摘　　要：建立了紧凑板翅式换热器的动态数学模型.为了满足系统快速动态仿真的需要,采用容阻特性建模技术建立了紧凑板翅式换热器的仿真模型.在相同的运行条件下,对不同的高温板翅固体材料进行了稳态和动态仿真研究.结果表明:在不同的材料条件下,高温板翅式换热器的稳态性能基本相同;但不同材料的动态特性时间不同,硅碳陶瓷材料具有较小的延迟时间,常规高温合金材料延迟较大.To better optimize the power system and improve the efficiency, the research and optimization of high temperature compact plate-fin heat exchanger （CPFHE） is very important. Dynamic mathematical model of CPFHE is established, and Volume-Resistance dynamic model is also completed based on the distributed and lumped parameter technique for the demand of the rapidly dynamic simulation. Under the same operating condition, the steady-state and transient simulation is studied for different high plate fin materials. The steady results indicate that the steady performances are almost consistent; but the dynamic results indicate SiC ceramic has the shorter delay time, while the common alloy has longest delay time, which can be referred for design and optimization of CPFHE control system.
