An Experimental Design and Analysis of Portable USB Powered Thermo Electric Cooler

Refrigerators are energy consuming home appliances and for this reason researchers are performed to enhance performance work of the refrigeration systems. Most of research work done so far deals with an objective of low energy consumption and refrigeration enchantment. Thermoelectric refrigeration is one of the method to produce refrigeration effect. This project demonstrates how far thermoelectric refrigeration can be modified to produce refrigeration effect with low power input and high cooling effect. In this project a portable thermoelectric (Peltier) cooler is designed and fabricated for multipurpose use (Like beverage cooling, water cooling, and milk storage). It is operated on USB with low power, it is portable in nature, compact in seize. This project carries out cooling effect analysis, FEA steady state heat transfer analysis in ANSYS software on PET water bottle material with heat transfer plates, thermal insulation jacket. Power consumption of TEC device is experimented and calculated with practical model on DC-DC boost converter.
