Abstract

The invention discloses an automatic heat dissipation type straight cylinder axial flow fan. The automatic heat dissipation type straight cylinder axial flow fan comprises a second chamber, a transition section, a first chamber, multiple air inlets, a motor, a wind wheel, a wind guide ring and a filtering warehouse, wherein the second chamber, the transition section and the first chamber are formed from one end of a shell body to the other end of the shell body ; the multiple air inlets are uniformly distributed in the end face of the other end of the shell body in a ring-shaped mode; the motor and the wind wheel are coaxially arranged in the second chamber; the wind guide ring is a ring-shaped plate body, the radial direction of the wind guide ring is arc-shaped, the opening of the arc faces the first chamber, the big ring end of the wind guide ring is fixedly arranged on the side wall which is close to the other end of the shell body, the small ring end of the wind guide ring is arranged in a mode of expanding towards the tail end of the motor, and the length of the radial direction of the wind guide ring is smaller than 1 / 5 of the diameter of the cross section of the second chamber; the filtering warehouse is a cylinder of which two ends are provided with openings, one end of the filtering warehouse is arranged on the end face of the other end of the shell body in a clamping mode, and the multiple air inlets are formed in the filtering warehouse in a clamping mode. According to the automatic heat dissipation type straight cylinder axial flow fan, synchronous heat dissipation can be conducted on the motor of the axial flow fan in real time, it is guaranteed that the motor is always at a normal working condition temperature, and the service life of the axial flow fan is prolonged.

Description

technical field [0001] The invention relates to an automatic heat dissipation straight cylinder axial flow fan. Background technique [0002] Axial flow fans generally include a wind wheel and a motor. The middle part of the wind wheel is press-fitted on the outer rotor of the motor. The outer rotor of the motor rotates to drive the wind wheel to rotate. The gas is agitated by the blades in the wind wheel to move in the axial direction. In order to prevent the wind wheel from injuring people when the wind wheel rotates, a mesh cover is generally provided to wrap the wind wheel to prevent people from touching the wind blades on the wind wheel. [0003] In the prior art, the motor on the axial flow fan is arranged on the air inlet duct of the axial flow fan, and the cross-sectional diameter of the motor is equivalent to the cross-sectional diameter of the hub of the wind wheel, so that the wind on the air duct basically passes around the motor, and the There is no good heat d...
