Abstract
The utility model provides an appurtenance for welding fin, relate to the finned tube make in the design technical field of used instrument. The utility model discloses a set up respectively in the flat board of finned tube both sides, set up the support respectively on every flat board, difference threaded connection screw rod sets up the rocking handle respectively every screw rod one end on every support, the one end of keeping away from the rocking handle at every screw rod sets up the kicking block respectively, and the fin that is used for on the tight finned tube in the top welding of being convenient for is arranged respectively in opposite directions to every kicking block. The utility model discloses when using, through adjusting screw, push up fin and parent tube tightly, make the welding rate can reach 100% to increase heat radiating area, improve the radiating effect.
Description
Technical field
This utility model relates to the design field of used tool during finned tube manufactures.
Background technology
Finned tube, is to improve heat exchange efficiency, generally on the surface of heat exchanger tube by with fin, increasing the external surface area (or internal surface area) of heat exchanger tube, thus reaching to improve the purpose of heat exchange efficiency. The fin of tradition finned tube cannot accomplish welding completely of fin and base tube when welding, thus dispel the heat, heat exchange efficiency does not reach the highest.
Utility model content
This utility model purpose is in that for problem above, it is provided that a kind of aid for welding fin improving welding rate.
This utility model includes the flat board being respectively arranged at finned tube both sides, is respectively provided with support on every piece of flat board, the threaded screw rod of difference on each described support, and the screw rod one end every described is respectively provided with rocking handle; Screw rod every described is respectively provided with jacking block away from one end of rocking handle, and each described jacking block is arranged in opposite directions respectively and is easy to weld for holding out against the fin on finned tube.
Fin and base tube in use, by adjusting screw rod, are held out against, make welding rate can reach 100% by this utility model, thus increasing area of dissipation, improve radiating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model includes the flat board 2 being respectively arranged at finned tube 1 both sides, being respectively provided with support 3 on every piece of flat board 2, on each support 3, the threaded screw rod 4 of difference, is respectively provided with rocking handle 5 in every screw rod 4 one end; Being respectively provided with jacking block 6 at every screw rod 4 away from one end of rocking handle 5, each jacking block 6 is arranged in opposite directions respectively and is easy to welding for the fin 1-1 held out against on finned tube 1.
Claims (1)
1. the aid being used for welding fin, it is characterized in that: include being respectively arranged at the flat board of finned tube both sides, every piece of flat board is respectively provided with support, the threaded screw rod of difference on each described support, the screw rod one end every described is respectively provided with rocking handle; Screw rod every described is respectively provided with jacking block away from one end of rocking handle, and each described jacking block is arranged in opposite directions respectively and is easy to weld for holding out against the fin on finned tube.
