Description
Technical field
The present invention relates to a kind of self-locking structure of power station air cooling heat-exchanging tube bundle fin, belong to power station air cooling technical field.
Background technology
The heat-exchanging tube bundle of power station air cooling system is passed through frequently with a kind of fin poling technology, and multilayer fin is stacked, then with one
Root or many heat exchanger tubes reuse auxetic technology and fix heat exchanger tube and fin, eliminate between the two through hole reserved on fin
Gap, so as to improve heat exchange efficiency.Because fin is thin and flexible, bending deformation easy to break, mutual hole can not be complete when stacking for fin
Full alignment, makes troubles to the work of rising of poling and drawing；And due to lacking mutual constraint between fin, cause fin and heat exchanger tube
Between fit defective tightness, in addition to the heat exchange property of influence air cooling system, in gap location, heat exchanger tube and air contact, easily by oxygen
Change to reduce the life-span.
The content of the invention
The technical problem to be solved in the present invention is：Alignment between each fin perforate is kept there is provided one kind, between fin
Mutually constraint, ensure that fin is fitted the self-locking structure of close power station air cooling heat-exchanging tube bundle fin with heat exchanger tube, solves wing
It can not be brought into close contact between piece and fin, between fin and heat exchanger tube, so that the problem of influenceing heat exchange efficiency and service life.
In order to solve the above-mentioned technical problem, the technical scheme is that there is provided a kind of power station air cooling heat-exchanging tube bundle fin
Fin perforate on self-locking structure, including fin, it is characterised in that described fin perforate root is provided with shrinkage pool, shrinkage pool
The curl around punching hole that matches provided with internal diameter and heat exchanger tube external diameter of bottom, the top of curl around punching hole is provided with vertical quadric flanging,
The size of the maximum outside diameter of quadric flanging and shrinkage pool internal diameter matches.
Preferably, boss is provided with around described shrinkage pool.
Preferably, the quadric flanging between adjacent fins is connected with shrinkage pool matching.
Preferably, the aperture on described quadric flanging close to curl around punching hole side is identical with the aperture of curl around punching hole, and two
The aperture away from curl around punching hole side is more than the aperture of curl around punching hole on secondary flange, and the aperture of shrinkage pool is more than the hole of curl around punching hole
Footpath.
Instant invention overcomes the deficiencies in the prior art, it is ensured that fin keeps right between each fin perforate when stacking
Together, mutually constrained between fin, the automatic locking fin during drawing is risen, and utilize high tension force, it is ensured that fin and heat exchanger tube
Close and self-locking structure the stability of laminating.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the self-locking structure of power station air cooling heat-exchanging tube bundle fin；
Fig. 2 is a kind of use schematic diagram of the self-locking structure of power station air cooling heat-exchanging tube bundle fin.
Embodiment
To become apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The present invention is a kind of self-locking structure of power station air cooling heat-exchanging tube bundle fin, as shown in figure 1, it is included on fin
Fin perforate 1, the root of fin perforate 1 is provided with shrinkage pool 5, and the bottom of shrinkage pool 5 is provided with the perforate that internal diameter matches with the external diameter of heat exchanger tube 6
Flange 3, the top of curl around punching hole 3 is provided with vertical quadric flanging 2, the maximum outside diameter of quadric flanging 2 and the size of the internal diameter of shrinkage pool 5
Match.Boss 4 is provided with around shrinkage pool 5.Quadric flanging 2 between adjacent fins is connected with the matching of shrinkage pool 5.Quadric flanging 2
The upper aperture close to the side of curl around punching hole 3 is identical with the aperture of curl around punching hole 3, the remote side of curl around punching hole 3 on quadric flanging 2
Aperture is more than the aperture of curl around punching hole 3, and the aperture of shrinkage pool 5 is more than the aperture of curl around punching hole 3.
The height of curl around punching hole 3 and quadric flanging 2 determines the spacing between adjacent fins.
As shown in Fig. 2 when fin is stacked, the quadric flanging 2 of the wherein a piece of fin (i.e. the second fin 8) of adjacent two fin is inserted
In the shrinkage pool 5 for entering another fin (i.e. the first fin 7), therefore self-locking is realized during heat exchanger tube 6 draws and risen.Fin is passed through and changed
After heat pipe 6, strengthened using high tension force on the inside of the self-locking structure of the present invention.
Alignd between the fin perforate that each fin can be kept when stacking using the fin of the present invention, during drawing is risen
Close laminating is automatically formed, is coordinated by the self-locking of the quadric flanging and shrinkage pool of adjacent fins, realizes the automatic of fin perforate
Control is constrained between alignment and fin.Ensure the efficient uniform of tube bank heat transfer, heat transfer property is met expected design.
Prior art and the difference using the art of this patent (under the conditions of same design)：
The use of the coefficient of heat transfer K after prior art construction is~47kw/m2*k；And use the heat exchange after the structure of the present invention
COEFFICIENT K is~51kw/m2*k；Using the structure of the present invention than improving~10% using the efficiency of prior art construction.
