SOLAR COLLECTOR USING A PARABOLIC REFLECTION PLATE

摘要

A solar collector using a parabolic reflecting plate is provided to realize high heat conversion efficiency by immediately converting light concentrated on the interior of a cylindrical light receiving part into heat, and to enable a simple structure without an additional heat collecting device or system. A solar collector(100) using a parabolic reflecting plate includes a reflecting plate(110) and a cylindrical light receiving part(120). The reflecting plate has a parabolic reflecting surface and a long cylinder which is cut at a predetermined portion thereof, thus having a linear focal line. The cylindrical light receiving part is located in front of the reflecting plate, and has a cylindrical space therein. Further, the cylindrical light receiving part has an opening which is aligned with the focal line of the reflecting plate in the shape of a narrow straight line along the focal line of the reflecting plate. The cylindrical light receiving part is configured such that the central point of the inner circumference is positioned between the central point of the outer circumference and the focal line of the reflecting plate.
