A dual media safety heat exchanger

Abstract

The present invention relates to a dual media safety heat exchanger comprising a first medium chamber configured to allow a first medium flow through the first medium chamber, a second medium chamber configured to allow a second medium flow through the second medium chamber and an intermediate chamber arranged between the first medium chamber and the second medium chamber and being configured to separate the first medium chamber from the second medium chamber so that the first medium is prevented from being mixed with the second medium or vice versa in the circumstance of a leak within the safety heat exchanger. The first medium chamber, the second medium chamber and the intermediate chamber are arranged in a stacked manner, the first medium chamber having a first inlet and a first outlet, the second medium chamber having a second inlet and a second outlet, the first medium chamber, the second medium chamber and the intermediate chamber being defined by a plurality of chamber plates having a configuration, wherein the configuration of each chamber plate is substantially identical irrespective of which chamber it is part of. The invention also relates to a method for preparing a dual media safety heat exchanger.
