Description

Technical Field

[0001] The present invention relates to the field of magnetic levitation compressors, and particularly to a structure of an air-conditioning magnetic levitation compressor. Background Art

[0002] With the development of electronic technology, control engineering, signal processing components, electromagnetic theory and new electromagnetic materials, as well as the progress of rotor dynamics, magnetic levitation technology has made great progress in recent years. Magnetic levitation utilizes the principle of "like poles repel, opposite poles attract" of magnetism. An appropriate electromagnetic field is applied between the rotor and stator of the bearing, and by controlling the electromagnetic field, the rotor can be in a relatively "levitated" state.

[0003] A magnetic levitation system consists of four parts: a rotor, a sensor, a controller, and an actuator. The actuator includes an electromagnet and a power amplifier. A magnetic levitation bearing uses a magnetic field to levitate the rotor, so that there is no mechanical contact and no mechanical friction during rotation, and there is no longer a need for a mechanical bearing and the lubrication system necessary for the mechanical bearing. When a magnetic levitation bearing is used in a refrigeration compressor, all the troubles caused by lubricating oil no longer exist.

[0004] A magnetic levitation refrigeration compressor is a new type of compressor using the above-mentioned magnetic levitation bearing, which has many advantages compared with ordinary compressors. For example, it has high operating efficiency, 30% higher than that of traditional compressors; high adaptability, which can meet the cooling demand throughout the day; and redefines soft start, only requiring a starting current of 2 amperes, while traditional compressors require 500 - 600 amperes.

[0005] However, the magnetic levitation system needs to use a winding electromagnet. To ensure small axial and radial runout, the current in the coil of the magnetic levitation system needs to be changed frequently. Therefore, a large number of coils generate heat during operation. When the compressor runs at tens of thousands of revolutions per minute, if the heat cannot be removed in time, it may cause a fire inside the compressor.

[0006] The prior art also has the following deficiencies: When a traditional compressor is cooled, heat dissipation holes are opened in the motor cylinder, and the heat generated by the internal parts of the magnetic levitation motor is conducted to the heat dissipation holes through the gaps between the parts and then the heat is discharged. In this way, the heat is spontaneously conducted to the heat dissipation holes along the gaps between the parts, and there is no heat dissipation channel to guide the heat inside the compressor, reducing the heat dissipation efficiency of the compressor. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the present invention provides a structure of an air-conditioning magnetic levitation compressor, which solves the problems put forward in the above background art.

[0008] To achieve the above object, the present invention is realized through the following technical solutions: A structure of an air-conditioning magnetic levitation compressor includes a reflux cooling cover and a magnetic levitation motor body.

The suspension components are used to keep the main shaft suspended, and the air flow components can achieve air intake from the compression component seat when the main shaft is running. The intake air passes through the intersection of the main shaft and the reflux cooling cover and then passes through the inside of the magnetic levitation motor body, and then is reflected by the reflecting cover and finally discharged from the air outlet holes.

[0010] Preferably, the suspension components include a permanent magnet group installed on the main shaft, and annular grooves are provided on both sides of any permanent magnet group on the outer ring of the main shaft.

[0011] The suspension components further include an electromagnet group and an outer cover. There are multiple electromagnet groups, all of which are fixed in the outer cover. The main shaft passes through the outer cover, and there is an annular gap between the two. The electromagnet groups are distributed around the outer ring of the permanent magnet group.

[0012] Preferably, the air flow components include two groups of turbine blades. One group of turbine blades is fixed in a ring on the inner wall of the groove. The two groups of turbine blades corresponding to one permanent magnet group are opposite in direction and are both arranged in a conical shape. The height of the large end of the cone of the turbine blade corresponds to the outer wall of the permanent magnet group, and the height of the small end of the cone of the turbine blade corresponds to the outer wall of the main shaft.

[0013] Preferably, horn-shaped covers communicated with the inside are fixedly installed on both the left and right sides of the outer cover, and one group of turbine blades is located in one horn-shaped cover.

[0014] Preferably, the permanent magnet group includes multiple arc-shaped permanent magnet tiles, and the permanent magnet tiles are fixedly arranged around the main shaft at equal distances.

[0015] The electromagnet group includes an arc-shaped pole piece and multiple windings. One end of each of the multiple windings is fixed to the arc-shaped pole piece, and the other end is fixed to the inner wall of the outer cover.

[0016] The arc-shaped pole piece and the permanent magnet tiles are concentrically arranged.

