Abstract
The utility model relates to a silicon carbide rod, and provides a spiral-type silicon carbide rod with high heat dissipation efficiency. The spiral-type silicon carbide rod comprises a heating section, the rod body of the heating section is provided with a band-shaped external surface spirally extending along the length direction of the rod body, and a set interval is disposed between two adjacent spiral loops on the band-shaped external surface. By adoption of the technical scheme, heat inside the heating section can be dissipated through each set interval disposed between two adjacent spiral loops on the band-shaped external surface, heat dissipation is fast, and the heat dissipation efficiency is high.
Description
Technical field
The utility model relates to Elema.
Background technology
Elema is to be primary raw material with the green hexagonal carborundum of high-purity, by certain material ratio processing base, bar-shaped, the nonmetal high-temperature electric heat element of tubulose made through 2200 ℃ of high temperature silication recrystallization sintering.In oxidizing atmosphere, normal serviceability temperature can reach 1450 ℃, and use can reach 2000 hours continuously.Because Elema serviceability temperature is high, there is high temperature resistant, anti-oxidant, corrosion-resistant, quick heating, the feature such as the life-span is long, high temperature deformation is little, installation and maintenance are convenient, and there is good chemical stability, now be widely used in the high-temperature fields such as electronics, magnetic material, powder metallurgy, pottery, glass, semiconductor, analytical test, scientific research, become the electrical heating elements of tunnel cave, roller kilns, glass furnace, vacuum furnace, Muffle furnace, smelting furnace and all kinds of firing equipments.
In prior art the barred body of Elema comprise column heating section, with two cold junctions that corresponding ends conduction connects of heating section, during use, two cold junctions respectively with the two poles of the earth conducting of power supply, thereby make electric current be produced heat and be distributed towards periphery by heating section, still, barred body corresponding to heating section of the prior art is column, during energising, the inner heat producing of barred body cannot directly be dispersed into outside barred body, therefore radiating efficiency is low, and body of heater is inner to heat up slowly, has affected production efficiency.
Utility model content
The purpose of this utility model is to provide the spiral type Elema that a kind of dissipation of heat efficiency is high.
The technical scheme that the utility model spiral type Elema adopts is: spiral type Elema, comprise heating section, the barred body of described heating section has the banded outer surface extending in the shape of a spiral along barred body length direction, has the interval of setting between the adjacent two circle spirals of described banded outer surface.
The spiral of described banded outer surface is single-screw.
Described heating section is tubulose, and described interval is to form by running through tube wall helical form gap radially.
Described interval is that the helical groove being formed on barred body by two adjacent circle spirals of banded outer surface forms.
The utility model spiral type Elema adopts technique scheme, the barred body of described heating section has the banded outer surface spirally extending along barred body length direction, two circles that described banded outer surface is adjacent have the interval of setting between spirals, therefore, the heat of heating intersegmental part can come out by having the interval of setting between two adjacent circle spirals of banded outer surface, rapid heat dissipation, radiating efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment mono-of the utility model spiral type Elema;
The name that in figure, each Reference numeral is corresponding is called: 11 heating sections, 12 cold junctions, 13 banded outer surfaces, 14 helical form gaps.
Fig. 2 is the structural representation of the embodiment bis-of the utility model spiral type Elema.
The name that in figure, each Reference numeral is corresponding is called: 21 heating sections, 22 cold junctions, 23 banded outer surfaces, 24 helical grooves.
Embodiment
The embodiment mono-of the utility model spiral type Elema as shown in Figure 1, it is a kind of linear Elema, barred body is tubular structure, comprise and be arranged on the cold junction 12 at length direction two ends and the heating section 11 between two cold junctions 12, the barred body of heating section 11 has the banded outer surface 13 extending in the shape of a spiral along barred body length direction, between the adjacent two circle spirals of banded outer surface 13, have and run through tube wall helical form gap 14 radially, thereby form the interval of setting size, now heating section 11 parts corresponding to banded outer surface 13 are equivalent to a spiral that the shoestring that cross section is rectangle is twisted into.
After the cold junction 12 of linear Elema powers up, electric current passes through from spiral shape structure, and heating section 11 produces heat, and inner heat can be dispersed into rapidly outside by helical form gap 14, has improved radiating efficiency.
The embodiment bis-of the utility model spiral type Elema as shown in Figure 2, it is a kind of linear Elema, different from embodiment mono-is, its barred body is solid barred body, comprise and be arranged on the cold junction 22 at length direction two ends and the heating section 21 between two cold junctions 22, the barred body of heating section 21 has the banded outer surface 23 extending in the shape of a spiral along barred body length direction, between the adjacent two circle spirals of banded outer surface 23, have helical groove 24, this helical groove 24 forms the interval of setting size between two adjacent circle spirals of banded outer surface 23.
After the cold junction 22 of linear Elema powers up, electric current passes through with spiral shape structure in solid barred body, and heating section 21 produces heats, and inner heat can be dispersed into rapidly outside by groove sidewall and the bottom land wall of helical groove 24, has improved radiating efficiency.
In other embodiments, the spiral of described banded outer surface can be also double helix, or triple helical etc.In addition, when the barred body of heating section is tubulose barred body, also can between two adjacent circle spirals of banded outer surface, helical groove be set, now the bottom land of groove is arranged on tube wall.
