DC Fans, or DC-powered fans, are an important component of many electrical and electronic systems. They are widely used in industrial, aerospace and military applications to provide cooling air to keep components from overheating. In addition to the cooling benefits, DC fans also serve to dissipate heat generated by other components in the system. DC fans are available in a range of sizes and configurations, each designed to meet specific requirements. This article will examine the 109BD24FA2, a specific model of DC fan, and discuss its application field and working principle.

The 109BD24FA2 is an AC-DC brushless fan with a 230VAC input and 24VDC output. It is a small fan designed to provide static and dynamic pressure, with a dynamic pressure of 100Pa. It has an operating temperature range of -10℃ to +70℃, and its speed can be controlled by varying the input voltage. The fan blades are made of plastic, and it is powered by a single-phase motor. The motor is connected to a control electronics board, which can be programmed to adjust the speed of the fan according to user preferences.

The 109BD24FA2’s primary application field is cooling in electronic systems. It is a suitable choice for cooling ICs, processors, PCBs, resistors, capacitors, semi-conductors, and other components that generate heat during operation. It is particularly suitable for use in tight spaces, as its small size and light weight enable it to be installed easily and quickly. The fan can also be used in applications where noise reduction is desirable, as its low noise level (26dBA) ensures an unobtrusive operation.

The 109BD24FA2’s working principle is based on the Bernoulli principle, which states that when a moving fluid (in this case, air) passes through a venturi (in this case, the fan’s blades), its pressure decreases. As the air passes through the fan’s blades and out of the fan, its pressure decreases, creating an area of low pressure. This area of low pressure consequently draws in more air from the environment, which also passes through the fan’s blades. This continual process results in a steady flow of air being drawn through the fan. As the speed of the fan is increased, the air pressure decreases, resulting in greater air flow.

The 109BD24FA2 is a reliable, energy-efficient choice for cooling a wide variety of electronic components. Its small size and light weight make it an ideal choice for tight spaces, while its low noise level ensures an unobtrusive operation. Additionally, its ability to be adjusted by changing the input voltage makes it a versatile and customizable option. In conclusion, the 109BD24FA2 is a reliable and efficient choice for cooling things such as ICs, processors, PCBs and semi-conductors.
