Description

Technical Field

[0001] This application belongs to the technical field of air compressors, specifically relating to a scroll air compressor. Background Technology

[0002] A scroll air compressor is an oil-free scroll air compressor that features low noise, low vibration, and high efficiency. It is mainly used in fields such as oxygen generators where the quality of compressed air is critical.

[0003] Because scroll air compressors are oil-free, the heat they generate during operation cannot be carried away by lubricating oil like in oil-lubricated air compressors. Therefore, it is necessary to equip scroll air compressors with additional fans for heat dissipation, in order to remove the heat generated by the relative movement of moving parts and the work done by the compressed gas, so as to ensure that the scroll air compressor can work normally for a long time and extend the service life of the scroll compressor.

[0004] To improve the heat dissipation efficiency of scroll air compressors, two methods are typically used. One is to increase the fan speed. However, increasing the fan speed will increase noise, thus affecting the user experience. The other is to increase the fan size while maintaining the original speed. However, the fan size is limited by the size of the scroll air compressor. Simply increasing the fan size will cause some of the cold air generated by the fan to be blown to the outside of the scroll air compressor, resulting in low utilization of the cold air and poor heat dissipation effect. Utility Model Content

[0005] This application provides a scroll air compressor that improves heat dissipation while reducing noise.

[0006] The technical solution adopted in this application is as follows:

[0007] A scroll air compressor, comprising:

[0008] A vortex assembly, comprising a support and a stationary vortex disk and a moving vortex disk that cooperate with each other, wherein the upper end surface of the stationary vortex disk is provided with multiple heat dissipation fins.

[0009] A flow guiding assembly includes a cover plate and a guide plate. The cover plate is disposed on the side of the heat dissipation fins away from the static vortex disk so that the cover plate and the heat dissipation fins together form a heat dissipation channel. The guide plate has a first end connected to the cover plate and a second end opposite to the first end. The guide plate is inclined from the first end to the second end in a direction away from the heat dissipation fins.

[0010] A cooling fan is provided near the second end to blow cooling airflow into the cooling channel through the air inlet.

[0011] By adopting the above technical solution, when the cooling fan is working, the cooling airflow it generates is blown into the cooling channel through the air inlet of the cooling channel to dissipate heat from the scroll air compressor. Since the guide plate is inclined from the first end to the second end away from the cooling fins, and the cooling fan is set close to the second end, the cooling airflow generated by the cooling fan can flow entirely into the cooling channel under the action of the guide plate, thereby reducing the loss of cooling airflow, improving the utilization rate of cooling airflow, and greatly improving the cooling efficiency of the scroll air compressor. Furthermore, the size of the cooling fan is no longer limited by the size of the scroll air compressor, allowing for the configuration of a larger cooling fan for the scroll air compressor. This improves the cooling efficiency of the scroll air compressor while ensuring that the cooling fan speed remains the same, and avoids the increase in noise caused by increasing the speed of the cooling fan.

[0012] Meanwhile, the flow guiding component in this application mainly serves to guide the heat dissipation airflow, thereby reducing the thickness of the flow guiding component, reducing the weight of the flow guiding component, and thus reducing the weight of the scroll air compressor and the production cost of the scroll air compressor.

[0013] Optionally, the guide plate includes a guide section and a connecting section. The guide section is connected to the cover plate and is inclined. The plane of the connecting section is parallel to the plane of the cover plate. The cooling fan is connected to the connecting section.

[0014] By adopting the above technical solution, when the cooling fan is working, the cooling airflow it generates first passes through the connecting section, and then, under the guidance of the guide section, enters the cooling channel through the air inlet of the cooling channel to dissipate heat from the scroll air compressor. Since the connecting section is set parallel to the cover plate, and the cooling fan is connected to the connecting section, on the one hand, it can increase the stability of the cooling fan and reduce the collision that may be caused by the vibration of the cooling fan and the scroll air compressor during operation, thereby reducing the noise of the scroll air compressor. On the other hand, it can reduce the difficulty of connecting the cooling fan and the connecting section, thereby improving the assembly efficiency of the cooling fan and reducing the assembly cost of the cooling fan. Furthermore, the setting of the connecting section makes the flow of cooling air smoother, avoiding the situation where the cooling airflow is not smooth due to the small distance between the guide section and the cooling fan, thereby further improving the cooling efficiency of the scroll air compressor. In addition, the connection of the cooling fan to the connecting section can also support the guide plate, thereby increasing the stability of the guide plate.

