Description

Technical Field

[0001] This invention relates to the field of roofing ply technology, specifically to a roofing ply structure capable of adaptive heat dissipation. Background Technology

[0002] Traditional roof construction often uses cast-in-place reinforced concrete structures. With the development of prefabricated construction, modular roof slab technology is also constantly improving, which helps to ensure construction efficiency, shorten the construction cycle, and reduce material waste and construction waste. However, its drawback is that the building modules still basically use reinforced concrete structures, and the insulation of the house is only achieved through the insulation layer, which cannot effectively dissipate the radiant heat from the sun.

[0003] In the existing technology, there are more than one type of roof heat dissipation structure, but often no roof layer structure can provide proper insulation in winter and quickly dissipate the large amount of heat absorbed by the roof in summer.

[0004] In view of the above problems, it is very necessary to design a roof lining structure that can adapt to heat dissipation in order to solve the problems and achieve the purpose of heat preservation or heat dissipation by adapting to the external ambient temperature. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a roofing structure capable of adaptive heat dissipation. Through the coordination of a heat-conducting layer, a heat-conducting structure, and a heat-dissipating structure, it can not only retain the roof's heat through the insulation layer in the low-temperature winter, preventing rapid heat loss, but also enable the roof to quickly dissipate a large amount of heat through the heat-dissipating structure in the high-temperature summer, preventing excessive heat accumulation inside the house and achieving the effect of being warm in winter and cool in summer.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] This invention provides a roof cladding structure capable of adaptive heat dissipation, comprising a wall and a load-bearing layer. A waterproof layer is provided on the upper wall of the load-bearing layer, and a heat-conducting layer is laid between the waterproof layer and the load-bearing layer. A heat dissipation structure is provided on the outer wall of the wall, and a heat-conducting structure connected to the heat dissipation structure is provided inside the wall. The heat-conducting structure can adaptively contact or separate from the heat-conducting layer according to the external temperature, and the heat-conducting layer can transfer heat to the heat dissipation structure through the heat-conducting structure.

[0008] As a further embodiment of the present invention, the heat dissipation structure includes a heat-conducting plate disposed in the wall, wherein a plurality of heat dissipation fins are fixed at equal intervals from top to bottom on the side wall of the heat-conducting plate, and the direction of the heat dissipation fins is inclined downward.

[0009] As a further embodiment of the present invention, both the heat-conducting plate and the heat sink are made of aluminum alloy.

[0010] As a further embodiment of the present invention, the heat-conducting structure includes a heat-conducting lifting plate disposed on the upper end of the heat-conducting plate. An air cavity is formed in the vertical direction on the upper end of the heat-conducting plate. The heat-conducting lifting plate can be lifted and lowered in the air cavity, and the heat-conducting lifting plate and the air cavity are always sealed and connected during the displacement of the heat-conducting lifting plate.

[0011] As a further embodiment of the present invention, a connecting cavity is provided on the lower wall of the heat-conducting layer at a position directly above the air cavity, and the heat-conducting lifting plate can be lifted and lowered within the connecting cavity.

[0012] As a further embodiment of the present invention, both the inner wall of the connecting cavity and the inner wall of the air cavity are provided with thermally conductive silicone sheets, and the thermally conductive lifting plate can transfer heat between the thermally conductive silicone sheets and the thermally conductive layer, and the thermally conductive lifting plate can transfer heat between the thermally conductive silicone sheets and the thermally conductive plate.

[0013] As a further embodiment of the present invention, an airbag is provided inside the heat-conducting layer, and the airbag is sealed to the lower end of the air cavity through a connecting pipe.

[0014] As a further embodiment of the present invention, the heat-conducting lifting plate is made of ceramic.

[0015] As a further embodiment of the present invention, the outer wall of the heat-conducting layer is provided with a heat-insulating layer.

[0016] As a further embodiment of the present invention, the thermally conductive layer is made of ceramic.

[0017] The specific advantages of the adaptive heat dissipation roof ply structure of the present invention are as follows:

[0018] This invention utilizes the combined action of a heat-conducting layer, a heat-conducting structure, and a heat-dissipating structure. Through the physical phenomenon of thermal expansion and contraction of the airbag, the heat-conducting lifting plate in the heat-conducting structure is displaced, achieving contact and separation between the heat-conducting layer and the heat-dissipating structure. This not only enables the insulation layer to retain heat in the roof during cold winters, preventing rapid heat loss, but also allows a large amount of heat from the roof to be quickly dissipated through the heat-dissipating structure during hot summers, preventing excessive heat accumulation inside the house and achieving a comfortable temperature year-round.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example:

[0028] like Figures 1 to 4 As shown, the present invention provides a roof ply structure capable of adaptive heat dissipation, including a wall 1 and a load-bearing layer 2. The load-bearing layer 2 can be a floor deck or other ply that can support the roof and has a certain mechanical strength. A waterproof layer 3 is provided on the upper wall of the load-bearing layer 2. A heat-conducting layer 4 is also laid between the waterproof layer 3 and the load-bearing layer 2. A heat dissipation structure is provided on the outer wall of the wall 1. A heat-conducting structure connected to the heat dissipation structure is provided inside the wall 1. The heat-conducting structure can adaptively contact or separate from the heat-conducting layer 4 according to the external temperature. The heat-conducting layer 4 can transfer heat to the heat dissipation structure through the heat-conducting structure.

[0029] In one embodiment of the present invention, the waterproof layer 3 may be provided with a first waterproof layer 5 and a second waterproof layer 6 from top to bottom, wherein the second waterproof layer 6 is a cement-based waterproof material, made of cement and sodium silicate, and has good density and impermeability, and the first waterproof layer 5 is made of SBS waterproof membrane or asphalt.

