Description

Technical Field

[0001] This utility model relates to the field of heat-insulating roof technology, specifically to a heat-insulating roof structure. Background Technology

[0002] Insulated roof structures are a special design used in buildings or industrial equipment. They aim to reduce heat transfer in the roof area by employing insulation materials and optimizing structural layout, thereby lowering indoor temperatures, improving energy efficiency, and enhancing the thermal environment. These structures typically include insulation layers, supporting frames, and sealing treatments. They effectively block heat conduction, convection, and radiation, and are widely used in building roofs, industrial furnaces, refrigeration equipment, and other fields to meet diverse insulation and heat preservation requirements.

[0003] In existing insulated roof panel technologies, a common design involves installing water pipes inside the roof panel and filling it with water, utilizing the high specific heat capacity of water to absorb heat and achieve an insulation effect. However, this design inevitably increases the weight of the roof panel, which is particularly noticeable when the area covered by the roof panel is large. This weight increase poses a significant challenge to the load-bearing capacity of the building structure. To ensure structural safety, architects may need to improve the load-bearing capacity of the building structure, which not only increases construction costs but may also adversely affect the overall performance and safety of the building. Therefore, an insulated roof panel structure is proposed to address the above issues. Utility Model Content

[0028] Please see Figure 1-7 This utility model provides a technical solution:

[0029] A heat-insulating roof structure includes an aluminum foil heat-insulating roll layer 1, a polyurethane heat-insulating layer 2, and a thermal break layer 3. A heat dissipation layer 4 is fixedly connected to the inner side of the thermal break layer 3, and an atomizing component 5 is fixedly connected to the lower end of the heat dissipation layer 4. The heat dissipation layer 4 includes a heat-insulating support plate 41, with pressure-relieving holes 42 opened on the inner side of the heat-insulating support plate 41. An aluminum alloy coil 43 is fixedly connected to the inner side of the heat-insulating support plate 41, and a first external pipe 44 and a second external pipe 45 are fixedly connected to the front end of the aluminum alloy coil 43. An expansion cylinder 47 is fixedly connected to the lower end of the first external pipe 44. A fan 46 is fixedly connected to the bottom end. The atomizing component 5 includes a water tank 51. A suspension cylinder 52 is fixedly connected to the top of the water tank 51. An impact block 53 and a separator ring 54 are fixedly connected to the inner side of the suspension cylinder 52. A conical cylinder 55 is fixedly connected to one side of the separator ring 54. An outer shell 56 is fixedly connected to the outer side of the conical cylinder 55. A water channel 57 is opened on the inner side of the outer shell 56. A water inlet pipe 58 is fixedly connected to the bottom end of the outer shell 56. A conical groove 59 is opened on the inner side of the conical cylinder 55. The bottom end of the second outer pipe 45 is fixedly connected to the top end of the suspension cylinder 52.

[0030] As a further implementation of this solution, a polyurethane insulation layer 2 is fixedly connected to the bottom end of the aluminum foil insulation roll layer 1. The bottom end of the polyurethane insulation layer 2 is fixedly connected to the top end of the insulation support plate 41. The bottom end of the insulation support plate 41 is fixedly connected to the top end of the mounting plate 6. A gap is provided between the bottom end of the polyurethane insulation layer 2 and the top end of the mounting plate 6. Through the above arrangement, this layered structure design makes the polyurethane insulation layer 2 of the insulation top plate form a stable connection with the insulation support plate 41 and the mounting plate 6, while maintaining a certain gap to facilitate air flow and further improve the insulation effect.

[0031] As a further implementation of this solution, the heat dissipation layer 4 is embedded inside the thermal break layer 3, with the top of the heat dissipation layer 4 flush with the top of the thermal break layer 3. The top of the thermal break layer 3 is fixedly connected to the bottom of the polyurethane insulation layer 2. Through holes are provided at both the left and right ends of the thermal break layer 3. The pressure relief holes 42 penetrate the inner side of the thermal insulation support plate 41 on both sides. The front end of the thermal break layer 3 is provided with an installation hole. The front end of the aluminum alloy coil 43 is fixedly connected to the inner side of the installation hole of the thermal break layer 3. Through the above settings, not only is the circulation of air and water facilitated, but also the stable connection between the components is ensured, enhancing the stability and heat dissipation performance of the entire thermal insulation top plate structure.

