Apparatus for collecting water from air by solar semiconductor refrigeration dewfall method

The utility model relates to an apparatus for collecting water by making use of a solar semiconductor to refrigerate in a dew condensing mode. The utility model comprises a heat regenerator, a heat insulating layer, a water condensing chamber, a water collector, a water discharging valve, a radiating fin and a blower thereof, a two-dimensional rotary stage, a solar panel, a cold board, a blower, a thermopile, a temperature and humidity sensor and a single-chip microcomputer system, wherein, the solar panel is fixed on the rotary stage to cause the solar panel to be perpendicular to sunlight all the time, and the utilization rate of solar energy is improved. The utility model is provided with the board-type hear regenerator to improve the water collecting rate. The solar panel supplies power for the semiconductor to refrigerate, the blower is used for causing natural air to pass the cold board continuously, and water vapor in the air is condensed into water drops which pass through the water condensing chamber to flow into the water collector to realize refrigeration, temperature drop, water condensation and water collection. The utility model has the advantages of small size, light weight, high water collecting rate and convenient carrying.
