摘　　要：设计并试验了一种低温吸附压力恢复系统组合换热器,它由列管换热器和翅片管换热器组成,用来冷却负压高温高速激光器尾气,实现了尾气大温降、小压损。使用皮托排测量尾气平均总压,使用总温排和能量守恒法测量尾气平均总温,得到了准确可信的气流参数,为换热器优化设计提供了必要的依据。A kind of combined heat exchanger applied in cryosorption pressure recovery system, consisted of tube-shell heat exchanger and fin-tube heat exchanger, is designed and experimented, which is used to cool the effluent gas in the high-temperature and high-speed laser so that big temperature drop and small pressure loss are realized. Pitot shelf is used to measure the average total pressure of the effluent gas and total temperature shelf and conservation of energy law are used to measure the average total temperature of the effluent gas, so believable and exact parameters of the effluent gas are achieved, which provides necessary basis for the optimal design of heat exchanger.
