Description

Technical Field

[0001] This invention belongs to the field of permanent magnet motor technology, specifically a permanent magnet motor assembly with a heat dissipation mechanism. Background Technology

[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a magnetic field. The speed of its rotor is consistent with the current frequency of the stator winding. The core structure of a permanent magnet motor is similar to that of a traditional motor, consisting of components such as a stator, rotor, and end caps. The stator is basically the same as that of an ordinary induction motor, and adopts a laminated structure to reduce iron loss during motor operation.

[0003] Permanent magnet motors can only be cooled by air or liquid, and the two cannot be combined. A single cooling method is not very effective and affects the final cooling effect of the permanent magnet motor. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a permanent magnet motor assembly with a heat dissipation mechanism, including a base plate, and further comprising: The cooling mechanism is set on the base plate and the motor body installed inside the cooling mechanism, the auxiliary mechanism is above the cooling mechanism and the liquid outlet pipe is installed outside the auxiliary mechanism; The cooling mechanism includes a housing mounted on the base plate, heat dissipation pipes disposed outside the motor body, a gap cleaning assembly disposed in the gaps between the heat dissipation pipes, and an end face cooling assembly mounted on one end of the motor body.

[0005] Furthermore, the cooling mechanism also includes: A dustproof plate, which is installed at one end of the housing; The first connecting pipe is installed at the end of the heat dissipation pipe away from the dustproof plate; The second connecting pipe is installed at one end of the heat dissipation pipe near the dustproof plate. The first connecting pipe and the second connecting pipe are staggered on both sides of the heat dissipation pipe, so that multiple heat dissipation pipes on the outside of the motor body are connected in an arc shape around the outside of the motor body, so that the coolant can cover the circular surface of the motor body.

[0006] Furthermore, the auxiliary mechanism includes: A coolant tank, which is mounted on top of the housing; A heat insulation block is installed at the bottom of the coolant tank, dividing the coolant tank into two spaces. The larger space is used to store coolant, and the heated liquid enters the smaller space and finally flows out through the outlet pipe. A sealing plate, which is installed above the coolant tank; An electric motor is mounted above the sealing plate.

[0007] Furthermore, the auxiliary mechanism also includes: The inlet is located at the bottom of the coolant tank, and the other end of the inlet is connected to the top of the heat dissipation pipe. The return port is located at the bottom of the coolant tank, and the other end of the inlet is connected to the top of the heat dissipation pipe; The scale inhibitor component is installed at the bottom of the motor through the sealing plate. When water is used for cooling, the scale inhibitor component adds a scale inhibitor to soften the water and reduce scale formation.

[0008] Furthermore, the end-face cooling assembly includes: The mounting slot is located inside the housing near one end of the dustproof plate; A driver, wherein the driver is disposed inside the mounting slot; Fan blades, which are mounted at one end of the driver.

[0009] Furthermore, the end-face cooling assembly also includes: The coil is installed at one end of the motor body near the dustproof plate, with one end of the coil extending outwards for connecting to the coolant. A threaded tube is fitted around the outside of the driver and is connected to the inner ring of the coil. The threaded tube is wound around the outside of the driver to cool the driver, so that the driver can work normally and reduce the heat transferred to the motor body again. The liquid outlet is installed at the other end of the threaded pipe.

[0010] Furthermore, the crevice cleaning assembly includes: A telescopic rod, which is installed at the end of the housing away from the dustproof plate; A connecting plate is installed at the other end of the telescopic rod, and each connecting plate is connected to three connecting ropes; A dustproof shell, wherein the dustproof shell is installed at one end of the housing near the connecting plate; A connecting rope, one end of which is connected to the outside of the connecting plate.

[0011] Furthermore, the crevice cleaning assembly also includes: The second scraper is provided, and the connecting rope passes through the second scraper. The second scraper is fixedly connected to the connecting rope. The first scraper is connected to the other end of the connecting rope. The second scraper is positioned close to the first connecting pipe and the second connecting pipe, respectively. Each pair forms a group with the same shape, which is T-shaped, and is slidably connected to the outside of the heat dissipation pipe. The limiting buckle is installed inside the housing, and the connecting rope is sleeved on the outside of the limiting buckle. The limiting buckle is configured with two limiting pieces to place the connecting rope in the middle to prevent the connecting rope from falling off, so that the pulling force of the first scraper and the second scraper is stable and constant.

[0012] Furthermore, the scale inhibition assembly includes: A shaft, which is located below the motor; A connecting rod, wherein the connecting rod is disposed below the shaft; The L-shaped rod is installed below the connecting rod; A stirring blade is mounted above an L-shaped rod.

