　　本文以阿爾法磁譜儀（AMS）電子設(shè)備熱控制系統(tǒng)為研究對(duì)象,基于實(shí)際飛行數(shù)據(jù),論證了熱控系統(tǒng)設(shè)計(jì)思路的正確性和有效性,分析了阿爾法磁譜儀探測(cè)器熱控制系統(tǒng)在軌運(yùn)行的基本規(guī)律,研究了國(guó)際空間站（ISS）的操作對(duì)阿爾法磁譜儀熱控制系統(tǒng)的影響,分析了在運(yùn)行過(guò)程中出現(xiàn)的溫度預(yù)警現(xiàn)象規(guī)律和原因,并提出了基于調(diào)節(jié)熱環(huán)境的熱控制建議。本文首先介紹了AMS實(shí)驗(yàn)的目的、意義以及已經(jīng)獲得的物理學(xué)結(jié)果。本文分析了國(guó)際空間站上的外部熱環(huán)境、AMS自身內(nèi)部熱負(fù)荷情況以及熱要求,介紹了AMS熱控制系統(tǒng)的方案。由于例子探測(cè)需要以及與國(guó)際空間站相配合,AMS熱控制系統(tǒng)設(shè)計(jì)思路與以往航天器的“完全包覆式”熱控制不同,AMS熱控制設(shè)計(jì)使用了大熱容材料應(yīng)對(duì)近地軌道熱環(huán)境的周期性劇烈變化。電子設(shè)備熱控制系統(tǒng)實(shí)際運(yùn)行數(shù)據(jù)表明,電子設(shè)備成功啟動(dòng),啟動(dòng)過(guò)程溫度曲線與模擬結(jié)果吻合；斷電時(shí)各電子箱均能保持在最低存活溫度以上；熱工況中各電子箱溫度低于最高存活溫度；軌道周期內(nèi)溫度波動(dòng)處于允許的范圍內(nèi)。長(zhǎng)時(shí)間飛行數(shù)據(jù)證明了熱控制系統(tǒng)設(shè)計(jì)思路的正確性以及熱控制系統(tǒng)的有效性。AMS在國(guó)際空間站上運(yùn)行后,在監(jiān)控過(guò)程中發(fā)現(xiàn),AMS熱控制系統(tǒng)運(yùn)行狀態(tài)受到...
