Problems solved by technology
Due to the long pipeline of the heat collecting vacuum tube, the energy loss is relatively large, so that the operating temperature of the internal heat transfer oil heat transfer medium can only reach about 400 °C, and can only stay in the middle temperature stage, thus limiting the use of solar trough thermal power generation efficiency

The invention discloses a solar strip-type parallel light ultrathin condenser. The condenser comprises a strip-type converging lens board, a strip-type diverging lens board, a first reflector, i reflectors, p reflectors and frames, wherein corresponding 2n-numbered strip-type converging lenses and strip-type diverging lenses are arranged on the strip-type converging lens board and the strip-type diverging lens board; output reflecting surfaces are arranged on the first reflector; output reflecting surfaces and normal reflecting surfaces are arranged on the i reflectors; normal reflecting surfaces are arranged on the p reflectors; the incident sunlight is focused by the strip-type converging lenses and then passes through the strip-type diverging lenses to form lens condensed parallel light; reflection light is formed through the normal reflecting surfaces; and then condensed output light is formed through the output reflecting surfaces. The device has the following beneficial effects that: the incident sunlight on the surface can be completely converted to condensed light; the condensed output light and the incident sunlight are parallel and are propagated in the same direction; the condensation region is behind the condenser; the condensation distance is short; the processing difficulty is low; the condensed light radiation efficiency is high; and the condensed light is uniform in radiation and distribution.
Description
technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to an optical device for concentrating sunlight. Background technique [0002] Solar energy is a clean and pollution-free renewable energy, inexhaustible and inexhaustible. Fully exploiting solar energy can not only save the increasingly depleted conventional energy, alleviate the severe shortage of resources, but also reduce pollution and protect human beings. ecological environment for survival. [0003] Among the many solar energy utilization technologies, the most common are solar photovoltaic power generation, solar thermal power generation, and solar water heaters. At present, in solar photovoltaic power generation, most of them use the photovoltaic power generation technology of silicon cells, and silicon cells only convert about 15% of the solar energy reaching the ground into electrical energy, and the overall utilization efficiency of solar energy is stil...
