【摘要】 从脉冲管制冷机中的核心部件蓄冷器入手,考虑不同情况下气体微团的具体热力过程,循序渐进的分析等温和有温度梯度情况下蓄冷器内部不同相位关系的气体微团的压缩和膨胀过程,得出蓄冷器的泵热效应;并通过一定程度的近似假设,给出蓄冷器内部气体微团的理论制冷量的近似公式,得到影响脉冲管制冷机理论制冷量的关键因素。更多还原

【Abstract】 The thermal process of a gas volume with different phase relationships in a regenerator of pulse tube cooler is analyzed under different assumptions.The heat-pump effect of the regenerator is demonstrated.Also,the theoretical cooling power is gained under some certain assumptions.The key factors for the PTCs is shown.更多还原
