Abstract

In the past decade,there has been significant development in green technology which using energy harvesting system to power on electronic devices instead of using batteries.In this paper,the concept of using thermoelectric generator (TEGs) for converting the waste heat energy exerted from laptop into electrical energy is presented.The main focus of this project is to build an autonomous cooling system for laptop using TEGs whereas the speed of the cooling fan can be controlled by a microcontroller based on the temperature detected by temperature sensor.In addition,the microcontroller is powered on by the energy harvested from TEGs.The system with two voltage booster and supercapacitor has been designed for the supply of microcontroller.This work considers the laptop waste heat as the heat source,4 thermoelectric generator (TEGs) attach with heat sink is placed under the laptop to generate electrical energy over time.The TEGs was tested with a laptop, it is able to produce 110mV by having 3ºC temperature differences. The primary booster manages to boost up the harvested energy to usable voltage level which is 3.3V and store it into a supercapacitor.The secondary voltage booster is able to boost up the voltage from 3.3V to 5V which is required to turn on microcontroller.The microcontroller can operate for about 30 seconds to control the cooling system if the capacitor is fully charged.Primary voltage booster will charge the supercapacitor overtime and roughly require 20 hours to charge the supercapacitor to 3.3V.
