Description

Technical Field

[0001] The present application relates to the technical field of glass roofs, and in particular to a self-evaporation cooling glass roof. Background Art

[0002] Modern agricultural plant factories, such as vegetable planting bases, mostly use greenhouses or indoor planting, and their roofs are paved with glass to ensure the sunlight required for plant photosynthesis. Although glass is light-transmissive, the temperature in the glass room rises quickly and the temperature is high. If you want the plants to grow healthily, you need to install air conditioners and other equipment to cool them down, which increases energy consumption and thus increases costs.

[0003] To this end, the present application provides a self-evaporative cooling glass roof, which cools the room by self-heating, reduces the use of external equipment such as air conditioners, and thus reduces energy consumption. Utility Model Content

[0004] The purpose of the present application is to solve the problems existing in the prior art and to propose a self-evaporating cooling glass roof.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A self-evaporation cooling glass roof comprises a triangular roof, wherein surface glass and inner glass are vertically embedded in the inclined surfaces on both sides of the roof, and a sealed evaporation chamber is formed between the surface glass and the inner glass. A closed water tank is installed at the bottom of the inclined surfaces on both sides of the roof, and the water tank is connected to the bottom of the evaporation chamber. The bottom of the water tank is connected to the upper end of the evaporation chamber through a water pump, and an exhaust hole is arranged on the top wall of the upper end of the evaporation chamber.

[0007] A circulation cavity is arranged on the roof below the inner layer of glass. The circulation cavity is connected with the evaporation cavity. A fan is connected at the lower end of the circulation cavity and an air outlet is arranged at the upper end.

[0008] Preferably, a drain pipe is provided at the bottom end of the circulation chamber.

[0009] Preferably, a dehumidification pipe is provided on the inner layer of glass above the fan, and a breathable membrane is provided in the dehumidification pipe.

[0010] Preferably, the roof includes a hollow crossbeam, with a circular frame fixedly installed on both sides of the crossbeam, a pad is provided in the middle of the inner wall of the frame, the surface glass box and the inner glass are separated and installed in the frame along the pad to form an evaporation chamber, and water holes communicating with the water tank and the inner cavity of the crossbeam are respectively provided at both ends of the frame.

[0011] Preferably, inclined eaves are provided on both sides of the cross beam above the exhaust holes, and the bottom end of the eaves is a slope.

[0012] Preferably, the bottom wall of the frame is a grid-type support plate.

[0013] Preferably, a plurality of spacers are evenly distributed between the surface glass and the inner glass.

[0014] Compared with the prior art, the present application provides a self-evaporation cooling glass roof, which has the following beneficial effects:

[0015] 1. This solution uses surface glass and inner glass to form an evaporation chamber. By injecting clean water into the evaporation chamber, the clean water flows along the surface of the inner glass in the evaporation chamber to form a water film. Under the action of sunlight and indoor temperature, the water film evaporates and absorbs heat continuously to form a cooling effect. A circulation chamber is set under the inner glass. The fan draws the indoor hot air into the circulation chamber to exchange heat with the evaporation chamber for cooling, and then re-injects the cooled air into the room. In this way, cooling is carried out by evaporating and absorbing heat through water film circulation, which has low energy consumption and reduces the working energy consumption of refrigeration equipment such as air conditioners. Then, gas circulation heat exchange and cooling are used, and the two cooperate to further improve the cooling effect.

[0016] 2. The evaporation chamber is connected to the circulation chamber. Part of the air injected into the circulation chamber by the fan enters the evaporation chamber, and then is discharged into the air from the exhaust hole above with water vapor, thereby dissipating the heat, accelerating the heat dissipation and improving the heat dissipation effect.

