  • Publication number: 20160223226
    Abstract: A solar power generation system according to the present invention comprises a heat pipe arranged so as to come into close contact with an absorption module, for absorbing heat from the absorption module and directly transferring heat to a heat conversion electricity generator, and thereby has the advantages of rendering the system compact by simplifying a heat transfer structure and more effectively transferring heat by increasing contact surface area with the absorption module. Also, ample heat storage space is secured by forming the heat pipe to have a larger volume (heat capacity) than an absorption heat pipe in the absorption module so that an ample heat source can be provided by the heat conversion electricity generator, even during weather conditions when solar radiation can fluctuate suddenly, thereby allowing more stable and efficient operation of the system.

  • Publication number: 20150357545
    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.
