高低溫沖擊(ji)試(shi)驗(yan)箱(xiang)保溫材料采用超細(xi)玻(bo)璃(li)纖維，低溫箱(xiang)保溫材料采用聚氨酯發泡、石棉板及超細(xi)玻(bo)璃(li)纖維，保溫效(xiao)果良好，試(shi)驗(yan)箱(xiang)外表面(mian)不結霜，不凝露，低溫箱(xiang)底部有(you)冷(leng)凝水排水口，冷(leng)熱沖擊(ji)箱(xiang)箱(xiang)體上有(you)1個(ge)φ25測試(shi)孔。

三槽式冷(leng)熱(re)沖擊試(shi)驗箱高低(di)制(zhi)(zhi)(zhi)冷(leng)循環均采用逆卡若循環,該循環由兩個(ge)等溫(wen)(wen)(wen)過(guo)程(cheng)(cheng)和(he)(he)兩個(ge)絕熱(re)過(guo)程(cheng)(cheng)組成。過(guo)程(cheng)(cheng)如(ru)下(xia):制(zhi)(zhi)(zhi)冷(leng)劑(ji)經(jing)壓縮(suo)機絕熱(re)壓縮(suo)到較高的壓力(li),消耗了(le)功(gong)使(shi)(shi)排(pai)氣(qi)溫(wen)(wen)(wen)度(du)升高,之后制(zhi)(zhi)(zhi)冷(leng)劑(ji)經(jing)冷(leng)凝器等溫(wen)(wen)(wen)地和(he)(he)四(si)周(zhou)介質進行熱(re)交(jiao)換,將熱(re)量傳(chuan)給(gei)四(si)周(zhou)介質。后制(zhi)(zhi)(zhi)冷(leng)劑(ji)經(jing)閥絕熱(re)膨脹(zhang)做功(gong),這時制(zhi)(zhi)(zhi)冷(leng)劑(ji)溫(wen)(wen)(wen)度(du)降低(di)。最(zui)后制(zhi)(zhi)(zhi)冷(leng)劑(ji)通(tong)過(guo)蒸發器等溫(wen)(wen)(wen)地從溫(wen)(wen)(wen)度(du)較高的物體(ti)吸(xi)熱(re),使(shi)(shi)被(bei)冷(leng)卻物體(ti)溫(wen)(wen)(wen)度(du)降低(di)。此循環周(zhou)而(er)復始從而(er)達到降溫(wen)(wen)(wen)之目(mu)的。
