Heat exchangers are devices which are used to transfer the thermal energy between two or more fluids. They are used in various industries for space heating, air conditioning and chemical processing. Some heat exchangers which are experienced in our daily lives include pasteurization, radiators and oil coolers in automobiles Heat exchangers have been divided in several ways, based on its flow direction which are parallel or counter flow, types of construction of the heat exchanger like tubular or plate heat exchanger, the ways of contact between the fluids i.e. direct or indirect. The heat exchangers performance is usually depending upon the physical characteristics of the fluid and the material. When a concentric tube is added in the intermediate space of a double pipe heat exchanger, we obtain a triple pipe heat exchanger, we obtain a triple pipe heat exchanger. The performance of the triple is better than the double pipe, as it provides better heat transfer efficiencies. Basically, the additional pipe improves the heat transfer by providing an additional flow passage and a larger area for heat transfer area per unit length of the exchanger.
