Abstract:
1. A heat exchanger comprising: first and second bars respectively extending in first and second directions transverse to one another to form a skeleton, at least some of the first bars forming a side with gaps between the first bars; a core including cooling fins arranged within the skeleton, wherein the cooling fins include a set of cold fins and a set of hot fins arranged transverse to one another; parting sheets arranged between the cooling fins; blocking bars extending in the first direction a length and arranged within the gaps between the at least some of the first bars, the blocking bars including first and second widths each less than the length, the at least some of the first bars and lengths of the blocking bars forming a blocking surface diverting flow around a portion of the core for reducing thermal stress in an area of the portion; and a header surrounding a portion of the side and in fluid communication with the gaps, wherein the blocking surface is arranged proximate to a corner of the core within the header.
