Description

Hollow heat source
Technical field
The present invention relates to a kind of hollow heat source, relate in particular to a kind of hollow heat source based on CNT.
Background technology
Thermal source plays an important role in people's production, life, scientific research.Hollow heat source is a kind of of thermal source; Its characteristics are that hollow heat source has a hollow-core construction, heated material is arranged in this hollow-core construction hollow object is heated, therefore; Hollow heat source can heat each position of heated material simultaneously, and it is higher to heat wide, homogeneous heating and efficient.Hollow heat source successfully is used for industrial circle, scientific research field or sphere of life etc., like factory's pipeline, laboratory furnace or kitchen tools roaster etc.
The basic structure of hollow heat source generally includes substrate and is arranged on suprabasil electrothermal layer, produces temperature rising and then the heating object that Joule heat makes electrothermal layer through in electrothermal layer, feeding electric current.The electrothermal layer of existing hollow heat source adopts wire usually, forms through the mode of laying or twine like chromenickel wire, copper wire, molybdenum filament or tungsten filament etc.Yet adopt wire to have following shortcoming as electrothermal layer: one of which, wire surface are oxidized easily, cause local electrical resistance to increase, thereby blown, so useful life is short; Its two, wire is grey-body radiation, therefore, radiation efficiency is low, radiation length is short, and radiation is inhomogeneous; Its three, density of wires is bigger, weight is big, uses inconvenience.
For solving the problem that wire exists as electrothermal layer; Carbon fiber is because it has good black body radiation performance; The focus that advantages such as density is little become the electrothermal layer investigation of materials (sees also " DevelopmentForeground and Market Analyze of Carbon Fiber ", Wang Hai-ying, Hi-TechFiber&Application; Vol8, P765 (2007)).Carbon fiber is during as electrothermal layer, and the form with carbon fiber paper exists usually.Said carbon fiber paper comprises paper base material and is distributed in the asphalt base carbon fiber in this paper base material in a jumble.Wherein, paper base material comprises the mixture of cellulose fiber peacekeeping resin etc., and the diameter of asphalt base carbon fiber is 3～6 millimeters, and length is 5～20 microns.
Yet adopt carbon fiber paper to have following shortcoming as zone of heating: one of which, carbon fiber paper thickness is bigger, is generally tens microns, makes hollow heat source be difficult for making microstructure, can't be applied to the heating of microdevice.Its two owing to comprised paper base material in this carbon fiber paper, so the density of this carbon fiber paper is bigger, weight is big, make to adopt the hollow heat source of this carbon fiber paper use inconvenience.Its three flexible relatively poor because the asphalt base carbon fiber in this carbon fiber paper distributes in a jumble so the intensity of this carbon fiber paper is less, break easily, having limited it should have scope.Its four, the electric conversion efficiency of carbon fiber paper is lower, is unfavorable for energy-conserving and environment-protective.
In view of this, necessary a kind of hollow heat source is provided, this hollow heat source efficiency of heating surface is high, strength and toughness is big, the life-span is long, cost is lower, can be applicable to the both macro and micro device, and the practical application performance is good.
Summary of the invention
A kind of hollow heat source, it comprises: a hollow base; One zone of heating, this zone of heating is arranged at the surface of hollow base; And at least two electrodes, and said at least two electrode gap are arranged at the surface of zone of heating, and be electrically connected with this zone of heating respectively, wherein, described zone of heating comprises a carbon nanotube layer, and this carbon nanotube layer comprises the CNT of a plurality of mutual windings.
Compared with prior art, described hollow heat source has the following advantages: one of which, CNT can be processed the carbon nanotube layer of arbitrary dimension easily, both can be applied to macroscopical field and also can be applied to microscopic fields.Its two, CNT has littler density than carbon fiber, so, adopt the hollow heat source of carbon nanotube layer to have lighter weight, easy to use.Its three, the electric conversion efficiency of carbon nanotube layer is high, thermal resistivity is low, so this hollow heat source have heat up rapidly, thermo-lag is little, rate of heat exchange is fast characteristics.Its four, the CNT lack of alignment in the described carbon nanotube layer has good toughness, can bending fold becomes arbitrary shape and does not break, so have long useful life.
