Product Details


Application: Cooling system and ventilation
Example: In the wind turbine generator cabin, AC centrifugal fans are used to cool the generator, gearbox and transformer and other equipment to ensure stable operation in high temperature environment. At the same time, fans are also used for ventilation of the cabin and tower to prevent equipment overheating.
Application: Photovoltaic module cooling and equipment ventilation
Example: In large photovoltaic power stations, AC centrifugal fans are used to cool photovoltaic modules to prevent efficiency loss caused by high temperature. In addition, fans are also used to dissipate heat from inverters and transformers to ensure that these devices work normally in high temperature environments.
Application: Battery cooling and environmental control
Example: In lithium-ion battery energy storage systems, AC centrifugal fans are used to cool battery packs to prevent battery overheating, extend service life and ensure safety. At the same time, fans are also used to maintain the temperature and humidity of the operating environment of energy storage equipment.


Application: Cooling of motors and drives
Example: In industrial robots, AC centrifugal fans are used to cool servo motors and drives to prevent them from overheating due to long-term operation. For example, in welding robots in automobile manufacturing plants, fans ensure that motors and drives work stably in high-temperature environments.
Application: Heat dissipation of electronic components
Example: In service robots used in hotels or hospitals, AC centrifugal fans are used to cool internal electronic control boards and power modules to prevent system failures caused by overheating. For example, fans in food delivery robots ensure that their electronic components maintain a suitable temperature during long-term operation.
Application: Equipment cooling and environmental control
Example: In surgical robots, AC centrifugal fans are used to cool high-power lasers and electronic control systems to ensure precise operation during surgery. For example, fans in the da Vinci surgical system are used to maintain equipment temperature to ensure safe surgery.


Application: Heat dissipation of server cabinets
Example: In AI servers and data centers, AC centrifugal fans are used to cool server cabinets to prevent overheating of CPUs, GPUs, and other high-power components. For example, Google data centers use centrifugal fans for efficient heat dissipation to ensure that servers remain stable during long-term high-load operation.
Application: Cooling of base station equipment
Example: In 5G and data base stations, AC centrifugal fans are used to cool base station equipment, such as RF modules and power supply equipment. For example, 5G base stations use centrifugal fans for heat dissipation to ensure stable operation of the equipment in high temperature environments.




2. Energy Saving: Since the fan operates within the high-efficiency range, it can reduce energy consumption, thereby lowering operational costs. This is a significant economic benefit for users who rely on the fan for long-term use.
3. Reliability: The smoothness of the performance curve indicates stable fan operation, reducing the likelihood of failures and the need for maintenance. This enhances the equipment's reliability and minimizes downtime and repair costs.
4. Wide Applicability: The fan can operate under different flow rate requirements, making it suitable for a variety of applications. Whether low or high flow rates are needed, the fan can provide the corresponding performance support.
5. Ease of Control: The clarity of the performance curve makes it easier to control and adjust the fan. Users can fine-tune the fan's operating state based on actual needs to achieve optimal results.
The fan can be designed &manufactured with customized request.
