摘要

为了指导氩氦刀设计

对氩氦刀低温探针的内外部传热和J-T节流过程进行了稳态模拟

采用有限差分法

考虑了轴向传热和冷端低压流体的气液两相特征

在氩氦刀端部假设与外界恒热流换热

对流体和壁面的温度分布进行了计算

对不同进气温度下氩氦刀的制冷能力进行了比较。低压流体在换热器冷端存在气液两相

高压进气温度降低有利于制冷量提高;当高压进气温度由300 K降至270 K

同时维持冷刀端部有效制冷区域外壁温度基本不变的情况下

外部热流可提高20%左右;如利用半导体模块来预冷高压进气

0.001 kg·s-1氩气流量用4片C1206型制冷片

冷却模块尺寸约20 cm×5 cm×5 cm即可满足要求。
