The invention discloses a space environment simulation device with a movable heat sink, which is provided with a horizontal cylindrical vacuum chamber with two open ends and a gate, the cylindrical vacuum chamber is internally provided with a cylindrical heat sink, and the cylindrical heat sink is internally provided with a movable heat sink. The cylindrical vacuum chamber is provided with first and second interface assemblies, and the movable heat sink is provided with a third interface assembly. The first connector assembly comprises a refrigeration corrugated pipe, one end of the refrigeration corrugated pipe is connected with the first barrel connector flange through a corrugated pipe connector flange, and the other end of the refrigeration corrugated pipe extends into the vacuum chamber and is in butt joint with a refrigeration pipe inner flange at the barrel-shaped heat sink refrigeration pipe end through a refrigeration pipe outer flange. The second connector assembly comprises a second barrel connector flange and an external flange, and a fixed heater wiring penetrating pipe is arranged on the external flange. And the third interface assembly comprises a closed shell, is provided with a heater joint and a heating corrugated pipe joint which are fixedly connected with the cold end of the movable heat sink armored heater in a sealing manner, and is butted with the heater wiring through pipe. The problem of interface damage caused by thermal expansion and cold contraction of the heat sink and the problem of installation of the heat sink movable part can be solved.
本发明公开了一种具有活动式热沉的空间环境模拟装置,有卧置的两端开口筒形真空室及大门,筒形真空室内有筒形热沉,筒形热沉内有移动热沉。筒形真空室设第一、二接口组件,移动热沉设第三接口组件。第一接口组件包括制冷波纹管,制冷波纹管一端由波纹管接口法兰与第一筒体接口法兰连接,另一端伸入真空室由制冷管外法兰与筒形热沉制冷管端的制冷管内法兰对接。第二接口组件包括第二筒体接口法兰与外接法兰,外接法兰上有固定加热器接线穿管。第三接口组件包括密闭壳体,设有与移动热沉铠装加热器冷端密封固接的加热器接头及加热波纹管接头,其与加热器接线穿管对接。本发明可解决热沉热胀冷缩引起的接口破坏问题以及热沉活动件的安装问题。
