溫控開關簡介

汽車(che)空調(diao)的溫控開關原理： 

1、溫(wen)控開關(guan)內部(bu)有(you)個雙金(jin)屬(shu)片，具(ju)有(you)不同的(de)熱膨脹(zhang)系(xi)數，這樣就能在(zai)達到(dao)一定范圍的(de)臨界(jie)點溫(wen)度時發生形變使觸點結合，達到(dao)通電的(de)目的(de)，低于這個溫(wen)度范圍后回(hui)復到(dao)起始位置，斷開線路。這是機(ji)械式的(de)。在(zai)溫(wen)控開關(guan)表面會標有(you)數值，例如78或者83等等。 

2、還(huan)有熱電(dian)偶(ou)式(shi)的，也就是不同(tong)的溫(wen)度有不同(tong)的電(dian)阻，行車電(dian)腦獲(huo)取數據后(hou)作出開啟或關閉(bi)的指令。

 3、溫控開關是(shi)控制風扇(shan)轉(zhuan)(zhuan)(zhuan)動(dong)的(de)當水溫88度(du)左(zuo)右溫控開關控制風扇(shan)底(di)數轉(zhuan)(zhuan)(zhuan)100度(du)以上風扇(shan)高速轉(zhuan)(zhuan)(zhuan)溫控開關一般安裝(zhuang)在(zai)水箱上或水管到發動(dong)機缸蓋的(de)地方有3根線的(de)兩根線的(de)看車型不等。 

4、 三條(tiao)線的那一定是(shi)電子溫(wen)控才(cai)有(you)，一條(tiao)是(shi)開關(guan)那過來的負級 一條(tiao)是(shi)接(jie)到干燥瓶那個保護(hu)空(kong)調系統(tong)的開關(guan) 還有(you)一條(tiao)是(shi)電源 。

汽車溫控開關的位置

汽車溫(wen)(wen)(wen)控(kong)(kong)(kong)(kong)(kong)開(kai)關在(zai)空調(diao)操作(zuo)面板(ban)上，溫(wen)(wen)(wen)度傳感器安裝在(zai)空調(diao)進風(feng)(feng)口位置。汽車上的(de)溫(wen)(wen)(wen)控(kong)(kong)(kong)(kong)(kong)開(kai)關是起(qi)溫(wen)(wen)(wen)度控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)的(de)作(zuo)用，主要是空調(diao)溫(wen)(wen)(wen)控(kong)(kong)(kong)(kong)(kong)，其是控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)空調(diao)壓縮(suo)機的(de)，當設置的(de)溫(wen)(wen)(wen)度為25度時(shi)(shi)(shi)車廂溫(wen)(wen)(wen)度達(da)到了(le)25度就會(hui)(hui)關停(ting)壓縮(suo)機，風(feng)(feng)扇(shan)還會(hui)(hui)運轉的(de)，因此溫(wen)(wen)(wen)控(kong)(kong)(kong)(kong)(kong)開(kai)關是控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)空調(diao)壓縮(suo)機，而不是控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)風(feng)(feng)扇(shan)的(de)。汽車溫(wen)(wen)(wen)控(kong)(kong)(kong)(kong)(kong)開(kai)關壞了(le)的(de)表現：汽車在(zai)運行中冷卻系統溫(wen)(wen)(wen)度過高會(hui)(hui)出現水(shui)(shui)溫(wen)(wen)(wen)表指針指向紅線(xian)，水(shui)(shui)溫(wen)(wen)(wen)警示燈(deng)閃亮，甚至沸騰；發(fa)動機在(zai)加(jia)速時(shi)(shi)(shi)伴(ban)隨有明顯的(de)金屬敲擊聲，同(tong)時(shi)(shi)(shi)有動力不足、水(shui)(shui)溫(wen)(wen)(wen)警示燈(deng)閃爍、難以熄火等現象。

大通V90簡介

大通V90底盤(pan)在(zai)外觀上給(gei)人一種霸(ba)氣側漏的感覺。前臉采用了(le)大(da)尺寸(cun)多(duo)邊形的進氣格柵，看上去更具時尚感。另(ling)外在(zai)大(da)燈(deng)方(fang)面也要優于(yu)大(da)通V80，采用了(le)LED的光源。
