[0041] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, the example embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the several views of the drawings, and description of the same will be omitted.

[0043] A honeycomb body according to an embodiment of the present application comprises a metal thin strip 1, the metal thin strip 1 comprises a plurality of flat sections 11 and corrugated sections 12 arranged alternately, the metal thin strip 1 is folded to form a plurality of folded layers 100, the plurality of folded layers 100 are stacked to form the honeycomb body, wherein the flat sections 11 and the corrugated sections 12 cooperate to form gas outlet holes 10 of the honeycomb body.

[0044] In the present application, a metal thin strip 1 having both flat sections 11 and corrugated sections 12 is used, and the metal thin strip 1 is rolled or punched to form regular corrugated shapes. The flat sections 11 and the corrugated sections 12 surround each other to form gas outlet channels, wherein each wave section on the corrugated sections 12 can serve as a gas outlet hole 10.

[0045] In addition, the metal thin strip 1 is folded in a serpentine shape to form a plurality of folded layers 100, the folded layers 100 abut each other and are stacked in sequence to form the honeycomb body, this processing method is simple and convenient to operate, and adjacent folded layers 100 are restrained from each other and are not prone to deformation. Of course, adjacent folded layers 100 can also be connected by welding or using sleeves or support plates to avoid deformation of the corrugated sections 12, so as to form uniform gas outlet holes 10, avoid tempering, achieve stable pressure distribution of airflow, and reduce the effect of flue gas.

[0046] The plane section 11 and the corrugated section 12 of the present application are alternately connected, no matter whether each plane section 11 and each corrugated section 12 is taken as a folding layer 100 respectively or the metal section with the plane section 11 and the corrugated section 12 is taken as a folding layer 100, as long as the same gas outlet section in the adjacent two folding layers 100 is composed of the plane section 11 and the corrugated section 12. Thus, the one at the initial end of the metal thin strip 1 can be the plane section 11, the end of the plane section 11 is connected to the initial end of the corrugated section 12, the initial end of the corrugated section 12 is connected to the initial end of the next plane section 11, the end of the next plane section 11 is connected to the initial end of the next corrugated section 12, and so on. Alternatively, the one at the initial end of the metal thin strip 1 can also be the corrugated section 12 and then the plane section 11 is arranged, as long as the plane section 11 and the corrugated section 12 are alternately arranged. It needs to be explained that the initial end of the metal thin strip 1 of the present application is the side where the metal thin strip 1 is wound, and the end is opposite to the initial end.

[0047] By Figure 1 As shown in the honeycomb body, the honeycomb body also has a plurality of gas outlet rings, and the present application utilizes the cooperation of the corrugated section 12 and the plane section 11, so that each wave section on the corrugated section 12 can be used as a gas flow channel 10, and the plurality of gas flow channels 10 are uniformly distributed along the gas outlet ring and the honeycomb body, so as to ensure uniform gas outlet and avoid tempering.

[0048] In a preferred embodiment of the present application, the end portions of the adjacent two folding layers 100 are directly connected.

[0049] In a preferred embodiment of the present application, the end portions of the adjacent two folding layers 100 are connected through a transition section 101.

[0050] As Figures 1-4 shown, the end portions of the two folding layers 100 can be directly connected, and can also be connected through a transition section 101. In a honeycomb body, the end portions of any adjacent two folding layers 100 can be directly connected (as shown in Figure 3 ), the end portions of any adjacent two folding layers 100 can be connected through a transition section 101 (as shown in Figure 4 ), or the end portions of part of the adjacent two folding layers 100 are directly connected and the end portions of the rest of the adjacent two folding layers 100 are connected through a transition section 101 (as shown in Figures 1-2 ). No matter which connection mode is adopted, as long as the end portions of any adjacent two folding layers 100 abut each other, the displacement deformation problem can be avoided.

[0051] In a preferred embodiment of the present application, the transition section 101 is a connecting plate, the transition section 101 and the adjacent two folding layers 100 surround to form a transition hole 102, and the gas outlet area of the transition hole 102 is smaller than the gas outlet area of the gas outlet hole 10.

[0052] As Figures 1-3 shown in the transition section 101 can be a vertical metal plate, that is, extending outward from the end of one folded layer 100 to the end of the next folded layer 100, realizing the reversing of the two folded layers 100. Taking two folded layers 100 as an example, the plane section 11 and the corrugated section 12 respectively, the transition section 101 extends vertically upward along the end of the plane section 11 to the end of the corrugated section 12, and can also be that the transition section 101 extends obliquely upward along the end of the plane section 11 to the end of the corrugated section 12, it should be noted that "out" here is based on the description of the drawings and is not used to limit the present application, and the oblique extension of the transition section 101 along the end of the plane section 11 means that the metal plate and the plane section 11 are arranged obliquely, and the included angle between the metal plate and the plane section 11 is an acute angle or an obtuse angle.

