[0002] The scarcity of water resources in desert areas has greatly restricted the development of afforestation. Desert water supply devices can alleviate this problem. Functionally, the surface prepared by traditional desert water supply devices has the characteristic of isotropy at ambient temperature, which greatly reduces the water collection efficiency in desert areas. Summary of the Invention

[0003] The problem of difficulty in obtaining water in the desert is solved by intermittently utilizing solar energy and condensation (frost) to obtain a higher water collection efficiency. The present invention provides a hydrophobic / super-lubricating interphase surface for enhanced refrigeration and a high-efficiency condensing device.

[0004] The technical solution adopted by the present invention is: a hydrophobic / super-lubricating interphase surface and high-efficiency condensing device for enhancing refrigeration, comprising a reversible water collection interlayer device, a water storage device arranged below the water collection interlayer device, and a rotating device for driving the reversal of the water collection interlayer device;

[0005] The water collection interlayer device comprises a hydrophobic copper plate / silicone oil interphase layer, a PDMS layer, a semiconductor refrigeration plate layer and a solar cell plate layer, which are arranged in sequence from top to bottom;

[0006] The hydrophobic copper plate / silicone oil interphase layer is flat as a whole, with the length direction of the hydrophobic copper plate / silicone oil interphase layer as the x-axis direction and the width direction of the hydrophobic copper plate / silicone oil interphase layer as the y-axis direction; the hydrophobic copper plate / silicone oil interphase layer includes multiple hydrophobic copper plates, a single hydrophobic copper plate extends along the x-axis direction, and multiple hydrophobic copper plates are spaced along the y-axis direction; silicone oil is dripped between adjacent hydrophobic copper plates to form a silicone oil strip-shaped hydrophilic area;

[0007] The bottom surface of the hydrophobic copper plate / silicone oil interphase layer is coated with a PDMS layer to connect the hydrophobic copper plate / silicone oil interphase layer and the semiconductor refrigeration plate layer, and the PDMS layer wraps the semiconductor refrigeration plate layer and the wires of the semiconductor refrigeration plate layer;

[0008] The semiconductor refrigeration plate layer is composed of multiple semiconductor refrigeration plates, and the cold ends of the multiple semiconductor refrigeration plates are all arranged upward; the positive poles of the multiple semiconductor refrigeration plates are connected in parallel and connected to the positive pole of the solar cell panel layer, and the negative poles of the multiple semiconductor refrigeration plates are connected in parallel and connected to the negative pole of the solar cell panel layer through a switch structure;

[0009] The rotating device includes a connecting structure and a driving motor. The connecting structure includes a crosshead and a cross sleeve. The two crossheads are respectively located on both sides of the semiconductor refrigeration plate layer along the y-axis direction; the cross sleeve is provided with a cross slot hole that cooperates with the crosshead, and the cross sleeve is provided with four connecting columns on the side surface away from the semiconductor refrigeration plate layer. The four connecting columns are connected to a shaft sleeve through a connecting rod, and the shaft sleeve is used to be fixedly connected to the output shaft of the driving motor; the driving motor drives the water collection layer device to rotate around the y-axis to switch the upper and lower positions of the hydrophobic copper plate / silicone oil interphase layer and the solar cell panel layer; when the hydrophobic copper plate / silicone oil interphase layer is located at the top, the driving motor can keep the hydrophobic copper plate / silicone oil interphase layer in an inclined state with one end lower and the other end higher in the x-axis direction;

[0010] The water storage device has a cavity. When the hydrophobic copper plate / silicone oil interphase layer remains in an inclined state, the water storage device is connected to the lower end of the hydrophobic copper plate / silicone oil interphase layer to collect condensed water flowing down from the hydrophobic copper plate / silicone oil interphase layer.

[0011] Furthermore, the switch structure includes two contacts, a long wire and a plastic switch trigger. One end of the long wire is connected to the negative pole of multiple semiconductor refrigeration plates, and the other end of the long wire is provided with a contact, and the other contact is connected to the negative pole of the solar cell panel layer; a plastic switch trigger is provided on the side of the long wire, and the plastic switch trigger can stretch or shrink the long wire to connect or disconnect the two contacts.

[0012] Furthermore, the semiconductor refrigeration panel layer and the solar cell panel layer are bonded together using silicone as an adhesive.