[0015] Optionally, the connecting section is provided with a connecting part for mounting the cooling fan, and the connecting part is located on the side of the connecting section close to the cooling fins.

[0016] By adopting the above technical solution, since the connecting part is located on the side of the connecting section closer to the heat dissipation fins, and the connecting part is used for the installation of the cooling fan, the cooling fan is located on the side of the connecting section closer to the heat dissipation fins, so as to ensure the guiding effect of the guide plate on the cooling airflow, thereby further improving the utilization rate of the cooling airflow and further improving the cooling efficiency of the scroll air compressor; at the same time, the setting of the connecting part can also facilitate the connection of the cooling fan to the guide plate, thereby improving the assembly efficiency of the cooling fan.

[0017] Optionally, the airflow guiding assembly further includes a baffle plate connected to the guide plate, the baffle plate having a mounting position for mounting the cooling fan to guide the airflow generated by the cooling fan to the heat dissipation channel.

[0018] By adopting the above technical solution, when the cooling fan is working, the baffle plate can block the cooling airflow generated by the cooling fan, so that more cooling airflow can flow to the scroll air compressor, thereby further reducing the loss of cooling airflow, improving the utilization rate of cooling airflow, and further improving the cooling efficiency of the scroll air compressor.

[0019] Optionally, the baffle plate includes a flow-blocking section located on the side of the cooling fan and a blocking section located outside the flow-blocking section, wherein the blocking section and the flow-blocking section are arranged at an angle.

[0020] By adopting the above technical solution, since the flow obstruction section is located on the side of the cooling fan, it blocks the side of the cooling fan to prevent the cooling airflow from flowing away from the side of the cooling fan due to resistance. Since the blocking section is located outside the flow obstruction section, it can block and guide the cooling airflow that flows to the outside of the cooling fan due to resistance, so as to guide the cooling airflow to the scroll air compressor, thereby further improving the cooling efficiency of the scroll air compressor.

[0021] Optionally, the flow-blocking section is provided with mounting holes for connecting the flow-guiding assembly to the bracket.

[0022] By adopting the above technical solution, since the flow obstruction section is provided with mounting holes, and the mounting holes are used to connect the flow guiding component to the bracket, on the one hand, the stability of the flow guiding component is increased, and the noise caused by the relative movement between the flow obstruction section and the scroll air compressor is avoided. On the other hand, the assembly difficulty of the flow guiding component is reduced and the assembly efficiency of the flow guiding component is improved.

[0023] Optionally, a fixing plate is provided at the end of the baffle plate away from the guide plate, and the fixing plate is provided with a mounting hole for connecting the flow guiding component to the bracket.

[0024] By adopting the above technical solution, since the fixing plate is provided with mounting holes and is located at the end of the blocking plate away from the guide plate, the blocking plate can be connected to the bracket to increase the stability of the blocking plate. At the same time, the fixing plate can cooperate with the bracket in the vertical upward direction to further increase the stability of the blocking plate.

[0025] Optionally, the vortex assembly further includes an air supply connector and an air outlet connector. Multiple first heat dissipation channels and multiple second heat dissipation channels are formed between the multiple heat dissipation fins. The air supply connector and the air outlet connector are located between the first heat dissipation channels and the second heat dissipation channels. The first heat dissipation channels are located close to the cooling fan, and the extension direction of the first heat dissipation channels is parallel to the airflow direction of the cooling fan. The second heat dissipation channels extend away from the air outlet connector and are located away from the air supply connector.

