Description

Technical Field

[0001] This utility model relates to the field of roof insulation technology, and in particular to a roof insulation board system. Background Technology

[0002] Traditional elevated roof insulation systems mainly use elevated insulation panels to form an air gap to prevent direct sunlight from radiating onto the roof panels and to provide shading for the roof structure. Natural convection also occurs within the air gap to remove some of the heat from the elevated area.

[0003] However, natural convection is limited by temperature difference and airflow speed, which reduces the heat dissipation efficiency of traditional elevated roof insulation systems. Utility Model Content

[0004] The main purpose of this invention is to propose a roof insulation board system that aims to solve the problem of low heat dissipation efficiency in existing elevated roof insulation systems.

[0005] To achieve the above objectives, the roof insulation system proposed in this utility model includes: The house body has an enclosure structure and a roof panel, and the roof panel is located within a fixed space enclosed by the enclosure structure. An elevated structure is provided on the roof panel, and the elevated structure has a ventilation channel and an air inlet, with the ventilation channel and the air inlet connected together. The greenhouse is located on the side of the elevated structure away from the roof panel, and the greenhouse has a light-transmitting panel that is inclined towards the direction of sunlight. The greenhouse also has a first exhaust port that communicates with the outside air and a second exhaust port that communicates with the ventilation channel.

[0006] In some embodiments, the enclosure structure includes a first maintenance structure and a second maintenance structure disposed opposite to each other; the light-transmitting panel, the first maintenance structure, and the overhead structure enclose the greenhouse.

[0007] In some embodiments, the elevated structure includes a pier structure and an elevated thermal insulation panel disposed on the pier structure. The pier structure, the elevated thermal insulation panel, and the roof panel enclose the ventilation channel, and the elevated thermal insulation panel has an air inlet between it and the enclosure structure.

[0008] In some embodiments, the number of the bridge pier structures is at least two, and the at least two bridge pier structures are arranged at intervals.

[0009] In some embodiments, the top of the light-transmitting plate has a first vent between it and the first maintenance structure, and the side of the overhead heat insulation plate near the first maintenance structure has a second vent between it and the inner wall of the first maintenance structure.

[0010] In some embodiments, the air inlet is located between the side of the overhead heat insulation panel near the second maintenance structure and the inner wall of the second maintenance structure.

[0011] In some embodiments, the overhead insulation panel has a slope such that the side of the overhead insulation panel closer to the greenhouse is higher than the side of the overhead insulation panel farther from the greenhouse.

[0012] In some embodiments, the overhead insulation panel includes multiple panel units, and the gaps between the multiple panel units are filled with sealant.

[0013] In some embodiments, the gap between the pier structure and the overhead thermal insulation panel is filled with a sealant.

[0014] The technical solution of this utility model involves setting up a greenhouse on the roof panel of the house body. The greenhouse has a light-transmitting panel that is tilted towards the direction of sunlight. The greenhouse also has a first exhaust port that communicates with the outside air and a second exhaust port that communicates with the ventilation channel. The roof panel has an elevated structure with a ventilation channel and an air inlet. The ventilation channel communicates with the air inlet. When solar shortwave radiation penetrates the light-transmitting panel and enters the interior of the greenhouse, the energy accumulates in the greenhouse and heats the air inside, enhancing the greenhouse effect.

[0022] Traditional elevated roof insulation systems mainly employ the laying of elevated insulation panels 24 to form an air gap, thereby preventing direct sunlight from radiating onto the roof panels 12 and providing a shading effect on the roof structure. Natural convection also occurs within the air gap to remove some of the heat from the elevated layer.

[0023] However, natural convection is limited by temperature difference and airflow speed, which reduces the heat dissipation efficiency of traditional elevated roof insulation systems.

[0024] This utility model proposes a roof insulation panel system 100. Please refer to [link / reference]. Figure 1 In one embodiment of this utility model, the roof insulation system 100 proposed by this utility model includes: The house body 10 has an enclosure structure 11 and a roof panel 12, with the roof panel 12 located within a fixed space enclosed by the enclosure structure 11. The overhead structure 20 is located on the roof panel 12. The overhead structure 20 has a ventilation channel 21 and an air inlet 22, and the ventilation channel 21 is connected to the air inlet 22. Greenhouse 30 is located on the side of the elevated structure 20 away from the roof panel 12, and greenhouse 30 has a light-transmitting panel 33 that is inclined towards the direction of sunlight. Greenhouse 30 also has a first exhaust port 31 that communicates with the outside air and a second exhaust port 32 that communicates with the ventilation channel 21.

