基于傅里叶定律的高温作业专用服装设计

Clothing Design for High-Temperature Operation Based on Fourier Law

摘要: 热防护服是在对高温环境下工作人员设计出的一类能阻挡热量的专业服装，服装的隔热性能是评价热防护服优劣的一个重要指标，就多层热防护服而言，材质一定的条件下，每层的厚度则决定了该防护服的隔热性能。本文基于一定环境温度下，利用傅里叶定律对整个防护服的传热过程进行了研究与分析，建立相应热传导偏微分方程模型及优化改进模型，进而设计出热防护服每层织物的最优厚度。

Abstract: Thermal protective clothing is a kind of professional clothing designed for workers to block heat in high temperature environment. The thermal insulation performance of clothing is an important in-dicator to evaluate the merits of thermal protective clothing. For multi-layer thermal protective clothing, the thickness of each layer determines the thermal insulation performance of the clothing under certain material conditions. In this paper, based on a certain ambient temperature, Fourier law is used to study and analyze the heat transfer process of the whole protective clothing, and the corresponding partial differential equation model of heat conduction and optimization and im-provement model are established, and then the optimal thickness of each layer of the thermal pro-tective clothing fabric is designed.
