<p>An evaporator 1 comprises a plurality of flat heat exchange tubes 12 arranged in a left-right direction at a spacing with the widthwise direction thereof pointing forward or rearward, and fins 14 arranged between respective adjacent pairs of heat exchange tubes 12. The fins 14 have at least front edges thereof projected forwardly outward beyond the heat exchange tubes 12. Assuming that the amount of projection of the fins 14 beyond the heat exchange tubes 12 is X mm and that the heat exchange tubes 12 are Y mm in thickness in the left-right direction, i.e., in height, X and Y have the relationship of 0.11Y=X=1.0Y. The surfaces of the fins 14 can be drained of condensation water efficiently.</p> |
