A mathematical model of a box-type solar cooker, accounting for the solar energy input and internal heat exchange among the pot, walls, top cover and air has been developed and reported earlier. The model considers the variable sun angle and intensity, box and reflector orientation, heat losses, cooking time, wind, and other variables. In the present application of the model, an extended surface, or fin, is attached to the pot. The fin acts to increase the direct solar radiation to the pot-fin system as well as add surface area for convection from the air in the box. Results for specific geometries of fins with variable length and thickness show that the food temperatures can be appreciably increased with the finned pot.
