According to the flow direction of the air flow in and out of the cooling fan, it can be divided into the following categories: axial flow fan, centrifugal fan, mixed flow fan, cross flow fan, blower, and then it can be divided into DC cooling fan and AC cooling fan according to its different power supply form.
So today we focus on the discussion of axial fan and DC
Cooling fanThe differences and differences between the two.
First, when the axial flow fan is running, the blades push the air to flow along the axis. The axial flow fan is usually installed on the cabinet of the electrical equipment, and sometimes integrated on the motor. Due to the compact structure of the axial flow fan, it can save a lot of space and is easy to install.Therefore, it is widely used.
The DC cooling fan is a rotating machine that converts electrical energy into mechanical energy. Its operating principle is based on Ampere's right-hand rule. If the conductor passes current, a magnetic field will be generated around it. If the conductor is placed in another fixed magnetic field, suction or repulsion will be generated.,Moving objects. Inside the fan blade of the DC fan, a rubber magnet filled with magnetism is attached in advance. Around the silicon steel sheet, the axis part is wound with two sets of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits.Make the two sets of coils wound around the axis work in turn. The silicon steel sheet produces different magnetic poles, which generate attraction and repulsion with the rubber magnet. When the suction repulsion is greater than the static friction of the fan, the fan blades naturally rotate. Since the Hall sensing component provides a synchronization signal, the fan bladeTherefore, it can continue to operate.
DC cooling fan can only be operated by DC power supply, and the voltage used must be consistent with the rated voltage of DC cooling fan. Axial flow fan covers AC cooling fan and DC DC cooling fan, both of which are inclusive,Closely related.
