Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a rotor disk with efficient heat dissipation function. Background Technology

[0002] As a key component of core components such as motors, the rotor disc's performance and heat dissipation efficiency directly affect the stability and service life of the entire equipment.

[0003] Existing rotor disc structures generally suffer from insufficient heat dissipation design: on the one hand, traditional rotor discs are mostly solid or have simple groove structures, lacking dedicated heat dissipation channels, making it difficult to quickly dissipate the heat generated during operation, which easily leads to heat accumulation. Especially when running at high speed, the temperature rises significantly, which may affect the motor's operating accuracy and stability. On the other hand, the housing structure used to load the magnets is usually highly sealed, and the heat generated by the magnets during operation cannot be effectively dissipated. Long-term high-temperature environment can easily lead to the decay of the magnets' magnetic properties and shorten their service life.

[0004] Meanwhile, the end face design of existing rotor disks is mostly a smooth plane or a simple straight groove structure, which results in poor air flow and low heat dissipation efficiency during rotation; in addition, some rotor disks do not have dedicated heat-conducting components or the heat-conducting materials have poor performance, which makes it impossible for the heat inside the disk to be quickly transferred to the outside for heat dissipation.

[0005] In addition, the covers on both sides of the existing rotor disk mostly adopt a flat or simple raised structure. When used with fan cooling or rotating on its own, the air resistance is large, which not only increases the energy consumption of the motor, but also affects the stability of the heat dissipation effect due to airflow disturbance. Utility Model Content

[0006] The present invention aims to solve the above-mentioned defects and provide a rotor disk with efficient heat dissipation function.

[0007] In order to overcome the defects in the background technology, the technical solution adopted by this utility model to solve its technical problem is: a rotor disk with efficient heat dissipation function, including a disk body, the two end faces of which are recessed inward to form an inner groove, the bottom surface of the inner groove is provided with reinforcing ribs arranged radially, and the bottom surface of the inner groove is provided with multiple receiving cavities for loading magnets in the circumferential direction with the central axis of the disk body as the center, and multiple spiral grooves are provided on its outer circumferential surface in a spiral distribution, and heat-conducting strips are loaded in the fine holes opened along the radial direction of the disk body on its outer circumferential surface.

[0008] The cover is detachably installed in the inner grooves on both sides of the disk body, thereby securing the magnet within the receiving cavity. The end face of the cover away from the disk body is set as a smooth, raised curved surface.

[0009] Further improvements include using graphene material for the heat-conducting strip.

[0010] A further improvement includes that the magnet comprises multiple sheets, and an insulating material is disposed between adjacent sheets.

[0011] Further improvements include the provision of multiple micro-heat dissipation holes on the inner wall of the receiving cavity, with the channels of the micro-heat dissipation holes extending radially to the outer circumferential surface of the disk.

[0012] The beneficial effects of this utility model are as follows: In this design, the spiral groove and the heat-conducting strip work together to improve heat dissipation efficiency, and the heat-conducting strip made of graphene material can conduct heat quickly; the micro heat dissipation holes in the cavity are for magnetic steel heat dissipation, avoiding magnetic performance attenuation; the reinforcing ribs can help disperse heat while strengthening the overall structural strength of the disc; the curved surface design of the cover reduces wind resistance and energy consumption; the insulating material between the sheets reduces eddy current loss.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0022] refer to Figure 1 , Figure 2 and Figure 3 A rotor disk with high-efficiency heat dissipation function includes a disk body 1, with its two end faces recessed inward to form an inner groove 3. The bottom surface of the inner groove 3 is provided with radially distributed reinforcing ribs 2, which not only enhances the structural stability but also increases the heat dissipation area to assist heat dissipation. The bottom surface of the inner groove 3 is provided with multiple receiving cavities 4 for loading magnets 6 in a circumferential direction with the central axis of the disk body 1 as the center. Multiple spiral grooves 5 are provided on its outer circumferential surface, which can accelerate heat dissipation by allowing airflow. Furthermore, heat-conducting strips 7 are loaded in the fine holes opened along the radial direction of the disk body 1 on its outer circumferential surface, which further improves the heat conduction efficiency and enhances the heat dissipation effect.

[0023] The cover 8 is respectively embedded in the inner grooves 3 on both sides of the disk 1, thereby securing the magnet 6 within the receiving cavity 4. The end face of the cover 8 away from the disk 1 is set as a smooth raised curved surface. This structure can effectively reduce the air resistance when the fan cools the rotor disk and when the rotor disk rotates, reduce the wind resistance loss during motor operation, and thus improve the motor's working efficiency.

[0024] In this design, the spiral groove 5 can accelerate the dissipation of heat by utilizing the airflow generated when the rotor rotates; the heat-conducting strip 7 can quickly conduct the heat inside the disk 1 to the heat dissipation channel. The two work together to effectively improve the overall heat dissipation efficiency.

[0025] In a specific embodiment, the heat-conducting strip 7 is made of graphene material. The heat-conducting strip 7 made of this material can quickly conduct the heat inside the disk 1 to the heat dissipation channel, significantly improving the heat dissipation efficiency and reducing the working temperature of the rotor disk to 15-20°C.

[0026] For specific embodiments, please refer to Figure 4 and Figure 5 The magnet 6 includes multiple sheets 602, and an insulating material 601 is provided between adjacent sheets 602. The insulating material 601 forms a physical isolation between the sheets 602, which can effectively block the path of eddy current formation, thereby greatly reducing eddy current loss.

[0027] In a specific embodiment, the inner wall of the receiving cavity 4 is provided with multiple micro heat dissipation holes, each with a diameter of 0.8-1.2 mm, and the channels of the micro heat dissipation holes extend radially along the disk body 1 to the outer circumferential surface of the disk body 1. When the magnet 6 generates heat during operation, this structure can reduce the operating temperature of the magnet 6 by 10-15℃, effectively preventing the attenuation of the magnetic properties of the magnet 6 due to high temperature.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
