[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1-2 As shown, a flow guide device for improving the heating of an electric motor 4 comprises a spherical cover 1, the rear side of the spherical cover 1 is connected to a spiral cover 2, the rear side of the spiral cover 2 is connected to a straight pipe 3, an electric motor 4 is arranged inside the spiral cover 2, a connecting shaft 5 is arranged at the rear side of the electric motor 4, a fan blade 6 is arranged at the front end of the connecting shaft 5, and the fan blade 6 is positioned inside the spherical cover 1.

[0022] The main function of the spherical cover 1 is to collect the airflow blown out by the fan blades 6 at the rear end of the motor 4, change the wind direction, and guide the airflow into the spiral cover 2, effectively collecting more airflow, improving the flow efficiency of the airflow, making the airflow more concentrated, and enhancing the cooling effect. The spiral cover 2 is responsible for guiding the collected airflow to enhance the cooling effect. The spiral cover 2 extends the flow distance of the airflow, making the airflow more fully in contact with the outer wall of the motor 4, and effectively improving the heat dissipation capacity. The straight pipe 3 is responsible for guiding the airflow to the front end of the motor 4, ensuring that the airflow can be evenly distributed to the front side of the motor 4. The straight pipe 3 provides a channel for gas in and out.

[0023] The following is a detailed description of the design of the above key components:

[0024] The inner wall of the spiral cover 2 is formed with a spiral groove, and the minimum diameter of the inner wall of the spiral cover 2 fits closely to the outer wall of the motor 4. The spiral groove design increases the airflow distance, ensuring more contact between the airflow and the outer wall of the motor 4, effectively improving heat dissipation. The minimum diameter of the inner wall can closely fit the outer wall of the motor 4, increasing airflow efficiency and also providing a fixed position.

[0025] The length of the spiral cover 2 is greater than that of the motor 4. Increasing the length of the spiral cover 2 can provide more space, allowing the airflow to have a longer flow path inside the spiral cover 2. At the same time, the front and rear ends of the spiral cover 2 are longer than the motor 4, which can effectively allow the airflow to pass through, effectively adjust the airflow distribution, and reduce the airflow dead zone.

[0026] A filter is provided inside the straight pipe 3. The filter can effectively filter impurities, prevent impurities from entering through the straight pipe 3, and protect the normal operation of the motor 4 and the fan blades 6.

[0027] The spiral cover 2 is made of metal, which provides the spiral cover 2 with good strength and durability, and also has a good heat dissipation effect.

[0028] A silicone pad is provided at the minimum diameter of the inner wall of the spiral cover 2. The silicone pad is used to enhance the tightness between the spiral cover 2 and the outer wall of the motor 4. The silicone material can fit well with the outer wall of the motor, increasing friction and preventing the spiral cover 2 from shifting and falling off due to vibration of the motor 4.

[0029] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
