The invention discloses a
solar light condensed heat collector and a method for designing the
solar light condensed heat collector. A
paraboloid main reflector is arranged. A vacuum heat collecting
pipe is installed on the symmetrical axis of the cross section of the
paraboloid main reflector and on the inner side of the
focal line of the
paraboloid main reflector. An even light reflector is installed on the outer side of the
focal line of the paraboloid main reflector. The even light reflector and an opening of the paraboloid main reflector are oppositely arranged and fixedly connected. According to the
solar light condensed heat collector and the method for designing the solar light condensed heat collector, the vacuum heat collecting
pipe is arranged below the position of the
focal line of the paraboloid main reflector, the even light reflector is additionally arranged and opposite to the opening of the paraboloid main reflector, solar
radiation energy can be distributed at the bottom and the top of a heat absorption
pipe,
solar energy flux density distribution on the wall face of the heat absorption pipe is homogenized, the
temperature gradient and the highest temperature of the wall face of the heat absorption pipe are reduced, a series of problems caused by uneven
energy flux density can be avoided from the source, and safety performance of the vacuum heat collecting pipe is improved.
