Description

Technical Field

[0001] This invention relates to the field of reluctance motor technology, and particularly to reluctance motors and reluctance motors for compressor drives. Background Technology

[0002] As a type of high-efficiency and energy-saving motor, reluctance motors are widely used in various industrial scenarios such as compressor drives. Their operational stability and service life directly depend on the quality of their heat dissipation performance.

[0003] During the operation of a reluctance motor, both the stator and rotor generate a significant amount of heat. Currently, the traditional heat dissipation method for reluctance motors primarily involves setting up a cooling chamber inside the casing. Coolant is continuously circulated into this chamber, and its flow carries away the heat generated by the stator on the inner wall of the casing. This method is effective for stator cooling and can control the stator temperature relatively well. However, because the rotor is located inside the stator and is rotating, traditional cooling structures cannot effectively cool the rotor. The heat generated during rotor operation is difficult to dissipate quickly and tends to accumulate at the rotor, causing the rotor temperature to rise continuously. This, in turn, affects the overall operational stability and lifespan of the motor.

[0004] Therefore, a reluctance motor and a reluctance motor for driving a compressor are provided to address the above problems. Summary of the Invention

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0017] The positive and progressive effects of this invention are as follows: The aforementioned reluctance motor and reluctance motor for compressor drive, by setting heat dissipation mechanisms on both sides of the rotor and connecting the heat dissipation mechanism to the liquid delivery unit, and by using the rotor's rotation during motor operation to drive the liquid delivery unit to move synchronously, the liquid delivery unit can automatically draw coolant from the cooling chamber and input it into the heat dissipation mechanism. The coolant circulates in the heat conduction pipe of the heat dissipation mechanism, which can quickly absorb the heat transferred from the rotor to the heat conduction plate, and then carry the heat back to the cooling chamber, forming a circulation loop for rotor heat dissipation. This effectively solves the problem of heat being difficult to dissipate and easy to accumulate in the rotor of traditional reluctance motors, significantly reduces the rotor operating temperature, and ensures rotor operating stability.

[0018] The stator is cooled by an annular cooling chamber inside the housing, which quickly removes heat from the stator. The rotor is then cooled by a targeted cooling mechanism, achieving synchronous cooling of both the stator and rotor. In addition, the brush ring allows cooling liquid to be applied to the outer wall of the housing. The heat absorbed by the evaporation of the liquid further removes heat from the outer wall of the housing, widening the heat dissipation path and significantly improving the overall heat dissipation efficiency of the motor. This meets the heat dissipation requirements under high-load operating conditions and effectively prevents performance degradation and shortened lifespan of the motor due to overheating.

[0019] Furthermore, the infusion unit, injection mechanism, and pushing mechanism are all powered by the rotation of the motor shaft, eliminating the need for additional drive motors, pumps, or other power components. Specifically, the infusion unit uses the rotor's rotation to move the traveling column on the traveling surface, utilizing the cooperation of protrusions and springs to achieve automatic coolant extraction and delivery; the pushing mechanism uses a shaft to drive the end block to rotate, coordinating with springs to drive the brush ring to translate; the injection mechanism uses the reciprocating motion of the pushing mechanism to achieve automatic coolant suction and delivery. Through this design, there is no need to add multiple power sources for separate driving, reducing power supply and control wiring. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0023] like Figures 1-13 As shown, the reluctance motor includes a housing 1; a stator 10 and a rotor 11 are disposed inside the housing 1, and a rotating shaft 2 is fixed in the middle of the rotor 11.

[0024] A cooling chamber is provided inside the shell wall of the housing 1, and the cooling chamber is used for the flow of coolant.

[0025] Both sides of the rotor 11 are fixed with heat dissipation mechanisms 12, and one side of the heat dissipation mechanism 12 is provided with a liquid delivery part, which extends into the cooling chamber.

[0026] Multiple brush rings 6 are fitted on the outer wall of the housing 1. The brush rings 6 are connected to the liquid injection mechanism 8, and the brush rings 6 are connected to the pushing mechanism 7 through the connecting rod 9.

