[0017] The cooling device is composed of a box body 13, a collector 19 arranged inside the box body 13, and a regulating valve assembly. A cavity 20 is arranged inside the collector 19. The top of the cavity 20 is connected to the heating box 7 through a first pipe 8. The bottom of the cavity 20 is connected to the pervaporation assembly 16 through a fourth pipe 18. A curved heat exchange pipe 25 is arranged behind the pervaporation assembly 16. The two ends of the heat exchange pipe 25 respectively penetrate the two side walls of the box body 1 and are installed with a first connector 30 and a second connector 21. The heat exchange pipe 25 is connected to the first external pipe 5 and the second external pipe 4 through the first connector 30 and the second connector 21. The outer side of the pervaporation assembly 16 is located in the box body 13 and liquid is placed therein. A square hole 28 is arranged on one side outer wall of the box body 13, and a connecting shell (2 9), a regulating valve assembly is placed in the connecting shell 29, and the regulating valve assembly part passes through the square hole 28 and is placed on the liquid in the box body 1; the air in the heating box 7 absorbs heat under the sunlight to form a low-pressure area, so that the liquid in the box body 13 evaporates into gas through the permeation evaporation assembly 16, taking away the heat in the liquid in the box body 13, and the wind entering from the air inlet 10 exchanges heat with the low-temperature liquid through the heat exchange pipe, and then exchanges heat with the air in the basement through the fin heat exchange tube 3, thereby reducing the temperature of the basement; and the evaporated gas enters the cavity 20, the heating box 7, the connecting pipe 9 in turn through the third pipe 2 and then enters the water storage tank 11, and re-condenses into liquid in the water storage tank 11. The regulating valve assembly is opened due to the change in the liquid level, and the liquid in the water storage tank 11 returns to the box body 13. When the liquid level returns to the original height, the regulating valve assembly is closed.

[0018] like Figure 3-4As shown, the regulating valve assembly consists of a float 26, a first lever 28, a second lever 27, a third lever 35, a gate 36 and a gate plate. The float 26 is placed on the liquid in the box body. The float 26, the vertical second lever 27, the horizontal first lever 28, the vertical third lever 35 and the gate plate are connected in sequence, wherein the second lever 27, the first lever 28 and the third lever 35 are movably connected. The gate 36 is arranged on the second pipeline 12, and the gate plate is installed in the gate 36 and is pulled up and down by the third lever 35 to control the opening or closing of the gate, thereby controlling the opening or closing of the second pipeline 12. One end of the horizontal first lever 28 is located in the box body 13, and the other end is located in the connecting shell 29 after passing through the square hole 28, and a fixed block 33 is arranged between the middle position of the horizontal first lever 28 and the square hole 28, the bottom of the fixed block 33 is fixed on the square hole 28, and the top of the fixed block 33 is connected to the first lever 28 through a fixed pulley 34.

[0019] The top of the box 13 is detachably mounted with a cover plate 14, and the top edge of the box 13 extends outward to form a circle of mounting edges with bolt holes, and bolts 23 are inserted into the bolt holes on the mounting edges to fix the cover plate 14, and a sealing gasket 24 is also arranged between the cover plate 14 and the box 15. Preferably, the heating box 7 is composed of a transparent shell 37 and a black cloth 39 arranged inside the transparent shell 37 , and the black cloth 39 absorbs heat so that a low-pressure area is formed inside the transparent shell 37 .

[0020] The pervaporation components 16 are at least three groups, and one end of a nut 17 is threadedly connected to the end of the fourth pipe 18 at the connection between the fourth pipe 18 and each group of pervaporation components 16, and the other end of the nut 17 is threadedly connected to the pervaporation component 16 to achieve a detachable connection between the fourth pipe 18 and the pervaporation component 16. A fixing seat 15 is also installed at the bottom of each pervaporation component 16 in the box 13 to fix the installed pervaporation component 16. The pervaporation component 16 is a membrane component, and the membrane in the membrane component has the characteristics of being air-permeable and water-impermeable.

[0021] The present invention has a simple overall structure and can generate high-temperature steam and low-temperature cold liquid under low-energy consumption conditions, thereby reducing energy consumption and use costs, and the heat energy inside the device can be fully utilized during the circulation process.

[0022] The working principle and process of the present invention are as follows: The pervaporation component is made of a membrane that is bonded together and has the characteristics of being breathable and impermeable (a conventional technology). The membrane component as a whole is sealed to the outside, while the inside allows liquid to flow. The sunlight irradiating the heating box causes a pressure difference between the connected heating box and the box body, that is, a pressure difference is formed inside and outside the pervaporation component (membrane component). The pressure difference causes part of the liquid to vaporize and pass through the gap in the membrane, thereby taking away the heat in the liquid. The wind entering from the air inlet exchanges heat with the low-temperature liquid through the heat exchange pipe, and then exchanges heat with the air in the basement through the finned heat exchange tube, thereby reducing the temperature of the basement.

[0023] The air in the heating box 7 absorbs heat from the sunlight and forms a low-pressure area. At this time, the liquid evaporates through the permeation evaporation assembly, from the fourth pipe 18 to the cavity 20, through the first pipe 8 to the heating box 7, and finally through the connecting pipe 9 to the water storage tank 11. The evaporated liquid will eventually condense into a liquid state in the water storage tank 11. At this time, the wind entering from the air inlet will exchange heat with the liquid when passing through the heat exchange pipe 25, and then exchange heat with the air in the basement through the finned heat exchange tube 3, and finally be discharged from the air outlet 6 through the first external pipe 5. Due to evaporation, the liquid level will drop, causing the buoy 26 to drop, driving the second lever 27 to pull the first lever 28, and then pulling the third lever 35 through the first lever 28, and finally opening the gate in the gate 36, and the liquid in the water storage tank 11 will flow back to the box body 1 again. After the liquid level rises, it will drive the gate in the gate 36 to close, so that the pipeline is closed.

Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
