The difference between SanAce DC cooling fan and axial cooling fan-Capital-Cooling fan manufacturer

The cooling fan can be divided into many types based on its air supply form, such as axial flow, DC, centrifugal, etc. According to its different forms of electricity consumption, it can be further divided into DC and AC. What exactly is a DC cooling fan, and what are the differences between a DC cooling fan and an axial cooling fan?

Simply put, a DC cooling fan converts electrical energy into mechanical energy through DC voltage and electromagnetic induction, thereby driving the rotation of the fan blades to achieve the purpose of heat dissipation. The DC cooling fan is operated using a DC power supply! The voltage of the DC power supply used must be consistent with the working voltage indicated on the fan. A battery is a DC power source. If it is used to drive a DC fan, in addition to charging, it is also necessary to check whether the voltage of the battery is consistent with the working voltage of the fan. If it is not consistent, a DC/DC converter should be used to change the voltage to be consistent.

The principle of the operation of a DC cooling fan is based on the right-hand rule of the ampere. When a conductor passes through an electric current, a magnetic field is generated around it. If this conductor is placed in another fixed magnetic field, it will generate suction or repulsion, causing the object to move. A rubber magnet pre filled with magnetism is attached inside the blades of the DC cooling fan. Surrounding the silicon steel sheet, two sets of coils are wound around the axis, and Hall sensing components are used as synchronous detection devices to control a set of circuits that rotate the two sets of coils wound around the axis.

The speed measurement signal of a DC cooling fan is generally output from a three lead plug. The yellow and black wires in the three leads are the+12V power supply and ground, respectively. The other color of the wire is the speed signal output wire. It should be noted that the third lead of some three lead DC cooling fans is not a speed measurement signal output line, but a speed control signal line, which inputs a speed control signal to the DC fan motor. So far, there are two types of monitoring methods for the fan itself: alarm sensors and speed sensors. The alarm sensor can provide an alarm signal when the fan speed is below a certain threshold value, and the speed signal output can achieve real-time monitoring of the fan speed.

And axial flow cooling fan, also known as axial flow fan. Mainly suitable for exhaust in places such as dust and gravel yards; Medium sized axial fans are mainly suitable for indoor ventilation and heat dissipation, such as grain silos; Small axial fans are mainly suitable for ventilation and heat dissipation of mechanical equipment, such as electrical cabinets. When an axial fan is in operation, the blades push the air to flow in the same direction as the shaft, so it is called an axial fan.
