Description

Technical Field

[0001] This utility model relates to a cooling cover for a permanent magnet motor, belonging to the technical field of cooling cover technology. Background Technology

[0002] Motors generate heat during operation. If this heat cannot be dissipated quickly, it can lead to damage to internal components due to overheating, affecting normal operation and consequently impacting motor performance and lifespan. Therefore, a cooling enclosure is needed to ensure heat dissipation during operation.

[0003] However, the existing cooling covers of permanent magnet motors all adopt a heat dissipation cooling method with air intake on one side or one end, which cannot form effective gas convection for heat dissipation. They cannot quickly and effectively remove the heat generated by long-term operation, resulting in unsatisfactory heat dissipation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a permanent magnet motor cooling cover that can achieve convection cooling and efficient heat dissipation.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0012] Furthermore, a second filter screen is installed at the edge of the outer opening of the second protective shell, and the second filter screen is fixed to the second protective shell.

[0013] Furthermore, the front cover is fixedly installed on the main convection cooling cover, and the rear cover is fixedly installed on the main convection cooling cover. Both the first protective cover and the second protective cover are provided with supporting and fixing legs on their lower bottom surfaces.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The cooling casing of the permanent magnet motor in this application achieves air circulation within the device through the cooperation of the shell, convection groove, ventilation grille, first protective shell, second protective shell, intake fan, and exhaust fan in the main casing for convection cooling.

[0022] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-5 As shown, the cooling cover of the permanent magnet motor provided in this embodiment includes a permanent magnet motor body 1, a convection cooling main cover 2 sleeved on the outside of the permanent magnet motor body 1, a front cover 3 installed at one end opening of the convection cooling main cover 2, and a rear cover 4 installed at the other end opening of the convection cooling main cover 2; the convection cooling main cover 2 includes a shell 5, a plurality of convection grooves 6 opened on the inner wall of the shell 5, ventilation grilles 7 symmetrically opened on both sides of the shell 5, a first protective shell 8 disposed on the surface of one ventilation grille 7, a second protective shell 9 disposed on the surface of the other ventilation grille 7, a plurality of intake fans 10 installed in the first protective shell 8, and a plurality of exhaust fans 11 installed in the second protective shell 9. The convection cooling main casing 2, front casing 3, and rear casing 4 are used to securely enclose and protect the permanent magnet motor body 1. Simultaneously, the convection cooling main casing 2 circulates internal and external airflow to cool the permanent magnet motor body 1 during operation, preventing excessive heat generation due to prolonged rotation and ensuring its normal operation. The convection channel 6 allows airflow within the housing 5 to carry away the heat generated by the permanent magnet motor body 1. The ventilation grille 7 facilitates rapid convection between the outside and inside the housing 5. The first protective casing 8 supports and protects the intake fan 10. The second protective casing 9 supports and protects the exhaust fan 11. The intake fan 10 draws in cool outside air into the housing 5, while the exhaust fan 11 expels air from the housing 5 to the outside. The intake fan 10 and exhaust fan 11 achieve internal and external airflow circulation, thus achieving a cooling effect.

[0024] Furthermore, such as Figures 1-3As shown, the intake fan 10 includes a first support connecting rod 12, a forward rotation motor 13 embedded in the first support connecting rod 12, and a first rotating blade 14 installed at the output end of the forward rotation motor 13. The first support connecting rod 12 is used to support and fix the forward rotation motor 13, and at the same time, it is used to fix the intake fan 10 between the upper and lower inner walls of the first protective shell 8. The forward rotation motor 13 is used to provide forward rotation driving force for the first rotating blade 14. The first rotating blade 14 will draw cold air from the outside into the shell 5 under the drive of the forward rotation motor 13.

[0025] Furthermore, such as Figures 1-3 As shown, the first support connecting rod 12 is fixed to the inner wall of the first protective shell 8 by bolts, which facilitates the replacement or maintenance of the intake fan 10. The first rotating blade 14 is fixed to the output end of the forward rotating motor 13 by bolts, which facilitates the replacement or maintenance of the first rotating blade 14.

