To described precalculated position 111, the angle that described spine 101 and described alar part 107 tilt with respect to reference plane P is greater than 0 and be less than or equal to 50 degree, preferably is less than or equal to 25 degree from first side 103.From 111 to second sides 105, described precalculated position to, the angle that described spine 101 and described alar part 107 tilt with respect to reference plane P is greater than 0 and be less than or equal to 50 degree, preferably is less than or equal to 25 degree.
Among the embodiment shown in Fig. 4 to 6, the spine 101 of fin 100 is a linear pattern, and two alar parts 107 of fin 100 are linear pattern.Fin 100 shaped design are become " A " type, and condensed water and defrost water can be discharged along alar part 107 direction W smoothly owing to the effect of gravity.Air can blow on direction A.It is more smooth and easy that this structure is discharged condensed water and defrost water, alleviated the problem of the impeded drainage that exists in the existing fin structure, promoted heat exchange property and system effectiveness then.
Figure 13 is the stressed schematic diagram of the globule on the inlet air side fin 100, and α represents fin and horizontal direction angle among the figure.If P is the thrust of inlet air to water droplet, mg is the gravity G that water droplet is subjected to, and f is the coefficient of friction (getting f=0.15) of fin surface and water, and N is that water droplet is at fin surface applied pressure=mg*cos α.
According to Figure 13, the stressed pass of water droplet is:
Being parallel to fin 100 surfaces is G*sin α to the partical gravity of downside,
Be parallel to the frictional force F=fN=f*G*cos α that fin surface makes progress,
The thrust that forms on the water droplet surface when flowing on the wind direction: P=π R
2v
2ρ
Empty/ 2,
Wherein, the ρ sky is the density of air, and R is the arc radius on water droplet surface, the v air velocity.
As condensed water is flowed down smoothly, then need satisfy G*sin α>F+P
Wherein: G=(4/3) π R
3ρ

Above every formula is brought among G*sin α>F+P, obtains fin and horizontal direction angle α need satisfy following requirement:
The wind direction of fin air side, the partical gravity direction that is parallel to fin is identical, and water droplet only needs overcome friction just can flow, that is:
G*sin α+P>F, obviously, with the angle α of inlet air side, this requirement can be satisfied fully in the air side, so to the air side angle, only need and identical the getting final product of inlet air side angle [alpha].
As selection, shown in Fig. 7 to 8, to described precalculated position 111, each in described spine 101 and the described alar part 107 roughly is crooked or circular arc from described first side 103.Promptly from described first side 103 on the direction in described precalculated position 111, each in described spine 101 and the described alar part 107 roughly is crooked or circular arc.To described second side 105, each in described spine 101 and the described alar part 107 roughly is crooked or circular arc from described precalculated position 111.Promptly from described precalculated position 111 on the direction of described second side 105, each in described spine 101 and the described alar part 107 roughly is crooked or circular arc.
Shown in Fig. 9-12, described heat exchanger 10 comprises first row's heat exchanger 17 and the second row's heat exchanger 19 that is arranged side by side, the space 150 of second side 105 of the fin 100 of second side 105 of the fin 100 of described first row's heat exchanger 17 and described second row's heat exchanger 19 between first row's heat exchanger 17 and second row's heat exchanger 19.
For the heat exchanger 10 shown in Fig. 9-12, fin 100 is that second side 105 is roughly the highest, that is, described precalculated position 111 overlaps with second side 105.As shown in the figure, air direction A blows, and drainage direction is direction W.The draining of such first row's heat exchanger 17 can be discharged from the inlet air side of first row's heat exchanger 17, and the condensed water of second row's heat exchanger 19 is then discharged from the air side of second row's heat exchanger 19.Can avoid the condensed water of first row's heat exchanger 17 to blow on second row's heat exchanger 19, accumulation too much influences its draining on second row's heat exchanger 19, influences heat exchange then.
