Verfahren zur Herstellung eines Wärmetauschers und Wärmetauscher

摘要

A heat exchanger (41) is provided in which heat exchanger shells (42) are formed by electro forming about a mandrel. The shells (42) are attached and joined to provide a heat exchanger module. As the shells (42) are not press formed problems with respect to material elongation to achieve deep grooves in the shells (42) are potentially avoided and shells can be created with more desirable thickness to achieve more efficient heat exchange. Furthermore, reduced shell thickness will also reduce weight and therefore improve the acceptability of heat exchangers (41) in particular applications such as those associated with aerospace and automotive sports.
