补充资料:空气冷却器
      简称空冷器,以空气作为冷却剂的间壁式换热器,可用作冷却器,也可用作冷凝器。空冷器主要由管束、支架和风机组成。热流体在管内流动,空气在管束外吹过。由于换热所需的通风量很大,而风压不高,故多采用轴流式通风机(见流体输送机械)。
  
  管束的型式和材质对空冷器的性能影响很大。由于空气侧的传热分系数很小,故常在管外加翅片,以增加传热面积和流体湍动,减小热阻。空冷器大都采用径向翅片。目前,空冷器中通常采用外径为25mm的光管,翅片高为12.5mm的低翅管和翅片高为16mm的高翅管。翅片一般用热导率高的材料(最常用的是铝)制成,缠绕或镶嵌到光管上。为强化空冷器的传热效果,可在进口空气中喷水增湿。这样既降低了空气温度,又增大了传热系数。采用空冷器可节省大量工业用水,减少环境污染,降低基建费用。特别在缺水地区,以空冷代替水冷,可以缓和水源不足的矛盾。(见彩图)
