  • Patent number: 10256390
    Abstract: A solar power generation system according to the present invention comprises heat pipes which are arranged radially on the outer peripheral surface of an absorber to increase heat transfer effectiveness between the absorber and the heat pipes, thereby improving heat transfer efficiency. Also, the solar power generation system has the advantage of operating the system more stably and efficiently even in suddenly changing weather conditions, due to the improved heat transfer efficiency and capability to store heat for a specific amount of time. In addition, when the heat pipes are extrapolated onto the absorber, heat can be transferred more effectively by increasing contact surface area with between the absorber and the heat pipes. Furthermore, heat can be transferred more effectively by increasing the contact surface area by coupling the heat pipes to a heat exchange portion through a block-coupling technique.
