Description

Technical Field

[0001] This utility model relates to the field of new energy motor technology, and in particular to a turbine cooling fan structure for a new energy motor. Background Technology

[0002] Electric motors, especially new energy motors, are the core of power drive units and are currently being widely and rapidly researched and developed. Their size is getting smaller and their efficiency is getting higher. At the same time, the market is also looking forward to motors that are smaller, more efficient, more stable, and more adaptable to various environments.

[0003] Electric motors, especially small precision and high-efficiency motors, accumulate a lot of heat when operating at high power continuously. Some motors, due to the limitations of their installation location, have difficulty implementing good heat dissipation channels. Traditionally, motors that rely on air circulation for heat dissipation usually use centrifugal fans at their tail end. However, the heat dissipation channels of existing motors are relatively simple and usually only dissipate heat for the motor housing. The heat dissipation efficiency of the rotor, stator coils, and windings, which are the core components of the motor, is not high. Summary of the Invention

[0004] The purpose of this utility model is to provide a turbine-type cooling fan structure for a new energy motor, so as to improve the heat dissipation efficiency of the motor for the rotor, stator coils and windings, thereby improving its stability and lifespan.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A turbine-type cooling fan structure for a new energy motor includes a volute and a mounting part. The volute and mounting part have a hollow structure inside, and a fan assembly is arranged inside. A circular opening is opened at the center of the front end of the volute. The fan assembly includes a base plate, blades, and a front cover plate. The blades are centrifugal diverging turbine structures, with multiple blades arranged in a central row and clamped inside the base plate and the front cover plate. The base plate is fixedly connected to one end of a rotating shaft by bolts, so that the rotating shaft rotates synchronously with the fan assembly. An opening is provided at the center of the mounting part, which is used to guide the airflow generated by the rotation of the fan assembly to the rotor and stator components inside the new energy motor.

[0007] Furthermore, the volute has a connecting structure at its circular opening for connecting the air intake pipe.

[0008] Furthermore, the front cover plate has an opening at the center of its front end, and a flange structure is provided at the opening. The flange structure kit is arranged inside the circular opening of the volute.

[0009] Furthermore, the front end of the volute has a frustum-shaped beveled structure, and the front cover plate also has a beveled structure, so that the two are in a non-contact but fitted state.

[0010] Furthermore, the fan assembly is placed within the internal space constructed by the volute and the mounting portion, and the cross-section of the fan assembly is trapezoidal.

[0011] Furthermore, the outer diameter of the front cover is larger than the outer diameter of the base plate.

[0012] Furthermore, the outer ring of the base plate is provided with notches and holes.

[0013] Furthermore, the notched holes are positioned between adjacent blades.

[0014] Furthermore, a limiting groove is arranged on the rear side of the mounting part, which can accommodate the stator component and fix the two in place.

[0015] Furthermore, a structural component is arranged at the limiting groove, and a bearing is arranged at the center of the structural component, the bearing being used to install the rotating shaft.

[0016] Furthermore, the structural component is provided with multiple through holes.

[0017] Compared with existing technologies, this solution has the following advantages:

[0018] This solution proposes a turbine-type cooling fan structure for a new energy motor. The main body of the fan assembly adopts a centrifugal structure to implement airflow cooling. The fan assembly is arranged in the internal space constructed by the volute and the mounting part, thus realizing the introduction of airflow from the front end of the volute and the direct delivery of airflow to the rotor and stator components. This enables efficient airflow cooling of the motor's internal components and is suitable for various motor types.

[0019] The fan assembly adopts a built-in arrangement structure, which can reduce the impact of foreign objects on the rotation of the fan assembly. It can centrifuge some dust, impurities or moisture in the air, causing them to impact the inner wall of the volute, thus reducing the impact on the rotor and stator components.

[0020] The circular opening of the volute can be used to connect the intake pipe, which can effectively introduce cold air in extreme installation environments and improve the flexibility of motor installation.

[0021] The fan assembly has a trapezoidal cross-section and uses centrifugal operation through the blades, which can reduce its size, improve its air delivery efficiency, and reduce noise, thus enabling the motor to be used in a variety of environments. Attached Figure Description

[0028] refer to Figures 1 to 6 A turbine-type cooling fan structure for a new energy motor. The new energy motor includes a rotating shaft 10, a rotor component 11, and a stator component 12. The rotating shaft 10 is connected to the front and rear bearings and the housing, and the rotating shaft 10 and the rotor component 11 rotate smoothly at the center of the stator component 12.

[0029] A heat dissipation assembly 2 is arranged at the rear end of the rotating shaft 10. The heat dissipation assembly 2 includes a volute 21 and a mounting part 22. After the volute 21 and the mounting part 22 are assembled, they have a hollow structure similar to a drum. A fan assembly 3 is arranged inside the hollow structure. A circular opening 23 is opened at the center of the front end of the volute 21 for air intake. In some embodiments, a connecting structure or a splicing structure is provided at the circular opening 23, which can be used to connect an air intake pipe. The air intake pipe can be connected to a specific location of the entire device to facilitate the acquisition of clean, cool air.