[0027] like Figures 1-6 As shown, the housing 1 includes a cylindrical body 101; a first end cap 102 and a second end cap 103 are fixed to both ends of the cylindrical body 101, respectively; the cylindrical body 101 is composed of an inner cylinder 1011 and an outer cylinder 1012, and an annular cooling chamber is formed between the inner cylinder 1011 and the outer cylinder 1012; a connecting ring 1013 is provided on both sides of the cooling chamber, and the connecting ring 1013 is fixed to the inner cylinder 1011 and the outer cylinder 1012; a plurality of evenly distributed through holes are provided on the connecting ring 1013. The inner cylinder 1011 and the outer cylinder 1012 are fixed together by the connecting ring 1013, and the through holes are provided for the passage of coolant.

[0028] Through the above design, the cylinder 101 of the housing 1 has an annular cooling cavity, and the stator 10 is fixed to the inner wall of the cylinder 101, that is, the inner wall of the inner cylinder 1011. The coolant flows through the cooling cavity, and the heat generated by the stator 10 is transferred to the coolant in the cooling cavity through the inner cylinder 1011, thereby realizing the heat dissipation of the stator 10.

[0029] like Figures 1-2 As shown, the first end cap 102 and the second end cap 103 are respectively fixed with an inlet pipe 4 and a drain pipe 5; the inlet pipe 4 and the drain pipe 5 are respectively connected to both sides of the cooling chamber. The inlet pipe 4 is used to input coolant, so that the coolant enters one side of the cooling chamber, and after the coolant flows in the cooling chamber, it is discharged from the drain pipe 5.

[0030] It should also be noted that the rotating shaft 2 passes through the middle of the first end cover 102 and extends out of the housing 1.

[0031] like Figures 4-6As shown, the heat dissipation mechanism 12 includes a heat-conducting disk 1201 fixed to the side wall of the rotor 11; a heat-conducting pipe 1202 is provided inside the heat-conducting disk 1201, and the heat-conducting pipe 1202 is a vortex tube; the two ends of the heat-conducting pipe 1202 are respectively fixedly connected to an outlet pipe 1203 and an inlet pipe 1204; a rotating ring 1205 is rotatably installed on the inner wall of the housing 1, and a first interface 1206 and a second interface 1207 are respectively provided on both sides of the rotating ring 1205. The first interface 1206 is fixedly connected to the outlet pipe 1203 and to the cooling chamber. The inlet pipe 1204 is fixedly sleeved with the second interface 1207 and is connected to the liquid delivery part.

[0032] An annular groove is provided between the first end cap 102 and the inner cylinder 1011, and between the second end cap 103 and the inner cylinder 1011. The annular groove communicates with the cooling chamber. The rotating ring 1205 is disposed in the annular groove to achieve rotatable installation. A sealing ring 1208 is provided on the rotating ring 1205. The sealing ring 1208 provides a seal for the installation position of the rotating ring 1205, preventing the coolant in the cooling chamber from leaking into the housing 1 through the annular groove.

[0033] like Figure 5 , Figure 7 as well as Figure 8 As shown, the infusion unit includes a movable cylinder 1209 slidably installed within the second interface 1207. One end of the movable cylinder 1209 extends into the cooling chamber. A second piston 1213 is fitted inside the movable cylinder 1209. The second piston 1213 is fixed to the end of the inlet pipe 1204 (i.e., the end of the inlet pipe 1204 away from the heat-conducting pipe 1202, and the inlet pipe 1204 passes through a hole on one side of the movable cylinder 1209). A fourth one-way valve 1214 is installed at the end of the inlet pipe 1204 (the side of the piston away from the inlet pipe 1204 is fixed to the movable cylinder 1209). The inner walls of the 09 form an infusion chamber, with one end of the fourth one-way valve 1214 connected to the infusion chamber. A third one-way valve 1210 is fixedly installed at one end of the movable cylinder 1209 located within the cooling chamber, and a traveling column 1211 is fixed at the same end. An annular traveling surface is provided on the wall of the cooling chamber, and one end of the traveling column 1211 abuts against this surface. A second spring 1215 is installed inside the second interface 1207, with both ends abutting against the inner wall of the second interface 1207 and the end face of the movable cylinder 1209, respectively. A second ball bearing 1212 is provided at the end of the traveling column 1211, directly contacting the traveling surface. As the traveling column 1211 moves along the traveling surface, rolling friction is provided by the ball bearing.

[0034] like Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, the walking surface is the inner wall of the outer cylinder 1012; multiple protrusions 13 are fixed on the walking surface in a circular array, and a ramp surface 1301 is provided on both sides of the protrusions 13, and an arc surface is provided between the two ramp surfaces 1301.

