Analisis Kinerja Pipa Kalor Dengan Variasi Diameter Bertingkat Menggunakan Fluida Kerja Air

Abstract

Heat pipe is one form of technology that is applied to equipment related to the heat transfer process. Parameters that affect the performance of the heat pipe include heat sources, wick structures, working fluid and the shape or design of the heat pipe. The purpose of this study was to compare the performance of the heat pipe by varying the stratified diameter on the adiabatic and condenser sections, with variations 1 10 mm - 12 mm - Ø14 mm, variations 2 10 mm - Ø14 mm - Ø16 mm, variations 3 10 mm - Ø16 mm - 18 mm. In this study, the heat pipe is made of copper pipe in which there is a wick screen mesh as the capillary axis. Type K thermocouple is integrated with the NI-9211 and c-DAQ 9271 modules to measure temperature distribution with a heat source from a DC power supply of 30 W, 40 W and 50 W. The results showed that there was a difference in the distribution of boiling temperature and heat flux on the heat transfer coefficient. Where the highest heat coefficient value is produced in the stratified diameter heat pipe test Ø 10mm - Ø 14mm - Ø 16mm with 30 W Daya Input of 205.95 W/m2°C. These variations result in a good boiling process, so it can be said that the performance of the heat pipe works more optimally.
