Applications

1.Electronic Equipment Cooling:

1. 1. Servers and Network Equipment: Server cabinets, routers, switches, and other network equipment have limited internal space but require strong heat dissipation capabilities to maintain stable operation. The high airflow and high static pressure of this fan can effectively exhaust heat and ensure equipment performance.
   2. Industrial PCs and Embedded Systems: Industrial control computers and embedded systems often need to work for long periods in harsh environments with high heat dissipation requirements. The reliability and environmental adaptability of this fan make it an ideal choice.
   3. Desktop Computers and Gaming Consoles: Used for cooling major heat-generating components such as CPUs and graphics cards, especially suitable for compact chassis or gaming consoles with high cooling requirements.
   4. Power Supplies: Efficient power supplies also require good heat dissipation internally. This fan can help reduce power supply temperature and extend its lifespan.
   5. LED Lighting Equipment: High-power LED lamps generate a lot of heat during operation. This fan can be used for heat dissipation to ensure the brightness and lifespan of LED lamps.

2.Industrial Equipment Ventilation and Cooling:

• 1. Automation Equipment: Various control cabinets and drives on automated production lines require a good heat dissipation environment to ensure stable equipment operation.
  2. Welding Equipment: A large amount of heat is generated during welding. This fan can be used for ventilation and cooling of welding machines or welding work areas.
  3. Frequency Converters and Drives: Frequency converters and drives used for motor control also generate heat during operation, requiring effective heat dissipation.
  4. CNC Machine Tools: CNC machine tools generate heat during high-speed operation, affecting machining accuracy and tool life. This fan can be used for cooling the machine tools.

3.Household Appliances:

• 1. Air Purifiers and Fresh Air Systems: Although this fan has a relatively high noise level, it can still be used in some air purifiers or fresh air systems with high airflow requirements to promote air circulation and filtration.
  2. Humidifiers and Dehumidifiers: Used to promote air flow and improve humidification or dehumidification efficiency.
  3. Electric Heaters and Warmers: Used for auxiliary heat dissipation to improve heating effect.

4.More Specific Examples:

1. Server Cabinets: Can be installed on the top or side of the cabinet to exhaust the hot air generated by the servers.
2. 3D Printers: Used for cooling the print head or stepper motors to ensure printing quality and stability.
3. Projectors: Used for cooling the bulb and circuit board to extend the projector’s lifespan.
4. Medical Equipment: Some small medical devices, such as portable medical testing instruments, may need to use this size of fan for heat dissipation.
