ABSTRACT:
A tube/fin block for a heat exchanger has several tubes through which a heat transfer fluid can flow arranged side-by-side along a transverse direction of the block. Corrugated-fin complexes are inserted between respective adjacent tubes and are connected with the adjacent tubes. At least one of the corrugated fin-complexes is a double corrugated-fin complex with two corrugated-fin units arranged side-by-side in the transverse direction of the block. A particular manufacturing process for the tube/fin block is utilized. A heat insulation device is provided between the two corrugated fin units. A non-solderable spacer plate can be inserted between the two corrugated fin units and pulled out after the tube/fin block is soldered together so that a heat-insulating gap is formed. A plastic strip can be inserted into the heat-insulating gap as required. The block is appropriate for use, for example, in condensers and evaporators of motor vehicle air conditioners.
