[Know about Heat Dissipation] Introduction of DC Brushless Heat Dissipation Fan

Release time:

2019-07-17

The structure of the DC brushless cooling fan: it can be divided into four main parts: rotor, stator, outer frame, motor (motor) and some other fragmentary parts. First, the fan rotor part: including fan blades, which are the core of generating air flow and the axis of the cooling fan. It is used to support the rolling of the balanced fan blades, the rotor magnetic ring, the permanent magnet, the key to switch the speed of the propulsion magnetic stage, the outer frame, and the fixed magnetic ring, fan stator part: including supporting springs, separating bearings to balance axes and bearings, providing high speed, low friction, long-life rotation, retaining rings, fixing nodules to rotate the entire component, motor part, production rotation direction, energy

DC brushlessCooling fan Structure: It can be divided into four main parts: rotor, stator, outer frame, motor (motor) and some other fragmentary parts
First, the fan rotor part:
Including fan blades, which are the core of generating air flow and the axis of the cooling fan, used to support the rolling of the balanced fan blades, the rotor magnetic ring, the permanent magnet, the key to the switching speed of the propulsion magnetic stage, the outer frame of the magnetic ring, and the fixed magnetic ring
Second, the fan stator part:
Including supporting springs, separating bearings to balance axes and bearings, providing high speed, low friction, long-life rotation, retaining rings, fixed nodules to rotate the entire component, motor part, production rotation direction, active size, rotation speed key
Third, the cooling fan frame:
Support the fan motor and guide the flow;
Fourth, the fan motor part
Including circuit board, control energy consumption and signal access, silicon steel sheet (I. e. stator magnet, with winding coil attached) to produce magnetic stage propulsion switching, silicon steel sheet upper and lower cover, fixed and insulator.
classification of dc brushless cooling fan:
According to the different bearings, it can be divided into four types: 1. Single ball bearing brushless fan, 2. Laifu bearing brushless fan, 3. Hydraulic bearing brushless fan, 4. Nano bearing brushless fan. The specifications and sizes of DC brushless fans are generally 6cm, 7cm, 8cm and 9cm. A few radiators begin to use 12cm super-large diameter fans. The sizes and regulations of fans are usually marked with four digits.
The above is about the structure and classification of DC brushless cooling fans. Shenzhen Jiangshanlai Electronic Technology Co., Ltd. is a large-scale enterprise specializing in the customization, research and development, manufacturing, sales and service of DC brushless motors, DC cooling fans, DC brushless fans, DC bracket fans, pressurized cooling fans, miniature cooling fans, DC cooling fans, DC blowers, and non-standard fans, and DC fan wholesale manufacturers, DC fan supplier.
