An outdoor unit for an air conditioner is disclosed, the outdoor unit characterized by: a case () formed with an air suction port () sucking air from outside and an air discharge port () discharging the sucked air; a first blowing fan () formed inside the case () for discharging the air sucked from the air suction port () to the air discharge port (); and a second blowing fan () formed inside the case () and positioned on the same axis of the first blowing fan () for rotating in an opposite direction of the first blowing fan (), such that generation of cavitation of a blowing fan is limited to greatly reduce noise and vibration.

Outdoor unit for air conditioner

An outdoor fan for an air-conditioner is provided to reduce unnecessary energy consumption and noise generated during an operation by reducing a side circulation flow generated when the fan rotates. The outdoor fan may include a hub shaft with a side hole, and rotary blades that convert rotary power received from the hub shaft into a pressure difference. The hub shaft may include a main plate unit perpendicular to the hub shaft and, positioned at a front side as compared to a virtual plane that includes the side hole, and the main plate unit to cover at least a portion of the hub shaft.
