國產叉車冷卻係統從結構上來講比較簡單，一般由冷卻風扇、散熱器、jiewenqidengyuanjiangoucheng。lengquefengshanwangwangyoufadongjizhijiedaidong，bingqiefengshanzhuansuyufadongjizhuansuyizhi。lengqueshuiwendekongzhizhuyaoyikaojiewenqi。zheheputongqicheshangcaiyongdeyongganwenqikongzhidedianzifengshan、帶(dai)有(you)調(tiao)節(jie)百(bai)葉(ye)窗(chuang)的(de)散(san)熱(re)器(qi)等(deng)有(you)較(jiao)大(da)區(qu)別(bie)。這(zhe)種(zhong)結(jie)構(gou)的(de)特(te)點(dian)是(shi)維(wei)修(xiu)方(fang)便(bian)，成(cheng)本(ben)低(di)。缺(que)點(dian)是(shi)對(dui)冷(leng)卻(que)水(shui)溫(wen)的(de)控(kong)製(zhi)不(bu)靈(ling)敏(min)。發(fa)動(dong)機(ji)水(shui)溫(wen)的(de)高(gao)低(di)主(zhu)要(yao)是(shi)和(he)節(jie)溫(wen)器(qi)是(shi)否(fou)正(zheng)常(chang)工(gong)作(zuo)、水泵能否建立足夠的壓力、冷卻風扇能否達到標準轉速有關。判斷冷卻係統的故障也應從元件是否正常工作開始：
1、節溫器的檢查

2、水泵的檢查

3、冷卻風扇
風(feng)扇(shan)風(feng)量(liang)的(de)檢(jian)測(ce)可(ke)將(jiang)一(yi)薄(bo)紙(zhi)放(fang)於(yu)散(san)熱(re)器(qi)前(qian)麵(mian)，當(dang)發(fa)動(dong)機(ji)運(yun)轉(zhuan)時(shi)，若(ruo)紙(zhi)能(neng)被(bei)吹(chui)開(kai)，則(ze)說(shuo)明(ming)風(feng)量(liang)足(zu)夠(gou)。這(zhe)和(he)前(qian)置(zhi)發(fa)動(dong)機(ji)的(de)汽(qi)車(che)風(feng)扇(shan)向(xiang)內(nei)吸(xi)風(feng)有(you)區(qu)別(bie)。葉(ye)片(pian)不(bu)能(neng)裝(zhuang)反(fan)，並(bing)應(ying)保(bao)證(zheng)風(feng)扇(shan)放(fang)護(hu)罩(zhao)齊(qi)全(quan)有(you)效(xiao)。
4、散熱器
叉車的散熱器置於車輛的尾部。由於叉車的底盤較低，並且廠內作業環境較差，一些雜物、粉(fen)塵(chen)很(hen)容(rong)易(yi)在(zai)散(san)熱(re)器(qi)表(biao)麵(mian)堆(dui)積(ji)，如(ru)果(guo)不(bu)及(ji)時(shi)清(qing)洗(xi)，就(jiu)會(hui)嚴(yan)重(zhong)影(ying)響(xiang)散(san)熱(re)效(xiao)果(guo)。每(mei)天(tian)作(zuo)業(ye)完(wan)畢(bi)應(ying)對(dui)散(san)熱(re)器(qi)表(biao)麵(mian)進(jin)行(xing)認(ren)真(zhen)地(di)清(qing)洗(xi)，盡(jin)量(liang)避(bi)免(mian)使(shi)用(yong)高(gao)壓(ya)水(shui)槍(qiang)。因(yin)為(wei)散(san)熱(re)器(qi)的(de)管(guan)壁(bi)很(hen)薄(bo)，如(ru)果(guo)清(qing)洗(xi)壓(ya)力(li)過(guo)高(gao)的(de)話(hua)很(hen)容(rong)易(yi)衝(chong)癟(bie)，影(ying)響(xiang)循(xun)環(huan)效(xiao)果(guo)。另(ling)外(wai)，冷(leng)卻(que)水(shui)嚴(yan)禁(jin)使(shi)用(yong)“硬水”，以防止散熱器中產生水垢，導致冷卻水添加不足。