[0035] The rotor 11 can be cooled by providing a heat dissipation mechanism 12 and an infusion section.

[0036] During the operation of the motor, the rotor 11 drives the heat dissipation mechanism 12 and the infusion section to rotate together. The traveling column 1211 of the infusion section moves along the traveling surface and moves to the protrusion 13. The traveling column 1211 climbs up the slope 1301 on one side to the arc-shaped surface, and then descends from the slope 1301 on the other side to the position between the protrusions 13. During the climbing process of the traveling column 1211, the traveling column 1211 drives the movable cylinder 1209 to move into the second interface 1207 and compresses the second spring 1215. The second piston 1213 pushes the coolant in the movable cylinder 1209 (i.e., in the infusion chamber), so that the coolant is input into the inlet pipe 1204 through the fourth one-way valve 1214. Then it passes through the heat pipe 1202 and finally drains back into the cooling chamber through the outlet pipe 1203 and the first interface 1206. During the descent of the walking column 1211, the movable cylinder 1209 is reset by the elastic force of the second spring 1215. The movable cylinder 1209 draws coolant from the cooling chamber through the third one-way valve 1210, so that the coolant is replenished into the delivery chamber. The protrusions 13 are arranged in a ring array. When the rotor 11 continues to rotate, the walking column 1211 passes through all the protrusions 13 and the positions between the protrusions 13 (a depression is formed between adjacent protrusions 13). The delivery section reciprocates to inject coolant and replenish coolant into the heat pipe 1202 so that the coolant can automatically continue to pass through the heat pipe 1202.

[0037] Both the heat pipe 1202 and the heat plate 1201 are made of thermally conductive materials, such as metallic copper. Thermally conductive silicone is placed between the heat plate 1201 and the rotor 11.

[0038] The heat generated by the rotor 11 is transferred to the heat conduction plate 1201 and absorbed by the coolant flowing in the heat conduction pipe 1202, thereby achieving cooling and heat dissipation of the rotor 11.

[0039] The above design facilitates the flow of coolant through the heat pipe 1202 in the heat dissipation mechanism 12, thereby ensuring the cooling effect on the rotor 11. At the same time, the fluid delivery unit is powered by the rotation of the rotor 11, eliminating the need for an additional power source and solving the problem of inconvenient electrical wiring under rotating conditions.

[0040] like Figure 1 and Figure 13As shown, the brush ring 6 includes a ring body 601; brush bristles 602 are fixed on the inner ring of the ring body 601, the brush bristles 602 are attached to the outer wall of the housing 1, the ring body 601 is provided with a circular inner cavity 603, and the inner ring of the ring body 601 is provided with a plurality of drainage holes 604 arranged in a ring array, and the drainage holes 604 are connected to the inner cavity 603; the connecting rod 9 is provided with a communicating cavity, and a short tube 902 connected to the communicating cavity is fixed on the connecting rod 9, and the short tube 902 is fixed to the bottom of the ring body 601, and the short tube 902 is connected to the inner cavity 603; the connecting rod 9 is also provided with a connecting port 901, and the connecting port 901 is connected to the communicating cavity, and the connecting port 901 is connected to the injection mechanism 8.

[0041] To further improve the cooling effect of the entire motor, the pushing mechanism 7 drives the brush ring 6 to reciprocate on the outer wall of the housing 1 via the connecting rod 9, and the liquid injection mechanism 8 injects cooling liquid (such as pure water) into the connection port 901. The liquid is input into the inner cavity 603 through the connecting cavity and the short pipe 902, and then discharged from the drain hole 604, so that the brush bristles 602 absorb the liquid. The brush ring 6 moves on the outer shell, so that the liquid is brushed onto the outer wall of the housing 1 to form a water film. The water film evaporates, providing cooling for the housing 1 and improving the cooling effect.