[0025] The technical solution of this utility model involves setting up a greenhouse 30 on the roof panel 12 of the house body 10. The greenhouse 30 has a light-transmitting plate 33 tilted towards the direction of sunlight. The greenhouse 30 also has a first exhaust port 31 connected to the outside air and a second exhaust port 32 connected to the ventilation channel 21. The roof panel 12 is provided with an overhead structure 20, which has a ventilation channel 21 and an air inlet 22. The ventilation channel 21 is connected to the air inlet 22. When solar shortwave radiation penetrates the light-transmitting plate 33 and enters the interior of the greenhouse 30, the energy accumulates in the greenhouse 30 and heats the air inside the greenhouse 30. The greenhouse effect is enhanced, which can generate a large thermal pressure difference to drive the hot air inside the greenhouse 30 to be discharged at high speed through the first exhaust port 31. It also drives more cold air from the outside to be drawn into the ventilation channel 21 through the air inlet 22, thereby improving the heat dissipation efficiency.

[0026] Specifically, when solar shortwave radiation penetrates the light-transmitting plate 33 and enters the interior of the greenhouse 30, energy accumulates within the greenhouse 30 and heats the air inside. The heated air, with its temperature rising and density decreasing, rises under buoyancy and is discharged to the outside through the first exhaust port 31. The continuous discharge of hot air from the greenhouse 30 creates a relatively low-pressure zone within the greenhouse 30. This low-pressure zone creates a pressure difference relative to the outside atmospheric pressure. Driven by this pressure difference, cooler outside air is drawn into the ventilation channel 21 through the air inlet 22. As the flowing air passes through the ventilation channel 21, it carries away the heat accumulated in the overhead structure 20 and the nearby roof panel 12. Subsequently, this air enters the greenhouse 30 through the second exhaust port 32, replenishing the gas lost due to the discharge of hot air and participating in the air circulation within the greenhouse 30.

[0027] The light-transmitting panel 33 can be made of a transparent material with high transmittance to short-wave radiation and low transmittance to long-wave thermal radiation. The light-transmitting panel 33 is fixedly connected to the enclosure structure 11 on all four sides.

[0028] Dark-colored heat-absorbing material can be attached to the inside of the greenhouse 30 to absorb solar radiation energy. When short-wave solar radiation penetrates the sun-facing light-transmitting plate 33 and enters the greenhouse 30, the heat-absorbing material inside the greenhouse 30 absorbs the solar radiation heat and simultaneously radiates long-wave radiation outward. The long-wave radiation cannot penetrate the sun-facing light-transmitting plate 33, causing energy to accumulate inside the greenhouse 30. The air temperature inside the greenhouse 30 rises and enters the outside through the first exhaust port 31. The air pressure inside the greenhouse 30 is lower than the air pressure in the ventilation channel 21.

[0029] Meanwhile, shortwave solar radiation strikes the area above the overhead structure 20, capturing some of the energy and conducting it to the air in the ventilation channel 21 below the slab. There is a temperature difference between the upper and lower parts of the overhead structure 20; the upper air is higher, and because air is a poor conductor of heat, the heat absorbed by the overhead slab 20 cannot be conducted to the roof slab, thus providing some insulation. This creates a higher air pressure relative to the inside of the greenhouse 30. This high-pressure air enters the greenhouse 30 through the second exhaust port 32 to balance the pressure difference within the greenhouse 30. The air in the ventilation channel 21, after entering the greenhouse 30, forms a low-pressure zone relative to the outside air, allowing cold outside air to enter the ventilation channel 21 through the air inlet 22.

[0030] In this cycle, the outside air, ventilation duct 21 and greenhouse 30 form a stable air flow state. The heat inside the overhead structure 20 is quickly conducted to the outside through the flowing air, accelerating the dissipation of heat and achieving the effect of overhead insulation.

[0031] In some embodiments, the enclosure structure 11 includes a first maintenance structure 111 and a second maintenance structure 112 disposed opposite to each other; the light-transmitting panel 33, the first maintenance structure 111 and the overhead structure 20 enclose and form a greenhouse 30.