[0026] By adopting the above technical solution, since both the air supply connector and the air outlet connector are located between the first heat dissipation channel and the second heat dissipation channel, the heat dissipation airflow flows through the first heat dissipation channel to the air supply connector and the air outlet connector to achieve heat dissipation of the air supply connector and the air outlet connector; at the same time, the second heat dissipation channel extends away from the air outlet connector and is set away from the air supply connector, so that the heat dissipation airflow blown towards the air outlet connector is discharged through the second heat dissipation channel, so as to avoid the situation where the heat dissipation airflow flowing towards the air outlet connector is heated by the air outlet connector and flows back to the air supply connector, thereby preventing the intake air temperature of the scroll air compressor from rising.

[0027] Optionally, the cover plate is provided with a plurality of connection holes for screws to pass through, so that the cover plate can be fixedly connected to the heat dissipation fins by screws.

[0028] By adopting the above technical solution, since the cover plate is provided with multiple connection holes for screws to pass through, the cover plate can be fixedly connected to the heat dissipation fins using screws, thereby increasing the stability of the airflow guiding component, reducing the assembly difficulty of the airflow guiding component, and improving the assembly efficiency of the airflow guiding component.

[0029] Optionally, the cover plate is provided with an air supply connector and a through hole through which the air supply connector passes.

[0030] By adopting the above technical solution, since the cover plate is provided with an air supply and outlet connector and a through hole through which the air supply connector passes, the air supply and outlet connector can pass through the cover plate, so as to facilitate the connection of external pipelines to the air supply and outlet connectors. At the same time, it can also allow some of the heat dissipation airflow to flow through the first heat dissipation channel to the air supply and outlet connectors and then be discharged through the through hole, thereby improving the heat dissipation effect on the air supply and outlet connectors, reducing the flow resistance of the heat dissipation airflow in the first heat dissipation channel, and further improving the heat dissipation efficiency of the scroll air compressor.

[0031] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0032] 1. The scroll air compressor of this application includes a scroll assembly, a flow guiding assembly, and a cooling fan. The scroll assembly includes a bracket and a stationary scroll and a moving scroll that cooperate with each other. The upper surface of the stationary scroll is provided with multiple heat dissipation fins. The flow guiding assembly includes a cover plate and a guide plate. The cover plate is located on the side of the heat dissipation fins away from the stationary scroll, so that the cover plate and the heat dissipation fins together form a heat dissipation channel. The guide plate has a first end connected to the cover plate and a second end opposite to the first end. The guide plate is inclined from the first end to the second end in a direction away from the heat dissipation fins. The cooling fan is located close to the second end to blow the cooling airflow into the heat dissipation channel through the air inlet of the heat dissipation channel. This allows the cooling airflow generated by the cooling fan to flow entirely into the heat dissipation channel under the action of the guide plate, thereby reducing the loss of cooling airflow, improving the utilization rate of cooling airflow, and greatly improving the heat dissipation efficiency of the scroll air compressor. At the same time, the size of the cooling fan is no longer limited by the size of the scroll air compressor, so that a larger cooling fan can be configured for the scroll air compressor, avoiding the increase in noise caused by increasing the speed of the cooling fan.

[0033] 2. The guide plate in this application includes a guide section and a connecting section. The guide section is connected to the cover plate and is inclined, while the connecting section is parallel to the cover plate. The cooling fan is connected to the connecting section. On the one hand, this increases the stability of the cooling fan and reduces the collision that may occur when the cooling fan vibrates with the scroll air compressor during operation, thereby reducing the noise of the scroll air compressor. On the other hand, it reduces the difficulty of connecting the cooling fan and the connecting section, thereby improving the assembly efficiency of the cooling fan and reducing the assembly cost of the cooling fan. Furthermore, the connecting section makes the flow of cooling air smoother, avoiding the situation where the cooling air flow is not smooth due to the small distance between the guide section and the cooling fan, thus further improving the cooling efficiency of the scroll air compressor. In addition, the connection of the cooling fan to the connecting section also allows the cooling fan to support the guide plate, thereby increasing the stability of the guide plate.

