Description

Technical Field

[0001] This invention belongs to the field of building energy conservation and building envelope materials technology, and particularly relates to a composite color steel sandwich panel with a replaceable phase change temperature regulation module and intelligent thermal management function and its preparation method. Background Technology

[0002] With the increasing demands for industrialized construction and energy conservation and emission reduction, lightweight, efficient, and easy-to-construct building envelope materials are widely used in temporary and prefabricated buildings. Color steel sandwich panels, due to their excellent mechanical properties and ease of installation, have become a commonly used building envelope material in prefabricated housing construction. However, the thermal insulation performance of traditional color steel sandwich panels depends on the core material itself (such as polystyrene, polyurethane, or rock wool). Their high thermal inertia and slow response mean they cannot adjust to changes in ambient temperature, resulting in poor indoor comfort under high-temperature or low-temperature conditions, and high load and energy consumption on air conditioning systems.

[0003] In recent years, phase change materials (PCMs) have become a hot topic in building energy conservation research due to their heat absorption, heat storage, and temperature regulation functions. However, existing technologies mostly employ microencapsulated PCM embedding methods, which not only involve complex production processes but also pose risks of leakage and high costs. Therefore, there is an urgent need for a phase change building component solution with a simpler structure, more controllable costs, and suitability for industrial production.

[0004] While existing phase change material (PCM) composite color steel sandwich panels can improve thermal insulation performance, they suffer from two major problems: first, the PCM layer is usually embedded inside the core material or attached and fixed, making it impossible to replace once the material ages or leaks; second, the PCM performance is difficult to adjust with the seasons or usage environment, leading to energy efficiency degradation. Traditional color steel panels mostly use a single insulation core structure, making dynamic thermal management difficult. Furthermore, current manufacturing processes generally employ a one-time composite process, resulting in difficult panel maintenance and limited lifespan. Summary of the Invention

[0005] The present invention aims to provide a replaceable phase change temperature-regulating modular composite color steel sandwich panel and its preparation method, so as to solve the problems of existing phase change insulation blankets being non-replaceable and difficult to maintain.

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

[0007] A replaceable phase change temperature-regulating modular composite color steel sandwich panel includes: phase change insulation blankets of different specifications, a substrate, and a thermally conductive conditioning layer. The phase change insulation blankets of different specifications are distinguished according to their different phase change temperature ranges. The substrate includes an upper surface color steel plate, a core material, and a lower surface color steel plate. The upper and lower surface color steel plates are respectively disposed on the upper and lower surfaces of the core material. A thermally conductive conditioning layer is uniformly distributed on the outer surface of the upper surface color steel plate. The phase change insulation blanket is installed on the outer surface of the thermally conductive conditioning layer by magnetic positioning and sliding groove insertion. Several heat-conducting sheets are provided on the side of the phase change insulation blanket facing the thermally conductive conditioning layer, and an RFID tag is provided on the side of the phase change insulation blanket away from the thermally conductive conditioning layer. The RFID tag records the phase change module type and performance parameters of the corresponding phase change insulation blanket. Seasonal thermal management can be achieved by replacing the phase change insulation blanket with one suitable for the ambient temperature according to changes in ambient temperature.

[0008] Preferably, in the aforementioned replaceable phase change temperature regulating modular composite color steel sandwich panel, the RFID tag reads the phase change module type and performance parameters of the current phase change insulation blanket through the RFID identification system. The RFID identification system is connected to an external monitoring system. The external monitoring system determines the phase change insulation blanket suitable for the current ambient temperature based on the ambient temperature. If the phase change insulation blanket suitable for the current ambient temperature determined by the external monitoring system is different from the phase change module of the phase change insulation blanket identified by the RFID identification system, the external monitoring system prompts the staff to replace it until the phase change insulation blanket suitable for the current ambient temperature determined by the external monitoring system is the same as the phase change module of the phase change insulation blanket identified by the RFID identification system.

[0009] Preferably, in the above-mentioned replaceable phase change temperature-regulating modular composite color steel sandwich panel, a temperature sensor is provided between the phase change insulation blanket and the thermal conductivity regulating layer, and the temperature sensor is communicatively connected to an external monitoring system.

[0010] Preferably, in the above-mentioned replaceable phase change temperature-regulating modular composite color steel sandwich panel, the upper surface color steel plate is a color-coated steel plate with a thickness of 0.4 to 0.7 mm, which is used to provide panel strength and corrosion protection.

[0011] Preferably, in the above-mentioned replaceable phase change temperature-regulating modular composite color steel sandwich panel, the core material layer is any one of polystyrene, polyurethane, rock wool or glass wool; the thickness of the core material ranges from 50mm to 100mm.

[0012] Preferably, in the above-mentioned replaceable phase change temperature-regulating modular composite color steel sandwich panel, the lower surface color steel plate is a color-coated steel plate with a thickness of 0.4 to 0.7 mm, which is used to provide panel strength and corrosion protection.

