Description

Novel impeller of energy-saving fan

Technical Field

The utility model relates to a fan equipment technical field especially relates to a novel impeller of energy-conserving fan.

Background

The fan is a machine which can increase the gas pressure and convey gas by means of input mechanical energy, and is widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draught of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selecting grains; in the working process, a common motor drives an air compressor impeller, airflow axially enters a blade space from a fan, and rotates along with the impeller under the action of the impeller rotating at a high speed, energy is improved under the action of inertia, the airflow leaves the impeller along the radius direction, and the airflow does work by the generated centrifugal force.

At present, the impeller manufactured in the market generally adopts a 9-blade straight wing or arc wing structure, but the straight wing or arc wing structure does not meet the requirement of a rotating flow pattern structure, so that a flow channel and a wing structure in a blade are mostly disordered and changed flow channels, and the performances of the impeller such as flow, wind pressure, noise and the like are not good enough.
