Existing finned electric heating tube is conventionally outside housingSurface is wound around a circle stainless strip, forms the fin of holding up, and increases the area of dissipation of electric heating tube, to carryThermal efficiency when high electric heating tube work. At present, owing to being subject to radiating fin technique for coiling on electric heating tubeRestriction, the width of radiating fin generally all can not exceed 10 millimeters, thereby has limited electric heating tube thermal diffusivityThe further raising of energy.
Chinese patent CN201294646 discloses name, and to be called the utility model of " high-efficiency radiating electric heating tube " specialProfit, its patent No. is ZL200820215853.7. The disclosed electric heating tube of this patent comprises Can and peaceBe contained in heating wire and heat-conductive insulation filling in shell, on shell outer surface, spiral is wound with banded heat radiationFin, the section expansion shape linearly shape of radiating fin on its length direction. Coiling on shell surfaceRectilinear radiating fin, the gas channel that shell surface is formed is more unobstructed, can improve air-flow and pass throughSpeed, and then improve radiating efficiency. Above-mentioned electric heating tube mainly adopts linear radiating fin, radiating finWhen sheet carries out coiling on circular electric heating tube housing, the restriction that its fin width is subject to further increases, looseThermal effect is not ideal enough. On the other hand, the internal stress after radiating fin spiral winding is larger, more difficult welding,Use and easily occur the solder joint phenomenon that gets loose after a period of time, cause the service life of whole electric heating tube shorter.
