THD Series

The THD series fan was inspired while observing a flying osprey. "The osprey's diving posture when catching prey is swift, quiet, and precise. Their wings work similarly to the principle behind how fans work too." Engineers manage to apply the posture and wing structures of ospreys to design fan blades via parameterized and simulated processes.

This THD series fan with bionic design manages to reduce up to 6dB-A of noise compared to its competitors while maintaining highly efficient operations. The measurement of noise is a logarithmic relation, so a reduction of 6dB-A is a 10^6 reduction of noise, which is equivalent to the difference between four fans running simultaneously and the noise from one fan- quite a significant margin.

Features & Benefits:

  • Multi-section stack design: using virtual simulation analysis and biometric parameters of a bird wing airfoil section
  • Stator blade tip design: lowers noise and wing tip vortex through reduced wing tip connection surface which simulates the floating wing tip of an osprey in flight
  • High-strength Bionic blades: our new fan blades are stronger and have been tested through simulation and destruction of speed tests
  • hDEC Control : advanced motor drive control to improve the fan motor drive efficiency
  • Through vibration simulations and different material bonding strength studies, Delta has enhanced the structural design of the fan's frame to gain higher natural frequency for improved vibration and resonance.