[0053] In addition, the transition section 101 can also be an arc-shaped plate, or even a bent plate, as long as it can match the shape of the predetermined honeycomb body, which is not limited in the present application. The transition section 101 can tightly connect the corrugated section 12 and the plane section 11 to form a whole, avoiding the problem of the honeycomb body being warped.

[0054] In addition, the transition section 101 and the plane section 11 and the corrugated section 12 connected thereto form a transition hole 102, and the gas outlet area of the transition hole 102 is smaller than that of the gas outlet hole 10, so as to prevent tempering.

[0055] In a preferred embodiment of the present application, each at least includes one of the plane section 11 and the corrugated section 12.

[0056] As Figure 1 shown, each folded layer 100 can include a plane section 11 and a corrugated section 12, and the number of plane sections 11 and corrugated sections 12 on each folded layer 100 is not less than 1, and can also be 2, 3, 4, 5, 6, 8, 9, 10, 12 or even more. The number of plane sections 11 and corrugated sections 12 on each folded layer 100 can be the same or different, as Figure 1 shown, some folded layers 100 have two plane sections 11 and one corrugated section 12, and other folded layers 100 have one plane section 11 and two corrugated sections 12, and of course other conditions are also possible, again without limitation, as long as in any adjacent folded layer 100 in the same gas outlet area, the plane section 11 is above the corrugated section 12, and the corrugated section 12 is above the plane section 11, so as to ensure that the gas outlet holes 10 are uniformly distributed on a gas outlet surface, and the gas is uniformly distributed.

[0057] Figures 2-4The plane section 11 is shown as the starting end of the metal thin strip 1 and forms the first folded layer 100 after being bent, then the corrugated section 12 is folded and abuts against the first folded layer 100, then the next plane section 11 is folded, and so on to form the honeycomb body. Of course, the starting end of the metal thin strip 1 can also be the corrugated section 12, as long as any two adjacent folded layers 100 are composed of the plane section 11 and the corrugated section 12. That is, each plane section 11 and each corrugated section 12 can be taken as one folded layer 100, because the plane section 11 and the corrugated section 12 are arranged alternately, thus after being bent in a serpentine shape, the outside of the plane section 11 is the corrugated section 12, the corrugated section 12 stacks the plane section 11, and so on to form the honeycomb body with uniform air outlet structure as shown in Figures 2-4 .

[0058] In a preferred embodiment of the present application, the projection of the honeycomb body along its axial direction is rectangular, triangular, circular, trapezoidal, hexagonal, octagonal or dodecagonal.

[0059] As shown in Figures 1-4 , the projection of the honeycomb body along its axial direction is rectangular, and the projection of the honeycomb body along its axial direction can also be understood as the cross section perpendicular to the air outlet direction of the honeycomb body. In the present application, the honeycomb body can also be circular, elliptical, triangular, rectangular, hexagonal, octagonal or dodecagonal. As long as it matches the shape of the burner head 2, the present application does not limit it.

[0060] In a preferred embodiment of the present application, the corrugation of the corrugated section 12 is arc-shaped wave, triangular wave, rectangular wave, sinusoidal wave or trapezoidal wave.

[0061] In a preferred embodiment of the present application, the wavelength of the corrugation of the corrugated section 12 is 0.2mm-3mm, and the wave height of the corrugation of the corrugated section 12 is 0.1mm-2mm.

[0062] In a preferred embodiment of the present application, the corrugation of the corrugated section 12 is arc-shaped wave, triangular wave, rectangular wave, sinusoidal wave or trapezoidal wave.

[0063] As shown in Figures 1-3 , the corrugation on the corrugated section 12 is a regular shape strip. The corrugation can be arc-shaped wave, triangular wave, rectangular wave, sinusoidal wave or trapezoidal wave. Preferably, the size and shape of the corrugation on the same corrugated section 12 are consistent and centrosymmetric, so that the honeycomb body is beautiful, the process is simple, and the air outlet holes 10 are uniform. Generally, the size of the corrugation on the same air outlet ring is consistent. The wavelength or wave height of the corrugation on different air outlet rings can be different. For example, the air outlet holes 10 of the outer ring can be larger than the air outlet holes 10 of the inner ring, and in some cases, the air outlet holes 10 of the inner ring can be larger than the air outlet holes 10 of the outer ring to increase the central firepower.

