Abstract
The present invention relates to a kind of single-ended electrical heating elements, including electrothermal tube outer tube, it is characterized in that: two-part insulant interstitital texture is set in the inner chamber of described electrothermal tube outer tube；This two-part insulant interstitital texture includes the insulant filled section of hot zone and the insulant filled section of cold end, filling-modified magnesia powder in the insulant filled section of cold end；Heating wire is set in the insulant filled section of described hot zone, the modified magnesium powder of cold end arranges cold pin.Filled high-temperature magnesia powder in the insulant filled section of described hot zone.Described one end of cold pin is connected with one end of heating wire, and the other end of cold pin is stretched out by the end of cold end.Single-ended electrical heating elements of the present invention, two sections of insulant interstitital textures are formed in the inner chamber of electrothermal tube outer tube, even if making electrical heating elements still have fabulous insulating properties under high power density and applied at elevated temperature operating mode, reduction of will not insulating because of dampness again was lost efficacy.
Description
Technical field
The present invention relates to a kind of single-ended electrical heating elements, the especially modified oxidized magnesium of a kind of employing is as cold end insulant
Single-ended high power or high-temperature electric heating element heater, insulating properties that electrical heating elements in life-time service keep excellent is effectively ensured
Energy.
Background technology
Existing electrical heating elements, when high power density or operation at high temperature, can only use high-temperature oxydation magnesium as insulation
Material, but high-temperature oxydation magnesium has high hydrophilic, easily absorbs the dampness in air, causes insulation to reduce, until losing
Effect.
When low power density or middle temperature operating mode used below, using modified oxidized magnesium, modified oxidized magnesium is by magnesium oxide
Having done modification so that it is have hydrophobicity, heating element heater will cause absolutely insulation to reduce inefficacy because of outside dampness.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of single-ended electrical heating elements, make electricity add
Thermal element, when high power density, operation at high temperature use, still has the insulating properties of excellence, and keeps excellent insulation for a long time
Performance.
The technical scheme provided according to the present invention, described single-ended electrical heating elements, including electrothermal tube outer tube, it is characterized in that:
Two-part insulant interstitital texture is set in the inner chamber of described electrothermal tube outer tube；This two-part insulant interstitital texture bag
Include the insulant filled section of hot zone and the insulant filled section of cold end, fill in the insulant filled section of cold end and change
Property magnesia powder；Heating wire is set in the insulant filled section of described hot zone, sets in the modified magnesium powder of cold end
Put cold pin.
Further, filled high-temperature magnesia powder in the insulant filled section of described hot zone.
Further, described one end of cold pin is connected with one end of heating wire, and the other end of cold pin is stretched by the end of cold end
Go out.
Single-ended electrical heating elements of the present invention, forms two sections of insulant in the inner chamber of electrothermal tube outer tube and fills knot
Structure, wherein i.e. high-temperature region, hot zone uses high-temperature oxydation magnesium, uses modified oxidized magnesium in cold-zone to heating element heater end, makes electricity add
Even if thermal element still has fabulous insulating properties under high power density and applied at elevated temperature operating mode, again will not be because of dampness
Insulation reduces lost efficacy.
Accompanying drawing explanation
Fig. 1 is the structural representation of single-ended electrical heating elements of the present invention.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1: described single-ended electrical heating elements includes electrothermal tube outer tube 1, heating wire 2, high-temperature oxydation magnesium powder 3, changes
Property magnesia powder 4, cold pin 5, hot zone A, cold end B etc..
As it is shown in figure 1, single-ended electrical heating elements of the present invention, including electrothermal tube outer tube 1, the inner chamber of electrothermal tube outer tube 1
One end is hot zone A, and the other end is cold end B(the most not hot zone), filled high-temperature magnesia powder 3 in the A of hot zone, at cold end B
Filling-modified magnesia powder 4；Heating wire 2 is set in the high-temperature oxydation magnesium powder 3 of described hot zone A, modified oxidized at cold end B
Magnesium powder 4 arranges the cold i.e. conducting rod of pin 5(), one end of cold pin 5 is connected with one end of heating wire 2, and the other end of cold pin 5 is by cold end
The end of B is stretched out.
The operation principle of the present invention: the present invention uses different materials respectively at the hot zone A and cold end B of electrothermal tube outer tube 1
Insulant, thus in the inner chamber of electrothermal tube outer tube 1 formed two sections of insulant interstitital textures, wherein hot zone A fill
High-temperature oxydation magnesium powder 3, cold end B(not hot zone) filling-modified magnesia powder 4, modified magnesium powder 4 plays electric insulation at cold end B
With the effect that isolation internal high temperature magnesia powder 3 absorbs external humidification, the effect that in reaching to use, electrothermal tube electric insulation is excellent.
