The utility model is achieved through the following technical solutions,
The utility model includes：The first end face and second end face be arrangeding in parallel up and down, wherein：First end face and the second end
Face is connected, connected by outer convex inclined plane in fin air side by evagination arcwall face in fin inlet side；The first end face and
Vertical some port plates are provided between second end face；
The outer convex inclined plane includes that the first outer convex inclined plane being connected respectively with first end face, second end face and the second evagination are oblique
Face；
The first described outer convex inclined plane and the second outer convex inclined plane size, structure is identical and is connected with each other.
Angle is α, 85 ° of 30 °≤α ＜ between the first described outer convex inclined plane and the second outer convex inclined plane.
Preferably, the first described outer convex inclined plane and the second outer convex inclined plane are seamlessly transitted by fillet.
Preferably, the first described outer convex inclined plane is seamlessly transitted with first end face by fillet, and the second described evagination is oblique
Face is seamlessly transitted with second end face by fillet.
Preferably, the described first outer convex inclined plane and the second outer convex inclined plane respectively with flat tube in one piece of port plate it is upper and lower

Specific embodiment
Embodiment of the present utility model is elaborated below, the present embodiment is with technical solutions of the utility model as preceding
Put and implemented, give detailed implementation method and specific operating process, but protection domain of the present utility model is not limited
In following embodiments.
Embodiment 1
As shown in figure 1, the present embodiment includes：The first end face 1 and second end face 2 be arrangeding in parallel up and down, wherein：First end
Face 1 and second end face 2 are connected in the inlet side of fin 7 by evagination arcwall face 3, are connected by outer convex inclined plane in the air side of fin 7,
As shown in Figure 2；Vertical some port plates 4 are provided between the first end face 1 and second end face 2；
The outer convex inclined plane is included outside the first outer convex inclined plane 5 and second for being connected respectively with first end face 1, second end face 2
Convex inclined plane 6；
The first described outer convex inclined plane 5 is with the size of the second outer convex inclined plane 6, structure is identical and is connected with each other.
Angle is α, 85 ° of 30 °≤α ＜ between the first described outer convex inclined plane 5 and the second outer convex inclined plane 6.
Preferably, the first described outer convex inclined plane 5 and the second outer convex inclined plane 6 are seamlessly transitted by fillet.
Preferably, the first described outer convex inclined plane 5 is seamlessly transitted with first end face 1 by fillet, the second described evagination
Inclined-plane 6 is seamlessly transitted with second end face 2 by fillet.
Preferably, the described first outer convex inclined plane 5 and the second outer convex inclined plane 6 respectively with flat tube in one piece of port plate 4
Upper and lower ends are connected, and are seamlessly transitted by fillet.
The cross-sectional length of the flat tube is L, 13mm≤L ＜ 22mm；The cross section width of the flat tube be W, 2.4mm≤
