Abstract :
Thermoelectric is a component that can produce electrical voltage due to
the temperature difference between the hot side and the cold side given to the
thermoelectric module. In this study, the number of thermoelectric modules used
were eight installed in series and capable of producing a maximum voltage of
48.2 to 50 Vdc with hot water temperature of 85.3ºC - 90.1 and cold water
temperature of 8.8ºC. From the results of testing the resilience of the voltage that
is produced by the modules Thermoelectric to turn the load LEDs, motors and HP
charger is for 30 minutes with temperatures that are increasingly decreasing .
The load variations used are in the form of LEDs, motorcycles and mobile phone
chargers . The results of the total power analysis in the endurance test of the
largest thermoelectric module voltage is at a hot temperature of 90.1 ºC and a
cold temperature of 8.8 ºC with a time of 4.40 is 4 Watt with an error value of
32.89%, and the results of the total power analysis on the resistance test of
voltage thermoelectric module is the smallest on the hot temperature of 53.3 ºC
and 20 ºC cooler temperatures with a time of 5:10 was 0.21 Watt with an error
value of 93.0%.
