摘要: New cooling technologies have fascinated scientific researchers for decades. Due to significant progress in material technology, huge magneto/electro/elasto/barocaloric effects have become available. These effects are changes in temperature and/or entropy of the body by the application or removal of external fields. Material having at least two caloric effects is called multicaloric. Interest in this group of substances is caused by the fact that the interaction of fields having different nature may result in a substantial increase in caloric effects [1]. As a consequence, multicalorics are extremely promising materials for solid-state cooling. However, at present the multitude of coupling of caloric and ferroic (ie nonlinear dependence of the polarization, magnetization, and elastic stresses on the external parameters) effects is not well defined. According to the numerical calculations performed on the basis of the model presented in [2], multicaloric (magneto/electro/elasto) system of 30 layers provides cooling of 31 K. Unfortunately, the main drawbacks of the magnetocaloric structures are related to high costs and large sizes of magnetic field sources. The barocaloric effect has the same disadvantages that make it difficult to use them in spot cooling systems. Therefore, the electric field remains the only option for the generation of caloric effects in compact devices. For the realization of microcoolers, we propose the following scheme. The basic strategy relies on strengthening of the electrocaloric effect. For this purpose, an additional piezoelectric layer can be used as a solution. Furthermore, the cooling device consists of a set of thin elements which increases its …
