摘要
脉冲管制冷机具有结构简单、可靠性高、寿命长、冷端无机械振动源以及没有电磁干扰等优点 ,是适合空间应用的新一代制冷机。文章以一维数值模型描述脉冲管制冷机中的非线性过程 ,利用有限差分方法对此一维模型进行了数值求解 。
Having no moving part in the low temperature region of the cold finger, the pulse tube cryocooler has considerable system advantages over most other types of regenerative refrigerators in terms of simplicity, reliability and vibration It is a innovative cryocooler for space application In this paper, the 1-dimensional model describing the nonlinear process within the pulse tube cryocooler is solved using finite difference method The simulation results are compared with the experiment results.
