Technical field

It the utility model is related to electric-heating technology field, and in particular to a kind of electric heating fin.

Background technology

In traditional fin heats device, be it is overlapping in heating tube wear some fins and radiated, fin passes through punching The flanging bore of pressing formation coordinates with heating tube to be fixed, and to ensure the radiating effect of fin, multiple fins need uniform intervals to arrange, and Keep indeformable for a long time.Relatively thin fin good heat dissipation effect, but be easily deformed, influence its service life；Thus, existing thickness Degree is generally all bigger, can be for a long time using indeformable, but radiating effect is not good enough.

Utility model content

In view of the above-mentioned problems, the utility model proposes a kind of electric heating fin, there is less thickness and larger intensity, The radiating effect of fin can be effectively improved, and ensures its service life.

A kind of electric heating fin, including laminar fin body, the thickness of the fin body are 0.1-0.5mm, edge The length direction of fin body is provided with the reinforcement of stamped bumps, and the middle part of fin body is evenly arranged with along its length Multiple fixing holes, multiple distance pieces to stretch out are provided with the one side of fin body.

Above-mentioned electric heating fin thickness is smaller, by setting reinforcement to increase its intensity, it is used for a long time It is indeformable, it can also increase its area of dissipation to a certain extent；Multi-disc electric heating fin is located in heating by the way that fixing hole is overlapping Pipe keeps spacing in use, being supported between adjacent electric heating fin by distance piece, can fully ensure that the radiating of electric heating fin Effect, and Stability Analysis of Structures, service life are longer.

Preferably, the reinforcement is in outwardly triangular shape；In the polygon or circle of equivalent specifications, triangle Optimal stability, triangular shape is made in the section of reinforcement, its lifting effect to intensity can be maximized.

Preferably, the reinforcement has two, is symmetricly set on the both sides of fixing hole；Two reinforcement is symmetrical arranged, by force Degree is more preferable, and radiates evenly.

Preferably, the reinforcement is protruded from the opposing face of fin body with distance piece；Two-sided guiding air flow, dissipate Thermal velocity faster, also evenly.

Preferably, multiple distance pieces are symmetricly set on the both sides of fixing hole, and positioned at the outside of reinforcement；Electric heating The middle part of fin is strengthened by reinforcement, and outside is supported by distance piece and other structures or electric heating fin contacts, strengthens electricity The overall strength and stability of heating fin, ensures its service life.

Preferably, the fixing hole is provided with clamping part, and the clamping part is outside along hole center for the circumference from fixing hole Extend the annular flange formed；Fixation is contacted with heating tube by clamping part, the installation of electric heating fin is more firm.

Preferably, the clamping part is arranged on fin body the same face with distance piece；It is easy to one time punching molded, making It is more convenient.

Preferably, the thickness of the fin body is 0.2mm.

In summary, using the electric heating fin of above-mentioned technical proposal, there is less thickness and larger intensity, can have Effect improves the radiating effect of fin, and ensures its service life.

Embodiment

The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, the electric heating fin that the present embodiment provides, including laminar fin body 1, fin sheet The middle part of body 1 is evenly arranged with multiple fixing holes 2 along its length, is fixed to wearing in heating tube；The thickness of fin body 1 Spending can be with quick conductive and fully radiating for 0.1-0.5mm, less thickness；The length direction of fin body 1 is provided with punching It the reinforcement 3 that belling rises, can effectively strengthen the intensity of fin body 1, ensure that the time uses indeformable thereon；Fin body 1 One side on be provided with multiple distance pieces 4 to stretch out, support adjacent electric heating fin to keep spacing, ensure sufficiently radiating Space, it can also make the mutual attachment structure of the electric heating fin of multiple arranged superposeds more firm.

In the present embodiment, the thickness of fin body 1 is preferably 0.2mm, coordinates two and is symmetricly set on the both sides of fixing hole 2 Reinforcement 3, it can make to reach an effective balance between the intensity of fin body 1 and radiating effect, realize optimal use effect Fruit.Because in the polygon or circle of equivalent specifications, the optimal stability of triangle, so triangle is made in the section of reinforcement 3 Shape, i.e. reinforcement 3 are in outwardly triangular shape, and lifting effect of the reinforcement 3 to intensity is maximized.

Fixing hole 2 sets four, and corresponding, distance piece 4 divides eight both sides for being symmetricly set on fixing hole 2；Fixing hole 2 is set Clamping part 21 is equipped with, the clamping part 21 passes through folder to extend centrally out the annular flange to be formed from the circumference of fixing hole 2 along hole Hold portion 21 and fixation is contacted with heating tube, the installation of electric heating fin is more firm.Clamping part 21 protrudes from fin body with distance piece 4 On 1 the same face, and reinforcement 3 is protruded from the opposing face of fin body 1 with distance piece 4, is easy to two-sided guiding air flow, Radiating rate faster, also evenly, while facilitates one time punching molded, made more convenient.Distance piece 4 is preferably provided at reinforcement 3 outside, formed electric heating fin middle part strengthened by reinforcement 3, outside passes through distance piece 4 and other structures or electric heating The structure of fin contacts support, strengthen the overall strength and stability of electric heating fin, ensure its service life.

Above-mentioned electric heating fin thickness is smaller, good heat dissipation effect, increases its intensity by reinforcement, when alloing its long Between using indeformable, can also increase its surface area to a certain extent, can fully ensure that the radiating effect of electric heating fin, and tie Structure is stable, and service life is longer.

It should be noted that preferred embodiment above is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the utility model is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art should manage Solution：It can still modify to the technical scheme described in previous embodiment, either to which part or whole technologies Feature carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from the utility model reality The scope of a technical scheme is applied, it all should cover among claim of the present utility model and the scope of specification.
