Abstract:
1. A heat exchanger comprising: a pair of spaced manifold structures, and a plurality of heat transfer tubes extending between said manifold structures in generally parallel relationship with each other and being in fluid communication with said manifold structures, each of said heat transfer tubes having a plurality of parallel channels spaced from each other, and said heat transfer tubes being inserted in openings in said manifold structures, said heat transfer tubes being secured to said manifold structures by an initially fluent and then solidifying securing material, and there being modifications to at least one of said manifold structures and said heat transfer tubes to minimize the likelihood of said securing material at least partially blocking any of said plurality of channels; and a working fluid to flow inside said heat transfer tubes is one of a refrigerant, air, water, glycol solution, oil, air, nitrogen, helium, petrochemical gas and combination thereof.
