| 摘要 |
The invention relates to a heat exchanger comprising a block, which has fins and pipes and which is arranged between two reservoirs, wherein each fin comprises several fin sections and each fin section is approximately V-shaped and the two flanks forming a fin section each have several air slits, which extend perpendicularly to the flow direction of a medium flowing through the fin section, wherein the two flanks of the fin section are connected by means of a first connecting surface and/or the flanks of two consecutive fin sections across from each other are connected by means of a second connecting surface, wherein the first connecting surface and/or the second connecting surface has a fin section cross-section variation element, which is directed into the intermediate space between the flanks forming a fin section and/or the flanks of two consecutive fin sections that are across from each other. |
