Abstract
The invention relates to an axial flow fan for condenser in a refrigerator for enhancing efficiency and lowering noise, in which the number of blades is three, the diameter of a hub is 23.3±5% of the outside diameter of the axial flow fan and the width of each of the blades is 36.6±3% of the outside diameter of the axial flow fan.
Claims8
An axial flow fan for a condenser in a refrigerator, the axial flow fan comprising:
- a hub;
- and
- three blades, wherein the diameter of the hub is 23.3±5% of an outside diameter of the axial flow fan and the a width of each of the blades is 36.6±3% of the outside diameter of the axial flow fan;
- and each of said blades has a maximum camber position of 0.65 which is uniformly distributed from the hub to a blade tip, wherein the maximum camber has curved distributions of 4.0 to 5.0% from the hub to the maximum camber position and of 5.0 to 6.0% from the maximum camber position to the blade tip.
