Abstract: The invention relates to a magnetocaloric lattice element formed by fibres of magnetocaloric material, wherein the fibres are arranged in respective parallel lattice planes, each fibre having a respective mass of magnetocaloric material, the fibres of a given lattice plane do not contact each other but each fibre of a given lattice plane is attached to at least two fibres in a next neighbouring lattice plane, and wherein the magnetocaloric lattice element exhibits exactly one predominant mass-weighted direction of longitudinal fibre extension. When arranged in alignment of its predominant mass-weighted direction of longitudinal fibre extension with an external magnetic field, the magnetocaloric lattice element achieves an advantageous, particularly high magnetization of the magnetocaloric material, and as a consequence improves the performance of the magnetocaloric cooling device.

Abstract: A magnetocaloric cascade contains a sequence of magnetocaloric material layers having different Curie temperatures TC, wherein the magnetocaloric material layers include a cold-side outer layer, a hot-side outer layer and at least three inner layers between the cold-side outer layer and the hot-side outer layer, and each pair of next neighboring magnetocaloric layers of the magnetocaloric cascade has a respective Curie-temperature difference amount ΔTC between their respective Curie temperatures, wherein the hot-side outer layer or the cold-side outer layer or both the hot-side and cold-side outer layer exhibits a larger ratio mΔSmax/ΔTC in comparison with any of the inner layers, m denoting the mass of the respective magnetocaloric material layer and ΔSmax denoting a maximum amount of isothermal magnetic entropy change achievable in a magnetic phase transition of the respective magnetocaloric material layer.

Abstract: A three-dimensional porous catalyst, catalyst carrier or absorbent structure of stacked strands of catalyst, catalyst carrier or absorbent material, composed of layers of spaced-apart parallel strands, wherein parallel strands within a layer are arranged in groups of two or more closely spaced-apart, equidistant strands separated by a small distance, wherein the groups of equidistant strands are separated from adjacent strands or adjacent groups of strands by a larger distance.

Abstract: A three-dimensional porous catalyst, catalyst carrier or absorbent monolith of stacked strands of catalyst, catalyst carrier or absorbent material, composed of alternating layers of linear spaced-apart parallel strands, wherein the strands in alternating layers are oriented at an angle to one another, wherein the distance between inner spaced-apart parallel strands is larger than the distance between outer spaced-apart parallel strands in at least a part of the layers of the monolith.

Abstract: The invention relates to a magnetocaloric device, comprising a field generator, arranged to provide a changing external magnetic field and a magnetocaloric regenerator arrangement. The magnetocaloric regenerator arrangement comprises a magnetocaloric element, wherein the magnetocaloric element comprises magnetocaloric material, and wherein the magnetocaloric regenerator arrangement is arranged to be exposed to the changing external magnetic field of the field generator. Furthermore, the invention is characterized in that the magnetocaloric device further comprises an insulating means wherein the insulating means is arranged such that the magnetocaloric regenerator arrangement is hermetically surrounded by the insulating means.
