Design Calculation of Porous Ceramics Tube Type Dew Point Indirect Evaporative Cooler

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.
