冷熱沖(chong)擊試驗箱(xiang)和高低溫試驗箱(xiang)的(de)區(qu)別在哪里？

冷熱沖擊試驗箱(xiang)和(he)高(gao)低溫(wen)試驗箱(xiang)的區別如下：

冷熱沖擊試驗(yan)箱(xiang)就是在(zai)一(yi)瞬間從高(gao)溫降到低(di)溫，或(huo)低(di)溫升到高(gao)溫的試驗(yan)箱(xiang)體(ti)。它的特(te)點就是一(yi)個字(zi)快

高低溫(wen)試(shi)驗箱就是只能做高溫(wen)和低溫(wen)試(shi)驗，而且它的升降溫(wen)速率不交慢(man)。

高(gao)低(di)溫(wen)(wen)試驗(yan)箱(xiang)是(shi)一高(gao)溫(wen)(wen)低(di)溫(wen)(wen)的試驗(yan)設備(bei)，但(dan)它(ta)不能時間(jian)達(da)到(dao)從(cong)高(gao)溫(wen)(wen)到(dao)低(di)溫(wen)(wen)的試驗(yan)要(yao)求(qiu)，因為它(ta)從(cong)高(gao)溫(wen)(wen)150℃切換至低(di)溫(wen)(wen)-65℃，需(xu)(xu)要(yao)比(bi)較長(chang)的時間(jian)來(lai)完成，很(hen)顯然是(shi)由逐步(bu)降溫(wen)(wen)來(lai)達(da)到(dao)試驗(yan)條件的，比(bi)如我做從(cong)常溫(wen)(wen)~150℃，的高(gao)溫(wen)(wen)需(xu)(xu)要(yao)在35分(fen)鐘內(nei)完成，但(dan)是(shi)做完高(gao)溫(wen)(wen)試驗(yan)后我需(xu)(xu)要(yao)在3分(fen)鐘內(nei)達(da)到(dao)-65℃的環境(jing)條件。那(nei)么(me)選擇常規高(gao)低(di)溫(wen)(wen)試驗(yan)箱(xiang)就不行了，因為不能達(da)到(dao)你要(yao)的試驗(yan)需(xu)(xu)求(qiu)。

冷(leng)熱(re)沖擊試(shi)驗箱(xiang)主要是做高溫(wen)、低溫(wen)的試(shi)驗設備，其特殊性能表(biao)(biao)現在(zai)瞬間從高溫(wen)到(dao)低溫(wen)、或低溫(wen)到(dao)高溫(wen)的轉(zhuan)換速率(lv)，只(zhi)需10秒內(nei)可從高溫(wen)150℃轉(zhuan)換至低溫(wen)-65℃，恢(hui)復時間5分鐘以內(nei)完成，這就(jiu)是冷(leng)熱(re)沖擊試(shi)驗箱(xiang)的轉(zhuan)換速率(lv)的表(biao)(biao)現。

冷熱沖(chong)擊(ji)(ji)試驗箱主要(yao)用(yong)來做溫(wen)(wen)度(du)沖(chong)擊(ji)(ji)測(ce)試，特(te)點是溫(wen)(wen)度(du)的(de)轉(zhuan)換時間(jian)短(duan)變化快以形成對產品(pin)的(de)溫(wen)(wen)度(du)沖(chong)擊(ji)(ji)。在(zai)(zai)瞬(shun)間(jian)下經(jing)*溫(wen)(wen)及極(ji)低(di)溫(wen)(wen)的(de)連續環境下所能忍(ren)受的(de)程(cheng)度(du), 在(zai)(zai)最短(duan)時間(jian)內試驗其因熱脹冷縮(suo)所引起的(de)化學變化或物理傷害，確認產品(pin)的(de)品(pin)質(zhi)。 冷熱沖(chong)擊(ji)(ji)試驗箱主要(yao)用(yong)來做溫(wen)(wen)度(du)沖(chong)擊(ji)(ji)，特(te)點是溫(wen)(wen)度(du)的(de)轉(zhuan)換時間(jian)短(duan)變化快以形成對產品(pin)度(du)沖(chong)擊(ji)(ji)。在(zai)(zai)瞬(shun)間(jian)下經(jing)*溫(wen)(wen)及極(ji)低(di)溫(wen)(wen)的(de)連續環境下所能忍(ren)受的(de)程(cheng)度(du), 只(zhi)需(xu)10秒內可從高溫(wen)(wen)150℃轉(zhuan)換至低(di)溫(wen)(wen)-65℃，恢復(fu)時間(jian)5分鐘以內完成。