[0042] like Figure 9 , Figure 10 as well as Figure 12 As shown, the injection mechanism 8 includes a fixed cylinder 801 fixed to one side of the housing 1 (i.e., the outer side of the second end cap 103); a first piston 802 is fitted inside the fixed cylinder 801, and a movable column 803 is fixed to the first piston 802, and the movable column 803 is connected to the pushing mechanism 7; a first spring 804 is provided inside the fixed cylinder 801; one end of the inner wall of the fixed cylinder 801 is elastically connected to one side of the first piston 802 through the first spring 804; an injection chamber is formed between one side of the first piston 802 and the inner wall of the fixed cylinder 801; a first one-way valve 805 and a second one-way valve 806 are fixed to the top and bottom of the fixed cylinder 801, respectively, and one end of the first one-way valve 805 and one end of the second one-way valve 806 are both connected to the injection chamber; the second one-way valve 806 is connected to a connecting pipe 807, and the connecting pipe 807 is connected to a spiral hose 808; one end of the spiral hose 808 is fixedly connected to a connecting port 901.

[0043] like Figures 10-11As shown, the pushing mechanism 7 includes a cylinder 701 fixed to the middle of one side of the housing 1 (i.e., the middle of the second end cover 103); the cylinder 701 is rotatably connected to one end of the rotating shaft 2, and an end block 705 is fixed to the end of the rotating shaft 2, and the end block 705 is disposed inside the cylinder 701. A guide hole is opened at one end of the cylinder 701, and a movable rod 703 is slidably fitted in the guide hole. A side column 706 is fixed to one end of the movable rod 703, and a first ball bearing 707 is provided at one end of the side column 706. A connecting frame 704 is fixed to the movable rod 703, and the connecting frame 704 is fixed to the movable column 803 and the end of the connecting rod 9.

[0044] like Figure 11 As shown, the end block 705 is provided with a pressing slope 7051 on the side away from the rotating shaft 2, and the pressing slope 7051 abuts against the first ball 707.

[0045] The first check valve 805 of the liquid injection mechanism 8 is connected to an external container for storing cooling liquid via a pipe. When the motor is running, the rotating shaft 2 drives the end block 705 to rotate together. The end block 705 squeezes the first ball 707 through the squeezing inclined surface 7051 and, in conjunction with the elastic force of the first spring 804, causes the side column 706, movable rod 703, connecting frame 704, connecting rod 9, brush ring 6 and movable column 803 to move back and forth together. This causes the brush ring 6 to move back and forth on the outer wall of the housing 1. The movable column 803 drives the first piston 802 to move left and right together. When the first piston 802 moves away from the second end cover 103, the fixed cylinder 801 draws in the liquid. The external cooling liquid enters the injection chamber through the first one-way valve 805. The first piston 802 approaches the second end cover 103 and squeezes the liquid in the injection chamber. The liquid passes through the second one-way valve 806, connecting pipe 807, spiral hose 808, connecting port 901, connecting cavity, short pipe 902 and then enters the inner cavity 603 of the brush ring 6.

[0046] With the above design, the pushing mechanism 7 and the liquid injection mechanism 8 are powered by the rotation of the rotating shaft 2, which drives the end block 705 to rotate. The translation of the brush ring 6 on the housing 1 to brush the cooling liquid and the liquid input do not require additional power.

[0047] The spiral hose 808 is designed to accommodate the translational movement of the connecting rod 9, ensuring that the connection port 901 remains connected to the injection mechanism 8 during the movement of the connecting rod 9. Specifically, the spiral hose 808 is stretched or contracted by the translational movement of the connecting rod 9 to maintain the aforementioned constant connection.

[0048] The movable rod 703 is provided with a corrugated sleeve 702. One end of the inner wall of the corrugated sleeve 702 is fixedly sleeved to the movable rod 703, and the other end of the corrugated sleeve 702 is fixed to the outside of the guide hole. The corrugated sleeve 702 is used to seal the guide hole, preventing dust and foreign objects from entering the gap between the guide hole and the movable rod 703. Furthermore, the corrugated sleeve 702 is telescopic, suitable for the translational movement requirements of the movable rod 703.

[0049] The bottom of the housing 1 is fixed with a base 3, and a side groove 301 is provided on one side of the base 3. The connecting rod 9 and the spiral hose 808 both pass through the side groove 301.

[0050] The aforementioned reluctance motor is applied to a compressor. The rotating shaft 2 of the reluctance motor is connected to the scroll drive main shaft of the compressor. The reluctance motor drives the scroll drive main shaft of the compressor to rotate via the rotating shaft 2, thereby driving the compressor. By improving the heat dissipation and cooling performance of the reluctance motor, operational stability and service life are ensured.
