摘要
采用理论计算和有限元实体模型的方法,对HL-2M装置低温冷凝泵及与其相连接的真空穿透结构进行了温度分布和液氦管热负荷分析。结果显示,低温冷凝泵中液氦管的热稳态热负荷为5.45W,粒子沉积的热负荷为75.68W,真空穿透部分的热负荷为5.04W。所得结果为后续的热应力分析、低温泵流速控制和低温系统的设计提供了参考。
Using the method of theoretical calculation and finite element model in ANSYS code, the studies of temperature distribution and the heat load of the liquid helium tube for the cryopump and the connecting feed through were performed. The results show that the steady heat load of the liquid helium tube is 5.45 W;particle deposition heat load is 75.68 W, and 5.04 W in the feed through. These results could be the reference for thermal stress analysis, cryopump flow velocity control and cryo system designing later.
