本申請涉及微(wei)流控領域(yu),特別是(shi)一種微(wei)流控芯片溫度分區控制系統。
背景技術:
1、在(zai)現有技術中,通常(chang)為了讓芯(xin)(xin)(xin)片(pian)能夠在(zai)超高溫環境下(xia)正常(chang)工作,往往會采(cai)用在(zai)芯(xin)(xin)(xin)片(pian)表面加(jia)裝散熱片(pian)給芯(xin)(xin)(xin)片(pian)降溫,以(yi)保證芯(xin)(xin)(xin)片(pian)表面溫度(du)不(bu)會超過芯(xin)(xin)(xin)片(pian)正常(chang)工作時所(suo)要(yao)(yao)求(qiu)的(de)溫度(du)。然而在(zai)低(di)溫環境下(xia),要(yao)(yao)想(xiang)讓芯(xin)(xin)(xin)片(pian)正常(chang)工作,則需(xu)要(yao)(yao)一(yi)個成本低(di)廉并且(qie)簡單有效的(de)解決方(fang)案(an)。
2、現(xian)有(you)的(de)加(jia)(jia)(jia)(jia)熱(re)(re)(re)電(dian)(dian)路(lu),一(yi)般都是對(dui)(dui)電(dian)(dian)路(lu)整體(ti)進行加(jia)(jia)(jia)(jia)熱(re)(re)(re),其(qi)特(te)征(zheng)在于包(bao)括電(dian)(dian)源、加(jia)(jia)(jia)(jia)熱(re)(re)(re)控制開(kai)(kai)(kai)(kai)關(guan)(guan)(guan)(guan)、發熱(re)(re)(re)器件(jian)(jian)(jian)和(he)導(dao)熱(re)(re)(re)金屬(shu)(shu)片(pian)。電(dian)(dian)源、開(kai)(kai)(kai)(kai)關(guan)(guan)(guan)(guan)部(bu)(bu)件(jian)(jian)(jian)、發熱(re)(re)(re)器件(jian)(jian)(jian)串接(jie)(jie)(jie)成回路(lu),發熱(re)(re)(re)器件(jian)(jian)(jian)與(yu)(yu)(yu)導(dao)熱(re)(re)(re)金屬(shu)(shu)片(pian)接(jie)(jie)(jie)觸。工(gong)作原理將(jiang)導(dao)熱(re)(re)(re)金屬(shu)(shu)片(pian)緊貼到(dao)芯片(pian)的(de)上(shang)表面,發熱(re)(re)(re)器件(jian)(jian)(jian)產(chan)生熱(re)(re)(re)量(liang),導(dao)熱(re)(re)(re)金屬(shu)(shu)片(pian)將(jiang)熱(re)(re)(re)量(liang)傳遞(di)給(gei)芯片(pian),對(dui)(dui)芯片(pian)進行加(jia)(jia)(jia)(jia)熱(re)(re)(re);一(yi)個電(dian)(dian)路(lu)中個只(zhi)有(you)一(yi)個開(kai)(kai)(kai)(kai)關(guan)(guan)(guan)(guan)控制加(jia)(jia)(jia)(jia)熱(re)(re)(re)的(de)關(guan)(guan)(guan)(guan)閉(bi)與(yu)(yu)(yu)開(kai)(kai)(kai)(kai)啟。開(kai)(kai)(kai)(kai)關(guan)(guan)(guan)(guan)部(bu)(bu)件(jian)(jian)(jian)接(jie)(jie)(jie)通(tong)電(dian)(dian)路(lu),發熱(re)(re)(re)器件(jian)(jian)(jian)就開(kai)(kai)(kai)(kai)始加(jia)(jia)(jia)(jia)熱(re)(re)(re),開(kai)(kai)(kai)(kai)關(guan)(guan)(guan)(guan)斷開(kai)(kai)(kai)(kai),發熱(re)(re)(re)器件(jian)(jian)(jian)就停(ting)止加(jia)(jia)(jia)(jia)熱(re)(re)(re)。現(xian)有(you)二線法測(ce)溫電(dian)(dian)路(lu)結構將(jiang)恒流源與(yu)(yu)(yu)電(dian)(dian)壓(ya)表同時接(jie)(jie)(jie)在ab兩端(duan),通(tong)過電(dian)(dian)壓(ya)變化檢測(ce)熱(re)(re)(re)電(dian)(dian)阻阻值的(de)變化。這種測(ce)溫電(dian)(dian)路(lu)也(ye)是針對(dui)(dui)電(dian)(dian)路(lu)整體(ti)測(ce)溫,即對(dui)(dui)所有(you)區(qu)(qu)域進行加(jia)(jia)(jia)(jia)熱(re)(re)(re)和(he)測(ce)溫來達(da)到(dao)溫控的(de)效果。由于金屬(shu)(shu)片(pian)的(de)導(dao)熱(re)(re)(re)性有(you)限,導(dao)致(zhi)發熱(re)(re)(re)器件(jian)(jian)(jian)四(si)周溫度較高,離加(jia)(jia)(jia)(jia)熱(re)(re)(re)器較遠(yuan)的(de)區(qu)(qu)域溫度較低。不能精(jing)準加(jia)(jia)(jia)(jia)熱(re)(re)(re),會使芯片(pian)不同部(bu)(bu)位(wei)形成溫度差,這會降低芯片(pian)的(de)使用壽命。并且現(xian)有(you)的(de)二線法測(ce)溫電(dian)(dian)路(lu)也(ye)無(wu)法消除(chu)導(dao)線電(dian)(dian)阻隨溫度變化的(de)影響并且無(wu)法做到(dao)分(fen)區(qu)(qu)域精(jing)確測(ce)溫。
