Heat Exchanger is a device used to transfer heat between two or more liquids at different temperatures. The purpose of this study is (a) to design efficient shells and tubes using technology to increase heat transfer coefficients at the side of the shell and tube simultaneously, (b) To determine the optimized variables to produce a maximum heat transfer coefficient and a minimal pressure drop, (c) to analyze the effect of applying helical baffle and coiled wire insert technology on overall heat transfer coefficient and pressure drop. On the shell side, segmental technology is modified into helical baffle technology by regulating the tube pitch and distance between baffles. The optimization method used is Genetic algorithm (GA). The variable used for optimization on the shell side is the helical baffle angle (/?) and the distance between the helical baffle (L bc ). Variables used for tube side optimization using coiled wire insert technology are pitch of coiled wire (P) and side length of equilateral triangle (e). The objective function in this study is the overall heat transfer ([/). constraint in this study is a pressure drop AP that cannot exceed the initial design of the heat exchanger. Modeling of heat E-l-04 was successfully carried out. The modeling obtained has a very small deviation value compared to the initial data sheet HE. Deviation of Overall heat transfer E-l-04 = -0.00%. Deviation AP t E-l-04 = -0.22%. The average deviation of all exchanger AP S = 0.00%. Heat exchanger optimization was successfully carried out. This can be seen from the increase in the overall heat transfer value in all heat exchangers. Increasing U at HE-E-1-04 = 2.08%. Shell pressure drops did not experience significant changes, only 0.01% in all Heat exchangers. But the pressure drops on the tube side decreased. Decreasing AP, at HE-E-1-04 = -11.35%.
