Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of generators, and in particular relates to a generator with good heat dissipation performance. Background Art
[0002] In the prior art, the heat dissipation of the generator mainly relies on natural convection or simple air cooling, such as setting heat sinks on the motor housing to increase the surface area to promote air cooling, or using the airflow generated by the motor's own operation for passive heat dissipation. However, these methods have limitations in heat dissipation efficiency, especially in closed or confined spaces, and in high-power density design scenarios. The heat dissipation effect is often unsatisfactory and it is difficult to meet the needs of efficient and continuous operation. In addition, the lack of effective airflow guidance and acceleration mechanisms makes heat accumulation common, increases the risk of overheating, and affects the stability and safety of the generator.
[0003] In summary, the existing heat dissipation solutions for generators have obvious deficiencies in heat dissipation efficiency, system stability and safety, which limits the development potential of generators in high-performance application fields. Therefore, it is urgent to develop a generator with good heat dissipation performance, which can effectively improve heat exchange efficiency and ensure long-term stable operation. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the utility model provides a generator with good heat dissipation performance, which significantly improves the heat dissipation effect and reduces the failure rate by adding a heat dissipation shell, a heat dissipation fan and adopting an innovative airflow control design.
[0005] In order to solve the above technical problems, the utility model solves them through the following technical solutions.
[0006] A generator with good heat dissipation performance comprises a motor housing, a rotating shaft is installed in the motor housing, two ends of the rotating shaft extend from the motor housing, the front end of the rotating shaft is an output end, and the rear end of the rotating shaft is equipped with a heat dissipation fan. A heat dissipation shell is sleeved on the motor housing, and a heat dissipation channel for guiding air to flow in the axial direction is arranged on the heat dissipation shell. By adding a heat dissipation shell and a heat dissipation fan, this design improves the heat dissipation efficiency of the generator, reduces the failure rate caused by overheating, and ensures the long-term stable and safe operation of the equipment.
[0007] Preferably, the axial flow cross section of the heat dissipation channel gradually decreases from the front end of the rotating shaft to the rear end of the rotating shaft. This design utilizes the Venturi effect, and under the action of the heat dissipation fan, it can accelerate the speed of air flowing through the heat dissipation channel, thereby greatly improving the heat exchange efficiency.
[0008] Preferably, a protective cover is mounted on the end surface of the motor housing to cover the cooling fan inside, and a circular collector is arranged on the side of the protective cover, and the collector is used to guide the air from the cooling channel to the cooling fan. A plurality of through grooves are arranged on the side of the protective cover, and the through grooves are located at the position where the cooling fan is close to the motor housing. This design realizes effective protection of the cooling fan and air diversion through the protective cover and the collector.
[0009] Preferably, the motor housing is provided with a plurality of arc-shaped limiting slide grooves, and the protective cover is provided with a plurality of limiting heads corresponding to the limiting slide grooves. This limiting design simplifies the assembly steps.
[0010] Compared with the prior art, the present application has the following beneficial effects: by adding a heat dissipation shell and a heat dissipation fan, the heat dissipation efficiency of the generator is improved, the failure rate caused by overheating is reduced, and the long-term stable and safe operation of the equipment is ensured.

[0023] Reference Figures 1 to 5 A generator with good heat dissipation performance includes a motor housing 100, a rotating shaft 110 is installed in the motor housing 100, both ends of the rotating shaft 110 extend from the motor housing 100, the front end of the rotating shaft 110 is an output end, and the rear end of the rotating shaft 110 is equipped with a heat dissipation fan 120. The motor housing 100 is covered with a heat dissipation shell 200, and the heat dissipation shell 200 is provided with a heat dissipation channel 210 for guiding air to flow in the axial direction. By adding the heat dissipation shell 200 and the heat dissipation fan 120, the heat dissipation efficiency of the generator is improved, the failure rate caused by overheating is reduced, and the long-term stable and safe operation of the equipment is ensured.
[0024] Specifically, the axial flow cross-section of the heat dissipation channel 210 gradually decreases from the front end of the rotating shaft 110 to the rear end of the rotating shaft 110. It not only promotes the natural increase of air flow rate, but also utilizes the principle of airflow acceleration, greatly enhancing the cooling efficiency during the heat exchange process. The distance from the axis of the heat dissipation channel 210 to the axis of the rotating shaft 110 gradually decreases from the front end of the rotating shaft 110 to the rear end of the rotating shaft 110. At the same time, it helps to effectively converge the airflow before it enters the cooling fan 120. This design can take away heat faster, reduce the risk of performance degradation or damage to electronic components or mechanical equipment due to overheating, and can also reduce the demand for the power of the cooling fan 120, thereby improving the overall energy efficiency and operating stability of the equipment.
[0025] Furthermore, a protective cover 300 is mounted on the end surface of the motor housing 100 to cover the cooling fan 120 inside. A circular manifold 310 is arranged on the side of the protective cover 300. The manifold 310 is used to guide the air from the cooling channel 210 to the cooling fan 120. A plurality of through grooves 320 are arranged on the side of the protective cover 300. The through grooves 320 are located at the position where the cooling fan 120 is close to the motor housing 100. This design realizes effective protection of the cooling fan 120 and air guidance through the protective cover 300 and the manifold 310. The design of the manifold 310 ensures that the air introduced from the cooling channel 210 can flow smoothly and centrally to the cooling fan 120, thereby enhancing the cooling efficiency of the fan.
[0026] To facilitate the assembly of the protective cover 300, the motor housing 100 is provided with a plurality of arc-shaped limiting slots 130, and the protective cover 300 is provided with a plurality of limiting heads 330 corresponding to the limiting slots 130. The protective cover 300 can be fixed to the motor housing 100 by inserting the limiting heads 330 into the limiting slots 130 and rotating the protective cover 300 at a certain angle. The fixing is completed by rotating the protective cover 300, which is convenient and space-saving, and is also convenient for later maintenance and disassembly, thereby improving the ease of use of the overall design.
[0027] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
