一种新型换热器的设计与制造

Design and Manufacture of a New Heat Exchanger

在换热器设计中，采用横纹管取代光管、用空心环代替折流板支承，获得了良好的效果。文章通过对横纹管与空心环的传热机理及性能分析，探讨了这种新型换热器的结构设计、制造及应用。

In the design of shell-and-tube heat exchanger, we take transverse convex tube instead of smooth tube and hollow ring instead of baffle.The article discussed a new efficient heat exchanger, especially in structure, manufacture and apply.
