step three, automatically collecting dew in the dry area: the aluminum dew-collecting panel is oxidized in the air to form a layer of aluminum oxide, the air is isolated, the aluminum dew-collecting panel is prevented from being corroded, the temperature of the aluminum dew-collecting panel is rapidly reduced to be below the ambient temperature along with the reduction of the ambient temperature, water vapor transmitted in the air is received, the water vapor is rapidly condensed into water drops on the surface of a bulge (10) coated with a super-hydrophilic coating on the aluminum dew-collecting panel after the bulge (10) receives the water vapor transmitted in the received air, the water drops roll down to a diversion trench (12) coated with the super-hydrophobic coating through a non-bulge area coated with the super-hydrophobic coating on the aluminum dew-collecting panel along with the increase of the water drops, and then the water drops into a confluence pipe (1) after flowing into a water inlet hole (11) along the slope of the diversion trench (12);
step four, dew utilization: dew automatically collected on each aluminum dew collection panel flows into a collecting pipe (1) uniformly and then enters a utilization mechanism through the collecting pipe (1), the utilization mechanism comprises a water storage tank (6) and a reducer pipe (4) installed at the bottom end of the collecting pipe (1), one end, far away from the collecting pipe (1), of the reducer pipe (4) is communicated with the water storage tank (6) through a hose (5), the bottom of the water storage tank (6) is provided with a water pipe (8), and a water valve (7) is installed on the water pipe (8);
dew collected in the water storage tanks (6) is converged into the reservoir to be utilized through the water pipes (8);
or the dew collected in the plurality of water storage tanks (6) is directly discharged and utilized through the water pipes (8).
10. The method of claim 9, wherein: two aluminium system collection dew panels that set up mutually oppositely in the drainage that condenses pass through the metal glue bonding.
