Method for producing a magnetocaloric heat exchanger element

Abstract

A low-cost, resource-saving, easy-to-perform, preferably harmless and fault-tolerant process is disclosed with which a durable, robust, chemically and mechanically stable heat exchanger element with advantageous thermohydraulic and magnetic properties can be produced. The method comprises: providing a magnetocaloric substrate with a plurality of channels or pores which preferably form continuous channels, immersion of the substrate in a tempered aqueous reaction solution, which leads to an autocatalytic-chemical deposition of a metal coating on the surface of the substrate.
