Abstract:
1. A heat exchanger comprising: a plurality of tube-like first members having respective first inlet and first outlet distal end portions defining respective first inlet and first outlet openings, said first members being spaced-apart from one another so that a series of elongate gaps are formed between the first members, said first members forming a plurality of first passageways for flow of a first fluid in heat exchange relationship with cooling air flowing through said gaps during use of said heat exchanger, said first members and said elongate gaps forming a primary heat exchange area having a length extending at least most of the length of one of the first members and a width equal to the total of the heights of said first members and the widths of said gaps; opposed inlet and outlet manifold members connected respectively to said first inlet and outlet distal end portions, said inlet manifold being adapted to receive said first fluid and conduct said first fluid to said first inlet openings, said outlet manifold being adapted to receive the first fluid which has been cooled by said cooling air; a plurality of tube-like second members arranged in a row and having end portions defining second inlet and second outlet openings, all of said second inlet openings being joined and all of said second outlet openings being joined so as to form respectively a second inlet manifold and a second outlet manifold, said second inlet manifold being adapted to receive a liquid coolant and conduct said liquid coolant to a plurality of second passageways formed by said second members, said second outlet manifold being adapted to receive said liquid coolant from said second passageways; said second members including two outer second members located at opposite ends of the row and intermediate second members located between said outer second members, at least said intermediate second members each extending into a respective one of said elongate gaps for heat exchange between said first fluid and said liquid coolant, wherein said second members fill a portion only of said gaps, said portion extending over a secondary heat exchange area which is part of said primary heat exchange area.
