"24V DC Cooling Fan" Noise is increasingly focused on a lot of players, for the fans who are from the fan noise. A little bit of difference between the blade and will not cause a big impact, but to know that in fact the tiny vacuum region may be the biggest source of noise, many manufacturers are in the upper and lower blades no small effort, mainly through some fancy Small reformed to achieve better mute diversion effect. Openings or guide lines on the blades increase, the main purpose is to reduce the vibration caused by the blades due to the airflow. "24V DC Cooling Fan" Of course, reduces vibration and noise will be decreased, the air will flow more smoothly in accordance with a predetermined flow, achieve better cooling effect. Fan air pressure and air volume has been relatively easy to confuse the concept of many players, the simple, the pressure is the pressure of the wind, the greater the pressure, the greater the power of the wind, the more likely the chassis punching, dust-proof net and other parts blown through. The wind can be understood as the same time the air flow through the fan size, at the same time, you can exchange more airflow to enhance heat dissipation. Relationship between pressure and air flow is relative, at the same speed, the greater the fan pressure, then it's the smaller air volume, and vice versa. "24V DC Cooling Fan" at the same time if you want to improve the fan air volume and pressure, then in addition to the blade design, by increasing the speed of the method is relatively simple. However, the ensuing sound of blades of wind shear and friction bearings under high speed rotation sound and other noise problems are troublesome people.
