i-Magarctic: an intelligent thermoelectric cooling system with anti-condensation control for smartphones

The increasing use of smartphones for high-intensity applications such as mobile gaming has resulted in significant thermal management challenges, affecting device performance and reliability. This project introduces i-MagArctic, an intelligent cooling system that integrates thermoelectric technology with liquid cooling and incorporates an anti-condensation mechanism based on dew point control. The system was evaluated through a 20-minute experimental test, with temperature data recorded at two-minute intervals. The analysis focused on key parameters including peak temperature, average temperature, heating rate, thermal stability, and cooling efficiency. The results indicate that i-MagArctic successfully reduced the smartphone peak temperature from 44°C to 35.9°C and the battery temperature from 41°C to 32.3°C. Additionally, the heating rate was significantly reduced, and temperature stability improved based on lower standard deviation values. The system achieved a cooling efficiency of 18.41% for the smartphone and 21.2% for the battery. Overall, i-MagArctic demonstrates strong effectiveness in managing smartphone thermal performance and shows high potential for commercialization as a mobile gaming accessory.