[0024] The following will be combined with the attached examples of the present application Figure 1-5 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0025] In order to solve the problems existing in the prior art, the present embodiment provides a self-evaporation cooling glass roof, comprising a triangular roof 1, wherein a surface glass 3 and an inner glass 4 are vertically embedded in the inclined surfaces on both sides of the roof 1, and a sealed evaporation chamber 5 is formed between the surface glass 3 and the inner glass 4. A closed water tank 2 is installed at the bottom end of the inclined surfaces on both sides of the roof 1, and the water tank 2 is connected to the bottom end of the evaporation chamber 5. The bottom end of the water tank 2 is connected to the upper end of the evaporation chamber 5 through a water pump 7, and an exhaust hole 9 is provided on the top wall of the upper end of the evaporation chamber 5;

[0026] A circulation chamber 6 is provided on the roof 1 below the inner glass 4. The circulation chamber 6 is connected to the evaporation chamber 5. A fan 10 is connected to the lower end of the circulation chamber 6, and an air outlet 11 is provided at the upper end.

[0027] Principle details of this embodiment:

[0028] A self-evaporation cooling glass roof comprises a triangular roof 1, which is installed on the top of a building to serve as a roof. The roof 1 is triangular, which is convenient for rainwater to flow down. The inclined surfaces on both sides of the roof 1 are vertically embedded with surface glass 3 and inner glass 4. Both the surface glass 3 and the inner glass 4 have good strength properties, such as tempered glass, to ensure sufficient physical strength. The surface glass 3 and the inner glass 4 are sealed with the roof 1 to form a sealed evaporation chamber 5. The bottom ends of the inclined surfaces on both sides of the roof 1 are installed with closed water tanks 2, which are sealed to reduce the evaporation and overflow of water under sunlight. The water tank 2 is connected to the bottom end of the evaporation chamber 5, and the bottom end of the water tank 2 is connected to a water pump 7. The water outlet of the water pump 7 is connected to a water pipe 8, and the end of the water pipe 8 is connected to the upper end of the evaporation chamber 5.

[0029] A circulation chamber 6 is provided on the roof 1 below the inner glass 4, and the circulation chamber 6 is connected to the evaporation chamber 5. An air inlet is provided at the lower end of the circulation chamber 6 near the inner wall of the building wall, and the air inlet is connected to a fan 10, which is installed on the side wall of the building wall. An air outlet 11 is provided at the upper end of the circulation chamber 6, and the air outlet 11 is connected to the room.

[0030] When in use, the water pump 7 draws clean water from the water tank 2 and inputs the clean water from the water pipe 8 to the top of the evaporation chamber 5. The clean water flows along the surface of the inner glass 4 in the evaporation chamber 5 to form a water film, which produces a capillary phenomenon. Under the action of sunlight and indoor temperature, the water film evaporates continuously, and the evaporation of water absorbs heat to form a cooling effect. The evaporated water vapor flows along the evaporation chamber 5 and is discharged into the air from the exhaust hole 9 above, thereby discharging heat. The water film flows along the evaporation chamber 5 and flows into the water tank 2 for recycling.

[0031] At the same time, the fan 10 extracts the indoor warm air and injects it into the circulation chamber 6, and the warm air exchanges heat with the evaporation chamber 5 in the circulation chamber 6 through the inner glass 4. The warm air is cooled after being cooled, and then injected into the room from the air outlet, increasing the indoor gas flow and improving the evaporation cooling effect.

[0032] In this solution, the surface glass 3 and the inner glass 4 are set up to form a sealed evaporation chamber 5. By injecting clean water into the evaporation chamber 5, the clean water flows along the surface of the inner glass 4 in the evaporation chamber 5 to form a water film, which produces a capillary phenomenon. Under the action of sunlight and indoor temperature, the water film evaporates and absorbs heat continuously to form a cooling effect. Cooling is carried out in the form of cyclic evaporation and heat absorption of the water film, which consumes low energy and reduces the working energy consumption of refrigeration equipment such as air conditioners. The fan 10 causes the indoor gas to circulate and exchange heat with the water film in the evaporation chamber 5 while flowing, and the cooled gas is then injected into the room. The two cooperate to further improve the cooling effect.

