随着红外成像技术的不断进步, 人们对于红外成像系统提出更高要求。针对一种红外成像系统, 使用 Icepak软件对其进行热力学仿真分析, 并将结果与实际情况进行对比验证。在此基础上提出几种散热方案, 并针对每一种方案进行建模与仿真。通过定量化比较, 最终选取最佳方案。该方案既降低系统整体温度, 又使系统内温度分布均匀化。

With the development of infrared imaging technology, people raise higher demand to infrared imaging system. For one kind of infrared imaging system, the paper uses ICEPAK to analyze its thermal condition and compares the result with actual situation. On the basis of this analysis, we apply many cooling methods and analyze each method in ICEPAK. At last we find a best method which can both reduce temperature and unify temperature distribution of system by quantitative comparison.