[0032] The enclosure structure 11 also includes a first retaining wall structure 113 and a second retaining wall structure connected to the two ends of the first maintenance structure 111 and the second maintenance structure 112. The two sides of the light-transmitting panel 33 are connected to the first retaining wall structure 113 and the second retaining wall structure, allowing the light-transmitting panel 33 to be tilted and fixed to the overhead insulation panel 24. In one embodiment, the light-transmitting panel 33 is highly transparent glass, allowing more sunlight to enter the greenhouse, selectively absorbing solar radiation energy and converting it into heat energy, thus raising the local temperature.

[0033] In some embodiments, the elevated structure 20 includes a pier structure 23 and an elevated heat insulation panel 24 disposed on the pier structure 23. The pier structure 23, the elevated heat insulation panel 24 and the roof panel 12 enclose a ventilation channel 21, and the elevated heat insulation panel 24 has an air inlet 22 between it and the enclosure structure.

[0034] The pier structure 23 supports the overhead heat insulation panel 24. When solar shortwave radiation shines on the overhead heat insulation panel 24, some of the energy is captured by the panel and conducted to the air in the ventilation channel 21 below it. The air temperature is lower below the panel and higher above, creating high pressure. The air flows along the slope of the panel and enters the greenhouse 30 through the first exhaust port 31, balancing the pressure difference in the greenhouse 30.

[0035] Optionally, the number of pier structures 23 is at least two, and the at least two pier structures 23 are arranged at intervals.

[0036] In one embodiment, multiple bridge pier structures 23 are constructed in rows, and the multiple bridge pier structures 23 and the overhead heat insulation board 24 form several ventilation channels 21.

[0037] In one embodiment, a first exhaust port 31 is provided between the top of the light-transmitting plate 33 and the first maintenance structure 111, and a second exhaust port 32 is provided between the side of the suspended heat insulation plate 24 near the first maintenance structure 111 and the inner wall of the first maintenance structure 111. Due to the temperature difference, a severe air pressure gradient is formed on the upper and lower surfaces of the suspended heat insulation plate 24. The air above the suspended heat insulation plate 24 expands and rises due to heat, while the cold air below the suspended heat insulation plate 24 contracts and sinks, thereby driving the air to flow rapidly and carrying away the accumulated heat.

[0038] In some embodiments, the side of the overhead insulation panel 24 near the second maintenance structure 112 has an air inlet 22 between it and the inner wall of the second maintenance structure 112. The overhead insulation panel 24 has a slope, so that the side of the overhead insulation panel 24 near the greenhouse 30 is higher than the side of the overhead insulation panel 24 away from the greenhouse 30.

[0039] The overhead insulation panel 24 is inclined relative to the roof panel 12 to give it a slope, which can be 2 to 3 degrees. The side of the overhead insulation panel 24 closer to the greenhouse 30 is higher than the side of the overhead insulation panel 24 farther away from the greenhouse 30.

[0040] The overhead insulation panel 24 includes multiple panel units, and the gaps between the multiple panel units are filled with sealant. The overhead insulation panel 24 and the roof panel 12 form a ventilation channel 21 for air flow. The overhead insulation panel 24 is used to prevent solar radiation from directly acting on the roof panel 12 and can play a shading role for the roof panel 12.

[0041] Furthermore, the gap between the pier structure 23 and the overhead insulation panel 24 is filled with sealant.

[0042] The gap between the pier structure 23 and the overhead heat insulation board 24 is sealed with a sealant to ensure that the air in their respective ventilation channels 21 does not interfere with each other during the convection process.

[0043] The light-transmitting panel 33 of this utility model uses high-transmittance glass to take advantage of the glass's high short-wave transmittance and low long-wave transmittance. A greenhouse 30 is set up to create an air pressure difference within the roof insulation panel system 100. This air pressure difference drives forced air convection in the ventilation channel 21 within the overhead insulation panel 24, thereby removing heat from the insulation panel and achieving a heat insulation effect.

[0044] The greater the solar radiation intensity, the stronger the air convection within the roof insulation system 100, the more heat is carried away, and the better the insulation effect.

[0045] The above are merely exemplary embodiments of this utility model and do not limit the scope of protection of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