[0033] In this embodiment, a water inlet pipe 8 is provided on the side wall of the water tank 2, and a cover is provided at the mouth of the water inlet pipe 8, which is used to store water in the water tank 2, that is, to ensure that the clean water in the water tank 2 is always sufficient for circulation, and to ensure that the water level in the water tank 2 is always located above the connection between the circulation chamber 6 and the water tank 2 and the connection between the evaporation chamber 5 and the water tank 2, so as to prevent the water vapor in the evaporation chamber 5 from flowing into.

[0034] In a further embodiment of the present invention, a drain pipe 8 is provided at the bottom of the circulation chamber 6, and the outlet of the drain pipe 8 extends to the outside. When indoor gas is injected into the circulation chamber 6 and condensed water appears, the condensed water flows down and merges into the water tank 2, so as to avoid the condensed water in the circulation chamber 6 from gathering and affecting the gas flow.

[0035] In a further embodiment of the present solution, a dehumidification pipe 14 is provided on the inner glass 4 above the fan 10 , and a breathable membrane 15 is provided inside the dehumidification pipe 14 .

[0036] Principle details of this embodiment:

[0037] The bottom of the inner glass 4 is drilled with a through hole above the air inlet, and a dehumidification pipe 14 is embedded in the through hole, so that the circulation chamber 6 is connected with the evaporation chamber 5. The dehumidification pipe 14 is located above the air inlet. A breathable membrane 15 is provided in the air pipe. The breathable membrane 15 is a waterproof breathable membrane 15, which can pass small molecules such as gas and intercept large molecules such as water molecules.

[0038] When in use, the fan 10 injects indoor air into the circulation chamber 6, and most of the gas floats up along the circulation chamber 6 and enters the room from the upper air outlet. Part of the gas is injected into the evaporation chamber 5 from the dehumidification pipe 14, and floats up along the dehumidification pipe 14, and then discharged from the exhaust hole 9 at the upper end of the evaporation chamber 5, quickly taking the water vapor away from the evaporation chamber 5, accelerating the heat dissipation, that is, accelerating the temperature reduction. The dehumidification pipe 14 is provided with a breathable membrane 15 to prevent the water in the evaporation chamber 5 from spilling into the circulation chamber 6.

[0039] In a further embodiment of the present solution, in the present embodiment, a specific structure of a frame 102 is provided which can realize the fixed installation of the surface glass 3 and the inner glass 4 and the circulation of clean water:

[0040] The roof 1 comprises a hollow crossbeam 101, with a circular frame 102 fixedly mounted on both sides of the crossbeam 101, a pad 103 provided in the middle of the inner wall of the frame 102, the surface glass 3 and the inner glass 4 are separated and installed in the frame 102 along the pad 103 to form an evaporation chamber 5, and water holes 104 communicating with the water tank 2 and the inner cavity of the crossbeam 101 are provided at both ends of the frame 102, so that clean water can circulate.

[0041] In a further embodiment of the present invention, both sides of the cross beam 101 are provided with inclined outer eaves 16 above the exhaust holes 9, and the bottom of the outer eaves 16 is a slope to prevent rainwater from flowing back into the evaporation chamber 5 on rainy days. The bottom of the outer eaves 16 is a slope, which can better guide the water vapor to dissipate relative to the plane and prevent some gas from flowing back in the dead corner of the plane.

[0042] In a further embodiment of the present invention, the bottom wall of the frame 102 has a grid-like support plate 12. The support plate 12 supports the bottom surface of the inner glass 4 to provide auxiliary support, thereby preventing the middle of the inner glass 4 from hanging in the air and falling after a long time, so that the installation of the surface glass 3 and the inner glass 4 is more stable.

[0043] In a further embodiment of the present invention, a plurality of pads 13 are evenly distributed between the surface glass 3 and the inner glass 4. The pads 13 provide uniform force and stable support between the surface glass 3 and the inner glass 4. The pads 13 are cylindrical and do not affect the flow of clean water.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