[0017] Preferably, the magnetic levitation motor body further includes two groups of rotors. The rotors are sleeved on the main shaft. A balance frame capable of allowing air to pass through left and right is fixedly installed on the inner ring of the rotors. The balance frame is fixedly sleeved on the main shaft. Any one group of rotors is located between two adjacent suspension components, and the balance frame corresponds to the left and right horn-shaped covers respectively.

[0018] Preferably, the magnetic levitation motor body also includes two axial stabilization components located at both ends of the main shaft, the axial stabilization components include a gyroscope disk and a stabilization cover, the gyroscope disk is fixedly mounted on the main shaft, the left and right sides of the gyroscope disk are both arc surfaces, and permanent magnets are attached to the arc surfaces, the stabilization cover covers the outside of the gyroscope disk, a circle of electromagnets is fixed inside the stabilization cover, and there is an annular gap between the stabilization cover and the main shaft.

[0019] Preferably, the magnetic levitation motor body also includes a clamping assembly installed on the main shaft, the clamping assembly includes a flying disc and a plurality of electromagnetic telescopic rods distributed around the flying disc, the output ends of the electromagnetic telescopic rods are all equipped with balance wheels, the flying disc is fixed on the main shaft, and the electromagnetic telescopic rods can be extended at the same time to make the balance wheel rest on the rim of the flying disc.

[0020] Preferably, the magnetic levitation motor body further comprises a motor housing, and the outer cover, the stabilizing cover and the electromagnetic telescopic rod are all fixed on the motor housing, the two ends of the motor housing are open structures, and a circle of heat sinks is fixed to the outer ring of the motor housing.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The structure of the air-conditioning magnetic levitation compressor is provided with a reflux cooling cover and an airflow component. When the main shaft rotates, the compressor can be driven to operate. In this process, the rotation of the turbine blades contained in the airflow component can realize a linear airflow movement. When it rotates at a high speed, it can inhale airflow from the external position of the main shaft. The inhaled airflow can act on the electromagnet group and finally be discharged through the end of the magnetic levitation motor body. After being discharged, it is returned through the reflection cover, and then the heat emitted from the motor casing and the heat inside the reflux cooling cover are taken out through the air outlet, which can realize the heat dissipation of all internal and external parts at one time. Moreover, the turbine blades fit the main shaft and have a small diameter, so they have little effect on the high speed of the main shaft. The inhaled airflow is in the form of a flow surrounding the main shaft, so the high speed of the main shaft is affected by a small airflow component. Therefore, high speed operation can be achieved without affecting the speed.

[0023] 2. The structure of the air conditioner magnetic levitation compressor has a hollow balance frame, so that part of the airflow can pass through the balance frame, and the airflow that cannot pass through the balance frame will surround the rotor and take away the heat of the coil on the inner wall of the motor housing.

[0024] 3. The structure of the air-conditioning magnetic levitation compressor is provided with an axial stabilization component, which can prevent the axial movement of the main shaft and also provides a gap for airflow to pass through, which does not affect the movement of the airflow and the internal heat can also be taken away by the airflow.

[0025] 4. The structure of the magnetic levitation compressor of this air conditioner, by setting the clamping component, the flywheel does not affect the air flow, and the main shaft can remain suspended when the voltage, current is unstable or there is a power outage. Description of the Drawings

[0040] In addition, in the present application, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.

[0041] As Figures 1-10 shown, a structure of an air-conditioning magnetic levitation compressor includes a reflux cooling cover 1 and a magnetic levitation motor body 2. One end of the reflux cooling cover 1 is provided with a hollowed-out compression component seat 3. Matrix-distributed air outlet holes 4 are provided on the side surface of the reflux cooling cover 1 corresponding to the compression component seat 3. The magnetic levitation motor body 2 is installed in the reflux cooling cover 1. The magnetic levitation motor body 2 includes a main shaft 5. The main shaft 5 passes through the reflux cooling cover 1, and there is an annular gap between the two. A reflection cover 6 is fixed on the inner wall of the reflux cooling cover 1 corresponding to the end of the magnetic levitation motor body 2 far from its main shaft 5.

[0042] The magnetic levitation motor body 2 further includes multiple sets of levitation components 7 and airflow components 8. The levitation components 7 are used to keep the main shaft 5 levitated. When the main shaft 5 is operating, the airflow components 8 can intake air from the compression component seat 3. The intake air passes through the intersection of the main shaft 5 and the return cooling cover 1 and then passes through the inside of the magnetic levitation motor body 2. After that, it is reflected by the reflection cover 6 and finally discharged from the air outlet holes 4.

