Description

Technical Field

[0001] This utility model relates to the technical field of thermal radiation, and specifically to a heating device. Background Technology

[0002] Traditional heating devices primarily employ two structural designs: integrated and modular, fixed-assembly structures. While integrated heating devices offer advantages in terms of integrity and structural stability, their typically enclosed internal heat convection space leads to uneven heat distribution, potentially causing localized overheating or insufficient heat dissipation. This is particularly problematic in large-space heating applications, where the lower radiant efficiency of this design hinders rapid and uniform heating. Furthermore, integrated designs present maintenance difficulties; partial damage often necessitates replacement of the entire unit, increasing operating costs.

[0003] While modular heating devices offer some improvement in maintenance, their reliance on bolted or welded connections leads to cumbersome assembly and hinders flexible modular expansion. For example, bolted devices require specialized tools for disassembly and reassembly, and long-term use can result in loosening and corrosion of connectors, affecting safety and stability. Welded connections, on the other hand, make disassembly difficult, hindering future maintenance and component replacement. Furthermore, existing heating devices typically feature a limited heat dissipation area design and lack effective heat radiation enhancement structures, resulting in low heat transfer efficiency and poor performance in applications requiring high power output. These issues limit the applicability of heating devices in various fields, including industrial and household applications, necessitating a new, more efficient, flexible, and easy-to-maintain heating structure. Utility Model Content

[0004] This utility model proposes a heating device, which has a cavity on the heating body, and two or more heating tubes spaced apart inside the cavity. When the heating tubes heat up, the cavity forms a heat radiation convection cavity through heat emission and transfer, which increases the heating effect of the heating device. In addition, the heating body transfers heat outward during the heating process of the heating tubes.

[0005] Furthermore, the shape and size of the heating device can be flexibly adjusted by splicing multiple heating plates together to adapt to different application scenarios. Simultaneously, the cavity formed by the splicing effectively promotes heat convection and improves the uniformity of heat radiation. In addition, the addition of corrugated sections and snap-fit ​​connections further optimizes heat exchange efficiency and ease of assembly, meeting users' needs for efficient, energy-saving, and easy-to-maintain heating devices.

[0006] A heating device designed for this purpose includes a heating body with a cavity and heating tubes disposed on the inner side of the cavity. Two or more heating tubes are provided and distributed at intervals on the inner side of the cavity. The heating body has an annular or tubular structure. The cavity forms a thermal radiation convection cavity during the operation of the heating body.

[0007] The heating element includes a heating plate, and the inner and / or outer surfaces of the heating plate are provided with corrugated sections to increase the heat radiation heating area of ​​the heating element.

[0008] The heating plate is one in number, and the heating plate is a ring-shaped heating unit. The heating plate is a closed ring, or the ring-shaped heating plate has an opening that connects to the outside air and a cavity.

[0010] In the closed ring structure, there is a snap-fit ​​connection between two adjacent heating plates, and the two adjacent heating plates are connected by snap-fit ​​connection; or, the two adjacent heating plates are fixedly connected by riveting.

[0011] Alternatively, each heating plate has an opening, and when two adjacent heating plates are fastened together, they form a ring structure with gaps and not closed through the opening.

[0012] The snap-fit ​​connection includes a first snap-fit ​​disposed on one heating plate and a second snap-fit ​​disposed on another heating plate. The first snap-fit ​​and the second snap-fit ​​engage to make the two adjacent heating plates snap-fit ​​connected.

[0013] The number of heating plates is one, and the heating plate is a ring-shaped heating unit.

[0014] The cross-section of the heating element is circular, elliptical, or square.

[0015] The heating element includes a first heating plate and a second heating plate that are separated from each other, and the first heating plate and the second heating plate are fastened together to form a heating element with a circular, elliptical or square cross-section.