高(gao)低(di)溫(wen)(wen)(wen)(wen)試驗(yan)箱是一(yi)款做高(gao)溫(wen)(wen)(wen)(wen)低(di)溫(wen)(wen)(wen)(wen)的(de)(de)(de)試驗(yan)設備，但它不能在(zai)(zai)短時(shi)間(jian)達到(dao)從高(gao)溫(wen)(wen)(wen)(wen)到(dao)低(di)溫(wen)(wen)(wen)(wen)的(de)(de)(de)試驗(yan)要(yao)求，因(yin)為它從高(gao)溫(wen)(wen)(wen)(wen)150℃切換至低(di)溫(wen)(wen)(wen)(wen)-65℃，需要(yao)比較(jiao)長的(de)(de)(de)時(shi)間(jian)來完(wan)(wan)成(cheng)，很(hen)顯然是由逐步降溫(wen)(wen)(wen)(wen)來達到(dao)試驗(yan)條件的(de)(de)(de)，比如我做從常溫(wen)(wen)(wen)(wen)~150℃，的(de)(de)(de)高(gao)溫(wen)(wen)(wen)(wen)需要(yao)在(zai)(zai)35分(fen)鐘內(nei)完(wan)(wan)成(cheng)，但是做完(wan)(wan)高(gao)溫(wen)(wen)(wen)(wen)試驗(yan)后我需要(yao)在(zai)(zai)3分(fen)鐘內(nei)達到(dao)-65℃的(de)(de)(de)環境條件。

這就是(shi)他們二者(zhe)之間(jian)(jian)的(de)區別(bie)。 冷(leng)熱(re)沖(chong)(chong)驗(yan)箱(xiang)（高低(di)溫(wen)(wen)(wen)(wen)(wen)沖(chong)(chong)擊試(shi)(shi)(shi)(shi)驗(yan)箱(xiang)）低(di)溫(wen)(wen)(wen)(wen)(wen)試(shi)(shi)(shi)(shi)驗(yan)箱(xiang)的(de)功能在(zai)于(yu)兩(liang)者(zhe)的(de)溫(wen)(wen)(wen)(wen)(wen)度變(bian)化速率(lv)，冷(leng)熱(re)試(shi)(shi)(shi)(shi)驗(yan)箱(xiang)是(shi)通(tong)過突變(bian)的(de)溫(wen)(wen)(wen)(wen)(wen)度環境對產品試(shi)(shi)(shi)(shi)件(jian)進行溫(wen)(wen)(wen)(wen)(wen)度沖(chong)(chong)擊，不(bu)同的(de)結構轉換(huan)時間(jian)(jian)略有不(bu)同，三箱(xiang)式冷(leng)熱(re)沖(chong)(chong)擊試(shi)(shi)(shi)(shi)驗(yan)箱(xiang)轉換(huan)時間(jian)(jian)小(xiao)于(yu)3秒(miao)，二箱(xiang)式冷(leng)熱(re)沖(chong)(chong)擊試(shi)(shi)(shi)(shi)驗(yan)箱(xiang)的(de)轉換(huan)時間(jian)(jian)小(xiao)于(yu)5秒(miao)，但不(bu)論那種結構，其恢復時間(jian)(jian)均需小(xiao)于(yu)或(huo)等于(yu)5分鐘(zhong)；而(er)高低(di)溫(wen)(wen)(wen)(wen)(wen)試(shi)(shi)(shi)(shi)驗(yan)箱(xiang)是(shi)可以模擬高溫(wen)(wen)(wen)(wen)(wen)恒(heng)溫(wen)(wen)(wen)(wen)(wen)條件(jian)、低(di)溫(wen)(wen)(wen)(wen)(wen)恒(heng)溫(wen)(wen)(wen)(wen)(wen)條件(jian)和高低(di)溫(wen)(wen)(wen)(wen)(wen)交(jiao)替變(bian)化條件(jian)的(de)實驗(yan)，其溫(wen)(wen)(wen)(wen)(wen)度交(jiao)變(bian)速率(lv)降溫(wen)(wen)(wen)(wen)(wen)一般在(zai)小(xiao)于(yu)1.5度每(mei)分鐘(zhong)，升溫(wen)(wen)(wen)(wen)(wen)速率(lv)小(xiao)于(yu)3度每(mei)分鐘(zhong)。

冷熱沖擊(ji)(ji)試(shi)(shi)驗(yan)(yan)箱(xiang)和(he)高(gao)低溫試(shi)(shi)驗(yan)(yan)箱(xiang)的(de)結構區別(bie)在于(yu)冷熱沖擊(ji)(ji)試(shi)(shi)驗(yan)(yan)箱(xiang)一般(ban)是(shi)(shi)三箱(xiang)式或二箱(xiang)式結構，而(er)高(gao)低溫試(shi)(shi)驗(yan)(yan)箱(xiang)的(de)結構是(shi)(shi)單(dan)箱(xiang)體。 冷熱沖擊(ji)(ji)試(shi)(shi)驗(yan)(yan)要用來做(zuo)沖擊(ji)(ji)測試(shi)(shi)，特(te)點是(shi)(shi)溫轉換時(shi)間(jian)短變(bian)化(hua)快以形(xing)成對產溫度沖擊(ji)(ji)。

高(gao)(gao)低(di)溫(wen)試(shi)驗(yan)箱(xiang)又(you)稱(cheng)高(gao)(gao)低(di)溫(wen)交變濕熱試(shi)驗(yan)箱(xiang)，即在一定(ding)的時(shi)間內從一個溫(wen)度(du)(du)及濕度(du)(du)逐(zhu)漸轉至(zhi)另一溫(wen)度(du)(du)及濕度(du)(du)。溫(wen)度(du)(du)變化慢且(qie)帶濕度(du)(du)。
