| Abstract: | The temperature of the warm end has a notable effect on the performance of a miniature pulse tube cryocooler (PTC) with limited cooling capacity. Based on the two high frequency miniature non-metallic PTCs, this paper investigated the variation of the lowest no-load temperature of the cold head and co-axial conduction heat lossed with the temperature of the warm end respectively. The quantitative analyses about the effects were performed. The experiments indicated that the performance of the two sample coolers could be improved greatly by lowering the temperatures of the warm ends. |
