Design and realization of a box type solar cooker with thermal storage dedicated to the rural regions of the oriental district

In this article, the work presented concerns the design and the simulation of the operation and the experimentation of a solar cooker, of the box type with three reflectors. in order to improve the efficiency of the cooker, we integrated the heat storage of the temperature with the salt placed at the base of the cooker. the first obtained results show a thermal resistance of the cooker of the order 0.51k.w^-1, under ansolar radiation of 1000 w/m^2, temperatures, powers and efficiencies respectively reach 140°c, 225.49w and 93%. regarding the temperature storage, we showed that after one hour without solar radiation, the storage ensures the maintenance of the temperature of the order 40% of the value with illumination. the comparison between the experimental results and those simulated shows a good agreement and consequently the validation of the operation and the insulation of the cooker proposed during this work.
