Abstract
The utility model provides an interior foreign minister's wing needle recuperator heat exchange tube, include: a plurality of fins (2) of body (1) and body outer wall, its characterized in that, body (1) inner wall be along radially setting up a plurality of inner fins (3), the cross -section of inner fin (3) is the cylindricality. The utility model discloses an interior foreign minister's wing needle recuperator heat exchange tube greatly increased internal and external surface heat transfer area increases intraductal fluidic reynolds number and turbulence scale, is showing and is improving heat exchange coefficient.
Description
Technical field
The utility model relates to technical field of heat exchangers, particularly relates to a kind of interior foreign minister's wing needle recuperator heat exchanger tube.
Background technology
In prior art, application number 201120168646.2, utility model title " a kind of fin heat exchange pipe ", provides the heat exchanger tube that a kind of inboard wall of tube body sets up rack structure, increases the heat exchange area of traditional smooth inboard wall of tube body to a certain extent; But, physical arrangement in pipe is also increased for the rack structure under material same levels pressure piping of the same race and pressure reduction conditions, makes heat exchanging medium flow quantitative change few, very little for the contribution margin increasing the coefficient of heat transfer; Therefore, how to increase the coefficient of heat transfer, increasing the turbulivity of inner surface heat exchange area and increase tube fluid, is problem demanding prompt solution.
Utility model content
The utility model mainly solves and ensures how heat transferring medium in body increases the technical problem of the heat exchange area of inboard wall of tube body under the condition of certain flow, pressure and allowable pressure drop, propose a kind of in foreign minister's wing needle recuperator heat exchanger tube.
In order to achieve the above object, interior foreign minister's wing needle recuperator heat exchanger tube that the utility model provides, comprising: some fins 2 of body 1 and tube wall, is characterized in that, body 1 inwall is disposed radially some inner fins 3, and the cross section of described inner fin 3 is cylindricality.
Preferably, the height of described inner fin 3 and the ratio of body 1 internal diameter are: 1:2 to 30.
Preferably, the height of described inner fin 3 and the ratio of body 1 internal diameter are: 1:4 or 8.
Preferably, the height of described inner fin 3 is consistent.
Preferably, adjacent inner fins 3 is staggered in height.
Preferably, the aspect ratio of adjacent inner fins 3 is: 1:0.1 to 5.
Preferably, the aspect ratio of adjacent inner fins 3 is: 1:2.
Preferably, the root of adjacent inner fins 3 connects with arcuate structure.
Preferably, connector 4 is set at interval of on the fin 2 of 22.5 degree, 30 degree, 45 degree or 90 degree.
Preferably, described connector 4 is spherical or Polygonal column shape.
Beneficial effect: interior foreign minister's wing needle recuperator heat exchanger tube of the present utility model increases surfaces externally and internally heat exchange area greatly, increases Reynolds number and the turbulivity of tube fluid, significantly improves the coefficient of heat transfer 10 to 30%.
