The production method of a kind of fin-tube type heat exchanger, as shown in Figures 2 to 4, comprises the steps:
S1, on heat exchanger tube 1, fixedly mount the first side plate 3 near end；
S2, on heat exchanger tube 1 sheathed many group fins 2, fin 2 offers the heat exchange pore 21 for plug-in mounting heat exchanger tube 1,
Being formed with flange 22 around heat exchange pore 21 on one side surface of fin 2, flange 22 is flange width along the axial width of heat exchanger tube
Degree；The biggest the closer to the flange width of its group inner fin of fins set of the first end；
S3, from the second end of heat exchanger tube 1 to the first end move swollen head exchange heat pipe 1 carry out tube expansion.
Compared to prior art, the production method of the fin-tube type heat exchanger that the embodiment of the present invention provides, this tube fin type heat exchange
In process of production, swollen head moves to the first end device from the second end of heat exchanger tube 1, so that the fin 2 being set on heat exchanger tube 1
Move to the first end, and owing to being installed with the first side plate 3 on the first end of heat exchanger tube, this makes to be set on heat exchanger tube and leans on
The fin of nearly first end is extruded, and the flange width of fin is extruded contraction, but due to the wing of the first end the closer to heat exchanger tube 1
The flange width of the fin 2 in sheet group is the biggest, namely the closer to adjacent two fins 2 in the fins set of the first end of heat exchanger tube 1

But qualification rate is the highest and tube expansion speed slow, inefficient.The qualification rate of hydraulic expanding tube mode is higher, tube expansion speed fast, efficiency
In height, but relatively costly, and swollen head, flowing is highly pressurised liquid, easily occurs accident during tube expansion failure.
Embodiment 1
The change of the flange width of the fin 2 being set on heat exchanger tube 1 is in units of fins set, namely in same fins set
The flange width of each fin identical, the biggest the closer to the flange width of the fin of heat exchanger tube the first end.The fin-tube type of this structure
The flange change width of the fin 2 on heat exchanger is in units of group, and this makes the flange width of each fin in same fins set
Identical, staff is the most error-prone when assembling, and the air-out gap distribution of the fin-tube type heat exchanger obtained after tube expansion is uniform.
When sheathed fin 2 on heat exchanger tube 1, can sheathed fin number is the most identical on heat exchanger tube 1 three groups of fins.Lean on
Number in the fins set of nearly first end is identical with the number in the fins set of the second end, near first when this makes tube expansion
The increments in the air-out gap in the total decrement produced when the fins set of end is compressed, with the fins set of close second end
Total amount size is essentially identical, so that it is guaranteed that this many group fins total length change on the axial direction of heat exchanger tube is little, it is to avoid
Overall dimensions change causes situation about cannot use to occur.
Specifically, in the above-mentioned three groups of fins being set on heat exchanger tube, as it is shown on figure 3,
Flange width near first group of fin of the first end of heat exchanger tube is h1, and h1=a+x, wherein, a is pipe wing
The standard air-out gap of formula heat exchanger, x is the flange width increments relative to standard air-out gap of first group of fin, a ∈
[0.995mm～1.9999mm], x ∈ [0.1mm～0.2mm]；The flange width of second group of fin of the second end of close heat exchanger tube
Degree is h2, and h2=a-y, wherein, y is the flange width decrement relative to described standard air-out gap of second group of fin,
Y ∈ [0.1mm～0.2mm]；The flange width of the 3rd group of fin between first group of fin and second group of fin is h3,
And h3=a.
Owing to the span of standard air-out gap a is between 0.995mm to 1.9999mm, this makes adjacent two panels fin
Between spacing less, even if first group of fin near the first end being produced extruding, on first group of fin during tube expansion
The space that flange can be extruded is the least, thus the flange width of first group of fin is relative to the increments in standard air-out gap
Unsuitable excessive, it is to avoid after tube expansion, the air-out gap of first group of fin is more than standard air-out gap.Flange width when first group of fin
When degree is less than 0.1mm relative to the value of increments x in standard air-out gap, the flange on first group of fin is extruded rear institute shape
The air-out gap become can be less than standard air-out gap, is easily caused the fin-tube type heat exchanger produced and uneven the showing of air-out occurs
As, meanwhile, when the value of x is less than 0.1mm, the production precision of fin is difficult to control, and product disqualification rate is too high.And when first
When the flange width of group fin is more than 0.2mm relative to the value of increments x in standard air-out gap, turning on first group of fin
While the air-out gap formed after being extruded can be more than standard air-out gap, also result in the fin-tube type heat exchanger produced and occur
The phenomenon that air-out is uneven.The second group of fin of close second end adjacent two panels wing during tube expansion, in second group of fin
Gap between sheet can increase, so that the air-out gap of second group of fin increases, but due to the compressible sky of first group of fin
Between little, thus the increased space in the air-out gap of second group of fin is little accordingly, thus the flange width of second group of fin
Can not be too much compared to the decrement in standard air-out gap, in order to avoid affecting the air-out of this fin-tube type heat exchanger.When second group of fin
Flange width relative to decrement y in standard air-out gap value less than 0.1mm time, adjacent two fins in second group of fin
Between air-out gap can be less than standard air-out gap, be easily caused the fin-tube type heat exchanger produced and occur that air-out is uneven
Phenomenon, meanwhile, when the value of y is less than 0.1mm, the production precision of fin is difficult to control, and conforming product rate is too low.And when second
When the flange width of group fin is more than 0.2mm relative to the value of decrement y in standard air-out gap, adjacent in second group of fin
Air-out gap between two fins can be more than standard air-out gap, also results in the fin-tube type heat exchanger produced and occurs that air-out is not
Uniform phenomenon.The 3rd group of fin being positioned at middle part will not be extruded during tube expansion, thus between the air-out of the 3rd group of fin
Gap will not change, and the 3rd group of fin uses the flange width fin equal to standard air-out gap, ensures that this pipe wing
The air-out uniformity of formula heat exchanger.
