Description

Technical Field

[0001] This utility model relates to the technical field of heating radiant panel devices, specifically a large-space suspended heating radiant panel. Background Technology

[0002] In modern heating systems, suspended radiant heating panels are widely used in various large spaces, such as industrial plants and large shopping malls, due to their advantages of not taking up floor space and high heating efficiency. They transfer heat to the surrounding space through radiation, achieving efficient heating.

[0003] However, traditional suspended radiant heating panels have many drawbacks. On the one hand, due to the different coefficients of thermal expansion of the materials in each layer, interlayer thermal stress will be generated during long-term heating, causing the heat-conducting layer to peel off from the insulation layer. This not only reduces heating efficiency but also shortens the service life of the equipment. On the other hand, traditional radiant panels mostly use resistance wires as heating elements. These resistance wires are prone to aging and breakage during long-term heating operation, leading to heating failure. Frequent replacement of heating elements increases operating costs and maintenance workload. Summary of the Invention

[0004] (a) Technical issues

[0005] This invention provides a large-space suspended radiant heating panel that solves the problems of easy peeling between layers and easy aging and breakage of heating elements in traditional suspended radiant heating panels.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a large-space suspended radiant heating panel, including a heat dissipation panel, a heating component, and a suspension device. The heat dissipation panel has a composite layered structure, including a first metal heat-conducting layer, a flexible buffer layer, a thermal insulation layer, and a second metal heat-conducting layer that are laminated and connected sequentially from bottom to top. The heating component is embedded between the first metal heat-conducting layer and the flexible buffer layer, and is bonded to the first metal heat-conducting layer through a thermally conductive silicone grease layer. A U-shaped sealing shell is fixedly provided on the edge of the heat dissipation panel. The suspension device includes a hanging rod fixedly provided on the upper end of the U-shaped sealing shell, and a mounting base is fixedly provided on the upper end of the hanging rod.

[0008] Furthermore, the heating component is a carbon fiber heating film with a high-temperature resistant insulating layer on its surface.

[0012] (III) Technical Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. Stable and peel-resistant structure: The unique composite layered structure has a flexible buffer layer between the first metal heat-conducting layer and the heat insulation layer. Utilizing the good flexibility of silicone rubber composite material, it effectively buffers the thermal stress caused by the difference in thermal expansion coefficients of each layer, avoids the heat-conducting layer from peeling off from the heat insulation layer, extends the service life of the equipment, and ensures a long-term stable heating effect.

[0015] 2. Stable heating and long lifespan: The heating component uses a carbon fiber heating film with a high-temperature resistant insulating layer on its surface. Compared with traditional resistance wire, the carbon fiber heating film has more stable performance, is not easy to age and break, reduces maintenance costs, and improves the reliability and safety of the equipment.

[0016] 3. High efficiency and energy saving with reduced heat loss: The thermal insulation layer adopts a composite structure of vacuum insulation board and XPS extruded board. The high-efficiency thermal insulation performance of the vacuum insulation board, combined with the XPS extruded board, further prevents heat from being transferred upwards. At the same time, the U-shaped sealed shell reduces heat loss at the edge of the heat dissipation plate, significantly improving energy utilization and achieving a high-efficiency and energy-saving heating effect.

[0017] 4. Enhanced heat dissipation and improved efficiency: The heat dissipation fins are fixed in the slots at the bottom of the heat dissipation plate, increasing the heat dissipation area, accelerating heat dissipation, improving the overall heat dissipation efficiency, making the room heat up faster and the heating effect better.

[0027] Combined with appendix Figure 1 To be continued Figure 5 A large-space suspended radiant heating panel includes a heat dissipation panel 1, a heating component 2, and a suspension device 3. The heat dissipation panel 1 has a composite layered structure, including a first metal heat-conducting layer 11, a flexible buffer layer 12, a thermal insulation layer 4, and a second metal heat-conducting layer 14, which are laminated and connected sequentially from bottom to top. The heating component 2 is embedded between the first metal heat-conducting layer 11 and the flexible buffer layer 12, and is bonded to the first metal heat-conducting layer 11 through a thermally conductive silicone grease layer 21. A U-shaped sealing shell 15 is fixedly provided on the edge of the heat dissipation panel 1. The suspension device 3 includes a hanging rod 16 fixedly provided on the upper end of the U-shaped sealing shell 15, and a mounting base 17 is fixedly provided on the upper end of the hanging rod 16. The mounting base 17 is fixed to the ceiling by bolts.

[0028] The heating component 2 is a carbon fiber heating film with a high-temperature resistant insulating layer on its surface. The flexible buffer layer 12 is a silicone rubber composite material. The thermal insulation layer 4 is a composite structure of a vacuum insulation board 41 and an XPS extruded board 42. The vacuum insulation board 41 is positioned facing the second metal thermal conductive layer 14. The bottom of the heat dissipation plate 1 is provided with a slot 18, and heat dissipation fins 19 are fixedly engaged inside the slot 18.

[0029] The working principle of this large-space suspended radiant heating panel is as follows: The panel generates heat through the heating component 2. This heat is efficiently transferred to the first metal heat-conducting layer 11 via the thermally conductive silicone grease layer 21. Utilizing the excellent thermal conductivity of the metal, the heat is evenly distributed at the bottom of the panel 1. A flexible buffer layer 12 alleviates thermal stress caused by heating, preventing structural damage. An insulation layer 4 prevents heat from rising, ensuring that heat is primarily radiated downwards. The heat dissipation fins 19 increase the heat dissipation area, accelerating heat dissipation and achieving efficient heating.

[0030] The working process of this utility model of a large-space suspended radiant heating panel is as follows:

[0031] 1. Installation and fixing: Fix the mounting base 17 to the ceiling with bolts, connect one end of the hanger 16 to the mounting base 17, and fix the other end to the upper end of the U-shaped sealing shell 15 to complete the suspension installation of the heat sink 1.

[0032] 2. Electrical heating: When electricity is supplied to heating component 2, i.e., the carbon fiber heating film, the carbon fiber heating film begins to work and generate heat. Because its surface is covered with a high-temperature resistant insulating layer, the safety and stability of the heating process are ensured.

[0033] 3. Heat conduction: The generated heat is rapidly transferred to the first metal thermal conductive layer 11 through the adhered thermally conductive silicone grease layer 21. The first metal thermal conductive layer 11, with the excellent thermal conductivity of metal, quickly and evenly distributes the heat throughout the bottom of the heat sink 1.

[0034] 4. Buffering and Insulation: During heat transfer, the flexible buffer layer 12, i.e., the silicone rubber composite material, buffers the thermal stress caused by the different coefficients of thermal expansion of each layer, preventing the first metal heat-conducting layer 11 from delaminating with the thermal insulation layer 4 due to thermal stress. The thermal insulation layer 4 is composed of a vacuum insulation board 41 and an XPS extruded board 42. The vacuum insulation board 41 is positioned facing the second metal heat-conducting layer 14, effectively preventing heat from being transferred upwards and causing heat to radiate downwards.

[0035] 5. Heat dissipation and heating: The heat at the bottom of the heat dissipation plate 1 is transferred to the heat dissipation fins 19 that are snapped into the slot 18, which increases the heat dissipation area and accelerates the heat dissipation to the surrounding space, thereby achieving the heating function of a large space.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