[0043] In traditional equipment, generally, the magnetic levitation motor body 2 is directly connected to the compressor to achieve the operation of the compressor. However, the magnetic levitation motor body 2 generates a large amount of heat, which is not conducive to the long-term operation of the equipment. And adding air cooling and water cooling to it both require the use of additional equipment. Some heat dissipation equipment will limit the rotation speed of the magnetic levitation shaft, and some peripherals are not conducive to the placement in the specific installation area. Therefore, using its own characteristics to achieve heat dissipation will obtain better effects.

[0044] The return cooling cover 1 is an integral metal cover. All the air outlet holes 4 are concentrated on the left side of the return cooling cover 1 and are distributed around the return cooling cover 1 in a circle. Circular holes are drilled at the positions of the return cooling cover 1 corresponding to the main shaft 5. The diameter of the circular holes is larger than the diameter of the main shaft 5. The reflection cover 6 is at the other end of the main shaft 5. The reflection cover 6 is a horn-shaped structure with an opening facing the tail of the magnetic levitation motor body 2.

[0045] When the magnetic levitation motor body 2 is operating, it can inhale air from the extending end of the main shaft 5, and then it is reflected by the reflection cover 6. Finally, after filling the inside of the entire return cooling cover 1, it is discharged from the air outlet holes 4. The airflow discharged from the air outlet holes 4 can take out the heat inside the return cooling cover 1.

[0046] In an optional embodiment, the levitation component 7 includes a permanent magnet group 701 installed on the main shaft 5. Annular grooves are provided on both sides of any permanent magnet group 701 on the outer circle of the main shaft 5.

[0047] The levitation component 7 further includes an electromagnet group 702 and an outer cover 703. There are multiple electromagnet groups 702, all of which are fixed inside the outer cover 703. The main shaft 5 passes through the outer cover 703, and there is an annular gap between the two. The electromagnet group 702 is distributed around the outer circle of the permanent magnet group 701.

[0048] In this embodiment, at one position on the main shaft 5 where the permanent magnet group 701 is installed, two convex rings are machined by a machine tool. The permanent magnet group 701 is located between the two convex rings. The annular grooves are also turned out by a machine tool. However, the annular grooves are divided into a flat part and an inclined part. The flat part corresponds to the permanent magnet group 701, and the inclined part extends gently outwards.

[0049] The outer cover 703 is a circular ring with a cavity, and there are round holes on both sides. The round holes correspond to the convex rings, and there is also a space between the round holes and the above-mentioned convex rings. The electromagnet group 702 is evenly distributed around the cavity of the outer cover 703 in a circular manner.

[0050] In an alternative embodiment, the air flow assembly 8 includes two sets of turbine blades 801. One set of turbine blades 801 is fixedly arranged in a circular shape on the inner wall of the groove. The two sets of turbine blades 801 corresponding to one permanent magnet group 701 are opposite in direction and are both arranged in a conical shape. The height of the large end of the cone of the turbine blade 801 corresponds to the outer wall of the permanent magnet group 701, and the height of the small end of the cone of the turbine blade 801 corresponds to the outer wall of the main shaft 5.

[0051] In this embodiment, the turbine blade 801 is triangular and all have the same inclination angle, which is used to compress the air flow in one direction when rotating. However, the height of the turbine blade 801 needs to be simulated and calculated. Generally, when the rotational speed is above 10,000 revolutions per minute, the turbine blade 801 needs to be lower than the height of the convex ring to avoid the rotational speed being limited due to compressed gas. When the left and right sets of turbine blades 801 rotate in one direction around the main shaft 5, an air flow can be realized to move along the direction.

[0052] In an alternative embodiment, horn-shaped covers 704 that communicate with the inside are fixedly installed on both the left and right sides of the outer cover 703, and one set of turbine blades 801 is located inside one horn-shaped cover 704.

[0053] In this embodiment, the horn-shaped cover 704 mainly cooperates with the turbine blade 801 to better compress the air by the turbine blade 801.

[0054] In an alternative embodiment, the permanent magnet group 701 includes a plurality of arc-shaped permanent magnet tiles 7011, and the permanent magnet tiles 7011 are evenly distributed and fixed around the main shaft 5 in a circular manner;

[0055] The electromagnet group 702 includes an arc-shaped pole piece 7021 and a plurality of windings 7022. One ends of the plurality of windings 7022 are all fixed to the arc-shaped pole piece 7021, and the other ends are fixed to the inner wall of the outer cover 703;

[0056] The arc-shaped pole piece 7021 and the permanent magnet tile 7011 are concentrically arranged.

