Description

Technical Field

[0001] This utility model relates to the field of indoor heating equipment technology, and in particular to a low-energy-consumption heating and energy storage ground structure. Background Technology

[0002] In cold regions, heating has always been a major concern for residents. Currently, most areas use centralized heating, decentralized heating, and self-heating. In areas without a unified geothermal heating system, residents generally use self-heating methods, such as electric heating for indoor floor structures.

[0003] Currently, there are many technical problems with indoor floor heating systems using electric heating that urgently need to be solved. For example, during the cold season, due to the high demand for indoor heating, the long-term operation of electric heating floors will lead to a significant increase in energy consumption and electricity costs. Moreover, the installation process of electric heating floors is relatively complicated, requiring the laying of pipelines throughout the house, followed by the installation of the base plate, and finally the installation of the floor. This involves a large amount of work, a long installation period, and complex pipeline layout. Most importantly, the structure is not stable enough. If aging or cracking occurs after long-term use, it will increase the safety risks and easily lead to safety accidents such as fires and electric shocks. Summary of the Invention

[0013] The beneficial effects of this utility model are:

[0014] 1.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1-5 As shown in some illustrative embodiments, a low-energy heating and energy storage ground structure is provided. The ground structure is composed of multiple ground radiant modules assembled by assembly components. The ground radiant modules are the basic units of the overall ground structure, and the assembly components are used to connect adjacent ground radiant modules into a whole, ensuring tight fixation between modules and the stability of the overall ground structure.

[0024] During the actual construction, it is necessary to first ensure that the ground is flat, clean, dry, and free of debris; then, according to the design drawings, the ground radiant modules are assembled one by one using the assembly components to form a complete radiant heating layer. After the assembly is completed, the ground radiant modules are arranged in a matrix, with small gaps between each module to accommodate thermal expansion; finally, flooring, tiles, or other decorative materials can be laid on the assembled radiant heating layer according to the user's needs.

[0025] The ground radiation module includes: an open-top chassis 1, an electric heating coil 2, an insulating wire mesh 3, a phase change material box 4, a spacer plate 5, and a cement layer 6.

[0026] The top-opening chassis 1 is a rectangular shell structure with an opening at the top. It is made of high-temperature resistant materials such as stainless steel, modified polycarbonate, or glass fiber reinforced plastic to ensure safety and durability. The electric heating coil 2 is spirally arranged at the bottom of the top-opening chassis 1. This spiral arrangement helps to evenly distribute heat and improve heating efficiency. The electric heating coil 2 uses resistance wire heating, typically made of a high-resistivity, high-temperature resistant metal material, such as nickel-chromium alloy. It is externally wrapped with insulating material, and an additional metal protective sleeve is installed outside the insulation layer.

[0027] The insulating wire mesh 3 is installed inside the open-top chassis 1 and located above the electric heating coil 2. The main function of the insulating wire mesh 3 is to fix the phase change material box 4 and isolate the phase change material box 4 from the electric heating coil 2, preventing the phase change material box 4 from directly contacting the electric heating coil 2, while allowing heat to be transferred to the phase change material box 4 through the insulating wire mesh 3. The phase change material box 4 is located on the upper surface of the insulating wire mesh 3.

[0028] Specifically, the phase change material box 4 includes an energy storage housing 401 and phase change material 402 filled inside the energy storage housing 401. The energy storage housing 401 is made of materials with good thermal conductivity and high temperature resistance, such as aluminum alloy or copper alloy. The size of the energy storage housing 401 can be adjusted according to the actual heat load requirements of the application to ensure sufficient phase change material storage capacity. During the heat absorption process, the phase change material 402 changes from solid to liquid, absorbing and storing a large amount of latent heat; during the heat release process, it changes from liquid to solid, releasing the stored heat. This phase change process can occur within a relatively narrow temperature range, thereby achieving efficient heat storage and release. Several fins 403 are provided on the top of the energy storage housing 401 to increase the contact area with the spacer 5 and promote rapid heat transfer. During the heat release process, the fins 403 can more effectively transfer the heat released by the phase change material 402 to the upper environment, improving the heat release efficiency.

