翅片管空冷器換熱器
翅片(pian)管空(kong)(kong)(kong)冷器換熱(re)器的原理是空(kong)(kong)(kong)氣先(xian)經(jing)風機在至管束,風機工(gong)作在大(da)氣溫度下,功率消耗較小(xiao),結構(gou)較簡單,安裝和檢修方便,振(zhen)動小(xiao),運行壽命長,由于空(kong)(kong)(kong)氣的紊(wen)流(liu)(liu)作用,管外對流(liu)(liu)傳(chuan)熱(re)系數較高。目前在國內(nei)的應用較廣泛。但是空(kong)(kong)(kong)氣速度分(fen)布不均勻,壓力損失(shi)較大(da),受日照及氣候變(bian)化影(ying)響較大(da),排(pai)出(chu)的熱(re)空(kong)(kong)(kong)氣較易產生(sheng)回流(liu)(liu)。
