Development of Heat Extraction System for Automobile Application using Peltier Devices

This paper proposes a development of heat extraction system using Peltier devices to extract the heat trapped inside cars. The heat tremendously increases, when exposed to direct sunlight for extended hours during parking time. A test was conducted and the result showed that at 1.50 pm, the temperature inside the car reached more than 50°C. A heat extraction system uses a solar panel, battery and charge controller as a power supply to the system, Peltier modules and fans as cooling system elements and temperature controller to automatically regulate temperature inside the car. The entire cooling system is assembled and tested on a prototype made from polypropylene and acrylic material. It is found that the heat extraction system is capable of maintaining the temperature inside the prototype effectively in the range of 31.74°C to 35.64°C.
