Abstract :
Heat exchanger is a device capable of exchanging heat from hot fluid to cold fluid. The parameters that support the heat exchange in the heat exchanger are the amount of heat that can be absorbed the higher the better the performance of the heat exchanger. Heat Exchanger is influenced by heat temperature, cross-sectional area and fluid mass. The heat exchanger in Saguling hydropower one of the water cooler generators in two different units has different materials and designs, namely stainless steel tube material in unit 2 with 216 and CuNi in unit 2 with the number of tubes 180. The highest yield of heat absorption in unit 4 of 623733.3 kj/s and at Unit 2 of 521961.97 kj / s. For the effectiveness of heat exchanger has a value of 0.784 in Unit 2 and has decreased while in unit 4 has a value of effectiveness of 0.823 but has a tendency to remain constant. So that the recommendations of the two units are unit 4's design and materials because they have constant effectiveness and have more affordable economic prices.
