Description
Technical field
The utility model relates to a kind of PTC heating tape, relate in particular to a kind of temperature automatically controlled, profile is soft, reelable flexible PCT heating tape.
Background technology
The heating tape is applicable to heating, the insulation of jar, pipe, groove and other container of various industrial equipments; It mainly is made up of thermo electric material and insulating material etc., and thermo electric material is a nichrome alloy belt, and insulating material is the multilayer alkali-free glass fibre; Need configuration thermostat separately; Can directly be wrapped in the surface heating that is heated the position during use, there is certain potential safety hazard in this kind heating tape self-regulating performance, ageing-resistant and degree of crook is poor.
Existing a kind of by multiple conducting wires, addition type conducting polymer as exothermic material, the outer heating tape that constitutes by plastic insulating sleeve, need not to dispose in addition thermostat, it has certain PTC heating tape performance; But its complex structure synthesizes one as conductive core line by many parallel wires, but; This kind structural heat conducting is inhomogeneous, and sectional area is bigger, is unfavorable for bending repeatedly; The conductive core line that is made up of raw silk rings very easily fractures, and its range of application and pot life are restricted.
The utility model content
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and provide a kind of temperature automatically controlled, energy-conservation, profile is soft, the PTC ceramic thermal resistance heating tape of adjustable length, stable performance, long service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of flexible PCT heating tape; Comprise silica gel outer, PTC ceramic thermistor core sheet and aluminium strip; Its design feature is that PTC ceramic thermistor core sheet and aluminium strip are installed in the silica gel outer; Aluminium strip places the both sides of PTC ceramic thermistor core sheet, and aluminium strip contacts with silica gel outer, and aluminium strip is connected through conducting resinl with PTC ceramic thermistor core sheet.
The utility model PTC ceramic thermistor core sheet is a cuboid.
The advantage of the utility model has:
Temperature automatically controlled characteristic.The PTC ceramic thermal resistance is the semiconductor resistor that a kind of typical case has temperature sensitivity, and when surpassing certain temperature (Curie temperature), its resistance value is along with the rising of temperature is increasing of step evolution; At this moment; Because its resistivity-temperature characteristics, electric current reduces along with the increase of resistance, when resistance value reaches maximum; The PTC chip no longer generates heat, and temperature no longer rises; When temperature descended once more, electric current increased along with reducing of resistance, and the PTC chip generates heat once more, and so reciprocation cycle is to reach the constant temperature effect.The utility model utilizes its resistivity-temperature characteristics exactly, does not need the additional configuration thermostat.
Energy-conservation characteristic.When variation of ambient temperature, change like diurnal temperature, the power output of insulation belt can be made corresponding change, automatic constant-temperature with the variation of ambient temperature; Aluminium has conduction, heat conduction characteristic rapidly and uniformly, adopts aluminium strip as conduction, heat-conducting medium, optimizes the performance of PTC heating tape, and energy-saving effect significantly promotes.
Soft, reelable performance.Owing to self have the characteristic of insulation in the common silica gel, add existing heat-conducting filler, make it possess the dual performance of insulation, heat conduction.Adopt the overcoat of heat conductive silica gel material, increased its flexibility, increase the service life, adopt the hot strength of the PTC heating tape of silica gel outer to reach 400N, can overcome various operational environments through the experiment proof as the PTC heating tape.
Length-adjustable characteristic.Use the PTC chip mode parallelly connected to guarantee the stable operating voltage of each PTC chip, and stop the voltage decay, the purpose that length can be regulated arbitrarily in the certain-length scope with the aluminium strip of conductive and heat-conductive.
Stable performance, the characteristic of long service life.The PTC ceramic thermal resistance is an inorganic material, wide voltage power supply, and stable performance is difficult for wearing out, and silica gel has good high temperature resistant ageing resistace, and is safe and reliable.
