[0027] With the rapid development of new energy vehicles, electric scroll compressor technology is also constantly being updated. It boasts advantages such as high efficiency and low noise, durability and reliability, wide operating range, lightweight design, and low cost, leading to its increasingly widespread application in new energy vehicles. The heat dissipation effect of the compressor control components has a significant impact on its operation. As the operating range of the compressor continues to increase, the compressor control components experience excessively high current and power during operation, resulting in increased heat dissipation. However, the refrigerant cannot dissipate this heat in time. Under conditions of high evaporation and condensation, the heat dissipation effect to the environment is negligible. Secondly, after the refrigerant gas is drawn in, it does not immediately fill the bottom of the casing and flows rapidly to the scroll working chamber under pressure difference. This causes heat to accumulate at the bottom of the casing, resulting in insufficient heat exchange, increased operating temperature, and reduced efficiency. When the control components are working, the power components generate significant heat, causing the temperature to rise. Simultaneously, the resistance of components increases with temperature, leading to greater energy consumption by the control components. Furthermore, excessively high temperatures can reduce or even damage the voltage withstand capability of capacitors, thereby reducing the stability of the control components.

[0028] To solve the above-mentioned technical problems, this application provides a compressor, referring to... Figure 1 and Figure 2 As shown, the compressor includes a core assembly 10, a control assembly 20, and a housing 30. The housing 30 forms a first chamber 31, a second chamber 32, and a low-pressure air inlet 33. The core assembly 10 is located in the first chamber 31, and the control assembly 20 is located in the second chamber 32. The housing 30 also includes an isolation wall 34 and a heat sink assembly 35. The isolation wall 34 is located between the first chamber 31 and the second chamber 32, and the heat sink assembly 35 is located on the side of the isolation wall 34 facing the first chamber 31. The core assembly 10 is used to drive the scroll assembly to achieve gas compression, and the control assembly 20 is used to control the electrical signals of the core assembly 10. The low-pressure air inlet 33 is connected to the first chamber 31. The iron core assembly 10 is located in the first chamber 31, and the control assembly 20 is located in the second chamber 32. The housing 30 also includes an isolation wall 34 and a heat sink assembly 35. The isolation wall 34 is located between the first chamber 31 and the second chamber 32. The heat sink assembly 35 is located on the side of the isolation wall 34 facing the first chamber 31, and is located in the first chamber 31 near the low-pressure air inlet 33. The mixed oil and gas enter the first chamber 31 through the low-pressure air inlet 33. The heat generated by the control assembly 20 installed in the second chamber 32 can be transferred to the first chamber 31 through the isolation wall 34 and the heat sink assembly 35 located on the isolation wall 34. The mixed oil and gas carries away the heat from the isolation wall 34 and the heat sink assembly 35. Since the combination of heat sink assembly 35 and isolation wall 34 can increase the heat dissipation area compared to isolation wall 34 alone, and the heat sink assembly 35 is close to the low-pressure air inlet 33, the mixed oil and gas can carry away more heat, thereby increasing the heat dissipation efficiency of control component 20 and increasing the working stability of control component 20.

[0029] In some embodiments, the mixed oil and gas entering from the low-pressure inlet 33 includes low-temperature, low-pressure gas, cooling oil, and other refrigerants.

[0030] In some embodiments, refer to Figure 1 As shown, the housing 30 includes a first housing portion 301, a second housing portion 302, and a third housing portion 303, which are configured as an integral structure. Figure 2 As shown, the first housing portion 301 forms the first chamber 31, and the second housing portion 302 and the third housing portion 303 cooperate to form the second chamber 32. The third housing portion 303 is located radially outside the first housing portion 301 and the second housing portion 302, and the third housing portion 303 is provided with a wiring terminal 304 for connecting the IGBT element 22. The first housing portion 301, the second housing portion 302, and the third housing portion 303 are integrated into a single structure through an integral molding process. The radially outer position of the third housing portion 303 reduces the axial length of the housing 30, and its placement radially outside the first and second housing portions 303 allows for better compatibility with the compressor and other components.

[0031] In some embodiments, referring to Figure 2, the core assembly 10 includes a rotor 11 and a stator 13. The stator 13 is a stationary component, typically containing windings or permanent magnets, used to generate a magnetic field; the rotor 11 is the rotating part, converting electrical energy into mechanical energy through electromagnetic interaction. The stator 13 is the motor's "magnetic field generator," establishing a magnetic field through windings or permanent magnets, while the rotor 11 is the motor's "energy converter," rotating under force in the magnetic field to achieve electromechanical energy conversion. The two work closely together through electromagnetic interaction.

