Abstract
Tooth punching type spiral fin coil relates to the design technical field of used finned tube among the shaft boring machine cooling system. The utility model discloses a parent tube, fin, fin include that connection piece, an organic whole set up a plurality of fin bodies on the connection piece, and every fin body respectively and form the contained angle between the connection piece, the connection piece along the length direction of parent tube spiral closely around put the parent tube periphery and with parent tube welded fastening, every two adjacent fin body staggered arrangements. The utility model discloses because the connection piece welds with the parent tube completely, adjacent fin staggered arrangement, and the tooth root is on earth, and the beneficial effect who compares with prior art is: increase heat radiating area, increased air turbulence, improved the radiating effect.
Description
Technical field
This utility model relates to the design field of finned tube used in drilling equipment cooling system.
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 tooth root of tradition tooth punching type spiral fin coil fin has certain thickness from base tube, and fin bottom, directly around the home in base tube periphery, is welded and fixed by spot welding or ending, and its radiating effect, stability all can not meet the instructions for use of equipment.
Utility model content
This utility model purpose is in that for problem above, it is provided that the tooth punching type spiral fin coil of a kind of good heat dissipation effect.
This utility model includes base tube, fin, and described fin includes connecting sheet, is integrally formed at the multiple fin body connected on sheet, each described fin body respectively with is connected between sheet and forms angle; Described connection sheet is spiral closely around the home in base tube periphery and be welded and fixed with base tube along the length direction of base tube; Every two adjacent fins body interlaced arrangement.
This utility model welds with base tube completely owing to connecting sheet, adjacent fins interlaced arrangement, and tooth root is on earth, and having the beneficial effect that compared with prior art increases area of dissipation, increases air agitation, improves radiating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, this utility model includes base tube 1, fin 2, and described fin 2 includes connecting sheet 2-1, is integrally formed at the multiple fin body 2-2 connected on sheet 2-1, each described fin body 2-2 respectively with is connected between sheet 2-1 and forms angle; Described connection sheet 2-1 is closely welded and fixed in base tube 1 periphery and with base tube 1 around the home along the length direction of base tube 1 is spiral; Every two adjacent fins body 2-2 interlaced arrangement.
