ABSTRACT:
A fin-tube heat exchanger including thin plates, tubes penetrating though the thin plates, and one or more projections formed on the thin plates to resist the flow of air exchanged passing between the thin plates with which heat is to be exchanged is disclosed. The cross-sectional shape of each projection varies in its extending direction. The resistance against the flow of the passing air varies at each projection due to the variation of the cross-section of the projection, to change the flow direction of the heat exchanged air without the provision of an external guide means disposed near the exit of the heat exchanger. Therefore, the mechanism around the heat exchanger is simplified, and the entire size of a heating or cooling showcase unit having the heat exchanger is reduced.
