The present invention discloses a mirror-foldable photovoltaic and photo-thermal switching type light condensing device and a heat emission and power generation method thereof. The mirror-foldable photovoltaic-photo-thermal switching type light condensing device comprises a two-segment type cambered reflector, a photovoltaic cell assembly, a vacuum tube heat collector and a real-time tracking device. The mirror-foldable photovoltaic and photo-thermal switching type light condensing device is characterized in the photovoltaic and photo-thermal switching type light condensing device further comprises a reflector rotation shaft; the two-segment type cambered reflector includes an upper reflector segment and a lower reflector segment, wherein the upper reflector segment and the lower reflector segment are rotationally connected through the reflector rotation shaft; the vacuum tube heat collector is located above the photovoltaic cell assembly; and the photovoltaic cell assembly is located below the two-segment type cambered reflector. The invention also provides a heat emission or power generation method. The mirror-foldable photovoltaic and photo-thermal switching type light condensing device of the invention is simple in structure. According to the mirror-foldable photovoltaic and photo-thermal switching type light condensing device of the invention, switching can be realized through rotating the reflector, and the movement of complicated heat transfer pipelines or battery circuits is not involved, and therefore, the device has high system reliability; and light condensing parameters can be designed according to actual demands.
Description
technical field [0001] The invention relates to a solar energy concentrating device, in particular to a photovoltaic photothermal switching type concentrating device with a foldable mirror surface. Background technique [0002] The two technologies of photothermal power generation and photovoltaic power generation use different conversion forms of solar radiation energy respectively. Photothermal power generation technology converts light energy into heat energy, which is easy to store, but requires direct sunlight radiation, and its efficiency is greatly affected by regions and seasons; photovoltaic power generation technology directly converts light energy into electrical energy to generate direct current. Electric energy storage is difficult to realize, but it can utilize the full radiation of the sun, effectively generate electricity for a long time, and is less restricted by region and environment. [0003] From the above characteristics, it can be seen that solar ther...
