a small portion of the periphery of the first tongue portion 322 remains connected to the first assembly portion 321. The first tongue portion 322 is smaller in size than the first assembly portion 321. The smaller portion of the first tongue portion 322 facilitates elastic deformation, while the larger portion of the first assembly portion 321 serves as a base to ensure the strength of the valve plate portion 32.

[0037] Optionally, the valve plate portion 32 is a single piece. The valve plate portion 32 is made of a material that can undergo elastic deformation, has a certain strength, and good resilience. For example, the valve plate portion 32 is made of metal but has a small thickness. In some other embodiments, only the first tongue portion 322 may be made of a material that can undergo elastic deformation, has a certain strength, and good resilience to facilitate sealing or opening the connecting hole 302.

[0038] Optionally, the first tongue 322 and the first assembly part 321 can also be molded separately, assembled and fixed together.

[0039] Optionally, the valve plate section 32 has a plate-like structure and can be manufactured using stamping or cutting processes.

[0040] The limiting part 33 includes a second assembly part 331, and a second tongue part 332 is connected to the second assembly part 331. (See reference...) Figure 3 and Figure 4 The second assembly part 331 is an annular component, the second tongue part 332 is located in the annular cavity of the second assembly part 331, one end of the first tongue part 322 is connected to the second assembly part 331, and the other end is suspended in the annular cavity of the second assembly part 331.

[0041] The annular cavity of the second assembly part 331 allows most of the circumference of the second tongue 332 to separate from the second assembly part 331, while a small portion of the circumference of the second tongue 332 remains connected to the second assembly part 331. This arrangement reduces weight while ensuring the strength of the limiting part 33.

[0042] Reference Figures 3 to 5 The second tongue 332 includes a clearance surface 334, and the first tongue 322 is aligned with the clearance surface 334. The clearance surface 334 is inclined relative to the side of the partition 313 facing the first tongue 322. The clearance surface 334 is inclined starting from the connection point between the second tongue 332 and the second assembly part 331, providing sufficient space for the movement of the first tongue 322 and making it easier for the first tongue 322 to undergo elastic deformation. In the second state, the first tongue 322 is located in the gap between the clearance surface 334 and the partition 313, or the first tongue 322 is in contact with the clearance surface 334.

[0043] Optionally, the limiting part 33 is a single piece. The valve plate part 32 is made of a material with a certain strength. For example, the valve plate part 32 is made of metal, but its thickness is relatively large. Optionally, the second tongue part 332 and the second assembly part 331 can also be molded separately, assembled and fixed together.

[0044] Optionally, the limiting part 33 is a block structure and can be manufactured using processes such as stamping, cutting, and die casting.

[0045] At least part of the first assembly portion 321 is located between the partition portion 313 and the second assembly portion 331. Optionally, the shapes of the first assembly portion 321 and the second assembly portion 331 are matched. The second assembly portion 331 can be effectively clamped by the second assembly portion 331 to ensure the reliability of the valve plate portion 32 installation, thereby ensuring the reliability of the first tongue portion 322 blocking the communication hole 302.

[0046] The unidirectional component 3 includes a connecting part 34, a separating part 313 having a first through hole 316, a first assembly part 321 having a second through hole 323, a second assembly part 331 having a third through hole 333, a portion of the connecting part 34 being located in the first through hole 316, another portion of the connecting part 34 being located in the second through hole 323, and another portion of the connecting part 34 being located in the third through hole 333. The connecting part 34 is connected to the hole wall corresponding to the first through hole 316, the hole wall corresponding to the second through hole 323, and the hole wall corresponding to the third through hole 333.

[0047] Optionally, the hole wall corresponding to the first through hole 316, the hole wall corresponding to the second through hole 323, and the hole wall corresponding to the third through hole 333 are all provided with internal threads, and the outer side of the connecting part 34 is provided with external threads. The partition part 313, the valve plate part 32, and the limiting part 33 are fixed by threads.

