ABSTRACT:
A heat exchanger which, in one embodiment, includes an elongate tube having a plurality of straight tube segments and a plurality of bent tube segments to form a generally oval spiral configuration is described. The straight tube segments form opposite sides of the exchanger, and the straight tube segments are configured to be located substantially perpendicular to a direction of air flow. A space is formed between the exchanger opposite sides, and the cross-sectional area of the space between the exchanger opposite sides continuously decreases from a first end of the exchanger to a second end of the exchanger. An end straight tube segment substantially extends over, or substantially covers or closes, an opening between opposing tube segments at the exchanger second end. A plurality of heat exchange fins project outwardly from the elongate tube. Due to its general shape, the above described heat exchanger sometimes is referred to herein as a pyramid exchanger.
