Fan blade working principle and design key points
We can't leave the fan in the summer. We know that the fan is not as cool as the air conditioner, not the air conditioner, so I want to buy it when I buy the fan. Therefore, the wind is very important, so what is the air volume of the fan? The user is very concerned about it. Only by understanding these can better choose a good fan. In addition, the fan blade is also very important for the air volume. Therefore, the design problem of the fan blade must also be understood. Let's take a look.
Electric fan air volume and working principle:
The amount of airflow depends mainly on two aspects: one is the size of the blades, and the other is the speed of the blades. Usually, the fan of the small wind blade turns fast, and the ceiling fan of the big wind blade turns slowly. In terms of power, with a motor with a large power, the fan has a large air volume and consumes a lot of power. Such as industrial exhaust fans, the amount of wind is very large.
Working principle: When the electric fan rotates, the inclined blades will continuously push the rear air to the front, so the wind is generated. When the blade rotates, centrifugal force is generated. Therefore, the wind is generated by the centrifugal force and guided by the blade. When the blade is at an angle of 45 degrees with the center line, the wind speed is the largest, and at 90 degrees, the wind is most dispersed.
For the sake of mechanics, the three fans can form a reasonable mechanical dynamics. When one blade does not have the dynamic potential energy, the other two pieces are in the potential energy state, and the two potential energy blades can easily drive one piece temporarily. Potential energy blades save power and save energy. The current mainstream fan page is mainly designed with 2 leaves, 5 leaves and 7 leaves.
Fan blade design:
1, wind speed
The speed of the wind speed depends on the speed of the fan blade, which is related to the size, shape and even height of the fan blade. Therefore, the design of the fan blade involves a lot of physics knowledge, not a simple one.
2, the amount of air
The air volume is mainly affected by the factors of area and wind speed. At the same speed, the curvature of the blade is larger, and the air volume and wind pressure of the fan are larger.
3, wind pressure
The wind pressure reflects the strong index of the fan. Generally, when the blade spacing is not too large, a multi-blade design scheme is adopted to avoid affecting the air volume and the wind pressure. At the same time, the number of blades is often the base, which is to maintain the entire fan system. Balance.
The wind flow is the air flow driven by the fan, which determines the wind blowing distance and area of the fan. It is mainly affected by the curvature of the fan blade. Generally speaking, the arc of the rotating bending can effectively concentrate the wind flow, so that the fan has good heat dissipation performance.
Type of fan blade:
1. The electric fan blades are divided according to the application, and there are separated forms, mixed flow type and axial flow type blades.
2. Centrifugal fans use centrifugal fans because of their high efficiency, large flow, uniform output flow, simple structure and convenient operation.
3. The mixed flow fan combines the characteristics of axial flow and centrifugal fan.
4, axial flow fan, also known as local fan, is a kind of fan commonly used in industrial and mining enterprises, it is different from the general fan, its motor and blades are in a cylinder, the shape is a cylinder, used for local ventilation . The feature is that the installation is convenient, the ventilation and ventilation effect is obvious and safe, and the air can be sent to the designated area by the air duct.
