Analytical and Numerical Analysis of Thermal Structure

Abstract

Heat conductive structures were designed for the Miniaturized Heat Switch to improve its parameters which are not satisfying in the prior solution. The thermal conductivity is lower than 1.5 W·K-1 and weight is higher than 55.1 g. To design a new efficient heat conductive structure, it was necessary to make their analytical models to compute thermal conductivity and weight. The parameters computed analytically were verified by numerical analysis which confirmed the accuracy of the calculation. The thermal conductivity of new structures is significantly higher with the most promising concept of 2T-shape structure.Heat conductive structures were designed for the Miniaturized Heat Switch to improve its parameters which are not satisfying in the prior solution.
