- 摘要:
- 以高温高压燃气加热高压纯空气为研究背景,用平均温差法对气一气热管换热 器设计计算,进行结构方案设计,采用有效度一传热单元数法对换热器传热进行校核计算。设 计换热器为圆柱形筒壁结构,出口为渐缩型喷管结构,采用半轴比为211的椭圆形热管。
- Abstract:
- Study 011 heating the high pressure air by high-temperature and pressure gas is con· ducted in this paper.The design calculation and the structural design of the gas to gas heat-pipe heat exchanger are carried out by the mean temperature difference method.The check calculation of the exchanger is performed with validity-heat transfer unit number method.The structure of the exchanger body is a cylinder and its outlet is a contracting-expanding nozzle.The heat-pipes are 1/2 half axis ratio ellipse pipes.
