一、暖手寶的原理是什么

1、硬質固體暖手寶原理

硬質固體暖手寶又被稱(cheng)為電(dian)熱(re)(re)(re)(re)餅，里(li)面填充是保溫(wen)(wen)棉(mian)，采用(yong)雙控溫(wen)(wen)電(dian)熱(re)(re)(re)(re)儲能式結構，逐(zhu)漸釋放熱(re)(re)(re)(re)能。內設自(zi)(zi)(zi)動(dong)過熱(re)(re)(re)(re)保護(hu)裝置(zhi)及自(zi)(zi)(zi)動(dong)保溫(wen)(wen)指示裝置(zhi)，一個(ge)由PTC熱(re)(re)(re)(re)敏(min)電(dian)阻開(kai)關控制(zhi)的小(xiao)電(dian)爐(lu)(lu)，PTC是正溫(wen)(wen)度(du)系(xi)數的熱(re)(re)(re)(re)敏(min)電(dian)阻，當電(dian)流通過時(shi)自(zi)(zi)(zi)身會發熱(re)(re)(re)(re)（電(dian)爐(lu)(lu)的熱(re)(re)(re)(re)量(liang)也會傳導給它(ta)的），當溫(wen)(wen)度(du)到達一定值時(shi)，它(ta)的電(dian)阻會急(ji)劇增大，可以視為斷開(kai)，所以熱(re)(re)(re)(re)寶此時(shi)停止消耗(hao)電(dian)能，之后靠保溫(wen)(wen)棉(mian)對電(dian)爐(lu)(lu)的保溫(wen)(wen)來(lai)緩(huan)慢放熱(re)(re)(re)(re)。

2、軟質液體暖手寶原理

軟質液體(ti)暖(nuan)手寶(bao)(bao)有(you)電(dian)(dian)(dian)(dian)極(ji)式(shi)和電(dian)(dian)(dian)(dian)熱元(yuan)件式(shi)兩大類，是在(zai)固體(ti)電(dian)(dian)(dian)(dian)熱餅的(de)基礎上改(gai)進的(de)。電(dian)(dian)(dian)(dian)極(ji)式(shi)暖(nuan)手寶(bao)(bao)采用電(dian)(dian)(dian)(dian)極(ji)式(shi)加(jia)熱方法(fa)，具有(you)優(you)質控(kong)溫(wen)與熱熔斷(duan)(duan)器雙(shuang)重溫(wen)控(kong)保險。正常(chang)情況下袋內液體(ti)溫(wen)度(du)達到65度(du)時(shi)溫(wen)控(kong)器會自動切斷(duan)(duan)電(dian)(dian)(dian)(dian)路，停(ting)止加(jia)熱，而一(yi)旦溫(wen)控(kong)器控(kong)制失靈，熱熔斷(duan)(duan)器切斷(duan)(duan)電(dian)(dian)(dian)(dian)源，終止加(jia)熱，需更換新產品，請不(bu)要嘗試(shi)修(xiu)復。由于電(dian)(dian)(dian)(dian)極(ji)式(shi)電(dian)(dian)(dian)(dian)暖(nuan)寶(bao)(bao)由于兩個電(dian)(dian)(dian)(dian)極(ji)，直接裸(luo)露在(zai)水中，造成的(de)漏電(dian)(dian)(dian)(dian)風險很大，已(yi)經被(bei)禁用。

電(dian)熱(re)元件式暖(nuan)手(shou)寶(bao)里面有爐絲作為電(dian)阻，是(shi)一(yi)袋(dai)液(ye)體和兩個金屬(shu)片構成的(de)。暖(nuan)手(shou)寶(bao)里面的(de)液(ye)體是(shi)過飽和溶液(ye)，輕(qing)輕(qing)彎曲袋(dai)中金屬(shu)片，彎曲金屬(shu)片時產生的(de)輕(qing)微震動(dong)會(hui)使溶質結晶，而(er)結晶的(de)過程會(hui)釋放熱(re)量，這樣就達到了取暖(nuan)的(de)目的(de)。這種暖(nuan)手(shou)寶(bao)溫度可達50℃左右，可維持(chi)約(yue)1小時。

3、電池式暖手寶原理

電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)式暖(nuan)手(shou)(shou)寶使用(yong)(yong)內(nei)置鋰電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)或者是(shi)5號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進行供電(dian)(dian)(dian)驅動，利用(yong)(yong)電(dian)(dian)(dian)阻(zu)產生熱量的(de)原理(li)進行暖(nuan)手(shou)(shou)。電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)式暖(nuan)手(shou)(shou)寶對比前兩種類型，加(jia)熱方(fang)(fang)式不受市電(dian)(dian)(dian)供電(dian)(dian)(dian)加(jia)熱的(de)約束，可(ke)將溫度(du)迅速提升至(zhi)40℃以(yi)內(nei)，只有將內(nei)置鋰電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)型充滿(man)電(dian)(dian)(dian)，就可(ke)以(yi)在需要(yao)時開啟使用(yong)(yong)，而(er)采用(yong)(yong)5號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)型則更(geng)(geng)方(fang)(fang)便(bian)，可(ke)隨時隨地更(geng)(geng)換(huan)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，尤其(qi)適合外出。
