Abstract
The utility model provides a make things convenient for engine cooling's square manage -style machine, relates to a fan, including engine, support, fan blade and square pipe shape shell. The engine output axle becomes an acute angle with the opening direction of square pipe shape shell. The rotation plane of fan blade is perpendicular with the engine output axle, and the rotation plane of fan blade becomes an acute angle with the opening direction of square pipe shape shell. The cross section of square pipe shape shell be the rectangle interior week, maximum outer diameter when this rectangular length is a bit larger tham the fan blade and is rotated, the product of the sine of the acute angle that the opening direction of the maximum outer diameter when this rectangular width is a bit larger tham the fan blade along with the rotation of engine output axle and the rotation plane of fan blade and square pipe shape shell becomes along with the engine output axle. The center of rotation of fan blade lies in the geometric centre line of the opening orientation of square pipe shape shell. The engine is in the low reaches of air current. The utility model discloses the fan is compared with traditional axial fan, when the flow is the same the utility model discloses the section of fan wants much little, easy to assemble in narrow space.
Description
Technical field
Facilitate a square tube blower fan for engine cooling, relate to a kind of blower fan, particularly relate to a kind of square tube blower fan.
Background technique
Traditional axial-flow blower is columnar, and the plane of rotation of its blade is substantially vertical with the opening direction of shell, and external diameter is comparatively large, and sectional area is comparatively large, is inconvenient to the narrow space being installed on flat.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of square tube blower fan facilitating engine cooling being easily installed in flat narrow space is provided.
Technological scheme of the present invention is: a kind of square tube blower fan facilitating engine cooling, comprises motor, support, fan blade and square-tube-shaped shell.Motor is by the inside of support installing at square-tube-shaped shell, and support is connected with square-tube-shaped shell.The opening direction of engine output shaft and square-tube-shaped shell is in an acute angle.The rotational plane of fan blade is vertical with engine output shaft, the rotational plane of fan blade and the opening direction of square-tube-shaped shell in an acute angle.The section of fan blade is aerofoil profile.The inner circumferential of the transverse section of square-tube-shaped shell is rectangular, this rectangular length is a bit larger tham maximum outside diameter when fan blade rotates with engine output shaft, this rectangular wide product being a bit larger tham the sine of acute angle formed by maximum outside diameter when fan blade rotates with engine output shaft and the rotational plane of fan blade and the opening direction of square-tube-shaped shell.Fan blade can rotate neatly in square-tube-shaped shell.The center of rotation of fan blade is positioned in the geometric center lines of the opening direction of square-tube-shaped shell.Motor is in the downstream of air-flow.
For raising the efficiency, the minimum clearance between the maximum outside diameter that fan blade rotates and the inwall of square-tube-shaped shell is between 1 ~ 3mm.Fan blade is in square-tube-shaped enclosure completely.Formed by the rotational plane of fan blade and the opening direction of square-tube-shaped shell, acute angle is less than 60 °.
A kind of square tube blower fan of engine cooling that facilitates of the present invention is work like this, and driven by engine fan blade rotates, and then fan blade is extruded in the gas inspiration square-tube-shaped shell in front from the rear of square-tube-shaped shell.Because motor is in the downstream of air-flow, motor can be cooled fully.The minimum clearance of the maximum outside diameter rotated due to fan blade and the inwall of square-tube-shaped shell is less, the rotational plane of fan blade and the opening direction of square-tube-shaped shell in an acute angle, fan blade is extruded from the rear of square-tube-shaped shell after rotating and the gas in the angle of the right wall of fan blade and square-tube-shaped shell being accelerated to the angle of the left wall of fan blade and square-tube-shaped shell.
A kind of advantage of the square tube blower fan of engine cooling that facilitates of the present invention is: compared with traditional axial-flow blower, when flow is identical, the basal area of blower fan of the present invention is much smaller, and efficiency is similar with traditional axial-flow blower; Blower fan of the present invention is easily installed in narrow space.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram facilitating the square tube blower fan of engine cooling of the present invention, and Fig. 2 is the plan view of Fig. 1.In figure: 1 is motor, 11 is engine output shaft, and 2 is fan blade, and the movement locus at the tip of 21 expression fan blades, 3 is square-tube-shaped shell, and 4 represent streamlines.
Embodiment
Below in conjunction with accompanying drawing, the present invention is illustrated: with reference to accompanying drawing, a kind of square tube blower fan facilitating engine cooling, comprises motor 1, support, fan blade 2 and square-tube-shaped shell 3.Motor 1 is by the inside of support installing at square-tube-shaped shell 3, and support is connected with square-tube-shaped shell 3.The opening direction angle at 45 ° of engine output shaft 11 and square-tube-shaped shell 3.The rotational plane of fan blade 2 is vertical with engine output shaft 11, the rotational plane of fan blade 2 and the opening direction angle at 45 ° of square-tube-shaped shell 3.The section of fan blade 2 is aerofoil profiles.The inner circumferential of the transverse section of square-tube-shaped shell 3 is rectangular, this rectangular length is a bit larger tham maximum outside diameter when fan blade 2 rotates with engine output shaft 11, this rectangular wide product being a bit larger tham maximum outside diameter when fan blade 2 rotates with engine output shaft 11 and sin45 °.The center of rotation of fan blade 2 is positioned in the geometric center lines of the opening direction of square-tube-shaped shell 3.Motor 1 is in the downstream of air-flow.Minimum clearance between the maximum outside diameter that fan blade 2 rotates and the inwall of square-tube-shaped shell 3 is 2mm.It is inner that fan blade 2 is in square-tube-shaped shell 3 completely.
This blower fan is work like this: motor 1 drives fan blade 2 to rotate, and then fan blade 2 is extruded in the gas inspiration square-tube-shaped shell 3 in front from the rear of square-tube-shaped shell 3.Because motor 1 is in the downstream of air-flow, motor 1 can be cooled fully.
