This study aims to design, develop, and analyze the performance of a portable micro-cooling cup that uses a Peltier thermoelectric module for efficient beverage cooling. The cooling cup provides a practical, low-energy alternative for keeping drinks cool without refrigeration systems. The cooling cup uses the Peltier module, which generates a temperature differential when an electric current flows through, to successfully lower the beverage temperature in minutes. The Peltier module, a heat sink, a fan for better heat dissipation, and a rechargeable power source for portability are all essential components. Experimental results show that the cooling cup may reduce liquid temperature by up to 15°C from the starting temperature for up to 10 minutes under ideal conditions. This technology is ideal for various scenarios, including outdoor activities and travel, where access to traditional cooling appliances is restricted. The study also looks into energy economy, durability, and user ease, emphasizing the promise of thermoelectric technology for small-scale, portable cooling systems. This portable cooling innovation has the potential for personal and commercial applications, meeting the growing demand for easy beverage chilling on the go.
