冷熱沖擊試驗(yan)機制(zhi)冷(leng)(leng)系統的散(san)熱(re)(re)方(fang)式(shi)(shi)有(you)兩種，一種是：風(feng)冷(leng)(leng)式(shi)(shi)；另一種則是：水冷(leng)(leng)式(shi)(shi)。風(feng)冷(leng)(leng)式(shi)(shi)的工(gong)作方(fang)式(shi)(shi)就是利用(yong)風(feng)機送風(feng)把(ba)熱(re)(re)量帶走，而水冷(leng)(leng)式(shi)(shi)則是利用(yong)水塔工(gong)程運轉水來導(dao)熱(re)(re)的方(fang)式(shi)(shi)把(ba)熱(re)(re)量帶走。兩者均有(you)利與(yu)弊。比如風(feng)冷(leng)(leng)式(shi)(shi)的安(an)裝(zhuang)方(fang)式(shi)(shi)簡單(dan)，顧客不需要再提供場地安(an)裝(zhuang)水塔及水管(guan)等工(gong)程，而且(qie)成本便宜些許，但(dan)是散(san)熱(re)(re)會直接在房間里(li)會導(dao)致房間溫(wen)度過(guo)高(gao)。水冷(leng)(leng)式(shi)(shi)的散(san)熱(re)(re)效果更快。需在室外安裝每小時冷(leng)卻(que)水(shui)量為10噸的(de)(de)循環冷(leng)卻(que)水(shui)塔，由用(yong)戶提供(gong)。下面上海寶試儀器就(jiu)仔細來講(jiang)(jiang)講(jiang)(jiang)其中的(de)(de)原理：

     冷(leng)(leng)(leng)熱沖擊(ji)試驗箱采用一套進(jin)口德國比(bi)澤(ze)爾(er)半封閉壓縮機所組(zu)(zu)成(cheng)的(de)(de)(de)(de)二元復(fu)疊式(shi)水冷(leng)(leng)(leng)制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)。復(fu)疊式(shi)制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)包含一個(ge)高(gao)溫制(zhi)(zhi)熱循(xun)環(huan)和(he)一個(ge)低溫制(zhi)(zhi)冷(leng)(leng)(leng)循(xun)環(huan)，其(qi)連接(jie)容器為蒸發(fa)冷(leng)(leng)(leng)凝(ning)(ning)器，蒸發(fa)冷(leng)(leng)(leng)凝(ning)(ning)器是也到能(neng)(neng)量傳遞的(de)(de)(de)(de)作用，將(jiang)工作室內(nei)熱能(neng)(neng)通過(guo)兩級制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)傳遞出去，實現(xian)降溫的(de)(de)(de)(de)目的(de)(de)(de)(de)。制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)(de)(de)設計應用能(neng)(neng)量調節(jie)技術，一種行(xing)之有效的(de)(de)(de)(de)處(chu)理方(fang)式(shi)既(ji)能(neng)(neng)保證在制(zhi)(zhi)冷(leng)(leng)(leng)機組(zu)(zu)正常(chang)運行(xing)的(de)(de)(de)(de)情況下又能(neng)(neng)對制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)(de)(de)能(neng)(neng)耗及制(zhi)(zhi)冷(leng)(leng)(leng)量進(jin)行(xing)有效的(de)(de)(de)(de)調節(jie)，使制(zhi)(zhi)冷(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)(de)(de)運行(xing)費(fei)用和(he)故障率(lv)下降到較為經濟的(de)(de)(de)(de)狀態(tai)。

     高低溫(wen)沖擊試驗箱制(zhi)冷(leng)(leng)工作原(yuan)理：利用(yong)氟利昂等液體的蒸(zheng)(zheng)發潛熱從被(bei)(bei)冷(leng)(leng)卻物(wu)體中吸(xi)熱而(er)實現制(zhi)冷(leng)(leng)，蒸(zheng)(zheng)汽(qi)壓(ya)(ya)縮(suo)(suo)式(shi)制(zhi)冷(leng)(leng)循環過(guo)程經(jing)(jing)膨脹閥或毛(mao)細管節流進入(ru)蒸(zheng)(zheng)發器(qi)的液體，從周(zhou)圍(wei)物(wu)體中吸(xi)取(qu)蒸(zheng)(zheng)發器(qi)潛熱而(er)蒸(zheng)(zheng)發，蒸(zheng)(zheng)發后變(bian)成(cheng)低溫(wen)低氣壓(ya)(ya)氣體被(bei)(bei)制(zhi)冷(leng)(leng)壓(ya)(ya)縮(suo)(suo)機吸(xi)入(ru)，經(jing)(jing)壓(ya)(ya)縮(suo)(suo)機壓(ya)(ya)縮(suo)(suo)后變(bian)成(cheng)高溫(wen)高壓(ya)(ya)氣體進入(ru)水冷(leng)(leng)冷(leng)(leng)凝器(qi)，在其中冷(leng)(leng)卻變(bian)成(cheng)高壓(ya)(ya)液體，再(zai)經(jing)(jing)膨脹閥或毛(mao)細管進入(ru)蒸(zheng)(zheng)發器(qi)，如(ru)此往復循環，從低溫(wen)處吸(xi)熱實現制(zhi)冷(leng)(leng)，再(zai)將熱量從高溫(wen)處釋放出來。
