Description

Technical Field

[0001] The present application relates to the field of compressors, and in particular to a compressor assembly, a pneumatic brake device and a vehicle. Background Art

[0002] In the related technology, the scroll air compressor relies on the multi-point meshing of the scroll arms on the two scroll plates to form multiple crescent-shaped closed working volumes. Driven and restricted by the crankshaft and a special anti-rotation mechanism, the two scroll plates achieve relative orbital and translational motion, and the meshing points move continuously along the tooth walls. The crescent-shaped working chamber formed achieves periodic volume changes, thereby realizing the intake, compression and discharge of gas, and completing the compression and transportation of gas.

[0003] The scroll air compressor has the advantages of compact structure, high efficiency and energy saving, micro-vibration and low noise, and high reliability. However, when the scroll air compressor is working, a large amount of heat will be generated at the center of the scroll disk. Due to the structural characteristics of the scroll disk, the heat at the center of the scroll disk is not easy to dissipate to the outside. With the increase of working pressure and the increase of exhaust flow, the temperature of the center of the scroll disk also rises accordingly. The increase in temperature will cause the scroll disk to deform, and then cause a series of problems such as increased leakage, interference between the dynamic and static scroll disks, and increased power consumption of the whole machine. Therefore, how to improve the heat dissipation efficiency of the scroll air compressor has become a technical problem to be solved in this application. Summary of the invention

[0037] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0038] Reference below Figure 1-Figure 4 A compressor assembly 100 according to an embodiment of the present application is described.

[0039] The compressor assembly 100 according to the embodiment of the present application includes a first housing 1, a first plate 2, a second plate 3 and a third plate 4. A compression chamber 11 is formed in the first housing 1, and an air inlet 12 is arranged in the compression chamber 11. The first plate 2 is accommodated in the compression chamber 11 and divides the compression chamber 11 into a first chamber 111 and a second chamber 112. The first chamber 111 is connected to the air inlet 12. The first plate 2 is respectively provided with a first disk first vortex wall 21 and a first disk second vortex wall 22 on both sides in the thickness direction. The second plate 3 is arranged on the first plate 2. On one side in the thickness direction, the second disk 3 is provided with a second disk vortex wall 31 meshing with the first disk first vortex wall 21 for compressing the medium in the first cavity 111, and the second disk 3 is formed with a first cavity outlet 32 ​​communicating with the first cavity 111. The third disk 4 is arranged on the other side in the thickness direction of the first disk 2, and the third disk 4 is provided with a third disk vortex wall 41 meshing with the second vortex wall 22 of the first disk for compressing the medium in the second cavity 112. The third disk 4 is provided with a second cavity inlet 42, and the second cavity inlet 42 is communicated with the first cavity outlet 32.

[0040] A compression chamber 11 is formed in the first shell 1, and the first shell 1 provides physical protection for the internal components. The first disk 2 divides the compression chamber 11 into a first chamber 111 and a second chamber 112. The second disk 3 and the third disk 4 are respectively arranged on both sides of the first disk 2 in the thickness direction. The first disk first vortex wall 21 and the second disk vortex wall 31 are meshed to compress the medium in the first chamber 111, and the first vortex wall of the second disk 3 and the third disk vortex wall 41 are meshed to compress the medium in the second chamber 112, wherein the gas medium first enters the first chamber 111 through the air inlet 12, and after being compressed in the first chamber 111, is connected to the second chamber inlet 42 through the first chamber outlet 32, enters the second chamber 112, and undergoes secondary compression in the second chamber 112.

[0041] Since the first chamber 111 and the second chamber 112 are compressed separately, the heat generated by the first chamber 111 and the heat generated by the second chamber 112 are both smaller than the heat generated by the single-chamber compression in the related art. During the single-chamber compression, the compression work is concentrated in one chamber, and the heat generated by the gas during the compression process will be largely accumulated in the chamber and the center of the vortex disk connected thereto, resulting in concentrated heat that is difficult to dissipate. When the first chamber 111 and the second chamber 112 are compressed separately, the gas compression process is dispersed, and the degree of compression in each chamber is reduced compared to the single-chamber compression. According to the energy conversion principle, the amount of compression work converted into heat is also reduced accordingly, that is, the heat generated by the first chamber 111 and the second chamber 112 are each lower than the heat generated during the single-chamber compression, further reducing the overall heat dissipation burden.

