MATERIALS USED IN VARIOUS HEAT EXCHANGERS FOR CONSTRUCTION AND THERMAL ENERGY STORAGE

This paper summarizes the current research using various materials for heat exchanger construction and storing the thermal energy into various phase change materials or thermal energy storing materials. In this paper a various materials used in the heat exchangers with parallel, counter and cross flow fluid patterns were studied. The materials are suitable for low, medium and high temperature range along with natural and artificial materials considered in this study. The materials are metal, non- metal, metal alloys, metal foam, porous, metal mesh, polymers, fibres, porous materials used in heat exchangers like compact, plate, asymmetric plate, plate-fin, intermediate, modular, ground, earth-air, ceramic heat exchangers etc. The metallic materials like copper, aluminium, stainless steel, titanium, brass etc are used for high temperature liquid and gases. The low temperature liquids like water and glycerol the materials used are ABS, PP,PS, PET, Phenolic, PVC, PC, Epoxy, PPMA, PTFE, Elastomer, LDPE, HDPE etc. The thermal storing materials used to store the thermal energy, sensible and latent heat.