[0016] The heating element includes a first heating plate, a second heating plate, a third heating plate, and a fourth heating plate that are separated from each other. The third heating plate and the fourth heating plate are disposed between the first heating plate and the second heating plate. The first heating plate, the second heating plate, the third heating plate, and the fourth heating plate are fastened together to form a racetrack-shaped heating element.

[0017] The heating plate is provided with a receiving groove for installing and accommodating the heating tube; the heating tube is a round tube or a flat tube, and the heating tube is inserted into the receiving groove of the heating plate in a through-hole manner, forming a through-hole fitting connection between the heating tube and the heating plate, or the heating tube and the heating plate are connected by a clamp-type riveting fit.

[0018] The number of heating elements located inside the heating element is two or more, and the two heating elements are arranged at intervals facing each other.

[0019] The beneficial technical effects of this utility model are as follows:

[0020] By providing a cavity in the heating body, and providing two or more spaced heating tubes inside the cavity, when the heating tubes heat up, the cavity forms a heat radiation convection cavity through heat emission and transfer, which increases the heating effect of the heating device. In addition, the heating body transfers heat outward during the heating process of the heating tubes.

[0021] Furthermore, the shape and size of the heating device can be flexibly adjusted by splicing multiple heating plates together to adapt to different application scenarios.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] First embodiment:

[0033] See Figures 1-4 A heating device includes a heating body 1 with a cavity 3 and heating tubes 12 disposed inside the cavity 3. Two or more heating tubes 12 are provided and distributed at intervals inside the cavity 3. The heating body 1 has an annular or tubular structure. The cavity 3 forms a heat radiation convection cavity during the operation of the heating body 1.

[0034] By providing a cavity 3 on the heating body 1, and providing two or more heating tubes 12 spaced apart inside the cavity 3, when the heating tubes 12 heat up, the cavity 3 forms a heat radiation convection cavity through heat emission and transfer, which increases the heating effect of the heating device. In addition, during the heating process of the heating tubes 12, the heating body 1 transfers heat outward.

[0035] The heating body 1 includes a heating plate 2, and the inner and / or outer surfaces of the heating plate 2 are provided with corrugated sections 4 for increasing the heat radiation heating area of ​​the heating body 1.

[0036] The design of the corrugated section 4 significantly increases the surface area of ​​the heating plate 2, thereby improving the heat radiation efficiency. The heat radiation amount of the heating element 1. In this embodiment, the corrugated section 4 is arranged along the length (height) direction of the heating plate 2.

[0037] The number of heating plates 2 can be two or more, and they can be arranged in a closed or ring-shaped structure with an opening 14.

[0038] In the closed ring structure, a snap-fit ​​connection part 5 is provided between two adjacent heating plates 2, and the two adjacent heating plates 2 are connected by snap-fit ​​connection part 5; or, the two adjacent heating plates 2 are fixedly connected by riveting.

[0039] In the closed ring structure, a snap-fit ​​connection part 5 is provided between two adjacent heating plates 2, and the two adjacent heating plates 2 are connected by snap-fit ​​connection part 5; or, the two adjacent heating plates 2 are fixedly connected by riveting.

[0040] Alternatively, each heating plate 2 may have an opening 14. When two adjacent heating plates 2 are fastened together, they form a ring structure with gaps and not closed through the opening 14.

[0041] In this embodiment, each heating plate 2 has a plurality of openings 14 along the length of the snap-fit ​​connection part 5. The snap-fit ​​connection part 5 of each heating plate 2 is arranged vertically at intervals through the openings 14, forming a heating plate snap-fit ​​structure that is fixedly connected vertically.

[0042] Two adjacent heating plates 2 are connected by snap-fit ​​connectors 5. By splicing together two or more heating plates 2, a heating body 1 with a cavity 3 is formed. During the heating process of the heating body 1, the cavity 3 becomes a heat radiation convection cavity, significantly improving heat transfer efficiency. Compared with the traditional one-piece design, this structure is easier to assemble and disassemble. In addition, the air convection within the cavity 3 can accelerate heat diffusion, avoid local overheating, and extend the life of the device.