[0030] The fan assembly 3 includes a base plate 31, blades 32, and a front cover plate 33. The base plate 31 is installed on the front end of the shaft 10 by screws, so that the base plate 31 and the shaft 10 can rotate synchronously as a whole. The seven blades 32 are arranged in a centrally aligned turbine structure and are clamped and arranged inside the base plate 31 and the front cover plate 33. The base plate 31, blades 32, and front cover plate 33 can be stamped from thin metal sheets. The blades 32 can be integrally installed by interference fit with the corresponding concave holes of the base plate 31 and the front cover plate 33 through the protrusions on both sides. Alternatively, the three can be fixedly installed by spot welding on this structure, thus realizing the synchronous rotation function of the fan assembly 3 and the shaft 10. When necessary, the dynamic balance structure of the fan assembly 3 should be checked and corrected to enable it to rotate smoothly at high speed.

[0031] The rear end of the mounting part 22 is connected to the stator component 12. Specifically, the mounting part 22 has an opening at its center. The opening is used to guide the airflow generated by the rotation of the fan assembly 3 to the rotor component 11 and the stator component 12. When it is working, the airflow is used to perform heat dissipation and cooling operations on them.

[0032] To improve installation efficiency, increase structural strength, reduce parts, and make the entire motor more integrated, the mounting part 22 can be made of aluminum alloy casting and precision machining. A limiting groove 24 is arranged on the rear side of the mounting part 22. Specifically, the limiting groove 24 is arranged on one side of the opening of the mounting part 22 or on the opposite sides. The limiting groove 24 can accommodate and clamp the outside of the stator component 12 and prevent the two from rotating or sliding, so that the two can be fixedly installed.

[0033] A structural component 23 is arranged at the limiting groove 24 of the mounting part 22. A bearing is arranged at the center of the structural component 23. The bearing is used to install the rotating shaft 10. In order to better guide the airflow, multiple through holes 25 are provided on the structural component 23.

[0034] For the fan assembly 3, an opening 35 is provided at the center of the front end of the front cover 33. A flange structure is provided at the opening 35, which is fitted inside the circular opening of the volute 21, allowing the airflow from the circular opening to be completely guided into the interior of the fan assembly 3. To improve efficiency and reduce space occupation, the front end of the volute 21 has a frustum-shaped bevel structure, and the front cover 33 also has a bevel structure, ensuring that the two are in a non-contact but fitted state. The fan assembly 3 is placed within the internal space constructed by the volute 21 and the mounting portion 22. The fan assembly 3 is positioned close to the front end of the internal space, with a certain amount of space reserved at the rear end to accommodate the air input through the fan assembly 3, and to make the airflow input to the rotor component 11 and stator component 12 more balanced. The cross-section of the fan assembly 3 is a trapezoidal structure (see reference). Figure 5 The blades 32 also gradually decrease in height from the inside to the outside. The outer diameter of the front cover plate 33 is larger than the outer diameter of the bottom plate 31. The outer edge of the front cover plate 33 is basically in contact with the inner wall of the volute 21. Therefore, the airflow will be guided to the rear side of the bottom plate 31. In order to better facilitate the airflow extraction, notches 34 are arranged on the outer ring of the bottom plate 31. The notches 34 are arranged between adjacent blades 32 to improve the airflow extraction efficiency.

[0035] In actual use, the fan assembly 3 is fixedly installed with the rotating shaft 10 to achieve synchronous rotation of the rotating shaft 10, the rotor component 11 and the fan assembly 3. Under its centrifugal force, the fan assembly 3 can efficiently guide the airflow to the rotating shaft component 11 and the stator component 12 to achieve efficient heat dissipation and cooling.

[0036] In summary, the turbine cooling fan structure of this new energy motor adopts a centrifugal fan assembly to implement airflow cooling. The fan assembly is arranged in the internal space constructed by the volute and the mounting part, thus realizing the introduction of airflow from the front end of the volute and the direct delivery of airflow to the rotor and stator components. This enables efficient airflow cooling of the motor's internal components and is suitable for various motor types.

[0037] The fan assembly adopts a built-in arrangement structure, which can reduce the impact of foreign objects on the rotation of the fan assembly. It can centrifuge some dust, impurities or moisture in the air, causing them to impact the inner wall of the volute, thus reducing the impact on the rotor and stator components.

[0038] The circular opening of the volute can be used to connect the intake pipe, which can effectively introduce cold air in extreme installation environments and improve the flexibility of motor installation.

[0039] The fan assembly has a trapezoidal cross-section and uses centrifugal operation through the blades, which can reduce its size, improve its air delivery efficiency, and reduce noise, thus enabling the motor to be used in a variety of environments.
