| 摘要 |
The invention relates to a heat exchanger, in particular for a motor vehicle, having tubes and if appropriate corrugated fins through which a first, hot medium can flow and which are arranged between collecting boxes, and having at least one side part ( 1 ) which is arranged laterally between two collecting boxes, a second medium which flows around the tubes and if appropriate corrugated fins being colder than the first, hot medium during operation, the side part ( 1 ) absorbing at least some of the tensile stresses which act at least on the outermost tube as a result of different thermal expansions of the tubes and if appropriate corrugated fins, and the side part ( 1 ) having slots ( 2 ) and/or openings ( 4 ) which change the spring constant of the side part ( 1 ) in relation to a side part without slots and/or openings such that, in the event of a different longitudinal expansion of the central tubes relative to the outermost tube which is arranged adjacent to the side part ( 1 ), the tensile stress which acts on the outermost tube is reduced. |
