The working principle of aluminum alloy louver tuyere: the rotating wind at work adopts the aluminum alloy louver tuyere, and the air is sent to the spiral to produce a high induction rate, which is quickly mixed with the surrounding indoor air. Different from the traditional diffuser air tank, the aluminum alloy tuyere outlets are arranged radially and form jets through the swirl tuyere guide grooves. The vent holes are air ducts for the wind blowing in the tangential direction under the action of multiple jets everywhere. The swirling group is like a typhoon. The central area of the negative pressure area formed by the vortex rapidly induces the mixing of the surrounding indoor air, and the diffusion of the air flow in a steady state is a horizontal flow state.
