Description
Technical field
What the present invention relates to is a kind of electric heater, a kind of especially utilize working fluid cycles back and forth evaporation and condensation heat is delivered to the heat pipe type electric warmer that goes in the surrounding environment rapidly, belong to household electrical appliance technical field.
Background technology
Electric heater heating is a kind of convenient economical heating system that Modern Family generally adopts, and especially uses more at southern area.The electric heater pattern is various in the market, and electric heating installation using oil as medium, far infrared electric heater, halide torch electric heater, convection type electric heater, glassed steel electric heater etc. are arranged, and wherein electric heating installation using oil as medium has the not available advantage of other pattern electric heater.In the prior art, number of patent application is the electric heating installation using oil as medium in 99244364.4 patents of invention, is a kind of good electric heater scheme, and its advantage is: no forced convertion wind, peace and quiet; The flames of anger, moist, radiationless, no high light, security is good; Surface temperature is even, and temperature fluctuation is little, and the thermal efficiency is higher, and human body sensory is comfortable; Heating tube is sealed in the working media, and ingress of air is not difficult for oxidation, long service life.But the shortcoming of electric heating installation using oil as medium is also clearly, and its programming rate is slow, open heat that the back heating tube sends at first by its inner working media (conduction oil) absorb make conduction oil reach certain temperature after, just by fin space heat elimination towards periphery; Owing to 70% be full of working media (conduction oil) in its internal capacity, electric heating installation using oil as medium weight is big in addition.Number of patent application is 96232153.2 fast electric heating oil spit of fland patent of invention, is to have increased a blower fan in the electric heating installation using oil as medium structure, though this kind structure has improved programming rate, has certainly led to the decline of the noise problem and the thermal efficiency.
Summary of the invention
For deficiency and the defective that overcomes prior art, the present invention is designed to an all-in-one-piece heat-pipe apparatus with electric heater, made full use of heat-conduction principle and working fluid and realized the character that Rapid Thermal is transmitted, be delivered in the surrounding environment rapidly through the heat of heat pipe with heater by phase transformation.The present invention has possessed all advantages of electric heating installation using oil as medium, has remedied it simultaneously and has heated up slowly the shortcoming that weight is bigger.
The present invention is achieved through the following technical solutions.The present invention includes radiating tube, heater, heater shell, anti-dry copper mesh and bottom shell.Bottom shell and radiating tube are made the space of an integrally formed sealing, the inner working fluid that fills.The heater shell is enclosed within on the cylindrical heater, and the anti-dry copper mesh is wrapped on the heater shell, and the three forms heat generating component.Heat generating component is placed horizontally at the top of enclosure space inner bottom part housing, and an end and the bottom shell of heat generating component are affixed, and the power line of heater stretches out outside the housing.
After the heater energising, heat is passed to working fluid in the enclosure space by the heater shell, make the working fluid boiling rapidly, high-temperature steam moves upward along radiating tube, and in this process, steam is constantly by the lower tube wall condensation of temperature, the liquid that condensation forms flows back to the enclosure space bottom along tube wall under the gravity effect, in the environment around evaporation that so moves in circles and condensation, the phase transformation by working fluid are delivered to heat rapidly, reach the purpose that heats rapidly.Under the normal operating conditions, heat generating component is positioned at below the liquid level, under the situation that the heater heat flow density increases suddenly or the radiating tube condensing condition worsens suddenly, working fluid may be by excessive evaporation, make heat generating component partly expose liquid level, the effect of anti-dry copper mesh is exactly when above-mentioned situation occurring, utilizes capillary force that liquid is drawn onto on the heater shell, prevents dry combustion method.
The invention has the beneficial effects as follows, heat pipe type electric warmer work peace and quiet, the flames of anger, moist, radiationless, no high light, safety, surface temperature are even, and temperature fluctuation is little, thermal efficiency height, human body sensory is comfortable, starts simultaneously that programming rate is fast, in light weight, heat transfer property is good.Because it is simple in structure, metal consumption is economized, and makes it have reliable operation, easy to process, and is with low cost.Have remarkable economic efficiency and social benefit.

The specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described.
As shown in Figure 1 and Figure 2, the present invention includes radiating tube 1, anti-dry copper mesh 3, heater shell 4, bottom shell 5 and heater 6.Radiating tube 1 and bottom shell 5 all adopt same metal material such as stainless steel or copper and make one, form an enclosure space 2, fill working fluid in enclosure space 2.Heater shell 4 is processed the cylinder of end sealing by the good conductor of heat such as stainless steel, copper, aluminium, scribble electric insulation layer at heater shell 4 inner surfaces, heater shell 4 is enclosed within on the cylindrical heater 6, and anti-dry copper mesh 3 is wrapped on the heater shell 4, and the three forms heat generating component.Heat generating component is placed horizontally at the top of enclosure space 2 inner bottom part housings 5, one end and the bottom shell 5 of heat generating component are affixed, the power line 7 of heater 6 extends near enclosure space 2 bottoms behind anti-dry copper mesh 3 parcel heater shells 4 one circles outside fixed connecting end stretches out bottom shell 5 again.In enclosure space 2 liquid level 10 of the working fluid of institute's filling should be positioned at heat generating component above.Heater shell 4 separates heater 6 and working fluid, makes whole device safety and is easy to maintenance.One pair roller and a hold-down support are installed below bottom shell 5, convenient mobile and fixing.
As shown in Figure 3, Figure 4, the radiating tube cross sectional shape is an olive shape, and its inner surface also can be made into the shape of recessing 8 or has the pattern of imbibition core 9 except that smooth surface, and imbibition core 9 can adopt wire, wire netting or sintered metal materials to make.It is disconnected that groove 8 and imbibition core 9 can prevent that liquid film from being blown, and increases the liquid ability of returning of electric heater, and increase certain heat exchange area, improves the electric heater overall performance.
After heater 6 energisings, heat is passed to working fluid in the enclosure space 2 by heater shell 4, make the working fluid boiling rapidly, high-temperature steam moves upward along radiating tube 1, and in this process, steam is constantly by the lower tube wall condensation of temperature, the liquid that condensation forms flows back to the bottom of enclosure space 2 along tube wall under the gravity effect, in the environment around evaporation that so moves in circles and condensation, the phase transformation by working fluid are delivered to heat rapidly, reach the purpose that heats rapidly.Under the normal operating conditions, heat generating component is positioned at liquid level below 10, under the situation that heater 6 heat flow densities increase suddenly or radiating tube 1 condensing condition worsens suddenly, working fluid may be by excessive evaporation, make heat generating component partly expose liquid level 10, the effect of anti-dry copper mesh 3 is exactly when above-mentioned situation occurring, utilizes capillary force that liquid is drawn onto on the heater shell 4, prevents dry combustion method.
