THE EFFECTIVE MAGNETIC SYSTEM FOR THE MAGNETOCALORIC REFRIGERATOR

摘要

The magnetic field source system constitutes an important component of magnetic refrigeration device. In this paper we present the results of calculation and designing the effective magnetic system up to 1.9 T. All numerical calculations of the design of the magnetic system are validated by using to two-dimensional finite element method simulations. The magnetic system was developed using Nd-Fe-B permanent magnets with the residual induction of each sample is in 1.189-1.206 T. Using finite element method the numerical model of the magnetic system was constructed and as it is shown the fitting between experimental and theoretical results is satisfied.
