Abstract
The utility model discloses a heat radiating fin comprising a main heat radiating fin body and a stopper, wherein the main heat radiating fin body is provided with a connecting hole, and the external diameter of the main heat radiating fin body is same as that of the stopper. The cross section of the main heat radiating fin body is elliptic or square. The stopper and the heat radiating fin are welded and fixed through flash welding, the external diameter of the stopper is same as that of the heat radiating fin, and weld joints caused by the flash welding are uniform and small and are easy to polish, therefore, the heat radiating fin is not easy to leak water when being used.
Description
Technical field
The utility model relates to a kind of radiator, is specifically related to a kind of fin.
Background technology
Mostly existing heating is to adopt hot water as the heating medium; In cyclic process, need use fin, existing fin comprises heat sink body and block head, and heat sink body is provided with connecting hole; The external diameter of block head is identical with the internal diameter of heat sink body; During use, block head is inserted among the heat sink body, afterwards both are adopted brazing or CO
2Weldering welds together, and its weld seam is inhomogeneous, and in order to make smooth welded seam, smooth, it is flat to need elder generation with milling machine weld seam tentatively to be milled, and uses artificial that weld grinding is smooth, smooth again.Make some commissure become extremely thin during polishing welding seams, leak easily after long-time the use.
The utility model content
The technical problem that the utility model will solve is that existing fin is prone to leak, and a kind of fin of antileaking is provided.
The technical scheme of the utility model realizes in the following manner: a kind of fin, comprise heat sink body and block head, and heat sink body is provided with connecting hole, and the external diameter of said heat sink body is identical with the external diameter of block head.
The cross section of said heat sink body is oval or square.
Said block head flash welding is on heat sink body.
The utility model adopts the flash welding welding fixing block head and fin, because the external diameter of the external diameter of block head and fin is identical, and the even weld of flash welding, weld seam is little, polishes easily, so antileaking when the utility model uses for a long time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
The specific embodiment
As depicted in figs. 1 and 2; The utility model comprises heat sink body 2 and block head 1, and heat sink body 2 is provided with connecting hole 3, and the external diameter of said heat sink body 2 is identical with the external diameter of block head 1; The internal diameter of the internal diameter of heat sink body 2 and block head 1 is complementary, and can not leak after the two is fixing.The cross section of said heat sink body 2 is oval, and the cross section of the cross section of block head 1 and heat sink body 2 is complementary.
In addition, according to the requirement of attractive in appearance or each side, the cross section of said heat sink body 2 can be square or other different shapes.
Said block head 1 is welded on the heat sink body 2 through flash welder.
Flash welding be electric current pass through two the butt joint workpiece contact surface the time; The resistance of the contact point that it the is tiny extremely electric arc of contact surface produces heat; Butting surface is heated; After in due course, butt joint is exerted pressure, and the whole zone that makes two butting surfaces is the electric resistance welding method that gets up of strong bonded simultaneously.
In the utility model, through the connection of flash welding, the weld seam between block head 1 and the heat sink body 2 is little, be prone to polish flat, and even weld.