[0013] Furthermore, the scale inhibition assembly also includes: The storage bin is installed above the connecting rod. The surface of the storage bin has a discharge hole. The storage bin is used to store scale inhibitor. When cooling water enters the coolant tank, the cover plate drives the baffle to rotate, exposing the discharge hole. This allows the scale inhibitor inside the storage bin to come into contact with the water, dissolve, and then the cover plate is closed. This allows for the timely addition of scale inhibitor to prevent scale formation. A cover plate, which is rotatably connected to the top of the storage silo; A baffle is installed below a cover plate, and the outside of the cover plate is slidably connected to the inside of the storage silo.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting up a cooling mechanism, allows the coolant to be cooled comprehensively along the outer surface of the motor body through the passage formed by the first connecting pipe, the second connecting pipe, and the heat dissipation pipe. At the same time, the end-face cooling component allows external air to pass through the casing to cool the motor body and also cool the end face of the motor body. This ensures that the outer surface and one end face of the motor body are cooled comprehensively. Through the combined effect of liquid cooling and air cooling, the motor body is kept at a suitable operating temperature, maintaining the normal operation of the permanent magnet motor.

[0015] 2. This invention, by setting up an auxiliary mechanism, releases scale inhibitors from the scale inhibitor component. After the water and scale inhibitor in the coolant tank are fully mixed, the coolant is then poured into the heat dissipation pipe from the inlet. The water temperature after cooling circulation is relatively high. It returns to the coolant tank and flows out again after being blocked by the heat insulation block. When circulation is required, a longer cooling pipe can be set up externally so that the cooling water is cooled down and returns to the coolant tank. This achieves full-process sealed cooling, reduces external interference, and prevents scale and impurities from clogging the heat dissipation pipe.

[0016] 3. This invention, by setting up a gap cleaning component, allows the connecting rope to drive the second scraper and the first scraper to move along the gap of the heat dissipation pipe. The first scraper moves away from the connecting plate, while the second scraper moves closer to the connecting plate, so that the two scrapers can clean the dust attached to the surface of the heat dissipation pipe. This prevents the dust from accumulating and becoming thicker, which would gradually reduce the heat dissipation effect of the heat dissipation pipe and reduce the combined cooling effect of air cooling and liquid cooling. The active cleaning reduces maintenance costs and makes daily cleaning and periodic deep maintenance very convenient.

[0017] 4. This invention incorporates an end-face cooling assembly. The driver rotates the fan blades, causing external gas to flow into the housing, thus cooling the motor body. The airflow enters through the dust cover and exits through the dust cover. Simultaneously, coolant from the coolant tank is connected to the coil via an external hose and pump, allowing the coolant in the coil to cool the end face of the motor body. The coolant flows from the outer ring to the inner ring and re-enters the threaded tube, also cooling the driver. This prevents the heat generated by the driver during long-term operation from being transferred to the end face of the motor body, thus avoiding excessively high local temperatures in the motor body and affecting the use of the permanent magnet motor.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a permanent magnet motor assembly with a heat dissipation mechanism is described below.

[0022] Including base plate 1, it also includes: The cooling mechanism 2 is set on the base plate 1, the motor body 3 is installed inside the cooling mechanism 2, the auxiliary mechanism 5 is above the cooling mechanism 2, and the liquid outlet pipe 4 is installed outside the auxiliary mechanism 5. During operation, the coolant inside the auxiliary mechanism 5 is pumped into the cooling mechanism 2, so that the cooling mechanism 2 can perform liquid cooling and air cooling on the surface and end face of the motor body 3. Finally, the coolant flows back into the auxiliary mechanism 5 and flows out from the outlet pipe 4. After cooling, it re-enters the auxiliary mechanism 5 for recycling.

[0023] The cooling mechanism 2 includes a housing 201 mounted on the base plate 1, a heat dissipation pipe 205 disposed outside the motor body 3, a gap cleaning component 204 disposed in the gap of the heat dissipation pipe 205, and an end face cooling component 203 mounted on one end of the motor body 3.

[0024] Cooling mechanism 2 also includes: Dustproof plate 202 is installed at one end of housing 201; The first connecting pipe 206 is installed at the end of the heat dissipation pipe 205 away from the dustproof plate 202; The second connecting pipe 207 is installed at one end of the heat dissipation pipe 205 near the dustproof plate 202. The first connecting pipe 206 and the second connecting pipe 207 are staggered on both sides of the heat dissipation pipe 205, so that multiple heat dissipation pipes 205 outside the motor body 3 are connected in an arc shape around the outside of the motor body 3, so that the coolant can cover the circular surface of the motor body 3.