[0013] Preferably, in the above-mentioned replaceable phase change temperature regulating modular composite color steel sandwich panel, the phase change insulation blanket uses either paraffin or fatty acid as the phase change carrier, which is impregnated in the fiber blanket matrix to form a flexible insulation layer.

[0014] Preferably, in the aforementioned replaceable phase change temperature-regulating modular composite color steel sandwich panel, the phase change temperature range of the different specifications of the phase change insulation blanket is 15–32℃, covering the human comfort range; the areal density is 2–4 kg / m³. 2 Adjustments are made based on the demand for thermal energy storage.

[0015] Preferably, in the aforementioned replaceable phase-change temperature-regulating modular composite color steel sandwich panel, a sliding groove and magnetic positioning component are embedded on the outer surface of the heat-conducting adjustment layer to form a standardized quick-release interface, allowing for single-panel replacement with only tools. This interface has weather-resistant sealing performance and can be repeatedly installed and removed ≥100 times.

[0016] This invention also discloses a method for preparing a replaceable phase change temperature-regulating modular composite color steel sandwich panel, comprising the following steps:

[0017] Step 1, Preparing the substrate: The substrate includes an upper surface color steel plate, a core material, and a lower surface color steel plate, wherein the upper surface color steel plate and the lower surface color steel plate are respectively disposed on the upper and lower surfaces of the core material;

[0018] Step 2, thermal conductivity adjustment layer assembly: The thermal conductivity adjustment layer is evenly distributed on the outer surface of the upper color steel plate, and a composite interface is formed by hot pressing or spraying curing.

[0019] Step 3, Prefabrication of connection interface: A sliding groove and magnetic positioning component are embedded on the outer surface of the heat conduction adjustment layer to form a standardized quick-release interface;

[0020] Step 4, Phase Change Module Prefabrication: The phase change insulation blanket is poured and packaged according to specifications, and heat-conducting sheets and RFID tags are embedded. Several heat-conducting sheets are provided on the side of the phase change insulation blanket facing the heat-conducting adjustment layer, and the RFID tag is provided on the side of the phase change insulation blanket away from the heat-conducting adjustment layer. Step 5, Module Installation and Testing: The phase change module is pushed into position along the slide groove and automatically locked. The system identifies the phase change module parameters through the RFID tag and completes the initial calibration.

[0021] Step 6, Intelligent Control Linkage: The RFID tag reads the phase change module type and performance parameters of the current phase change insulation blanket through the RFID identification system. The RFID identification system communicates with the external monitoring system. The external monitoring system determines the phase change insulation blanket suitable for the current ambient temperature based on the ambient temperature. If the phase change module of the phase change insulation blanket determined by the external monitoring system is different from that of the phase change insulation blanket identified by the RFID identification system, the external monitoring system prompts the staff to replace it until the phase change module of the phase change insulation blanket determined by the external monitoring system is the same as that of the phase change insulation blanket identified by the RFID identification system, thus realizing seasonal thermal management.

[0022] As can be seen from the above-disclosed technical solutions, the beneficial effects of the present invention compared with the prior art are as follows:

[0023] In summary, this invention provides a replaceable phase change temperature-regulating modular composite color steel sandwich panel and its preparation method. It employs phase change insulation blankets of different specifications, a substrate, and a thermally conductive regulating layer. The phase change insulation blankets of different specifications are distinguished according to their different phase change temperature ranges. The substrate includes an upper surface color steel plate, a core material, and a lower surface color steel plate. A thermally conductive regulating layer is uniformly distributed on the outer surface of the upper surface color steel plate. The phase change insulation blanket is installed on the outer surface of the thermally conductive regulating layer via magnetic positioning and a sliding groove insertion method. Several heat-conducting sheets are provided on the side of the phase change insulation blanket facing the thermally conductive regulating layer, and an RFID tag is provided on the side of the phase change insulation blanket away from the thermally conductive regulating layer. The RFID tag records the phase change module type and performance parameters of the corresponding phase change insulation blanket. By replacing the phase change insulation blanket with one suitable for the ambient temperature according to changes in ambient temperature, seasonal thermal management is achieved. On the one hand, this invention achieves modular management of the phase change insulation unit by separating the phase change insulation blanket from the substrate. Different specifications of the phase change insulation blankets are differentiated according to their phase change temperature ranges, and the blankets are installed on the outer surface of the heat-conducting adjustment layer via magnetic positioning and sliding groove insertion. This allows for rapid installation and replacement of the phase change insulation blankets, effectively solving the problem of difficult maintenance and replacement of existing phase change insulation blankets. On the other hand, by adding RFID tags to the phase change insulation blankets, this invention not only enables monitoring and management of the entire lifecycle of the blankets but also allows for linkage with external monitoring systems, automatically prompting for replacement of high or low temperature range modules based on ambient temperature, achieving intelligent seasonal thermal management. Furthermore, this invention achieves efficient heat transfer by introducing a heat-conducting adjustment layer and heat-conducting sheets between the phase change insulation blanket and the substrate. In addition, this material is easy to maintain, recyclable, low-carbon, and energy-saving, making it particularly suitable for temporary buildings, prefabricated housing, and detachable construction site facilities.
