Please refer to Fig. 5, Fig. 5 is the structural representation of first kind of specific embodiment of fin provided by the present invention.
In some application scenarios, owing to the reasons such as needs of restriction of being laid the space or structural design, flat tabular heat exchanger needs sometimes along header direction bending certain angle, to satisfy specific instructions for use.
Heat exchanger is when bending, the inboard spacing of its adjacent flat tube diminishes gradually, and outside spacing becomes big gradually, therefore can be compressed during in the bending inboard 101 of the fin between the adjacent flat tube 100 at heat exchanger bending, and the bending outside 102 can be stretched when heat exchanger bending, and inboard compression is dwindled outward gradually by interior, and the stretching in the outside is also by dwindling gradually inward outward, near the center, compression and tension approaches zero.
The areas that launch can be offset the area that inboard 101 compressions of fin bending diminish because the fin bending outside 102 stretches, therefore theoretically, heat exchanger after bending, can keep basically with bending before heat exchange property about the same.If but the fin at heat exchanger bending position still adopts complete rectangular fin, after actual bending, with the various drawbacks that inevitably occur mentioning in the middle of the background technology of the present invention.
For satisfying the needs of heat exchanger along the bending of header direction, the present invention improves the fin that is arranged on the bending part on the basis of existing fin structure, can offer rectangular slits 103 one in compressed bending inboard 101 at fin 100, this otch 103 is positioned at the centre position of fin 100 inboards substantially, extend inwards from the inner side edge edge of fin 100 always, its end is near the center of fin 100, the inboard of each straight portion on the same fin all has identical shaped and big or small otch 103, if observe along the flat tube length direction then can only see the otch 103 of a coincidence.
Above-mentioned otch 103 can adopt the machine cuts mode that middle one section is cut away after existing fin moulding, and this side that will be sheared then is installed in the heat exchanger bending inboard.
Because the existence of otch 103; the bending inboard of fin 100 can't form complete, stable supporting construction; when compression, do not resist the support force of bending; compare with complete fin structure; be compressed easily; thereby reduced the bending difficulty of heat exchanger to a great extent along the header direction; also reduced the bending technique higher requirement; and suitable bending dynamics can make the fin bending outside 102 gently be stretched; the protection fin bending outside 102 is not excessively stretched even is ruptured, and guarantees that heat exchanger air side heat exchange property remains on higher level.
In addition, because the existence of otch 103, heat exchanger is when bending, the otch of fin bending inboard 101 is closed gradually to be drawn in, compression back fin 100 has higher intact degree, can not produce problems such as irregular deformation, lodging, can avoid occurring problems such as ponding, frosting, and it is smooth and easy that intact fin structure can guarantee to blow over the circulation of air of heat exchanger, no matter therefore be that the heat exchanger that is provided with fin provided by the present invention all has higher heat exchange property as evaporimeter or heat pump outdoor unit heat exchanger etc.
For giving full play to the heat exchange property of fin, can on fin 100, offer window 104, the window and the otch 103 that wherein are positioned at fin bending inboard 101 slit logical.Because window 104 can increase heat exchange contact area and air mass flow, therefore can further improve the heat exchange property of fin 100.
Certainly, fin provided by the present invention is not limited to corrugated fin, can be any fin that its bending inboard has the trend of being compressed when heat exchanger bending.
Fig. 6 is the structural representation of second kind of specific embodiment of fin provided by the present invention.
This fin and first kind of specific embodiment are similar, and the main distinction is, the otch 103 of its bending inboard ' be isosceles triangle.Like this, its shearing displacement is not only little than rectangular slits 103, and when compression, the otch both sides of fin begin and can draw in gradually from triangular apex, finally close completely in together, have the intact degree higher than rectangular slits, also easier being compressed can allow littler radius bend and bending angle.
Fig. 7 is the structural representation of the third specific embodiment of fin provided by the present invention.
