Abstract
W type extended surface tube relates to the design technical field of cooling tube. The utility model discloses an at least foundation pipe, multiunit are arranged the fin on the parent tube outer wall along parent tube length direction and are organized, are equipped with first clearance between adjacent two sets of fins group, every group fin component include do not that a pair of cross -section is the adj. Tabular fin of " W " type, the inboard of every adj. Tabular fin be equipped with respectively with parent tube periphery complex arc recess, whenever pass through arc recess symmetry to adj. Tabular fin and set up in the parent tube both sides, the plane of the every adj. Tabular fin axis of perpendicular to parent tube is respectively arranged, be equipped with the second clearance between every opposite side to adj. Tabular fin. The utility model discloses a cross -section is the fin of " W " type, and this kind of structure because the flue gas flows through when receiving the hot side, presents the flow of " S " shape, and it provides efficient heat transfer characteristic to the washing away of the facial canal that is heated to have strengthened, can make arranged in flue space less relatively by the hot side, reduces manufacturing cost.
Description
Technical field
This utility model relates to the design field of radiating tube.
Background technology
Finned tube, it is to improve heat exchange efficiency, generally on the surface of heat exchanger tube by with fin, increase the external surface area (or internal surface area) of heat exchanger tube, thus reaching to improve the purpose of heat exchange efficiency, W type extended surface tube falls within the one of finned tube, and the heat radiation of W type extended surface tube, the heat exchange efficiency that use in the market are general, how to improve the heat radiation of W type extended surface tube, heat exchange efficiency further, be always up the main direction of studying in industry.
Utility model content
This utility model purpose is in that for problem above, it is provided that a kind of heat radiation, the W type extended surface tube that heat exchange efficiency is high.
This utility model includes at least one foundation pipe, the many groups of fins set being arranged on base tube outer wall along base tube length direction, is provided with the first gap between two adjacent groups fins set; Often organizing described fins set and include the plate-shaped fins that a pair cross-section is " W " type respectively, the inner side of every piece of plate-shaped fins is respectively equipped with the arc groove coordinated with base tube periphery, and every pair of plate-shaped fins is symmetricly set in base tube both sides by arc groove; The plane of every piece of plate-shaped fins is respectively perpendicular to the axis of base tube and arranges; The second gap it is provided with between the opposite side of every pair of plate-shaped fins.
The fin that this utility model adopts cross section to be " W " type, this structure, when flowing through heating surface due to flue gas, present the flow process of serpentine, strengthen washing away heating surface tube, it is provided that efficient heat compensator conducting property, heating surface can be made to be arranged in relatively small flue space, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A of the present utility model to sectional view.
Detailed description of the invention
As shown in Figure 1, 2, this utility model includes a foundation pipe 1, the many groups of fins set 2 being arranged on base tube 1 outer wall along base tube 1 length direction, is provided with the first gap 3 between two adjacent groups fins set 2; Often group fins set 2 includes the plate-shaped fins 2-1 that a pair cross-section is " W " type respectively, the inner side of every piece of plate-shaped fins 2-1 is respectively equipped with the arc groove 2-1-1 coordinated with base tube 1 periphery, and every couple of plate-shaped fins 2-1 is symmetricly set in base tube 1 both sides by arc groove 2-1-1;The plane of every piece of plate-shaped fins 2-1 is respectively perpendicular to the axis of base tube 1 and arranges; The second gap 4 it is provided with between the opposite side of every couple of plate-shaped fins 2-1.
