THE PORTABLE PARABOLА-CYLINDRICAL SOLAR FOODSTUFFS HEATER

Development of a parabola-cylindrical solar heater designed for heating and cooking food using solar energy is presented in the study. The design consists of a reflector, as parabola-cylindrical lens and receiver as skewers for food. Reflector is made of flexible materials but also has an advantage - resistance to external influences. Simple mount design allows to collect the heater into the drawing tube, the weight of which doesn’t exceed three kilograms, making the device convenient for transportation and in use. This is a special device due to which it is possible to concentrate solar radiation in the desired point and to reach the necessary temperatures suitable for heating and cooking of foodstuffs. The heater comfortable design has been shown and calculation features of basic geometric parameters of the parabola-cylindrical solar heater are given. The comparison with existing prototypes is given.
