Abstract

The invention provides a magnetic refrigeration assembly and a magnetic refrigerator with the magnetic refrigeration assembly. The magnetic refrigeration assembly comprises a magnetic working medium bed and magnets, wherein the magnetic working medium bed comprises a matrix and a plurality of magnetic working medium cavities formed in the circumferential direction of the matrix; the plurality of magnetic working medium cavities are used for accommodating magnetic working mediums; a part of the plurality of magnetic working medium cavities are connected in series into a first runner; the otherpart of the plurality of magnetic working medium cavities are connected in series into a second runner; the first runner and the second runner are mutually independent; the magnets are rotatably arranged on the magnetic working medium bed; the magnets comprise magnet main bodies and magnet branches; the magnet branches extend from the centers of the magnet main bodies to the position away from thecenters; and the magnet branches are provided with first coincidence positions which coincide with the plurality of magnetic working medium cavities forming the first runner and second coincidence positions which coincide with the plurality of magnetic working medium cavities forming the second runner. According to the technical scheme, the problem of loss of refrigeration capacity due to the fact that inlet amounts of heat exchange fluids of the runners of a magnetic refrigerator in the prior art are not uniform is effectively solved.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a magnetic refrigeration assembly and a magnetic refrigerator with the same. Background technique [0002] Magnetic refrigeration is a green and environmentally friendly refrigeration technology. Its theoretical Carnot cycle efficiency can reach 60%. It has more development potential than vapor compression refrigeration in terms of environmental friendliness and energy saving. The principle is to use the magnetocaloric effect (MCE) of magnetic refrigeration materials: the change of the external magnetic field will cause the change of the magnetic entropy of the material itself, accompanied by heat absorption and heat release. Specifically, the magnetocaloric effect is most significant near the Curie temperature of the magnetic refrigeration material. When an external magnetic field is applied, the magnetic entropy of the material decreases and heat is released; when there is no exter...
