Description

Technical Field

[0001] The utility model relates to the technical field of axial fans, in particular to high-static-pressure axial fans. Background Art

[0002] A high-static-pressure axial fan is a type of axial fan specifically designed to maintain high efficiency under relatively high static pressure conditions. Such fans are typically used in systems that need to overcome significant air resistance, such as complex ventilation duct networks, industrial environments requiring strong exhaust, or commercial and residential ventilation systems that demand low noise and high efficiency. Existing high-static-pressure axial fans have certain drawbacks during use. When the static pressure of the fan is higher, the rotational speed of the motor is faster, which causes the motor to generate a large amount of heat during efficient operation. This heat accumulates inside the inner cylinder and is difficult to dissipate quickly, resulting in a decline in motor performance. When the fan drives air flow, dust carried in the air easily adheres to the inside of the fan, thereby affecting the performance of the fan and shortening its service life. For this reason, we propose a high-static-pressure axial fan. Summary of the Utility Model

[0023] Example 2: Refer to Figure 1 , 2 , 6.

When the drive motor 5 operates, the generated heat is absorbed by the heat absorption plate 402 and conducted to the heat dissipation fins 404 through the heat conduction plate 403 inside the second embedding groove 405. When the air reaches the inside of the first cylinder body 101, the heat on the surface of the heat dissipation fins 404 is taken away, thus realizing heat dissipation.
