Referring to the mixed type fin that Fig. 4, the embodiment of the present invention are provided, including fin body 1, the fin body 1 is wrapped Include the first fin part 11 and the second fin part 12 being arranged in order (as shown by arrows in FIG.) along air inlet direction, first fin Portion 11 forms bending structure and without cracking 13, and second fin part 12, which is formed with, cracks 13.
Mixed type fin provided in an embodiment of the present invention, since fin edge air inlet direction is divided into the first fin part 11 and second Fin part 12, wherein the first fin part 11 forms bending structure and without cracking 13, and frosting substantially concentrates on the air inlet of fin Side, and in leeward side influences since air mass dryness fraction such as rises at the factors, there is no frost.Therefore, in low-temperature heating work During condition, due to inlet side the first fin part 11 be without crack 13 fin, frosting is also less, to the first fin part 11 Heat exchange property influence is smaller, and the second fin part 12 of leeward side there is no since the factors such as air mass dryness fraction rising influence Frost, thus select with crack 13 fin, can increase heat exchange property of the fin under nominal condition.It is simultaneous as a result, Heat exchange property of the air-conditioner fin under nominal condition and under low-temperature heating operating mode has been cared for, while has reduced product cost.
It should be noted that for convenience of description, illustrations chain lines show the first fin part 11 and second The approximate location in 12 line of demarcation of fin part;In addition, the bending structure that the first fin part 11 is formed can be smooth bending structure (such as ripple struction) or the bending structure (such as hierarchic structure) for having bending crest line.
Specifically, as shown in Fig. 5, Fig. 6, Fig. 7, first fin part 11 can be corrugated structure or such as Fig. 8, scheme 9th, straight ladder-type structure shown in Fig. 10.And the first fin part 11 is complete fin, is not provided with any crack thereon 13 engraved structures.Due to the first fin part 11 be complete fin, surface texture is smooth, therefore its windage very little, frosting also compared with It is few, therefore can ensure the synthesis heat exchange property of the fin in low-temperature heating operating mode.Stairstepping is used to form in first fin part 11 The folding line of structure preferably with air inlet direction it is vertical, thus can augmentation of heat transfer, improve heat exchange property.The folding line of ladder-type structure It is also an option that it is in the angle less than 90 degree with air inlet direction.
As shown in Fig. 8, Fig. 8 a, Fig. 6, Fig. 6 a, cracking for the second fin part 12 13 can crack for window;Or such as Fig. 7, figure Bridge-type shown in 7a, Fig. 9, Fig. 9 a is cracked.Wherein, the heat conduction reinforced effect of bridge-type slitted fin is less than the biography of window slitted fin Heat strengthen effect, but correspondingly, the windage of bridge-type slitted fin again smaller than the windage of window slitted fin, therefore, can be according to reality Border is selected.
As shown in Fig. 5, Fig. 5 a, Figure 10, Figure 10 a, cracking for the second fin part 12 13 can also be that through-thickness runs through The hollow out item seam of the fin body 1, cracks relative to window and cracks with bridge-type, hollow out item is stitched along the thickness side of fin body 1 It is unobstructed to no protrusion, therefore windage is cracked relative to window or bridge-type is cracked smaller.
Specifically, as shown in Fig. 5, Fig. 5 a, Figure 10, Figure 10 a, the second fin part 12 can be set as corrugated structure, and Hollow out item seam is opened up on corrugated structure.For heat exchange air-flow when flowing through corrugated structure surface, heat exchange air-flow will be from as a result, It is passed through in hollow out item seam, so as to interrupt the boundary layer of corrugated structure surface formation so that the boundary layer on corrugated structure surface It is overall thinning, the disturbance of heat exchange air-flow is increased in this way, is improved heat exchange stream turbulence, is made heat exchange air-flow and fin heat exchange amount Increase, so as to improve heat exchange property of the corrugated fin under nominal condition, meanwhile, in low-temperature heating operating mode, corrugated knot The hollow out item seam opened up on structure can also reduce the frost layer accumulation on corrugated fin surface.It cracks compared to bridge-type and cracks with window, hollow out Item seam is to form the structure hollow out cracked around 13, and in this way if region frosting near hollow out item seam, frost can head The position of hollow out can be first filled up, in the case of identical frosting degree, hollow out item seam frosting thickness is most thin, it is not easy to air duct is blocked, The windage that it is out-of-date that exchanging air circulates is minimum, so as to which fin be made to still maintain higher heat exchange property under low-temperature heating operating mode.
Wherein, the extending direction of hollow out item seam can be there are many selecting, for example, the length direction of hollow out item seam can be with It is parallel with the air inlet direction or vertical with the air inlet direction, it can also be in a certain angle with air inlet direction.It can also be simultaneously The hollow out item of multiple extending directions is set to stitch, so as to which heat exchange air-flow is made to pass through corrugated fin in different directions, is further increased The disturbance of heat exchange air-flow is added, the turbulence level of heat exchange air-flow has been improved, so as to improve the exchange capability of heat of corrugated fin.
Second fin part 12 can be changed with selected as corrugated structure, planar structure or plane hierarchic structure, corrugated structure Hot property is more preferable than planar structure, and the windage of planar structure is than corrugated structure smaller.
Specifically, ripple is highly preferred for 0.4-1.5mm, the highly preferred width stitched for 0.2-0.7mm, item of ladder Preferably 0.4-1.0mm.It is vertical thread hollow bar seam in the empty piece of ripple thread, the width of item seam is 0.4-0.8mm.
Preferably, fin body 1 is along the width in the air inlet direction for L, and first fin part 11 is along the air inlet side To width for L/3~L/2, by the width setting of the first fin part 11 range thus, it is ensured that the first fin part 11 place completely In fin body 1 close to the half region of windward side, this is also the main region that frosting occurs for fin, is thus prevented second Frosting in fin part 12.
Preferably, second fin part 12 is L/2~2L/3 along the width in the air inlet direction, by the second fin part 12 Width setting range thus, it is ensured that frost-free or only seldom frosting in the second fin part 12, and the second fin part 12 Shared width is more than the width shared by the first fin part 11, can further improve heat exchange property of the fin under nominal condition.
As shown in Figure 5 a, fin body 1 is equipped with the lantern ring 14 for wearing heat exchanger tube, can in order to improve heat exchange efficiency Designed using bias, i.e. the center of lantern ring 14 is not on the center line of 1 width of fin body, but by the center of lantern ring 14 to The leeward side Edge shifts setting of fin body 1, due to wind, temperature gradually rises when by heat exchanger, and will be in lantern ring 14 After the offset setting of leeward side, the Temperature Distribution on fin also gradually rises the heart approximately along the direction of transfer of wind, this is just and wind Temperature changing regularity is consistent, so as to reduce mean temperature difference, improves heat exchange efficiency.Optionally, lantern ring center can be supported or opposed Wind side deviates 1~6mm, i.e. the vertical range at lantern ring center and the center line of 1 width of fin body is 1~6mm.
