A plurality of the heat exchanger pipes 3 are arranged in a horizontal direction, and stacked in an upward and downward direction, so as to form a heat exchanger pipe unit 4. A plurality of the units 4 are arranged in a horizontal direction at predetermined intervals, and both ends of the pipe 3 are jointed with a pipe plate 2 or a header for in-pipe fluid. A plate-like fin 12 is installed at the bottom of the pipes 3 in a manner that it is almost brought into close contact with the top face of the pipe 3 arranged at a lower stage of the pipes 3. The outer surface of the pipe 3 had better to be applied with a hydrophilic treatment for improving wettability.
