| Abstract: | This paper introduces the thermal insulation principle of the reflective multiplate structure, theoretically analyzes and calculates the thermal insulation performance of the reflective multiplate cylindrical structure which will be widely used in engineering. According to various layers of thermal insulation and general working temperature conditions, the calculation method and mathematical program of effective thermal conductivity are also given. On the basis of the above analysis the calculation formula of effective thermal conductivity in certain conditions is obtained. Furthermore, the author, for the first time, presents the idea of Critical Insulation Layer Number(CILN: N_(er)). Finally,the further work for future research is proposed. |
