The complete machine components of the ventilator include tunnel joints, a collector, a primary fan, a secondary fan, a diffuser, a round-to-square transition piece, a silencer box, and a diffusion tower, among others. Inside the fan, the airflow passages are uniformly smooth. The collector, rectifier, and fish-shaped tubes are all manufactured using cold-rolling molds. Meanwhile, the fish-shaped heat dissipation tubes and the motor base support plates not only meet stringent mechanical requirements such as adequate strength and rigidity but also incorporate features like rounded arc transitions to minimize drag. These design measures ensure that the fan’s airflow passages remain uniform and smooth, reducing flow resistance and significantly enhancing overall fan performance.