[0029] The partition plate 5 is bolted to the upper open-type chassis 1 and is located above the phase change material box 4. The cement layer 6 is set on the upper surface of the partition plate 5. The partition plate 5 is mainly for supporting the cement layer 6 and sealing the ground radiation module to form a prefabricated closed structure. This gives the ground radiation module sufficient strength and stability to support the upper floor or tiles, and also facilitates transportation. A recessed platform 501 is formed on the lower surface of the partition plate 5. The bottom of the recessed platform 501 also has a channel for accommodating the top fins of the phase change material box 4. The top of the phase change material box 4 is embedded in the recessed platform 501 to ensure the fixed position of the phase change material box 4 in the module and to ensure the overall firmness of the module.

[0030] The following is a brief description of the working principle of the entire ground-based radiation module:

[0031] Heating stage: During off-peak hours when electricity is cheaper, the electric heating coil 2 starts working and transfers heat to the phase change material in the phase change material box 4. The phase change material 402 undergoes a phase change after absorbing heat and stores energy.

[0032] Heating phase: During peak electricity consumption, the electric heating coil 2 is de-energized. At this time, the phase change material 402 in the phase change material box 4 begins to release the stored heat and radiate heat into the indoor space above to achieve heating.

[0033] Thermal insulation effect: Due to the large heat capacity and slow phase change process of phase change material 402, it can maintain heat supply for a long time during power outages, greatly improving the thermal insulation effect and reducing energy consumption costs.

[0034] Several evenly spaced injection grooves 601 are made on the cement layer 6. After the radiant heating layer is assembled, flooring, tiles or other decorative materials need to be laid. The purpose of the injection grooves 601 is to accommodate more fixing materials, such as concrete, adhesives, etc. These materials are used to fix the upper structure, etc., to ensure that they form a strong bond with the radiant heating layer, thereby improving the strength and stability of the entire ground structure.

[0035] A suspension platform 101 is installed at the four bottom corners of the upper open-type chassis 1, and a leveling bolt 102 is installed on the suspension platform 101. The suspension platform 101 is located at the four bottom corners of the upper open-type chassis 1, providing additional support points for the entire ground radiation module. The leveling bolt 102 is installed on the suspension platform 101, and the height of the upper open-type chassis 1 can be finely adjusted by rotating the bolt, so as to achieve precise level adjustment to adapt to uneven ground conditions. It can also ensure that the upper open-type chassis 1 is evenly stressed, avoiding structural stress concentration caused by uneven ground.

[0036] A pressure-bearing platform 103 is provided on the inner side wall of the upper open-type chassis 1. The pressure-bearing platform 103 is used to support the isolation wire mesh 3 and bear the weight of the material above it, thus reducing the deformation of the side wall of the upper open-type chassis 1 and improving the pressure-bearing capacity of the entire structure. A positioning rod 104 is provided on the upper surface of the pressure-bearing platform 103. An elongated hollow groove 301 is provided on the isolation wire mesh 3. A pressing slot 404 is provided at the bottom of the phase change material box 4. The top of the positioning rod 104 passes through the elongated hollow groove 301 and is embedded in the pressing slot 404. That is, the positioning of the rod 104 can ensure the accurate position of the isolation wire mesh 3 and the phase change material box 4 relative to the upper open-type chassis 1 and avoid displacement during construction.

[0037] The side wall of the top-opening chassis 1 has a wiring port 105. The electrical connection wires of the electric heating coil 2 are led out from the wiring port 105. After being led out, they can be connected in series with the electric heating coils 2 in adjacent modules to form a continuous heating network. Therefore, the wiring port 105 provides a safe and convenient lead-out channel for the electrical connection wires of the electric heating coil 2. Moreover, since the side wall of the top-opening chassis 1 is designed with an inclination, a certain space will be formed between the side walls after the modules are connected. This provides sufficient space for the placement of the electrical connection wires, helps to avoid the electrical connection wires being squeezed when the modules are connected, and facilitates the wiring and fixing of the electrical connection wires, making the installation of the entire radiant heating layer neater and more orderly.

