Mechanical engineering students of Rayat-Bahra University (RBU) have developed a low-cost roof cooling system for cars in hot weather conditions.

Tejinder Singh, Vipulove Kaushal and Sachin Ranakoti, under the guidance of Prof Sanjeev Dhama, developed the system using 2UV polycarbonate sheets in the rooftop structure that prevent the rise in temperature inside the car due to direct sunlight falling on its windowpanes. Owing to the high heat dissipation property of the sheets, these act as a barrier between the direct sunlight and the car rooftop, thus preventing the greenhouse effect. Moreover, the rooftop structure is made according to the shape of the car that helps avoid the problems of air drag. The material used in the rooftop structure is very light in weight and hence, does not have any appreciable effect on the efficiency of the car.

Prof Dhama, project coordinator, said polycarbonate sheets were a good electrical insulator and have heat-resistant and flame-retardant properties.

RBU vice-chancellor SK Bansal appreciated the efforts put in by the students.
