Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor technology, specifically a permanent magnet motor with a long lifespan. Background Technology

[0002] A permanent magnet motor is a type of motor that uses the magnetic field generated by a permanent magnet to drive the motor's rotation. Its working principle is based on Faraday's law of electromagnetic induction and the Lorentz force principle. When current flows through the coil of the permanent magnet motor, a magnetic field is generated around the coil. This magnetic field interacts with the permanent magnet, causing it to experience a torque, thus inducing rotation. The direction of the current in the coil and the direction of the magnetic field of the permanent magnet determine the direction of the torque acting on the permanent magnet, thereby causing the motor to rotate.

[0003] Traditional motor cooling often employs a combination of heat-conducting fins and a cooling fan. However, this method has significant drawbacks: the heat-conducting fins diffuse heat throughout the motor, resulting in the cooling fan drawing in hot air. This significantly reduces cooling efficiency, especially in hot weather, where the cooling effect is almost nonexistent. The direct consequence is a high motor failure rate and a significantly shortened service life. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

At the same time, the airflow generated by the cooling fan in the rear shell acts on the inside of the body shell and is diverted into multiple air ducts. The air ducts maintain the low temperature of the condensate around them, ensuring the heat exchange effect. This dual cooling mechanism of condensate and airflow significantly improves the environment around the motor, keeps cool air entering the rear shell, reduces the motor failure rate, and ensures its service life.

[0011] In a preferred embodiment, this utility model can be further configured such that multiple heat dissipation fins are grouped in pairs, with each pair of two heat dissipation fins forming a clamping space suitable for the installation of the heat exchange tube body.

[0012] In a preferred embodiment, the present invention can be further configured such that: a recycling mechanism is provided on the front side of the front end shell, the recycling mechanism including a collection box fixedly connected to the front side of the front end shell, a cover fastened to the top of the condensate box, and a micro pump connected between the collection box and the cover.

[0013] In a preferred embodiment, the present invention can be further configured such that a filter plate is embedded on the rear side of the rear end shell, and the thickness of the filter plate is equal to the wall thickness of the rear end shell.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] In this invention, condensate in the condensate box is injected into two diversion channels and then fills multiple heat exchange tubes.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a long-life permanent magnet motor. Example

[0030] Combination Figure 1-6 As shown, the present invention provides a long-life permanent magnet motor, including a protection mechanism 100 and a cooling mechanism 200. The protection mechanism 100 includes a body shell 110, a front shell 120 connected to the front end of the body shell 110, and a rear shell 130 connected to the rear end of the body shell 110.

[0031] The cooling mechanism 200 includes a condensate box 210 embedded in the top of the outer shell 110, two diversion channels 220 connected and communicating with the condensate box 210, a plurality of heat exchange tubes 230 installed on the front side of the diversion channels 220 and communicating with the interior of the diversion channels 220, a plurality of heat dissipation fins 240 connected to the outer shell 110, and an air duct 250 connecting the diversion channels 220 and the heat exchange tubes 230.

[0032] Furthermore, two diversion channels 220 are located on both sides of the condensate box 210. The inner side of the diversion channel 220 is fixed to the outer wall of the outer shell 110. The layout design of the diversion channel 220 indirectly guides the layout of the heat exchange tube 230, enabling the heat exchange tube 230 to uniformly cool the outer shell 110.

[0033] Furthermore, multiple arc grooves are provided on both sides of the outer shell 110, and the outer walls of multiple heat exchange tubes 230 are respectively fixed to the inner walls of multiple arc grooves. By setting the arc grooves, the heat conduction effect at the local position of the outer shell 110 is improved after the wall thickness is reduced, and the material used in manufacturing the outer shell 110 is also reduced, thereby reducing the manufacturing cost to a certain extent.

[0034] Furthermore, the heat exchange tube 230 is bent at the front end, and both the front end of the heat exchange tube 230 and the front end of the air duct 250 penetrate the front side of the front shell 120. The rear end of the air duct 250 extends into the interior of the rear shell 130. The installation design of the heat exchange tube 230 can strengthen the connection between the front shell 120 and the outer shell 110. Then, the air duct 250 can divert a portion of the cool air inside the rear shell 130. After this cool air is directed to the outside of the outer shell 110, it can improve the environment of the outer shell 110 and, to a certain extent, assist the fan inside the rear shell 130 in obtaining cool air.

[0035] Furthermore, multiple heat dissipation fins 240 are arranged in pairs, forming multiple groups. The two heat dissipation fins 240 in each group form a clamping space suitable for the installation of the heat exchange tube 230. The layout design of the heat dissipation fins 240 can effectively conduct away their own heat. Example

[0036] Combination Figure 1 , 2 and Figure 6 As shown, based on Embodiment 1, a recycling mechanism 300 is provided on the front side of the front shell 120. The recycling mechanism 300 includes a collection box 310 fixed to the front side of the front shell 120, a cover 320 fastened to the top of the condensate box 210, and a micro pump 330 connected between the collection box 310 and the cover 320. The collection box 310 and the micro pump 330 cooperate to facilitate the return of the condensate flowing out of the heat exchange tube 230 and improve resource utilization. Example

[0037] Combination Figure 2-3 As shown, in the above embodiment, a filter plate 400 is embedded on the rear side of the rear end shell 130. The thickness of the filter plate 400 is equal to the wall thickness of the rear end shell 130. The filter plate 400 can filter the air entering the rear end shell 130 and improve the safety of the operation of the components inside the body shell 110.

[0038] The working principle and usage process of this utility model are as follows: In the initial state, the outer shell 110, the front shell 120, and the rear shell 130 are used in conjunction with a permanent magnet motor. When the device is put into actual use, the condensate in the condensate box 210 is injected into two diversion channels 220, and then fills multiple heat exchange tubes 230. The condensate indirectly carries away the heat from the heat dissipation fins 240 by lowering the temperature of the tube walls of the heat exchange tubes 230, thereby reducing the overall temperature of the multiple heat dissipation fins 240. At the same time, the airflow generated by the cooling fan in the rear shell 130 acts on the inside of the outer shell 110 and is diverted into multiple air ducts 250. The air ducts 250 maintain the low temperature of the condensate around them to ensure the heat exchange effect. Afterward, the airflow blows to the front side of the front shell 120 to cool the environment around the motor. Through this dual cooling mechanism of condensate and airflow, the heat dissipation effect is significantly improved, the motor failure rate is reduced, and its service life is guaranteed.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
