Embodiment Construction

[0028] The following description illustrates specific embodiments of the invention sufficiently to enable those skilled in the art to practice and reproduce it.

[0029] Such as figure 1 Shown is a schematic cross-sectional structure diagram of the inner and outer double-layer magnetic ring structure in the present invention.

[0030] The inner and outer double-layer magnetic ring structure includes: the outer magnetic ring 1 and the inner magnetic ring 2; the outer magnetic ring 1 is in the shape of a cylinder, and the axis position is provided with a central air gap, which is the working space of the magnetic field system; The inner magnetic ring 2 is installed in the central air gap. The outer magnetic ring 1 and the inner magnetic ring 2 can rotate relatively, or the outer magnetic ring 1 does not rotate, and the inner magnetic ring 2 rotates; or the outer magnetic ring 1 rotates, and the inner magnetic ring 2 does not rotate.

[0031] Such as figure 2 Shown is the sch...

Abstract

The invention discloses an inner and outer double-layer magnetic ring structure. The structure comprises an outer-layer magnetic ring and an inner-layer magnetic ring, the outer-layer magnetic ring is cylindrical, a central air gap is formed in the axis position of the outer-layer magnetic ring, and the central air gap is a working space of a magnetic field system; and the inner-layer magnetic ring is arranged in the central air gap. The invention further discloses a preparation method of the inner and outer double-layer magnetic ring structure. The problem of magnetic leakage of the magnetic refrigeration test system is solved, the magnetic field defined by the inner-layer magnetic ring and the outer-layer magnetic ring has multiple layers, no magnetic leakage exists in the center, and the direction and size of the magnetic field of the magnetic refrigeration test system are adjusted through rotation of the inner-layer magnetic field and the outer-layer magnetic field.

Description

technical field [0001] The invention relates to the field of magnetic refrigeration, in particular to an inner and outer double-layer magnetic ring structure and a preparation method thereof. Background technique [0002] At present, the research on room temperature magnetic refrigerators mainly focuses on the reciprocating and rotary types. The permanent magnetic field used in the reciprocating magnetic refrigerator is a partially closed magnetic circuit magnetic field, and the rotary magnetic refrigerator uses a fully closed magnetic circuit magnetic field. [0003] Based on the material genetic engineering research method, focusing on the key scientific issues of improving the performance of rare earth magnetic refrigeration materials, it is necessary to carry out a full range of research from high-throughput calculation and material design, multi-field regulation and performance optimization, high-throughput preparation and characterization to the operation of magnetic re...
