Description

Technical Field

[0001] This utility model relates to the field of indoor heating technology, specifically a modular wall heating system. Background Technology

[0002] Traditional wall heating systems use hot water or steam as the main heat medium. They are heating devices that transfer heat into the room by pre-embedding pipes inside the wall or hanging radiators on the outside. They usually need to be connected to a central heating network or an independent boiler as the heat source. This system is technically mature, has strong heating stability, and can meet basic heating needs.

[0003] Traditional wall-mounted heating systems have several shortcomings. For example, systems using water pipes are complex to install, requiring pipe laying and wall grooving, resulting in long construction periods and difficult maintenance. Systems using electric heating films suffer from uneven heating, low power density, and difficulty meeting the demands of large-area, high-efficiency heating. Furthermore, existing wall-mounted heating systems generally lack modular design, hindering rapid assembly and flexible expansion, and failing to adapt to diverse decoration needs and spatial layout changes. In addition, some heating elements are prone to displacement and deformation at high temperatures, affecting heating stability and safety. Therefore, improvements are needed in installation efficiency, ease of use, and heating effect. Utility Model Content

[0006] A modular wall heating system is disclosed, comprising several modular heating units of customized sizes arranged in a predetermined shape. Each modular heating unit includes an electric heating core, an aluminum frame, an aluminum plate, and an insulation board. The aluminum plate is fixed to the end face of the aluminum frame away from the wall, and the insulation board is fixed to the end face of the aluminum frame close to the wall. The electric heating core, as the heating element, is disposed within the aluminum frame and located between the aluminum plate and the insulation board. The two electric heating cores in two adjacent modular heating units are electrically connected.

[0007] Furthermore, the electric heating core includes a heat tracing cable body and a fiberglass mesh, both of which are housed within an aluminum frame and located between the aluminum plate and the insulation board; the heat tracing cable body is fixed to the front side of the fiberglass mesh, and the heat tracing cable body extends in a serpentine shape.

[0008] Furthermore, the heat tracing cable itself is sewn and fixed to the fiberglass mesh with a preset stitch spacing and sewing trajectory.

[0009] Furthermore, the aluminum frame has long slots on its sides to allow the ends of the heat tracing cable to extend to the outside.

[0010] Furthermore, the heat tracing cable body has a male fork plug at one end and a female fork plug at the other end; by matching and inserting the male fork plug on one side of the heat tracing cable body into the female fork plug at the end of the adjacent heat tracing cable body, the electrical connection between the two adjacent electric heating cores is realized.

[0011] Furthermore, the modular heating unit also includes a fixing component for securing the modular heating unit to the wall.

[0012] Furthermore, the fixing component includes a positioning block, an expansion bolt, and an expansion sleeve; the positioning block has an end hole on its front end face, and a through insertion hole is provided on the inner wall of the end hole; the expansion bolt is fitted into the insertion hole, and the screwing end can be retracted into the end hole; the expansion sleeve is threadedly engaged with the expansion bolt.

[0013] Furthermore, the fiberglass mesh has through clearance holes, and the insulation board has through fitting openings; a rectangular frame-shaped insert shell is fixed on the inner surface of the aluminum plate for the positioning insert to be matched and inserted; the insert shell passes through the clearance holes and fitting openings in sequence, and remains flush with the outer surface of the insulation board; when the modular heating unit is fixed to the wall, the positioning insert and the rear end face of the insert shell remain flush and are both in contact with the wall.

[0014] Furthermore, the end hole is an internally threaded hole; the aluminum plate has a stepped hole; a fastening bolt B that matches the end hole is installed in the stepped hole; when the fastening bolt B is screwed into the end hole for fastening, the screwing part of the fastening bolt B can be retracted into the stepped hole; a cap can also be detachably installed at the end of the stepped hole, and the cap is flush with the front surface of the aluminum plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] Using a constant power heating cable as the heat source, it can reach a high temperature of 200℃ and a high power density of 600 watts per square meter.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0023] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Example 1

[0024] Please see Figures 1-7 This utility model provides a modular wall heating system, which consists of several customized modular heating units 1 arranged in a predetermined shape. Each modular heating unit 1 includes an electric heating core 2, an aluminum frame 3, an aluminum plate 4, and an insulation board 5. Figure 6 As shown, aluminum plate 4 is set on the end face of aluminum frame 3 away from the wall, and the four top corners of aluminum plate 4 are fastened to aluminum frame 3 by fastening bolts A401. Insulation board 5 is set on the end face of aluminum frame 3 close to the wall. Fitting grooves 301 are evenly distributed on the side of aluminum frame 3, and several mounting feet 501 are evenly distributed on the side of insulation board 5. The mounting feet 501 are fitted into the fitting grooves 301 one by one and fastened by fastening screws 502. Fastening bolts A401 and fastening screws 502 are recessed and stored.

