Abstract
The invention discloses a heat exchange tube with fins embedded inside. The heat exchange tube is composed of a tube body and an inner tube which are sleeved. The tube body is a round tube, and the inner tube is composed of longitudinal fins arranged evenly and forming a polygonal tube. 3-16 fins are arranged on the cross section of the inner tube and unfolded radially, and the inner tube is in contact with an inner wall of the tube body through fin outlines in a matched mode. The built-in longitudinal fins in the tube body are arranged towards the heat exchange medium flowing direction, no flowing resistance exists, a heat exchange medium flows smoothly, the heat exchange area of the tube body is increased by adding the inner tube, and the heat exchange efficiency is improved. The tube body is supported by the embedded inner tube, the integral strength is good, anti-deforming capacity is good, installing is convenient, and the heat exchange tube is especially suitable to be matched with tube type heat changers of various specifications.
Description
Technical field
The present invention relates to a kind of heat exchanger tube, specifically, the present invention relates to a kind of embedded rib heat exchanging pipe.
Background technology
Heat exchanger tube is the critical component in the pipe heat exchanger, and its structure directly affects heat exchange efficiency.The built-in heat exchanger tube of pipe heat exchanger adopts smooth wall pipe usually, and in order further to increase heat exchange efficiency, the routine techniques measure that the industry is taked is that this structure can realize expecting purpose at smooth wall pipe string cover fin.But the heat exchanger tube of string cover fin is also Shortcomings in actual applications, mainly is that fin is radial development, volume is large, and flowing to of fin plate face and heat transferring medium is perpendicular, is detained heat transferring medium between the fin, this problem has also been lost certain heat exchange efficiency except increasing the liquid resistance.In addition, fin is sheet member, and the fin rigidity that is radial development is relatively poor, and mounting process is complicated, and production efficiency is low.
Summary of the invention
The present invention overlaps the deficiency of fin heat exchange pipe mainly for the prior art guest performer, propose a kind of embedded rib heat exchanging pipe of remarkable increase heat exchange area, and this tubular construction is simple, radial dimension is little, and non-deformability is strong, the aneroid resistance.
The present invention is achieved through the following technical solutions technical goal.
Embedded rib heat exchanging pipe, it is comprised of body and inner tube, and described body is pipe.Its improvements are: described inner tube forms the polygon pipe by uniform longitudinal fin, and fin is radial development on cross section, and inner tube contacts cooperation with the fin outline with inboard wall of tube body.
In the said structure, uniform 3～16 longitudinal fins of inner tube.
As further improvement project, the flared fin lateral cross section in inner tube footpath is fan-shaped.
As further improvement project, the flared fin lateral cross section in inner tube footpath is semicircle.
As further improvement project, the flared fin lateral cross section in inner tube footpath is triangle.
The present invention compared with prior art has following good effect:
1, embedded fin structure is simple, and same size condition lower tube body radial dimension is little;
2, the inner tube that is provided with longitudinal fin is built in the body, and longitudinal fin flows to along heat transferring medium, does not have flow resistance, and heat transferring medium is unblocked, and heat exchange efficiency is high;
3, body is supported by embedded inner tube, good integral strength, and non-deformability is strong;
4, tube wall is the light wall, is conducive to the installation and maintenance operation.
Description of drawings
Fig. 1 is structural upright schematic diagram of the present invention.
Fig. 2 is Fig. 1 end view, and embedded inner tube fin is fan-shaped among the figure.
Fig. 3 is Fig. 1 end view, and embedded inner tube fin is semicircle among the figure.
Fig. 4 is Fig. 1 end view, and embedded inner tube fin is triangle among the figure.
The specific embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Embodiment 1
Embedded fin heat exchange pipe shown in Figure 1, it is comprised of body 1 and inner tube 2.Described body 1 is common pipe, and inner tube 2 forms the polygon pipe by uniform longitudinal fin, and the fin on inner tube 2 cross sections is radial development, and inner tube 2 contacts cooperation with the fin outline with body 1 inwall.The present embodiment middle tube body 1 internal diameter 18mm, inner tube 2 outside diameters are similarly 18mm.Because body 1 bore is less, inner tube 2 external 3 longitudinal fins reliably contact, locate with body 1 inwall in order to make inner tube 2, the longitudinal fin lateral cross section semicircle as shown in Figure 3 of inner tube 2 in the present embodiment.The inner tube 2 of body 1 interior plug dress is cooperated by 6 longitudinal fin contacts, forms overall structure, significantly increases the intensity of body 1, improves non-deformability.Because of the external longitudinal fin of inner tube 2 along the heat transferring medium direction that flows, heat exchanging medium flow is out-of-date not to have the liquid resistance.On the other hand, built-in inner tube 2 significantly increases the heat exchange area of body 1, greatly improves heat exchange efficiency.The present embodiment increases approximately 2 times of heat exchange areas, can improve heat exchange efficiency about 15%.It is smooth wall pipe that the present invention keeps body 1 in configuration aspects, and the installation and the user that greatly are convenient in the manufacture process safeguard.
Embodiment 2
The present embodiment middle tube body 1 internal diameter 30mm, built-in inner tube 2 outside diameters are similarly 30mm, because the heat exchanger tube specification is larger, are equipped with 8 longitudinal fins in inner tube 2.See fin triangle as shown in Figure 4 from inner tube 2 cross sections, other structure is identical with embodiment 1, and effect is also similar.
Embodiment 3
The present embodiment middle tube body 1 internal diameter 50mm, built-in inner tube 2 outside diameters are similarly 50mm, because the heat exchanger tube specification is large, are equipped with 16 longitudinal fins at special pipe 2.See as shown in Figure 2 fan-shaped of fin from special pipe 2 cross sections, other structure is identical with embodiment 1, and effect is also similar.
The inner tube that the present invention is embedded with longitudinal fin in body 1 is core protection content of the present invention, and any technical scheme of doing distortion or combination according to the principle of the invention all drops in the present patent application protection domain.
