Claim Text:
1. A finned-tube heat transfer device comprising: a housing enclosing a first flow path in the circumferential direction with the first flow path penetrating the housing in the longitudinal direction of the housing, said housing having longitudinal ends comprising a first inlet for a first fluid and a first outlet for the first fluid, said first flow path being laterally delimited by two housing walls; and a tube system forming a second flow path for a second fluid, said tube system comprising a second inlet for the second fluid and a second outlet for the second fluid, said tube system being arranged in said first flow path and being coupled in said housing to said first flow path in a heat transferring manner and comprising a multitude of tubes, which are parallel to one another, which extend between said two housing walls and which are provided with fins within said first flow path, said tubes being arranged offset to one another transversely to a flow direction of the first fluid, said tubes being fluidically interconnected outside of said first flow path by a fluidic connection of said tubes effected within said two housing walls, said second fluid inlet being formed on one of said two housing walls and said one of the two housing walls comprising a hollow space comprising a distribution chamber, which fluidically connects entry ends of a plurality of said tubes to said second fluid inlet, said second fluid outlet being formed on another one of said two housing walls and said another one of said two housing walls comprises a hollow space comprising a collecting chamber, which fluidically connects exit ends of a plurality of said tubes to said second fluid outlet, one of said two housing walls comprising a first double wall structure, said first double wall structure comprising a first integrally formed one-piece inner wall and a first integrally formed one-piece outer wall, said first housing outer wall comprising a plurality of first connecting channel portions, said first connecting channel portions being diagonally arranged to form a diagonal arrangement of connecting channels, at least one of said plurality of first connecting channel portions being located at a spaced location from another one of said plurality of first connecting channel portions with respect to a first direction of said first housing outer wall, said at least one of said plurality of first connecting channel portions being located at a spaced location from yet another one of said plurality of first connecting channels portions with respect to a second direction of said first housing outer wall, said first direction being different from said second direction, said plurality of first connecting channel portions being integrally connected to said first integrally formed one-piece housing outer wall, another one of said two housing walls comprising a second double wall structure, said second double wall structure comprising a second integrally formed one-piece inner wall and a second integrally formed one-piece outer wall, said second integrally formed one piece outer wall comprising a plurality of second connecting channel portions, at least one of said plurality of second connecting channel portions being located at a spaced location from another one of said plurality of second connecting channel portions with respect to a second housing outer wall first direction of said second housing outer wall, said at least one of said plurality of second connecting channel portions being located at a spaced location from yet another one of said plurality of second connecting channels portions with respect to a second housing outer wall second direction of said second housing outer wall, said second housing outer wall second direction being different from said second housing outer wall first direction, said plurality of second connecting channel portions being integrally connected to said second integrally formed one-piece outer wall, each of said first connecting channel portions and each of said second connecting channel portions connecting an exit end of one of said tubes to an entry end of another one of said tubes, said second fluid inlet being formed on one of said first integrally formed one-piece outer wall and said second integrally formed one-piece outer wall, one of said first integrally formed one-piece outer wall and said second integrally formed one-piece outer wall and one of a portion of said first integrally formed one-piece inner wall and a portion of said second integrally formed one-piece inner wall defining said distribution chamber, another one of said first integrally formed one-piece outer wall and said second integrally formed one-piece outer wall and another one of said portion of said first integrally formed one-piece inner wall and said portion of said second integrally formed one-piece inner wall defining said collecting chamber, said second fluid outlet being formed on said another one of said first integrally formed one-piece outer wall and said second integrally formed one-piece outer wall.
