Provided is a refrigeration device-use heat source unit configured so that, even if using a heat exchanger in which air is caused to pass through a plurality of surfaces thereof, the unit is capable of supplying different surfaces of the heat exchanger with cooling air obtained by water that is sprayed from at least one sprayer. The present invention is an outdoor unit (2) of an air conditioner (1), the outdoor unit (2) being provided with: an outdoor heat exchanger (14); an outdoor fan (15); a wind tunnel (8); and a two-fluid sprayer (6) that sprays water drops inside the wind tunnel (8). A rear surface-side extension section (80) of the wind tunnel (8) extends to the rear surface side of the outdoor heat exchanger (14). A front surface-side extension section (70) of the wind tunnel (8) is continuous at the front surface side of the rear surface-side extension section (80), and widens while securing gaps farther outside of parts which constitute left-right side surface parts of the outdoor heat exchanger (14). |
