A kind of novel pair of heat-generating pipe
Technical field
The utility model relates to a kind of electro-heat equipment, particularly a kind of novel pair of heat-generating pipe.
Background technology
In the manufacturing of electric coffee pot, use sometimes a kind of structure of electro-heat equipment, realize the structure of heating part by the welding of " C " type heat-generating pipe and prototype stainless steel disc, obvious this structure efficiency is not high, and heating is slow, and useful life is not long.
Summary of the invention
In order to overcome the defective of prior art, the utility model provides following technical scheme:
A kind of novel pair of heat-generating pipe, comprise internal heat generation pipe, outer heat-generating pipe, aluminium sheet and stainless steel disc, internal heat generation pipe and outer heat-generating pipe are " C " type, riveted joint has cylindrical double-screw bolt on the described aluminium sheet, described aluminium sheet one side is welded with stainless steel disc, another side and Inner, the welding of outer heat-generating pipe, described internal heat generation pipe and outer heat-generating pipe are welded in the edge of the top of aluminium sheet from inside to outside.
Further, wherein a part of unsettled on stainless steel disc after the welding of described outer heat-generating pipe and aluminium sheet.
Further, described aluminium sheet center is provided with location hole, determines relative position by spacer and stainless steel disc.
The beneficial effect that the utility model brings is: two-tube heating is fast, can be incubated long service life.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
As shown in Figure 1 to Figure 3, a kind of novel pair of heat-generating pipe, comprise internal heat generation pipe 1, outer heat-generating pipe 2, aluminium sheet 4 and stainless steel disc 3, internal heat generation pipe 1 and outer heat-generating pipe 2 are " C " type, riveted joint has cylindrical double-screw bolt 41 on the described aluminium sheet 4, described aluminium sheet 4 one sides and stainless steel disc 3 welding, another side and Inner heat-generating pipe 1 and 2 welding of outer heat-generating pipe, described internal heat generation pipe 1 and outer heat-generating pipe 2 are welded in the edge of the top of aluminium sheet 4 from inside to outside.Described outer heat-generating pipe 2 is wherein a part of unsettled on stainless steel disc 3 after welding with aluminium sheet 4.Described aluminium sheet 4 centers are provided with location hole 42, determine relative position by spacer 5 and stainless steel disc 3.
The described structure heating efficient of the present embodiment is high, can be incubated long service life.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