For guaranteeing that this fin-tube type heat exchanger its overall dimensions after tube expansion does not changes, the flange width of first group of fin
Relative to increments x in standard air-out gap, with the flange width of second group of fin relative to decrement y in standard air-out gap
Size identical.Now, total decrement that after tube expansion, first group of fin produces when being compressed, and between the air-out of second group of fin
The total amount size of the increments of gap is identical, and this three groups of fins total length on the axial direction of heat exchanger tube is constant, so that it is guaranteed that
The overall dimensions of this fin-tube type heat exchanger, does not interferes with the installation of this fin-tube type heat exchanger.
Preferably, the flange width of first group of fin is 0.1mm relative to increments x in standard air-out gap.When first
When the flange width of group fin is equal to 0.1mm relative to the increments in standard air-out gap, this fin-tube type heat exchanger after tube expansion
Overall air-out is the most uniform, does not also have the situation that sound of the wind is suddenly big or suddenly small, Consumer's Experience after noise minimum and long-time use
Higher.
Embodiment 2
From the point of view of tube expansion direction according to this fin-tube type heat exchanger, the extruded degree of fin the closer to the first end is the biggest,
Thus the flange width of any one group of fin being set on heat exchanger tube is set to the flange width of the fin the closer to the first end
Spend the biggest.The air-out gap distribution of the fin-tube type heat exchanger obtained after tube expansion is highly uniform, on the axial direction of heat exchanger tube, and should
The air-out of fin-tube type heat exchanger is the most identical.But the fin-tube type heat exchanger of this structure, the sheathed work of fin is relatively complicated, and
Owing to the flange width self of fin is less, variable quantity is trickle, and naked eyes cannot be differentiated, and this gives the production band of this fin-tube type heat exchanger
Carry out bigger difficulty.And the most tens of of the sum of sheathed fin on a heat exchanger tube, and the flange of these tens of fins
Width is the most different, and the difference of flange width is the trickleest so that the production fussy degree of fin and difficulty are the highest.
During for avoiding tube expansion, fin jumps, and causes the overall dimensions of this fin-tube type heat exchanger to change, such as Fig. 2 institute
Show, after being all set on heat exchanger tube 1 by all fins, then at the second end, fixedly mount the second side plate on heat exchanger tube 1
4, so that how group fin is respectively positioned between the first side plate 3 and the second side plate 4.Exchange heat pipe 1 after second side plate 4 is installed again and carry out swollen
Pipe, is clamped in during fin stress among two pieces of side plates, thus does not haves and jump, it is ensured that the profile of this fin-tube type heat exchanger
Size will not change, and does not haves the situation that overall dimensions change causes installing and using.
For reducing the technology difficulty during tube expansion, after the second side plate is fixedly connected on heat exchanger tube, can be by heat exchange
Second end of pipe makes heat exchanger tube uprightly place and fix upward.Second end of heat exchanger tube upward after, swollen head is from the second of heat exchanger tube
End enters inside heat exchanger tube, and the axial direction along heat exchanger tube moves exchange heat pipe tube expansion to the first end of heat exchanger tube, is set in and changes
Fin on heat pipe can be owing to the squeezing action produced when action of gravity and tube expansion be to the first end extruding of heat exchanger tube, so that overlapping
It is located at heat exchanger tube and produces extruding near the flange of the fin of end.
Embodiments of the invention also provide for a kind of fin-tube type heat exchanger, and this fin-tube type heat exchanger uses said method to make.
The fin-tube type heat exchanger that the production method using the embodiment of the present invention to provide produces, the air-out gap distribution between its fin is equal
Even, do not have, when air-out is uniform and uses, the situation that side sound of the wind big side sound of the wind is little.
The fin-tube type heat exchanger that embodiments of the invention are provided can be applicable in indoor apparatus of air conditioner, as it is shown in figure 5, air-conditioning
Indoor set includes cross flow fan 100, and the inlet air side of cross flow fan 100 is provided with fin-tube type heat exchanger 200 as above.Air-conditioning
After indoor set starts, cross flow fan 100 starts to rotate, and the air flowing near cross flow fan 100 forms air-flow and is admitted to indoor,
And owing to above-mentioned fin-tube type heat exchanger 200 is arranged on the inlet air side of cross flow fan 100, during air conditioner refrigerating, this fin-tube type heat exchanger is attached
When near cold air or air-conditioning heating, the hot-air near this fin-tube type heat exchanger is blown in indoor environment through cross flow fan 100,
Thus change indoor temperature.Owing to the air-out of this fin-tube type heat exchanger 200 is uniform, thus when cross flow fan 100 rotates, send into room
