Abstract
The utility model discloses an embedded metal foil low-voltage heating strip, which belongs to a new product in the technical field of resistance consumption electricity for heating of electricity. An aluminium foil is used as an example for explaining the process. A thin (the thickness is 0.007 mm) aluminium foil is used as a heating resistance; the aluminium foil is sealed in insulating layers made of two layers of plastic thin films; the plastic films and the aluminium foil adopt the embedded process of bonding heating pressure (or stewing pressure). The resistance valve is calculated to determine the length and the width of the heating strip according to the outer voltage and the requirements of heating power. Then a satisfactory heating strip is formed after cut off. The embedded metal foil low-voltage heating strip has the advantages of lightness, thinness, flexibility, small resistance, large and even heating radiation range, simple manufacture, low cost, durability, etc. So the embedded metal foil low-voltage heating strip is suitable for low-voltage heat preservation materials, such as heating garments, curtains, wall paper, outdoor pipelines, etc.
Description
A kind of new material type product that belongs to the resistance heating power field on the electricity of this practical design.
At present, known resistance heating material mainly is the resistance of various alloys, as: modal heating wire.Because its quality soft or hard is crisp, sell off shape so be difficult for nest, easy fracture and radiating surface are little, thereby can't wrap up in naturally to invest and treat on the heat supply object.In addition, the report that adopts the vacuum coating mode to make the low pressure heater was arranged once also, its principle is that plastic film is sent into vacuum coating equipment, the metal vapors powder is fallen on the plastic film, but at every turn all as thin as a wafer, resistance is bordering on infinity, if want to make resistance to reduce, again and again plating repeatedly makes that metal vapors powder one deck is stacked to fall up, therefore, not only cost is very high, and when passing in and out in the vacuum furnace repeatedly, plastic film constantly hardens, and makes final products easy fracture, electric leakage.
The purpose of this utility model provides a kind of multiple film metal forming low pressure heating tape, and it can not only the large tracts of land Homogeneouslly-radiating, and the quality softness, and arbitrarily nest is rolled over, and safety durable is particularly suitable for human body heating next to the shin.
The purpose of this utility model is achieved in that the very thin metal forming of employing is as heating resistor, the metal forming two sides is being answered with chemical adhesion, hot pressing or stewing method of pressing and is being gone up insulation film as the surface insulation material, like this, just can be according to the resistivity of metal, by selecting the thickness of metal forming, its length and width degree of cutting obtains having the heating tape of desired resistance.Because metal forming (be commonly called as: tinfoil) and the quality of insulation film all very soft, arbitrarily nest is rolled over, so multiple film metal forming heating tape has same property naturally, simultaneously, because trilaminate material is combined with each other securely, it is durable to make it tension, thereby can make the people cosily be used for heating next to the shin, and it is antifreeze to reach house and yard piping.
Owing to adopt such scheme, can be in heating power, lighter, soft, twine in treating on the heat supply object naturally, and easy fracture not, safety durable, radiating surface is big, makes simply, and is with low cost.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a side-looking structure chart of the present utility model.
Fig. 2 is the multiple membrane process figure that makes multiple film metal forming low pressure heating tape.
1. insulation films, 2. metal formings, 3. adhesives, 4. compound nip drums among the figure
In Fig. 1, insulation film (1.) is being answered in the both sides of metal forming (2.) becomes one, constitutes the utility model.
In Fig. 2, the insulation film (1.) that scribbles adhesive (3.) divides and upper and lower metal forming (2.) to be clipped in the middle, and by the use of compound nip drum (4.), forms multiple film metal forming low pressure heating tape.
Claims (2)
1, multiple film metal forming low pressure heating tape, a kind of heating power material, it is characterized in that: inner heat resistance is the metal forming with certain length and width and thickness, and the insulated part on its two sides is an insulation film, between adopt chemical adhesion, hot pressing or stewing compression technology to be composited.
2, multiple film metal forming low pressure heating tape according to claim 1 is characterized in that: the appended insulation film in metal forming two sides can adopt pressure-resistant plastic, paper, fabric, insulating varnish and other to have the soft megohmite insulant of certain heat-sinking capability.
