Abstract

L'échangeur de chaleur en forme de plaque comporte plusieurs plaques d'échange séparées par des éléments d'espacement (2). Ces éléments assurent en outre l'étanchéité de l'échangeur. Les plaques d'échange (1) sont absolument planes, c'est-à-dire qu'elles ne présentent aucunes nervures, rainures ou analogues.
