Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
The fin that the embodiment of the present invention provides, for micro-channel parallel flow heat exchanger, above-mentioned fin is provided with confession
The through hole 11 that micro-channel flat 2 runs through, the length direction centrage of this through hole 11 and horizontal direction have folder
Angle.
It should be noted that the length direction centrage of through hole 11, refer to the length direction along through hole 11
The centrage extended, as shown in dotted line L in Fig. 1, this central axis is in the central shaft of through hole 11
Line.Horizontal direction, after referring to that above-mentioned fin is installed on micro-channel parallel flow heat exchanger, micro-channel parallel flow
Heat exchanger normally uses horizontal direction during placement, and the length direction of above-mentioned fin or width with
Above-mentioned horizontal direction parallel.Through hole 11 runs through for micro-channel flat 2, then show the length of micro-channel flat 2
Degree direction and the length of the centerline axis parallel of through hole 11, the width of micro-channel flat 2 and through hole 11
Degree direction is parallel.
It is understood that the angle of the length direction centrage of through hole 11 and horizontal direction is more than zero degree,
And less than 90 degree.The length direction centrage of through hole 11 and horizontal direction have angle, then through hole 11 phase
Horizontal direction is obliquely installed.Above-mentioned through hole 11 has two kinds of incline directions, can select according to actual
Selecting, this is not limited by the embodiment of the present invention.
The size and shape of above-mentioned through hole 11, needs to set according to the size and shape of micro-channel flat 2
Meter.Preferably, through hole 11 is mounting hole.
The fin that the embodiment of the present invention provides, is provided with the through hole 11 run through for micro-channel flat 2, and through hole
The length direction centrage of 11 and horizontal direction have angle, then micro-channel flat 2 is installed on above-mentioned fin
After, micro-channel flat 2 is consistent with the incline direction of through hole 11, when defrosting water flow to micro-channel flat 2,
Defrosting water can flow along micro-channel flat 2 under self gravitation effect, then avoid micro-channel flat 2
Stockpiling defrosting water, relatively prior art micro-channel flat 2 is compared along being horizontally disposed with, it is achieved that discharge in time
Frost water.
Meanwhile, the fin that the embodiment of the present invention provides, due to length direction centrage and the level of through hole 11
Direction has angle, then after micro-channel flat 2 is installed on above-mentioned fin, and micro-channel flat 2 and through hole 11
Incline direction consistent so that micro-channel flat 2 certain air agitation raw to air miscarriage, enhance
Heat exchange property.
In above-mentioned fin, the length direction centrage of through hole 11 and the angle of horizontal direction, can be according to reality
Needs are designed, and specifically, design concrete angle according to fin width and face velocity.Two
The angle of person is the biggest, is more easy to the flowing of defrosting water, but heat exchange property can reduce.In order to rationally arrange,
The length direction centrage of prioritizing selection through hole 11 and the angle of horizontal direction are not more than 30 °.Preferably,
Above-mentioned horizontal direction is the width of above-mentioned fin, and along the width through hole 11 of above-mentioned fin
At least two row, along a length direction through hole 11 at least row of fin.
In order to optimize technique scheme further, in above-mentioned fin, at least one exhausting hole 11 has to
Few first through hole and at least one second through hole, the first through hole and the second through hole are adjacent, the first through hole
Tilt to the bottom of fin near one end of the second through hole from the one end away from the second through hole, the second through hole
Tilt to the bottom of fin near one end of the first through hole from the one end away from the first through hole, and first leads to
Between hole and the second through hole, there is gap.As shown in figures 1 and 3.
It should be noted that the bottom of above-mentioned fin, refer to that above-mentioned fin is installed on micro-channel parallel flow and changes
After hot device, the bottom of fin when micro-channel parallel flow heat exchanger normally uses.Above-mentioned fin, the first through hole
With the second through hole in falling " eight " font, then it is installed on the first through hole and the second through hole when micro-channel flat 2
After, two micro-channel flat 2 are also in falling " eight " font, and two micro-channel flat 2 form drainage channel 3,
And two micro-channel flat 2 all draw defrosting water to drainage channel 3 so that defrosting water is by this drainage channel 3
Discharge.So, decrease the stop to defrosting water, accelerate the flowing of defrosting water；Meanwhile, also allow for
Gather defrosting water, further speed up the flowing of defrosting water.
Gap between width and the first through hole and second through hole of above-mentioned drainage channel 3 is equal.First
Gap between through hole and the second through hole is too small, then drainage channel 3 also can be too small, and water may be caused to flow out
Drainage channel 3 is the most difficult, and the air wide pre. drop of micro-channel parallel flow heat exchanger increases；First through hole and
Excesssive gap between second through hole, may result in the degradation of heat exchange performance of micro-channel parallel flow heat exchanger,
Gap size between first through hole and the second through hole should design according to actual needs.
Preferably, the gap between above-mentioned first through hole and the second through hole is more than 1.5mm.Draining is led to
The higher limit of the width in road 3, can be designed according to actual needs, and this is not limited by the embodiment of the present invention
Fixed.
It is understood that in above-mentioned fin, in an exhausting hole 11, it is possible to select to there are adjacent two
Through hole 11 can be in " eight " font distributions.
In above-mentioned fin, in an exhausting hole 11, can have two the first through holes and two the second through holes, the
One through hole and the second through hole one_to_one corresponding；Optional any one exhausting hole 11 there is the first through hole and second
Through hole.
In order to farthest improve drainage efficiency, in any string through hole 11, any two through hole 11
Incline direction identical, as shown in Figure 1.So, if two row through holes 11 exist the first through hole and second
Through hole, then other through holes of two row are respectively the first through hole and the second through hole so that drainage channel 3 and
The number of through hole 11 included in row through hole 11 is identical, and drainage channel 3 is along the length of above-mentioned fin
Direction is sequentially distributed and is sequentially communicated.
Preferably, in above-mentioned fin, two adjacent row through hole 11 axial symmetry are arranged, as shown in Figure 1.This
Sample, it is simple to micro-channel flat 2 is set, also allows for draining.
