The Design of Portable Beverages Can Cooler using Peltier Effect

Abstract

The objective of this portable beverage can cooler / warmer project is to design a compartment which can heat or cool the item as required. The mechanism used for this cooling and heating is the Peltier Effect Device whereby a normal refrigerant for example gases or water as the thermal media is not used in the design. Peltier Effect Device are made of N and P type semiconductors that are joined together by metal contact to form a junction that can perform cooling on one side while heating on the other side. The literature review aids better understanding of the project title. Analysis stage helps in problem solving thus decision making process. A glass of water was place inside the compartment to test the performance of the device at the room temperature of 27 °. The glass is place in between 1-2 minutes. The water is then measured by the temperature sensor. The Peltier Effect Device at the cold part of compartment is put on a heat sink to dissipate the heat transfer by the Peltier Effect Device. Between the Peltier Device and heat sink, thermal paste is applied evenly to help removing the heat faster. Then, a 12V fan is placed below the heat sink. This prototype can cool down to 10 ° for cooling and 30 ° for heating in 2 minutes.