[0032] In some embodiments, referring to Figure 2, the control component 20 includes structures such as IGBT elements 22 and copper busbar components. Through voltage-controlled conduction and conductivity modulation effects, it achieves a balance between low loss and high reliability in high-voltage and high-current scenarios.

[0033] In some embodiments, the control component 20 reduces the losses of the core assembly 10 and improves the reliability of its operation through voltage control and conductivity modulation effects. The stator 13 and rotor 11 of the core assembly 10 cooperate to achieve energy conversion, driving the vortex compression component in the vortex working chamber to compress the gas.

[0034] In some embodiments, refer to Figure 2As shown, the first chamber 31 can be a cylindrical chamber, or it can be set to other shapes according to the actual situation. In the first chamber 31, the core assembly 10 and the isolation wall 34 can be spaced apart. The gap between the core assembly 10 and the isolation wall 34 can be used to temporarily store a portion of the mixed oil and gas, allowing the mixed oil and gas to fully contact the isolation wall 34 and the heat sink assembly 35 inside, thereby achieving better heat dissipation. The second chamber 32 can be set according to the shape of the control assembly 20 to accommodate the control assembly 20. Since the shape of the control assembly 20 is generally irregular, the second chamber 32 is also irregular in shape, and can be set according to the actual situation.

[0035] In some embodiments, refer to Figure 3 As shown, the heat sink assembly 35 includes a central fin group 351 and a peripheral fin group 352. In the radial direction of the first chamber 31, the peripheral fin group 352 is located outside the central fin group 351. The central fin group 351 includes a plurality of first fins 3511, which are spaced apart around the axial direction of the first chamber 31. The peripheral fin group 352 includes a plurality of second fins 3521, which are spaced apart around the axial direction of the first chamber 31. The heat sink assembly 35 is a sheet-like structure protruding into the first chamber 31. The heat sink assembly 35 and the isolation wall 34 can be configured as an integral structure, formed using processes such as integral casting. The central fin group 351 of the heat sink assembly 35 is located on the side closer to the central axis of the first chamber 31, and the peripheral fin group 352 of the heat sink assembly 35 is located on the side farther from the central axis of the first chamber 31, thus placing the peripheral fin group 352 outside the central fin group 351 in the radial direction of the first chamber 31. The first fins 3511 of the central fin assembly 351 have an arc-shaped structure and are distributed in multiple rings from near the center axis of the first chamber 31 away from the center axis. Each ring includes multiple spaced-apart arc-shaped first fins 3511. The second fins 3521 of the peripheral fin assembly 352 have a fin-like structure and extend spirally from near the sidewall of the first chamber 31 away from the sidewall. The peripheral fin assembly 352 has at least one ring, with multiple second fins 3521 spaced apart in each ring, giving the heat sink assembly 35 a larger heat dissipation area. Thus, by increasing the heat dissipation area of ​​the central fin assembly 351 and the peripheral fin assembly 352, a better heat dissipation effect is achieved.

[0036] In some embodiments, refer to Figure 3As shown, multiple first fins 3511 are staggered in the radial direction of the first chamber 31. The radial direction is the direction from the central axis of the first chamber 31 to the sidewall of the first chamber 31. The central fin group 351 includes multiple rings of first fins 3511, and each ring includes multiple spaced-apart first fins 3511. Adjacent first fins 3511 on the circumference of the central axis of the first chamber 31 are spaced apart. When the first fins 3511 are staggered in the direction from the central axis of the first chamber 31 to the sidewall of the first chamber 31, the spacing between the first fins 3511 also alternates. Mixed oil and gas can enter the inner ring of first fins 3511 from the spacing of the outer ring, thus ensuring more thorough contact between the first fins 3511 and the mixed oil and gas, thereby improving heat dissipation. This also effectively lubricates moving parts and enhances the turbulence of the oil and gas, actively generating turbulence and improving heat exchange.

