PROBLEM TO BE SOLVED: To provide an outdoor unit of an air conditioner of which the noise is lowered by eliminating nonuniformity in an air-cutting sound generated by an air flow running through between a large number of fins of a heat exchanger. SOLUTION: In the heat exchanger D for the outdoor unit of the air conditioner, a large number of laminated fins 1 or 1' are so constituted that a space (pitch) thereof in the back part D1 where the flow velocity of air is made high by opposing a propeller fan E thereto is larger than the space (pitch) in the opposite lateral parts D2 where the flow velocity is low. |