[0025] After the coolant enters the heat dissipation pipe 205, the coolant can be cooled down along the outer surface of the motor body 3 through the passage formed by the first connecting pipe 206, the second connecting pipe 207, and the heat dissipation pipe 205. At the same time, the end face cooling component 203 allows the outside air to pass through the housing 201 to cool the motor body 3 and also cool the end face of the motor body 3. This allows the outer surface and one end face of the motor body 3 to be cooled down. Through the combined effect of liquid cooling and air cooling, the motor body 3 is kept at a suitable operating temperature, ensuring the normal operation of the permanent magnet motor 503.

[0026] Auxiliary mechanism 5 includes: Coolant tank 501 is installed above housing 201; Heat insulation block 502 is installed at the bottom of coolant tank 501. Heat insulation block 502 divides coolant tank 501 into two spaces. The larger space is used to store coolant, and the heated liquid enters the smaller space and finally flows out through the outlet pipe 4. Sealing plate 506 is installed above coolant tank 501; Motor 503 is mounted above sealing plate 506.

[0027] Auxiliary mechanism 5 also includes: The inlet 504 is located at the bottom of the coolant tank 501, and the other end of the inlet 504 is connected to the top of the heat dissipation pipe 205. The return port 505 is located at the bottom of the coolant tank 501, and the other end of the inlet 504 is connected to the top of the heat pipe 205. The scale inhibitor component 507 is installed at the bottom of the motor 503 through the sealing plate 506. When water is used for cooling, the scale inhibitor component 507 adds scale inhibitor to soften the water and reduce scale formation.

[0028] When using water as the coolant, a scale inhibitor needs to be added for pretreatment to reduce scale formation. Scale is then stored inside the scale inhibitor component 507. When the coolant enters the coolant tank 501, the scale inhibitor component 507 releases the scale inhibitor, thoroughly mixing the water and the scale inhibitor in the coolant tank 501. Then, the coolant is poured into the radiator pipe 205 from the inlet 504. The water temperature after cooling circulation is high, and it returns to the coolant tank 501, where it is blocked by the heat insulation block 502 before flowing out again. When recirculation is required, a longer cooling pipe can be installed externally to allow the coolant to cool down and return to the coolant tank 501, achieving fully sealed cooling and reducing external interference that could cause scale and other impurities to clog the radiator pipe 205.

[0029] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the end face cooling assembly 203 includes: Mounting slot 2031 is located inside the housing 201 at one end near the dustproof plate 202; Driver 2032 is disposed inside mounting slot 2031; Fan blade 2033 is mounted on one end of driver 2032.

[0030] The end-face cooling assembly 203 also includes: Coil 2034 is installed at one end of the motor body 3 near the dustproof plate 202. One end of the coil 2034 protrudes outward for connecting to the coolant. The threaded tube 2035 is sleeved on the outside of the driver 2032. The threaded tube 2035 is connected to the inner ring of the coil 2034. The threaded tube 2035 is wound around the outside of the driver 2032 to cool the driver 2032, so that the driver 2032 can work normally and reduce the temperature from being transferred to the motor body 3 again. The liquid outlet 2036 is installed at the other end of the threaded pipe 2035.

[0031] During use, the driver 2032 drives the fan blades 2033 to rotate, causing the external air to flow into the housing 201, thus cooling the motor body 3. The airflow enters through the dustproof plate 202 and exits through the dustproof shell 2043. At the same time, the coolant in the coolant tank 501 is connected to the coil 2034 through the external hose and pump body, so that the coolant in the coil 2034 cools the end face of the motor body 3. The coolant flows from the outer ring to the inner ring and re-enters the threaded tube 2035, which also cools the driver 2032. This prevents the heat generated by the driver 2032 during long-term operation from being transferred to the end face of the motor body 3, which would cause the local temperature of the motor body 3 to be too high and affect the use of the permanent magnet motor 503.

[0032] Crevice cleaning component 204 includes: Telescopic rod 2041 is installed at the end of housing 201 away from dustproof plate 202; A connecting plate 2042 is installed at the other end of the telescopic rod 2041, and each connecting plate 2042 is connected to three connecting ropes 2044; Dustproof shell 2043 is installed at one end of housing 201 near connecting plate 2042. Dustproof shell 2043 and dustproof plate 202 are respectively set at both ends of housing 201 to reduce dust from entering the interior of housing 201. The connecting rope 2044 has one end connected to the outside of the connecting plate 2042. The connecting rope 2044 is divided into two sections. One section is from the connecting plate 2042 to the second scraper 2046. This section is a rigid rod. The section between the first scraper 2045 and the second scraper 2046 is made of a deformable rope-like material.

