Description

Technical Field

[0001] This utility model relates to the field of graphene heating technology, specifically a spliced ​​graphite heater. Background Technology

[0002] Graphene, as an electrothermal coating, can be cured into a film with semiconductor properties through a chemical reaction. Electrodes are then fabricated at both ends of the film, and heating can be generated by applying electricity. Due to the non-toxic, harmless, safe, durable, and high-performance characteristics of graphene composite materials, their applications in production and daily life are becoming increasingly widespread. However, existing graphene heaters have the following drawbacks in practical use;

[0003] First, graphene is mostly integrally molded, and when a part is damaged, it can easily affect the overall heating effect, and the repair efficiency is low and the cost is high.

[0004] Secondly, most graphene heaters have a fixed height and a limited heating range. Therefore, a spliced ​​graphene heater is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a modular graphite heater. This device, through the assembly and cooperation of columns and individual graphite sheets, combined with the height difference adjustment of adjacent individual graphite sheets, can meet different heating requirements. This device can be quickly assembled like a "puzzle", which not only reduces manual welding / wiring errors and improves processing efficiency, but also enhances system stability and facilitates quick maintenance / replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a splicing graphite heater, comprising: a base plate; a plurality of columns arranged in a ring on the base plate and detachably installable; adjustable-height graphite sheet units inserted between adjacent columns, each graphite sheet unit comprising a graphite sheet plate, with graphene wedge-shaped clips extending from both sides of the graphite sheet plate; each column comprising a graphene column body, a rectangular groove formed on the graphene column body, and two slots formed on the graphene column body and communicating with the adjacent side of the rectangular groove, for inserting and assembling the graphene wedge-shaped clips on adjacent graphite sheet units.

[0007] Preferably, each of the graphite sheet plates has a first through groove on both sides.

[0008] Preferably, each of the graphite sheet plates also has a second through groove in the middle.

[0009] Preferably, the base plate is also provided with a ring of screw reinforcement structures corresponding to a plurality of columns. Each set of screw reinforcement structures includes two second screw holes opened at the bottom of the graphene column and communicating with the rectangular groove; a first screw hole opened on the base plate and corresponding to the two second screw holes; and a threaded groove opened on each graphene wedge-shaped clamp; and also includes two stud bodies. When the two stud bodies pass through the two first screw holes and the two second screw holes in sequence from bottom to top and are threadedly connected to the adjacent threaded groove, they are used for the reinforcement assembly of the column and the adjacent graphene sheet unit.

[0010] Preferably, the lower surface of the base plate is provided with grooves corresponding to several sets of first screw holes.

[0011] Preferably, the threaded groove extends a certain distance inside the corresponding graphene wedge-shaped clamp to accommodate the height adjustment of the graphite sheet monomer.

[0012] Preferably, each graphene column is further fixed with a graphene support block on one side near its bottom, and the graphene support block is flush with one of the slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the assembly and cooperation of columns and individual graphite sheets, combined with the height difference adjustment of adjacent graphite sheets, can meet different heating requirements. The assembly design not only ensures that the failure of a single graphite sheet does not affect the overall operation, but also improves system stability by allowing for quick repair / replacement without disassembling the entire heating system, directly replacing the faulty graphite sheet, thus significantly reducing repair time and costs. Furthermore, the quick assembly, like a "puzzle," reduces manual welding / wiring errors and improves production efficiency. Attached Figure Description

[0025] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figures 1 to 9 The present invention preferably provides the following technical solution: a splicing graphite heater, comprising: a base plate 111; a plurality of columns arranged in a ring on the base plate 111 and detachably installable; adjustable-height graphite sheet units inserted between adjacent columns, each graphite sheet unit including a graphite sheet plate 112, with graphene wedge-shaped clips 113 extending from both sides of the graphite sheet plate 112; each column including a graphene column 117, a rectangular groove 116 formed on the graphene column 117, and two slots 118 formed on the graphene column 117 and connected to the adjacent side of the rectangular groove 116, for inserting and assembling the graphene wedge-shaped clips 113 on adjacent graphite sheet units.

