[0036] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, these 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 scope of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the several views and the detailed description.

[0037] The terms "one", "a", "an", "the", "said", are used to mean one or more of something; the terms "comprises", "comprising", "includes", "including", "has", "having", and the like, are used to mean including and to have one or more of something; and the term "consisting of" is used to mean including, and to have exactly one of something.

[0038] 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 a plurality of corrugated sections 12, the metal thin strip 1 is formed into a honeycomb body by coiling; wherein the air flow channels 10 are formed by the flat sections 11 and the corrugated sections 12, the air flow channels 10 are in a curved shape.

[0039] In the present application, a single layer of metal thin strip 1 with flat sections 11 and corrugated sections 12 is used, and the corrugated shape is formed by rolling or stamping. The flat sections 11 and the corrugated sections 12 surround each other to form the air flow channels 10, and each wave section on the corrugated sections 12 can serve as an air flow channel 10. By controlling the shape of the corrugated sections 12, the air flow channels 10 are in a curved shape, and the gas flows out in a curved shape, making the air flow more stable and the air flow velocity more uniform, which can form stable combustion of the flame on the surface of the gas outlet, effectively prevent backfire, and effectively improve the heat radiation of the honeycomb body and reduce backfire compared with straight fire holes. The gas flows out in a curved shape, making the air flow more stable and the air flow velocity more uniform, which can form stable combustion of the flame on the surface of the gas outlet, effectively prevent backfire. The air flow channels 10 are in a curved shape, which means that the corrugated sections 12 are arranged in a curved shape in the direction of the air 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.

[0040] In addition, the honeycomb body of the present application is formed by coiling a single layer of metal strip 1, and the metal strip 1 forms multiple coiled rings 100 after coiling, and the multiple coiled rings 100 are constrained with each other, the flat section 11 and the corrugated section 12 are constrained with each other, and the problem of local upward protrusion or downward movement does not occur, the honeycomb body is not easy to warp and cause tempering, the structure is simple and the cost is low.

[0041] The distribution of the flat section 11 and the corrugated section 12 on the single layer of metal strip 1 is divided into two kinds:

[0042] The first case is that the flat section 11 and the corrugated section 12 are connected alternately, and the one at the initial end of the metal strip 1 can be the flat section 11, so that 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. It can also be that the one at the initial end of the metal strip 1 can be the corrugated section 12 and then the flat section 11 is arranged, as long as the flat section 11 and the corrugated section 12 are arranged alternately. It should be noted that the initial end of the metal strip 1 of the present application is the side where the metal strip 1 is coiled, and the end is opposite to the initial end.

[0043] The second case is that the flat section 11 and the corrugated section 12 are not connected alternately, for example, the one at the initial end of the metal strip 1 can be the flat section 11, the second one is the corrugated section 12, the third one is still the corrugated section 12, the fourth one is the flat section 11, and the fifth one is still the flat section 11. This case is provided with one flat section 11 and one corrugated section 12 for one coiled ring 100. It can also be that the one at the initial end of the metal strip 1 can be the flat section 11, the second one is the corrugated section 12, the third one is still the flat section 11, the fourth one is the corrugated section 12, the fifth one is still the corrugated section 12, the sixth one is the flat section 11, the seventh one is the corrugated section 12, the eighth one is the flat section 11, and the ninth one is the flat section 11, and so on. Each coiled ring 100 has two flat sections 11 and two corrugated sections 12. Of course, when there are multiple flat sections 11 and multiple corrugated sections 12 on the coiled ring 100, the connection between the adjacent two coiled rings 100 is not that the flat section 11 and the corrugated section 12 are connected alternately, but that they are both the same shape, either both the corrugated section 12 or both the flat section 11.

[0044] By Figure 1 As shown in the honeycomb body, the honeycomb body also has multiple air outlet rings, and the present application utilizes the cooperation of the corrugated section 12 and the flat section 11 to make each wave section of the corrugated section 12 serve as an airflow channel 10, and the multiple airflow channels 10 are uniformly distributed along the air outlet ring and the honeycomb body, which not only ensures uniform air outlet, but also plays a role in stabilizing and uniformly distributing the airflow and reducing the generation of flue gas.

