Embodiment Construction

[0009] The present invention is described below in conjunction with accompanying drawing: with reference to accompanying drawing, a kind of square tube blower fan that facilitates engine cooling comprises engine 1, support, fan blade 2 and square tubular shell 3. 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 engine output shaft 11 forms an angle of 45° with the opening direction of the square tubular housing 3 . The rotation plane of the fan blade 2 is perpendicular to the engine output shaft 11, and the rotation plane of the fan blade 2 forms an angle of 45° with the opening direction of the square tubular shell 3. The section of wind blade 2 is airfoil. The inner circumference of the cross section of the square tubular shell 3 is a rectangle, the length of this rectangle is slightly larger than the maximum outer diameter of the fan blade 2 when the engine output s...

Abstract

The invention discloses a square pipe fan convenient for engine cooling, and relates to a fan. The square pipe fan comprises an engine, a bracket, a blade and a square pipe type shell. An output shaft of the engine and an opening direction of the square pipe type shell are formed to an acute angle. A rotating plane of the blade is perpendicular to the output shaft of the engine, and is formed to an acute angle with the opening direction of the square pipe type shell. The inner periphery of the cross section of the square pipe type shell is rectangular; the length of the rectangle is slightly greater than the maximal outer diameter of the blade rotating along with the output shaft of the engine; and the width of the rectangle is slightly greater than a product between the maximal outer diameter of the blade rotating along with the output shaft of the engine and the sine of the acute angle formed by the rotating plane of the blade and the opening direction of the square pipe type shell. A rotating center of the blade is positioned on a geometric center line of the opening direction of the square pipe type shell. The engine is positioned at the downstream of an air flow. Compared with a traditional axial flow fan, the square pipe fan is much smaller in section under the condition of equal flow, so that the square pipe fan is convenient to be installed in a narrow space.

Description

technical field [0001] The invention relates to a square-tube fan which is convenient for engine cooling, and 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 object 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 and is convenient for engine cooling. [0004] The technical proposal of the present invention is: a square-tube blower fan convenient for engine cooling, which includes an engine, a bracket, fan blades and a square-tube casing. The engine is installed in the inside of the square tubular casing thr...
