Description

Technical Field

[0001] The utility model relates to the technical field of concrete wall panels, in particular to an active heat-insulating tube-embedded prefabricated wall panel. Background Art

[0002] As people's requirements for comfortable living and working environments continue to increase, building energy conservation has become a major issue in today's construction industry. Wall insulation, as a key link in building energy conservation, is of great significance in reducing energy consumption and improving indoor environmental quality.

[0003] Traditional wall insulation technologies typically involve adding insulation materials, such as polystyrene foam (EPS), extruded polystyrene foam (XPS), polyurethane foam, and rock wool, to the exterior or interior of the wall. These materials can, to a certain extent, reduce the wall's heat transfer coefficient and improve insulation performance. However, they have inherent limitations. Firstly, the insulation performance of traditional insulation materials is often static and cannot be adjusted in real time to changes in indoor and outdoor temperatures or user needs. In the event of large fluctuations in outside temperature, the wall's insulation may not always maintain optimal performance, resulting in unstable indoor temperatures, affecting comfort and increasing energy consumption. Secondly, traditional wall insulation materials can develop hollowing, shedding, aging, moisture absorption, and deformation over long-term use, affecting the durability and stability of their insulation performance. Furthermore, once the insulation material is damaged or fails, repair and replacement are often difficult and costly. Utility Model Content

[0004] In response to the above-mentioned technical deficiencies, the present invention provides an active thermal insulation embedded pipe prefabricated wall panel, which embeds pipes inside the wall panel and utilizes the circulating flow of fluid to actively adjust the thermal insulation performance of the wall panel, thereby improving the flexibility, adaptability and reliability of the wall panel insulation.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an active insulation embedded tube prefabricated wall panel, comprising a wall body and an embedded tube, the wall body being provided with a window opening, the wall body comprising an exterior finish, an insulation layer, a structural layer and an interior finish, the embedded tube being arranged in a serpentine manner within the structural layer of the wall body, the embedded tube comprising a water inlet and a water outlet, temperature sensors being placed at both the water inlet and the water outlet, and the temperature sensors being electrically connected to a data collector.

[0006] Furthermore, the water inlet and the water outlet are in the same direction, and the water inlet is below the water outlet.

[0007] Furthermore, the placement interval of the embedded pipes is greater than 100 mm and less than 300 mm.

[0008] Furthermore, the prefabricated wall panels also include an external cold and heat source, which is waste heat, solar energy, a cooling tower or an underground pipe. The external cold and heat source is connected through a circulating water pump and an embedded pipe. The water inlet of the embedded pipe is connected to the water inlet of the water distributor of the external cold and heat source. The water distributor is arranged at the top of the external cold and heat source, and the water outlet of the embedded pipe is connected to the water outlet of the water collecting pan of the external cold and heat source. The water collecting pan is arranged at the bottom of the external cold and heat source.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] 1. This utility model can make full use of low-grade cold and heat sources to maximize energy utilization. Low-grade cold and heat sources are mostly renewable or waste heat resources, reducing dependence on high-grade energy, reducing energy consumption and environmental impact;

[0011] 2. The rational distribution of embedded pipes within the wall panels of this utility model ensures more uniform heat and cold transfer, effectively avoiding localized heating that can cause significant temperature gradients in the room. The slow heat transfer characteristics of the circulating water make temperature changes more gradual, reducing the impact of temperature fluctuations on human comfort and creating a more stable and pleasant indoor climate.

[0012] 3. The water in the embedded pipes inside the wall panels of this utility model forms circulating water, which increases the thermal inertia of the wall panels and improves their thermal insulation capabilities. In winter, it can reduce indoor heat loss to the outside; in summer, it can prevent outdoor heat from entering the room, further improving the building's energy efficiency and reducing cooling and heating loads.

[0013] 4. The embedded pipes in the present invention are prefabricated inside the wall panels, thus forming a relatively independent and closed circulation system, thereby reducing the entry of dust and impurities and reducing the probability of system failure. BRIEF DESCRIPTION OF THE DRAWINGS

The embedded tubes 2 are arranged in a serpentine pattern within the structural layer 103 of the wall body 1, ensuring that the embedded tubes 2 are evenly distributed throughout the wall panel, greatly increasing the contact area between the wall panel and the embedded tubes. The embedded tubes 2 include a water inlet 5 and a water outlet 6. Temperature sensors 4 are placed at each of the water inlet 5 and the water outlet 6. The temperature sensors 4 are electrically connected to a data acquisition device to monitor and provide real-time feedback on the water temperature in the embedded tubes 2.

The water inlet 5 of the embedded pipe 2 is connected to the water inlet of the water distributor 9 of the external cold and heat source 7. The water distributor 9 is arranged at the top of the external cold and heat source 7 and can evenly spray hot water on the filler of the external cold and heat source. The water outlet 6 of the embedded pipe 2 is connected to the water outlet of the water collecting pan 10 of the external cold and heat source. The water collecting pan 10 is arranged at the bottom of the external cold and heat source 7 for collecting cooled water.