[0045] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc.

[0046] In a preferred embodiment of the present invention, the curved shape of the air flow channel 10 is one or more of an S-shape, a corrugated shape, an arc shape or a spiral shape.

[0047] like Figures 1-3 As shown, by providing an S-shaped, corrugated, arc-shaped or spiral air flow channel 10, the circulation time of the hot air flow of the gas in the air flow channel 10 is extended, and the heat exchange efficiency is greatly improved. In addition, the gas flows out through the curve, making the air flow more stable and the air flow velocity more uniform, so that the flame can form a stable combustion on the outlet surface, which can effectively prevent the occurrence of backfire.

[0048] The air flow channel 10 is curved, which means that the corrugations of the corrugated section 12 are arranged in a curve in the air flow direction. For example, an S-shape can enhance the strength of the metal strip 1, reduce the deformation of the honeycomb body, and make the performance of the honeycomb body more stable.

[0049] In the present application, the airflow channel on a metal strip 1 can be one or more of S-shaped, corrugated, arc-shaped or spiral-shaped, but the airflow channels 10 on the same annular air outlet area are the same. The airflow channels 10 on different annular air outlet areas may be different. For example, the honeycomb body is divided into an inner ring fire zone and an outer ring fire zone. The airflow channels 10 on the inner ring fire zone can be the same, and the airflow channels 10 on the outer ring fire zone can be the same as or different from the airflow channels 10 on the inner ring fire zone. For example, the airflow channel 10 on the inner ring fire zone is S-shaped, and the airflow channel 10 on the outer ring fire zone can be corrugated. By selecting airflow channels 10 of different shapes, the air outlet directions of the fire holes on the honeycomb body are also different to meet the needs of different burners.

[0050] In a preferred embodiment of the present invention, the corrugation of the corrugated section 12 is an arc wave, a triangle wave, a rectangular wave, a sine wave or a trapezoidal wave.

[0051] In a preferred embodiment of the present invention, the wavelength of the corrugations of the corrugated section 12 is 0.2 mm to 3 mm, and the wave height of the corrugations of the corrugated section 12 is 0.1 mm to 2 mm.

[0052] like Figures 1-3As shown, no matter whether the corrugated section 12 alone constitutes a coiled circle 100 or the flat section 11 and the corrugated section 12 jointly constitute a coiled circle 100, the corrugation on one corrugated section 12 is a regular-shaped band, and the corrugation can be an arc wave, a triangular wave, a rectangular wave, a sinusoidal wave or a trapezoidal wave. Preferably, the corrugation size on the same corrugated section 12 is consistent and centrosymmetric, so that the honeycomb body is beautiful, the process is simple, and the gas outlet holes are uniform. Generally, the corrugation size of the corrugated section 12 on the same gas outlet ring is consistent. The wavelength or wave height of the corrugation on different gas outlet rings can be different. For example, the gas outlet hole of the outer ring can be larger than that of the inner ring, and in some cases, the gas outlet hole of the inner ring can be larger than that of the outer ring to increase the central firepower.

[0053] Preferably, the wavelength of the present application is 0.2mm-3mm, and the wave height is 0.1mm-2mm. Within this range, the gas outlet is fast, the radiation heat transfer efficiency is high, and the performance of the honeycomb body is better.

[0054] In a preferred embodiment of the present application, the metal thin strip 1 is coiled to form a plurality of coiled circles 100, and the coiled circles 100 include two types, one of which is a first coiled circle 100a formed by coiling the flat section 11 once, and the other of which is a second coiled circle 100b formed by coiling the corrugated section 12 once.

[0055] The first coiled circle 100a and the second coiled circle 100b are alternately arranged.

[0056] Figure 1 As shown, the present application can coil the flat section 11 once to form a first coiled circle 100a, and coil the corrugated section 12 once to form a second coiled circle 100b. The outer circle of the first coiled circle 100a is provided with the second coiled circle 100b, the outer circle of the second coiled circle 100b is provided with the first coiled circle 100a, and so on, so that the first coiled circle 100a and the second coiled circle 100b are alternately arranged to form a honeycomb body. That is, each coiled circle 100 in the honeycomb body is a separate flat section 11 or corrugated section 12.

