A method and an apparatus for producing a block for a plate heat exchange is described wherein partition plates and heat-conducting structures are stacked together with brazing material in a block, and the block is subjected to a first force in the vertical direction. A first, upper section of the block is heated to a brazing-material softening temperature, and at the same time, a second section of the block is brought to a tempering temperature which is lower than the brazing-material softening temperature. Subsequently, the block is not subjected to any force from the outside or is subjected to a second force which is lower than the first force, and the second section of the block is brought to a brazing-material softening temperature. At the same time, the first section is brought to a tempering temperature which is lower than the brazing-material softening temperature.

Method and apparatus for producing a brazed plate heat exchanger block by sectional brazing

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

Heat exchanger

The invention relates to a distribution system () for distributing a fluid () into a container () from a fluid inlet () of the container (). Distribution system () comprises one or more guide plates that form a guide section () and a distribution section () that adjoins the guide section (). Distribution section () has regions () with openings () for allowing fluid () to pass through. The invention also relates to a heat exchanger device () that has a container () with a fluid inlet (), with at least one heat exchanger block () that is arranged in the container (). A distribution system () according to the invention is arranged in the container () above the heat exchanger block ().
