Abstract
The invention describes a method for producing a plate heat exchanger. Wavy profiled sheetsand separating sheets, together with sidebars, are stacked one above the other, provided with solder and soldered together in such a way that a blockis obtained. The block is closed off outwardly by means of the cover sheets. The contours of the intermediate piecesare milled out at the respective positionson the blockthus obtained. In a refinement of the invention, frames are used as intermediate pieces. The framesare positioned in the milled-out portions at the positions, provided with solder and tacked on by means of spot welding. Subsequently, in a second step, the framesare soldered onto the heat exchanger block. The headersandare in each case welded onto the frames
