Description

High-efficient axial fan for vehicle

Technical Field

The utility model belongs to the technical field of axial flow fans, and particularly relates to an efficient vehicular axial flow fan.

Background

The axial flow fan is a rotating machine for improving the pressure of circulating airflow, and gas is loaded by rotation of blades and is forced to move axially, namely the gas enters axially and is discharged axially. It features that when working, the gas flows axially, and has low pressure and high flow rate.

The existing axial flow fan for the vehicle has lower efficiency and higher noise, and the main reasons for causing the problem are as follows: firstly, the leaf profile is not optimized sufficiently; and secondly, the problem of insufficient matching of a blade top current collector and a static current collector on a mesh enclosure is solved, and therefore the efficient axial flow fan for the vehicle is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a high-efficiency axial flow fan for a vehicle, which aims to solve the problems that the conventional axial flow fan for the vehicle, which is proposed in the background art, has low efficiency and high noise and is mainly caused by the following reasons: firstly, the leaf profile is not optimized sufficiently; secondly, the cooperation between the leaf top current collector and the static current collector on the mesh cover is insufficient.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a high-efficient automobile-used axial fan, includes impeller and screen panel, the inboard of screen panel is provided with the screen panel wheel hub of integral type, be provided with the radial rib of integral type between screen panel wheel hub and the screen panel, the outside of radial rib is provided with the circumference rib of integral type, the impeller includes impeller wheel hub, blade and current collector, impeller wheel hub's the outside is provided with the blade of integral type, the outside at the blade is installed to the current collector, the top edge of screen panel is provided with the static current collector of integral type.

Preferably, the gap reserved between the blade tip current collector and the stationary current collector is approximately S-shaped.

Preferably, the inner side of the mesh enclosure is provided with three circumferential ribs.

Preferably, the blade and radial rib sections are of an airfoil design.

Compared with the prior art, the utility model has the beneficial effects that:

(1) efficient hook type blade, the blade is whole to be optimized according to the fluid trend, and whole molding closely resembles the hook, and each cross-section adopts the airfoil design, and efficiency is higher, can reduce the electric power that wind wheel in use consumed, and the clearance design between air intake wind wheel collector and the screen panel collector is approximate to "S", mainly has the effect in two aspects: firstly, the design can prevent the backflow of the blade top from pouring into an inlet to a certain degree, and secondly, because the front edges of the two current collectors are kept flat, the backflow of the blade top can be blocked to a certain degree by airflow collected to the inlet of the fan, the section molded line of the current collector of the mesh enclosure is horizontal, the section molded line of the current collector of the wind wheel slightly upwarps, the backflow of the blade top is blocked by airflow at the outlet of the wind wheel, and the consumption of energy is reduced;

(2) the design of three circles of circumferential ribs is adopted in the circumferential direction of the mesh enclosure, so that the loss caused by the circumferential ribs is reduced;

(3) the radial ribs adopt a wing-shaped bending design, the efficiency of the wind wheel is improved as much as possible, and the radial ribs are arranged in a staggered mode.