[0064] The preferred wavelength of the application is 0.2mm-3mm, and the wave height is 0.1mm-2mm. In this range, the gas outlet is fast, the radiation heat transfer efficiency is high, and the performance of the honeycomb body is better.

[0065] In a preferred embodiment of the application, the longitudinal section of the gas outlet hole 10 is in a curved shape.

[0066] By controlling the shape of the corrugated section 12, the gas outlet hole 10 is in a curved shape, the gas flows out in a curved shape, the gas flow is more stable, the gas flow velocity is more uniform, the flame can form stable combustion on the surface of the gas outlet, and the backfire phenomenon can be effectively prevented. Compared with the straight fire hole, this design can effectively improve the heat radiation of the honeycomb body and reduce backfire. 1, the gas flows out in a curved shape, the gas flow is more stable, the gas flow velocity is more uniform, the flame can form stable combustion on the surface of the gas outlet, and the backfire phenomenon can be effectively prevented. The gas outlet hole 10 is in a curved shape, which means that the corrugations of the corrugated strip 12 are arranged in a curved shape in the direction of the gas flow, which can strengthen the strength of the metal thin strip 1, reduce the deformation of the honeycomb body, and make the performance of the honeycomb body more stable.

[0067] Preferably, the curved shape of the gas outlet hole 10 is one or more of S-shaped, corrugated, arc-shaped or spiral-shaped. This design prolongs the circulation time of the hot gas flow in the gas flow channel 10, greatly improves the heat exchange efficiency, and in addition, the gas flows out in a curved shape, the gas flow is more stable, the gas flow velocity is more uniform, the flame can form stable combustion on the surface of the gas outlet, and the backfire phenomenon can be effectively prevented.

[0068] At the same time, the gas outlet hole 10 is in a curved shape, which means that the corrugations of the corrugated strip 12 are arranged in a curved shape in the direction of the gas flow, such as S-shaped, which can strengthen the strength of the metal thin strip 1, reduce the deformation of the honeycomb body, and make the performance of the honeycomb body more stable.

[0069] In a preferred embodiment of the application, the adjacent two folded layers 100 are connected by spot welding.

[0070] In a preferred embodiment of the application, a sleeve is provided on the outer periphery of the honeycomb body; or,

[0071] A plurality of support plates connected to each other are mounted on the outer periphery of the honeycomb body to press the honeycomb body.

[0072] As Figures 1-4In order to form an initial honeycomb body after the metal thin strip 1 is folded, at this time, the end portions of the two adjacent folded layers 100 are directly connected or connected through the transition section 101, in addition to the end portions of the two adjacent folded layers 100, the two adjacent folded layers 100 also abut each other, at this time, the abutment of each folded layer 100 needs to be welded, or the initial honeycomb body is fixed by using a sleeve matched with the shape of the honeycomb body, or four support plates connected with each other can be installed on the outer periphery of the initial honeycomb body to compress the initial honeycomb body, so as to prevent the honeycomb body from deforming and warping in the subsequent installation and use process.

[0073] The manufacturing method of the honeycomb body includes:

[0074] A metal thin strip 1 is selected, and the pressing parameters are determined; according to the pressing parameters, a plurality of alternating flat sections 11 and corrugated sections 12 are pressed on the metal thin strip 1; the pressed metal thin strip 1 is folded to form a plurality of folded layers 100, and the plurality of folded layers 100 are stacked to form a honeycomb body.

[0075] In the present application, the pressing can be roll pressing, stamping or the like, as long as the flat section 11 and the corrugated section 12 can be formed on the metal thin strip 1 at the same time. In addition, the flat section 11 and the corrugated section 12 are alternately connected, for example, the initial end of the metal thin strip 1 is a flat section 11, the end of the flat section 11 is connected to the initial end of the corrugated section 12, the initial end of the corrugated section 12 is connected to the initial end of the next flat section 11, and the end of the next flat section 11 is connected to the initial end of the next corrugated section 12, and so on. At the same time, the initial end of the metal thin strip 1 can also be a corrugated section 12, and then a flat section 11 is arranged, as long as the flat section 11 and the corrugated section 12 are alternately arranged. It should be noted that the initial end of the metal thin strip 1 of the present application is the side where the metal thin strip 1 is coiled, and the end is opposite to the initial end.

