Description
The utility model belongs to the electroheat technology field, relates to the electric heating base components of utilizing the intrinsic resistance of nickel-base alloy to convert electrical energy into heat energy in ultrathin.
Electroheat technology is widely used in national economy all departments, the anti-dew defrosting device of the heating element of the heating register of the super clean work station that health conditions requiring is very high, camera, refrigerator for example, the special heating register of space flight, aviation, navigation, diving outfit, requirements such as chemical industry, oil, coal gas lose naked light and the requirement workplace of temperature adjustment etc. of heating, so its status is quite important.Existing electric heating element such as resistance wire, carbon rod, Elema, its volume, weight are big, fixing difficulty, be difficult to the workplace that is applied to the body complexity, vibrations are arranged, and power consumption is big, the life-span is poor, thermal inertia, thermal inertia value are very high in addition, and the efficient heat generation area is relatively very little, is difficult to realize accuracy control over temperature.Also have a kind of electric heating element to utilize plasma spray technology to make, yet,, had a strong impact on its useful life and result of use so heating is uneven because its sprayed surface is inhomogeneous.
The purpose of this utility model be to provide a kind of ultra-thin, light, the heat efficiency is high, on-the-spot mount scheme, reliable ultrathin electric heating base components, to satisfy the needs of national economy all departments.
The technical solution of the utility model is as follows: the utility model is made up of substrate 1, heating element 2, dielectric film 3, wherein heating element 2 is positioned on the substrate 1, and dielectric film 3 is positioned on the heating element 2, between substrate and the heating element, use adhesive 4 bonding in addition respectively between heating element and the dielectric film.
Gross thickness of the present utility model can change between the 0.4-2 millimeter.Above substrate, heating element, dielectric film adopt accurate hot calender technology to make finished product after bonding, have guaranteed the product thickness uniformity.The material of substrate 1 of the present utility model is a micarex, and through compaction process, has the good advantage of insulation, nickel-base alloy has the advantage that heating is fast, caloric value is big, the selection of dielectric film 3 has good heat conductivity, the advantage that insulation property are high, and adhesive 4 is selected the product Aug. 1st adhesive glue of Nanjing University for use, high bonding force is not only arranged, and can stand 300 ℃ the high temperature that sends after the nickel-base alloy energising and this temperature can be directed at working surface, thereby make the utility model can be competent at work on the spot, satisfied various requirements of holding hot equipment.
Advantage of the present utility model is as follows:
One, thin thickness, in light weight; It is laminar that the utility model is, and belongs to ultrathin type, produces in the unit interval under the identical heat prerequisite, and required weight is only for having the 1/2-1/10 of electric heating element.
Two, installation, easy to use: needn't add other edge edge materials during use, do not held hot equipment volume, weight, shape and limitation of field condition, promptly finish installation on the relevant device as long as the utility model is bonded in.Can distribute by the density of adjusting the nickel alloy circuit and " lead " self width thickness, fitting area to satisfy the needs that distinct device holds heat.
Three, pipe heat is evenly: the utility model adopts accurate heat pressing process to make, the thickness uniformity, so each point resistance value unanimity, heating is evenly.
Four, save raw material: compared with the prior art, produce in the unit interval under the identical heat prerequisite, metal consumption reduces 20-30%.
Five, because the thermal conductivity height of nickel-base alloy is 80 kilocalories/meter. the time. degree exceeds 3.4 times than the thermal conductivity of traditional electric heating nickel filament, so caloric value height and saves energy.Element itself heats up, cooling is sensitive, and its sensitivity is 8-12 times of nickel filament, thermal inertia, and thermal inertia is almost nil, and saves energy reaches 15-20%, and the heat efficiency improves 15%.
Six, anti-seismic performance is good, and the life-span is long: adopted particular adhesive hot-forming, among heater element the is closed in dielectric film high temperature resistant, not thermal resistance.So shockproof, not oxidation, the life-span can reach more than 100,000 hours.
Seven, applied range: the heating and the temperature adjustment that are widely used in Aeronautics and Astronautics, navigation, electronics, chemical industry, oil, instrument, measurement instrument industry and household electrical appliance, heating of house, super clean place.Its appearance causes the upgrading of thermo electric material, element, and the industrial technology design relevant with electroheat technology had far-reaching influence.
Provided embodiment of the present utility model in conjunction with following accompanying drawing:
Fig. 1 is the schematic diagram of the utility model vertical section.
Fig. 2 is after the utility model is thrown off dielectric film and adhesive, and the A of nickel-base alloy heating circuit is to schematic diagram.
Its outline of electric heating base components shown in Figure 2 is rectangular, to satisfy the needs of rectangular devices heating, also can satisfy the needs of cylindrical, corrugated device heating.According to by the geometry of heater, the needs of the design of multiple electric heating base components profile with satisfied scene can be arranged.Minimal thickness of the present utility model is 0.4 millimeter, and heating element thickness is 0.02 millimeter, and insulator film thickness is 0.01 millimeter, after bonding, because need pressure-sizing, so its gross thickness finally is 0.4 millimeter.According to on-the-spot needs, can adjust each element thickness flexibly, but gross thickness is no more than 2 millimeters after the pressure-sizing.The utility model should be coated with the Aug. 1st adhesive glue in the dielectric film outside on the equipment of being installed on the time, and is sticking with heat-barrier material such as asbestos in the substrate outside.
Wherein substrate 1 is to adopt the natural mica or the cloudier plate of compacting to make; Heating element 2 is to adopt the natural mica or the cloudier plate of compacting to make; Heating element 2 adopts nickel-base alloy to make, and the composition of this nickel-base alloy is by weight: nickel 97-99.5%, iron 1.5-0.2%, magnesium 1-0.15%, selenium 0.5-0.15%; Dielectric film 3 adopts polytetrafluoroethylene film to make, and also can adopt polyimide film to make, and also can adopt the rigidity mica insulation sheet to make.