[0033] Crevice cleaning component 204 also includes: The second scraper 2046 is provided with a connecting rope 2044 passing through it, and the second scraper 2046 is fixedly connected to the connecting rope 2044. The first scraper 2045 is connected to the other end of the connecting rope 2044. The second scraper 2046 is positioned close to the first connecting pipe 206 and the second connecting pipe 207 respectively. Each pair forms a group, and they have the same shape, which is T-shaped. They are slidably connected to the outside of the heat dissipation pipe 205. The limit buckle 2047 is installed inside the housing 201, and the connecting rope 2044 is sleeved on the outside of the limit buckle 2047. The limit buckle 2047 is configured with two limit plates to place the connecting rope 2044 in the middle to prevent the connecting rope 2044 from falling off, so that the pulling force of the first scraper 2045 and the second scraper 2046 is stable and constant.

[0034] In use, the telescopic rod 2041 drives the connecting plate 2042 to pull the connecting rope 2044 outward, causing the connecting rope 2044 to drive the second scraper 2046 and the first scraper 2045 to move along the gap of the heat dissipation pipe 205. The first scraper 2045 moves away from the connecting plate 2042, while the second scraper 2046 moves closer to the connecting plate 2042, so that the two scrapers can clean the dust attached to the surface of the heat dissipation pipe 205, preventing the dust from accumulating and causing the heat dissipation effect of the heat dissipation pipe 205 to gradually deteriorate, thus reducing the combined cooling effect of air cooling and liquid cooling. Active cleaning reduces maintenance costs and makes daily cleaning and periodic deep maintenance very convenient.

[0035] Scale inhibitor assembly 507 includes: Shaft 5071 is located below motor 503; Connecting rod 5072 is located below shaft 5071; L-shaped rod 5073, L-shaped rod 5073 is installed below connecting rod 5072; Agitator blade 5074 is mounted above L-shaped rod 5073.

[0036] Scale inhibitor assembly 507 also includes: Storage bin 5075 is installed above connecting rod 5072. Storage bin 5075 has a discharge hole 5076 on its surface. Storage bin 5075 is used to store scale inhibitor. When cooling water enters coolant tank 501, cover plate 5077 drives baffle 5078 to rotate, exposing discharge hole 5076, so that scale inhibitor inside storage bin 5075 comes into contact with water, dissolves, and then cover plate 5077 is closed, so as to realize the timely addition of scale inhibitor to prevent scale formation. Cover plate 5077 is rotatably connected above storage bin 5075; Baffle 5078 is installed below cover 5077, and the outside of cover 5077 is slidably connected to the inside of storage bin 5075.

[0037] Before operation, the scale inhibitor is placed in the storage silo 5075, and coolant is added to the storage silo 5075. When the liquid level reaches a certain height (the storage silo 5075 is immersed in water), the cover plate 5077 is rotated, causing the baffle 5078 to be misaligned with the discharge hole 5076, allowing the cooling water to come into contact with the scale inhibitor and dissolve it in the water. The motor 503 drives the connecting rod 5072 under the rotating rod to rotate, causing the stirring liquid to fully mix the scale inhibitor and water. The dissolved content of the scale inhibitor is judged according to the time. When new cooling water is added again, the storage silo 5075 is opened again to replenish the scale inhibitor, reducing the amount of manual processing. The cooling water can automatically mix and replenish with the scale inhibitor, preventing the formation of scale, thereby further reducing the possibility of scale clogging the heat dissipation pipe 205 and extending the service life of the permanent magnet motor 503.

[0038] The specific workflow is as follows: When using water as coolant, scale inhibitors need to be added for pretreatment to reduce scale formation. Scale is then stored inside the scale inhibitor component 507. When coolant enters the coolant tank 501, the scale inhibitor component 507 releases the scale inhibitor, thoroughly mixing the water and scale inhibitor in the coolant tank 501. Then, the coolant is poured into the radiator pipe 205 from the inlet 504. The water temperature after cooling circulation is high, and it returns to the coolant tank 501, where it is blocked by the heat insulation block 502 before flowing out again. When circulation is required, a longer cooling pipe can be installed externally to allow the coolant to cool down and return to the coolant tank 501, achieving fully sealed cooling and reducing external interference that could cause scale and impurities to clog the radiator pipe 205. After the coolant enters the heat dissipation pipe 205, the coolant can be cooled down along the outer surface of the motor body 3 through the passage formed by the first connecting pipe 206, the second connecting pipe 207, and the heat dissipation pipe 205. At the same time, the end face cooling component 203 allows the outside air to pass through the housing 201 to cool the motor body 3 and also cool the end face of the motor body 3. This allows the outer surface and one end face of the motor body 3 to be cooled down. Through the combined effect of liquid cooling and air cooling, the motor body 3 is kept at a suitable operating temperature, ensuring the normal operation of the permanent magnet motor 503.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
