Claim Text:
1. A heat exchanger flow balancing system, comprising: a first plenum having a first end, a second end opposite the first end, and a tube wall, wherein the first plenum extends between the first and second ends thereof along a first direction; a first transfer pipe communicating with the first plenum, wherein the first transfer pipe extends along a second direction orthogonal to the first direction; a second plenum spaced apart from the first plenum, the second plenum having a first end, a second end opposite the first end, and a tube wall, wherein the second plenum extends between the first and second ends thereof along the first direction; a second transfer pipe communicating with the second plenum, wherein the second transfer pipe extends along the second direction; a plurality of tubes extending between the tube wall of the first plenum and the tube wall of the second plenum, each of the tubes being of equal diameter to one another, the first plenum communicating with the second plenum by the plurality of tubes extending therebetween, wherein each said tube extends along a third direction orthogonal to the first and second directions; and a flow restriction disposed at a juncture of each of the tubes with the first plenum, where smallest diameter restrictions are located at a juncture nearest the first transfer pipe and at each juncture farthest from the first transfer pipe, where diameters of the flow restrictions of the remaining junctures of the remaining transfer pipes decreases from the restriction at the juncture nearest first transfer pipe to each of the junctures farthest from the first transfer pipe.
