Axial and lateral combination type fan blade

Abstract

A longitudinal-horizontal combined fan blade comprises a hub and axial blades uniformly distributed on the edge of hub. The invention is characterized in that the ends of axial blades are connected with an integral base ring; the horizontal blades are uniformly arranged on the face of base ring. The invention has simple structure, which can combine the horizontal blade of aerator with the blades of fan, to supply axial wind and horizontal wind, to improve the wind output.

Description

technical field [0001] The invention relates to a fan component, in particular to a composite vertical and horizontal fan blade capable of providing vertical and horizontal wind at the same time. Background technique [0002] The fan is a kind of air supply device, and the wind output by it can accelerate the flow of air and have the effect of heat dissipation. The most commonly used is an axial-flow fan for axially discharging pressurized airflow. The blades of the axial-flow fan are usually composed of a wheel hub and blades arranged at equidistant intervals on the periphery of the wheel hub. When the fan blade rotates, the blades arranged on the periphery of the wheel hub perform work on the gas by cutting wind and lifting force, and the generated wind pressure and flow are discharged axially from the fan blade. There is also a cross-flow fan that can discharge pressure airflow horizontally. The blades of the cross-flow fan are arranged on the surface of the wheel at int...

AI Technical Summary

Problems solved by technology

Whether it is an axial flow fan or a cross flow fan, its scope of application is greatly limited due to the influence of the direction of the wind.

In the era of increasing functions of modern products and becoming shorter and thinner in size, fans with a single axial or horizontal wind direction have become more and more difficult to adapt to the installation and use of modern short, thin and thin products.
