A heat exchanger apparatus can be configured so that there is at least one 'U' or “C” shape configured manifold in combination with at least one “Z” or “S” shape configured manifold for the heat exchanger apparatus for the input and output of fluid into and out of the heat exchangers of the heat exchanger apparatus. In some embodiments, downstream and/or upstream lines can be connected to the manifolds at a center or off-center point for conveying inlet fluid and outlet fluid. A method of retrofitting a pre-existing plant, building a new plant, or designing a new plant that utilizes an embodiment of the heat exchanger apparatus can help provide an improved heat exchanger arrangement without significantly increasing the footprint needed for the arrangement so that a plant can be improved with an embodiment of the apparatus without requiring an enlarged footprint for the plant.

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.
