The results of the thermal behavior and exergy efficiency of a prototype of a parabolic solar cooker are shown. The design and construction of the prototype consider aspects that have not been addressed in other devices of the same nature, such as easy construction and low cost. The results of the temperature reached approximately 96 ° C can be useful for use in domestic applications of cooking and heating food in homes. The evaluation of the efficiencies both first and second law show values less than 45% and 5% respectively and these generate the possibility of carrying out improvements in the solar cooker, which would allow significant improvements to be made in the times required for cooking. and food heating. If the construction-cost relationship of the device is considered, the analysis presented in this work can contribute to its promotion and use in the society that demands alternatives to current and future energy problems.
