Abstract
The utility model relates to an electric heating pipe, which is composed of a metal pipe sleeve 6, an alloy heating wire 3, a filler 4, an opening sealing materials 2, and an electrode outgoing line. The utility model is characterized in that one layer heat conducting insulating film 5 is arranged between the metal pipe sleeve 6 and the alloy heating wire 3, and the alloy heating wire 3 is appressed with the heat conducting insulating film 5. The utility model has the advantages of simple structure, good heat conducting property, electricity saving, and long service life.
Description
The utility model relates to a kind of electrothermal tube.
Electrothermal tube structure still is a traditional mode at present, generally is that the outside is overlapped with protection metal pipe with electrothermal alloy material spirally-wound heater element, and the intermediate gaps part is closely filled up crystal magnesium oxide, sees Fig. 1.The problem that this electrothermal tube mainly exists is that heater element and outer tube spacing are big, and is separated with magnesia powder, so the heat efficiency and thermal conduction effect are low, and the temperature difference of center heater element and metal tube shell is big, and the useful life of electrothermal tube is short.
The purpose of this utility model provides a kind of simple in structure, the high-efficiency long-life electrothermal tube of power saving, long service life.
The utility model is to realize like this, it is by the metal pipe box, if heating alloy within it, inserts, joint filling material and electrode outlet line are formed, it is characterized in that between metal pipe box and heating alloy, establishing one deck heat conducting insulating film, heating alloy and heat conducting insulating film are close to.
The utility model main points are that also described heat conducting insulating film can be mica paper or teflon cloth.
The utility model since between electric heating element and the sleeve pipe only every one deck lead insulation film, pyroconductivity is improved greatly, the temperature difference between electric heating element and sleeve pipe is also little, not only saves the energy and long service life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 2 is structural representations of the present utility model.
Referring to accompanying drawing 2, the utility model is a kind of high-efficiency long-life electrothermal tube, it is made up of metal pipe box 6, heating alloy 3, inserts 4, joint filling material 2 and the electrode outlet line 1 established within it, it is characterized in that establishing one deck heat conducting insulating film 5 between metal pipe box 6 and heating alloy 3, heating alloy 3 is close to heat conducting insulating film 5.Its heat conducting insulating film 5 general mica paper that adopt also can adopt teflon cloth, and purpose is to improve pyroconductivity.The enlarged diameter of electric heating element 3 as can be seen from Figure 2 of the present utility model many, so under the equal resistance, the used thermo electric material length of this element increases, respective cross-section is long-pending just to be increased; In addition between electric heating element 3 and the sleeve pipe only every one deck heat conducting insulating film 5, pyroconductivity is improved greatly, the accumulation of heat of electric heating element own is few, and and sleeve pipe between the temperature difference also little, not only save the energy, and prolonged useful life.