[0034] 3. The connecting section in this application is provided with a connecting part for installing a cooling fan. The connecting part is located on the side of the connecting section closer to the heat dissipation fins, thereby placing the cooling fan on the side of the connecting section closer to the heat dissipation fins. This ensures the guiding effect of the guide plate on the cooling airflow, further improving the utilization rate of the cooling airflow and thus further improving the cooling efficiency of the scroll air compressor. At the same time, the setting of the connecting part also facilitates the connection of the cooling fan to the guide plate, thereby improving the assembly efficiency of the cooling fan.

[0054] Reference Figures 1 to 11 A scroll air compressor is disclosed, comprising a scroll assembly 1, a flow guiding assembly 2, and a cooling fan 3. The scroll assembly 1 includes a support 11 and a stationary scroll 12 and a moving scroll 13 that cooperate with each other. The upper surface of the stationary scroll 12 is provided with a plurality of heat dissipation fins 121. The flow guiding assembly 2 includes a cover plate 21 and a guide plate 22. The cover plate 21 is located on the side of the heat dissipation fins 121 away from the stationary scroll 12, so that the cover plate 21 and the heat dissipation fins 121 together form a heat dissipation channel 122. The guide plate 22 has a first end connected to the cover plate 21 and a second end opposite to the first end. The guide plate 22 is inclined from the first end to the second end in a direction away from the heat dissipation fins 121. The cooling fan 3 is located near the second end to blow the cooling airflow into the heat dissipation channel 122 through the air inlet of the heat dissipation channel 122.

[0055] It should be noted that the cooling airflow mentioned above refers to the airflow generated by the cooling fan 3; the extension direction of the cooling fins 121 is towards or away from the cooling fan 3, thereby forming an air inlet on the side where the cooling channel 122 is located.

[0056] When the cooling fan 3 is working, the cooling airflow it generates is blown into the cooling channel 122 through the air inlet of the cooling channel 122 to dissipate heat from the scroll air compressor. Since the guide plate 22 is inclined from the first end to the second end away from the cooling fins 121, and the cooling fan 3 is set close to the second end, the cooling airflow generated by the cooling fan 3 can flow into the cooling channel 122 under the action of the guide plate 22, thereby reducing the loss of cooling airflow, improving the utilization rate of cooling airflow, and greatly improving the cooling efficiency of the scroll air compressor. In addition, the size of the cooling fan 3 is no longer limited by the size of the scroll air compressor, so that a larger cooling fan 3 can be configured for the scroll air compressor. This improves the cooling efficiency of the scroll air compressor while ensuring that the cooling fan 3 maintains the original speed, and avoids the situation where the noise increases due to the increase of the speed of the cooling fan 3.

[0057] This application does not specifically limit the structure of the guide plate 22; preferably, refer to... Figure 1 , Figure 4 , Figure 5 , Figure 9 and Figure 10 The guide plate 22 includes a guide section 221 and a connecting section 222. The guide section 221 is connected to the cover plate 21 and is inclined. The plane where the connecting section 222 is located is parallel to the plane where the cover plate 21 is located. The cooling fan 3 is connected to the connecting section 222.

[0058] It is understandable that the end of the guide section 221 away from the connecting section 222 forms the first end, and the end of the connecting section 222 away from the guide section 221 forms the second end. The guide section 221 is inclined in the direction away from the cover plate 21 and is set in the direction away from the heat dissipation fins 121.

[0059] In one embodiment, the upper part of the cooling fan 3 is connected to the connecting section 222, and the lower part of the cooling fan 3 is connected to the bracket 11.

