Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a highly stable axial flow fan. Background Technology

[0002] In an intelligent cooling engine system, the cooling fan is an important component. The cooling fan mainly consists of fan blades, fan cover, motor, etc. The motor drives the fan blades through the motor shaft to blow air for heat dissipation. The fan cover is used to protect the motor and fan, prevent debris from entering, and also to guide the air to help cool the fan.

[0003] In related technologies, a fan shroud with publication number CN107061371A includes an inner ring, an outer ring, and fan shroud guide vanes. The fan shroud guide vanes are connected between the outer ring and the inner ring. A motor mounting base is located along one side of the inner ring's circumference. A concave cable outlet notch is formed on the inner ring, and a corresponding cable outlet notch is formed along the other end of the outer ring's outer ring. A groove is formed along the circumference of the outer ring, and the inner wall of one side of the groove is the outer side of the outer ring. The four arc segments on the outer side of the groove are straight lines. An outer ring notch is provided on the circumference of the outer ring, and the outer ring notch is vertically located between the two fan shroud guide vanes. However, the fan shroud is fixed to the motor housing by screws. Under high temperature and high vibration environments, the screws are prone to loosening, causing mutual movement between the fan shroud and the motor housing. This results in interference and friction of the fan shroud, damage to the fan, reduced service life, and safety hazards. Utility Model Content

A hub is fixed on the rotating shaft of the motor, and a set of fan blades are evenly distributed on the outer circumference of the hub. The fan blades are integrally formed with the hub. A fan cover is also provided on the outer side of the housing. A guide vane is provided between the fan cover and the housing and is fixed to both. The guide vane, the fan cover and the housing are integrally formed.

[0007] Preferably, the outer circumferential surface of the housing is evenly distributed with protrusions, and the protrusions are provided with threaded grooves. A cover plate is fixed on the side of the motor away from the hub. The cover plate has an opening, and a locking bolt can pass through the opening and lock in the threaded groove to lock the cover plate onto the housing.

[0011] Preferably, eight guide vanes are evenly distributed on the outer circumferential surface of the housing.

[0012] Preferably, a set of heat dissipation grooves are provided on the wheel hub.

[0013] The beneficial effects of this utility model are mainly reflected in:

[0014] 1. The ingenious design, with the guide vanes, fan cover, and housing integrally molded, prevents screws from loosening under high temperature and high vibration environments, thus extending service life. Furthermore, the compact structure and rational layout offer wide applicability.

[0015] 2. The fan cover, housing, and guide vanes are all made of cast aluminum, which gives them good thermal conductivity, improves the heat dissipation performance of the motor, reduces the internal temperature of the motor, improves the durability of the motor and electronic components on the PCB board, and extends the service life.

[0016] 3. The locking bolts lock the cover plate onto the housing, which can accurately position and lock the motor. This connection method is stable and reliable, and is easy to disassemble, replace and maintain, greatly improving work efficiency. Attached Figure Description
