ABSTRACT:
Heat exchange apparatus including a tube having inward projections or turbulating structure extending into the tube at substantially all angular locations around the diameter of the tube except along a drainage path extending along the entire bottom inner surface of the tube. The width of the drainage path is sufficient to ensure that fluid may fully drain from the tube. No turbulating structure is positioned within the drainage path so as to prevent fluid from draining from the tube and potentially contaminating the tube. The turbulating structure of the invention are dimples which are deformed into the tube and have smoothly sloping side walls which further inhibit the dimples from preventing full drainage of the tube. The tubes are fixed to the apparatus at an angle which provides a drainage slope.
