摘要

Tanks (25,27) of a first heat exchanger (21) have plane sections (39) perpendicular to bottoms (41,45) having a plurality of tube insertion holes (49,51) formed therein. Tanks (31,33) of a second heat exchanger (23) with circular cross sections have bottoms (43,47) having a plurality of tube insertion holes (53,55) formed therein. The axes of the tube insertion holes (49,51,53,55) of the first (21) and second (23) heat exchangers are held in parallel with each other. The second heat exchanger (23) is in contact with the plane sections (39) of the first heat exchanger tank (25,27).
