Box Type Solar Cooker Components

Role in improving performance for society acceptance

Abstract

Box Cooker Consists of inside box and outside box in between the box thermal insulation. By reducing surface area inner box, the temperature inside box increases. The inner box is of shape compound paraboloid cross section in square (two parabolas focal axis is perpendicular). This shape useful in reflect/deflect sun ray/radiations and surface heating of cooking vessel in addition to top lid heating. This shape useful in receiving vertical rays of sun noon period. Approximate curved reflector made from half pyramid (two sides of pyramid) tied to outer box with flexible rope to with stand wind load and for tilt adjustment also. It covers 2 sides of box and reflects sun light in to box cooker through top cover glasses in inclined portion of sun light. Reflector used is mirror segments. 14nos. mirror segments reflections are overlaps and higher temperatures generates to boil/frying/drying food. This reflector tracks sun. Only at noon to be rotated to once in a day for tracking. This ensures improved performance of cooker and acceptance solar cooking in society increases.
