Heat exchanging devices produce an outstanding part in numerous engineering applications. Because of this, a varied sort of researches are undertaking to decrease the size and cost of the heat transfer equipment with high performance by indulging in diverse invaluable works similar to changing its design, incorporating corrugated structures with different dimension with different flow configurations. In this work, the design of double pipe heat exchanger had been modified similar to the plate type model with the incorporation of a corrugated copper plate which separates the hot and cold fluid inside the SS304 material tube. Three baffles at the top and two baffles at the bottom of the plate have been placed to reduce the velocity and heat interaction timing of the fluids. This could enhance the surface area of the plate and point of contact between the plate surface and fluid particle flowing over the plate surface. The experiment had been undergone with the parameters like engendering the flow arrangements of hot and cold fluid in counter current direction, hot fluid in the three sided baffle at the top and cold fluid at the two sided baffle at the bottom. This allowed liquids of differing thermodynamic equilibrium to interact, bringing about thermal transfer to calculate its maximum efficiency. In addition to these factors, the heat exchanging performance has been estimated with the heat transfer coefficient using LMTD method gave 8-10% enhancement in the overall heat transfer coefficient with respect to the mass flow rate.
