Design and implementation of Novel Solar Cooker

Abstract

This work is centered on the design and fabrication of a solar cooker for routine household cooking device. It is a modification of a convectional flat plate collector solar cooker with the use of plane reflectors to increase the energy input to the collector and improving its efficiency. The main features of the cooker box are its rectangular shape, the double-glazing and the adjusting mechanism for the two reflectors at the sides. The solar cooker design is fairly simple and its fabrication was accomplished using inexpensive and locally available materials that satisfy the necessary requirements. The solar cooker comprises of the cooking chamber, reflectors, aluminum foil, aluminum absorber plate, double glazing. The cooker box is made of plywood, silvered glass was selected as the reflector surface, and transparent glass was used for glazing while aluminum sheet was selected as the absorber plate. The solar cooker was tested and the results yielded a maximum of 97oC for the cooker chamber and the efficiency of the solar cooker was 76.74%.
