Abstract

The invention describes a method for producing a plate heat exchanger 1. Wavy profiled sheets 9 and separating sheets 10, together with sidebars 11, are stacked one above the other, provided with solder and soldered together in such a way that a block 2 is obtained. The block is closed off outwardly by means of the cover sheets 12. The contours of the intermediate pieces 3 are milled out at the respective positions 4 on the block 2 thus obtained. In a refinement of the invention, frames are used as intermediate pieces 3. The frames 3 are positioned in the milled-out portions at the positions 4, provided with solder and tacked on by means of spot welding. Subsequently, in a second step, the frames 3 are soldered onto the heat exchanger block 2. The headers 5a and 5b are in each case welded onto the frames 3.
