Abstract
PURPOSE: To prevent dropwise falling of liquid drops produced on the outer surface of a copper tube along a metal filament and prevent formation of a liquid membrane on the surface of the copper tube to prevent the lowering of the heat transfer efficiency, by arranging the metal filament around the periphery of the copper tube so that the metal filament is arranges to repeat attachment and separation to and from the copper tube to surround the copper tube.
CONSTITUTION: The metal filament 2 curved orderly and continuously in a sign curve shape within a plane, is applied to the copper tube so that the metal filament 2 repeats attachment and separation to and from the copper tube 1 as viewed along the centerline thereof, and the metal filament 2 spirally surrounds the copper tube 1 in a constant pitch, and the metal filament 2 is fixed to the copper pipe 1 at the contact portion 3 between the copper pipe 1 and metal filament 2. The fixing of the copper pipe to the metal filament may be performed by a method of dipping them in a molten metal bath or that of caulking, in addition to the resistance welding.
