Different fans and blowers are used in electronics like computers, laptops, CPUs, PSUs, etc., for cooling purposes. Each of those DC Blowers has a different way of working while the main purpose satays to blow air and promote ventilation.
The top 5 types of DC blowers you can use in your project include:
A DC blower fan comes in a slim and small form factor, taking are from the sides with larger surface areas and throwing it in the perpendicular direction of the air suction. Due to this, it provides good ventilation in tighter areas like the inside of a laptop or tablet computer.
Due to its small form factor, it consists of a power-efficient motor that also runs on the power from the source device, which uses it for cooling purposes.
An axial fan blower usually comes in a straight form factor with a round body. The name of this blower comes from the working principle. Since it moves air along the axis of the fan blades, it is known as an axial fan.
The working of this blower is simple since it pulls air from the back and pushes it from the front creating a healthy airflow. For a higher airflow, a bigger motor is necessary to push the fan blades, and that's why this fan often comes in large sizes.
A centrifugal fan is similar to a blower fan but works slightly differently. It is a mechanical device that moves air perpendicularly to the axis of fan impellers and does not use regular fan blades. Instead, it uses impellers that cover more surface area due to the curved design and pushes air farther away due to more centrifugal force.
The design of this blower is not straightforward since it comes in a comma-like design to force all the air through a relatively smaller opening.
Some applications require a fan but don't have enough space to fit the whole frame. The small blower or centrifugal fans don't make the right choice. That's where the frameless fans make a great choice. These not only utilize less space more efficiently but also come with benefits like:
Often these fans have the motor attached to the frame of the device.
The last one is a delta fan, and it is more like an axial fan but comes in a boxed frame. That's why it is most commonly used in areas where good airflow is required, along with structural integrity and reliability.
The frame securely holds everything into place, including the motor and blade. These small fans can operate at high levels providing optimal cooling performance.
DC Blowers come in different forms factors. Some have ample surface area to throw air in their front while some perpendicularly throw air. So, when you look for a blower for your project, check which one offers the best ventilation for good cooling performance.
