What is a bladeless fan?

Bladeless fan is an electric fan designed in the form of aerodynamics , in order to create a smooth flow of air without making any noise compared to conventional electric fans. Even, you can hardly see the fan blades when the device is operating.

This is the product of a British engineer named James Dyson introduced in 2009, so the bladeless fan has the English name Dyson Air Multiplier .

Working principle and structure of bladeless fan

The bladeless fan has a very simple structure and operating principle, specifically:

Structure

The structure of the bladeless fan consists of two main parts:

• Fan base : includes the cooling motor containing the fan blade.
• Annular : is the area that radiates the wind, oval or round in shape.

Working principle

The bladeless fan works on the principle of aerodynamics, that is, the airflow will move from an area of high pressure to a place of low pressure to form a cooling airflow.

Specifically, when power is supplied to the device, the motor (about 40W) inside the fan base will operate at high speed to draw air inside. Then, the airflow will be blown through the narrow slit (about 1.3mm wide) located on the annular ring.

Most annular rings are designed with a 16-degree curvature so this makes the airflow blowing through the narrow slit also have a 16-degree inclination. Not only that, this process also causes the area in front of the rim to reduce pressure, and at the same time, causes the air mass behind the annular ring to be strongly sucked with a flow up to 15 times higher than the flow that the engine sucks. gas inside.

Therefore, the airflow generated from the bladeless fan is very strong and quieter than the open-bladed fan we often use.