[0057] The innermost side of the honeycomb body can be the first coiled circle 100a or the second coiled circle 100b, Figure 1 As shown, the flat section 11 is used as the starting end of the metal thin strip 1, and after being coiled once, a first coiled circle 100a is formed. Then, the corrugated section 12 is coiled on the outer periphery of the first coiled circle 100a to form a second coiled circle 100b. Then, the next flat section 11 is coiled to be on the outer periphery of the second coiled circle 100b, and so on, so as to form a honeycomb body.

[0058] In addition, the flat section 11 is wound according to requirements, and only the length of the flat section 11 and the number of turns after winding need to be set before pressing. The honeycomb body can be calculated according to the size of the preset inner diameter and outer diameter of the honeycomb body, the thickness of the metal strip 1, and the wave height of the corrugated section 12. The lengths of the different flat sections 11 and corrugated sections 1212.

[0059] The first winding turn 100a and the second winding turn 100b of the present application are arranged alternately, and the plurality of waves on the corrugated section 12 can separate the space of the two adjacent first winding turns 100a into a plurality of uniform airflow channels 10, which can play a role of stabilizing and uniformly distributing the airflow.

[0060] In a preferred embodiment of the present application, the metal strip 1 is wound to form a plurality of winding turns 100, and the winding turn 100 includes a flat section 11 and a corrugated section 12. The outer side of the corrugated section 12 is the flat section 11 of the adjacent winding turn 100, and the outer side of the flat section 11 is the corrugated section 12 of the adjacent winding turn 100.

[0061] In a preferred embodiment of the present application, the flat section 11 and the corrugated section 12 in each winding turn 100 are at least one, respectively.

[0062] The metal strip 1 is wound to form a plurality of winding turns 100, and each winding turn 100 can simultaneously include a flat section 11 and a corrugated section 12. Without increasing the corresponding description of the drawings, each winding turn 100 has one flat section 11 and one corrugated section 12. Of course, two flat sections 11 and two corrugated sections 12 can also be arranged in each winding turn 100. Of course, the number of flat sections 11 and corrugated sections 12 on each winding turn 100 can also be three, four, five, six, eight, nine, ten, twelve, or even more, which is not limited in the present application.

[0063] As long as the outer turn of the flat section 11 on the adjacent winding turn 100 is the corrugated section 12, and the outer turn of the corrugated section 12 is the flat section 11, that is, the flat section 11 and the corrugated section 12 are alternately arranged from the inner turn to the outer turn, which ensures that the air outlets are uniformly distributed on an air outlet surface and ensures uniform air outlet. Here, the air outlet is the wave section on the corrugated section 12, and each wave can serve as an air outlet to ensure uniform air outlet, stable flame, and less smoke.

[0064] In a preferred embodiment of the present application, it also includes a ring body, wherein the metal strip 1 is wound on the outer periphery of the ring body 2.

[0065] The initial end of the flat section 11 can be connected to the outer periphery of the ring body, that is, the ring body is wrapped with a turn or a section of the flat section 11. Alternatively, the corrugated section 1212 can be directly wound on the outer periphery of the ring body, which can increase the overall strength of the entire honeycomb body.

[0066] In a preferred embodiment of the present invention, the corrugated section 12 includes a plurality of wave crests 121 and a plurality of wave troughs 122 ; and a transition section 101 is provided between two adjacent coils 100 .

[0067] like Figure 1 As shown, the corrugated section 12 includes a plurality of crests 121 and a plurality of troughs 122, wherein the crest near the starting end of the corrugated section 12 is the first crest, the trough near the starting end of the corrugated section 12 is the first trough, the crest near the end of the corrugated section 12 is the Nth crest, and the trough near the end of the corrugated section 12 is the Nth trough. In this application, the crest 121 is where the corrugation contacts the outer coil 100, and the trough 122 is where the corrugation contacts the inner coil 100.

