Abstract

Shell and Tube Heat Exchanger (STHX) is very important for its use in the industrial world which can support the continuity and success of the entire network process. Various kinds of research have been carried out to increase the heat transfer coefficient and effectiveness of Shell and Tube Heat Exchangers (STHX) both experimentally and by simulation. This research examines the increase in heat change coefficient and effectiveness of STHX with variations in baffle angles of 0°, 10°, and 20° with fluid mass flow rates of 2, 4, and 6 kg/s. As a result, STHX with a baffle angle of 0° has the largest heat change coefficient value than STHX with a baffle angle of 10° and 20° both during experiment and simulation, values ​​ranging from 4218 W/m²C and 4226 W/m²C at a baffle angle of 0° when the fluid flow rate is increased to 6 kg/s. Keywords: Shell and Tube Heat Exchanger, baffle angle configuration, double segmental baffle, total heat transfer coefficient, effectiveness, CFD (Computational Fluid Dynamics).

Abstract

The heat load on computer chips during computing performance is the main topic, so a cooling device is needed. Heat sink is one of the tools commonly applied to reduce the heat load during computing performance of computer systems. Various heat sink configurations have been widely developed and studied to obtain designs with the best thermal performance. This research was conducted to investigate the best design on a straight fin heat sink (SFHS) that has the best thermal and hydraulic performance. SFHS with fin thickness variations of 1 mm, 2 mm, and 3 mm are proposed in this study. The numerical method was carried out using the Computational Flui Dynamics program by considering fluid flow velocities of 4 m/s, 6 m/s, 8 m/s and 10 m/s. The numerical results show that the cooling rate of SFHS can be increased by using SFHS with a thickness of 3 mm and a fluid flow velocity of 10 m/s with a maximum Nusselt number value of 59.74. Therefore, it is concluded that the SFHS has prospects for further study and can be applied practically in the field for micro electronic components and computer systems. Keywords: Heat sink, SFHS, Straight fin.
