Abstract
A method is proposed for increasing the thermal efficiency of water pipe heat exchangers by increasing the contact surface of anisotropically porous materials with the air flow. The exchanger consisted of parallel multichannel pipe bundles fixed in a tube plate and placed in a jacket. A mathematical model was constructed to depict both the energy and material cost efficiency of the system. Another model optimized the surface area and configuration of the pipes by accounting for parameters such as air flow rate and specific heat. Tests of the exchangers determined that the porous materials increased thermal efficiency 1.5 to 2 times, cut material consumption by 30-40%, and decreased heat exchanger volume by a factor of 6-8.
