Types of DC axial fans

A DC axial fan uses direct current to move air in the same parallel direction as the airflow. There are many types of DC axial fans based on their construction and application.

• Normally Open DC Axial Fans

  A normally open fan will run whenever there is power. It isn't always a good choice for a part because it can use up battery power at some point.

• Smart DC Axial Fans

  A smart fan can change its speed depending on the temperature or humidity. This will let it use less battery power. It can also make the system quieter.

• Normally Closed DC Axial Fans

  A normally closed fan will only run when there is power. This means that it can be better to save energy during here but may not be as good at cooling.

• Dual-Speed DC Axial Fans

  A dual-speed fan has two speeds to pick from. It can be low or high. It is normally open and can use less power in the low-speed setting.

• PWM Control DC Axial Fans

  A PWM fan will let the duty cycle change its speed. Duty cycle is how long the fan runs verses not running. It can be quieter and use less power in comparison to a normally open fan.

• IP65 Rated DC Axial Fans

  An IP65 rated fan will be dust tight and can handle water from any direction. It will work in wet or damp places but not under water. The seal means it will not let water inside of the motor.

• Flow Control DC Axial Fans

  A flow control fan can change its speed based on the flow. It might be called a delta fan. It has the ability to move more air based on what is needed.

• Sensor Control DC Axial Fans

  A sensor control fan will change speeds based on sensors detecting heat or other thing. It can be more energy efficient depending on how many sensors are around to tell it to go faster or slower.

Specifications and maintenance of DC axial fans

Specifications

• Flow Rate: The air volume or amount of airflow produced by the fan in a typical unit per minute (CFM) or cubic meter per hour (m³/h).
• Speed: The rotating speed of the fan, usually measured in revolutions per minute (RPM), which determines the frequency of the airflow.
• Power Consumption: The power consumption of the fan, typically in watts (W), which represents the amount of electrical power it uses.
• Operating Voltage: Direct Current (DC) fans operate within a specific voltage range, such as 5V, 12V, 24V, etc. Different voltages may affect the fan's speed and performance.
• Noise Level: The noise generated by the fan during operation, typically measured in decibels (dB), which indicates the loudness of the fan.
• Fan Blade Design: The shape and number of the fan blades, including factors like the airfoil design, width, and angle, can affect the airflow and pressure generated by the fan.
• Motor Type: The type of motor used in the fan, such as brushed or brushless DC motor, may influence the fan's performance, reliability, and lifespan.
• Operating Temperature Range: The temperature range within which the fan can operate normally, ensuring its application in different environmental conditions.
• Connector and Wiring: DC fan connectors and wiring, such as 3-pin or 4-pin connectors, determine how the fan is connected to the power source and control system.

Maintenance

• Regular power-off cleaning: Before cleaning the DC fan, first, shut down or turn off the power. This can prevent accidental electric shock or injury during the cleaning process.
• Dust removal: Use a soft brush or a dust blower to gently brush or blow away the dust on the surface of the fan and the blade. Be careful not to use excessive force to avoid damaging the fan or the leaves.

Scenarios of DC axial fans

The following are some common usage scenarios of a DC axial fan.

• Electrical Appliance Cooling

  A frigerator uses a DC cooling fan to exhaust heat from the condenser coil. The refrigerator operates a condenser coil outside the refrigerator compartment, where it can release heat with the help of a DC cooling fan. The centrifugal DC fan makes this possible by moving the heat into the surrounding air, thereby keeping the refrigerator cool.

• Computer Cooling

  DC axial cooling fans are typically placed in the computer casing and power supply unit to facilitate the cooling of computers. They allow heat generated by the computer components, like the CPU, to dissipate quickly and prevent overheating. Moreover, the CPU DC fans permit continuous airflow within the computer casing to prevent the buildup of hot air.

• Car Automobiles

  Many cars are fitted with DC axial fans to aid in cooling the engine and radiator. The function of the DC fan is to maintain the right operating temperature of the engine by ensuring that it doesn’t overheat during use. This, in turn, improves the overall longevity of the car and enhances its performance.

• Server Farms and Data Centers

  A data center DC fan keeps the servers in a data center cool. If the servers are allowed to overheat, it could lead to server failure and disruption. By using a 12v DC fan, the servers can be kept cool, their performance maintained, and their longevity improved.

• Ventilation in Buildings and Infrastructure

  The axial DC fans assist in ventilating buildings and other enclosed spaces. They achieve this by moving large volumes of air. Moreover, they are energy efficient when compared to AC fans, which make them suitable for lengthy operations.
