Product Name:4020 Ball DC Fans
4020 Ball DC Fan is a product of Shenzhen Huaxinrong Plastic Electronics, which adopts pure copper DC brushless motor and PBT frame blades, and has the functions of operation monitoring, stopping alarm, PWM speed regulation, reverse connection protection, automatic restart, and waterproof, etc. The fan size is 40x40x20MM, and the airflow is 568CFM. The fan size is 40x40x20MM, speed is 5000-14000RPM, airflow is 568CFM, pressure is 345mmAq, noise is 226dBA, voltage is 05V-24V, weight is 26g. the fan consists of four parts: rotor, stator, motor and frame, the core components are stator and rotor. The principle of operation is to attach a first charged with magnetic rubber magnet around the silicon steel sheet, the shaft part of the winding two groups of coils, and the use of Hall induction components as a synchronous detection device to control a set of circuits, so that the two groups of coils wrapped around the core of the shaft to take turns to work, resulting in a different magnetic poles, and the rubber magnet generates suction and repulsion, thus making the fan blade rotation.
Ball DC fan is a highly efficient cooling device with ball bearing structure, which can provide good ventilation with low noise. DC fan consists of rotor, stator, outer frame, motor (motor) and other main parts and ball bearings, the core components are stator and rotor, through the magnetic field to generate suction or repulsion to drive the fan blades to rotate. Fan size size is generally expressed in terms of fan outer edge length and product thickness size, rated voltage is commonly 5V, 12V, 24V, 48V, etc., the degree of fan speed speed is expressed in rpm, the size of the air volume is expressed in Cubic Feet per Minute (CFM) or Cubic Metres per Minute (CMM), the size of the air pressure is expressed in mm-H2O or inH2O, and the size of the noise value is expressed in dBA.
Advantages of ball DC fans include:
1. Efficient heat dissipation: ball DC fans can provide high airflow and low noise, which can effectively take heat away from the equipment and keep it running normally.
2. long life: high quality ball DC fan, such as DC4020 ball fan produced by Huaxinrong Plastic & Electronics Co., Ltd, has a life span of up to 60,000 hours, and can operate stably for a long time.
3. Low Maintenance Costs: Ball DC fans have low maintenance costs and only require regular cleaning and lubrication.
4. Wide range of applications: Ball DC fans are suitable for a wide range of equipment and applications, such as computers, servers, electronic equipment, automobiles, and so on.
Overall, the ball DC fan is a highly efficient, long-life, low-maintenance cooling device that is widely used in a variety of devices and applications.
