基于ANSYS的热板优化设计

An Optimization Design for Hot Plates Based on ANSYS

结合1300 mm?500 mm热板的设计实例,讨论了热管等间距等功率分布导致热板表面温差偏大的原因.运用ANSYS软件对热管位置和功率同时进行优化,热板表面温差从12 C?降为5.4 C?,满足工厂使用要求;进一步分析了热管三段式分布,并据此再进行优化,得到热板表面温差为3.85 C?,且优化出来的间距和功率变化符合经验,对三段式热管功率的配比具有指导意义.

Taking the 1300 mm？500 mm hot plate as design example, the paper discusses too big surface temperature difference in hot plates caused by equal spacing and power distribution. This study optimizes simultaneously the position and power of the heat pipe using the ANSYS, and as a result, the hot plate＇s surface temperature difference decreases from 12 ℃ to 5.4 ℃, which can meet the requirements of factory use. It further analyzes the three-step power distribution of the heat pipe and optimizes it and the hot plate＇s surface temperature difference is reduced to 3.85 ℃ and the optimized distance and power conforms to practical experience. The optimization is of guiding significance to the power matching of the three-section heat pipe.
