Description
Summary:The main focus of this research is the characterization of the thermal conductivity of pineapple fibre, hempe fibre, and luffa fibre. These three fibres will be used as cooling pads for indirect evaporative cooling with an added heat pipe as a heat exchanger. The characterization of the thermal conductivity of pineapple fibre, hempe fibre, and luffa fibre was investigated experimentally by using a thermoelectric-based thermal conductivity apparatus. The principle of this tool is to make a temperature difference between the two ends of the material. One end is given the heat, while the other end is maintained its temperature (35°C, 40°C, 45°C, 50°C) by peltier cooler. The result shows that the highest thermal conductivity value for all samples achieved at 35 °C. At 35 °C, the thermal conductivity ofhempe fibre is 0.2297 W/mK, luffa fibre is 0.0459 W/mK and pineapple fibre is 0.1746 W/mK. So that it is obtained that the cooling pad in hempe fibre transfers heat greater than that of luffa fibre and pineapple fibre.
