Aluminum Return Air Grille

- Mar 31, 2020-

Aluminum alloy air vents are used for air supply and return air in ventilation and air conditioning systems.They can be installed directly at the end of the pipe or on the ceiling or on the wall or door. With the rapid development of science and technology and industrial economy in recent years, The increasing demand for welded structural parts of alloy tuyeres has made the research on the weldability of aluminum alloy tuyeres deeper. The swirling tuyeres in aluminum alloy tuyeres use the rotation of the wind to send air in a spiral shape when working, resulting in a relatively high The induction ratio makes the supply air and the surrounding indoor air mix rapidly. Unlike the traditional diffuser, the air outlet grooves of the swirl air outlet are arranged radially, and the air supply in the air duct is guided by the air outlet grooves of the swirl air outlet, forming In the tangential jet, the supply air from the entire aluminum alloy tuyere generates a vortex like a typhoon under the action of multiple jets. The central area of the vortex forms a negative pressure zone, which induces the surrounding indoor air to quickly mix with the supply air. The entire supply air flow has a stable horizontal diffusion flow pattern. Its induction ratio is 10-20 times that of a conventional diffuser.
