Background technology

Temperature control equipment from general kitchen application is used to high-end science generally uses stratie in application.Most of heating element is the high-resistance metal electric wire, and for example nickel-chromium (nichrome) or tungsten are designed to be provided for heating required necessary resistance.The resistance of this heating element is by resistivity, cross-sectional area and the length decision of electric wire.The heat that heating element produces is by the electric current decision by this heating element.Generally speaking, heating element also comprises the cladding material as electric insulation and heat conductor.

The heat that stratie produces arrives heated object by conduction, convection current and/or radiant transfer.Conduction heat transfer depends on the direct contact between heating element and the heated object, and for example, the heat transmission from the electric furnace to the metal pan is transmitted by conduction basically.Convective heat transfer depends on fluid and flows and transmit heat, and for example, the convection current that the culinary art egg depends on current in the boiling water pot is delivered to egg by water from metal pan with heat.Overheated its density that causes of the water of pot bottom reduces, thus the liter waterborne in the bottom of a pan, and the water of these risings is given thermal energy transfer in the egg that floats in the water.On the contrary, colder and density is bigger at the water at pot top, therefore, the water at pot top can sink to the bottom of a pan.Thereby in this pot water, formed the convection current of current.Transfer of radiant heat depends on electromagnetic energy (for example light) heat is delivered to object from heating element.The bread part of for example, toasting in electric oven is heated by the heat from luminous heating element radiation.Radiation heating also is the mode that solar energy arrives the earth.In actual applications, find that these three kinds of thermaltransmission modes influence each other and often generation simultaneously.

The stratie that uses in various heating systems and use is better than for example based on the heating source that burns.Electrical heating elements does not produce harmful or suffocative smog.Electrical heating elements is by the signal of telecommunication and further can be precisely controlled by digital circuit.Electrical heating elements can be made multiple shape, its can under the thermal loss of minimum near object produce the heat of concentrating very much, it can produce heat, fluid under the situation that does not have oxygen, even inflammable fluid also can heat by designing stratie suitably.

Yet the stratie of current use has some shortcomings in this area.Therefore the element of Metal Substrate, particularly nichrome and tungsten, quality is more crisp, is not suitable for the application that need heat with the pliability heating element.In addition, in many products are used bigger thermal cycle and the brittleness of these materials will cause thermal fatigue.Other hardware, for example the copper base member has been brought bigger pliability.Yet if this application need resistive element changes or bending position, this resistive element will damage because of metal fatigue.The Metal Substrate stratie generally forms metal cords, and these elements cost an arm and a leg, the Temperature Treatment that demand is very high, and shape is limited.When breakage took place, this breakage was generally by due to the fatigue described above in addition, and so whole element can not use and must change.

With reference to accompanying drawing 1a and 1b, be the diagram of first preferred embodiment of the present invention, show below and several key character of the present invention is discussed.Referring now to Fig. 1 a, diagram is according to the stratie 12 of conductive loaded resin-based materials of the present invention, and this heating element 12 comprises the solid band 16 of conductive loaded resin-based materials, this solid band and power supply V _Heat14 connect.This conductive loaded resin-based materials has conductivity.By adjusting the correlative or the type of conductive material in the base resin, can easily adjust the volume resistivity of this material.The volume resistivity that the resistance value of this heating element 12 equals this conductive loaded resin-based materials multiply by the cross-sectional area of the straight length of this element divided by this element.Base resin material can be selected based on many factors, for example mechanical strength, flexible, outward appearance, anticorrosive/electrolyte, anti-flammability, chemical property, working properties, transparency/opacity, cost etc., and in using to the requirement of heat.For example, when selecting to be used for the material of given heating element, must consider the glassy state temperature or the maximum operating temp of the resin-based materials of mold moulding.According to the present invention, can use resistant to elevated temperatures base resin material, the material of the operation of 1000 ℃ of those abilities for example obtains the resistive element of the very high-temperature of conductive loaded resin-based materials.

In this example, element 12 is a U-shaped, thus electric current I _HeatFrom power supply V _Heat14 flow through top lead/terminal and bottom lead/terminals of flowing through are returned.Work as electric current I _HeatDuring conduction, according to I ²R, element 12 produces heat.Since the heat conductivility of this conductive loaded resin-based materials excellence, this I ²The thermal energy conduction of R is to the outer surface of this element.So depend on application and the environmental condition of putting into element 12, these heat energy can shift from element 12 by conduction, convection current or radiation.In this example, element 12 uses direct currents (DC), yet, when element 12 by effective supply lines energy supply for example in dwelling house or industry when installing, also can easily use alternating current (AC).

Cross-sectional view is shown in the lattice structure 16 of the network of conducting fibre in the base resin and/or powder among Fig. 1 a, and conducting fibre and/or powder network 16 be the surface of representation element 12 also, but for easy diagram, not shown in the top view.Heating element of the present invention 12 shown in Fig. 1 a does not have external insulation layer, that is to say, the object on element 12 surfaces or fluid could directly contact and become electric loop with conductive material a part is not in most of the cases wished so.Therefore, electrical

insulating material

18 and 20 can be formed on the conductive loaded resin-based materials 16, and promptly in second cross section 17, this electrical

insulating material

5th cross section

21 and 23, can on the conductive loaded resin-based materials surface, form metal level 24.In the 4th cross section 21, metal level 24 directly is formed on the conductive loaded resin-based materials 16.In the 5th cross section 23, electric insulation layer 25 at first is formed on the conductive loaded resin-based materials, forms metal level 27 again.The

metal level

24 or 27 that appends to heating element 12 has changed electricity, heat, vision and the surface characteristics of the composite construction that obtains.If this metal level 24 directly is formed on this conductive loaded resin-based materials 16, then metal level 24 can be by electroplating or coating formation.If the formation method is metal plating, then the resin-based structural material of this conductive loaded resin-based materials 24 should metal plating.The available metal layer is electroplated very many fluoropolymer resins, and for example, GEPlastics, SUPEC, VALOX, ULTEM, CYCOLAC, UGIKRAL, STYRON, CYCOLOY are some resin-based materials that can use metal plating.Metal level 24 can form by for example plating or physical vapor deposition.Similarly, if resin-based materials is used as the electrical insulating material 25 of the 5th cross section 23, but then resin-based materials 25 is preferably metal plating as mentioned above.Unshowned other selected embodiment comprises a plurality of insulating barriers, imbeds conductor and/or other structure in conductive loaded resin-based materials 16 or
