Abstract
The invention discloses a high-efficiency infrared tungsten filament and a manufacturing method thereof. The existing tungsten filament is fragile and is apt to be broken, the thermal efficiency is low, the total radiation efficiency is low, the infrared radiation efficiency is low and the color temperature is high. The content of iron element in the tungsten filament provided by the invention is zero. Especially, the tungsten filament is wound to be a double-helix structure. During manufacturing and in the hydrogen annealing process of the tungsten filament, temperature-resistant mud is used for fully screening the internal part of a hydrogen annealing furnace to prevent the iron element from being exposed in a hearth. Especially, a molybdenum filament is used as a carrier during the winding of the tungsten filament. The tungsten filament provided by the invention has the advantages that the total radiation efficiency and the infrared radiation efficiency are greatly improved, and compared with common filaments, 30% of energy can be saved; the quantity of visible light is reduced, the light pollution is reduced and the use effect is greatly improved; since the energy conversion efficiency is improved, the heat in an infrared bulb is relatively reduced and the service life of the infrared bulb is improved; and the toughness of the filament is greatly improved, the service life of the bulb is greatly improved and a great number of manpower, material resources and social resources are saved.
Description
Technical field
The present invention relates to the manufacturing of tungsten filament, specifically is a kind of efficient infrared tungsten filament and manufacturing approach thereof.
Background technology
Infrared ray is a kind of in numerous invisible rays in the sunray.Ultrared wavelength is 0.75～1000 μ m greater than the wavelength of luminous ray on the solar spectrum.Infrared ray can be divided into three parts, i.e. near infrared ray, and wavelength is (0.75-1)～(2.5-3) μ m; Middle infrared (Mid-IR), wavelength are (2.5-3)～(25-40) μ m; Far infrared, wavelength are (25-40)～l000 μ m.
1993, it was the super bath of thermal source that Aopu Electric Appliance Co., Ltd., Hangzhou has invented with the infrared ray bulb, and from then on super bath enters into huge numbers of families as the standard configuration in modernized bathroom.Defectives such as the infrared ray bulb ubiquity heat efficiency on the market low (global radiation efficient and infrared radiation efficient are low), poor stability (glass bulb material and intensity difference), life-span weak point.
Summary of the invention
The technical problem that the present invention will solve and the technical assignment of proposition are to overcome the defective that existing tungsten filament embrittlement is easily broken, heat is imitated reduction, global radiation efficient is low, infrared radiation efficient is low, colour temperature is high, and a kind of efficient infrared tungsten filament and manufacturing approach thereof are provided.
For achieving the above object, efficient infrared tungsten filament of the present invention is characterized in that: the content of ferro element is 0 in the tungsten filament.
As the optimization technique measure, tungsten filament is turned to double-spiral structure.
For achieving the above object, the manufacturing approach of efficient infrared tungsten filament of the present invention is characterized in that: in the annealing in hydrogen atmosphere technology to tungsten filament, use heatproof mud that hydrogen-burning stove inside is shielded fully and avoid exposed ferro element in the furnace chamber.As the optimization technique measure, the carrier with molybdenum filament during as the coiling tungsten filament.
The invention has the beneficial effects as follows:
1. global radiation efficient and infrared radiation efficient improve greatly, compare with common filament, can practice thrift the energy 30%;
2. reduce visible light, reduced light pollution, improved result of use greatly;
3. because power conversion (radiation) efficient has improved, also reduced the inner heat of infrared bubble relatively, the useful life of having improved infrared bubble;
4. the toughness of filament improves greatly, has greatly improved the life-span and the service life of bulb, has practiced thrift great amount of manpower and material resources and social resources.
Embodiment
Below the present invention is further specified.
Efficient infrared tungsten filament of the present invention is: the content of ferro element is 0 in the tungsten filament, especially tungsten filament is turned to double-spiral structure.
The manufacturing approach of efficient infrared tungsten filament of the present invention is in the annealing in hydrogen atmosphere technology to tungsten filament, uses heatproof mud that hydrogen-burning stove inside is shielded fully and avoids exposed ferro element in the furnace chamber.Carrier when especially using molybdenum filament as the coiling tungsten filament.
The applicant was through development test and the checking in nearly 3 years; The result shows; If tungsten filament is in the annealing in hydrogen atmosphere technology of production process, low coverage is liftoff contact ironwork is then in the environment of hydrogen-burning stove HTHP; Part iron molecule has dissociated in the middle of the tungsten filament, and a littler part has wherein more generated iron oxide and tri-iron tetroxide with oxygen.And the iron molecule in the tungsten filament is to cause the main cause that the tungsten filament embrittlement is easily broken, heat is imitated reduction.Test shows, the wire broken rate of the bulb of being produced by the tungsten filament of iron molecule infiltration is 3-5 times of no iron molecule, and heat is imitated and lost at least 10%.So the applicant reforms through the production technology to tungsten filament, in the coiling engineering, traditional carrier iron wire is replaced with molybdenum filament; Hydrogen-burning stove inside is transformed, avoid iron material exposed in the furnace chamber, use heatproof mud that it is shielded fully.Like this, just can thoroughly stop the infiltration of iron molecule to tungsten filament.Thus, impermeable iron molecule inside the tungsten filament that guarantees to be produced.Use prolong greatly the useful life of the infrared ray bulb of this filament, heat is imitated and is improved significantly.
Traditional infrared ray bulb filament all adopts the single-screw coiling, the global radiation efficient that filament produced low (on average having only 52%), and infrared radiation is also just low simultaneously, and the colour temperature of single coil filament is very high, for about 2700K, can send dazzling high light.The global radiation efficient of the coiled coil filament after improving increases substantially (average 65%), and infrared radiation is far above single coil filament simultaneously, and colour temperature has been reduced to about 2400K, the minimum 1930K that reaches.
