摘要
提出新型高效液氮汽车主换热器的数学模型 ,并对其传热特性进行动态模拟仿真 ,得到新型无霜换热器空气侧、氮气侧以及换热器管壁的温度分布 ,三者自身的温度分布 ,三者相互影响情况比较合理。氮气的出口温度为 2 93.0 5 K。与设计要求温度 2 93.15
The high efficiency heat exchanger model of liquid nitrogen vehicles has been studied and the heat transfer characteristics have been simulated by computer. The temperature distributing of air side, nitrogen side and pipe wall of the free-frost heat exchanger have been got and the influence among them is reasonable. The temperature of nitrogen out from heat exchanger is 293.05K, it is approximate to that is designed.