[0048] Optionally, the connecting part 34, the hole wall corresponding to the first through hole 316, the hole wall corresponding to the second through hole 323, and the hole wall corresponding to the third through hole 333 can be fixed by means of adhesive or welding.

[0049] In some other possible embodiments, the first assembly part 321 and the second assembly part 331 may not be a ring structure, but may be designed in any other form. The second assembly part 331 is clamped by the second assembly part 331 and the partition part 313 to ensure the reliability of the valve plate part 32 installation, thereby ensuring the reliability of the first tongue part 322 blocking the communication hole 302. This application does not limit this.

[0050] In some possible embodiments, refer to Figures 1 to 5 The one-way component 3 includes a detection unit 35, which is assembled with the main body 312. A portion of the detection unit 35 is located in the first cavity 301. The detection unit 35 located in the first cavity 301 is aligned with the connecting hole 302, thereby accurately detecting fluid near the connecting hole 302. Optionally, the detection unit 35 is assembled with the cover 311. The connecting hole 302 is located in the second wall 314, extending through both sides of the second wall 314 along the length of the main body 312. Along the length of the main body 312, the detection unit 35 is located beside the connecting hole 302. The housing 31 not only serves as a component for realizing the one-way valve function but also as a mounting base for the detection unit 35, facilitating the proximity or separation of components, optimizing the layout design of parts, and promoting miniaturization.

[0051] According to a specific embodiment of the compression integration module of this application, such as Figures 6 to 9As shown, the compression integration module includes a compression component 4 and a unidirectional component 3 of any of the above embodiments. The compression component 4 includes a compressor core component 2 and a housing component 1. The housing component 1 has a mounting channel 103, a first channel 141, and a second channel 142. The first channel 141 and the second channel 142 are isolated from each other within the housing component 1. The compressor core component 2 is located in the mounting channel 103. The first channel 141 has two openings located on the shell wall of the housing component 1, and the second channel 142 also has two openings located on the shell wall of the housing component 1. The compressor core component 2 includes a compression section 22 with a compression chamber 201. The first channel 141 communicates with the compression chamber 201. The housing component 1 is assembled with the unidirectional component 3. The main body 312, on the side away from the cover 311, is sealed to the housing component 1. A first opening 304 communicates with the second channel 142, and a second opening 305 communicates with the first channel 141.

[0052] The compression integrated module of this application is assembled with housing assembly 1 and unidirectional assembly 3. The main body 312 is sealed to housing assembly 1 on the side away from cover 311. The first port 304 and the second port 305 of unidirectional assembly 3 are both located on the same side of main body 312. The first port 304 is connected to the second channel 142 and the second port 305 is connected to the first channel 141. This facilitates the integration of housing assembly 1 and unidirectional assembly 3 together and is conducive to miniaturization.

[0053] like Figure 8 As shown, the housing assembly 1 includes a first end cap 11, a second end cap 12, and a housing 13. The first end cap 11 and the second end cap 12 are respectively sealed to the housing 13. The housing 13 has the aforementioned mounting channel 103, which extends along the length of the housing 13. The first end cap 11 blocks one end of the mounting channel 103, and the second end cap 12 blocks the other end of the mounting channel 103.

[0054] The compressor core assembly 2 also includes a core section 21, and both the compression section 22 and the core section 21 are located between the first end cover 11 and the second end cover 12. The compression section 22, the core section 21, the first end cover 11 and the second end cover 12 are arranged along the length of the outer casing 13, with the compression section 22 closer to the first end cover 11 relative to the core section 21, and the core section 21 closer to the second end cover 12 relative to the compression section 22.

[0055] The core section 21 is driven to a portion of the compression section 22, and the core section 21 can drive the compression section 22 connected to the core section 21 to move. The core section 21 is driven to the moving parts of the compression section 22, and the core section 21 drives the moving parts of the compression section 22 to move relative to the stationary parts, thereby realizing the function of compressing fluid. The core section 21 of this application includes components such as a stator, rotor, and transmission mechanism. The function of compressing gaseous fluid can be realized through the compression section 22 and the core section 21. The structural design of the core section 21 and the working principle of realizing gaseous fluid compression are well known to those skilled in the art, and will not be described in detail here.