[0030] In one embodiment of the present invention, such as Figure 1 As shown, the heat dissipation structure includes a heat-conducting plate 7 disposed in the wall 1. The heat-conducting plate 7 has a plurality of heat dissipation fins 8 fixed at equal intervals from top to bottom on its side wall. The heat dissipation fins 8 are inclined downward. This arrangement can prevent water from accumulating on the heat dissipation fins 8, reduce the risk of water seepage in the wall 1, and extend the service life.

[0031] The heat-conducting plate 7 and the heat sink 8 are both made of aluminum. Aluminum alloy is lightweight, has excellent thermal conductivity, and provides good heat dissipation.

[0032] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the heat-conducting structure includes a heat-conducting lifting plate 9 disposed on the upper end of the heat-conducting plate 7. An air cavity 10 is formed in the vertical direction at the upper end of the heat-conducting plate 7. The heat-conducting lifting plate 9 can be lifted and lowered within the air cavity 10, and the heat-conducting lifting plate 9 and the air cavity 10 are always sealed together during the displacement of the heat-conducting lifting plate 9. In this embodiment, the lower end of the heat-conducting lifting plate 9 is wrapped with a rubber layer, and the lower end of the lifting plate is dynamically sealed to the inner wall of the air cavity 10 through the rubber layer.

[0033] In one embodiment of the present invention, the heat-conducting lifting plate 9 and the heat-conducting layer 4 are made of ceramic. Ceramic has a small heat capacity, does not store heat, and dissipates heat directly, unlike the metal heat sink 8 which forms a "heat ladder" and affects heat dissipation.

[0034] In one embodiment of the present invention, a connecting cavity 11 is formed on the lower wall of the heat-conducting layer 4 at a position directly above the air cavity 10, and the heat-conducting lifting plate 9 can be lifted and lowered in the connecting cavity 11.

[0035] Furthermore, in order to enable sufficient heat transfer between the heat-conducting lifting plate 9 and the heat-conducting layer 4 and the heat-conducting plate 7, heat-conducting silicone sheets 12 are provided on the inner wall of the connecting cavity 11 and the inner wall of the air cavity 10. The heat-conducting lifting plate 9 can transfer heat between itself and the heat-conducting layer 4 through the heat-conducting silicone sheets 12 in the connecting cavity 11, and the heat-conducting lifting plate 9 can transfer heat between itself and the heat-conducting plate 7 through the heat-conducting silicone sheets 12 in the air cavity 10.

[0036] In one embodiment of the present invention, in order to enable the heat-conducting lifting plate 9 to perform spontaneous lifting and lowering actions according to the temperature of the external environment, an airbag 13 is provided in the heat-conducting layer 4. The airbag 13 is sealed to the lower end of the air cavity 10 through a connecting pipe 15. Through the physical phenomenon of thermal expansion and contraction of the airbag 13, the heat-conducting lifting plate 9 in the heat-conducting structure is displaced, thereby realizing the contact and separation between the heat-conducting layer 4 and the heat dissipation structure.

[0037] In one embodiment of the present invention, the outer wall of the heat-conducting layer 4 is provided with an insulation layer 14. The insulation layer 14 is made of rigid polyurethane foam. Rigid polyurethane foam is a low-density microporous foam material with a closed-cell structure, which has a good heat insulation effect. In winter when the outside temperature is low, the insulation layer 14 can lock in the heat of the roof and play a heat insulation role.

[0038] Through the cooperation of the heat-conducting layer 4, the heat-conducting structure, and the heat-dissipating structure, and through the physical phenomenon of thermal expansion and contraction of the airbag 13, the heat-conducting lifting plate 9 in the heat-conducting structure is displaced, realizing the contact and separation between the heat-conducting layer 4 and the heat-dissipating structure. This not only enables the insulation layer 14 to retain the heat of the roof in the low-temperature winter, preventing the rapid loss of heat from the roof, but also enables the large amount of heat from the roof to be quickly dissipated through the heat-dissipating structure in the high-temperature summer, preventing a large amount of heat accumulation inside the house, and achieving the effect of being warm in winter and cool in summer.

[0039] Working principle:

[0040] In the hot summer, the ambient temperature is high, and the gas inside the airbag 13 expands due to heat. The gas enters the air chamber 10 through the connecting pipe 15, and the pressure inside the air chamber 10 increases, causing the heat-conducting lifting plate 9 to move upward. The upper end of the heat-conducting lifting plate 9 moves upward and inserts into the connecting cavity 11. At this time, the heat-conducting layer 4 and the heat-conducting plate 7 are connected through the heat-conducting lifting plate 9 and the heat-conducting silicone sheet 12. A large amount of heat accumulated on the heat-conducting plate 7 is dissipated into the outside air through the heat-conducting plate 7 and the heat sink 8, thereby achieving heat dissipation and cooling of the roof.

[0041] In the cold winter, the ambient temperature is low, and the gas inside the airbag 13 contracts due to the cold. The gas in the air chamber 10 enters the airbag 13 through the connecting pipe 15. The pressure inside the air chamber 10 decreases, causing the heat-conducting lifting plate 9 to move downward. The upper end of the heat-conducting lifting plate 9 moves downward and separates from the connecting chamber 11. At this time, the connection between the heat-conducting layer 4 and the heat-conducting plate 7 is broken. The heat on the heat-conducting plate 7 cannot be dissipated quickly and is slowly accumulated under the heat-insulating effect of the insulation layer 14, thus achieving the roof insulation effect.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
