NOVELTY - The collecting device has a solar light guiding device that is connected with a solar energy absorbing device. The solar energy absorption device is fixed on a solar energy positioning tracking reflection device. The solar light guide device includes a condenser lens (13). The focusing point of the condenser lens is rotatably connected to one end of a light guide fiber (11). The other end of the light guide optical fiber is fixedly connected with the solar energy absorption device. A solar panel (14) is also provided at the connection between the condenser lens and the light guide optical fiber. The nano-magnetic material is a composite magnetic material formed by wrapping iron oxide on the surface of graphene. USE - Magnetic fluid zero-carbon light-guiding solar heat collecting device. ADVANTAGE - The light guide optical fiber goes deep into the heat collecting pipe, and on the basis of the existing direct absorption type solar heat collecting device, sunlight which is not utilized on the side surface of the solar absorbing device can be collected, and the sunlight is guided into the middle area with the slower temperature rise through the light guiding optical fiber, so that the technical problem of slow internal temperature rise is solved. The device is simple to manufacture and low in cost. The area where the zero carbon leading side is not utilized is introduced into the temperature increasing slow area, so that the utilization rate of solar energy and the heat collecting efficiency are improved, the problems of low heat transmission efficiency, long heating time caused by uneven heating do not exist, and the device can adapt to different scenes such as families and factories.
