摘　　要：针对液化天然气发动机所特有的冷能进行回收利用,可以提高发动机的热效率,为了能够对其能量回收系统进行模拟开发了一冷能回收模拟试验台。通过分别设计测量显示系统、温差发电器、冷却模拟系统和LNG气化模拟系统,实现了能量的回收,然后基于该实验台进行了试验研究,研究结果显示,由于温差发电器尺寸较小使得冷端和热端温差不会太大;通过提高液化天然气的流量,可以降低冷端的温度,进而提升温差发电器两端温差,提高温差发电器输出电压。One simulation test bed was designed and developed in order to recycle liquefied natural gas(LNG)engine cold energy which will improve engine thermal efficiency.The simulation test bed was realized through the design of the measurement results show part,thermoelectric generator modules,engine cooling system simulation part,and LNG gasification simulation part which can demonstrate the energy recovery system.Then the experiment was done based on this test bed and the results show that the temperature difference can not be very big due to the small size of the thermoelectric generator modules.It also depicts that the temperature difference can be enlarged by increasing the LNG mass flow because this can decrease the cold end temperature.
