The upper part of the shell is provided with a transparent toughened glass cover plate 1, and the front surface of the shell is provided with uneven holes on the toughened glass plate 2. The inside of the shell is provided with a fan 3, a flow equalizing plate 4 and a single-row evaporator 5 coated with a chromium atom solar selective absorption coating. A flow equalizing plate 4 with the width of the diameter of the fan is arranged between the fan 3 and a single-row evaporator 5 coated with the chromium atom solar selective absorption coating.
When the solar/air heat pump operates, the fan 3 blows air to the single-row evaporator 5 coated with the chromium atom solar selective absorption coating, the whole single-row evaporator 5 coated with the chromium atom solar selective absorption coating is positioned on the positive pressure side of the fan 3, because the air flow of the fan 3 is unevenly distributed on the whole single-row evaporator 5 coated with the chromium atom solar selective absorption coating, the flow equalizing plate 4 is arranged in front of the single-row evaporator 5 coated with the chromium atom solar selective absorption coating to increase resistance and reduce uneven air flow, namely, the air flow is equalized from the fan 3 to the flow equalizing plate 4, and then exchanges heat through the single-row evaporator 5 coated with the chromium atom solar selective absorption coating, and toughened glass plates 2 are discharged from uneven holes. The toughened glass plate 2 is uniformly perforated, and the flow equalization is carried out through the nonuniform perforation again, so that the aim of uniform air flow distribution is fulfilled.
Solar energy passes through the transparent toughened glass cover plate 1 and the uneven toughened glass plate 2 that has opened a hole, shines and is absorbed by its selective absorption film on the single-row evaporator 5 who scribbles chromium atom solar energy selective absorption coating, increases the evaporimeter heat exchange efficiency.

The light transmittance reaches 90%, and the density is about 2400-2800 kg/m3And has stable physical and chemical properties and high mechanical strength. When the unit operates, sunlight can penetrate through the upper transparent cover plate and the front transparent cover plate to irradiate the surface of the evaporator and is absorbed by the surface solar selective absorption coating, so that the surface temperature of the evaporator is increased, and the heat exchange efficiency of the evaporator is improved.
The solar selective absorption film is a chromium atomic lamination heat absorption heating film, and in engineering practice, an evaporator fin is made of Al alloy, and the maximum thickness of the evaporator fin is 0.2 mm. If the thickness of the fins is too large, the heat transfer efficiency of the fins is reduced, and the excessively narrow flow passage size may cause frosting of the evaporator and deteriorate the heat transfer. Therefore, the fin thickness is often controlled to be within 0.2 mm. The atomic lamination heat absorption heating film has a more compact structure, can keep a better form in mechanical scraping and pulling, and is more beneficial to the normal operation of a solar/air energy evaporation heat collector. The chromium atomic layer deposition heat absorption heating film can reach 97% of absorptivity and 6% of emissivity.
