Abstract: Different types of solar cookers developed for cooking are box type and concentrator type solar cookers. A parabolic concentrator type solar cooker has a wide range of applications like baking, roasting and distillation due to its unique property of producing a practically higher temperature of nearly 250°C and hence, it provides inconvenience to the user due to high amount of glare. The main objective of the present study is to incline cylindrical heat transfer fluid column as a heat transfer medium. The thermal performance of a parabolic solar cooker depends on inclined heat exchanger system of mild steel tube of length 157.5 cm and an internal radius 2.07 cm with heat transfer fluid (oil) of density 1075 kg/m³. Experiments are conducted for cooking of food at a normal day. The results show that inclined convective heat exchanger system can be used for off-place cooking. The optimization of the system design parameters is under investigation.