[0025] The electric heating core 2 serves as the heating element and is located inside the aluminum frame 3 between the aluminum plate 4 and the insulation plate 5. The two electric heating cores 2 in two adjacent modular heating units 1 are electrically connected. Since the aluminum plate 4 and the insulation plate 5 are detachably connected to the aluminum frame 3, it is convenient to inspect and maintain the electric heating core 2 in the future.

[0026] Multiple modular heating units 1 are arranged and combined to form a heating system, which is then covered on the wall. By connecting the power supply, the electric heating cores 2 in all modular heating units 1 are powered on. After the electric heating cores 2 are powered on, they generate heat, which is transferred to the aluminum plate 4 on the front side of the aluminum frame 3. The aluminum plate 4 can then transfer the heat into the indoor air, thus achieving wall heating. The aluminum plate 4 can be made of aluminum decorative panels, which not only beautify the wall but also help to distribute heat evenly.

[0027] Among them, the insulation board 5 is made of high-temperature resistant insulation materials, such as rock wool, ceramic fiber, glass wool, expanded perlite and aerogel. The insulation board 5 is set between the electric heating core 2 and the wall, which can reduce the loss of heat to the wall, reduce heat loss and improve heating efficiency. Example 2

[0028] Please see Figure 4 and Figure 5 This embodiment further explains the electrically heated inner core 2 in Embodiment 1, as follows: The electric heating core 2 includes a heating cable body 21 and a fiberglass mesh 22, both of which are located within the aluminum frame 3 and between the aluminum plate 4 and the insulation board 5. The heating cable body 21 is located in front of the fiberglass mesh 22 and extends in a serpentine shape. The specific extension shape of the heating cable body 21 can be selected according to the actual construction plan and is not limited to a serpentine shape. The heating cable body 21 uses a constant power heating cable as the core heating element. When powered on, it can generate stable heat under safe conditions, with a maximum heating temperature of 200℃ and a power per unit area of ​​600 watts per square meter, exhibiting efficient and stable heating performance.

[0029] The heat tracing cable body 21 is sewn and fixed to the fiberglass mesh 22 with a preset stitch spacing and sewing trajectory. The heat tracing cable body 21 is fixed to the fiberglass mesh 22 by the process of uniform sewing, forming a stable heating structure. The fiberglass mesh 22 not only supports the heat tracing cable body 21, but also has good insulation properties. The sewing and fixing method ensures that the spacing between the lines of the heat tracing cable body 21 remains unchanged under high temperature working environment, avoids deformation of the heat tracing cable body 21, and ensures the uniformity and stability of heating of each modular heating unit 1.

[0030] like Figure 6 As shown, the aluminum frame 3 has a long groove 31 on its side so that the two ends of the heat tracing cable body 21 can extend to the outside. Specifically, the aluminum frame 3 has a long groove 31 on all four sides. When the aluminum plate 4 is fixed to the front of the aluminum frame 3, a wire-passing space can be formed on the four sides of the aluminum frame 3 respectively, so that the heat tracing cable body 21 can be led out from the wire-passing space on the corresponding side of the aluminum frame 3 for wiring according to the actual construction plan.

[0031] like Figure 5As shown, the heat tracing cable body 21 has a male fork plug 211 at one end and a female fork plug 212 at the other end. By inserting the male fork plug 211 on one side of the heat tracing cable body 21 into the female fork plug 212 at the end of the adjacent heat tracing cable body 21, the two adjacent heat tracing cable bodies 21 can be electrically connected to realize the overall power supply of the heating system. Example 3

[0032] Please see Figure 3 , Figure 4 and Figure 7 The differences between this embodiment and Embodiment 2 are as follows: The modular heating unit 1 also includes a fixing component 6, which is used to fix the modular heating unit 1 to the wall. Specifically, the fixing component 6 includes a positioning block 61, an expansion bolt 64, and an expansion sleeve 65. The positioning block 61 has an end hole 62 on its front end face, and a through insertion hole 63 is provided on the inner end wall of the end hole 62. The expansion bolt 64 is matched and inserted into the insertion hole 63, and the screw end can be stored in the end hole 62. The expansion sleeve 65 is threadedly engaged with the expansion bolt 64.

