Embodiment Construction

[0009] The present invention is described below in conjunction with accompanying drawing: With reference to accompanying drawing, a kind of square pipe blower fan comprises engine 1, support, blade 2, square pipe shell 3 and deflector 4. The engine 1 is installed in the inside of the square tubular casing 3 through a bracket, and the bracket is connected with the square tubular casing 3 . The output shaft of the engine 1 forms an acute angle with the opening direction of the square tubular casing 3 . The square tubular shell 3 is surrounded by four flat plates, and the four flat plates are parallel to each other. The rotation plane of the fan blade 2 is perpendicular to two parallel flat plates of the square tube-shaped casing 3 , and the rotation plane of the fan blade 2 forms an angle of 50° with the other two parallel flat plates of the square tube-shaped casing 3 . The output shaft of the engine 1 is connected with the fan blade 2 . The section of wind blade 2 is airfoil...

Abstract

A square-tube fan relates to a fan, which includes a motor, a bracket, fan blades, a square-tube casing and a guide vane. The engine is mounted inside the square tubular casing with brackets. The square tubular shell is surrounded by four flat plates. The rotation plane of the fan blade is perpendicular to the two parallel flat plates of the square tube-shaped casing, and the rotation plane of the fan blade forms an acute angle with the other two parallel flat plates of the square tube-shaped casing. The engine is upstream in the airflow. The deflector is installed at the outlet of the square tube housing. Compared with the traditional axial flow fan, the cross-sectional area of ​​the fan of the present invention is much smaller when the flow rate is the same, and it is convenient to be installed in a narrow space.

Description

technical field [0001] A square tube fan relates to a fan, in particular to a square tube fan. Background technique [0002] The traditional axial flow fan is cylindrical, the rotation plane of the blade is basically perpendicular to the opening direction of the shell, the outer diameter is large, and the cross-sectional area is large, so it is not convenient to install in a flat narrow space. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a square-tube fan that is conveniently installed in a flat narrow space. [0004] The technical solution of the present invention is: a square tube fan, including a motor, a bracket, fan blades, a square tube shell and a guide vane. The engine is installed in the inside of the square tubular casing through a bracket, and the bracket is connected with the square tubular casing. The output shaft of the engine forms an acute angle with t...