[0037] In some embodiments, refer to Figure 3 As shown, the height of the second fin 3521 gradually decreases from near the sidewall of the first chamber 31 to away from the sidewall of the first chamber 31, and the height of the second fin 3521 is greater than the height of the first fin 3511. The heights of the first fin 3511 and the second fin 3521 are their dimensions perpendicular to the partition wall 34. Multiple second fins 3521 are spaced apart, with at least one spaced second fin 3521 located at the inlet end of the low-pressure air inlet 33, thereby guiding the mixed oil and gas from the low-pressure air inlet 33 into the central fin assembly 351 through the peripheral fin assembly 352. This results in better heat dissipation through the guiding effect of the peripheral fin assembly 352. Furthermore, the shear force generated by the gas impacting the second fins 3521 breaks the cooling oil into smaller particles, forming a more uniform oil-gas mixture.

[0038] In some embodiments, refer to Figure 4 As shown, the isolation wall 34 forms a mounting base 341; the compressor includes a bearing 40; combined with Figure 2 As shown, the core assembly 10 includes a rotor 11 and a shaft 12. The rotor 11 is mounted on the shaft 12, and one end of the shaft 12 is connected to a bearing 40, which is mounted on a mounting base 341. Figure 3As shown, the mounting base 341 is provided with a first oil-gas passage 3411, which connects to the low-pressure air inlet 33 through the first chamber 31. The mounting base 341 has a bearing hole and is an annular mounting base. The bearing hole is an annular bearing hole with a hole wall in the radial direction. The first oil-gas passage 3411 passes through the hole wall and communicates with the bearing hole. The rotating shaft 12 is mounted in the bearing hole through the bearing 40. The first oil-gas passage 3411 can allow the mixed oil and gas to flow into the bearing hole, thereby cooling and dissipating heat from the bearing 40 and reducing the risk of high-temperature failure of the bearing 40. Specifically, the first oil-gas passage 3411 is directly facing the air intake. When the mixed oil and gas is drawn in, it carries the coolant to the bearing hole in the mounting base 341, achieving sufficient lubrication of the bearing.

[0039] In some embodiments, the first oil-gas passage 3411 is arranged opposite to the low-pressure air inlet 33 in the radial direction of the mounting base 341. The mounting base 341 is a circular mounting base, and the radial direction of the mounting base 341 is the direction in which its central axis points to the side wall of the first chamber 31. Based on the communication between the first oil-gas passage 3411 and the low-pressure air inlet 33, further arranging the first oil-gas passage 3411 opposite to the low-pressure air inlet 33 can allow more mixed oil and gas to enter the mounting base 341, thereby increasing the cooling and lubrication effects of the bearing 40.

[0040] In some embodiments, refer to Figure 4As shown, the low-pressure air inlet 33 includes a first hole 331 and a second hole 332 that are connected. The first hole 331 extends in a direction perpendicular to the side wall of the first chamber 31, and the second hole 332 extends in a direction inclined to the side wall of the first chamber 31. In the axial direction of the first chamber 31, one end of the second hole 332 facing the first hole 331 is away from the heat sink assembly 35, and the other end of the second hole 332 facing the first chamber 31 is close to the heat sink assembly 35. On one hand, the first hole 331 is used to connect to an external air intake pipe of the compressor, and the second hole 332 can guide the mixed oil and gas in the inclined direction. The inclined second hole 332 can guide the mixed oil and gas to the vicinity of the heat sink assembly 35, reducing the flow distance of the gas from the first chamber 31 to the heat sink assembly 35. On the other hand, since the gas at the low-pressure inlet 33 is not only a mixture of oil and gas but also a low-pressure gas, and the gas in the compression working chamber is a low-temperature, high-pressure gas, when the mixed oil and gas enters the first chamber 31, it will actively move towards the compression working chamber with the low-temperature, high-pressure gas, increasing the flow velocity of the mixed oil and gas into the compression working chamber. Furthermore, the rotation of the core assembly 10 generates eddies, which also increase the flow velocity of the mixed oil and gas into the compression working chamber. Therefore, the inclined second hole 332 can reduce the flow distance of the gas from the first chamber 31 to the heat sink assembly 35, and can at least overcome the effect of rapid loss of the mixed oil and gas, thereby improving the heat dissipation efficiency of the heat sink assembly 35.

