Specific embodiment：
The invention will be further described below in conjunction with the accompanying drawings：
By shown in Fig. 1 to Fig. 9, inside and outside this kind, Double helix is wandered about as a refugee heart separate type heat exchanger, including a pair of inlet-outlet connector 1 and suitable
The secondary some straight lengths being connected between the pair of inlet-outlet connector and some bend loss, described inlet-outlet connector, Ruo Ganzhi
Pipeline section and some bend loss by outer tube 6 nested with inner tube 4 after constitute, it is unique in that：In the inner tube 4 of described straight length
There is an interior arm 2, be fixed with one group of inner screwy fin 3, the outer rim of described inner screwy fin and described straight tube around described interior arm
The inwall of the inner tube 4 of section touches；Outer wall around the inner tube 4 of described straight length is fixed with one group of external spiral piece 5, described external spiral
The outer rim of piece is touched with the inwall of the outer tube 6 of described straight length.
Further, it is designed with shoulder, right in the inner tube of inlet-outlet connector 1 and in the annular space of inner tube and outer tube formation
Answer tube chamber shunting cylinder and outer lumen shunting torus, said inner tube chamber shunting cylinder and outer tube in fixing respectively at shoulder
Uniformly have, on chamber shunting torus, the hole passing through for medium.Described shunting body as shown in Figure 2 and Figure 9, plays shunting vibration damping
With centralizing function, require the area of passage of part flow arrangement to be greater than the area of passage between flight simultaneously, medium so can be made to exist
In flight, abundant eddy flow, does not interspace, and strengthens heat transfer.
In addition, the inwall of the inner tube 4 of described straight length has the thread groove screwing in for inner screwy fin 3, the spiral shell of inner screwy fin 3
Swing angle and pitch are consistent with the helical angle of corresponding thread groove and pitch, with realize the screw-in of described inner screwy fin, fixation with
Sealing；The inwall of the outer tube 6 of described straight length also opens the thread groove screwing in for external spiral piece 5, the helical angle of described external spiral piece
Consistent with the helical angle of corresponding thread groove and pitch with pitch, to realize described external spiral piece screw-in, fixation and sealing；Described
Difference between 20 °～40 °, between the width of corresponding thread groove and the thickness of flight for the liter angle range of inside and outside flight
Scope is between 5 millimeters～15 millimeters.
Additionally, the outer outer tube layer of described inlet-outlet connector, some straight lengths and some bend loss all has a heat-insulation layer 10.
It is the external spiral runner in flowing for the heating medium between the outer wall of the inwall of outer tube 6 and inner tube 4, the inner chamber of inner tube 4
For the internal coiling runner of cooling media flow, one of the pair of inlet-outlet connector 1 inlet-outlet connector as hot import and
Cold outlet, another inlet-outlet connector then exports and cold import as heat, so that cold and hot two media realizes counter-current flow.
During use, the specific work process of this device is as follows：
After using cooperatively with medium accelerator, cold and hot medium enters heat exchanger from inlet-outlet connector, and all has certain initial velocity
Degree.Thermal medium enters external spiral runner, flowing of spinning in outer flight by part flow arrangement, and cold medium passes through part flow arrangement
Enter internal coiling runner, flowing of spinning in inner screwy fin, two media realizes counter-current flow.So, by helical flow
Centrifugal action, the part that in thermal medium in external spiral piece, temperature is high, density is little, enthalpy is high is drawn close to center, that is, draw close in inner tube
Outer wall, the part that in the cold medium in internal coiling, temperature is low, density is big, enthalpy is low is drawn close to side wall, that is, draw close in inner tube wall,
Inner tube inside and outside wall heat transfer temperature difference so can be increased, be conducive to cold and hot medium fully to carry out heat exchange, effectively improve heat exchange effect
Rate.After the completion of heat exchange, cold and hot medium flows out from outlet connection.
