Method for manufacturing a laminated heat exchanger and laminated heat exchanger

摘要

The method involves providing a layer block (1) formed from layer sheets (3, 4), which have a boundary region (5) bent around 180 degrees, where the boundary region (5) is in material connection with another boundary region (6), which is bent around 180 degrees, of an adjacent layer sheet. A solder foil strip (16) is fixed or glued on the region (6) of the sheets (4) which is bent, before the boundary region (6) is soldered with the boundary region (5) of the neighboring layer sheet (3). Each bent boundary region of the sheet is provided on both sides with a solderable coating. Independent claims are also included for the following: (1) a soldering layer heat-exchanger with a layer block formed from layers sheets (2) a soldering component with a soldered gap between two connecting regions for a material-connection close confinement of a chamber or a channel.
