KM6太阳模拟器冷却系统

太阳模拟器是在冷黑和真空环境中模拟太阳辐照的一种重要设备,其冷却系统主要用于太阳模拟器氙灯的冷却和光学组件的冷却。冷却系统主要由高压水冷却、低压水冷却、低压氮气冷却、氟里昂制冷和去离子水等5部分组成,文章分别介绍了它们的流程和特点。文章参考了ESTEC冷却系统的经验,对KM6太阳模拟器冷却系统进行了优化设计,特别采用了去离子水、密闭循环、模块化机组、PCL控制系统等多种技术,提高了系统的可靠性。此系统设计方法可以应用到其他类似太阳模拟器冷却系统和大型常温冷却系统的设计。

Cooling Systems in KM6 Solar Simulator

The solar simulator is an important facility for simulating solar radiation in the vacuum and low temperature environment. Xenon lamp and optics subassembly are cooled by cooling systems in KM6 salor simulator. Cooling Systems are comprised of high pressure water cooling, low pressure water cooling, low pressure GN2 cooling, Freon chilling, deionized water and so on. Schematic diagrams are presented and characteristics of cooling systems are discussed. The cooling system design is optimized according to cooling systems in ESTEC, especially in techniques such as deionizing water, airtight cycle, modularity unit, PLC control system and so on to improve its reliability. The design techniques of these cooling systems can be useful for other simular cooling systems in similar solar simulators and large scale normal temperature cooling systems.
