Description
Technical field
The utility model belongs to field, particularly a kind of electrothermal tube with dual fail-safe.
Background technology
Electrothermal tube has another name called heat-generating pipe, heating tube, formal name used at school tubular electric heating element, it is the heating wire resistance wire putting into spiral shape in metal tube, and around it and gap insert the insulating powder of good heat resistance, thermal conductivity and insulating properties, heating wire both ends have eduction rod or lead-out wire picks out.Electrothermal tube is special is the electric elements of heat energy by electric energy conversion, due to its low price, easy to use, easy for installation, pollution-free, is widely used in various heating occasion.Electrothermal tube, because of real more use advantage, is also applied to water heater to heat up water.More and local more frequently in some hot water use amounts, requiring that water heater is heated up water can be rapidly and efficiently.For this reason, by the power ascension of electrothermal tube, the object of rapidly and efficiently heating up water can be reached.But so, because electrothermal tube power is higher, the temperature of electrothermal tube itself is too high, is easy to burn out electrothermal tube, and water heater can be made to there is electricity consumption hidden danger, can not take into account heat up water efficiency and security performance well simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of electrothermal tube with dual fail-safe, and it can take into account heat up water efficiency and security performance well.
To achieve these goals, the technical solution adopted in the utility model is as follows: the electrothermal tube of band dual fail-safe, comprise body, and lay respectively at two power connecting columns at body two ends, it is characterized in that, be electrically connected respectively by fuse between described body two ends and described two power connecting columns, described body comprises at least three straightways side by side and connects the arc section of described straightway.
Preferably, described body comprises four straightways side by side, and connects three arc sections of described direct section.
Preferably, the diameter of described body is 8-9 millimeter.
Preferably, the radius of described arc section is 20 millimeters.
Preferably, in described four straightways, two length of straigh line being positioned at two avris are equal, are positioned at two middle length of straigh line equal; And described in be positioned at two avris length of straigh line be positioned at middle length of straigh line 1.5-2 doubly.
Preferably, laser welding method is adopted to be sealed to integrative-structure between described body and described power connecting column.
Electrothermal tube of the present utility model, body adopts multi-segment structure to combine, effectively can improve the efficiency of heating surface, make the contact area of heating tube and water larger, form heat transmission fast, greatly can shorten the time of heating up water, meet hot water use amount greatly and frequently demand, the equal installation insurance silk at electrothermal tube two ends, effectively can improve Electrical Safety simultaneously.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.
As shown in Figure 1, the utility model is a kind of electrothermal tube with dual fail-safe, comprise body 10, and lay respectively at two power connecting columns 20 at body 10 two ends, be electrically connected respectively by fuse 30 between described body 10 two ends and described two power connecting columns 20, described body 10 comprises at least three straightways 11 side by side and connects the arc section 12 of described straightway 11.Electrothermal tube of the present utility model, body 10 adopts multi-segment structure to combine, effectively can improve the efficiency of heating surface, make the contact area of heating tube and water larger, form heat transmission fast, greatly can shorten the time of heating up water, meet hot water use amount greatly and frequently demand, the equal installation insurance silk 30 at electrothermal tube two ends, effectively can improve Electrical Safety simultaneously.
Preferably, described body 10 comprises four straightways 11 side by side, and connect three arc sections 12 of described direct section, body 10 is by four straightways 11 and three arc sections 12 are end to end successively connects and composes, the contact area of the power of heating tube and heating tube and water can be made further to get a promotion, form heat transmission fast, greatly can shorten the time of heating up water.
In addition, in order to make the structure of electrothermal tube more reasonable, effective raising efficiency of heating surface and fail safe, preferably, the diameter of described body 10 is 8-9 millimeter, or the radius of described arc section 12 is 20 millimeters, or in described four straightways 11, two straightway 11 length being positioned at two avris are equal, are positioned at two middle straightway 11 length equal; And described in be positioned at two avris straightway 11 length be positioned at middle straightway 11 length 1.5-2 doubly, all can improve the power of heating tube to a certain extent, accelerate to heat up water efficiency.
In addition, between described body 10 and described power connecting column 20, adopt laser welding method to be sealed to integrative-structure, the sealing property of body 10 end is greatly promoted, the Electrical Safety performance of electrothermal tube can be strengthened.
