Description
Technical field
The utility model relates to a kind of electrothermal component, especially relates to a kind of pair of voltage dual-power electrothermal tube structure.
Background technology
Electrothermal tube is a kind of for adding the tubular electrothermal element of hot-air, metal die and various liquid.In electrothermal tube, be filled with oxide, available machine for shrinking, by caliber shrinking, makes medium of oxides closely knit, guarantees that heating wire and air are isolated, and center skew does not occur and brushes up against tube wall.Unit are caloric value just can increase by tens times like this, and also can be increased to accordingly more than 10 years useful life.Compare with the electric heating element of identical large heat, tubulose electrothermal tube can be saved 5% thermo electric material, and the heat efficiency can reach more than 90%.
In the tube chamber of common electrothermal tube, only have a heating wire, the efficiency of heating surface is lower.As publication number is: a kind of temperature measurement electric heat tube that the Chinese invention patent of CN101018433A provides, can know PTC electrothermal tube heating temp, by PTC heating wire, magnesium oxide insulated layer, outer tube etc., formed.This electrothermal tube only has a heating wire, function singleness, and the efficiency of heating surface is lower.
Utility model content
The utility model is mainly for the low problem of the existing efficiency of heating surface of existing electrothermal tube, and a kind of simple in structure, two voltage dual-power electrothermal tube structures that the efficiency of heating surface is high are provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of pair of voltage dual-power electrothermal tube structure, comprise metal outer pipe, in the tube chamber of metal outer pipe, there is magnesia powder, it also comprises two heating wire being located in metal outer pipe, the two ends of metal outer pipe are respectively connected with two stems, the two ends of one of them heating wire are wrapped on the one group of stem in left and right and form loop, and the two ends of another heating wire are wrapped on another group stem of left and right and form loop.Adopt single tube mariages to reach the requirement of the two power of single heating tube, two heating wire all can work independently.Two heating wire can adopt high-low-position to arrange, make it have leveled heating effect, the efficiency of heating surface is higher.Two heating wire are the same power of same voltage, also can be different voltage different capacities.
As preferably, the two ends of described metal outer pipe are equipped with ceramic plug, and a part for ceramic plug is embedded in metal outer pipe, and stem runs through ceramic plug and is connected with heating wire.The two ends of metal outer pipe are equipped with ceramic plug, and pottery has good insulating properties, are easy to again and metal appearance tight seal.
As preferably, the mouth of pipe of described metal outer pipe is filled with silica gel.The mouth of pipe of metal outer pipe is filled with silica gel, further increases the sealing of the mouth of pipe.
As preferably, two described heating wire Yan Guannei centers are arranged in parallel.Two heating wire Yan Guannei centers are arranged in parallel, and are convenient to leveled heating.
As preferably, two described heating wire are arranged to screw winding along central shaft in pipe.Two heating wire are arranged to screw winding along central shaft in pipe, heat more even.
Therefore, the beneficial effects of the utility model are: adopt single tube mariages to reach the requirement of the two power of single heating tube, two heating wire all can work independently, and two heating wire can adopt high-low-position to arrange, make it have leveled heating effect, the efficiency of heating surface is higher.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Shown in figure: 1-metal outer pipe, 2-magnesia powder, 3-heating wire, 4-stem, 5-ceramic plug.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure of description 1, a kind of pair of voltage dual-power electrothermal tube structure, comprise metal outer pipe 1, in the tube chamber of metal outer pipe, there is magnesia powder 2, it also comprises two heating wire 3 being located in metal outer pipe, the two ends of metal outer pipe are equipped with ceramic plug 5, a part for ceramic plug is embedded in metal outer pipe, the mouth of pipe of metal outer pipe is filled with silica gel, stem runs through ceramic plug and is connected with heating wire, the two ends of metal outer pipe are respectively connected with two stems 4, two heating wire Yan Guannei centers are arranged in parallel, the two ends of one of them heating wire are wrapped on the one group of stem in left and right and form loop, the two ends of another heating wire are wrapped on another group stem of left and right and form loop,
This electrothermal tube adopts assembles the heating wire of two kinds of different voltages and power in a tubing, two kinds of heating wire parallel arrangement are in metal outer pipe, and connected by stem, adopt single tube mariages to reach the requirement of the two power of single heating tube, two heating wire all can work independently.Two heating wire can adopt high-low-position to arrange, make it have leveled heating effect, the efficiency of heating surface is higher.Reasonable in design, the efficiency of heating surface is high, can bend to required different structure shape, and the heating appliances of adapted different model volume, is applicable to country variant flexibly, meets the product of different voltages.Two heating wire are the same power of same voltage, also can be different voltage different capacities.
