220V Refrigerator Cross Flow Cooling Fan , 33150 Portable Heater Cross Fan

The cross-flow fan is mainly composed of impeller, duct and motor.
(1) The impeller is generally multi-blade forward blade type, but the two end faces are closed.
 
(2) There is no limit to the width b of the impeller, when the width is increased. Traffic also increased.
 
(3) Unlike the centrifugal fan, the tubular fan is opened on the side plate of the housing to make the air flow into the fan axially, but the housing is partially open to make the air flow directly radial into the fan. Air flow across the blade twice. Some tubular fans are equipped with a stationary guide vane at the inner edge of the impeller to improve the airflow condition.
 
(4) The air inlet and air outlet are rectangular, easy to cooperate with the building. The use of small tubular fans is steadily expanding.
 
Our product advantage
1, wind speed distribution is uniform
With little low disturbance, the outgoing wind is concentrated. In this way, it can carry the wind far in low noise conditions, and can easily change the direction of the wind flow.
 
2. The air flow in the outlet is evenly distributed along the axial direction
Especially when the axial width of the fan and fan impeller diameter ratio is large, this is difficult to achieve other types of fans.
