摘　　要：To improve the wall surface hydrophilicity of a tube type indirect evaporative cooler,a new method adopting porous ceramics is proposed.This method realizes the combination of porous ceramics and the evaporative cooling technique.The design calculation of the porous ceramics tube type dew point indirect evaporative cooler are carried out from such aspects as the volumes and status parameters of the primary and secondary air,the cooler structure,the heat transfer of the solid porous ceramic tubes and the resistance of the cooler.The calculation results show that the design is reasonable.Finally,based on the design calculation,the porous ceramics tube type dew point indirect evaporative cooler is successfully manufactured.为了提高管式间接蒸发冷却器壁面的亲水性,提出了一种采用多孔陶瓷材料的新方法.该方法将多孔陶瓷材料与蒸发冷却技术有机结合,从一次空气风量和二次空气风量、一次空气状态参数和二次空气状态参数、冷却器结构、固体多孔陶瓷管的传热以及冷却器阻力等方面对多孔陶瓷管式露点间接蒸发冷却器进行了设计计算.计算结果表明该设计合理可行.最后,依据设计制作出多孔陶瓷管式露点间接蒸发冷却器.
