What are the distinctive features of a counter rotating fan?

Front Blade:

Responsible for initial acceleration and airflow guidance.

The direction of its rotation determines the initial kinetic energy and direction of the flow.

Rear Blade:

Rotates in the opposite direction relative to the front blade,

resulting in further compression and acceleration of the airflow. The reverse rotation optimizes hydrodynamic efficiency by eliminating the vortex generated by the front blade.

Dual Optimization:

The coordinated design of the front and rear blades enables higher static pressure and greater air volume output within a confined space while reducing turbulence noise

Technical characteristics
High static pressure
The structural design of the double-inversion Fan enables it to produce a much higher static pressure than the traditional single-layer fan, and is suitable for high-resistance heat dissipation environments, such as high-density heat sinks and long-channel heat dissipation scenarios.
High air volume
Through the collaborative work of the double-layer blades, the overall air flow efficiency is improved, so that it can provide more efficient heat dissipation for the equipment.
Low noise
The reverse rotation design reduces the turbulent component of the airflow and effectively reduces the noise level during fan operation. Compact structure
In the case of volume limitation, the double inversion fan can achieve the effect of two fans in series, which is especially suitable for application scenarios where space is limited but heat dissipation requirements are high.
Application field
Servers and data centers
In high performance computing, due to the high density of the device, the double inversion fan can provide excellent heat dissipation performance to ensure the stable operation of the device.
Industrial equipment
For high temperature or heat dissipation requirements of the equipment, such as frequency converter, laser equipment, etc.
Communication base station
Base station equipment usually needs to run continuously for a long time, and dual inversion fans can save energy and reduce noise while ensuring heat dissipation.
Sum up
The Dual reverse fan takes airflow performance and static pressure to new heights with an innovative counter-rotating blade design, providing the ideal solution for equipment with high heat dissipation requirements. In the increasingly important heat dissipation technology today, the application prospect of this fan in various fields is very broad.
