| Abstract: | Study on heating the high pressure air by high-temperature and pressure gas is conducted 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. |