[0068] In such Figure 1 In the honeycomb body shown, part of the transition section 101 is connected between the first crest and the Nth crest on the same corrugated section 12, and the remaining part of the transition section 101 is connected between the first trough and the Nth trough. An irregular quadrilateral is formed by connecting the adjacent first winding coil 100a and the second winding coil 100b through two transitions, the first crest and the Nth crest, and the first trough and the Nth trough. The quadrilateral can be used to coil the corrugated section 12 into a whole, and the corrugated section 12 and the planar section 11 can be tightly connected to form a whole, thereby avoiding the problem of warping of the honeycomb body.

[0069] exist Figure 1 In the honeycomb body shown, a transition section 101 is provided between two adjacent coils 100. Because the inner side of the coiled planar section 11 is in close contact with the outer periphery of the corrugated section 12 located on the inner circle, the first coiled coil 100 located on the inner side has the corrugated section 12 at the initial end and the planar section 11 at the end. When the planar section 11 is coiled toward the outer circle, it needs to coil from the trough 122 of the corrugated section 12 at the initial end to its crest 121, and continue to coil against the outer periphery of the corrugated section 12 to form the second coiled coil 100. Generally, the initial end of the second winding coil 100 is a flat section 11, and the end is a corrugated section 12. When the corrugated section 12 at the end of the winding coil 100 is wound to the third winding coil 100, the transition section 101 will be connected from the Nth wave peak of the corrugated section 12 at the end of the second winding coil 100 to the first wave valley of the corrugated section 12 at the initial end of the third winding coil 100. At the same time, the inner side of the transition section 101 will abut against the first wave peak of the corrugated section 12 at the initial end of the second winding coil 100. This cycle is repeated to form a tightly connected honeycomb body, thereby avoiding the problem of honeycomb body warping caused by local upward bulging (emerging) or downward movement.

[0070] A method for manufacturing a honeycomb body according to an embodiment of the present invention includes:

[0071] Select a metal strip 1, and determine the basic parameters of the prefabricated honeycomb body; determine the pressing parameters according to the basic parameters of the honeycomb body; according to the pressing parameters, press the metal strip 1 into a plurality of plane sections 11 and a plurality of corrugated sections 12, wherein the corrugated sections 12 are in a curve shape along the airflow direction; then the metal strip 1 is wound for multiple turns to form a honeycomb body.

[0072] In the present application, the pressing can be roller pressing, stamping or the like, as long as the plane section 11 and the corrugated section 12 can be formed on the metal strip 1 at the same time, wherein by designing the shape of the corrugated section 12, different curved gas flow channels 10 can be formed, such as Figures 1-3 The corrugated section 12 on the corrugated section 12 can be in an S shape, a corrugated shape, an arc shape or a spiral shape in the airflow direction, and the gas flows out in a curve, making the airflow more stable and the airflow velocity more uniform, which can make the flame form stable combustion on the surface of the gas outlet, effectively prevent the occurrence of backfire phenomenon, and also can 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.

[0073] In the present application, the gas flow channel on the metal strip 1 can be one or more of S shape, corrugated shape, arc shape or spiral shape, but the gas flow channels 10 on the same annular gas outlet area are the same. The gas flow channels 10 on different annular gas outlet areas can be different. For example, the honeycomb body is divided into an inner ring fire area and an outer ring fire area, the gas flow channels 10 on the inner ring fire area can be the same, and the gas flow channels 10 on the outer ring fire area can be the same as or different from the gas flow channels 10 on the inner ring fire area, such as the gas flow channels 10 on the inner ring fire area are S-shaped, and the gas flow channels 10 on the outer ring fire area can be corrugated. By selecting different shapes of gas flow channels 10, the gas outlet directions of the fire holes on the honeycomb body are also different to meet the needs of different burners.

