Description

Technical Field

[0001] The utility model belongs to the field of wallboard heat storage and cold storage, in particular to a quick-detachable phase-change heat storage and cold storage inner wallboard system. Background Art

[0002] When winter comes, some plateaus and northern regions have higher requirements for indoor insulation. Multiple heating devices need to be used at the same time. Too many electrical devices can easily lead to insufficient regional power facilities. Long-term use can also cause structural damage. Therefore, the performance of the building wall itself is required to meet the temperature requirements as much as possible. In summer, some coastal and low-latitude areas have higher temperatures and need to be cooled and stored. Air conditioning alone may not only fail to meet the temperature requirements, resulting in low comfort, but also has the risk of regional power shortage and tripping due to high energy consumption. Therefore, it is necessary to adopt a variety of effective energy-saving technologies and management measures.

[0003] At the same time, when renovating the walls of existing buildings in cold and hot areas, it is even more necessary to ensure the indoor wall insulation and heat storage and cold storage and cooling performance to reduce energy consumption such as air conditioning or floor heating.

[0004] In addition, the functional layer of existing indoor walls is generally composited with the structural layer, and needs to be installed and disassembled as a whole according to the wall modules, which makes the construction very inconvenient.

[0005] In order to achieve the above objectives, there is an urgent need for a structural system for indoor wall heat storage and cold storage that is suitable for convenient installation and replacement of functional layers and can achieve cold resistance and summer heat relief.

[0018] The secondary keel is arranged close to the rear side of the main keel, and the rear surface of the secondary keel does not exceed the rear surface of the main keel. The front side of the secondary keel and the main keels on both sides form an installation space for accommodating the functional layer and the decorative layer.

[0019] Both the main keel and the secondary keel are hollow tubes. The cross section of the main keel is rectangular. The cross section length of the main keel is not less than the sum of the thicknesses of the secondary keel, the functional layer and the decorative layer.

[0020] The foam plastic insulation layer is a polyurethane layer, and the heat conductive material layer is an aluminum plate layer.

[0021] The rear side surface of the hard bottom plate is bonded to the front side surface of the foam plastic insulation layer.

[0022] The detachable hanging structure includes a set of hanging seats and a set of hanging parts;

[0023] The hangers are arranged at intervals along the length of the secondary keel, and include a hanger connection plate, a hanger extension plate and a hanger body.

[0025] The clamping plates are clamped on both sides of the web in the groove so that the hanging parts can be plugged into the hanging seats.

[0026] The mounting connector and the hanger connector are both expansion bolts.

[0027] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0028] The utility model aims at the existing wall surface and considers the comprehensive research on the selection of materials, quick installation and composite mode.

[0029] The wall panel structure of the utility model comprises a vertically arranged base steel frame, the base steel frame comprises a vertically arranged main keel and a horizontally arranged secondary keel; a hanging structure on the secondary keel and a hard bottom plate for hanging; a base material insulation layer hung on the base steel frame, the base material insulation layer comprises a hard bottom plate, a polyurethane layer, and a heat-conducting aluminum plate layer; a hot and cold common water pipe fixed on the base material insulation layer; a phase change energy storage layer attached to the base material insulation layer and the hot and cold common water pipe; and a decorative layer attached to the phase change energy storage layer.

When the phase change energy storage layer is working, heat storage, that is, when hot water is passed, it absorbs its heat and changes phase, solid phase → liquid phase, continuously stores and releases heat energy, and realizes radiant heating for the room; cold storage, that is, when cold water is passed for heat exchange, it changes phase, liquid phase → solid phase, and realizes cold storage that can continuously absorb environmental heat and realize radiant cooling for the room. The combination of cold storage and heat storage functions can meet the needs of different temperature conditions in winter and summer at the same time, and the wall panels are used to cool down or heat, which improves the comfort of the indoor environment.

First, the phase-change energy storage layer, the base material insulation layer and the hot and cold shared water pipes are installed in an assembled manner, which is well optimized in terms of construction technology. It changes the traditional on-site installation construction method in the past and creates a system of "adhesive composite integrated processing of the base material insulation layer and the phase-change energy storage layer composed of a hard base plate, a polyurethane layer and a heat-conducting aluminum plate layer". The heat-conducting aluminum plate layer is installed in a groove-fitting manner, and the hot and cold shared water pipes are embedded in the groove of the base material insulation layer to protect the outer phase-change energy storage layer. The phase-change energy storage layer and the decorative finish are attached to the base material insulation layer to realize modular installation and disassembly in an integrated manner, meet the requirements of lightweight installation, shorten the construction process, and reduce the safety hazards in the construction process. Secondly, the base material insulation layer and the base steel frame of the wall panel, that is, the wall foundation, are quickly disassembled and installed. The base steel frame and the hard base plate of the base material insulation layer are connected through a hanging structure composed of a hanger on the secondary keel and a hanger on the hard base plate, so that multiple unit panels can be installed at the same time, which ensures stability while improving installation efficiency and solves the process problems of the composite installation method of wall panels.

It can absorb and release appropriate amounts of thermal energy, and the composite cold and hot shared water pipes and the heat-conducting aluminum plate layer improve the heat conduction efficiency. At the same time, it is equipped with primary and secondary keels to achieve the purpose of quick installation and disassembly. This phase change energy storage layer system unit can be widely promoted for partition wall installation.
