| Abstract: | Based on the structure of the phosphor bronze and lead matrix in the regenerator of G-M cryocooler,numerical simulation of the dynamic laws of the helium temperature in the regenerator of G-M cryocooler is carried out.According to the field synergy principle,the convection heat transfer performance of the regenerator with phosphor bronze and lead matrix is analyzed.Furthermore,the experiments on the refrigerating capability of different kinds of regenerator matrixes are conducted,and the reasonable filling ratio between phosphor bronze and lead is obtained. |
