<p>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of attaining a superior heat exchanging performance by preventing heat from being transmitted through plate fins between the adjoining two straight pipes of zig-zag heat exchanging pipes.SOLUTION: Plate fins 3 for a heat exchanger are fixed while riding over the adjoining two straight pipes 21A, 21B of a zig-zag heat exchanging pipe 2 at a heat exchanger 1. The fins have one end side fins 30A having holes 31A through which one straight pipe part 21A passes and the other end side fins 30B having holes 31B through which the other end straight pipe part 21B passes, and a cut-out part 32 for shutting off heat transmission is formed to divide both fins 30A, 30B except a connecting part 33.</p> |
