Abstract
The utility model discloses a high efficiency energy-saving heat dissipating steel pipe with an oval external surface and internal groove ribs, which comprises an oval pipe body. The oval internal surface of the oval pipe body is provided with a plurality of axial grooves. A plurality of axial grooves are arranged continuously and the groove edges of the adjacent axial grooves are connected in turn or the plurality of axial grooves are arranged at intervals and the groove edges of the adjacent axial grooves have a certain space. The section of the axial grooves is in a circular arc shape, an oval arc shape or a parabola arc shape. The utility model has novel and specific design and the internal wall surface of the oval steel pipe thereof is not flat arc shape but groove shape, which ensures that the utility model has the mechanism performance of the conventional cold-drawing seamless steel pipe, increases the area of an internal cavity thereof and creates predominant prerequisite for the increase of the passing quantity of flow medium and quick heat conduction. The utility model has good economic benefit after being popularized.
Description
One. technical field: the utility model relates to a kind of radiating tube, particularly relates to a kind of outer oval inside groove rib novel high-efficiency and energy-saving heat radiation steel pipe.
Two. background technology: at present, various heat exchanger and radiator are all used in Coal Chemical Industry industry, refrigeration industry device fabrication, and the various transformer of power system also uses radiator, the runner pipe of radiator is a radiating tube, and traditional radiating tube all is circular or oval solid drawn tube, the surface area of its inner surface is limited, and heat-transfer effect is limited.
Three. the content of utility model:
Technical problem to be solved in the utility model is: overcome the defective of prior art, a kind of uniqueness novel in design, high, the long-pending big outer oval inside groove rib novel high-efficiency and energy-saving heat radiation steel pipe of section cavity surface of intensity are provided.
The technical solution of the utility model is: a kind of outer oval inside groove rib novel high-efficiency and energy-saving heat radiation steel pipe, contain oval body, and the elliptical inner surface of described oval body is provided with a plurality of axial notches.
A plurality of described axial notches are provided with continuously, and the trough rim of adjacent axial notch links to each other successively.Perhaps a plurality of described axial notches are provided with at interval, and the trough rim of adjacent axial notch has certain spacing.
The cross section of described axial notch is a circular arc, and the radius of curvature of the cross section of adjacent axial notch is identical or inequality.
Perhaps, the cross section of described axial notch is an ellipse arc, and the radius of curvature of the cross section of adjacent axial notch is identical or inequality.
Perhaps, the cross section of described axial notch is a parabolic arc, and the radius of curvature of the cross section of adjacent axial notch is identical or inequality.
Perhaps, the cross section of described axial notch is approximately triangle, rectangle, square or trapezoidal.
The beneficial effects of the utility model are:
1. the utility model is novel in design unique, and the non-arc of its oval steel pipe inner wall surface is flat-shaped, but is the groove shape, has greatly changed the shape of oval steel pipe internal-surface, has increased table cavity area in it.
2. the utility model muscle rib place is different with the groove wall thickness, because the wall thickness effect of muscle rib place can guarantee to have the mechanical performance (that is: stiffness and intensity etc.) of conventional solid drawn tube; Again because groove and groove V-type or place, U type bottom wall thickness are thinner, make it that the section cavity surface is long-pending can to increase 25～40%, for the flow media increment by having created superior prerequisite basic condition with the Rapid Thermal conduction.
3, the utility model requires and needs according to technical data, changes design and produces the interior high-precision seamless steel pipe of oval many grooves inside groove rib cold-drawn of ￠ 25～76X14～51 scopes, and specification is many, and is easy to use.
4, the axial notch of the utility model inner surface can be provided with continuously, and its edge connects successively, can also be provided with at interval, its edge at intervals, to adapt to the demand of different occasions.
5, the utility model is applied widely, the various heat exchanger and the radiator of Coal Chemical Industry industry, refrigeration industry device fabrication both be widely used in, be applicable to various transformer again, particularly be applicable to ehv power transmission line transformer radiating tube, be easy to promotion and implementation, have good economic benefit.
Four. description of drawings:
Fig. 1 is one of structural representation of outer oval inside groove rib novel high-efficiency and energy-saving heat radiation steel pipe;
Fig. 2 be outer oval inside groove rib novel high-efficiency and energy-saving heat radiation steel pipe structural representation two.
Five. the specific embodiment:
Embodiment one: referring to Fig. 1, among the figure, the elliptical inner surface of the oval body 1 of outer oval inside groove rib novel high-efficiency and energy-saving heat radiation steel pipe is provided with a plurality of axial notches 2.A plurality of axial notches 2 are provided with continuously, and the trough rim of adjacent axial notch links to each other successively.
The cross section of axial notch 2 is a circular arc, also can be ellipse arc, can also be parabolic arc, can also be the shape (such as trapezoidal, rectangle, square etc.) of other shape certainly, determines as required.And the radius of curvature of the cross section of adjacent axial notch 2 can be identical, also can be inequality, can also identical and inequality being crisscross arranged, and decide as required.
The muscle rib place of axial notch 2 is different with the bottom wall thickness, because the wall thickness effect of muscle rib place can guarantee to have the mechanical performance (that is: stiffness and intensity etc.) of conventional solid drawn tube; Again because groove and groove V-type or place, U type bottom wall thickness are thinner, make it that the section cavity surface is long-pending can to increase 25～40%, for the flow media increment by having created superior prerequisite basic condition with the Rapid Thermal conduction.
Embodiment two: present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: a plurality of axial notches 2 are provided with at interval, and the trough rim of adjacent axial notch 2 has certain spacing, and the cross section of axial groove 2 is approximately square among the figure.
The radius of curvature that changes the shape of axial notch, the arrangement mode that changes axial notch and change axial notch can be formed a plurality of embodiment, is common variation of the present utility model, does not describe in detail one by one at this.
