Magnetocaloric effect element, manufacturing method thereof, and thermal magnetic cycle device

摘要

Problem to be solved: to provide a magnetocaloric effect element capable of adjusting a thermal output and adjusting mechanical strength, a manufacturing method thereof, and a thermal magnetic cycle apparatus.The magnetocaloric effect element 7 has a plurality of partial elements 30.The plurality of partial elements 30 are cascaded.The plurality of partial elements 30 are a mixture of a plurality of particles and a binder.The partial element 31 includes a plurality of first particles exhibiting a magnetocaloric effect at a first temperature.The partial element 32 includes a plurality of second particles which exhibit a magnetocaloric effect at a second temperature different from the first temperature.The first ratio of the first particle and the binder in the partial element 31 is different from that of the second particle and the binder in the partial element 32.The amount of binder is set so as to supplement the difference in the strength of the material.Diagram