[0074] The specific coiled structure of the honeycomb body is as follows: in the first case, the flat section 11 and the corrugated section 12 are alternately connected, for example, the initial end of the metal 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 is connected to the initial end of the next flat section 11, the end of the next flat section 11 is connected to the initial end of the next corrugated section 12, and so on. Meanwhile, the initial end of the metal 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 strip 1 of the present application is the side where the metal strip 1 is coiled, and the end is opposite to the initial end. In the second case, the flat section 11 and the corrugated section 12 are not alternately connected, for example, the initial end of the metal strip 1 can be a flat section 11, the second one is a corrugated section 12, the third one is also a corrugated section 12, the fourth one is a flat section 11, the fifth one is also a flat section 11, and so on. This case is provided with one flat section 11 and one corrugated section 12 for one coiled ring 100. Alternatively, the initial end of the metal strip 1 can be a flat section 11, the second one is a corrugated section 12, the third one is also a flat section 11, the fourth one is a corrugated section 12, the fifth one is also a corrugated section 12, the sixth one is a flat section 11, the seventh one is a corrugated section 12, the eighth one is a flat section 11, the ninth one is a flat section 11, and so on. Each coiled ring 100 has two flat sections 11 and two corrugated sections 12. Of course, when there are multiple flat sections 11 and multiple corrugated sections 12 on the coiled ring 100, the flat section 11 and the corrugated section 12 are not alternately connected at the connection between the adjacent two coiled rings 100, but are both the same shape, either both the corrugated section 12 or both the flat section 11.

[0075] The metal strip 1 is coiled multiple times by the device to form a honeycomb body. After the metal strip 1 is coiled, multiple coiled rings 100 are formed. Therefore, the honeycomb body of the present application is composed of multiple coiled rings 100 that are constrained to each other, and the flat section 11 and the corrugated section 12 are alternately connected, so that the honeycomb body does not have the problem of locally protruding upwards or moving downwards, is not easy to warp, is not easy to cause tempering, has a simple structure and low cost.

[0076] In a preferred embodiment of the present application, the basic parameters of the honeycomb body include the inner diameter of the honeycomb body, the size of the gas outlet hole and the gas outlet direction, and the pressing parameters include the length of the flat section 11, the length of the corrugated section 12, the shape of the gas flow channel 10 and the size of each wave in the corrugated section 12. According to the basic parameters of the honeycomb body and the thickness of the metal strip 1, the inclination angle of the corrugated section 12 and the size of each wave in the corrugated section 12 are determined.

[0077] Wherein, the basic parameters of the honeycomb body can be the inner diameter size of the honeycomb body a, the circumference of the coiled circle 100 S, the size of the gas outlet hole, since the gas outlet hole of the present application is equivalent to each wave of the corrugated section 12, so the size of the gas outlet hole is the wave height d and the wave length c of the corrugated section 12, in addition, assuming that the thickness of the metal strip 1 is b, the circumference of the i-th coiled circle 100 is S i , then:

[0078] S i = π [a + (i-1) (b+d)].

[0079] Wherein, i represents the number from inside to outside, the wave height is the height from the inside of the wave crest 121 to the lowest point of the wave trough 122, that is, the distance from the inside highest point of a wave crest 121 to the outer circumference of the flat section 11 located inside the wave.

[0080] The length of different coiled circles 100 can be calculated through the above process, when the flat section 11 and the corrugated section 12 are coiled one circle to form a coiled circle, then the length of different coiled circles 100 is the length of the flat section 11 and the corrugated section 12, assuming that the coiled circle 100 has m flat sections 11 and m corrugated sections 12 at the same time, then the length of the flat section 11 and the corrugated section 12 is S i / 2n, assuming that the corrugated section 12 is the initial end of the i-th coiled circle, then the initial position of the first corrugated section 12 of the i-th coiled circle is S i-1 , the terminal position is S i-1 +S i / 2m, the initial position of the second corrugated section 12 of the i-th coiled circle is S i-1 +S i / m, the terminal position is S i-1 +S i 3 / 2m, and so on. Therefore, the initial position of different corrugated sections 12 can be determined. Then according to the size of the gas outlet hole, the size of each wave in the honeycomb body can be determined. According to the gas outlet direction of the gas outlet hole in the honeycomb body, the shape of the flow channel 10 can be selected to match different gas outlet directions. According to the size of the gas outlet hole, the size of each wave in the honeycomb body can be determined.

