ADS2K低温系统超流氦换热特性研究

摘要

Based on the research in the ADS 2K cryogenic system,the peak heat versus the diameter of the riser pipe was analyzed.The superfluid helium peak heat with different helium bath temperature was measured,and the design method of the riser pipe of the cryostat was proposed.The design of the riser pipe of the cryostat in the ADS cryogenic system was demonstrated to be reasonable.%以ADS 2K低温系统为研究平台,分析了恒温器结构参数中上升管与峰值热量的关系,测量了超导腔液氦池中不同工作温度下的超流氦峰值热量,最后给出了恒温器上升管的设计方法,并验证了ADS低温恒温器上升管设计的合理性.
