本文重点提出一种用于计算水下载人潜水器热交换的传热模型，该传热模型首次综合考虑了水下隔热层、空调、蓄热体、热源等因素对舱内温度的影响，在做出一定假设后，问题可简化为一维非稳态传热问题，采用有限差分方法对导热微分方程进行数值求解，并利用Matlab实现程序化计算。利用该程序对某工程算例的不同工况进行计算，将结果与AMESim仿真结果对比分析，验证所提传热模型及计算方法的正确性。该模型与方法为今后水下载人潜水器在热舒适性问题上的研究设计提供了一种便捷技术手段。
The article provides a heat transfer model for solving manned submersibles heat exchange problem. The factors including thermal insulation、heat capacity、air conditioning are firstly take into account in this model. With some assumptions, the problem can be simplified to 1D unsteady heat transfer, A finite difference method is used to numerically solve the problem and is carried out using Matlab codes. Calculating different thermal condition for a submersible based on Matlab program. The results are compared with the simulation results of AMESim, which will verify the proposed heat transfer model and calculation method. The method will provide a more convenient approach to help research on thermal comfort of manned submersible.
