As shown in Figures 2 to 4, this fin 20 includes：Fin main body 21, be formed in fin main body 21, change for setting
The fin hole 22 of heat pipe 10, and the fin hole flanging of the annular extending to the side of fin main body 21 from the edge of fin hole 22
23.Heat exchanger 100 also includes welding material, for the fin hole flanging 23 of fin main body 21 is welded on one with heat exchanger tube 10
Rise.
As shown in Figures 2 to 4, in some examples of the present invention, the size of the fin hole flanging 23 of fin main body 21 before assembling
Less than the size of described heat exchanger tube 10, thus make the fin hole flanging 23 of fin main body 21 and described heat exchanger tube 10 shape after assembling
Become interference fit.Described fin main body 21 can also include：It is formed at the otch in fin hole flanging 23.
As it can be seen in figures 5 and 6, described welding material is formed as ring-shaped article 30, and it is arranged on described heat exchanger tube 10 and fin
Between the fin hole flanging 23 of main body 21, the fin hole flanging 23 of fin main body 21 and heat exchanger tube 10 to be welded on by heating
Together.As the highly heat-conductive material that welding ring can be that fusing point is less than fin and heat exchanger tube, after heating, welding ring melts ring-shaped article 30
Change and fin and heat exchanger tube are welded together.
Alternatively, as it can be seen in figures 5 and 6, heat exchanger 100 also includes：Ring-shaped article 30, this ring-shaped article 30 be arranged on described in change
Between the fin hole flanging 23 of heat pipe 10 and fin main body 21, and the inner surface of ring-shaped article 30 and outer surface all carry work
Welding composite bed for welding material.Ring-shaped article 30 can be the alloy as fin and heat exchanger tube.
As it can be seen in figures 5 and 6, the outer surface of ring-shaped article 30 is taper surface, and the fin hole flanging 23 of fin main body 21
Inner surface is taper surface.The taper of the fin hole flanging 23 of the taper surface of ring-shaped article 30 and fin main body 21, towards cooperation, makes ring
The taper surface of shape part 30 is fixed on the taper surface of fin hole flanging 23 of fin main body 21.
The manufacture method of heat exchanger according to an embodiment of the invention is described below.
Referring to Fig. 1 to 4, the manufacture method of this heat exchanger includes：Heat exchanger tube 10 is provided；And form fin 20, this fin
20 include：Fin main body 21, is formed in the fin main body 21, fin hole 22 for arranging heat exchanger tube 10, and from fin
The fin hole flanging 23 of the annular that the edge in hole 22 extends to the side of fin main body 21.The manufacture method of this heat exchanger is also wrapped
Include：By putting into heat exchanger tube 10 in fin hole 22, heat exchanger tube 10 is fitted together with fin 20；And using welding material
The fin hole flanging 23 of fin main body 21 and heat exchanger tube 10 are welded together by material.
According to the example of the present invention, before assembling, the fin hole flanging 23 of fin main body 21 is smaller in size than described heat exchanger tube 10
Size, make the fin hole flanging 23 of fin main body 21 and described heat exchanger tube 10 form interference fit.By heat exchanger tube is put
Before the step entering fin hole and heat exchanger tube and fin being fitted together, the inner surface of fin hole flanging or heat exchanger tube appearance
Face carries the welding composite bed as welding material.That is, fin or heat exchanger tube surface welding composite bed, fin hole size is little
In heat exchanger tube diameter, during installation, heat exchanger tube force draw in fin hole, on fin hole flanging can with otch with allow fin hole and
Fin hole flanging 23 stretches.Assembling completes to be welded.
Before heat exchanger tube 10 and fin 20 being fitted together by heat exchanger tube 10 is put into fin hole 22, heat exchanger tube 10
Upper precoating soldering paste.That is, fin and heat exchange pipe surface all welding composite beds, before assembling, heat exchanger tube precoats soldering paste, then fills
Join and complete to be welded.
According to the example of the present invention, described welding material is formed as ring-shaped article 30, and is arranged on described heat exchanger tube 10 He
Between the fin hole flanging 23 of fin main body 21, the fin hole flanging 23 of fin main body 21 and heat exchanger tube 10 to be welded by heating
It is connected together.Alternatively, by heat exchanger tube 10 is put into fin hole 22, heat exchanger tube 10 is being fitted together with fin 20
Step in, ring-shaped article 30 is placed between the fin hole flanging 23 of annular of described heat exchanger tube 10 and fin main body 21, and ring
The inner surface of shape part 30 and outer surface all carry the welding composite bed as welding material.
Using the technical scheme in embodiments of the invention, it is possible to achieve the manufacture of small-pipe diameter heat exchanger, solve pipe with small pipe diameter
(for example, ＜ 7mm) heat exchanger cannot tube processing technical barrier.Heat exchanger can be made to have higher heat exchange property and lower
Cost.
The heat exchanger of big pipe (for example, diameter ＞ 7mm) at present, adopts tube technology mostly, and this is compared with direct welding
If, the thermal contact resistance that tube connects can be more than welding, so heat exchange property is not so good as weld connection.
Using the connected mode of the fin in embodiments of the invention and heat exchanger tube, the heat-exchange performance of soldering can not only be ensured
Can, but also manufacture pipe with small pipe diameter (for example, ＜ 7mm) heat exchanger, because current tube expansion technique can be used only in caliber and is more than for example
On the heat exchanger of 7mm.
Using the technical scheme in embodiments of the invention, current pipe with small pipe diameter (for example, ＜ 7mm) heat exchange not only can be solved
Device cannot tube expansion and the problem that cannot produce, simultaneously as fin and heat exchanger tube adopt solder technology, there is extraordinary heat transfer
Performance.
Using the technical scheme in embodiments of the invention, employ ring-shaped article 30, between due to fin hole and heat exchanger tube being
Gap coordinates, and such heat exchanger tube can inject fin hole very wellly, substantially reduce technology difficulty and cost, improve product
Quality.
It should be noted that all technical characteristic in the above embodiment of the present invention or some technical characteristics can be to appoint
What suitable mode is combined and forms new embodiment.