[0081] Therefore, by inputting the above information into the control system, the control system can calculate and convert into the pressing parameters of the pressing equipment, that is, the system can match the length of different flat sections 11 and corrugated sections 12, and can also calculate the shape and size of the waves in the corrugated section 12, and select the shape of the flow channel 10, and then press the metal strip 1 according to these parameters.

[0082] The cooperation of the corrugated section 12 and the flat section 11 in the application makes the wave on the corrugated section 12 as the airflow channel 10, and the plurality of corrugated sections 12 are uniformly distributed along the honeycomb body, which ensures uniform air outlet and also plays a role in stabilizing and uniformly distributing the airflow and reducing the generation of flue gas.

[0083] In addition, the cross section of the honeycomb body can be circular, elliptical, triangular, rectangular, hexagonal, octagonal, dodecagonal, etc., which is not limited in the application.

[0085] In a preferred embodiment of the application, one of the first winding circle 100a or the second winding circle 100b is arranged at the innermost side of the honeycomb body.

[0086] Figure 1 As shown, the flat section 11 can be wound one turn to form a first winding circle 100a, the corrugated section 12 can be wound one turn to form a second winding circle 100b, the outer side of the first winding circle 100a is provided with the second winding circle 100b, the outer side of the second winding circle 100b is provided with the first winding circle 100a, and so on, and the plurality of first winding circles 100a and second winding circles 100b are alternately arranged to form the honeycomb body. That is, each winding circle 100 in the honeycomb body is a separate flat section 11 or corrugated section 12.

[0087] The innermost side of the honeycomb body can be the first winding circle 100a or the second winding circle 100b, Figure 1 As shown, the flat section 11 is the starting end of the metal thin strip 1, and after being wound one turn, the first winding circle 100a is formed, then the corrugated section 12 is wound on the outer periphery of the first winding circle 100a to form the second winding circle 100b, and then the next flat section 11 is wound to form the second winding circle 100b on the outer periphery of the second winding circle 100b, and so on to form the honeycomb body.

[0088] In addition, the flat section 11 can be wound multiple turns as needed, and only the length of the flat section 11 and the number of turns after winding need to be set before pressing. The length of the flat section 11 and the corrugated section 12 can be calculated according to the parameters of the predetermined inner diameter and outer diameter of the honeycomb body, the thickness of the metal thin strip 1, and the wave height of the corrugated section 12.

[0089] The first coiled circle 100a and the second coiled circle 100b of the application are arranged alternately, and the plurality of waves on the corrugated section 12 can separate the space of the two adjacent first coiled circles 100a into a plurality of uniform air flow channels 10, which can play a role of stabilizing and uniformly distributing the air flow.

[0090] In a preferred embodiment of the application, the lengths of the flat section 11 and the corrugated section 12 are such that each coiled circle 100 has both 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 coiled circle 100, and the outer side of the flat section 11 is the corrugated section 12 of the adjacent coiled circle 100.

[0091] Each coiled circle 100 can have one flat section 11 and one corrugated section 12, or each coiled circle 100 can have two flat sections 11 and two corrugated sections 12, and of course the number of flat sections 11 and corrugated sections 12 on each coiled circle 100 can also be three, four, five, six, eight, nine, ten, twelve or even more. The application does not limit this.

The system calculates the length of each flat section 11 and corrugated section 12 according to the relationship of different inner and outer diameters, and then inputs it to the control system. The control system controls the roll press to roll according to the set program, and then outputs the flat section 11 and the corrugated section 12 on a metal thin strip 1.

[0093] In the application, the outer circle of the flat section 11 on the adjacent coiled circle 100 is the corrugated section 12, and the outer circle of the corrugated section 12 is the flat section 11, that is, the flat section 11 and the corrugated section 12 are arranged alternately from the inner circle to the outer circle, which ensures that the air outlets are uniformly distributed on an air outlet surface and that the air is uniformly distributed. Here, the air outlet is the wave section on the corrugated section 12, and each wave can serve as an air outlet to ensure uniform air distribution, stable flame, and less smoke.
