【 摘 要 】

In this research we design Solar radiation is collected by a combination of Parabolic length 6m and Diameter 3m. So the Aperture area will be 15.6m2. aluminum Foil Used to reverse sunlight because characterized by high reflexivity (90)% . using a manual moving system to follow the sun solar radiation. This type of solar concentrator is widely used in solar energy . The oil was used to pass in a copper pipe were used to receive heat, long 160m and a diameter (0.48)mm was rolled on a tube of iron with a diameter (6)cm, a number of rolls is 561 roll which was painted in black .Hot oil moves by pump to a thermal transformer that evaporates the water. The system was installed At coordinates (Iraq - Tikrit (°36 ' 34) (43'45) in the months of February, March and April. It is the time of the spring and these months characterized by moderate temperature. The results showed the efficiency of converting solar radiation into thermal energy stored in oil(54.7). system was tested in the spring months and was the highest temperature reached by the outlet oil (176) The system has stability in the temperature difference of the oil inlet and outlet. The highest thermal capacity was recorded in a month (march) With a value of(8469 ) The highest value of the work as a function of pressure (2) bar.
