Abstract
The utility model discloses a kind of 3 D deformation with internal-rib to become space heat exchanger tube, including the distortion pipeline section of centre and the circular straighttube section at both ends, the distortion pipeline section is formed by pipe through helically twisted, the distortion pipeline section and the multiple fins of circular straighttube section inner wall even distribution, the fin is uniformly and symmetrically distributed along ips, and is equidistantly uniformly distributed along pipe range direction.The utility model has the advantages that 3 D deformation change space pipe is larger in working medium entrances section bore, it is gradually reduced along pipe range direction bore with the reduction of Temperature of Working, the stable flow velocity in working medium heat transfer process can so be ensured so that the heat transfer coefficient of heat transfer process is basically unchanged, and contributes to augmentation of heat transfer.The utility model improves the efficiency of heat exchange, has the advantages of coefficient of heat transfer is high, less scaling, working medium particularly relatively low for intraductal heat exchange coefficient.
Description
Technical field
It the utility model is related to gas converting heat technical field, and in particular to a kind of 3 D deformation with internal-rib becomes space and changed
Heat pipe.
Background technology
Realize that the gas heat exchanger to be exchanged heat between gas and gas is widely used in the fields such as chemical industry, power, metallurgy, petrochemical industry,
Such as：The cooler of the heat recovery, air of industrial high temperature flue gas as cooling medium etc..But due to the heat conduction system of gas
Number is low, specific heat capacity is small, causes gas very low with the heat transfer coefficient of gas heat exchanging process.
Core parts of the heat exchanger tube as heat exchanger, the quality of its heat transfer property directly influence heat exchanger operational effect,
Conventional optical tube heat exchanger heat transfer effect is poor, and shell-side pressure drop is big, and easy the problem of triggering tube bundle vibration.Which has limited heat exchanger heat exchange
The raising of efficiency, hinder the development of heat exchanger.
Utility model content
The purpose of this utility model is to provide a kind of 3 D deformation with internal-rib and becomes space heat exchanger tube, makes full use of heat exchange
Manage the helically twisted and 3 D deformation of internal-rib and become space geometrical feature, promote augmentation of heat transfer, improve heat exchange efficiency.
The utility model is achieved through the following technical solutions：
A kind of 3 D deformation with internal-rib becomes space heat exchanger tube, including middle distortion pipeline section and the circular straighttube at both ends
Section, the distortion pipeline section are formed by pipe through helically twisted, the distortion pipeline section and the multiple fins of circular straighttube section inner wall even distribution,
The fin is uniformly and symmetrically distributed along ips, and is equidistantly uniformly distributed along pipe range direction.
Further, the distortion pipeline section and circular straighttube section use integrated molding structure.
Further, different sizes can be made as needed for the fin physical dimension and spacing.
Further, the bore that the distortion pipeline section working medium flows into end is more than the bore of working medium outflow end, and interlude is smooth
Transition.
The utility model has the advantages that：3 D deformation change space pipe is larger in working medium entrances section bore, along pipe range direction mouth
Footpath is gradually reduced with the reduction of Temperature of Working, can so ensure the stable flow velocity in working medium heat transfer process so that exchanged heat
The heat transfer coefficient of journey is basically unchanged, and contributes to augmentation of heat transfer.The utility model improves the efficiency of heat exchange, has the coefficient of heat transfer
Height, it is less scaling the advantages of, working medium particularly relatively low for intraductal heat exchange coefficient.

Embodiment
Embodiment
According to Fig. 1, Fig. 2 and Fig. 3, a kind of 3 D deformation with internal-rib becomes space heat exchanger tube, including middle torsion
Curved tube section 2 and the circular straighttube section 1 at both ends, the distortion pipeline section 2 are formed by pipe through helically twisted, the distortion He of pipeline section 2
The multiple fins 3 of the inner wall even distribution of circular straighttube section 1, the fin 3 are uniformly and symmetrically distributed along ips, and along between pipe range direction etc.
Away from being uniformly distributed.
Wherein, the distortion pipeline section 2 and circular straighttube section 1 use integrated molding structure.The physical dimension of fin 3 and
Different sizes can be made as needed for spacing.The ratio of semi-minor axis length and pitch of the distortion pipeline section 2 can need and add according to operating mode
The appropriate adjustment of work requirement.The bore that distortion pipeline section 2 working medium flows into end is more than the bore of working medium outflow end, and interlude is smoothed
Cross.
Working media enters distortion pipeline section 2 from circular straighttube section 1, has both been produced in Bottomhole pressure to rotate to be principal character
Complex Flows, Secondary Flow promotion heat exchange is produced on main flow direction in pipe, and formed after the flowing of fin 3 after rib
Karman vortex street, flow disturbance is set further to strengthen, the superposition of two kinds of enhanced heat exchange effects is greatly promoted heat exchange, is had and is changed
Hot coefficient is high, it is less scaling the advantages of, working medium particularly relatively low for intraductal heat exchange coefficient.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment simultaneously is not used to limit
The scope of the claims of the present utility model, all equivalence enforcements or change without departing from carried out by the utility model, it is intended to be limited solely by this case
In the scope of the claims.