[0038] A retaining plate 106 is provided at the opening of the connection port 105. The retaining plate 106 can protect the electrical connection wire from scratches or wear when passing through the connection port 105, further enhancing the protection of the electrical connection wire.

[0039] The outer side wall of the top-opening chassis 1 is provided with a mounting slot 107. The mounting slot 107 is used in conjunction with the assembly components, which include locking parts 7 and plug-in parts 8. During assembly, the choice between locking parts 7 and plug-in parts 8 can be made according to the position of the ground radiation modules. That is, in two adjacent ground radiation modules, one uses locking parts 7 and the other uses plug-in parts 8. The docking between the modules is the docking between locking parts 7 and plug-in parts 8. Mechanical locking ensures that the modules will not move relative to each other, making the installation method more flexible.

[0040] Both the locking component 7 and the connector 8 are V-shaped mounting plates adapted to the mounting slot 107. The V-shaped mounting plate includes a vertical main plate 9 and an angled locking plate 10, and the two are integrally formed. The angled locking plate 10 is consistent with the inclination angle of the side wall of the upper open chassis 1, and the angled locking plate 10 is embedded in the mounting slot 107. After the angled locking plate 10 is embedded in the mounting slot 107, it works in conjunction with the other parts of the locking component 7 or the connector 8 to achieve locking and fixing between modules.

[0041] In this embodiment, the V-shaped hanging plate in the locking member 7 is designated as the first V-shaped hanging plate 701, and the V-shaped hanging plate in the plug-in member 8 is designated as the second V-shaped hanging plate 801.

[0042] The locking component 7 includes: a first V-shaped hanging plate 701 and an L-shaped locking plate 702.

[0043] Two L-shaped locking plates 702 are symmetrically arranged on the first V-shaped mounting plate 701. Specifically, the L-shaped locking plates 702 are set on the vertical main plate 9. One end of the L-shaped locking plate 702 is connected to the vertical main plate 9, and the other end serves as the locking head end 703 of the L-shaped locking plate.

[0044] The connector 8 includes: a second V-shaped mounting plate 801 and a locking tongue plate 802.

[0045] A locking tongue plate 802 is provided on the V-shaped mounting plate 801. Specifically, the locking tongue plate 802 is provided on the vertical main plate 9, and locking grooves 803 are provided on both sides of the locking tongue plate 802 to accommodate the locking head end 703 of the L-shaped locking plate.

[0046] During assembly, two adjacent ground radiant modules are placed side by side. Each module is equipped with a locking piece 7 or a connector 8. A V-shaped mounting plate is inserted into the mounting slot 107. After connecting the electrical wires between the modules, one of the ground radiant modules is gradually moved until the locking tongue plate 802 of the connector 8 approaches the L-shaped locking plate 702 of the locking piece 7, until the locking tongue plate 802 is embedded between the two L-shaped locking plates 702. When the locking tongue plate 802 is embedded between the L-shaped locking plates 702, the L-shaped locking plates 702 undergo a certain deformation, allowing the lock head end 703 to enter the lock groove 803, thereby fixing the two modules. The cooperation between the locking piece 7 and the connector 8 ensures a firm connection between the modules while allowing for a certain degree of deformation. This helps compensate for minor deviations that may occur during installation, improving the accuracy and convenience of assembly. This assembly method not only simplifies the installation process but also enhances the stability and durability of the overall structure.

[0047] The locking head end 703 of the L-shaped locking plate has a semi-circular cross-section, and the locking groove 803 is an arc-shaped recess. The semi-circular locking head end 703 can smoothly slide into the arc-shaped groove 803, reducing friction and resistance during assembly and making it easier to connect modules. Moreover, because the shapes of the locking head end 703 and the locking groove 803 match, this design helps to achieve precise positioning and ensures that the modules can be correctly aligned during assembly.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
