BSBY_f010 DC fan manufacturers brand [motor] Shenzhen Xin Xin speeding speeding Motor Co., Ltd. has always adhere to the "people-oriented" management philosophy and "pragmatic innovation" concept of development, the implementation of scientific management. Products are exported to foreign markets, and to require the production of various products according to customer's special. The company's own MDOVPD (Modern speeding) brand in the community has been recognized by our customers and trust. The product has passed the UL, CE, ROHS, CCC and other safety certification, and is widely used in communications equipment, network chassis cabinets, automation machinery and equipment, medical equipment, stage equipment, LED display, welding machine and other ancillary equipment services. DC fan first brand research and production businesses Xin speeding is a professional fan, blower fan and research and development production and marketing enterprises. Its products quality protection, aftermarket with more confidence. While speeding Xin Xiao Bian today to introduce awareness information relative itch questions about the radiator fan unit and extending computing. If the wind is calculated by cubic feet, the unit is CFM; if you press m to count, that is CMM. Air volume units are often used radiator CFM (approximately 0.028 m3 / min). 50 × 50 × 10mm CPU fan will generally reach 10 CFM, 60 × 60 × 25mm fan to achieve 20-30 CFM. In the same heat sink material, the air flow is a measure of the ability of air-cooled heat sink of the most important indicators. Obviously, the greater the amount of air which the radiator cooling capacity is also higher. This is because the air in the heat capacity ratio is certain, centrifugal fan greater air flow, that is, more air per unit of time can take more heat. Of course, the same air volume flow of the cooling effect of the wind the way. Air volume and pressure air volume and pressure are two opposing concepts. In general, to design air volume fan, it is necessary to sacrifice some pressure. If the fan can bring a lot of air flow, but the pressure is small, the wind can not blow the bottom of the radiator (which is why some high fan speed, air volume is large, but the cooling effect is good reason). Conversely, a large wind pressure, air volume is small, there is not enough cold air subjected to heat exchange with the heat sink, the cooling effect will be poor. General requirements of aluminum fin heat sink fan pressure is large enough, and the copper heat sink fin fan air volume is required to be large enough; more dense fin heat sink fins relatively sparse compared to the heat sink, the need greater pressure fan, otherwise poor air flow between the fins, the cooling effect will be greatly reduced. Fan speed is the number of revolutions per minute of the fan blades, the unit is rpm. Fan speed is determined by the motor inside the coil turns, voltage, number of fan blades, inclination, height, diameter and bearing systems. Fan speed and quality are not necessarily linked. The fan speed can be carried out by the internal speed signal measurement can also be measured by external (external measurement is to see how fast the fan speed with the other instruments, internal measurements directly into the BIOS can see, you can also look through the software. Internal relatively large number of measurement error). Because as the ambient temperature changes, is sometimes necessary to meet the needs of different speed fan. Xin speeding remind you, the fans do not wind the bigger the better, but a relative. DC fan to buy the preferred business Xin speeding, for more information about the fan speed of the fan, please visit the official website Xin, or to inquire.
