The invention discloses a high-power concentrating photovoltaic thermal control device. The high-power concentrating photovoltaic thermal control device comprises a radiator and a water tank, whereina circulating pipeline arranged on the radiator is arranged inside the water tank, and heat exchange is carried out between a heat-carrying working medium in the circulating pipeline and water in thewater tank; the high-power concentrating photovoltaic thermal control device is characterized in that the radiator further comprises a heat absorption surface and a heat dissipation part, wherein theheat dissipation part is arranged on one side of the heat absorption surface, and a medium inlet and a medium outlet are formed in the heat dissipation part; the circulating pipeline is connected to the medium inlet and the medium outlet; and fins are arranged in the radiator and gaps formed by the adjacent fins are equal. The technical scheme provided by the invention is used for temperature control of a concentrating photovoltaic power generation battery; the high-power concentrating photovoltaic thermal control device is reasonable in structure, and the heat-carrying working medium is usedfor taking away heat from the heat absorbing surface so as to achieve the purpose of temperature control, so that the service life of the battery is guaranteed, and the reliability and the efficiencyof concentrating photovoltaic power generation are improved; and in addition, the heat taken away by the heat-carrying working medium is stored in water in the water tank, so that waste is reduced, and the utilization rate of energy is improved.
Description
technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a high-power concentrating photovoltaic thermal control device. Background technique [0002] Concentrating photovoltaics refers to the technology of directly converting concentrated sunlight into electrical energy through photovoltaic cells with high conversion efficiency. [0003] Concentrating photovoltaic technology gathers scattered solar energy through optical methods to realize high temperature and high heat flow solar energy utilization. For example, by concentrating light on a Fresnel plane, the concentration of solar light energy with a geometric magnification of more than 1000 times can be realized. At this time, the temperature at the spot reaches or exceeds 1000°C, and the heat flux reaches 100W / cm 2 above. Three-junction concentrated photovoltaic power generation is a kind of concentrated photovoltaic power generation, which can obtain a photoelectric ...
