EFFECT OF HEATSINK FIN AND THERMAL INSULATORS ON OUTPUT OF THERMOELECTRIC POWER OF HEAT OF MOTORCYCLE EXHAUST GAS

Abstract

Thermoelectric can be utilized to convert exhaust heat into electricity. This study aims to determine the effect of heatsink height and thermal insulation on electric power generated from thermal powered thermoelectric plants. This research is using an experimental method. The technically of data analysis is descriptive comparative. In this research were used 10 mm, 20 mm, and 30 mm heatsink fin. Thermal insulator materials are glass wool and aluminum foil. Electrical power obtained from multiplication of electrical voltage and electric current. The data analysis was indicated the increasing electrical power with increasing heatsink fin height. The higher power is accomplished by using heatsink fin 30mm at 0.56-watt power output, and the smaller power is obtained by using heatsink fin 10mm at 0.32-watt power output. The results of thermal insulation testing indicate that there is an increase in electrical power when the use of thermal insulator. Data analysis were reported the most significant strength is obtained on the use of 30 mm heatsink with an isolator of 0.76 watts, and the smallest power is obtained on the use of high heatsink 10 mm without thermal insulator is 0.32 watts. The results of this study indicate that the heatsink fins height and thermal insulators affect the power generated by thermoelectric power plants.
