Radiation device for reducing indoor air humidity

[0015] Such as Figure 1-4 As shown, the radiation device body 1 includes a cold water circulation system 2, a radiant plate 3, and an insulation layer 4. The radiant plate 3 made of copper or aluminum is a rectangular flat plate with a thickness of 1 to 2 mm. The radiant plate 3 is different from the cold water circulation system 2. There is a superhydrophobic substrate 5 on one side of the superhydrophobic substrate 5. Several hydrophobic microgrooves 6 with a width of 0.1~10mm and a depth of 0.1~5mm are evenly distributed on the superhydrophobic substrate 5. The angle between the hydrophobic microgrooves 6 is 0~90° The needle-like hydrophilic bionic structure 7 with a length of 0.1~30mm is arranged randomly and disorderly or equidistantly. The hydrophilic region and super-hydrophobic region are organically combined, and the needle-like hydrophilic bionic structure 7 can quickly trap the air. Water vapor molecules reduce the humidity of indoor air. Equally spaced arrangement includes two ways: in-line and crossed. The needle-shaped hydrophilic bionic structure 7 is made of copper, carbon steel, stainless steel, aluminum or nanoporous ceramic materials. The gap between the cold water circulation system 2 and the radiation plate 3 is provided with a metal fin 11 with a thickness of 2 to 3 mm, and the metal fin 11 is made of copper or aluminum. The bottom of the radiation device body 1 is provided with a condensed water receiving pan 12, and the condensing water receiving pan 12 is connected with a condensate drain pipe 13 to discharge the condensed water generated on the surface of the radiant panel 3. The superhydrophobic substrate 5 formed after the surface of the radiation plate 3 is modified. The superhydrophobic substrate 5 has a micro-nano binary surface structure and the rolling angle is less than 6°. The rolling resistance of the superhydrophobic substrate 5 surface is small, which is conducive to the rolling of droplets. When condensed water is generated on the surface of the radiant panel 3, it is easy to fall off from the surface of the radiant panel 3, which is beneficial to the discharge of condensate droplets.

[0016] Such as Figure 5 The cold water circulation system 2 includes a number of water supply branch pipes 8, a water supply main pipe 9 and a return water main pipe 10. The water supply branch pipe 8 is connected to the water supply main pipe 9 and the return water main pipe 10 respectively. The water supply branch pipe 8 is arranged in parallel, and the distance between the water supply branch pipes 8 is 30 ~90mm. The equivalent outer diameter of the water supply branch pipe 8 is 8-20 mm, the equivalent outer diameter of the water supply main pipe 9 is 15-25 mm, and the equivalent outer diameter of the return water main pipe 10 is 15-25 mm. The cold water produced by the water chiller flows through the circulating pipe to reduce the surface temperature of the metal fin 11 and the radiant plate 3 to form a cold radiant surface. The thermal insulation material restricts the heat transfer direction of the radiant panel 3, so that more cold energy is transferred to the indoor working area.