This fin is also similar with first kind of specific embodiment, and the main distinction is that its fin only offers window 104 in the bending outside, and window is not offered in otch 103 both sides of bending inboard.This is because the bending inboard of fin is in compressed position, and with respect to the bending outside, its stressing conditions and distortion more complicated are not offered the intensity that window can guarantee its position, otch both sides, have higher intact degree after guaranteeing to be compressed.
Fig. 8 is the structural representation of the 4th kind of specific embodiment of fin provided by the present invention.
This fin and the third specific embodiment are similar, the main distinction is, the bending outside of fin offers window 104, its bending inboard offer separately respectively in the both sides of otch window 104 ', the window of otch both sides and otch do not slit logical, so both can guarantee the intensity of otch both sides, can give full play to the heat exchange property of fin again.
Fig. 9 is the structural representation of the 5th kind of specific embodiment of fin provided by the present invention.
This fin and second kind of specific embodiment are similar, otch 103 ' triangular in shape, and the bending outside of fin offers window 104, and the main distinction is that its incision is not windowed.
Figure 10 is the structural representation of the 6th kind of specific embodiment of fin provided by the present invention.
This fin and the 5th kind of specific embodiment are similar, otch 103 ' triangular in shape, the bending of the fin outside offers window 104, the main distinction is, the otch upper and lower sides offer separately respectively window 104 ', to give full play to the heat exchange property of fin.
By above-mentioned six kinds of specific embodiment as can be known, offer the bending problem that otch can solve heat exchanger to a certain extent in fin bending inboard, but be subject to the concrete structure of heat exchanger, the angle that heat exchanger forms after the bending of header direction can not be too little, and it is comparatively suitable that this angle is controlled between 90 °-180 ° substantially.
The radius bend of the degree of depth of above-mentioned otch and width and heat exchanger is suitable, that is to say, the shearing degree of depth of otch and A/F decide according to the size of heat exchanger bending radius.This be because, if the otch of fin bending inboard is excessive, can influence the intensity and the waste material of fin on the one hand, another side can cause heat exchange property to descend because shearing displacement is excessive, and heat exchange area reduces; If the otch of fin bending inboard is too small, its inboard still has the part support force to exist when bending, shears not enough position after the bending and irregular deformation and lodging problem still can occur, and do not reach the purpose that reduces bending difficulty and guarantee heat exchange property.
According to mentioned above principle, can reasonably determine the dimensional parameters of otch.When radius bend was big, the bending of heat exchanger core body was inboard and outside distortion is all less, so the shearing degree of depth of otch is more shallow, and A/F is smaller; When radius bend hour, the bending of heat exchanger core body is inboard and outside distortion is all bigger, so the shearing degree of depth of otch wants dark, and A/F is wanted greatly.
Need to prove that the shape of otch is not limited to triangle or the rectangle in the above-mentioned embodiment, can also be other comparatively suitable shapes such as polygon.
Can be further improved fin mentioned above.
When the radius bend of heat exchanger hour, the bending outside distortion of heat exchanger core body is bigger, for avoiding the fin bending outside excessively to be stretched even tearing, can offer from outer side edges along the otch that extends inwards in the fin bending outside, its concrete shape and big I are with reference to above about the description of bending inner incision, can reduce heat exchange area though offer otch in the bending outside, stretch with transition even tear and compare, the heat exchanging Effect on Performance is less relatively.
Except above-mentioned bending fin, the present invention also provides a kind of heat exchanger, and this heat exchanger is provided with above-mentioned fin in its bending part along the header direction, and satisfying the needs of bending, and the complete fin that does not have otch is still adopted at other position.
Above-mentioned heat exchanger specifically can be a micro-channel heat exchanger, this is a kind of high-performance heat exchanger that adopts aluminum alloy materials to make, mainly apply to family expenses, light-duty business air conditioner and the freezing market of freezing, have compact conformation, heat exchange efficiency height, light weight, characteristics such as safe and reliable to operation, simultaneously can reduce client's integrated cost greatly, the structure of other each several parts please refer to prior art, and this paper repeats no more.
More than heat exchanger provided by the present invention and fin thereof are described in detail.Used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present invention.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
