  • Patent number: 11835065
    Abstract: A fan frame turbulence structure includes a frame body having a wind incoming side and a wind outgoing side respectively on two sides of the frame body. The frame body defines an airflow passage which passes through the frame body from the wind incoming side to the wind outgoing side. The wind incoming side has an inlet in communication with the airflow passage. The inlet has a breaking section between the wind incoming side and the passage inner wall. The breaking section includes densely distributed breaking units. The breaking units define therebetween gaps in communication with the airflow passage. The breaking units serve to break and fracture airflow sucked in from the wind incoming side, whereby part of the airflow passes through the gaps between the breaking units and is broken and fractured into multiple gap turbulences to flow into the air passage so as to lower the wideband noise.