[0056] The compression assembly 4 has an exhaust chamber 101 located between the first end cap 11 and the compression section 22. The compression section 22 has an exhaust channel 202, and a check valve assembly 204 is provided at a position corresponding to the exhaust channel 202. When the check valve assembly 204 is in the open state, the exhaust channel 202 connects the outlet of the compression chamber 201 and the exhaust chamber 101; when the check valve is in the closed state, the check valve assembly 204 blocks one side opening of the exhaust channel 202, and the outlet of the compression chamber 201 and the exhaust chamber 101 are not connected.

[0057] The compression assembly 4 has an intake chamber 102 located between the second end cap 12 and the compression section 22. The intake chamber 102 is connected to the inlet of the compression chamber 201, and at least a portion of the core section 21 is located in the intake chamber 102. When fluid flows through the intake chamber 102, cooling of the core section 21 can be achieved.

[0058] The first channel 141 is connected to the middle section of the compression chamber 201. It's important to understand that, due to the working principle of the compression unit 22, the size and position of the compression chamber 201 change during operation. The middle section of the compression chamber 201 refers to a point between the inlet and outlet of the compression chamber 201, following the refrigerant flow direction. For example, if a scroll compressor is used, the middle section of the compression chamber 201 refers to a crescent-shaped cavity between the inlet and outlet of the compression chamber 201.

[0059] The compression section 22 has at least one air supply channel 203 extending inside the compression section 22. One end of each air supply channel 203 communicates with the first channel 141, and the other end of each air supply channel 203 communicates with any point in the middle region of the compression chamber 201. The air supply channel 203 communicates with the middle region of the compression chamber 201, where the fluid pressure is greater than the fluid pressure at the inlet of the compression chamber 201 but less than the fluid pressure at the outlet of the compression chamber 201, thereby achieving the effect of air supply and enthalpy increase.

[0060] Optionally, the compression unit 22 can adopt a reciprocating, screw, rotary, vortex, or centrifugal compression structure, as long as it can be used to increase low-pressure gas to high-pressure gas; this application is not limited to any particular type. For ease of description and explanation of the related relationships, this embodiment uses a vortex compression structure for the compression unit 22 as an example. When the compression unit 22 adopts other compression structures, the structure of the compression unit 22 itself and other components that cooperate with it are adapted accordingly, and the functions achieved are generally the same.

[0061] Reference Figure 8 and Figure 9 The compression section 22 includes a stationary scroll 221 and a moving scroll 222. The moving scroll 222 meshes with the stationary scroll 221 and can move relative to the stationary scroll 221. The compression chamber 201 is located between the stationary scroll 221 and the moving scroll 222, and the first channel 141 communicates with the middle section of the compression chamber 201. The stationary scroll 221 and the core section 21 are mounted on the outer casing 13, and the core section 21 is drivenly connected to the moving scroll 222. The exhaust chamber 101 is located between the first end cover 11 and the stationary scroll 221. The exhaust channel 202 extends along the length of the outer casing 13 through both sides of the stationary scroll 221 in the thickness direction. The intake chamber 102 is located between the moving scroll 222 and the second end cover 12. Optionally, the exhaust channel 202 is a cylindrical channel, and the central axis of the exhaust channel 202 coincides with the center line of the stationary scroll 221.

[0062] Reference Figure 9 The stationary volute 221 has at least one air supply channel 203 extending inside the stationary volute 221. One end of each air supply channel 203 communicates with the first channel 141, and the other end of each air supply channel 203 communicates with any point in the middle section region of the compression chamber 201. Optionally, the extension length of the air supply channel 203 is less than the diameter of the stationary volute 221. Optionally, all air supply channels 203 are straight holes, which are easier to manufacture than oblique holes.

