Heat exchanger

Abstract

Abstract PURPOSE:To make the width of corrugated fins in a heat exchanger uniform, by disposing groups of tubes slided off from each other at some rate to the pitch of a tube, and by interposing corrugated fins for one row to each row of tubes. CONSTITUTION:A group of tubes 11 and 12 at each row is disposed in a unit of row, slided off from each other at an arbitrary distance, a half distance to the pitch of a tube, for instance, to the direction at right angle to the air flow X. Corrugated fins 13, corresponding to the width (d) of tubes for one row, in the same form, are respectively provided between each flat tubes (11a, 11a), (12a, 12a) of each group of tubes 11 and 12 as mentioned above, thermally bound to the tubes. With such an arrangement, the width of a corrugated fin can be made uniform.
