DC Fans

DC fans, also known as direct current fans, before being commonly used in computers, were derived mainly from automotive applications. When used in computers, they are used to draw air out of the interior and to drive cool air or exhaust warm air, for proper thermal management. More recently, the DC fan has become a highlighted product in the world of electronic cooling.CFM-7010-13-20 is a DC fan specifically designed to provide reliable performance and cost effectiveness. It is a low flow, high pressure fan and its assembly dimensions are 70mm size, with 13mm of thickness and 20mm of depth.

CFM-7010-13-20 Application Field and Working Principle

CFM-7010-13-20 is designed to their application in radio-frequency applications, such as control systems and other electronic equipment. This makes it suitable for healthcare equipment (front panel cooling fan for medical equipment, scanners, medical machinery), security applications (CCTV cameras, data acquisition and other security devices) and other closed environments (IR equipment, automation systems, HVAC systems and more).The CFM-7010-13-20 is composed by an impeller, drive motor, bearings to ensure its durability and a guard to protect the internal components from dust build-up. The motor is a brushless DC motor, commonly used in hardcore environments. This motor has no contact points, so there is no contact spark generated, making it ideal for applications that require no electrical interference.The working principle of CFM-7010-13-20 is simple. The impeller receives energy from the driving motor, which overcomes the frictional losses from the bearings and the guard to shift air from its surroundings. The motor is powered by electricity and the impeller is turned by it. Thus, the air flow is generated and sustained. The speed, in turn, is determined by the voltage applied across its terminal.

Conclusion

The CFM-7010-13-20 is an ideal and cost effective DC fan designed specifically for operation in the most demanding environments. It has high pressure and low airflow capacity and offers reliable performance. The brushless DC motor impeller generates the necessary air flow as per the applied voltage, providing stability and durability for its applications. Thus it is ideal for medical equipment, security applications, and other closed environments, offering dust protection with its robust construction.
