Abstract
A radiator (10) has tubes (14) and fins (15). The fins (15) have louvered sections (30) laterally aligned with a layer (20), and louvered sections (40), (42), and (46) misaligned from the layers. The louvered sections (40) and (42) are spaced from the louvered sections (30) to form a plain non-louvered section (44) therebetween.
Claims14
A heat exchanger characterized by:
- a plurality of layers of tubes with each layer having a plurality of tubes spaced from each other and with each layer spaced from each other to form a gap therebetween;
- a corrugated strip forming a plurality fins arranged between adjacent pairs of tubes within each layer of tubes;
- said fins having a first series of louvered sections laterally aligned with the tubes of each layer;
- said fins having a second series of louvered sections interposed between adjacent sections of the first series of louvered sections, each louvered section of said second series being laterally aligned with said gap between each layer and being spaced from adjacent sets of said first series to form plain non-louvered sections being interposed between said first and second series of louvers.

A heat exchanger characterized by:
- at least one layer of tubes having a plurality of tubes being spaced from each other;
- a folded strip forming a plurality fins arranged between adjacent pairs of tubes within said at least one layer of tubes;
- said fins having at least one louvered section laterally aligned with the tubes of at least one layer;
- said fins having at least one louvered section being laterally misaligned with each layer of tubes and being spaced from said laterally aligned louvered section to form a plain non-louvered section interposed between said aligned and misaligned louvered sections.