[0042] At the same time, when the first cavity 111 and the second cavity 112 are compressed separately, the surface area used for heat dissipation is increased, which can better dissipate heat and improve the heat dissipation efficiency. Combined with the aforementioned reduction in heat dissipation of the first cavity 111 and the second cavity 112, the heat dissipation efficiency of the compressor assembly 100 can be more effectively improved, the stability and reliability of the compressor assembly 100 during operation can be ensured, various hidden dangers of failure caused by overheating can be reduced, the service life of the compressor assembly 100 can be extended, and it also helps to maintain the good working performance of the compressor assembly 100.

[0043] Furthermore, under good heat dissipation conditions, the internal temperature of the compressor assembly 100 is easier to control, and the adverse effects such as volume expansion of the gas caused by the increase in temperature during the compression process can be reduced, thereby achieving a higher degree of compression and a larger compression ratio; at the same time, due to the improved heat dissipation efficiency, the heat generated by the compressor assembly 100 when running at a high speed can be dissipated in time to avoid limiting the speed increase due to overheating, thereby increasing the exhaust volume per unit time, increasing the displacement of the compressor assembly 100, meeting more working conditions, and improving the overall performance and applicability of the compressor assembly 100.

[0044] In short, the gas is compressed by the first chamber 111 and the second chamber 112 respectively, and the gas is compressed by the two chambers, so that the heat generated by the first chamber 111 and the heat generated by the second chamber 112 are both less than the heat generated by the single chamber compression in the prior art. The heat generated by the first chamber 111 and the second chamber 112 is reduced, and the demand for heat dissipation intensity is reduced. At the same time, when the first chamber 111 and the second chamber 112 are compressed separately, the surface area for heat dissipation is increased, so that the first disk 2, the second disk 3 and the third disk 4 forming the first chamber 111 and the second chamber 112 can be better exposed to the external environment or the accessible range of the heat dissipation medium, which can improve the heat dissipation efficiency of the first chamber 111 and the second chamber 112, ensure the stability and reliability of the compressor assembly 100 during operation, and avoid the deformation of the first disk 2, the second disk 3 and the third disk 4 when overheated, resulting in increased leakage, interference between the first disk 2, the second disk 3 and the third disk 4, and increased power consumption of the whole machine, thereby extending the service life of the compressor.

[0045] According to some embodiments of the compressor assembly 100 of the present application, the first disk 2 is movably disposed in the first housing 1 to move relative to the second disk 3 and the third disk 4, and the first disk 2 drives the first disk first vortex wall and the first disk second vortex wall 22 to compress the medium in the first cavity 111 and the second cavity 112 respectively; or, the second disk 3 and the third disk 4 are respectively movably disposed in the first housing 1 to move relative to the first disk 2, and the second disk 3 drives the second disk vortex wall 31 to compress the medium in the first cavity 111, and the third disk 4 drives the third disk vortex wall 41 to compress the medium in the second cavity 112.

[0046] When the first disk 2 is movably arranged on the first housing 1 and moves relative to the second disk 3 and the third disk 4, the first disk 2 drives the first disk first vortex wall 21 and the first disk second vortex wall 22 to compress the medium in the first cavity 111 and the second cavity 112 respectively with the second disk vortex wall 31 and the third disk vortex wall 41, and the two cavities can be compressed at the same time. Since only the movement of the first disk 2 needs to be driven, the energy consumed for driving is reduced, which will significantly reduce the operating cost of the compressor during long-term operation.

[0047] When the second plate 3 and the third plate 4 are respectively movably arranged on the first shell 1 to move relative to the first plate 2, the second plate 3 drives the second plate vortex wall 31 to compress the medium in the first cavity 111, and the third plate 4 drives the third plate vortex wall 41 to compress the medium in the second cavity 112, so that the compression of each cavity is taken care of by the corresponding plate, and the two cavities can be operated independently or synchronously, thereby improving the adaptability and energy utilization efficiency of the entire compressor system.

[0048] In some embodiments of the present application, a seal is provided between the first plate 2 , the second plate 3 and the third plate 4 , and the seal is used to improve the sealing performance of the first cavity 111 and the second cavity 112 .

[0049] According to some embodiments of the present application, the compressor assembly 100 further includes a connecting pipe, which is arranged in the compression chamber 11 and is respectively connected to the second disk 3 and the third disk 4, and the two ends of the connecting pipe are respectively connected to the first chamber outlet 32 ​​and the second chamber inlet 42.