[0060] When the cooling fan 3 is working, the cooling airflow it generates first passes through the connecting section 222, and then, under the guidance of the guide section 221, enters the cooling channel 122 through the air inlet of the cooling channel 122 to cool the scroll air compressor. Since the connecting section 222 is set parallel to the cover plate 21, the cooling fan 3 is connected to the connecting section 222. On the one hand, this can increase the stability of the cooling fan 3 and reduce the collision that may be caused by the vibration of the cooling fan 3 and the scroll air compressor during operation, so as to reduce the noise of the scroll air compressor. On the other hand, it can reduce the difficulty of connecting the cooling fan 3 and the connecting section 222, thereby improving the assembly efficiency of the cooling fan 3 and reducing the assembly cost of the cooling fan 3.

[0061] Furthermore, the connection section 222 makes the flow of cooling air smoother, so as to avoid the situation where the flow of cooling air is not smooth due to the small distance between the guide section 221 and the cooling fan 3, thereby further improving the cooling efficiency of the scroll air compressor. In addition, the cooling fan 3 connected to the connection section 222 can also support the guide plate 22, thereby increasing the stability of the guide plate 22.

[0062] This application does not specify the connection method between the cooling fan 3 and the connecting section 222. Preferably, refer to... Figure 1 , Figure 4 , Figure 5 , Figure 9 and Figure 10The connecting section 222 is provided with a connecting part 223 for mounting the cooling fan 3. The connecting part 223 is located on the side of the connecting section 222 close to the heat dissipation fins 121, thereby placing the cooling fan 3 on the side of the connecting section 222 close to the heat dissipation fins 121. This ensures the guiding effect of the guide plate 22 on the cooling airflow, further improving the utilization rate of the cooling airflow and thus further improving the cooling efficiency of the scroll air compressor. At the same time, the setting of the connecting part 223 also facilitates the connection of the cooling fan 3 to the guide plate 22, thereby improving the assembly efficiency of the cooling fan 3.

[0063] Preferably, the cooling fan 3 is connected to the connecting part 223 by screws, bolts or snap-fit ​​parts that can engage with the connecting part 223, so as to reduce the installation difficulty of the cooling fan 3 and improve the installation efficiency of the cooling fan 3.

[0064] This application does not specifically limit the structure of the connecting part 223; preferably, refer to... Figure 1 , Figure 4 , Figure 5 , Figure 9 and Figure 10 The connecting portion 223 is a sheet-like structure extending from the connecting segment 222 to reduce the weight of the flow guiding assembly 2 and also reduce the manufacturing difficulty of the flow guiding assembly 2. In other embodiments, the connecting portion 223 may also be a block-like structure provided on the connecting segment 222.

[0065] In other embodiments, the connecting section 222 may be thickened so that screws or clips for fixing the cooling fan 3 can pass through the connecting section 222.

[0066] In other embodiments, the guide plate 22 may only include the guide section 221, that is, the design of the connecting section 222 is omitted, and the entire guide plate 22 is inclined.

[0067] In a preferred embodiment, refer to Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10 The airflow guiding assembly 2 also includes a baffle plate 23 connected to the guide plate 22. The baffle plate 23 has a mounting position for mounting the cooling fan 3, so as to guide the airflow generated by the cooling fan 3 to the heat dissipation channel 122.

[0068] It should be noted that the aforementioned mounting position refers to the hollow structure provided in the baffle plate 23, so that the baffle plate 23 can avoid the fan blades of the cooling fan 3, thereby allowing the cooling airflow generated by the cooling fan 3 to pass through the baffle plate 23 and enter the cooling channel 122 through the air inlet of the cooling channel 122.

[0069] When the cooling fan 3 is working, the baffle plate 23 can block the cooling airflow generated by the cooling fan 3, so that more cooling airflow can flow to the scroll air compressor, thereby further reducing the loss of cooling airflow, improving the utilization rate of cooling airflow, and further improving the cooling efficiency of the scroll air compressor.

[0070] This application does not specifically limit the structure of the baffle plate 23; preferably, refer to... Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10 The baffle plate 23 includes a flow-blocking section 231 located on the side of the cooling fan 3 and a blocking section 232 located outside the flow-blocking section 231. The blocking section 232 and the flow-blocking section 231 are arranged at an angle.

