Embodiment

Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.

Preferred embodiment one:

This preferred embodiment provides a kind of heat exchanger fin.As depicted in figs. 1 and 2, fin 1 includes the fin master being connected The flat tube groove 111 for wearing flat tube 2 is offered in body 11 and fin side 12, fin main body 11, in fin main body 11 and/or wing The surface on piece side 12 is provided with support member 101 with protruding above.Support member 101 is in arch bridge shape, is set on the two sides of support member 101 It is equipped with hatch frame, wind passage 102 of the hatch frame formation along the surface of fin 1.

The wind passage 102 formed between support member 101 and the surface of fin 1 be conducive to reduce fin windage, fin 1 it is comprehensive Close performance further to improve, while reducing wind flows through the noise produced during fin 1.

The fin bridge 112 of multiple arches is provided with fin main body 11.It is provided with out on the two sides of fin bridge 112 Mouth structure, wind passage 102 of the hatch frame formation along the surface of fin main body 11.

Multiple corrugation lobes portions 113 are provided with fin main body 11.Corrugation lobes portion 113 can be to flowing through fin 1 Wind carries out flow-disturbing, destruction boundary layer, enhanced heat exchange effect.Corrugation lobes portion 113 can be existing planar structure (closing knot Structure);Hatch frame can also be provided with the side in corrugation lobes portion 113, the hatch frame is formed along the table of fin main body 11 The wind passage 102 in face, fin windage is lowered while heat transfer effect is ensured.

Outwards turnover forms flange 114 at the edge of flat tube groove 111, it is ensured that welding is sufficiently used between fin 1 and flat tube 2 Contact area, overall structure is more firm after welding.

Multiple reinforcements 103 are provided with fin main body 11 and fin side 12, to increase the intensity of fin main body 11.Plus The shape of strengthening tendons 103 is not limited, and can be strip, block or other shapes.

Fin main body 11 and the intersection of fin side 12 formation drainage channel 104, it is ensured that condensation water can smooth discharge.

Preferred embodiment two:

This preferred embodiment provides a kind of heat exchanger fin, and its structure and preferred embodiment one are essentially identical.Fin includes The flat tube groove for wearing flat tube is offered in the fin main body being connected and fin side, fin main body, in fin main body and/or The surface on fin side is provided with support member with protruding above, and support member is in arch bridge shape, and opening is provided with the two sides of support member Structure, wind passage of the hatch frame formation along fin surface.

Difference is:Other structures (fin bridge, corrugation lobes are not provided with fin main body in addition to support member Portion, reinforcement etc.), i.e. fin main body is planar structure, sacrifices part heat exchange property to exchange lower fin windage for.

Preferred embodiment three:

This preferred embodiment provides a kind of heat exchanger.As shown in Figure 3 and Figure 4, the heat exchanger includes a plurality of flat tube 2 and multi-disc Fin 1 as described in preferred embodiment one or two, flat tube 2 is caught in flat tube groove 111.

Support member is spaced apart by adjacent two panels fin, it is ensured that have enough distinguished and admirable through fin, it is to avoid because of condensation water Frosting and cause overall performance decay serious.

Positive pile row constitute fins set to every fin 1 successively, and a plurality of flat tube 2 is respectively clamped into the flat tube groove 111 of fins set, Distance between fin is equal to the height of support member;It is a plurality of or, forward direction-back span pile row constitute fins set to multi-disc fin 1 successively Flat tube 2 is respectively clamped into the flat tube groove 111 of fins set, the bridge of the support member 101 in fin main body 11 and/or fin side 12 High h, fin pitch of fins Fp, fin thickness δ f threes meet relationship below:H=(Fp- δ f)/2.For example fin pitch of fins Fp is 1.6mm, fin thickness δ f are 0.08mm, then stator is 0.76mm away from the high h of bridge.

The fin bridge 112 being additionally provided with fin main body 11 on the fin bridge 112 of arch, adjacent two panels fin 1 is convex to Identical, the wind now passed through is evenly.

The assembling flow path of flat tube and fin:As shown in figure 5, the fin 1 through punch press machine-shaping is reached at lamination mechanism, point Odd column fin 1 is converged to first layer, even column fin 1 is converged into the second layer by layer mechanism.Then because fin is weighed in itself The unbalanced one end for make it that fin is heavier of power is overturn down, is just stuck in after 90 ° of upset on the fin upset edge of a knife;Then through conveying Mechanism 3 sends into fin material-gathering device, and flat tube 2 most is pressed into fin 1 through fin pressurizing unit afterwards.After installation, the court of last layer fin 1 Under support member can just push up the support member of next layer of fin 1 upward, and ensure that heat exchanger main part interposition The corrugation lobes portion 113 put and fin bridge 112 are towards same direction.

Preferred embodiment four:

This preferred embodiment provides a kind of heat exchanger, and its structure and preferred embodiment three are essentially identical.The heat exchanger includes Flat tube and the fin as described in preferred embodiment one or two;Flat tube is caught in flat tube groove.

Difference is:The fin bridge on the fin bridge of arch, adjacent two panels fin is additionally provided with fin main body It is convex to opposite.Now the air force between each fin differs, it is ensured that fin windage is smaller at portion.
