Enhancement of heat exchangers with metal foams

Abstract

Removal of the heat is becoming a vital issue for safer operations of today’s technological equipment. The necessity of heat exchangers is underlined at this stage for the sake of the emerging technologies, which are producing more heat than before by the increment of the higher energy demand during their operations. Several methods have been suggested to improve the efficiency of the heat exchangers in last decades by the researchers including the extension of the heat transfer surface by the larger surface areas surrounding the channels. In addition to this fundamental approach (extension of the surface area), alternate methods have been released too including the implementation of metal foams to the heat exchangers as for the extension of the surface.

Keywords: Heat exchangers, surface extension, metal foams.
