Several mathematical models of tube type indirect evaporative coolers are introduced and compared.

To improve the hydrophilic of tube type indirect evaporative cooler wall surface,the use of porous ceramics material is put forward,combinated of porous ceramics and evaporative cooling technique,and the design calculation of porous ceramics tube type dew point indirect evaporative cooler is carried out from aspects of air volume,air status parameter,structure,heat-transfer and resistance.

Working Principle and Test Research of Tube Type Indirect Evaporative Cooling Air Conditioning;

This paper defines the entropy generation number and obtains the analytic expressions of entropy generation number for tubular indirect evaporative cooler according to the non - equilibrium thermodynamic theory.

In order to seek efficient tubular indirect evaporative cooler,Several methods of heat and mass exchange enhancement were elaborated,according to the theory of heat exchange enhancement.
