Summary

The quest for better performance of magnetocaloric devices has led to the development of thermal management devices such as thermal switches, thermal diodes, and thermal capacitors. These elements are capable of controlling the intensity and direction of heat flow between the magnetocaloric material and the heat source or heat sink, and therefore have the potential to simultaneously improve the power density and energy efficiency of magnetocaloric systems. In this work, we have analysed a novel mechanical thermal switch capacitor made of silicon operating as a solid heat transporting device. The material properties and thermal contact resistance between the elements were studied experimentally. We numerically quantified the effects of different operating conditions on the cooling performance and switching ratio of the thermal switch capacitor embedded in a magnetocaloric device. The proposed design provides a compact cooling solution that can be attached directly to the heat reservoir, making it attractive for a variety of applications.
