摘要： The cool down time for a multi-stage, pulse tube cryocooler is reduced by configuring at least a portion of the acoustic impedance of a selected stage, higher than the first stage, so that it surrounds the cold head of the selected stage. The surrounding acoustic impedance of the selected stage is mounted in thermally conductive connection to the warm region of the selected stage for cooling the acoustic impedance and is fabricated of a high thermal diffusivity, low thermal radiation emissivity material, preferably aluminum.

摘要： An improved pulse tube cooler having a resonator tube connected in place of a compliance volume or reservoir. The resonator tube has a length substantially equal to an integer multiple of 1A wavelength of an acoustic wave in the working gas within the resonator tube at its operating frequency, temperature and pressure. Preferably, the resonator tube is formed integrally with the inertance tube as a single, integral tube with a length approximately 1A of that wavelength. Also preferably, the integral tube is spaced outwardly from and coiled around the connection of the regenerator to the pulse tube at a cold region of the cooler and the turns of the coil are thermally bonded together to improve heat conduction through the coil.
摘要翻译：一种改进的脉冲管冷却器，其谐振管连接代替顺应容积或储存器。谐振管的长度基本上等于谐振管内工作气体中声波的1A波长的整数倍，其工作频率，温度和压力。优选地，谐振管与惯性管一体地形成为具有该波长的大约1A长度的单个整体管。同样优选的是，整体管从冷却器的冷区域向外与冷却器的冷却区域处的回热器和脉冲管的连接部周围隔开，并且线圈的匝圈被热结合在一起以改善通过线圈的热传导。