[0076] The metal thin strip 1 is folded into a honeycomb body by the device, and the metal thin strip 1 is coiled into a plurality of folded layers 100, so that the honeycomb body is composed of a plurality of mutually constrained folded layers 100, and the flat section 11 and the corrugated section 12 are alternately connected, so that the honeycomb body will not appear local upward bulging or downward movement problems, and is not easy to warp, is not easy to cause tempering, has a simple structure and low cost.

[0077] In addition, the cross-sectional view of the honeycomb body can be circular, elliptical, triangular, rectangular, hexagonal, octagonal, dodecagonal and various shapes, which are not limited in the present application.

[0078] In a preferred embodiment of the present application, the pressing parameters include the initial position and length of each planar section 11, the initial position, length and corrugation feature of each corrugated section 12, and the initial folding position, end folding position and folding direction of different folding layers 100.

[0079] Wherein, the corrugation feature includes the shape of the cross section of the corrugated section 12, the shape of the longitudinal section of the corrugated section 12, the wavelength and the wave height, according to the initial position and length of each planar section 11, the initial position and length of each corrugated section 12, a plurality of planar sections 11 and corrugated sections 12 that meet the requirements can be pressed on the metal strip 1.

[0080] Then according to the folding position of different folding layers 100, bending can be carried out. For example, when two folding layers 100 are point connected, the initial folding position of one of the two adjacent folding layers 100 and the end folding position of the other folding layer 100 will certainly coincide, so only need to fold at the position where the two folding layers 100 coincide according to the corresponding folding direction; when two adjacent folding layers 100 are connected through a transition section 101, each folding layer 100 has an initial folding position and an end folding position respectively, only need to fold at the corresponding folding position according to the corresponding folding direction.

[0081] In addition, the shape of the longitudinal section of the corrugated section 12 is the movement curve of the gas outlet direction of the gas outlet hole 10, which can be a straight line or a curve, such as S-shaped, corrugated, arc-shaped or spiral-shaped in the gas flow direction. The gas flows out through the curve, making the gas flow more stable and the gas flow velocity more uniform, which can make the flame form stable combustion on the surface of the gas outlet, effectively prevent backfire phenomenon, and also strengthen the strength of the metal strip 1, reduce the deformation of the honeycomb body, and make the performance of the honeycomb body more stable.

[0082] In a preferred embodiment of the present application, the folding layer 100 is divided into two types, one of which is a first folding layer 100a formed by the planar section 11, and the other is a second folding layer 100b formed by the corrugated section 12, and a plurality of first folding layers 100a and a plurality of second folding layers 100b are stacked to form a honeycomb body, wherein the first folding layer 100a and the second folding layer 100b are alternately arranged.

[0083] As shown in Figures 2-4 each planar section 11 and each corrugated section 12 respectively as a folding layer 100, so that the folding layers 100 on the honeycomb body can be divided into first folding layers 100a formed by the planar sections 11 and second folding layers 100b formed by the corrugated sections 12, and the first folding layers 100a and the second folding layers 100b are alternately arranged to form a honeycomb body with uniform gas outlet. Figures 2-4The shown flat section 11 is the starting end of the metal thin strip 1, and forms the first folded layer 100a after being folded, then the corrugated section 12 is folded and abuts against the first folded layer 100a to form the second folded layer 100b, then the next flat section 11 is folded, and so on to form the honeycomb body. Of course, the starting end of the metal thin strip 1 can also be the corrugated section 12, as long as any two adjacent folded layers 100 are composed of the flat section 11 and the corrugated section 12.

[0084] In a preferred embodiment of the present application, each folded layer 100 simultaneously has the flat section 11 and the corrugated section 12, and the outer side of the corrugated section 12 is the flat section 11 of the adjacent folded layer 100, and the outer side of the flat section 11 is the corrugated section 12 of the adjacent folded layer 100.

The number of the flat section 11 and the corrugated section 12 on each folded layer 100 can be the same or different, such as Figure 1 It is shown that some folded layers 100 have two flat sections 11 and one corrugated section 12, and other folded layers 100 have one flat section 11 and two corrugated sections 12, and of course other cases are also possible, and again are not limited, as long as in any adjacent folded layers 100 on the same gas outlet area, the upper side of the flat section 11 is the corrugated section 12, and the upper side of the corrugated section 12 is the flat section 11, to ensure that the gas outlets are uniformly distributed on a gas outlet surface, and to ensure uniform gas outlet.

[0086] Preferably, the different folded layers 100 can be welded at the positions, or the initial honeycomb body can be fixed by using a sleeve matching the shape of the honeycomb body; or four
