Description
Technical field
The utility model relates to a kind of electric heater, is specifically related to a kind of at the electric heater that needs lower temperature or moderate temperature occasion to use, especially a kind of electric heater that is used for heating of house.
Background technology
At present, electric heater has been widely used in civilian and industrial circle.The electric heater that is used for heating of house can be divided into two kinds of direct heating and indirect by its mode of heating.Directly mode of heating is generally to adopt resistance wire, conductive film or the electric heating tube heating technology as thermal source; The indirect mode is to add media such as deep fat or water by electric heating element, again by the heating technology of media such as oil after the heating or water to indoor release heat.
In direct mode of heating, resistance wire is one of the most frequently used heater element, be wound into the class solenoid shape during use after, be installed in again on insulation, the heat-resisting strutting piece as heater.Because the useful life of this heater is limited, the efficiency of heating surface is low, and fail safe is relatively poor, and therefore this calandria is eliminated gradually.Conductive film is another kind of heater, mainly contains the coating type conducting film, coating type conducting film and metal conductive film etc.These conducting films have big, the efficiency of heating surface advantages of higher of area of dissipation.But also all there is shortcoming separately in this class conductive film.Shortcomings such as for example, there is the difficult control of resistance uniformity and consistency in the coating type conducting film, and usability is poor, and useful life is short; The complicated process of preparation of coating type conducting film, production efficiency is lower; The strip aluminium Electric radiant Heating Film that adopts the pyrolytic coating method on porcelain enamel substrate, to prepare, because aluminising place heating, the aluminising place does not generate heat, cause the heating film heating inhomogeneous, local temperature is higher, so this strip enamel film is very high to the requirement of enamel matrix, and this strip enamel Electric radiant Heating Film is also very high to the manufacturing technique requirent of heating film itself, thereby this warmer is not widely used always; With the electric heater of magnetron sputtering or the even lining conductive metal film of vacuum coating method large tracts of land on non-metallic substrate,, filming equipment low owing to production efficiency also fails to be popularized than reasons such as costlinesses always; Japan Patent 58-152794 discloses a kind of aluminium foil electric heating film, because this heating film has bubble to remain between encapsulation aluminium foil and the encapsulating material in the packaging by hot pressing process, heating film bubble in heating process can enlarge, simultaneously because the heat conductivility at bubble place is bad, cause the local temperature of aluminium foil to raise, cause be restricted the useful life of film.Electric heating tube as quartzy halogen lamp electric heating tube, adopts the mode of thermal radiation and light radiation to heat, because a part of electric energy changes into luminous energy in the heating process, causes the efficiency of heating surface lower.
In the indirect mode, electric heating element is realized the purpose that environment is carried out low-temperature heat by adding media such as deep fat or water.Though this mode of heating has fail safe preferably, still there are shortcomings such as firing rate is slow, the efficiency of heating surface is low.
The utility model content
Exist the life-span short or the efficiency of heating surface is low or the deficiency of poor stability in order to overcome the conventional electric heating device, the utility model provides a kind of electric heater, and this electric heater cost is low, life-span length, quick heating, efficiency of heating surface height, can realize low-temperature heat and heating of house.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of electric heater, it comprises backboard or framework, strutting piece, heat tape and wire clamp, and some strutting pieces are fixed on backboard or the framework, and heat tape is wrapped on each strutting piece successively, the two ends of heat tape are fixed on the wire clamp, again extracting power supply cord from the wire clamp.
Described heat tape can be the amorphous alloy strip, also can be the metal sheet band or the alloy thin band of other high resistivity.
Described some strutting pieces can divide upper and lower two rows to be fixed on backboard or the framework, last row and row's the alternate setting of strutting piece down, described heat tape successively from last row's a strutting piece around to arranging an alternate strutting piece down, around the next strutting piece to last row, so upper and lower back and forth being wound to wire clamp fixed again.
By thermodynamics basic law as can be known, heat is always passed to cryogenic object by high temp objects, and the area of dissipation of the temperature difference of heater element and heated medium and heater element is the key factor that influence heat is transmitted simultaneously.The temperature difference of heater element and heated medium is big more, helps heat transmission more; The area of dissipation of heater element is big more, helps heat transmission more.In order to improve the efficient that heat is transmitted, can realize by the temperature that improves heater element on the one hand, can realize by the area of dissipation that increases heater element on the other hand.The former requires heater element and strutting piece thereof to have good temperature resistance energy and antioxygenic property, this requirement always is subjected to certain restriction for the heater element of reality, some electric energy is converted into luminous energy when being operated in high temperature owing to heater element simultaneously, causes the efficiency of heating surface to reduce.Comparatively speaking, the latter is the effective ways that improve heat transference efficiency.Heat tape in the utility model is an amorphous alloy ribbon, it adopts the flash set technology preparation, the molten steel that is about to fusion is cast on the chill roll of high speed rotating by nozzle, it is the 20-30 micron that one step was made thickness, width can reach 200 millimeter, length can reach thousands of meters amorphous alloy ribbon, has advantages such as production technology is simple, the cost of material is low.Simultaneously, because the atomic arrangement of amorphous alloy is unordered, its resistivity is than high several times of corresponding crystalline state metal or alloy, even more than 10 times.Utilize the high surface area and the high resistivity of amorphous alloy ribbon can be made into resistance heating element efficiently,, and make it have good stability as heater element simultaneously because amorphous alloy has lower temperature coefficient of resistivity.Based on the advantage of above-mentioned basic principle and amorphous alloy ribbon, the technical solution of the utility model is to utilize amorphous alloy ribbon to construct a kind of electric heater as heater element, realizes low-temperature heat and heating of house.
