Abstract
The utility model belongs to the technical field of electric heating. The finned extended surface is adopted to strengthen the heat exchange of an electrothermal tube, enhance the heat exchange effect of the electrothermal tube, increase the heat efficiency of the electrothermal tube, and extend the service life of the electrothermal tube. An electrothermal tube with fins is mainly characterized in that the heat exchange surface of the electrothermal tube is provided with finned extended surface, and the electrothermal tube with fins has broad applications in drying industry, electric furnace industry, plating industry, baking oven industry and heating industry.
Description
Under technical field: the invention belongs to the electric-heating technology field, is a kind of improved electrothermal tube, and its adopts the form of extended surface to strengthen the heat exchange of electrothermal tube, improves the heat efficiency of electrothermal tube, and has prolonged electrothermal tube useful life greatly.
As shown in the figure, existing electrothermal tube mainly is made up of resistance wire (4), steel pipe or copper pipe (2), insulation charges (3), magnetic joint (5), fastening bolt (7), nut (6).The electrothermal tube overwhelming majority who is widely used in fields such as drying, Electric heat oven, heating who sells on the market is this form.Usually electrothermal tube adopts the mode and the surrounding medium of convection current to carry out heat exchange, because the electrothermal tube external surface area is very little, the electrothermal tube surface is very big with the medium temperature difference during use, the electrothermal tube surface temperature is very high, very big in some use occasion thermal radiation loss, both reduced the heat efficiency of electrothermal tube, and made the electrothermal tube surface oxidation cause the electrothermal tube life-span to be reduced easily.
Purpose of the present invention is exactly that a kind of electrothermal tube that has improved will be provided, accompanying drawing is the structure chart of fin electrothermal tube, it is strengthened the form that the light pipe of former electrothermal tube outer surface makes fin into to electrothermal tube, increase the heat exchange effect of electrothermal tube, improves the heat efficiency and increases electrothermal tube useful life.
The part of sequence number in the accompanying drawing (1) is the reinforced portion of fin electrothermal tube, is main contents of the present invention.The fin electrothermal tube is finished as follows: keeping the last one procedure that increases under the constant situation of former electrothermal tube technology, utilize at common electrical heat pipe outer surface steel (copper) Guan Shangzai and roll (around) mode of system composite fin tube roll (around) go out aluminium (steel) fin.
Power is identical, fin electrothermal tube and common electrical heat pipe that length is the same compare test, fin electrothermal tube surface temperature reduces more than 300 ℃, and adopt the heat Electric heat oven to 200 ℃ of equal volume of fin electrothermal tube and common electrical heat pipe respectively, fin electrothermal tube required time is a common electrical heat pipe 4/5, as seen adopts fin electrothermal tube energy-saving effect remarkable.
Claims (1)
- A kind of surface gives the fin electrothermal tube that heat exchange is strengthened, and it is characterized in that the heat release outer surface of electrothermal tube has finned extended surface.