[0071] Since the flow obstruction section 231 is located on the side of the cooling fan 3, it blocks the side of the cooling fan 3 to prevent the cooling airflow from flowing away from the side of the cooling fan 3 due to resistance. Since the blocking section 232 is located outside the flow obstruction section 231, it can block and guide the cooling airflow that flows to the outside of the cooling fan 3 due to resistance, so as to guide the cooling airflow to the scroll air compressor, thereby further improving the cooling efficiency of the scroll air compressor.

[0072] Preferably, the flow-blocking section 231 and the blocking section 232 are set at a 90° angle. That is, the flow-blocking section 231 is set parallel to the end face of the cooling fan 3, and the blocking section 232 is set perpendicular to the end face of the cooling fan 3, so as to increase the blocking and guiding effect on the cooling airflow.

[0073] In other embodiments, the baffle plate 23 also includes a flow guide section located between the flow obstruction section 231 and the baffle section 232. The cross-sectional shape of the flow guide section is arc-shaped to increase the guiding effect on the heat dissipation airflow, so as to avoid the formation of flow dead angles at the baffle plate 23 and further improve the heat dissipation effect on the scroll air compressor.

[0074] In a preferred embodiment, the baffle plate 23 is connected to the bracket 11 to increase the stability of the flow guiding assembly 2 and prevent noise from being generated due to the relative movement between the flow guiding assembly 2 and the scroll air compressor.

[0075] This application does not specify the connection method between the baffle plate 23 and the bracket 11, and it can adopt any of the following embodiments:

[0076] Implementation Example 1, in this implementation example, refer to Figure 3 , Figure 4 and Figure 5The flow-blocking section 231 is provided with a mounting hole 234, which is used to connect the flow guiding component 2 to the bracket 11.

[0077] Understandably, the baffle plate 23 is connected to the bracket 11 by screws passing through the mounting hole 234 and the bracket 11 or by a snap-fit ​​component that can engage with the bracket 11. On the one hand, this increases the stability of the flow guiding component 2 and avoids noise that may be generated by the relative movement of the flow blocking section 231 with the scroll air compressor. On the other hand, it reduces the assembly difficulty of the flow guiding component 2 and improves the assembly efficiency of the flow guiding component 2.

[0078] In this embodiment, the screws or clips used to fix the blocking section 232 can not only fix the blocking plate 23 to the bracket 11, but also pass through the cooling fan 3 to fix the cooling fan 3 to the bracket 11, thereby simplifying the structure of the scroll air compressor and improving the assembly efficiency of the scroll air compressor.

[0079] Preferably, the flow obstruction section 231 is provided with an extension plate extending inward, and the mounting hole 234 is provided on the extension plate, thereby ensuring that the flow obstruction section 231 can be located on the side of the cooling fan 3 to improve the obstruction effect on the cooling airflow.

[0080] Implementation Example 2, in this implementation example, refer to Figure 8 , Figure 9 and Figure 10 A fixing plate 233 is provided at the end of the baffle plate 23 away from the guide plate 22. The fixing plate 233 is provided with a mounting hole 234, which is used to connect the flow guiding component 2 to the bracket 11.

[0081] It is understood that the blocking plate 23 is connected to the bracket 11 by screws passing through the mounting hole 234 and the bracket 11 or by a snap-fit ​​device that can engage with the bracket 11, thereby connecting the blocking plate 23 to the bracket 11 to increase the stability of the blocking plate 23. At the same time, the fixing plate 233 can engage with the bracket 11 in the vertical upward direction to further increase the stability of the blocking plate 23.

[0082] In a preferred embodiment, refer to Figure 11 The vortex assembly 1 includes an air supply connector 15 and an air outlet connector 16. Multiple first heat dissipation channels 123 and multiple second heat dissipation channels 124 are formed between multiple heat dissipation fins 121. The air supply connector 15 and the air outlet connector 16 are located between the first heat dissipation channels 123 and the second heat dissipation channels 124. The first heat dissipation channels 123 are located close to the cooling fan 3 and the extension direction of the first heat dissipation channels 123 is parallel to the airflow direction of the cooling fan 3. The second heat dissipation channels 124 extend away from the air outlet connector 16 and are located away from the air supply connector 15.