[0063] In this embodiment, as Figures 6 to 9 As shown, the housing assembly 1 includes an outer shell 13 and a flow channel portion 14, which are separately formed and then assembled and fixed together. The outer shell 13 is located on one side of the flow channel portion 14 in the thickness direction, and the one-way assembly 3 is located on the other side of the flow channel portion 14 in the thickness direction. The length direction of the flow channel portion 14 coincides with or is parallel to the length direction of the outer shell 13, and the thickness direction of the flow channel portion 14 coincides with or is parallel to the length direction of the main body portion 312 of the one-way assembly 3.

[0064] The flow channel portion 14 includes a first side surface 145 and a second side surface 146 located on opposite sides in its thickness direction. The outer casing 13 includes a third side surface 134 facing the flow channel portion 14. The first side surface 145 and the third side surface 134 are fitted together and sealed together. The side of the main body portion 312 away from the cover portion 311 is fitted together and sealed together with the second side surface 146. Optionally, both the first side surface 145 and the third side surface 134 are planar, resulting in more stable surface-to-surface contact and higher reliability.

[0065] The compression integrated module includes a first plug 5. One end of the first plug 5 is inserted into the flow channel 14, and the other end is inserted into the compression section 22. The outer wall of the first plug 5 is sealed to both the flow channel 14 and the stationary scroll 221 of the compression section 22. The first plug 5 has a hollow internal structure and a first connecting cavity 50, which connects to the first channel 141 and the gas injection channel 203. The outer shell 13 has a first mounting hole 131 that penetrates a portion of the shell wall of the outer shell 13, and a portion of the first plug 5 is located within the first mounting hole 131. This configuration reduces the possibility of refrigerant leakage even if there is a gap between the outer shell 13 and the flow channel 14, and ensures the reliability of the connection between the first channel 141 and the gas injection channel 203.

[0066] The compression integration module includes a second plug 6. One end of the second plug 6 is inserted into the flow channel 14, and the other end is inserted into the outer casing 13. The outer wall of the second plug 6 is sealed to both the flow channel 14 and the outer casing 13. The second plug 6 has a hollow internal structure and a second connecting cavity 60, which connects the exhaust cavity 101 and the third channel 143 of the flow channel 14. The outer casing 13 has a second mounting hole 132, which penetrates another part of the outer casing 13. A portion of the second plug 6 is located within the second mounting hole 132. This configuration reduces the possibility of refrigerant leakage even if there is a gap between the outer casing 13 and the flow channel 14, ensuring reliable communication between the third channel 143 and the exhaust cavity 101.

[0067] The compression integration module includes a third plug 7. One end of the third plug 7 is inserted into the flow channel 14, and the other end is inserted into the outer casing 13. The outer wall of the third plug 7 is sealed to both the flow channel 14 and the outer casing 13. The third plug 7 has a hollow internal structure and a third connecting cavity 70, which connects the suction cavity 102 and the fourth channel 144 of the flow channel 14. The outer casing 13 has a third mounting hole 133, which penetrates another part of the outer casing 13. A portion of the third plug 7 is located within the third mounting hole 133. This configuration reduces the possibility of refrigerant leakage and ensures reliable communication between the fourth channel 144 and the suction cavity 102, even if there is a gap between the outer casing 13 and the flow channel 14.

[0068] The first channel 141, the second channel 142, the third channel 143 and the fourth channel 144 are provided in the flow channel section 14. Each channel has two openings located in the flow channel section 14. As required, the openings of the channels are distributed on the first side 145 and the second side 146 of the flow channel section 14.

[0069] In this embodiment, one side opening of the first channel 141 is located on the first side surface 145, and the other side opening is located on the second side surface 146. The first channel 141, which occupies relatively little space, connects the second cavity 303 of the unidirectional component 3 and the compression cavity 201 of the compression section 22, which is beneficial for miniaturization. Both sides of the second channel 142 are located on the second side surface 146, and the opening of the first channel 141 on the second side surface 146 is close to the opening on one side of the second channel 142, facilitating communication between the first channel 141 and the second cavity 303, and between the second channel 142 and the first cavity 301, which is also beneficial for miniaturization.