[0026] Furthermore, such as Figures 1-3 As shown, the exhaust fan 11 includes a second support connecting rod 15, a reverse motor 16 embedded in the second support connecting rod 15, and a second rotating blade 17 installed at the output end of the reverse motor 16. The second support connecting rod 15 is used to support and fix the reverse motor 16, and at the same time, it is used to fix the exhaust fan 11 between the upper and lower inner walls of the second protective shell 9. The reverse motor 16 is used to provide reverse driving force for the second rotating blade 17. The second rotating blade 17 will exhaust the hot air in the shell 5 to the outside under the drive of the reverse motor 16.

[0027] Furthermore, such as Figures 1-3 As shown, the second support connecting rod 15 is fixed to the inner wall of the second protective shell 9 by bolts, which facilitates the replacement or maintenance of the exhaust fan 11. The second rotating blade 17 is fixed to the output end of the reverse motor 16 by bolts, which facilitates the replacement or maintenance of the second rotating blade 17.

[0028] Furthermore, such as Figure 1 As shown, a first filter screen 18 is installed at the edge of the opening on the outer side of the first protective shell 8. The first filter screen 18 is fixed to the first protective shell 8 by bolts, which facilitates the replacement or cleaning of the first filter screen 18. The first filter screen 18 can prevent foreign objects from entering the shell 5.

[0029] Furthermore, such as Figure 1 As shown, a second filter screen 19 is installed at the edge of the opening on the outer side of the second protective shell 9. The second filter screen 19 is fixed to the second protective shell 9 by bolts, which facilitates the replacement or cleaning of the second filter screen 19. The second filter screen 19 can prevent foreign objects from entering the shell 5.

[0030] Furthermore, such as Figure 1 , Figure 4as well as Figure 5 As shown, the front cover 3 is fixedly installed on the convection cooling main cover 2 by bolts, and the rear cover 4 is fixedly installed on the convection cooling main cover 2 by bolts, so that after the permanent magnet motor body 1 is placed into the convection cooling main cover 2, the two ends of the opening of the convection cooling main cover 2 can be locked and fixed. The bottom surfaces of the first protective shell 8 and the second protective shell 9 are provided with supporting and fixing legs 20, which play a supporting and fixing role.

[0031] like Figures 1-5 As shown, the principle of the cooling cover of the permanent magnet motor provided in this embodiment is as follows: When using the cover, first fix the rear cover 4 to the rear opening of the convection cooling main cover 2 with bolts, put the permanent magnet motor body 1 into the convection cooling main cover 2, fix the front cover 3 to the front opening of the convection cooling main cover 2 with bolts, and ensure that the permanent magnet motor body 1 is locked and fixed so that it will not shake during operation. Then fix the intake fan 10 between the upper and lower inner walls of the first protective cover 8 with bolts. After that, fix the first filter screen 18 to the outer opening of the first protective cover 8 with bolts. Fix the exhaust fan 11 between the upper and lower inner walls of the second protective cover 9 with bolts. Fix the second filter screen 19 to the outer opening of the second protective cover 9 with bolts.

[0032] When the permanent magnet motor body 1 generates too much heat due to long-term operation, the intake fan 10 starts to run rapidly. The rapid rotation of the first rotating blade 14 causes the cold air from the outside to quickly pass through the first filter screen 18 and the ventilation grille 7 and flow into the housing 5. At the same time, the exhaust fan 11 also runs rapidly. The rapid rotation of the second rotating blade 17 causes the hot air in the housing 5 to quickly pass through the second filter screen 19 and the ventilation grille 7 and be discharged to the outside.

[0033] The intake fan 10 and the exhaust fan 11 work together to enable rapid convection between the airflow inside the housing 5 and the airflow outside. The airflow will flow rapidly in the convection grooves 6 opened on the inner wall of the housing 5. The rapidly flowing airflow can carry away the heat on the surface of the permanent magnet motor body 1. Since the intake fan 10 and the exhaust fan 11 will work continuously, the airflow will always be in a state of rapid convection, thereby achieving rapid cooling of the permanent magnet motor body 1.

[0034] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