[0032] As a further implementation of this solution, the heat insulation support plate 41 has an installation hole on its inner side, and the aluminum alloy coil 43 is inserted and fixed inside the installation hole of the heat insulation support plate 41. The aluminum alloy coil 43 extends out of the outer side of the thermal break layer 3. The inner side of the aluminum alloy coil 43 is a hollow structure. Through the above arrangement, it can absorb and conduct heat, and at the same time, the internal air flow further promotes the dissipation of heat, thereby enhancing the heat dissipation function of the heat insulation top plate.

[0033] As a further implementation of this solution, the inner side of the first outer pipe 44 is hollow. The aluminum alloy coil 43 is connected to the inner side of the first outer pipe 44. The first outer pipe 44 is connected to the inside of the fan 46 through the expansion tube 47. The aluminum alloy coil 43 is connected to the inner side of the suspension tube 52. A gap is provided between the bottom end of the suspension tube 52 and the water tank 51. The water inlet pipe 58 extends into the inside of the water tank 51. The inner side of the water inlet pipe 58 is hollow. The water flow channel 57 runs vertically through the inner side of the outer solid shell 56. The inner side of the water inlet pipe 58 is connected to the flow channel 57. Water channel 57 is connected, and conical groove 59 penetrates the inner side of conical cylinder 55 from top to bottom. Through the above arrangement, the low-pressure area generated by the Venturi effect can be effectively utilized to guide air flow and accelerate water evaporation, thereby absorbing heat more efficiently and realizing the heat dissipation function of the heat-insulating roof plate. Water is precisely guided to the low-pressure area at the upper end of conical groove 59, and the water is dispersed into fine water droplets or water film by utilizing the Venturi effect, increasing the contact area between water and air, thereby more effectively utilizing evaporation to absorb heat for cooling and improving the heat dissipation efficiency of the heat-insulating roof plate.

[0034] Workflow: When the insulated roof panel dissipates heat, the aluminum foil insulation roll layer 1 has excellent heat insulation, waterproof and moisture-proof functions, and extremely low solar radiation absorption rate, which can reflect more than 93% of solar radiation. The polyurethane insulation layer 2 is much lower than traditional insulation materials. The polyurethane insulation layer 2 has high compressive strength and shear strength, and can withstand greater pressure without deformation. It is suitable for occasions that need to withstand certain loads. The insulation support plate 41 and the thermal break layer 3 are made of high polymer materials such as polyamide PA66 or polyvinyl chloride PVC, which play a role in heat insulation and sound insulation. The heat of the polyurethane insulation layer 2 is reduced and guided to the mounting plate 6 through the thermal break layer 3.

[0035] The heat absorbed by the insulated roof plate is dissipated, which can significantly reduce the heat inside the building. The aluminum alloy coil 43 is made of aluminum alloy and has heat absorption properties. The aluminum alloy coil 43 can absorb the heat inside the thermal break layer 3. The fan 46 is started to draw air into the expansion tube 47. At this time, the outside air will enter the interior of the conical groove 59 through the gap between the water tank 51 and the suspension tube 52. The partition ring 54 acts to seal the gap between the suspension tube 52 and the conical tube 55. When the air is blown out from the upper part of the conical groove 59, the fluid velocity will increase and the pressure will decrease due to the narrower upper end of the conical groove 59. This is the Venturi effect. At this time, the pressure near the water channel 57 near the upper end of the conical groove 59 is lower. Water enters the water channel 57 from the inlet pipe 58 and is then sprayed from the water channel 57 onto the impact block 53. At this time, the water collides with the impact block 53 to form tiny water droplets or water films. These water droplets or water films enter the interior of the second outer pipe 45 and the aluminum alloy coil 43 from the suspension cylinder 52, and then flow out through the aluminum alloy coil 43 and the first outer pipe 44. When the water droplets or water films enter the interior of the aluminum alloy coil 43, the water droplets or water films will evaporate due to the high temperature inside the aluminum alloy coil 43. The evaporated water droplets or water films will absorb heat, thereby cooling the aluminum alloy coil 43 and achieving the effect of continuous heat absorption by the aluminum alloy coil 43. This realizes the heat dissipation function of the heat insulation roof and significantly reduces the temperature inside the building.

[0036] Based on the above principles, this device avoids the traditional method of filling the interior of the insulated roof panel with water to achieve heat dissipation. Instead, it disperses water droplets or water films to enter the interior of the insulated roof panel, where it cools down by absorbing heat through evaporation. This significantly reduces the total weight of the insulated roof panel, thereby reducing the load on the building and improving its safety. At the same time, the device reduces the use of electrical equipment, enhancing its practicality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