[0050] During the operation of the compressor, the gas that has completed the initial compression in the first chamber 111 can flow smoothly into the second chamber 112 through the connecting pipe for further compression, avoiding turbulence or backflow that may occur when the gas is transferred between the first chamber 111 and the second chamber 112, making the gas compression process more orderly and efficient. The orderly gas transfer can ensure that each compression stage can operate stably, improve the stability and reliability of the entire production process, and the connecting pipe can balance the pressure difference between the first chamber 111 and the second chamber 112. Since the pressure changes in different chambers are different during the compression process of the gas, the connecting pipe avoids pressure imbalance, which leads to a decline in the overall performance of the compressor and damage to components. The connecting pipe connects the first chamber 111 and the second chamber 112 to keep the pressure difference within a reasonable range, ensure the stable operation of the compressor, reduce equipment failures and downtime caused by pressure fluctuations, and reduce maintenance costs.

[0051] According to the compressor assembly 100 of some embodiments of the present application, a second cavity outlet 13 communicating with the second cavity 112 is provided on an axial end surface of the first shell 1 .

[0052] The second chamber outlet 13 is arranged on the axial end face of the first shell 1, which provides a discharge path for the compressed gas. The gas can leave the second chamber 112 in a relatively straight direction, reducing the flow resistance caused by turning, obstruction, etc. in the chamber. The smooth discharge path can ensure that the air can be transported out at a higher flow rate and in a stable state, thereby ensuring the efficient operation of the subsequent gas use links. Since the gas discharge path is more direct, the transfer from the second chamber 112 to the outside can be completed in a shorter time, thereby improving the exhaust efficiency of the entire compressor assembly 100. Under the same compression frequency and speed conditions, efficient exhaust means that more compressed gas can be discharged per unit time, thereby improving the working capacity of the compressor, achieving efficient exhaust, and avoiding production delays caused by poor exhaust.

[0053] According to the compressor assembly 100 of some embodiments of the present application, the second disk 3 is linked with the third disk 4 .

[0054] Furthermore, during the operation of the compressor assembly 100, the second disk 3 and the third disk 4 are linked. When the compressor starts working and the driving mechanism applies power, the linkage mechanism ensures that the second disk 3 and the third disk 4 maintain consistency in the start, rhythm and amplitude of the action when compressing the medium in the first chamber 111 and the second chamber 112. In each working cycle of the compressed gas, the second disk 3 and the third disk 4 will start the compression stroke at the same time and reach the node of the compression stroke at the same time, which can avoid the uncoordinated action that may occur due to their independent movements, making the compression process smoother and more orderly.

[0055] The linkage between the second disk 3 and the third disk 4 can make the compression process of the first chamber 111 and the second chamber 112 better coordinated to achieve a better compression ratio. Under the linkage effect, the two disks can allocate the degree of compression of the medium in their respective chambers according to the preset linkage relationship. The first chamber 111 can first perform preliminary, relatively low-pressure compression, and then through the linkage mechanism, the second chamber 112 can perform further, higher-pressure compression. The two cooperate with each other so that the medium can undergo a continuous and efficient compression process in the entire compressor assembly 100, thereby obtaining a higher overall compression ratio, which can more effectively meet production needs and improve product quality and production efficiency.

[0056] According to the compressor assembly 100 of some embodiments of the present application, a first flow channel 23 is formed inside the first disk 2, a second flow channel 33 is formed inside the second disk 3, and a third flow channel 43 is formed inside the third disk 4. The first flow channel 23, the second flow channel 33 and the third flow channel 43 are respectively suitable for circulating cooling medium.

[0057] When the compressor assembly 100 is running, the first disk 2, the second disk 3 and the third disk 4 will generate a large amount of heat during the compression process, especially the heat accumulation in the central parts of the first disk 2, the second disk 3 and the third disk 4. The first flow channel 23, the second flow channel 33 and the third flow channel 43 are respectively arranged inside the first disk 2, the second disk 3 and the third disk 4, and the cooling medium can directly approach various parts of the first disk 2, the second disk 3 and the third disk 4 for heat exchange. When the cooling medium flows through the first flow channel 23, it can take away the heat generated by the first disk 2 during the friction with the gas and the compression work. Similarly, the second flow channel 33 and the third flow channel 43 can also accurately cool the corresponding second disk 3 and the third disk 4, which can effectively prevent the first disk 2, the second disk 3 and the third disk 4 from deformation, wear and other problems due to overheating, and ensure the structural integrity and stability of the working performance of the first disk 2, the second disk 3 and the third disk 4, thereby maintaining the normal operation of the compressor and reducing the downtime and maintenance caused by component damage.

