| 摘 要： | 本文针对我们已提出的自然循环与低温热管耦合的新型传热元件进行了初步的数值模拟．基于一些合理的假设，利用一维两相流均相动态模型对液氮在自然循环管路中的瞬时换热量进行了计算，在与实验结果进行比较的基础上，得到了一些有关冷却时间与最低冷却温度的初步结论，并对计算结果进行了分析．

| Abstract: | A, new cryogenic heat transfer unit with the advantages of both the natural cooling circulation and the cryogenic heat pipe, which had been proposed by us. was simulated in this paper. Based on some reasonable assumptions, a one-dimensional homogenous two-phase flow model was used to simulate its natural cooling circulation. Compared with the experimental data, the primary results about the cooling time and the lowest temperature were obtained, and some analyses were also carried out. |
