Wherein the protruding density of protruding I11 lower extreme of group is greater than the protruding density of protruding I11 upper end of group, and the protruding density of protruding II 21 lower extreme of group is greater than the protruding density of protruding II 21 upper end of group. In this embodiment, the upper end of the protrusion group refers to an end of the protrusion group located below the center line of the metal strip in the width direction (i.e., the lower half), and the upper end of the protrusion group refers to an end of the protrusion group located above the center line of the metal strip in the width direction (i.e., the upper half). The protrusion density specifically refers to the number of protrusions of the upper half section or the lower half section of the metal strip in the width direction.
In the metal honeycomb heating body of the embodiment, the density of the protrusions at the lower end of the protrusion group I11 is high, and the density of the protrusions at the lower end of the protrusion group II 21 is high, so that the porosity of the lower end of the metal honeycomb heating body is lower, flame is effectively ensured to be more difficult to spread to the lower end of the honeycomb heating body to avoid backfire, and the flame stability is higher; in addition, protruding I11 of group and protruding II 21 upper ends of group of protruding density is little for honeycomb heat-generating body upper end has higher porosity, does benefit to the high-efficient burning of gas and burning exhaust emissions, and it is fast to generate heat, and the heating effect is better.
As shown in fig. 2-4, further, the protrusion group i 11 at least includes a first hollow protrusion 111 and a second hollow protrusion 112 alternately arranged along the length direction of the metal strip i 1, the upper end and the lower end of the first hollow protrusion 111 and the second hollow protrusion 112 have openings, wherein the opening at the upper end is an air outlet 102 forming a hole 101, the opening at the lower end is an air inlet 103 allowing gas to pass through, the length of the first hollow protrusion 111 is greater than that of the second hollow protrusion 112, so that the air outlet 102 and the air inlet 103 are arranged on the first hollow protrusion 111 and the second hollow protrusion 112, which is beneficial to further improving the overall porosity of the honeycomb heating element, so as to better satisfy the amount of gas required for combustion, and improve the heating effect.
Specifically, first fretwork is protruding 111 to be set up in the middle section of I1 width direction of metal band material, and second fretwork is protruding 112 to be set up in the half lower section of I1 width direction of metal band material. From this, the interval between the lower extreme of first fretwork arch 111 and the adjacent second fretwork arch 112 is little, and the interval between the upper end of first fretwork arch 111 and the adjacent first fretwork arch 111 upper end is big, effectively guarantees that the protruding density of the lower extreme of protruding group I11 is less than the protruding density of the upper end of protruding group I11.
Preferably, the height of the first hollow-out protrusions 111 is the same as that of the second hollow-out protrusions 112, so as to ensure that the coil with the protrusion group i 11 can form stable and uniform pores 101. The lower end of the second hollow-out projection 112 is flush with the lower end of the first hollow-out projection 111, so that the density of the lower end of the metal strip I1 is increased, and the pores at the lower end of the honeycomb heating body are reduced. In this embodiment, the protrusion height specifically refers to a height difference between a highest point of the hollow protrusion and a flat belt region of the metal belt material i 1 having the hollow protrusion.
More preferably, first fretwork is protruding 111 and second fretwork 112 for taking material I1 to the tensile formation of punching press outwards, and the upper and lower both ends of first fretwork is protruding 111 and second fretwork 112 and is taken material I1 cutting separation with the metal, forms gas outlet 102 and air inlet 103 respectively, so need not to increase the condition of consumptive material little, do benefit to the quick machine-shaping of first fretwork is protruding 111 and second fretwork is protruding 112, and the production efficiency is improved, and the manufacturing cost is reduced, ensures that the honeycomb heat-generating body has higher porosity simultaneously.

Therefore, the protruding density of the upper end of the protruding group II 21 is greater than that of the lower end of the protruding group II 21, so that the number of the protrusions at the lower half section of the metal strip material II 2 in the width direction is large, and the flame stability and the heating efficiency of the honeycomb heating body are improved; in addition, the arrangement of the air outlet 102 and the air inlet 103 enables the third hollowed-out protrusion 211 and the fourth hollowed-out protrusion 212 to form the air inlet 103, so that the third hollowed-out protrusion and the fourth hollowed-out protrusion can not only play a role of supporting reliably, but also serve as a part of the hole 101, the whole porosity of the honeycomb heating body is improved, primary air injection of the front-end nozzle is enhanced, and gas combustion is more sufficient.
Preferably, the third hollow-out protrusions 211 and the fourth hollow-out protrusions 212 are uniformly arranged in the same protrusion group ii 21, and the distance L1 is not less than twice the distance L2. In the present embodiment, the distance L1 is equal to twice the distance L2, and the third hollow protrusion 211 is coaxially disposed above the adjacent fourth hollow protrusion 212.
Specifically, the third hollowed-out protrusion 211 and the fourth hollowed-out protrusion 212 are respectively arranged at the upper half section and the lower half section of the width direction of the metal strip material II 2, so that the third hollowed-out protrusion 211, the fourth hollowed-out protrusion 212, the first hollowed-out protrusion 111 and the second hollowed-out protrusion 112 which are positioned on any two adjacent coil loops are staggered with each other in the vertical direction of the honeycomb heating element, and it is ensured that the hollowed-out protrusions between the adjacent coil loops are not mutually sunken, so that a more stable hole 101 is formed between each coil loop.
The third hollow-out protrusions 211 and the fourth hollow-out protrusions 212 have the same protrusion height, so that the coil with the protrusion group ii 21 can form uniform holes 101.
Preferably, the third hollowed-out protrusions 211 and the fourth hollowed-out protrusions 212 are formed by outwards stamping and stretching the metal strip material II 2, the upper ends and the lower ends of the third hollowed-out protrusions 211 and the fourth hollowed-out protrusions 212 are cut and separated from the metal strip material II 2, and the air outlets 102 and the air inlets 103 are formed respectively, so that the processing procedure is simplified, and the production efficiency is improved.
Example 2
The present embodiment is different from embodiment 1 in that: the lower ends of the first hollow-out protrusions 111 and the second hollow-out protrusions 112 are sealed, and the lower ends or the upper and lower ends of the fourth hollow-out protrusions 212 are sealed. The other portions were the same as in example 1.
It can be seen that, through all designing the lower extreme with first fretwork arch 111, second fretwork arch 112 and fourth fretwork arch 212 for sealed end to make the porosity of honeycomb heat-generating body lower extreme lower, further reduced the effective cross-sectional area that honeycomb heat-generating body lower extreme supplied the gas to pass through, it is faster to make the gas pass through the speed of honeycomb heat-generating body lower extreme, cool off honeycomb heat-generating body lower extreme better, and then make flame more difficult to propagate to honeycomb heat-generating body lower extreme, flame stability is higher, be difficult to take place the tempering more.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
