Specific embodiment
Referring to Fig. 1 to 7,8 to 18, the heat exchanger 100 of embodiment according to the present invention includes: fin 1, and the fin 1 has
There is fin hole 11；And heat exchanger tube 2, the heat exchanger tube 2 are inserted into the fin hole 11 of the fin 1.Implementation according to the present invention
The heat exchanger tube 2 of example includes: main body 20, and when seeing in the mounted state, which has tubular form and there are two circumferential for tool
Upper opposite edge part 21, which includes: multiple sub- heat exchanger tubes 22, and connects the connector of adjacent sub- heat exchanger tube 22
29.Main body 20 has approximately C-shaped cross section.
Referring to Fig. 1 to 7,8 to 18, according to some embodiments of the present invention, when seeing in the mounted state, the multiple son is changed
Heat pipe 22 has generally arcuate outer surface.Thus it is matched with fin hole 11.In addition, the inner surface in fin hole 11 can be with
The outer surface of multiple sub- heat exchanger tubes 22 has complementary shape.The multiple sub- heat exchanger tube 22 can have any suitable shape
Outer surface.At least one of the multiple sub- heat exchanger tube 22 can have a hole or channel 23 or along the circumferential row of heat exchanger tube 2
The multiple holes or channel 23 of column.Thus, it is possible to flow through heat transferring medium.
Referring to Fig. 1 to 7,8 to 18, according to some embodiments of the present invention, the connector 29 is deformable, makes heat exchanger tube 2
It can be unfolded and close up.The connector 29 can be sheet shaped piece.
Referring to Fig. 1 to 7,8 to 18, according to some embodiments of the present invention, when seeing in the mounted state, on cross section,
The heat exchanger tube 2 has the substantially shape of part ring or C-shaped shape, for example, the shape of substantially partial circle, i.e., annulus, it is right
It should be less than the shape of the part of 360 degree of central angle.The inner peripheral surface and outer peripheral surface of heat exchanger tube 2 can for it is substantially arc-shaped can also be with
It is non-radiused.
In addition, heat exchanger tube is round tube in above-described embodiment, however to be also possible to elliptical tube etc. other transversal for heat exchanger tube
The pipe in face, thus the section of the sub- heat exchanger tube 22 also correspondingly changes.
As illustrated in fig. 1 and 2, the original state processed of heat exchanger tube can be state shown in Fig. 1 and 2.Then it is closed
Hold together, as shown in Fig. 3,4,13,14,15.Referring to Figure 16,17,18, needed after fin hole to be penetrated by its expanded joint and realization and wing
The complete fitting of piece inner hole, the expanded joint mode for then needing one kind relatively reasonable is to realize the function.
Referring to Fig. 1 to 18, especially Figure 10,11,12, the assemble method of the heat exchanger 100 of embodiment according to the present invention,
It include: that multiple fins 1 are provided, each fin 1 has fin hole 11；Heat exchanger tube 2 is inserted into fin hole 11, the heat exchanger tube
2 include: main body 20, which has circumferential opposite edge part 21 there are two tubular form and tools；And it is formed in
Hole in the main body 20；Insertion piece 30 is inserted into the hole in the main body 20, and insertion piece 30 is made to be directed at the two of main body 20
Opening in a circumferential direction between opposite edge part 21；And the swollen head 60 being connect using the movement of moving member 50 with moving member 50,
Make swollen head 60 from one end of heat exchanger tube 2 enter the main body 20 in hole in and from the other end from the hole in the main body 20 quilt
It removes, thus swollen head 60 is squeezed into insertion piece 30 in the opening between edge part 21 opposite in two circumferential directions of main body 20.It moves
Moving part 50 can be traction piece, and swollen head 60 or moving member 50 is thus pulled to can be impeller, thus push swollen head 60.?
In the embodiment of diagram, moving member 50 is the bar as traction piece.
Specifically, heat exchanger tube penetrates in the state of fin hole referring to Figure 13 to 15, heat exchanger tube closes up.From heat exchange
One end of pipe penetrates insertion piece and moving member.Moving member can expose and can be held from the other end of heat exchanger tube.Insertion piece
Effect be opposite edge part in two circumferential directions that insertion piece is squeezed into main body when swollen head passes through the hole in heat exchanger tube
Between opening in, to have the function that permanent support.In addition to insertion piece shown in figure, the section of insertion piece be can also be
Rectangle, parallelogram, polygon, it is trapezoidal etc..
As shown in Figure 10,11, the swollen head 60 has frustoconical portion 61, the cross section of the frustoconical portion 61
It is gradually increased from 50 1 side of moving member to the other side.The swollen head 60 can also have to be located at what frustoconical portion 61 was connect
The stylolitic part 62 of the other side of frustoconical portion 61, cross section and column of the frustoconical portion 61 in the other side
The cross section of shape part 62 is roughly the same.The frustoconical portion 61 of the swollen head 60 can be frusto-conically shaped portion.Swollen head
60 shape can require to be selected according to the shape and technique in the hole of the main body 20 of heat exchanger tube 2, and be not limited to above-mentioned shape
Shape.According to another embodiment of the invention, the swollen head 60 has approximately spherical shape.As described above, the moving member
50 be bar.Alternatively, moving member 50 can be rope etc..In addition, swollen head 60 is also possible to cylinder.For the ease of pulling
Swollen head 60, swollen head 60 have chamfering or fillet in 50 side of moving member.
Referring to Figure 16 to 18, after expanded joint, swollen head is pulled away, and insertion piece is left permanently in opposite in two circumferential directions
Edge part between opening in, formed support, with ensure exchange heat pipe outer wall and fin inner hole wall surface permanent contact.
Referring to Figure 10,11,12, insertion piece 30 is being inserted into the hole in the main body 20, and is making the alignment master of insertion piece 30
After opening in two circumferential directions of body 20 between opposite edge part 21, moving member 50 is inserted into institute from one end of heat exchanger tube 2
It states in the hole in main body 20 and exposes moving member 50 from the hole in the main body 20 in the other end.Pass through mobile moving member
50, insertion piece 30 is squeezed into the opening between edge part 21 opposite in two circumferential directions of main body 20 by swollen head 60.
As shown in Fig. 8,9,10,11,12, example according to the present invention, insertion piece 30 is towards the side outside heat exchanger tube 2
With insertion piece conical section 31, the width of insertion piece conical section 31 gradually becomes smaller on the direction towards outside heat exchanger tube 2.
Be conducive to swollen head 60 as a result, to squeeze into insertion piece 30 in the opening between edge part 21 opposite in two circumferential directions of main body 20.
When watching on cross section, at least part of insertion piece 30 on the surface towards the side inside heat exchanger tube 2 has arc
Profile 32.Alternatively, at least part of insertion piece 30 on the surface towards the side inside heat exchanger tube 2 has linear
Profile.Example according to the present invention, insertion piece 30 have those widened sections 33, the those widened sections 33 towards the side inside heat exchanger tube 2
Width be greater than edge part 21 opposite in two circumferential directions that insertion piece 30 squeezes into main body 20 between opening in after two
The width of opening in a circumferential direction between opposite edge part 21.
The assemble method of the heat exchanger of embodiment according to the present invention is solved for fine or small internal diameter heat exchanger tube and wing
The expanded joint or assembly problem of piece；Reduce swollen bring heat exchanger tube risk of rupture in conventional heat transfer pipe；And it can be with better simply
Method realizes the expanded joint between heat exchanger tube and heat exchange fin.
The assemble method of the heat exchanger of embodiment according to the present invention, can or elastic deformation indeformable in heat exchanger tube
