摘要
Double inlet version pulse tube is analyzed and potential direct current flow is revealed;improvement method of multi--double--inlet version is proposed. An experiment system wasset up. Through eXPeriment, multi--double--inlet version was proved effective to lower therefrigeration temperature: test shows 37K lowest temperature for two double inlet valve and59K lowest temperature for one double inlet valve. This pulse tube has 9.5W/77K coolingcapacity using 55mL valveless. The concept of multi--double--inlet was proposed here for thefirst time.
