• Interpretation of key parameters

 

（1） Rated voltage

The rated voltage of the 4114NHH small fan is 24V. This low voltage design not only ensures safety during use and reduces the risk of electric shock, but is particularly suitable for environments with high requirements for electrical safety, such as homes, schools, and laboratories. At the same time, low-voltage operation also helps to reduce energy consumption, which is in line with the current trend of energy conservation and environmental protection. Long term use can save users considerable electricity costs.

 

（2） Size specifications

The size of the fan is 11911938 millimeters, and this compact design gives it excellent space adaptability. In the context of the continuous development of miniaturization and integration in electronic devices today, the 4114NHH small fan can easily adapt to various small spaces. Whether installed inside computer cases, small server cabinets, or other devices with strict space requirements, it will not occupy too much valuable space, providing greater flexibility for the overall design of the device.

 

（3） Maximum pressure

Its maximum pressure can reach 355Pa, indicating that the fan has a strong ability to overcome resistance. In some application scenarios where the ventilation duct is long, there are many bends, or significant resistance needs to be overcome, the 4114NHH small fan can ensure smooth air flow through the duct with its high pressure output, achieving effective ventilation effect. For example, in the ventilation system of some industrial equipment, even if there is a certain resistance in the pipeline, the fan can ensure the normal circulation of air.

 

（4） Input power

The input power is thirteen watts, and combined with its high pressure output and high speed characteristics, the 4114NHH small fan exhibits high energy utilization efficiency. While ensuring good ventilation performance, lower input power means significant energy savings and reduced operating costs during long-term operation. This has significant economic implications for places or equipment that require continuous ventilation.

 

（5） Rotational speed

The fan speed can reach up to 5000rpm, and high speed is one of the key factors in achieving high pressure output. The rapidly rotating fan blades can accelerate the flow of air, allowing the air to gain greater kinetic energy when passing through the fan, thereby generating higher pressure. However, high speeds may also bring some challenges, such as noise issues, but ebm-papst effectively solves this contradiction through advanced design and manufacturing processes.

 

（6） Noise level

The noise level is 60dB, which is well controlled among high-speed fans of the same type. Although the fan speed is high, the noise generated during operation has been effectively reduced by optimizing the fan blade design, using low-noise motors, and implementing good shock absorption measures. This allows the fan to function normally in environments with certain noise requirements, without causing significant interference to the surrounding environment.

 

• Analysis of unique characteristics

 

（1） Advanced aerodynamic design

The 4114NHH small fan adopts advanced aerodynamic design concepts. The shape of the fan blades has been carefully optimized, and their unique curves and angles can minimize air resistance and improve air flow efficiency when rotating at high speeds. This design allows air to accelerate more smoothly through the fan blades, resulting in higher pressure. Meanwhile, the optimized fan blade design can effectively reduce the generation of air turbulence, minimize the formation of noise, and further enhance the performance and user experience of the fan.

 

（2） High quality motor technology

The fan is equipped with a high-quality motor, which is the core guarantee for its stable operation and efficient performance. The motor adopts advanced permanent magnet technology, which has the characteristics of high efficiency and low energy consumption, and can more effectively convert electrical energy into mechanical energy to drive the high-speed rotation of the fan blades. The bearings of the motor are made of high-quality materials and precision manufacturing processes, which can withstand the frictional and impact forces generated during high-speed rotation, ensuring the stability and reliability of the fan during long-term operation. In addition, the motor also has good heat dissipation performance, which can timely dissipate the heat generated during operation and extend the service life of the motor.

 

（3） Reliable protective design

Considering the usage requirements of fans in different environments, the 4114NHH small fan has a reliable protective design. The casing of the fan is made of sturdy and durable engineering plastic material, which has good impact resistance and corrosion resistance, and can effectively protect the internal motor and fan blades from external object impact and chemical erosion. There is also a protective net on the shell to prevent foreign objects from entering the interior of the fan, avoiding damage to the fan blades and motor, and improving the safety of use.

 

（4） Good compatibility

The 4114NHH small fan has good compatibility and can seamlessly integrate with various devices and systems. It can be used in conjunction with heat dissipation components such as heat sinks and heat pipes to improve heat dissipation efficiency; It can also be connected to intelligent control systems to achieve automated operation and regulation (please contact customer service for specific functions of this product). For example, in some smart devices, fans can automatically adjust their speed based on the device's operating status, achieving more precise ventilation control.
