Development of a Low-Cost Cooling Box Based on Thermoelectric Effect

Abstract

Among the well-established cooling method via thermoelectricity is Peltier effect. Often known as thermoelectric cooling, the cooling effect is achieved without the use of any refrigerant, and this holds several advantages for industrial applications. In this paper, the process of designing and testing of low-cost thermoelectric cooling box were addressed. The design process was elaborated and the main components in the system such as the Peltier module, fan, cooling box made from among others were detailed out. The developed cooling box was then tested experimentally in terms of cooling capabilities by using canned drinks as items to be cooled. It was found that the temperature reduction was notably fast and successfully provided cooling to the canned drinks. The low cost components and materials used suggests its economics and potentials to be used on the do-it-yourself (DIY) basis as a hobby as well as commercial use.
