Specific embodiment
Embodiments of the invention are described in detail below, but the present invention can be defined by the claims and
The multitude of different ways of covering is implemented.
Referring to shown in Fig. 2 to Figure 11, the invention provides a kind of fin, including fin body 1, positioned at wing
Flat tube mounting groove 2 on piece body 1 and the week side of boss positioned at flat tube mounting groove 2 are simultaneously connected in fin body 1
Trough rim clout 3, trough rim clout 3 includes connecting portion 4 and separation unit 5, and connecting portion 4 is connected to fin body
1 edge, and being turned down towards the side of fin body 1, separation unit 5 is connected on connecting portion 4, and towards wing
The side turnover of piece body 1, forms vertical positioning flange of the height higher than the width of flat tube mounting groove 2.
In fin provided by the present invention, trough rim clout 3 is processed so that trough rim clout 3
A part is connected with fin body 1, and another part is separated with fin body 1, and is utilized and fin body 1
The separation unit 5 of separation forms vertical positioning flange of the height higher than the width of flat tube mounting groove 2, so that wing
The positioning flange height of piece is no longer influenced by the limitation of flat tube thickness, and adjacent fins effectively can be positioned,
So as to the orientation distance between adjacent fins is effectively ensured, the service behaviour of fin is improve.
Separation unit 5 is separated along the length direction of fin body 1 with fin body 1.Because trough rim clout 3 is
Cut out from flat tube mounting groove 2, therefore trough rim clout 3 is shaped as strip, if by strip
Trough rim clout 3 and fin body 1 between cut open to form separation unit 5, and separation unit 5 is turned down,
Positioning height higher can be just realized using the length of trough rim clout 3, so that trough rim clout 3 is turned over
Positioning height after folding is no longer influenced by the influence of the width of trough rim clout 3, can both make full use of on fin
Trough rim clout, can still ensure that positioning height is unrestricted in the case where flat tube thickness is less than positioning height again
System, and the structure of fin surface will not be destroyed, the draining and defrosting of fin not being interfered with, can at utmost carry
Drainability high and exchange capability of heat.
It is the first embodiment of fin of the invention with reference to shown in referring to Fig. 2 to 4, in the present embodiment,

To turnover, and it is sticked in the outside of connecting portion 4, the second flanging 7 is along the top of the first flanging 6 to fin sheet
The place rollover folding of body 1.Adjust the length of the first flanging 6, you can the positioning height between regulation fin,
And first the length of flanging 6 will not be influenceed by the width of trough rim clout 3, therefore wing can be effectively ensured
Positioning height between piece.
Second flanging 7 to rollover folding where fin body 1, and the second flanging 7 top surface and fin body 1
Surface it is parallel, it is ensured that the second flanging 7 can between adjacent fin body 1 have it is bigger
Area of bearing, forms more stable support.
First flanging 6 relative to connecting portion 4 along 45 degree of diagonal doublings, and along perpendicular to fin body 1
Direction turns down, and the second flanging 7 is at a right angle relative to the first flanging 6, the top of connecting portion 4 and the second flanging
7 bottom connection is touched.When the second flanging 7 is formed to fin and supported, can be by connecting portion 4 pairs second
Flanging 7 forms support, improves the support strength of the second flanging 7.
The vertical positioning flange of the both sides of flat tube mounting groove 2 is diagonally set in the both sides of flat tube mounting groove 2, can
Two ends between guarantee adjacent fins along its length are respectively provided with stabilization support, keep the interval knot between fin
Structure is more uniform and stable, so as to improve the stability of whole heat exchanger.
With reference to referring to shown in Fig. 5 to Fig. 8, according to the second embodiment of the present invention, separation unit 5 includes first
The flanging 7 of flanging 6 and second, the first flanging 6 is reversely turned down relative to the direction that connecting portion 4 is turned down, and is pasted
Be located at the outside of connecting portion 4, the second flanging 7 along the first flanging 6 place side from top to fin body 1
Turnover.
Separation unit 5 also includes the 3rd flanging 8 and Fourth Fold 9, and the 3rd flanging 8 is connected to the second flanging 7
Afterbody, and turned down back towards the first flanging 6 relative to the second flanging 7, Fourth Fold 9 is connected to the 3rd
Flanging 8 is turned down near one end of the first flanging 6 along the direction in opposite direction with the turnover of the first flanging 6,
The end of Fourth Fold 9 extends to the surface of fin body 1.
3rd flanging 8 becomes placed against, the 4th relative to the second reversely turnover of flanging 7 with the second flanging 7
Flanging 9 becomes placed against relative to the first reversely turnover of flanging 6 with the first flanging 6, can form bilayer
Turnover structure such that it is able to improve the structural strength of positioning flange, it is ensured that the positioning branch of stabilization is formed to fin
Support.
With reference to shown in referring to Fig. 9 and Figure 10, according to the third embodiment of the invention, connecting portion 4 is located at flat tube
The arc link position of mounting groove 2, separation unit 5 is connected to the end of connecting portion 4, and separation unit 5 included
The connection flanging 7 of side 10 and second is crossed, transition connects side 10 and extends along the turnover direction of connecting portion 4, and by
Arc-shaped transition is straight panel shape, and the second flanging 7 is from the end on transition connection side 10 to the outside of flat tube mounting groove 2
Turnover.
In the present embodiment, by the use of the arc attachment structure of one end of flat tube mounting groove 2 as trough rim clout 3
Connecting portion, then extended to the other end of flat tube mounting groove 2 from arc connecting portion using trough rim clout 3
Part while the turnover of arc connecting portion is got up, will be connected on arc connecting portion as separation unit 5
Separation unit 5 turned down also along the direction that arc connecting portion is turned down, due to herein be arcuate structure, be
Ensure after turning down and completing, supporting plane can be formed at the Support Position of vertical positioning flange, because
This is processed for the transition connection side 10 that arc connecting portion is connected, and transition is connected side 10 and is formed gradually
Structure changes so that the part being connected with arc connecting portion is the arcuate structure matched with arc connecting portion,
The part being connected with the second flanging 7 is the straight panel shape structure matched with the second flanging 7, while make use of
The characteristics of grading structure so that transition connection side 10 has more preferable support strength relative to straight panel shape structure,
Improve the support strength of vertical positioning flange.
In order to further improve the support strength of the vertical positioning flange that trough rim clout 3 is formed, herein perpendicular
Can also be used and second embodiment identical double flare structure to positioning flange.In the structure shown here, separate
Portion 5 can also include the 3rd flanging 8 and Fourth Fold 9, the 3rd flanging 8 from the end of the second flanging 7 to
Arc connecting portion 4 is reversely turned down, and Fourth Fold 9 is from the end of the 3rd flanging 8 to the surface of fin body 1
Turnover, and the surface of fin body 1 is extended to, so that the trough rim clout 3 of the present embodiment can also shape
Into double-deck turnover structure, the structural strength of vertical positioning flange can be strengthened.
It is the fourth embodiment of fin of the invention, in the present embodiment, trough rim with reference to shown in Figure 11
Clout 3 includes main part 11 and lengthening part 12, and with flat tube mounting groove 2 as boundary, main part 11 is located at fin
The place side of body 1, lengthening part 12 is located at the adjacent fins body 1 place side adjacent with fin body 1, plus
