Abstract
The invention relates to an electric heater band capable of being more stably attached to to-be-heated elements different in shape, the electric heater band comprises a shell body which is of a band-shaped structure. A plurality of protrusions are arranged in a side direction of the shell body. The section of each protrusion is in a isosceles trapezoid shape. Three electric heating wires which are distributed in a triangular shape are arranged in a cavity of each protrusion. An insulation layer wraps each electric heating wire. Epoxy resin is poured into cavities of the protrusions to take shapes.
Description
Technical field
The present invention relates to a kind of heat tape, belong to the electric heater technical field.
Background technology
Adopt in recent years Nie Chrome alloy sheet to be applied to existing production of electric boiling plate of electric heater, its heat efficiency is high, and thermal inertia is little, quick heating.But it is poor at the high-temperature condition stability inferior, its slab construction is difficult for fitting with the elements to be heated of various shapes, easily deforms, fracture etc. and affect operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of more stable heat tape that can fit with the element to be heated of various shapes for above drawback.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of heat tape, comprise housing, described housing is banded structure, and wherein said housing one side direction is provided with some projections, and described projection cross sectional shape is isosceles trapezoid, be provided with the electrical heating wire of three distributions triangular in shape in described projection cavity, described electrical heating wire outer cladding one layer insulating, in described projection cavity, casting epoxy resin is shaped, and described housing and projection intersection are arc-shaped structure, its arc radius is r, r=21.5mm.
Above-mentioned a kind of heat tape, wherein, the hypotenuse of described projection and housing molding angle a, a=28 °.
Above-mentioned a kind of heat tape, wherein, between described projection is 18-36mm apart from l.
Beneficial effect of the present invention is:
1. shell is provided with the projection of isosceles trapezoid, and between projection is 18-36mm apart from l, is provided with electrical heating wire in projection, buckling of shells can not affected to the shape of resistance wire, can not cause the resistance wire fracture and the generation potential safety hazard.
2. the electrical heating wire of Triangle-Profile, structure is the most stable, then pours into a mould with epoxy resin, and stability is better, and simultaneously, epoxy resin has certain elasticity, has increased the anti-extrusion performance of antidetonation.
3. housing and projection intersection are arc-shaped structure, avoid overflexing and make heat tape fracture, and here, projection two walls have played spacing effect.
4. while using, can be by two relative being used in combination of heat tape, heating effect is more remarkable.
The accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
Fig. 2 is installation diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of heat tape, comprise housing 1, described housing 1 is banded structure, wherein said housing 1 one side direction are provided with some projections 2, distance L between projection is 22mm, described projection 2 cross sectional shapes are isosceles trapezoid, the hypotenuse of projection and housing molding angle a, a=28 °, be provided with the electrical heating wire 3 of three distributions triangular in shape in described projection 2 cavitys, described electrical heating wire 3 outer cladding one layer insulatings 4, in described projection 1 cavity, casting epoxy resin is shaped 5, described housing 1 is arc-shaped structure with projection 2 intersections, its arc radius is r, r=21.5mm.
Beneficial effect of the present invention is:
1. shell is provided with the projection of isosceles trapezoid, and between projection is 18-36mm apart from l, is provided with electrical heating wire in projection, buckling of shells can not affected to the shape of resistance wire, can not cause the resistance wire fracture and the generation potential safety hazard.
2. the electrical heating wire of Triangle-Profile, structure is the most stable, then pours into a mould with epoxy resin, and stability is better, and simultaneously, epoxy resin has certain elasticity, has increased the anti-extrusion performance of antidetonation.
3. housing and projection intersection are arc-shaped structure, avoid overflexing and make heat tape fracture, and here, projection two walls have played spacing effect.
4. while using, can be by two relative being used in combination of heat tape, heating effect is more remarkable.
Here description of the invention and application is illustrative, not want by scope of the present invention restriction in the above-described embodiments, so the present invention do not limit by the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in protection range of the present invention.
Claims (3)
1. a heat tape, comprise housing, described housing is banded structure, it is characterized by, described housing one side direction is provided with some projections, described projection cross sectional shape is isosceles trapezoid, is provided with the electrical heating wire of three distributions triangular in shape in described projection cavity, described electrical heating wire outer cladding one layer insulating, in described projection cavity, casting epoxy resin is shaped, described housing and projection intersection are arc-shaped structure, and its arc radius is r, r=21.5mm.
2. a kind of heat tape as claimed in claim 1, is characterized by, the hypotenuse of described projection and housing molding angle a, a=28 °.
