Abstract:
A method for manufacturing a heat exchanger includes stacking a plurality of parting sheets, a plurality of lengthwise closure bars, and a plurality of widthwise closure bars to form a rectangular first heat exchanger section. The first heat exchanger section includes at least one widthwise passage extending between a pair of the widthwise closure bars and at least one lengthwise passage extending between a pair of the lengthwise closure bars. The method also includes brazing the rectangular first heat exchanger section together and cutting a first side and a second side of the rectangular first heat exchanger section to give the first heat exchanger section a tapered-trapezoid profile. The method further includes brazing an end of a second heat exchanger section to the first or second side of the first heat exchanger section.

Claim (Index 5):
A heat exchanger comprising:\n a first section comprising: a top opposite a bottom; a lengthwise dimension transverse to a widthwise dimension; a first parting sheet at the top of the first section; a first lengthwise closure bar and a second lengthwise closure bar under the first parting sheet, wherein the first and second lengthwise closure bars extend in the lengthwise dimension and are spaced from each other in the widthwise dimension; a second parting sheet under the first and second lengthwise closure bars, wherein the first parting sheet, the second parting sheet, the first lengthwise closure bar, and the second lengthwise closure bar together form a first lengthwise passage that extends in the lengthwise dimension through the first section of the heat exchanger; a first widthwise closure bar and a second widthwise closure bar under the second parting sheet, wherein the first and second widthwise closure bars extend in the widthwise dimension and are spaced from each other in the lengthwise dimension; a third parting sheet under the first and second widthwise closure bars, wherein the second parting sheet, the third parting sheet, the first widthwise closure bar, and the second widthwise closure bar together form a first widthwise passage that extends in the widthwise dimension through the first section of the heat exchanger; a third lengthwise closure bar and a fourth lengthwise closure bar under the third parting sheet, wherein the third and fourth lengthwise closure bars extend in the lengthwise dimension and are spaced from each other in the widthwise dimension; and a fourth parting sheet under the third and fourth lengthwise closure bars, wherein the third parting sheet, the fourth parting sheet, the third lengthwise closure bar, and the fourth lengthwise closure bar together form a second lengthwise passage that extends in the lengthwise dimension through the first section of the heat exchanger, wherein the first and second lengthwise closure bars are both longer than the third and fourth lengthwise closure bars.