[0013] Furthermore, the hydrophobic copper plate is made by soaking the copper plate in fluorosilane for hydrophobic modification.

[0014] Furthermore, a second guide microgroove is provided at the lower end of the hydrophobic copper plate / silicone oil interphase layer along the x-axis direction, and the second guide microgroove extends along the y-axis direction. The second guide microgroove is used to collect condensed water flowing out of the hydrophobic copper plate / silicone oil interphase layer; one end of the second guide microgroove is connected to a first guide microgroove vertically downward, and a water storage device is provided at the lower end of the first guide microgroove.

[0015] The principle of the invention is as follows: During daytime periods of strong sunlight and low relative humidity, a rotating device rotates the solar panel upward, allowing the solar cell to generate electricity. At night and early morning, when sunlight is weak and relative humidity is high, the rotating device rotates the hydrophobic glass / silicone oil interlayer upward. The solar cell is connected to a semiconductor refrigeration panel circuit, which cools the upper hydrophobic steel plate / silicone oil interlayer, lowering the temperature and enhancing condensation. The hydrophobic steel plate condenses moisture in the air, forming droplets that aggregate and grow. Sufficiently large condensed droplets are captured by the silicone oil area and transported to the diversion microgrooves and water storage device.

[0016] The beneficial effects of the present invention are as follows: the refrigeration and cooling surface of the device allows the moisture in the air to reach the dew point faster and in greater amounts and accumulate on the surface of the hydrophobic copper plate / silicone oil lubricating layer; the interphase structure of the surface of the hydrophobic copper plate / silicone oil lubricating layer gives it anisotropic wettability differences, and water droplets condensed on the hydrophobic steel plate are transferred to the hydrophilic lubricating layer, and the hydrophilic lubricating layer has a low rolling angle of water, allowing the water droplets to move easily and be collected in the water storage device.

[0037] Preparation method:

[0038] (1) First, take the solar cell panel and the semiconductor refrigeration panel, and apply silicone as an adhesive between the two panels to bond them together.

[0039] (2) The customized copper plates were immersed in fluorosilane for 5 minutes to obtain hydrophobic modification, and the hydrophobic copper plates were kept for future use.

[0040] (3) A gap-interlaced mold 72 is made by 3D printing, such as Figure 7 As shown, the gap-interlaced mold 72 has gaps 71 for placing hydrophobic copper plates.

[0041] (4) Evenly coat the prepared PDMS (polydimethylsiloxane, precursor to curing agent mass ratio of 10:1) on the semiconductor refrigeration plate, then place multiple copper plates into the gaps of the customized interlaced mold, place the interlaced mold side by side with the solar panel and the semiconductor refrigeration plate (so that the bottom of the copper plate is at the same level as the PDMS layer), push the multiple copper plates out of the mold gap together and make them fit with the PDMS to form a copper plate interlaced structure, and remove the mold after curing for 48 hours. Figure 2 、 Figure 7 )

[0042] NOTE: The PDMS layer enables the hydrophobic steel plate to adhere and silicone oil to be adsorbed on it.

[0043] (5) Dimethyl silicone oil is dropped between the interphase hydrophobic copper plates to form an interphase lubricating structure.

[0044] At this point, the water collection interlayer device is completed. ( Figure 2 )

[0045] (6) On both sides (opposite directions), silicone is used to bond the water collection interlayer device and the resin rotating device (made by 3D printing), and the rotating device is connected to the driving rotating device. The driving rotating device rotates the solar cell panel to the upward side during the day, and the solar cell converts light energy into electrical energy; at night or in the morning, the hydrophobic glass / silicone oil interlayer rotates to the top, and the solar cell supplies power to the cooling plate to cool it. After the hydrophobic glass / silicone oil interlayer cools, it condenses the moisture in the air to achieve the purpose of water collection. ( Figure 1 )

[0046] (6) On the other two sides (opposite directions), use wires to connect the solar cell panels and the semiconductor refrigeration panels. The switch side wires are glued to the plastic switch lever to control the opening and closing of the circuit. Figure 3 、 Figure 4 、 Figure 5 )

[0047] (7) Place a resin water storage device (made by 3D printing) below the water collection layer device to collect condensed water. Figure 1 )