[0058] The existence of the first flow channel 23, the second flow channel 33 and the third flow channel 43 greatly increases the contact area between the cooling medium and the disk body. Compared with the method of relying solely on external heat dissipation, a faster and more efficient heat dissipation effect can be achieved. Since the cooling medium can circulate in the flow channel inside the disk and continuously bring out the heat, the heat will not accumulate inside the disk body. When the compressor is under high load and working for a long time, the gas is compressed frequently and intensively, and a lot of heat is generated. The cooling medium in the first flow channel 23, the second flow channel 33 and the third flow channel 43 can transfer the heat in time, so that the first disk 2, the second disk 3 and the third disk 4 are maintained within a reasonable operating temperature range, avoiding a series of adverse consequences caused by excessive temperature such as increased leakage, interference between the vortex moving and static disks, and increased power consumption of the whole machine, thereby extending the service life of the compressor assembly 100.

[0059] According to the compressor assembly 100 of some embodiments of the present application, the first flow channel 23, the second flow channel 33 and the third flow channel 43 are arranged in series or in parallel with each other.

[0060] When the first flow channel 23, the second flow channel 33 and the third flow channel 43 are connected in series, the cooling medium will flow through each flow channel in sequence. The cooling medium first enters the first flow channel 23, absorbs the heat generated by the first disk 2, and the temperature rises. Then, it enters the second flow channel 33 with this part of heat. At this time, it contacts the second disk 3 with a relatively lower temperature. Due to the temperature difference, the heat can be more efficiently transferred from the second disk 3 to the cooling medium, and then the cooling medium flows into the third flow channel 43 to continue heat exchange. This sequential flow forms a temperature gradient, so that the cooling medium can fully utilize the temperature difference between the disks with different temperatures to exchange heat during the entire flow process, optimize the efficiency of heat exchange, and more comprehensively and effectively take away the heat generated by each disk, ensuring that the first disk 2, the second disk 3 and the third disk 4 can all be maintained within a suitable operating temperature range.

[0061] When the first flow channel 23, the second flow channel 33 and the third flow channel 43 are connected in parallel with each other, the cooling medium can flow into each flow channel at the same time, and each flow channel has an independent heat dissipation path. Even if one of the flow channels is blocked, damaged, or the heat dissipation is abnormal due to other reasons, the other two flow channels can still work normally and continue to dissipate heat for the corresponding disk. The heat dissipation function of the entire compressor assembly 100 will not be completely invalid due to a problem in one flow channel, which greatly enhances the reliability of the heat dissipation system. If impurities accidentally enter a flow channel and affect the flow of the cooling medium, other parallel flow channels can maintain the heat dissipation of the corresponding disk, ensuring that the compressor can continue to operate stably for a period of time, avoiding shutdown caused by sudden overheating failures, and reducing production losses.

[0062] According to some embodiments of the present application, the compressor assembly 100 further includes a second shell 5 and an impeller 6. The second shell 5 is connected to the first shell 1. An impeller chamber 51 is formed in the second shell 5. The impeller chamber 51 is connected to at least one of the first flow channel 23, the second flow channel 33 and the third flow channel 43. The impeller 6 is rotatably disposed in the impeller chamber 51 and is suitable for driving the flow of cooling medium.

[0063] During the operation of the compressor assembly 100, the first disk 2, the second disk 3 and the third disk 4 will continuously generate heat, and the cooling medium needs to flow to take away the heat. The impeller 6 is rotatably arranged in the impeller cavity 51, and the impeller cavity 51 is connected to at least one of the first flow channel 23, the second flow channel 33 and the third flow channel 43. When the impeller 6 rotates, it can provide an active driving force for the cooling medium, so that the cooling medium can stably flow in the system composed of the first flow channel 23, the second flow channel 33 and the third flow channel 43 and the impeller cavity 51, which is different from the system that relies on natural convection. Compared with passively driving the flow by the cooling medium's own gravity or the like, the active driving of the impeller 6 enhances the flow velocity and flow rate of the cooling medium, so that the cooling medium can absorb the heat generated by the first disk 2, the second disk 3 and the third disk 4 more timely and fully, thereby improving the heat dissipation efficiency of the entire compressor assembly 100, ensuring that the first disk 2, the second disk 3 and the third disk 4 are within a reasonable operating temperature range, and effectively avoiding a series of problems such as deformation of the first disk 2, the second disk 3 and the third disk 4 and increased leakage caused by overheating, thereby ensuring the stable operation of the compressor.

