A linear Fresnel concentrating power-generation system is favored by the market because of its small windward area and high land-occupation rate. However, the further reduction of the construction cost of the concentrating system is an ongoing problem. Therefore, we include several thin heat pipes instead of a crude heat pipe to solve this problem so that the total opening and primary reflector widths are increased to 1118.79 and 831.81 mm, respectively, for the compound parabolic condenser (CPC). Additionally, we study the light-gathering system for this design idea and find a CPC opening half-angle of 45°. For a working time of 6 h, the light that is incident on the primary mirror field is reflected into the CPC, and the rate is above 75%. Additionally, the instantaneous rate of light entry into the CPC is more than 75%. The experimental results showed that the optical efficiency reached 61% at noon in summer/sunny weather.
