The secrets of the radiator fan
Added:2016-11-09     Views:

Different types of fans due to different types of fan blades, area and angle, installed in different locations will have different effects. They believe that game player must ask, fan type, area and angle and the installation position will have what kind of effect? Today I will explain what are the important parameters of the fan, and their design will bring what effect

Fan principle and bearing principle

When it comes to the fans we have to say is the working principle of the fan, easy to understand, the fan is mainly composed of two parts of the stator and rotor, the stator mainly includes control circuit, bearing, coil. The rotor is composed of three parts: the fan blade, the magnet and the shaft.

The bearing can be divided into, the most common for oil, hydraulic bearing, ball bearing is long, there are other rifles and fluid dynamic bearing, ceramic bearing, magnetic bearing, ball bearing pressure.

There are many kinds of fan bearings, each of which has its own characteristics. We say common oil and ball bearings.

Oil bearing is the use of sliding friction sleeve bearings, the use of lubricating oil as a lubricant and drag reduction agent. Although the noise is low, the manufacturing cost is low, but the wear is serious, the life is much smaller than the ball bearing. And the use of a long time, due to the reason of oil seal, lubricating oil will gradually evaporate, and dust will also enter the bearing, causing the fan speed slow, noise and other issues.

Change the way of bearing ball bearing friction, rolling friction, this method is more effective to reduce the friction between bearing surfaces, effectively enhance the fan bearing life, it will prolong the service life of the radiator. The disadvantage is that the process is more complex, resulting in increased costs, but also bring higher work noise

Front and CPU fan pressure to be large

The front of the main chassis fan is responsible for providing cold air to the chassis, in the rear of the fan is placed in the hard disk drive cage location. In order to better heat dissipation inside the chassis. Similarly to the intensive design of fin radiator will blow through, netizens suggested selection of wind pressure of the heat dissipation of wind, a lot of game player will ask why to choose the big wind fan.

In short, the wind pressure is the pressure of the wind, the greater the wind pressure, the greater the power of the wind, it is easier to blow the chassis, dust and other parts of the network through. The air volume can be understood as the same time the size of the air flow through the fan, at the same time, you can exchange more air flow to enhance the cooling effect.

Fan blade inclination angle and curvature of the two factors will largely affect the wind pressure of a fan. The larger the blade inclination angle and curvature value, the greater the wind pressure at the same speed. The utility model is especially suitable for being used in the front part of the cabinet. The outer air can be more quickly through the enclosure of the chassis into the chassis

Large exhaust fan

The chassis air duct is in order to let the air circulation, efficient circulation in order to better ensure stable working environment inside the chassis, the front of the chassis fan at high air pressure by transporting better penetration to the hard disk inside the chassis. For the disposal of the rear, the fan is to large air volume, so as to allow the interior of the hot air out.

At the same speed, the greater the wind pressure of the fan, then it is smaller, and vice versa. If you want to improve the air volume and wind pressure at the same time, in addition to the design of the fan blade, by raising the speed of the method is relatively simple.

The fan blades are designed to ease the blade inclination angle and curvature, as well as a more number of blades designed to allow each blade to be exposed to an even larger air area, making it more airflow through the same time. NMB-B19 fans are loved by many players is also a product known to the wind. From the exterior, the majority of fans with large air volume have a greater number of blades and a more relaxed blade inclination angle for the characteristics.

Fan frame to avoid noise

Many fans believe that the fan frame only played a role in the fixed fan, so there will not be much difference. But in fact, due to the fan itself there are many problems such as vibration, so a fan with a good frame design can effectively reduce the noise generated by vibration and other aspects, resulting in a better mute effect. In addition to the fan itself using shock absorber design, some chassis fan fixing holes on the side plate is directly used method to reduce noise damping rubber nail problems brought by fan vibration. As a result, even if the player does not have a shock absorber design of the fan, but also can play a very good mute effect

Fan selection is not difficult

In fact, choose a suitable for their own fan products is not difficult. The fan used in the chassis can be roughly divided into two categories: wind pressure and air volume. General CPU fan and an air fan chassis will get more lenient fan to ensure a high pressure, and the chassis fan blades tend to rely on relatively thin to ensure the greatest possible wind also can observe the style through the game player fan on the packaging and the main performance parameters mentioned above to fast to determine whether a product is suitable for their own chassis in the choice of the fan.

For those of large size fan products, also need a practical game player to choose, after all, to increase the dimension of the fan, the vibration effect is more obvious, the comprehensive ability may not be the mainstream 12/350px fan is more. The CPU and other core hardware fan