[0083] It is understandable that the multiple heat dissipation fins 121 are divided into two groups. One group of heat dissipation fins 121 forms a first heat dissipation channel 123, and the other group of heat dissipation fins 121 forms a second heat dissipation channel 124. In other words, the heat dissipation channel 122 is composed of the first heat dissipation channel 123 and the second heat dissipation channel 124.

[0084] Since both the air supply connector 15 and the air outlet connector 16 are located between the first heat dissipation channel 123 and the second heat dissipation channel 124, the heat dissipation airflow flows through the first heat dissipation channel 123 to the air supply connector 15 and the air outlet connector 16 to dissipate heat from the air supply connector 15 and the air outlet connector 16. At the same time, the second heat dissipation channel 124 extends away from the air outlet connector 16 and is set away from the air supply connector 15, so that the heat dissipation airflow blown toward the air outlet connector 16 is discharged through the second heat dissipation channel 124, so as to avoid the situation where the heat dissipation airflow flowing toward the air outlet connector 16 is heated by the air outlet connector 16 and flows back toward the air supply connector 15, thereby preventing the intake air temperature of the scroll air compressor from rising.

[0085] This application does not specify the connection method between the cover plate 21 and the heat sink fins 121. Preferably, refer to... Figure 1 , Figure 4 , Figure 5 , Figure 9 and Figure 10 The cover plate 21 is provided with multiple connection holes 211 for screws to pass through, so that the cover plate 21 can be fixedly connected to the heat dissipation fins 121 by screws.

[0086] Since the cover plate 21 is provided with multiple connection holes 211 for screws to pass through, the cover plate 21 can be fixedly connected to the heat dissipation fins 121 by screws, thereby increasing the stability of the flow guiding assembly 2, reducing the assembly difficulty of the flow guiding assembly 2, and improving the assembly efficiency of the flow guiding assembly 2.

[0087] It should be noted that the aforementioned connecting hole 211, which is for screws to pass through, does not mean that it can only be used for screws; it can also be used for snap-fit ​​components that can be snapped into the heat sink fins 121.

[0088] In other embodiments, the cover plate 21 may also be connected to the heat dissipation fins 121 by welding or snap-fit ​​structure.

[0089] In a preferred embodiment, refer to Figure 4 , Figure 5 , Figure 9 , Figure 10 and Figure 11The cover plate 21 is provided with a through hole 212 through which the air supply connector 16 and the air supply connector 15 pass, so that the air supply connector 16 and the air supply connector 15 can pass through the cover plate 21, so as to facilitate the connection of external pipelines to the air supply connector 15 and the air supply connector 16. At the same time, it can also allow some of the heat dissipation airflow to flow through the first heat dissipation channel 123 to the air supply connector 16 and the air supply connector 15 and then be discharged through the through hole 212, thereby improving the heat dissipation effect on the air supply connector 15 and the air supply connector 16, reducing the flow resistance of the heat dissipation airflow in the first heat dissipation channel 123, and further improving the heat dissipation efficiency of the scroll air compressor.

[0090] This application does not impose specific limitations on the material used to manufacture the flow guiding component 2. Preferably, the flow guiding component 2 is made of a metal material with a high thermal conductivity, such as aluminum or copper alloys, to improve the heat dissipation efficiency of the scroll air compressor while ensuring the structural strength of the flow guiding component 2. In other embodiments, the flow guiding component 2 may also be made of other rigid materials, such as plastic.

[0091] In a preferred embodiment, refer to Figure 6 The vortex assembly 1 also includes a main unit 14 mounted on the bracket 11. The main unit 14 is used to drive the moving vortex 13 to rotate so that the moving vortex 13 and the stationary vortex 12 cooperate to compress the air.

[0092] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0093] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0094] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
