DC Fans - PFR1212DHE-F00 Application Field and Working PrincipleDC Fans are a type of cooling device primarily used for dissipating energy in electronic circuits and components. They are driven by DC voltage and operate by utilizing an electric fan with an air flow that is directed around a specific component to be cooled. The motor of the fan draws a current and transforms it into a moving force, which then drives the fan blades. This produces a pressure differential in the airflow created by the fan, resulting in air being forced through the device in order to dissipate heat.The PFR1212DHE-F00 DC Fans are specifically designed for cooling on larger surface areas, such as in server racks and other enclosures. This fan is provided with a total of 20 blades, making it capable of delivering monolithic and impressive airflow that is ideal for cooling large open areas. The PFR1212DHE-F00 has minimal noise production, making it suitable for environments where noise is a major concern. It also boasts a sturdy construction and can withstand temperatures up to 40 degrees Celsius. Its dual-headed design further ensures the fan blades are able to reach the far edges of the cooling area, and the fan can operate at both low and high speeds, depending on the application.The PFR1212DHE-F00 DC Fan\'s working principle utilizes two basic forces, convection and thermodynamics. The convection is caused by the forced air passing over the device to be cooled, cooling it. The thermodynamics is where the heat generated by the device is absorbed by the air, thus cooling the surrounding area. As the fan blades spin and draw in the air, the pressure in the fan area is increased, resulting in air moving over the device and allowing heat to be absorbed. At the same time, this also causes a pressure drop in the fan\'s housing, resulting in the fan blades drawing in a fresh supply of air, thus cooling the device further.The PFR1212DHE-F00 DC Fan also benefits from its integrated temperature control system, which can automatically adjust the speed of the fan in order to maintain a specific temperature even in varying environment conditions. This ensures efficient cooling and also reliably minimizes power consumption, thus making the PFR1212DHE-F00 DC Fan a highly economical option for cooling larger areas. In conclusion, the PFR1212DHE-F00 DC Fan is a highly efficient and reliable choice for cooling large areas and is suitable for a variety of applications ranging from server racks to industrial machines and other equipment. The fan provides powerful yet quiet airflow and the integrated temperature control system ensures the fan is able to maintain a specific temperature even in varying conditions. The PFR1212DHE-F00 is also a highly economical choice that offers good value for money and great performance.
