Kaji Eksperimental Kinerja Loop Heat Pipe Dengan Fluida Kerja Refrigeran R32
ABSTRACT
The problem of cooling electronic components is increasing along with component damage that occurs, one of which is caused by heat flux generates by the processor. Loop heat pipe is a heat pipe that is flowed by two phases of a loop ype heat pipe whose heat is in the same direction. Loop heat pipe has the advantages of large heat transfer, high heat efficiency and strong resistance to gravity. Refrigerant is a medium (fluid) that can absorb heat by evaporation at low temperature and pressure and realease heat by condensing at high temperature and pressure. This research was conducted using a loop type heat pipe with a wick screen mesh 100 with a varying filling ratio and working angle on the evaporator. The temperatur difference value at the input power is 12 Watt with a filling ratio of 60% and working angle 90° is 22,56 °C. The highest effectiveness of the loop heat pipe is at an input power of 12 Watt at a working angle 90° with 18,47%. By doing this research is obtain that the working angle affects the temperature difference and the effectiveness of the loop heat pipe.
