Abstract
A heat exchanger can be configured to utilize multiple sections of hardway fins that can be configured so that an upper first section of the fins can build up liquid head and a second lower section of the fins can be configured to distribute liquid in an even, or uniform, manner. The first section of fins can utilize a different type of hole arrangement than the second section of fins. For instance, the diameter or width of the holes in the first section may differ from the diameter or width of the holes of the second section. In addition (or as an alternative), fin frequency and/or spacing between immediately adjacent holes in the first section of fins may be different from the spacing between immediately adjacent holes in the second section of fins.
