| Abstract: |
| Space refrigerationtechnologyis one of the keytechnologies which restrict the development of the spaceborneinfraredremote sensor technology.Because the infrared remote sensor systemrequires refrigerators that can providegreater cooling capacity andlower refrigerating temperature,the space mechanical cryocooler gradually becomes maindevice of space refrigeration.In this paper,the current engineeringresearch of domestic andforeign space mechanicalcryocooler is reviewed.In particular,the technological problems needed to pay much attention during the developingprocess of space mechanical cryocooler are described combined with JPL technical report about space mechanical cryo-cooler in recent10years. |
