快速溫變試驗箱與冷熱沖擊試驗箱有什么區別？

快速(su)溫(wen)變試(shi)(shi)驗(yan)箱(xiang)與(yu)(yu)冷熱沖擊試(shi)(shi)驗(yan)箱(xiang)有一(yi)些(xie)區別(bie)，快速(su)溫(wen)變試(shi)(shi)驗(yan)箱(xiang)試(shi)(shi)驗(yan)是(shi)在短時間里(li)讓高(gao)溫(wen)降(jiang)至低溫(wen)或低溫(wen)升至高(gao)溫(wen)，形成溫(wen)度(du)(du)(du)變化環(huan)(huan)境;冷熱沖擊試(shi)(shi)驗(yan)箱(xiang)試(shi)(shi)驗(yan)則是(shi)利用(yong)試(shi)(shi)驗(yan)設備來模擬高(gao)溫(wen)與(yu)(yu)低溫(wen)之(zhi)間的瞬(shun)間變化環(huan)(huan)境，實(shi)現的是(shi)溫(wen)度(du)(du)(du)的驟然(ran)變化。兩(liang)者(zhe)之(zhi)間大的區別(bie)是(shi)在于溫(wen)度(du)(du)(du)變化的速(su)率(lv)。

快(kuai)(kuai)(kuai)速(su)溫(wen)變(bian)試(shi)(shi)驗(yan)(yan)箱與冷(leng)(leng)熱沖擊(ji)試(shi)(shi)驗(yan)(yan)箱不同，它(ta)內(nei)部(bu)只(zhi)有一(yi)個箱體，只(zhi)能在(zai)某(mou)一(yi)時(shi)間內(nei)存在(zai)高溫(wen)或低溫(wen)，溫(wen)度(du)的變(bian)化都(dou)需要升溫(wen)、降溫(wen)來實(shi)現，因為溫(wen)度(du)上升或下降的速(su)率較快(kuai)(kuai)(kuai)，所以(yi)也叫做快(kuai)(kuai)(kuai)速(su)溫(wen)變(bian)試(shi)(shi)驗(yan)(yan)箱，在(zai)溫(wen)變(bian)的速(su)率上來說，達不到冷(leng)(leng)熱沖擊(ji)試(shi)(shi)驗(yan)(yan)箱的效果。

冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)箱(xiang)(xiang)用(yong)來進行冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)，其內部構造與快速溫(wen)(wen)(wen)變試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)箱(xiang)(xiang)不同，冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)箱(xiang)(xiang)箱(xiang)(xiang)體(ti)內有兩個溫(wen)(wen)(wen)區(qu)(qu)(qu)，高溫(wen)(wen)(wen)區(qu)(qu)(qu)和(he)低(di)溫(wen)(wen)(wen)區(qu)(qu)(qu)。冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)箱(xiang)(xiang)分為兩箱(xiang)(xiang)式(shi)(shi)和(he)三箱(xiang)(xiang)式(shi)(shi)，兩箱(xiang)(xiang)式(shi)(shi)冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)箱(xiang)(xiang)采(cai)用(yong)上下吊索平臺移動的(de)方式(shi)(shi)，在高溫(wen)(wen)(wen)區(qu)(qu)(qu)和(he)低(di)溫(wen)(wen)(wen)區(qu)(qu)(qu)來回移動，形(xing)成(cheng)冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)的(de)效(xiao)果(guo);三箱(xiang)(xiang)式(shi)(shi)的(de)冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)箱(xiang)(xiang)則(ze)采(cai)用(yong)的(de)是三箱(xiang)(xiang)體(ti)的(de)設計，分為高溫(wen)(wen)(wen)區(qu)(qu)(qu)、低(di)溫(wen)(wen)(wen)區(qu)(qu)(qu)和(he)測(ce)試(shi)(shi)區(qu)(qu)(qu)，試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)時(shi)將試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)物品放置于測(ce)試(shi)(shi)區(qu)(qu)(qu)，通過高溫(wen)(wen)(wen)區(qu)(qu)(qu)和(he)低(di)溫(wen)(wen)(wen)區(qu)(qu)(qu)的(de)溫(wen)(wen)(wen)度氣(qi)流來對(dui)測(ce)試(shi)(shi)區(qu)(qu)(qu)的(de)試(shi)(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)(yan)物品進行交替(ti)沖(chong)擊(ji)(ji)(ji)，形(xing)成(cheng)冷(leng)熱(re)(re)沖(chong)擊(ji)(ji)(ji)效(xiao)果(guo)。
