Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor technology, specifically to a high-efficiency cooling end cover structure for permanent magnet motors. Background Technology

[0002] A permanent magnet motor consists of components such as a stator, rotor, and end covers. The stator is basically the same as that of a conventional induction motor, but it uses a laminated structure to reduce iron losses during operation. The rotor can be made solid or made of laminated laminations. The armature winding can be a concentrated full-pitch winding, a distributed short-pitch winding, or an unconventional winding.

[0003] Currently, the end caps of most commonly used permanent magnet motors have relatively simple structures and poor heat dissipation performance. After working for a long time, they generate a lot of heat, which can affect the normal operation of some internal parts of the permanent magnet motor and thus affect the normal operation of the permanent magnet synchronous motor. To address this issue, we propose a high-efficiency cooling end cap structure for permanent magnet motors. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency cooling end cover structure for permanent magnet motors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cooling end cover structure for a permanent magnet motor, including a permanent magnet motor body. Several side holes are opened on the side of the right end cover of the permanent magnet motor body. Heat dissipation fins are vertically arranged between two adjacent side holes, and an independent air duct is formed between two adjacent heat dissipation fins. A fan is provided on the top of the right end cover of the permanent magnet motor body, and multiple fan-shaped holes are opened on the right side. A ventilation volume adjustment component is provided on the right side of the fan-shaped holes.

[0006] In a further preferred embodiment, the ventilation volume adjustment component includes a pin fixedly connected to the right side of the end cover of the permanent magnet motor body, and a round block is rotatably connected to the outside of the pin.

[0007] More preferably, a plurality of sector plates are fixedly connected to the outer side of the circular block, and a circular ring is fixedly connected to the outer side of the sector plates.

[0008] More preferably, there is a gap between two adjacent sector plates, forming multiple sector-shaped gaps.

[0009] More preferably, two heat-conducting plates are fixedly connected to the right side of the permanent magnet motor body, and a heat-conducting rail is fixedly connected between the two heat-conducting plates. The heat-conducting rail is arc-shaped, and a sliding plate is slidably connected to the outer side of the heat-conducting rail. The sliding plate is fixedly connected to a ring.

[0010] More preferably, a thermal spring is fixedly connected between the slide plate and the heat-conducting plate, and the thermal spring is movably sleeved on the outside of the heat-conducting guide rail.

[0011] More preferably, the fan has a housing on its outer side, the housing is fixedly connected to the top of the permanent magnet motor body, and a dust filter is provided on the top of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When this utility model is used, the vertical arrangement of the heat dissipation fins creates an independent airflow channel between two adjacent heat dissipation fins. When the fan rotates, the airflow flows upward, and the heat exchange speed is accelerated by multiple independent airflow channels. When the heat dissipation of the permanent magnet motor body continues to increase, the heat is conducted to the two heat-conducting plates. The thermal spring is heated and undergoes tensile deformation, which drives the sliding plate to slide backward and rotate on the outside of the heat-conducting rail. The rotation of the ring causes the overlapping area of ​​the fan-shaped plate and the fan-shaped hole to decrease, and the overlapping area of ​​the fan-shaped gap and the fan-shaped hole to increase, thereby increasing the gap of the hole and increasing the air intake, further improving the heat exchange effect.

A ventilation volume adjustment component is arranged to the right of the fan-shaped holes 5. In use, the vertical arrangement of the heat dissipation fins 3 ensures that an independent air duct is formed between adjacent heat dissipation fins 3. In the vertical air duct, when the fan 4 rotates, the airflow flows upward. With the acceleration of multiple independent air ducts, the heat exchange speed is accelerated. When the heat dissipation of the permanent magnet motor body 1 continues to increase, the heat is conducted to the two heat-conducting plates 11. The thermal spring 14 is heated and undergoes tensile deformation, which drives the slide plate 13 to slide backward and rotate on the outside of the heat-conducting rail 12. The rotation of the ring 9 causes the overlapping area of ​​the fan-shaped plate 8 and the fan-shaped hole 5 to decrease, and the overlapping area of ​​the fan-shaped gap 10 and the fan-shaped hole 5 to increase, thereby increasing the gap of the hole, thereby increasing the air intake and further improving the heat exchange effect.

[0018] In operation, the heat dissipation fins 3 are vertically arranged, forming independent air ducts between adjacent heat dissipation fins 3. When the fan 4 rotates, the airflow flows upward, and the heat exchange speed is accelerated by multiple independent air ducts. When the heat dissipation of the permanent magnet motor body 1 continues to increase, the heat is conducted to the two heat-conducting plates 11. The thermal spring 14 is heated and undergoes tensile deformation, which drives the slide plate 13 to slide backward and rotate on the outside of the heat-conducting rail 12. The rotation of the ring 9 causes the overlapping area of ​​the fan-shaped plate 8 and the fan-shaped hole 5 to decrease, and the overlapping area of ​​the fan-shaped gap 10 and the fan-shaped hole 5 to increase, thereby increasing the gap of the hole, thereby increasing the air intake and further improving the heat exchange effect.
