液(ye)(ye)冷(leng)(leng)(leng)系(xi)統(tong)形式(shi)較為靈活: 可(ke)將電(dian)(dian)(dian)池(chi)單體(ti)或模塊沉(chen)浸(jin)在(zai)(zai)液(ye)(ye)體(ti)中(zhong)(zhong)，也可(ke)在(zai)(zai)電(dian)(dian)(dian)池(chi)模塊間(jian)設置(zhi)冷(leng)(leng)(leng)卻通道，或在(zai)(zai)電(dian)(dian)(dian)池(chi)底部采用冷(leng)(leng)(leng)卻板。電(dian)(dian)(dian)池(chi)與液(ye)(ye)體(ti)直接(jie)(jie)接(jie)(jie)觸時(shi)，液(ye)(ye)體(ti)必須(xu)保證絕緣( 如礦物油) ，避免短(duan)路。同(tong)時(shi)，對液(ye)(ye)冷(leng)(leng)(leng)系(xi)統(tong)的(de)(de)(de)氣密性(xing)要(yao)求也較高。新(xin)能(neng)(neng)源汽(qi)車(che)(che)驅(qu)動系(xi)統(tong)中(zhong)(zhong)一般采用風冷(leng)(leng)(leng)、液(ye)(ye)冷(leng)(leng)(leng)組合的(de)(de)(de)設計來(lai)保證整個系(xi)統(tong)的(de)(de)(de)安全(quan)運轉，其中(zhong)(zhong)液(ye)(ye)冷(leng)(leng)(leng)系(xi)統(tong)依靠冷(leng)(leng)(leng)卻水(shui)泵帶(dai)動冷(leng)(leng)(leng)卻液(ye)(ye)在(zai)(zai)冷(leng)(leng)(leng)卻管道中(zhong)(zhong)循環流(liu)動，通過在(zai)(zai)散(san)(san)熱(re)器的(de)(de)(de)熱(re)交換等過程，冷(leng)(leng)(leng)卻液(ye)(ye)帶(dai)走電(dian)(dian)(dian)動機與控制(zhi)器產生的(de)(de)(de)熱(re)量(liang)。冷(leng)(leng)(leng)卻液(ye)(ye)換熱(re)系(xi)數高、熱(re)容量(liang)大、冷(leng)(leng)(leng)卻速度快，新(xin)能(neng)(neng)源汽(qi)車(che)(che)動力(li)電(dian)(dian)(dian)池(chi)防爆溫(wen)控液(ye)(ye)，對降低高溫(wen)度、提升電(dian)(dian)(dian)池(chi)組溫(wen)度場一致性(xing)的(de)(de)(de)，同(tong)時(shi)，熱(re)管理系(xi)統(tong)的(de)(de)(de)體(ti)積也相對較小，是新(xin)能(neng)(neng)源電(dian)(dian)(dian)池(chi)散(san)(san)熱(re)的(de)(de)(de)理想冷(leng)(leng)(leng)卻液(ye)(ye)。

新能源汽車驅動(dong)(dong)(dong)系(xi)(xi)統中一般采用(yong)(yong)風(feng)冷(leng)(leng)、液(ye)冷(leng)(leng)組合的設計來保證整個系(xi)(xi)統的安(an)全(quan)運轉，其中液(ye)冷(leng)(leng)系(xi)(xi)統依靠冷(leng)(leng)卻水(shui)泵帶動(dong)(dong)(dong)冷(leng)(leng)卻液(ye)在冷(leng)(leng)卻管道中循環(huan)流(liu)動(dong)(dong)(dong)，通過在散熱(re)器(qi)的熱(re)交換(huan)等過程，冷(leng)(leng)卻液(ye)帶走(zou)電(dian)動(dong)(dong)(dong)機與控(kong)制器(qi)產(chan)生的熱(re)量(liang)。鋰離子電(dian)池在生產(chan)時，都要進(jin)行(xing)高(gao)低溫(wen)試(shi)驗(yan)。由于(yu)鋰離子高(gao)溫(wen)有、起(qi)火等風(feng)險，所以對鋰離子進(jin)行(xing)溫(wen)度試(shi)驗(yan)的高(gao)低溫(wen)試(shi)驗(yan)箱(xiang)需要有防爆功(gong)能。冷(leng)(leng)卻液(ye)有良(liang)好(hao)(hao)的使(shi)用(yong)(yong)性(xing)能：具(ju)有良(liang)好(hao)(hao)的流(liu)動(dong)(dong)(dong)性(xing)，能在溫(wen)控(kong)系(xi)(xi)統中很好(hao)(hao)地流(liu)動(dong)(dong)(dong)散熱(re)。良(liang)好(hao)(hao)的使(shi)用(yong)(yong)安(an)全(quan)性(xing)能：不(bu)導電(dian)，電(dian)絕(jue)緣性(xing)好(hao)(hao)，不(bu)燃(ran)不(bu)爆無(wu)燃(ran)點(dian)閃點(dian)，使(shi)用(yong)(yong)安(an)全(quan)。適用(yong)(yong)范圍廣：能廣泛使(shi)用(yong)(yong)于(yu)各種溫(wen)控(kong)散熱(re)場(chang)合。
