| 摘 要： | 建立了玻璃包覆纯铜丝快速冷却过程温度场的有限元计算模型，模拟得出了冷却过程丝线横断面的温度分布图及节点温度随时间的变化关系。研究了冷却水温度、水流速度对玻璃包覆纯铜丝冷却效果的影响。结果表明:快冷时玻璃层内的温差最大可达45 K/m，铜芯内温差最大为0.12 K/m; 随着冷却水流速增大,冷却效果增强，流速达到0.5 m/s时冷却能力饱和; 冷却水温在283～303 K范围内变化时,冷却效果基本不变。

| Abstract: | The calculate model ,which is the distribution of temperature field of fast cold of pure copper wire covered glass, was established. Using the finite analysis software, the temperature distribution in the cool process was simulated. We have obtained how nodal point temperature changed as the temperature decreased. the influence of the temperature of the cooling water and the velocity of the water on copper wire was investigated. The results show that the glass layer has a temperature difference up to 45 K/μm, the copper core has a temperature difference up to 0.12 K/μm; and that as the cooling water flow rate increases, the cooling effect increases, when the flow rate reaches 0.5 m/s, the cooling effect is the best; and that when the cooling water temperature ranges from 283 K to 303 K, the cooling effect almost remains unchanged. |
