ABSTRACT:
A heat exchange apparatus comprising a heat transfer member; and at least one projecting blade which is arranged to confront the heat transfer member, and which carries out relative motion with respect to the heat transfer member; wherein a distance between the edge of the projecting blade at the side of the heat transfer member and a heat transfer surface of the heat transfer member is smaller than a value which corresponds to a rising point where an upward gradient of convective heat transfer coefficients rises as the distance decreases.