[0033] In addition, the fiberglass mesh 22 has through clearance holes 221, the insulation board 5 has through fitting openings 51, and a rectangular frame-shaped insert shell 7 is fixed on the inner surface of the aluminum plate 4 for the positioning insert 61 to be matched and inserted. The insert shell 7 passes through the clearance holes 221 and fitting openings 51 in sequence and is flush with the outer surface of the insulation board 5. When the modular heating unit 1 is fixed to the wall, the rear end faces of the positioning insert 61 and the insert shell 7 are flush and both fit against the wall.

[0034] Secondly, the end hole 62 is an internally threaded hole, and the aluminum plate 4 is provided with a stepped hole 41. The stepped hole 41 is provided with a fastening bolt B42 that is compatible with the end hole 62. When the fastening bolt B42 is screwed into the end hole 62 for fastening, the screwing part of the fastening bolt B42 can be stored in the stepped hole 41. The end of the stepped hole 41 is also detachably provided with a cap 8, and the cap 8 is flush with the front surface of the aluminum plate 4.

[0035] The modular heating unit 1 is fixed to the wall using fixing component 6 at the following distances: According to the actual construction plan, implantation holes are made on the wall at the locations corresponding to the positions of each modular heating unit 1, and expansion sleeves 65 are inserted into each implantation hole respectively; After the expansion bolt 64 is inserted into the insertion hole 63, it is screwed into the expansion sleeve 65. The expansion sleeve 65 expands, which can fasten the positioning block 61 to the wall. The modular heating unit 1 is placed against the wall, and the positioning plug 61 is inserted into the insert shell 7. Then, the fastening bolt B42 is inserted into the stepped hole 41 and tightened into the end hole 62. Finally, the cap 8 is tightened onto the end of the stepped hole 41, thus achieving the fixed installation of the modular heating unit 1.

[0036] The above installation method enables the individual modular heating unit 1 to be detachable. During disassembly, the cap 8 is removed from the stepped hole 41 port, and the fastening bolt B42 is unscrewed from the end hole 62. The modular heating unit 1 can then be removed separately for inspection, maintenance or replacement of the internal heat tracing cable body 21, minimizing damage to the entire system and the wall surface. Example 4

[0037] This embodiment, based on the aforementioned embodiments, provides a heating temperature control solution, as detailed below: By installing a temperature sensor inside the aluminum frame 3 of one of the modular heating units 1 and electrically connecting the temperature sensor to an external thermostat, the heating temperature is monitored in real time using the temperature sensor, and the data is fed back to the thermostat. The thermostat automatically adjusts the working state of the constant power heating cable according to the set temperature value to achieve precise temperature control.

[0038] The temperature sensor and temperature controller use existing technology, and their specific structure and working principle will not be described in detail. Furthermore, the temperature sensor and temperature controller are not shown in the accompanying drawings of the instruction manual. Example 5

[0039] Based on the aforementioned embodiments, taking a residential wall heating project with a wall area of ​​20 square meters as an example, the specific configuration is as follows: The heat tracing body 21 is a constant power heat tracing cable with a rated power of 600 watts per square meter. Using an industrial sewing machine with a stitch spacing of 3 cm, the heat tracing body 21 is evenly sewn onto the fiberglass mesh 22 according to a pre-designed parallel sewing trajectory to form an electric heating inner core 2 with a size of approximately 1m × 1m. Adaptive male fork plugs 211 and female fork plugs 212 are installed at both ends of the heat tracing body 21. After testing, under a simulated high temperature environment of 200℃, the position of the heat tracing body 21 on the fiberglass mesh 22 did not shift significantly, and the spacing between the lines remained stable. The electric heating core 2 is stacked in sequence with the 3cm thick insulation board 5 and the 1mm thick aluminum plate 4, and fixed with the aluminum frame 3 to form an independent modular heating unit 1. During the wall installation phase, according to the wall layout, the modular heating units 1 are fixed to the wall sequentially, starting from the corner, using fixing components 6. The spacing between adjacent modular heating units 1 is controlled within 1mm. After physical fixing is completed, the male fork plug 211 and female fork plug 212 of adjacent modular heating units 1 are accurately plugged in to achieve circuit connection. Figure 1 As shown, the modular heating unit 1 uses 20 units, arranged in four rows with five units in each row, ultimately forming a heating system that can cover the entire 20-square-meter wall.

[0040] When the power is turned on and the thermostat is set to the target temperature of 22℃, the temperature sensor monitors the wall temperature in real time and feeds the data back to the thermostat. When the wall temperature is below 22℃, the thermostat controls the heating cable body 21 to increase the heating power; when the temperature reaches or exceeds 22℃, the heating power is reduced, thereby achieving a stable and comfortable heating effect, meeting the user's personalized temperature needs, saving energy, and improving the user experience.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
