In this paper linear Fresnel reflector solar collector system was studied. Based on the principle of geometrical optics, the mirror field layout and compound parabolic collector were calculated. The mechanical structure of the system was designed to reduce end loss energy, and the linear Fresnel reflector collector device was made. The solar collecting performance was tested. The experimental results show that the maximum temperature of the heat transfer oil is 176.2°C with the concentration ratio of 9 times. The average instantaneous efficiency of the system is 53%, which achieves a good solar collecting performance.
