Description
Technical Field
The utility model belongs to the technical field of radiator fan technique and specifically relates to a rectifier screen panel fan.
Background
The blades of the axial flow fan push air to flow in the same direction as the shaft, and the impeller and the propeller of the axial flow fan are somewhat similar, so that the flow direction of most air flows is parallel to the shaft in operation. The axial flow fan consumes the lowest power when the inlet airflow is free air of 0 static pressure, and the power consumption is increased along with the rising of the counter pressure of the airflow when the axial flow fan is operated. Axial fans are usually installed in cabinets of electrical equipment and sometimes integrated in motors, and are widely used because they are compact in structure, save a lot of space, and are convenient to install. Axial fans are often used as heat dissipation fans in cabinets, and the like. Present fan is when the rotatory air supply of flabellum, and the air current gets into from the edge of fan, because in service, the influence of factors such as the inside air flow of equipment such as quick-witted case, electricity cabinet, wind speed, the air inlet air is more disorderly, and the air inlet air is more irregular, produces great noise easily, influences equipment and uses.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rectification screen panel fan, the air current passes through the rectification of rectification screen panel from the air inlet side of fan body for admit air more perfect, accomplish the air inlet law, reduce the noise that produces because of the turbulent flow, improved the flow of fan.
In order to solve the technical problem, the utility model provides a technical scheme is: the utility model provides a rectification screen panel fan, includes the fan body, installs the rectification screen panel in the air inlet side of fan body, and the inner circle ring of this rectification screen panel is equipped with the rectification root strip, and the rectification root strip is connected with hollow air inlet circle.
The utility model adopts the above technical scheme, the air is blown by the fan blade rotation of the fan body, forms the air current and enters from the rectification net cover, and the flow direction of the air current is regular through the straight line rectification of the rectification root; the hollow air inlet ring can reduce the obstruction to the air flow and improve the flow of the fan through the air flow; the air flow rectified by the rectification mesh enclosure effectively reduces turbulent flow and turbulent flow, and solves the problem of high noise of the existing fan. The air inlet rule is accomplished to this fan, perfects the condition of admitting air, has reduced the noise of fan.
In the rectification mesh enclosure fan, the rectification root strips are arc-shaped and are uniformly and annularly arranged on the inner ring of the rectification mesh enclosure. The arc-shaped rectifying root strips can enable air flow to enter an air supply duct of the fan along the surface of the arc-shaped rectifying root strips in a rotating mode when fan blades of the fan supply air in a rotating mode, so that obstruction is further reduced, turbulent flow of the air flow is reduced, and noise generated by the fan is further reduced.
In the rectification mesh enclosure fan, the air inlet ring and the fan body are coaxially arranged. The air inlet ring and the fan body are coaxial, and air flow at the axis passes through the air inlet ring and can uniformly enter a channel formed by the rotation of fan blades of the fan, so that the air inlet rule is realized, the generation of turbulent flow and turbulence is reduced, and the aim of reducing the noise of the fan is fulfilled.
In the rectification mesh enclosure fan, the end face of the rectification mesh enclosure is provided with the buckle, and the rectification mesh enclosure is detachably connected with the fan body through the buckle. The rectification screen panel is connected rapidly with the fan body, and it is nimble convenient to use, installs fixed fan earlier, and rethread buckle can be fast with the rectification screen panel connection on the fan body of fan.
The utility model discloses the beneficial effect who gains is: the air inlet rule is realized to the straight line rectification of air current through the root of the rectification of rectification screen panel, and the condition of admitting air is more perfect, effectively reduces the turbulent flow, reduces the noise of fan and promotes the fan flow.

Description of reference numerals: the fan comprises a fan body 1, a rectification mesh enclosure 2, a rectification root strip 21, an air inlet ring 22 and a buckle 23.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to 3, a rectification mesh enclosure fan includes a fan body 1, a rectification mesh enclosure 2 is installed on an air inlet side of the fan body 1, a rectification root strip 21 is annularly arranged on an inner ring of the rectification mesh enclosure 2, and the rectification root strip 21 is connected with a hollow air inlet ring 22.
The rectifying root strips 21 are arc-shaped and are uniformly arranged on the inner ring of the rectifying net cover 2 in a surrounding manner. The air inlet ring 22 is coaxially arranged with the fan body 1. The end face of the rectification screen panel 2 is provided with a buckle 23, and the rectification screen panel 2 is detachably connected with the fan body 1 through the buckle 23.
The utility model discloses when concrete implementation, the air flow direction of fan when operation for installing the rectification screen panel is shown to the arrow as fig. 2. The fan body 1 works, the fan blades rotate to supply air, and the rectification mesh enclosure 2 on the air inlet side is connected to the fan body 1 through the buckle 23. Air enters the rectification screen from the outer side of the rectification screen 2, and is rectified by the rectification root strips 21 and the air inlet ring 22, so that the airflow entering from the air inlet side and flowing out from the air outlet side of the fan becomes regular, the air inlet condition is more perfect, turbulent flow and turbulent flow are reduced, and the noise generated in the operation process of the fan is integrally reduced.
In summary, the present invention has been made to practical samples according to the description and the drawings, and after a plurality of use tests, the utility model can be proved to achieve the expected purpose, and the practical value is undoubted. The above-mentioned embodiments are only used to conveniently illustrate the present invention, and are not to the limit of the present invention in any form, and any person who knows commonly in the technical field has, if not in the scope of the technical features of the present invention, utilize the present invention to make the equivalent embodiment of local change or modification, and not to break away from the technical features of the present invention, and all still belong to the technical features of the present invention.