[0070] The openings on one side of the first channel 141, the third channel 143 and the fourth channel 144 are all located on the first side 145, and the openings on one side of the first assembly hole 131, the second assembly hole 132 and the third assembly hole 133 are all located on the third side 134, which facilitates the alignment and arrangement of the plug and the opening of the flow channel 14.

[0071] It is important to understand that the first channel 141, the second channel 142, the third channel 143, and the fourth channel 144 are isolated from each other within the flow channel section 14. Two channels can be connected through the inner cavity of the outer casing 13, the inner cavity of the one-way component 3, or the inner cavity of an external component. The first channel 141, the second channel 142, the third channel 143, and the fourth channel 144 connect with the inner cavity of the external component, functioning as pipelines and enabling communication between the inner cavities of external components. This allows the external components to be close to each other, which is beneficial for miniaturization. External components refer to components other than the flow channel section 14, such as the aforementioned one-way component 3 and outer casing 13. They can also be thermal management components such as heat exchangers, liquid receivers, gas-liquid separators, and expansion valves. The external components are assembled and fixed together with the flow channel section 14 to form an integrated device.

[0072] In certain operating conditions, the relevant thermal management system requires either diverting a portion of the refrigerant from the refrigerant circulation loop to the compression chamber 201, or taking a portion of the refrigerant from the compression chamber 201 and delivering it to the refrigerant circulation loop. To meet this requirement, an auxiliary assembly is added between the compressor end cover and the compression section 22. This auxiliary assembly includes multiple components such as an auxiliary cover plate, an auxiliary chamber, and a one-way valve assembly. Furthermore, it requires numerous external structures to match these new components, making the compressor structure more complex and increasing its axial dimension.

[0073] In this embodiment, the one-way component 3 can realize the function of a one-way valve. The compression part 22 is located in the mounting hole 103 of the outer shell 13. The one-way component 3 is located on the side of the shell wall of the shell component 1, which can reduce the axial dimension of the compression integrated module. Moreover, since the one-way component 3 has a compact structure and small size, the overall size of the compression integrated module is also small.

[0074] In some embodiments, refer to Figure 7 The compression integration module includes several brackets 8, which are connected to the housing assembly 1 to enable the installation of the compression integration module with other components, such as mounting and fixing it to the vehicle frame. Optionally, the brackets 8 and the housing 11 are integral; or the brackets 8 and the flow channel 14 are integral; or the brackets 8 are independently formed and then assembled and fixed together with at least one of the housing 11 or the flow channel 14.

[0075] In some other possible embodiments, the unidirectional component 3 can also be installed at the first end cover 11. Since the unidirectional component 3 has a relatively small structure, it can also reduce the size of the compression integrated module.

[0076] In some other possible embodiments, the housing 13 and the flow channel 14 may be an integral part, the structure of the housing 13 and the flow channel 14 may be adapted, and the compression integrated module may not be provided with the first plug 5, the second plug 6 and the third plug 7.

[0077] In some other possible embodiments, the housing assembly 1 includes only the outer shell 13 and excludes the flow channel 14. The outer shell 13, the first end cover 11, the second end cover 12, the compression section 22, the core section 21, and other necessary components together realize the function of the compressor. Together with the one-way assembly 3 and the air inlet channel 203, the compressor realizes the function of air inlet and enthalpy increase. The one-way assembly 3 is installed on the outer shell 13, and one side of the main body 312 in the length direction is sealed to the outer shell 13.

[0078] In this application, the assembly and fixing can be done by one or a combination of fasteners and other external components, such as bonding, snapping, welding, riveting, etc. The welding method includes one or a combination of brazing, resistance welding, friction stir welding, argon arc welding, etc.

[0079] In this application, the sealing connection can be achieved using O-rings. It can also be achieved through welding, including one or a combination of brazing, resistance welding, friction stir welding, and argon arc welding. Of course, other methods such as bonding or snap-fitting can also be used.

[0080] In this application, the integral part can be processed by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. to form a base material, and then processed by machining; or the integral part can be directly processed by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc.

[0081] Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this application, and all technical solutions and improvements that do not depart from the spirit and scope of this application should be covered within this application.
