Be provided at circumferentially spaced.
The heat exchange fin that the utility model embodiment provides, when heat exchange fin is applied into finned heat exchanger, due to base
Heat exchange pore 11 on piece 1 is set close to leeward side, is reduced the tail area that air is formed after heat exchanger tube and is fallen on the substrate 1
Area；Multiple patch 12 are additionally provided with substrate 1, the opening 111 of patch 12 is multiple towards the edge of the length direction of substrate 1
Patch 12 is provided at circumferentially spaced around heat exchange pore 11, the flowing of the attachment without separation that patch 12 can be destroyed near heat exchanger tube,
And more air are directed to the leeward side of heat exchanger tube, the tail area of heat exchanger tube leeward side is further shorten, improves changing for fin
The thermal efficiency.
Alternatively, above-mentioned patch 12 can be window, bridge piece etc., and the flowing resistance of bridge piece is small, and therefore, the utility model is implemented
Example in patch 12 be bridge piece, the length direction of bridge piece is identical with the length direction of substrate 1, and the length of bridge piece from exchange heat pore 11
Center to the width both sides of substrate 1 gradually increase, or bridge piece quantity from heat exchange pore 11 center to the width side of substrate 1
Gradually increase to both sides, or the length of bridge piece and quantity gradually increase from center to the width both sides of substrate 1 of heat exchange pore 11
Add.What bridge piece can open up on substrate 1 is more, and increases close to quantity of the both sides of the width of substrate 1 along bridge piece and/or quantity
Add, help for air to be directed at the leeward side of heat exchanger tube, reduce the tail area of heat exchanger tube, improve the heat transfer effect of fin.
Because the patch 12 opened up on substrate 1 is more, the structural strength of fin can be made relatively low.The wing of the utility model embodiment
Piece is also included along the length sides of substrate 1 along the bending structure 2 set, and the bending structure 2 includes the first kink 21 and the second bending
Portion 22, wherein, the first kink 21 is formed from the side edge of the width of substrate 1 towards away from the bending extension of bridge piece direction, the
Two kinks 22 are bent to form from the outer end of the first kink 21 towards the outside of substrate 1, as shown in Figure 3.The bending structure 2 can increase
The structural strength of fin, and increase the heat exchange area of fin, so as to improve heat exchange efficiency of the fin on length sides edge.Alternatively,
The length sides edge of the side of substrate 1 is provided with above-mentioned bending structure 2, or the length sides edge of the both sides of substrate 1 is provided with above-mentioned bending structure 2,
The utility model embodiment uses the scheme of the latter, and the structural strength of heat exchange fin is higher.
Alternatively, the bearing of trend of the second kink 22 is parallel with the width of substrate 1, or the second kink 22 is from
The outer end of one kink 21 extends towards the direction away from bridge piece, or prolongs from the outer end of the first kink 21 towards the direction close to bridge piece
Stretch.If the second kink 22 extends from the outer end of the first kink 21 towards the direction away from bridge piece, or from the first kink 21
Outer end extends towards close to the direction of bridge piece, and fin part commutation of the air in heat exchanger is more, and wind speed loss is larger, heat exchanger
Air output is smaller, it is therefore preferred that using the design parallel with the width of substrate 1 of the bearing of trend of the second kink 22
Scheme.Alternatively, the angle α between the first kink 21 and the second kink 22 can be obtuse angle, right angle or acute angle.Cause second is curved
The bearing of trend of folding part 22 intersects with the width of substrate 1, and the angle α between the first kink 21 and the second kink 22 is
Acute angle or right angle, when air passes through bending structure 2, close to fin surface air layer by the first kink 21 resistance compared with
Greatly, the flowing velocity of boundary layer air is reduced, so as to reduce the heat exchange efficiency of heat exchange fin.It is therefore preferred that using
Angle α between one kink 21 and the second kink 22 is the design at obtuse angle, as shown in figure 3, the width of substrate 1
Transition between edge and the first kink 21, between the first kink 21 and the second kink 22 is smoother, and reduces curved
Folded structure 2 is to the resistance of incoming air, so as to improve the heat exchange efficiency of heat exchange fin.Preferably, the utility model embodiment is adopted
It is parallel with the width of substrate 1 with the bearing of trend of the second kink 22, and the first kink 21 and the second kink 22 it
Between angle α be obtuse angle scheme.
The edge of above-mentioned heat exchange pore 11 is provided with annular flange 13 for one week, and the diameter of the annular flange 13 is towards away from substrate 1
Surface gradually increase, such as annular flange 13 is taper or as shown in Figure 3 horn-like, is easy to heat exchanger tube inserting heat exchanger tube
In hole 11, facilitate the assembly operation of heat exchanger.
If the spacing on fin between adjacent heat exchange pore 11 is excessive, to ensure the heat exchange effect using the heat exchanger of the fin
Rate, the volume of heat exchanger are larger；If the spacing on fin between adjacent heat exchange pore 11 is too small, using the heat exchanger of the fin
Windage is larger, influences heat exchange efficiency.Therefore, reference picture 4, it is preferable that in the utility model embodiment in adjacent heat exchange pore 11
The length L of heart line span is 16~17.5mm, and the windage using the heat exchanger of the fin is smaller, and the heat exchange effect of fin
Rate is also higher.
Similarly, the width of fin is excessive, and the volume of heat exchanger is too big；The width of fin is too small, the heat exchange efficiency of heat exchanger
It is relatively low, therefore, reference picture 3, it is preferable that the width W of fin in the utility model embodiment1Span be 16~22mm,
And the width W of the second kink 222Span be 1.2~2mm, ensure that fin has higher structural strength, and fin
The heat exchange efficiency of length edge is higher.Alternatively, the span of bridge piece width is 1.0~1.5mm.
On the basis of above-described embodiment, the angle α between the first kink 21 and the second kink 22 is excessive, fin
Intensity is smaller；Angle α between first kink 21 and the second kink 22 is excessive, and the windage of heat exchanger is larger.It is therefore preferable that
Ground, the span of the angle α in the utility model embodiment between the first kink 21 and the second kink 22 for 145 °~
160°。
In addition, the height of bridge piece can not set too high, the structural strength of fin can be influenceed；Or the height of bridge piece is spent
It is low, influence the windage of heat exchanger.Therefore, reference picture 3, it is preferable that the height H of bridge piece value model in the utility model embodiment
Enclose for 0.5~0.8mm.
