Description
Technical Field
The utility model belongs to the technical field of axial fan technique and specifically relates to a structure of making an uproar falls in quiet leaf of high-speed fan and fan thereof is related to.
Background
Axial fan has big amount of wind, air supply distance advantage such as far away, can be applied to fields such as quick-witted case, electronic box, electric cabinet, but axial fan has the high shortcoming of noise simultaneously, can cause very big noise problem under high-speed operation, influences operational environment. Because a large air outlet speed is needed, the rotating speed is generally adjusted to be in a high state. After the air current got into the fan, under the effect of impeller, pressure rose, and high-speed air current can produce great interact when the quiet leaf of frame, leads to the striking dynamic height, and the air current strikes the marginal outflow of quiet leaf back from quiet leaf, will produce great indiscriminate stream, and then produces great noise. The interaction between the high-speed airflow and the outer frame stationary blade is one of the reasons for generating the aerodynamic noise of the high-speed fan.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a structure of making an uproar falls in quiet leaf of high-speed fan and fan thereof effectively combs the turbulent flow that the quiet leaf surface of adhesion produced when gaseous high-speed rotatory air-out flows, improves the gas flow and turns into the laminar flow, realizes the effect of noise reduction.
In order to solve the technical problem, the utility model provides a technical scheme is: the utility model provides a structure of making an uproar falls in quiet leaf of high-speed fan, includes the frame, and the frame inner circle is equipped with the quiet leaf that is annular evenly distributed, forms the ventiduct between quiet leaf, evenly is equipped with a plurality of convex closure on the quiet leaf.
The above technical scheme is adopted in the utility model, through the setting of a plurality of convex closure, when high-speed air current passes through quiet leaf, reduce the adhesion, the high-speed rotatory air current bypasses quiet leaf through the rectification of convex closure and flows from the ventiduct, effectively combs the adhesion to quiet leaf when gaseous high-speed rotatory is out, improves the gas flow and turns into the laminar flow, has reduced the indiscriminate flow phenomenon, realizes reducing the effect of the noise of fan operation.
The stator blade of the high-speed fan noise reduction structure is of an airfoil structure.
According to the high-speed fan stationary blade noise reduction structure, the convex hulls are strip-shaped and are arranged side by side along the wing-shaped front edges of the stationary blades. When the air current passes through the strip convex hull, the air current is baffled from the surface of the convex hull and finally bypasses the static blade to flow out, thereby reducing the turbulent flow generated by directly impacting the static blade, reducing the adhesion to the static blade and realizing the purpose of noise reduction.
In the high-speed fan stationary blade noise reduction structure, the outer end of the stationary blade is fixed on the outer frame inner ring, and the base is fixed at the inner end of the stationary blade. The base is used for the installation to set up the motor, and the rotatory air current that produces of motor drive flabellum flows through from the quiet leaf of base periphery, and quiet leaf realizes noise reduction effect through the design of convex closure.
The utility model also provides a fan, including motor and the flabellum of being connected with the motor and any one of above-mentioned technical scheme the quiet leaf of high-speed fan fall the structure of making an uproar, the motor is established on the base. The motor drives the fan blades to rotate to form high-speed airflow flowing axially, and the high-speed airflow flows through the stationary blades and then is rectified by the noise reduction structure, so that the generation of a turbulent flow phenomenon is reduced, and the effect of reducing the running noise of the fan is realized.
The utility model discloses the beneficial effect who gains is: the turbulent flow phenomenon generated by adhesion on the surface of the static blade when the high-speed airflow rotates to flow out is effectively combed, the convex hull improves the air flow and converts the airflow into laminar flow, and the technical effect of reducing the noise of the fan is realized.
