The principle of micro cooling fan

The working principle of the miniature cooling fan is realized by energy conversion, namely: electric energy → electromagnetic energy → mechanical energy → kinetic energy. The circuit principle is generally divided into various forms, and the performance of the fan will be different if the circuit used is different. u003cbru003e u003cbru003e u003cbru003e Classification and characteristics of cooling fans: Wenling Tongchi Automobile Air Conditioning Manufacturing Co., Ltd. has advanced mechanical equipment to produce miniature cooling fans u003cbru003e u003cbru003e u003cbru003e 1. Axial fan 　　 The blades of axial fan push air to flow in the same direction as the shaft. The impeller of an axial fan is similar to the propeller. When it works, most of the airflow is parallel to the shaft, in other words along the axis. When the inlet airflow is free air with zero static pressure, the axial flow fan has the lowest power consumption. When operating, the power consumption will increase as the airflow back pressure rises. Axial fans are usually installed in cabinets of electrical equipment, and sometimes integrated on motors. Because of their compact structure, they can save a lot of space and are easy to install, so they are widely used. u003cbru003e Features: high flow rate, medium wind pressure u003cbru003e2. Cooling fan 　　 When the cooling fan works, the blades push air to flow in a direction perpendicular to the axis (i.e. radial), the air intake is along the axis direction, and the air outlet is perpendicular to the axis direction. In most cases, the cooling effect can be achieved by using an axial fan. However, sometimes if the airflow needs to be rotated by 90 degrees or when a larger wind pressure is required, a cooling fan must be used. Strictly speaking, fans are also cooling fans. u003cbru003e u003cbru003e u003cbru003e Three: Hongchen Electronic Technology Co., Ltd. has advanced production equipment and testing equipment,
