Plate heat exchanger with heat exchanger blocks connected by metal foam

摘要

The invention relates to a plate heat exchanger with at least two heat exchanger blocks. Each heat exchanger block has several sheets, arranged parallel to one another, that form a plurality of heat-exchange passages for fluids. The heat exchanger blocks are joined to one another via joining means and have at least one common header. A metal foam, that joins the outside surfaces of adjacent heat exchanger blocks to one another, is introduced into an interspace of adjacent heat exchanger blocks. In this way, a blanket heat-conductive and non-positive joining is provided between the opposing outside surfaces of adjacent heat exchanger blocks.