[0064] According to some embodiments of the present application, the compressor assembly 100 further includes a third shell 7 and a rotor assembly 8. The third shell 7 is arranged between the first shell 1 and the second shell 5. The rotor assembly 8 is arranged in the third shell 7. One end of the rotor assembly 8 is connected to the first disk 2, and the other end of the rotor assembly 8 is connected to the impeller 6.

[0065] One end of the rotor assembly 8 is connected to the first disk 2, and the other end is connected to the impeller 6. The power transmission for driving the first disk 2 to work and driving the impeller 6 to operate is integrated into the same assembly. When an external power source drives the rotor assembly 8 to rotate, it can simultaneously drive the first disk 2 to perform gas compression and the impeller 6 to rotate to promote the circulation of the cooling medium in the flow channel, thereby realizing integrated power transmission, greatly simplifying the internal structure of the compressor assembly 100, reducing the use of numerous intermediate transmission components, and making the overall equipment more concise and compact.

[0066] Due to the simplification of the structure, the complexity of the equipment during installation is reduced accordingly. When assembling the compressor assembly 100, the staff does not need to spend a lot of time and energy to align and connect multiple scattered power transmission components, thereby improving the installation efficiency. At the same time, from a maintenance perspective, fewer components mean a relatively lower probability of failure, and when troubleshooting and performing repairs, the problem can be located more quickly and accurately, and the replacement of damaged parts is also more convenient, which reduces the time for equipment downtime and maintenance, reduces long-term maintenance costs, and improves the overall reliability and availability of the compressor assembly 100.

[0067] In some embodiments of the present application, the third shell 7 is arranged between the first shell 1 and the second shell 5, and a connecting column 71 is provided on the third shell 7, and the connecting column 71 is used to connect with the second shell 5. An air intake ring 72 is provided between the third shell 7 and the second shell 5, and the air intake ring 72 is arranged opposite to at least a part of the impeller 6. The cooling medium can be smoothly and evenly sucked into the impeller cavity 51 through the air intake ring 72 along this negative pressure area.

[0068] According to some embodiments of the compressor assembly 100 of the present application, the rotor assembly 8 includes a rotor shaft 81 and a stator 82. One end of the rotor shaft 81 forms an eccentric shaft segment 811 eccentrically arranged relative to the rotor shaft 81. The eccentric shaft segment 811 is connected to the first disk 2. The other end of the rotor shaft 81 is connected to the impeller 6. The stator 82 is arranged on the outer periphery of the rotor shaft 81 and is suitable for driving the rotor shaft 81 to rotate.

[0069] In the scroll compressor, the first disk 2 needs to perform specific relative revolution and translation to realize the gas suction, compression and discharge operations. The eccentric shaft segment 811 at one end of the rotor shaft 81 is connected to the first disk 2. The eccentric setting converts the rotational motion of the rotor shaft 81 into the eccentric motion of the first disk 2. When the stator 82 drives the rotor shaft 81 to rotate, the first disk 2 can perform relative revolution and translation according to the motion mode required by the scroll compressor through the action of the eccentric shaft segment 811, thereby ensuring that the gas realizes periodic rotation in the crescent-shaped working chamber formed by the first chamber 111 and the second chamber 112. The volume change of the first disk 2 is realized to complete the gas compression and transportation functions. In the actual operation process, the setting of the eccentric shaft end can accurately control the movement trajectory and speed of the first disk 2, ensuring that the gas can be effectively compressed to a predetermined pressure in each working cycle, and providing stable and qualified compressed gas for the subsequent gas use links. The other end of the rotor shaft 81 is connected to the impeller 6, which means that when the stator 82 drives the rotor shaft 81 to rotate, it can not only drive the first disk 2 to perform gas compression work, but also drive the impeller 6 to rotate, thereby realizing the coordinated operation of gas compression and cooling functions.

[0070] In some embodiments of the present application, an anti-rotation component is also provided. The anti-rotation component is arranged in the compression chamber 11 and is connected to at least one of the second disk 3 and the third disk 4, and is used to prevent the second disk 3 and the third disk 4 from rotating and affecting the compression effect of the compressor.
