摘要： PROBLEM TO BE SOLVED: To provide an air-conditioning outdoor unit capable of increasing a heat exchanger capacity while maintaining a conventional unit size and effectively using a ventilation area high in the speed of wind speed distribution. SOLUTION: The air-conditioning outdoor unit 1 includes: a body frame 30 having an air suction port 31 on the side face, an air blowout port 32 on the upper face and a bottom plate 7 on the bottom face; a compressor 10 and piping 11 installed on the bottom plate 7; an air blowing fan arranged at the upper side in the body frame 30; a first heat exchanger arranged in the air suction port 31 of the body frame 30; and a second heat exchanger arranged along the inner face of the first heat exchanger. Air sucked from the air suction port 31 by the drive of the air blowing fan is made to pass through the first heat exchanger and the second heat exchanger in this order, and then blown out upwardly from the air blowout port 32. The vertical dimension of the second heat exchanger is set shorter than that of the first heat exchanger, and the second heat exchanger is arranged in the upper position of the first heat exchanger.

摘要： PROBLEM TO BE SOLVED: To provide an outdoor unit having an improved efficiency of heat exchange, by improving a wind velocity distribution of gas passing a heat source side heat exchanger.SOLUTION: The heat exchanger 4 is arranged in the vicinity inside a housing 2. On the upper part of the heat exchanger 4, a flat heat transfer pipe 6 is inserted into a plate-like fin 5 while a gas flow direction downstream side of the pipe is tilted downward in a gravity direction by a given angle. In the lower part of the heat exchanger 4, the flat heat transfer pipe 6 is inserted into the plate-like fin 5 while a gas flow direction upstream side of the pipe is tilted downward in the gravity direction by a given angle. Consequently, the wind velocity distribution of the air passing the heat exchanger 4 is substantially evened up on all portions of the heat exchanger 4.
