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

The invention provides a square tube-shaped fan and relates to a fan. The square tube-shaped fan comprises an engine, a support, a fan blade, a square tube-shaped housing and a flow deflector. The engine is mounted inside the square tube-shaped housing through the support. Four flat plates are encircled to form the square-tube-shaped housing. The rotating plane of the fan blade is perpendicular to two parallel flat plates of the square tube-shaped housing and an acute angle is formed between the rotating plane of the fan blade and each of the other two parallel flat plates of the square tube-shaped housing. The engine is located upstream of airflow. The flow deflector is mounted at the outlet of the square tube-shaped housing. Compared with a traditional axial-flow fan, in case of the same flow, the sectional area of the square tube-shaped fan is much smaller, and therefore, the square tube-shaped fan can be mounted in a narrow space conveniently.

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...
