冷卻塔散熱基本因素

1環(huan)境濕(shi)球(qiu)溫(wen)度：濕(shi)球(qiu)溫(wen)度是(shi)影(ying)響(xiang)冷(leng)(leng)卻(que)塔(ta)(ta)的(de)(de)最大(da)因(yin)素，濕(shi)球(qiu)溫(wen)度越低，冷(leng)(leng)卻(que)水(shui)(shui)塔(ta)(ta)的(de)(de)運(yun)作功能(neng)相對也(ye)越高。2逼近度：出水(shui)(shui)溫(wen)度和環(huan)境濕(shi)球(qiu)溫(wen)度的(de)(de)溫(wen)差。逼近度越大(da)，降溫(wen)越容易。一般來(lai)講，逼近度不小于3℃。3循環(huan)水(shui)(shui)量：冷(leng)(leng)卻(que)循環(huan)水(shui)(shui)進入冷(leng)(leng)卻(que)塔(ta)(ta)的(de)(de)流量。4風量：在一定時間(jian)內(nei)(nei)，冷(leng)(leng)卻(que)水(shui)(shui)塔(ta)(ta)內(nei)(nei)所排(pai)出的(de)(de)散(san)熱風量。風量越多，則大(da)量環(huan)境空(kong)氣(qi)與水(shui)(shui)接(jie)觸(chu)，使蒸(zheng)(zheng)發作用(yong)加速，導致散(san)熱效能(neng)更好。5散(san)熱膠片：在冷(leng)(leng)卻(que)塔(ta)(ta)內(nei)(nei)，一種空(kong)氣(qi)和水(shui)(shui)的(de)(de)接(jie)觸(chu)介質(zhi)。主要是(shi)增加水(shui)(shui)和空(kong)氣(qi)的(de)(de)接(jie)觸(chu)面積，延長(chang)接(jie)觸(chu)時間(jian)，可使蒸(zheng)(zheng)發作用(yong)的(de)(de)空(kong)間(jian)和時間(jian)增加。本文(wen)來(lai)自安徽冷(leng)(leng)卻(que)塔(ta)(ta)轉載請(qing)注明網址：ahlingjie電(dian)話：18963790837