[0057] In this embodiment, the permanent magnet tile 7011 is made of a strong magnetic and permanent magnetic material such as a rubidium magnet. The windings 7022 connecting an arc-shaped pole tile 7021 are arranged at equal distances. The iron core inside the windings 7022 is connected to the arc-shaped pole tile 7021. The magnetism generated by the windings 7022 can act on the arc-shaped pole tile 7021 together. However, setting multiple windings 7022 can make the magnetic force generated by the arc-shaped pole tile 7021 more stable. Moreover, when changing the current of different windings 7022, the distribution of magnetism can be controlled more accurately. When the main shaft 5 rotates at a high speed, the algorithm can be better utilized to control the stability of the rotation of the main shaft 5.

[0058] In an alternative embodiment, the magnetic levitation motor body 2 further includes two groups of rotors 9. The rotors 9 are sleeved outside the main shaft 5. A balance frame 10 capable of allowing air flow to pass through left and right is fixedly installed on the inner ring of the rotor 9. The balance frame 10 is fixedly sleeved on the main shaft 5. Any one group of rotors 9 is located between two adjacent suspension components 7. The balance frame 10 corresponds to the left and right horn covers 704 respectively.

[0059] In this embodiment, compared with the prior art, the structure of the balance frame 10 is added, which can not only ensure the stable and balanced connection of the rotor 9, but also enable the air flow to pass through.

[0060] In an alternative embodiment, the magnetic levitation motor body 2 further includes two axial stability components 11 at both ends of the main shaft 5. The axial stability components 11 include a gyroscope disk 1101 and a stability cover 1102. The gyroscope disk 1101 is fixedly sleeved on the main shaft 5. The left and right side surfaces of the gyroscope disk 1101 are both arc-shaped, and permanent magnets are attached to the arc surfaces. The stability cover 1102 covers the gyroscope disk 1101. A ring of electromagnets is fixed inside the stability cover 1102. There is an annular gap between the stability cover 1102 and the main shaft 5.

[0061] In this embodiment, the structures of the gyroscope disk 1101 and the stability cover 1102 are the same as the principle of the suspension component 7, and both use electromagnetic repulsion to achieve axial stability control. However, setting the gyroscope disk 1101 can enable the air flow to pass through, so that any heated area can be cooled.

[0062] In an alternative embodiment, the magnetic levitation motor body 2 further includes a clamping component 12 installed on the main shaft 5. The clamping component 12 includes a flying disk 1201 and a plurality of electromagnetic telescopic rods 1202 distributed around the flying disk 1201. The output ends of the electromagnetic telescopic rods 1202 are all installed with balance wheels 1203. The flying disk 1201 is fixed on the main shaft 5. The electromagnetic telescopic rods 1202 can extend simultaneously so that the balance wheels 1203 abut against the rim of the flying disk 1201.

[0063] In this embodiment, all electromagnetic telescopic rods 1202 are controlled by one control module. When the power is off or the voltage is unstable, the control chip can transmit a signal to make all electromagnetic telescopic rods 1202 extend instantly together.

[0064] In an optional embodiment, the magnetic levitation motor body 2 also includes a motor housing 13, and the outer cover 703, the stabilizing cover 1102 and the electromagnetic telescopic rod 1202 are all fixed on the motor housing 13. The two ends of the motor housing 13 are open structures, and a circle of heat sinks 14 is fixed to the outer ring of the motor housing 13.

[0065] In this embodiment, the heat sink 14 is used to dissipate the heat of the internal coil.

[0066] When in use, the magnetic levitation motor body 2 is energized, and the coil can drive the rotor 9 and the main shaft 5 to rotate. When the main shaft 5 rotates, the compressor can be driven to operate. In this process, the rotation of the turbine blades 801 included in the airflow component 8 can drive the linear motion of the airflow. The turbine blades 801 cooperate with the horn cover 704 to achieve a better compressed gas effect, and can strongly promote the operation of the airflow. When it rotates at a high speed, it can inhale the airflow from the external position extending from the main shaft 5. The inhaled airflow passes through the axial stabilization component 11 and the clamping component 12 respectively, and can act on the electromagnet group 702 to remove the heat of the main heat source, and finally be discharged through the end of the magnetic levitation motor body 2, taking away the heat generated by all internal heat sources at one time. The discharged hot air is returned by the reflective cover 6, and then the heat emitted by the motor housing 13 and the heat inside the reflux cooling cover 1 are taken out through the air outlet 4, which can achieve complete heat dissipation of internal and external parts at one time.
