    摘要： An air-cooled surface condenser has a supply of cooling air which is varied in accordance with the temperature of the condensate to thereby diminish the possibilities of freezeup at below normal ambient temperatures. The condenser has at least two downflow tubes and one reflux tube with the tubes so arranged that the cooling air travels first over the reflux tube and then sequentially over the first and second downflow tubes, and with the tubes being of such dimensions that condensate is formed in the reflux tube. With this arrangement the air supply can be varied in response to drop in condensate temperature at the first downflow tube and thus assure that the air, before reaching those portions of the first downflow tube where condensate has formed, has a temperature which has been elevated by the latent heat of condensation within the reflux tube.
