NOISE ATTENUATION FAN - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240023271 titled 'NOISE ATTENUATION FAN
Simplified Explanation
The patent application describes a fan with multiple blades, where each blade has two surfaces with a blade surface profile. At least one surface of the blade includes a plurality of turbulators that define a portion of the blade surface profile. Each turbulator extends across the width of the blade and can delay airflow separation from the blade, increasing the laminar flow region and reducing noise.
- The fan has multiple blades with a blade surface profile.
- At least one surface of the blade has turbulators that define a portion of the blade surface profile.
- Each turbulator extends across the width of the blade.
- The turbulators can delay airflow separation from the blade.
- This increases the laminar flow region and reduces noise.
Potential Applications:
- HVAC systems
- Cooling fans for electronic devices
- Automotive cooling systems
Problems Solved:
- Airflow separation from the blade, which can cause noise and inefficiency.
Benefits:
- Reduced noise
- Improved efficiency
- Increased laminar flow region
Original Abstract Submitted
in one or more embodiments, one or more systems and/or one or more processes comprises a fan with a plurality of blades, with each blade extending radially outward from the central body to define a blade length, each blade having two surfaces, wherein each surface of the two surfaces has a blade surface profile, wherein at least one surface of the two surfaces comprises a plurality of turbulators that define a portion of the blade surface profile, and each turbulator of the plurality of turbulators extends at least a portion of a width of the blade. the turbulators may delay airflow separation from the blade to increase the laminar flow region and reduce noise.