[0043] The snap-fit ​​connection part 5 includes a first snap-fit ​​6 disposed on one heating plate 2 and a second snap-fit ​​7 disposed on another heating plate 2. The first snap-fit ​​6 and the second snap-fit ​​7 are snapped together to make the two adjacent heating plates 2 snap-fit ​​connected.

[0044] The snap-fit ​​connection 5 enables quick engagement and disengagement of two adjacent heating plates 2, allowing for assembly or maintenance without tools. This design avoids the cumbersome operation of traditional bolt fixing while ensuring a stable connection that is not easily loosened even in high-temperature environments, thus balancing safety and convenience.

[0045] In this embodiment, each clip forms a locking groove with the corresponding heating plate 2. The mating structure of the first clip 6 and the second clip 7 achieves a tight connection through mechanical interlocking, preventing displacement of the heating plate 2 caused by thermal expansion and contraction. The optimized clip shape (such as barbs or elastic protrusions) can withstand repeated disassembly and assembly, reducing wear and making it suitable for high-frequency maintenance scenarios.

[0046] The cross-section of the heating element 1 is circular, elliptical, or square.

[0047] The closed-loop structure of the heating element 1 creates a uniform circulation of heat radiation, reducing heat loss. For example, a circular or ring-shaped design is suitable for central heating systems, achieving 360° heat dissipation without dead angles, and is particularly suitable for large open spaces.

[0048] The heating body 1 includes a first heating plate 8 and a second heating plate 9 that are separated from each other, and the first heating plate 8 and the second heating plate 9 are fastened together to form a heating body 1 with a cross-section of a circle, an ellipse or a square.

[0049] The heating plate 2 is provided with a receiving cavity 13 for installing and accommodating the heating tube 12; the heating tube 12 is a round tube or a flat tube, and the heating tube 12 is inserted into the receiving cavity 13 of the heating plate 2 in a through-type fitting connection. Alternatively, the heating tube 12 and the heating plate 2 are connected by a clamp-type riveting fit.

[0050] The heating plate 2 is provided with a receiving cavity 13 for installing and accommodating the heating tube 12. The receiving cavity 13 not only fixes the heating tube 12, but also enhances heat transfer through heat conduction through the cavity wall.

[0051] The heating element 1 contains two or more heating tubes 12, which are arranged opposite each other. The arrangement of multiple heating tubes 12 at intervals avoids localized high temperatures caused by heat superposition, and at the same time expands the radiation coverage area through the opposite distribution.

[0052] In this embodiment, the heating plate 2 is provided with screw slots 15 for engaging with screws. The heating plate 2 is fixed to the corresponding fastener by screws.

[0053] Second embodiment:

[0054] See Figure 5 The heating body 1 includes a first heating plate 8, a second heating plate 9, a third heating plate 10, and a fourth heating plate 11 that are separated from each other. The third heating plate 10 and the fourth heating plate 11 are disposed between the first heating plate 8 and the second heating plate 9. The first heating plate 8, the second heating plate 9, the third heating plate 10, and the fourth heating plate 11 are fastened together to form a racetrack-shaped heating body 1.

[0055] In this embodiment, the first heating plate 8, the second heating plate 9, the third heating plate 10 and the fourth heating plate 11 can all be provided with a receiving cavity 13 for installing the heating tube 12, and the outer surface of the first heating plate 8, the second heating plate 9, the third heating plate 10 and the fourth heating plate 11 can all be provided with corrugated sections 4.

[0056] Heating elements 1 are assembled by splicing together under different heating conditions.

[0057] Third embodiment:

[0058] See Figure 6 There is one heating plate 2. The heating plate 2 is a ring-shaped heating unit. The heating plate 2 is a closed ring, or the ring-shaped heating plate 2 is provided with an opening 14 that connects the outside air and the cavity 3.

[0059] The heating plate 2 has four opposing and spaced heating tubes 12 on its inner side.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
