【摘要】 采用热声发动机驱动脉冲管制冷机,使彻底消除低温制冷机中的运动部件成为可能。作者研制了行波型热声发动机驱动脉冲管制冷机实验台。进行三个脉冲管与行波型热声发动机的配合实验,着重研究了热端气体温度、冷端温降和压力振幅的变化规律。更多还原

【Abstract】 A pulse tube refrigerator driven by a traveling wave thermoacoustic prime engine has no moving parts. A bench of a pulse tube refrigerator driven by a traveling wave thermoacoustic prime engine has been set up and three pulse tubes are experimented on the bench. The experiment focuses on the temperature of the gas in the hot end heat exchanger, the temperature decline of the cold end of the pulse tube and pressure amplitude.更多还原
