Abstract
The utility model discloses an electric heating pipe with heat radiating fins for electric water heaters. A metal sleeve pipe of the electric heating pipe is provided with the heat radiating fins of a circular sheet type or a spiral plate sheet type, or the metal sleeve pipe of the electric heating pipe is provided with an outer sleeve pipe which is provided with the heat radiating fins. As the heat transfer area of the metal sleeve pipe is increased, the heat transfer effect is improved. The utility model can overcome the phenomenon of the electric heating pipe of the existing electric water heater that as the heat transfer effect is poor and the local is overheat, the sleeve pipe burst, and the electric heating wire is burnt out. Thus, the utility model improves use safety of the electric heating pipe, and extends service life.
Description
The utility model relates to a kind of electrothermal tube that electric heater has fin that is used for.It belongs to the improvement of electrothermal tube.
At present, the electrothermal tube that uses on the electric heater, its metal sleeve generally is the smooth wall pipe that employing waits wall thickness, the electrothermal tube of this smooth wall pipe, heat-transfer effect is not good enough because heat transfer area is little, the phenomenon of blowing of cover pipe explosion and heating wire easily taking place, cause electrothermal tube shorter useful life, has reduced fail safe.
For overcoming the above-mentioned weak point of electrothermal tube in the existing electric heater, the purpose of this utility model is to provide a kind of flange-cooled electrothermal tube of electric heater that is used for, and this electrothermal tube has the advantages that heat-transfer effect is good, safe in utilization, the life-span is long.
For achieving the above object, the utility model is realized by following proposal.The flange-cooled electrothermal tube of the electric heater that insulating material constituted by heating wire in terminal pad, metal sleeve, the sleeve pipe and filling.It is characterized in that: on the cylindrical of metal sleeve, be shaped on fin.
Be shaped on fin on the above-mentioned metal sleeve cylindrical, be included in the metal sleeve overcoat and be shaped on the outer tube that has fin.
Above-mentioned fin is the disk shape, or comprises the spiral plate sheet that single head is above.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation of split-type structural.
Fig. 2 is the utility model structural representation of integral structure.
1 is terminal pad among the figure, and 2 is metal sleeve, and 3 is fin, and 4 is heating wire, and 5 is binding post.
By accompanying drawing as can be known, the utility model is with the significant difference of electrothermal tube that existing electric heater uses, is shaped on fin on its metal sleeve.Its fin shape is made the disk shape, perhaps makes single head, double end, three spiral plate sheet.For the fin of disk shape, distance between commutator segments preferably equates, but each fin opening distinguish also.The above-mentioned disk shape or the fin of spiral plate sheet all can adopt welding method or casting method directly on metal sleeve, are perhaps making the outer tube that has above-mentioned fin on the metal sleeve.So manufacture method has not only improved the metal sleeve heat transfer area, also has the effect that increases metal jacket pipe intensity simultaneously.
The utility model is compared with the electrothermal tube on the existing electric heater, because it is shaped with fin at metal sleeve, has increased Heat transfer area not only can improve heat-transfer effect greatly, effectively avoids again the cover pipe explosion and the electricity that cause because of hot-spot simultaneously Heated filament blows, so can greatly improve safety in utilization again, increases the service life.
Claims (3)
1. one kind is used for the electrothermal tube that electric heater has fin, and it is that insulating material by heating wire in terminal pad, metal sleeve, the metal sleeve and filling is constituted, and it is characterized in that: the outer round surface at metal sleeve is shaped on fin.
2. be used for the electrothermal tube that electric heater has fin by claim 1 is said, it is characterized in that: be shaped on fin on the said sleeve pipe, be included in and be shaped on the outer tube that has fin on the metal sleeve.
