%X 本文研究非流固耦合时U形管式换热器的温度场情况。研究方法是：使用UG软件建立U形管式换热器的流体(文中选用水)几何模型，使用ANSYS软件对温度场(水无相变时的温度场)进行模拟。研究结论：随着换热器管程越长、管径越小，流体入口温度越高、流体入口流速越小，换热器换热效果越好。通过模拟分析，能更好地认识U形管式换热器的结构及工作原理，更深入理解该类换热器换热微过程及温度场情况，从而能为U形管式换热器的优化提供一些参考和启示性信息。<br />
The temperature field of U-tube heat exchanger neglecting fluid-solid coupling is researched in this paper. The research methods are as follows: The fluid (water is selected) geometry model of U-tube heat exchanger is established using UG software firstly; then the temperature field (the temperature that there is no phase change) of the models is simulated using ANSYS software. The research conclusions are as following. With the increase of pipe length, the decrease of pipe diameter, the decrease of inlet velocity of fluid and the increase of inlet temperature of fluid, the heat transfer effect is better. Through the simulation analysis, the structure and working principle of U-tube heat exchanger can be better understood; the heat transfer micro process and temperature field of this kind of heat exchanger can be better and more deeply understood; some reference and enlightening information for the optimization of U-tube heat exchanger are provided.
