ABSTRACT:
A finned tube heat exchanger is disclosed in which the structure thereof is simple, and the heat exchanging performance is increased. The heat exchanger has a plurality of fin plates arranged in parallel with one another, and a plurality of heat exchanger tubes extending through the fin plates. Each of the fin plates has a plurality of projected strips, and the strips include first to ninth rows of strips disposed in a parallel relationship. Each of the first and ninth rows of strips is formed of a trapezoidal strip and two parallelogrammic strips, each of the second to eighth rows of strips is a strip extending between openings disposed adjacent to one another in the longitudinal direction of the fin plate. The second to eighth rows of strips are disposed not to be spaced, and two sides of each of the second to eighth rows of strips provided with leg portions are curved to have the same curvature as that of the openings adjacent to the two sides.
