Title: SOLAR ENERGY RECEIVER AND SOLAR-POWERED WATER HEATER
Abstract:
Provided are a solar energy receiver and a solar-powered water heater, the solar energy receiver comprising: a photovoltaic cell chip (1), a base (2) provided with the photovoltaic cell chip (1), a condensing system (3) arranged along the front end of the photovoltaic cell chip (1) in the direction of radiation of light, and a heat-dissipating auxiliary member (4) arranged around the photovoltaic cell chip (1); the heat-dissipating auxiliary member (4) extends in the direction of the condensing system (3) at a predetermined distance from the base (2) so as to separate the space surrounding the photovoltaic cell chip (1) into a first space (51) near the photovoltaic cell chip (1) and a second space (52) away from the photovoltaic cell chip (1); the heat-dissipating auxiliary member (4) is provided with a compact opening so that the first space (51) and second space (52) are in communication with each other. if the temperature of the air in the first space (51) rises due to the condensation of light on the photovoltaic cell chip (1), then a temperature difference is formed between the first space (51) and the second space (52), and an air flow between the first space (51) and the second space (52) is produced; the heat in the first space (51) is thus removed by the air flow, achieving good auxiliary heat dissipation performance.