[0041] In some embodiments, combined with Figure 2 As shown, the core assembly 10 includes a rotor 11 and a stator 13. The stator 13 is connected to the side wall of the first chamber 31, and the rotor 11 is located radially inside the stator 13. The stator 13 and the rotor 11 are spaced apart. (Refer to...) Figure 4 As shown, the gap between the stator 13 and the rotor 11 connects with the first chamber 31 to form a second oil-gas passage 14. The stator 13 is the "magnetic field generator" of the motor, establishing a magnetic field through windings or permanent magnets. The rotor 11 is the "energy converter" of the motor, rotating under the force of the magnetic field to realize electromechanical energy conversion. A gap is necessary between the rotor 11 and the stator 13 to achieve relative rotation. When the mixed oil and gas from the low-pressure inlet 33 enters the first chamber 31, the rotation of the rotor 11 and the stator 13 allows the gas to flow through the gap between them to the compression working chamber. The rotor 11 then drives the moving scroll assembly, and the interaction between the moving and stationary scroll assemblies compresses the gas to form high-pressure gas.

[0042] In some embodiments, refer to Figure 3 As shown, the isolation wall 34 forms a mounting hole 342, which connects the first chamber 31 and the second chamber 32; the control assembly 20 includes a connection terminal 21, which is combined with... Figure 2As shown, the connecting terminal 21 passes through the mounting hole 342 and connects to the stator 13; the compressor also includes a seal 50, which is disposed between the mounting hole 342 and the connecting terminal 21. Figure 2 As shown, one side of the connection terminal 21 is used to connect to the IGBT element 22 of the control component 20, and the other side of the connection terminal 21 is connected to the stator 13. The electrical signal is converted and modulated by the IGBT element 22 and then transmitted to the stator 13. The magnetic field generated by the stator 13 drives the rotor 11 to rotate. The sealing element 50 between the mounting hole 342 and the connection terminal 21 can prevent the mixed oil and gas from entering the connection terminal 21, thus protecting the connection terminal 21. At the same time, the sealing element 50 can also transfer heat from the connection terminal 21, thus dissipating heat from the connection terminal 21.

[0043] In some embodiments, refer to Figure 2 As shown, the control assembly 20 also includes an IGBT element 22, a heat-conducting component 23, and a thermally conductive adhesive 24. The heat-conducting component 23 is disposed between the IGBT element 22 and the isolation wall 34. A thermally conductive sheet 231 is formed on the side of the heat-conducting component 23 facing the isolation wall 34, and the thermally conductive sheet 231 abuts against the isolation wall 34. The thermally conductive adhesive 24 is disposed between the thermally conductive sheet 231 and the isolation wall 34. The IGBT element 22 generates a large amount of heat during operation and is the component that generates the most heat in the control assembly 20. The heat-conducting component 23 connecting the IGBT element 22 abuts against the isolation wall 34, and the thermally conductive adhesive 24 is filled between the heat-conducting component 23 and the isolation wall 34 to transfer heat to the isolation wall 34. The heat is then transferred to the first chamber 31 through the isolation wall 34 and the heat sink assembly 35. The mixed oil and gas in the first chamber 31 carries away the heat and plays a role in heat dissipation. The heatsink 231 is a metal heatsink. After being assembled with the IGBT element 22, it is installed in the second chamber 32, with the heatsink 231 pressed against the isolation wall 34. This design results in insufficient contact between the heatsink 231 and the isolation junction, and a limited contact area between the heatsink 231 and the isolation wall 34, leading to unsatisfactory heat dissipation. Therefore, thermally conductive adhesive 24 is filled between the heatsinks 231. Because thermally conductive adhesive 24 has better thermal conductivity and is a flexible material, it allows for more sufficient contact with the isolation wall 34, thus improving heat dissipation.

[0044] In this application, the mixed oil and gas enters the first chamber 31 through the low-pressure inlet 33. The heat generated by the control component 20 installed in the second chamber 32 can be transferred to the first chamber 31 through the isolation wall 34 and the heat sink assembly 35 disposed on the isolation wall 34. The mixed oil and gas carries away the heat from the isolation wall 34 and the heat sink assembly 35. Since the combination of the heat sink assembly 35 and the isolation wall 34 increases the heat dissipation area compared to the isolation wall 34 alone, the mixed oil and gas can carry away more heat, thereby increasing the heat dissipation efficiency of the control component 20 and improving the operational stability of the control component 20. The heat sink assembly 35 includes a central fin group 351 and a peripheral fin group 352. By increasing the heat dissipation area of ​​the central fin group 351 and the peripheral fin group 352, and through the guiding effect of the peripheral fin group 352, a better heat dissipation effect is achieved.

[0045] This application also provides a refrigeration device, including the aforementioned compressor. The refrigeration device can be applied to devices such as vehicles, air conditioners, and refrigerators. The compressor designed in this way can also provide better heat dissipation for devices such as vehicles, air conditioners, and refrigerators.

[0046] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
