Abstract
The utility model discloses an energy-saving heat transmission pipe. The inner wall of metal pipe is provided with a plurality of tilted inner wings which are arranged spirally in the inner wall of the metal pipe, each inner wing has a height of 0.5-5mm, a width of 0.1-5mm and a thickness of 0.05-1mm. By such spirally-arranged inner wings inside the pipe, the fluid medium via the heat transmission pipe will form the swirling flow under the role of the tilted inner wings so as to further increase the heat exchange coefficient and realize the reinforced heat transmission.
Description
Technical field
The utility model relates to a kind of heat-transfer pipe, particularly a kind of energy-conservation heat-transfer pipe that is provided with inner fin.
Background technology
In the heat transfer technology field, be to improve the coefficient of heat transfer of heat-transfer pipe, normally adopt to change smooth tube wall into rough tube wall, wherein with effect that fin is set on tube wall for well.At present, at the pore inwall inner fin being set generally is to take vertically arrangement or transversely arranged of inner fin is made the mobile generation disorder of fluid media (medium), improves the fluctuation of hot-fluid medium in diabatic process.Yet because that the inner fin of pore inwall is taked is vertical or transversely arranged, though can make the mobile generation of hot-fluid medium necessarily disorderly, its stratosphere is still bigger, influences the intraductal heat exchange coefficient.How further to improve the coefficient of heat transfer of heat-transfer pipe, realize energy savings, in energy-intensive society present situation, have great importance by augmentation of heat transfer.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation heat-transfer pipe, and it can further improve the coefficient of heat transfer by some inner fins of arranging in the shape of a spiral of inside pipe wall setting, realizes augmentation of heat transfer.
The purpose of this utility model is achieved in that the inwall at metal tube is provided with the inner fin of some perks, the inner fin of described some perks the inwall of metal tube in the shape of a spiral shape arrange the every high 0.5～5mm of inner fin, wide 0.1～5mm, thick 0.05～1mm.
Owing to adopted such scheme, at the inwall of metal tube the inner fin of some perks that shape in the shape of a spiral arranges is set, the every high 0.5～5mm of inner fin, wide 0.1～5mm, thick 0.05～1mm, described inner fin is 0～5mm in the sheet spacing of pipe cross section.Fluid media (medium) is by in the heat-transfer pipe time, influenced by the inner fin of these perks, the flow direction of fluid media (medium) changes, medium molecule produces irregular movement, make through the fluid media (medium) in the heat-transfer pipe and under the effect of the inner fin of some perks that shape is in the shape of a spiral arranged, form rotating vortex, the mode of rotational flow is moved in the shape of a spiral, reduce stratosphere, improve the coefficient of heat transfer, its coefficient of heat transfer is 5～8 times of light pipe, 2～3 times of taking vertical or transversely arranged heat-transfer pipe for existing inner fin.Can reduce the consumption of the energy thus effectively, realize energy-conservation.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a cross-sectional schematic of the present utility model;
Fig. 2 is a schematic cross-section of the present utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, it is the inner fin 2 of integrally-built perk that this energy-conservation heat-transfer pipe is provided with some and tube wall at the inwall of the smooth metal tube 1 of outer wall, the inner fin 2 of described some perks is in the inwall shape arrangement in the shape of a spiral of metal tube 1, and its lead angle is 2～45 degree.The every high 0.5～5mm of inner fin, wide 0.1～5mm, thick 0.05～1mm.Described inner fin is 0～5mm in the sheet spacing of pipe cross section.
Perhaps, the metal tube outer wall that is provided with the inner fin of the perk that some shapes in the shape of a spiral arrange by said structure at inwall also is provided with the outer fin of some perks, can play equally and improve coefficient of heat transfer effect.