[0028] In this embodiment, several columns and several graphite sheet units are arranged in an alternating and circular pattern on the surface of the base plate 111, and the columns and their adjacent two graphite sheet units can be detached and installed. Specifically, the combination... Figure 1 , 2As shown in Figures 3, 4, and 5, the graphene column 117 for each pillar is detachably mounted on the surface of the base plate 111. A rectangular groove 116 on the graphene column 117 extends inward and connects to two slots 118. Figure 8 , 9 As shown, the graphite sheet 112 containing each graphite sheet unit has two ends that can respectively pass longitudinally through the slots 118 where the two adjacent pillars are located. Simultaneously, the graphene wedge-shaped clips 113 fixed at both ends are aligned with the graphene wedge-shaped clips 113 of their adjacent graphite sheet units, as shown. Figure 3 , 4 As shown in Figure 5, this is the first assembly method of this application;

[0029] The second assembly method of this application: The graphene wedge-shaped clamping strip 113 and its adjacent graphene wedge-shaped clamping strip 113 are assembled with an interference fit. When different heating requirements are encountered, the height difference between adjacent graphene sheet monomers can be adjusted. Specifically, in combination... Figure 1 , 2 As shown;

[0030] This process is simple in structure and convenient to operate. The assembly design not only ensures that the damage to a single graphite sheet does not affect the overall operation (e.g., if there is a circuit fault in a certain area, only that graphite sheet needs to be replaced), thus improving system stability, but also facilitates rapid repair / replacement. There is no need to disassemble the entire heating system; the faulty graphite sheet can be directly replaced, significantly reducing repair time and costs. In addition, local physical damage (such as scratches) will not spread to the entire heating surface, resulting in higher safety. Furthermore, it further simplifies the manufacturing process, enabling standardized module mass production, reducing the manufacturing difficulty and defect rate of complex large-size heaters. At the same time, it allows for rapid assembly like a "puzzle," reducing manual welding / wiring errors and improving production efficiency.

[0031] Furthermore, each graphite sheet 112 has a first through groove 114 on both sides; furthermore, each graphite sheet 112 also has a second through groove 115 in the middle.

[0032] Combination Figure 6 , 7 As shown, when a large graphene plate is energized, the current tends to flow along the edge of the low-resistance path, resulting in an uneven temperature phenomenon of "hot edges and cold center" due to the edge effect. Therefore, this application can artificially increase the current path length and resistance in the central area by setting the first through groove 114 and the second through groove 115, forcing the current to flow more evenly across the entire heating surface. At the same time, it has the function of absorbing expansion deformation and reducing internal stress concentration. This is a mature existing technology.

[0033] Example 2

[0034] As another embodiment of this utility model, the base plate 111 is also provided with a ring of screw reinforcement structures corresponding to a number of columns. Each set of screw reinforcement structures includes two second screw holes 119 opened at the bottom of the graphene column 117 and communicating with the rectangular groove 116; a first screw hole opened on the base plate 111 and corresponding to the two second screw holes 119; and a threaded groove 122 opened on each graphene wedge-shaped clamping strip 113; and also includes two stud bodies 121. When the two stud bodies 121 pass through the two first screw holes and the two second screw holes 119 in sequence from bottom to top and are threadedly connected to the adjacent threaded groove 122, they are used for the reinforcement and assembly of the column and the adjacent graphite sheet unit; furthermore, the lower surface of the base plate 111 is also provided with grooves 120 corresponding to a number of sets of first screw holes.

[0035] In this embodiment, combined with Figure 1 , 2 As shown in Figures 4, 7, 8, and 9, several screw reinforcement structures correspond one-to-one with several columns. Each screw reinforcement structure includes two first screw holes on the base plate 111, two second screw holes 119 in the lower part of the rectangular groove 116, and a threaded groove 122 on each graphene wedge-shaped clamp 113. The two first screw holes and the two second screw holes 119 are aligned one-to-one. When the graphene wedge-shaped clamps 113 containing adjacent graphene sheet units are joined together inside the rectangular groove 116, the threaded grooves 122 on the two graphene wedge-shaped clamps 113 are aligned with the first screw holes and the second screw holes 119. When the stud body 121 is passed through the groove 120, the first screw hole, the second screw hole 119, and the threaded groove 122 from bottom to top, the base plate 111, the columns, and the adjacent graphene sheet units can be fixed. This embodiment can realize reinforcement operation and improve the stability of assembly.

[0036] Furthermore, the threaded groove 122 extends a distance inside the corresponding graphene wedge-shaped clamp 113 to accommodate the height adjustment of the graphite sheet monomer.

[0037] To improve the stability of adjusting the height difference between adjacent graphene flakes, the threaded groove 122 and stud body 121 provided in this application can penetrate deep into the graphene wedge-shaped clamp 113 to adjust the height of the graphene wedge-shaped clamp 113. Figure 1 , 2 As shown in Figure 4.

[0038] Furthermore, each graphene pillar 117 is also fixed with a graphene support block 123 near its bottom, and the graphene support block 123 is flush with one of the slots 118 for supporting the graphene sheet monomer and improving stability.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0040] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
