Claim Text:
1. A process for producing an open-cell porous shaped heat exchanger body, wherein the shaped heat exchanger body comprises a thermomagnetic material selected from the group consisting of (1) a compound of the general formula (I) (2) an La- and Fe-based compound of the general formulae (II) and/or (Ill) and/or (IV) (3) a Heusler alloy of the MnTP type wherein T is a transition metal and P is a p-doping metal having an electron count per atom e/a in the range from 7 to 8.5, (4) a Gd- and Si-based compound of the general formula (V) (5) an Fe (6) a manganite of the perovskite type, (7) a compound which comprises a rare earth element and is of the general formulae (VI) and (VII) (8) an Mn- and Sb- or As-based compound of the general formulae (VIII) and (IX) said process comprising coating a powder of the thermomagnetic material with a polymeric binder and subjecting said material to a shaping by pressing, optionally with heat treatment, so that the polymeric binder remains as a shell on the particles, wherein the polymeric binder is a two-component epoxy resin, and wherein said porous shaped body has a porosity of 30 to 60%.
