The utility model is to overcome defect in above-mentioned prior art, provides a kind of and welds more evenly with heat exchanger tube, the fin of heat exchanger easily, improves a kind of heat exchanger with this fin simultaneously.
For achieving the above object, the utility model provides a kind of fin of heat exchanger, comprises plate body, described plate body is provided with multiple pore for installing heat exchanger tube, the edge of described pore is provided with a fabrication hole be conducted with it, and the size of described fabrication hole is greater than the diameter of welding rod.
By above-mentioned setting, by welding rod insertion process hole, after welding rod constantly melts, solution moves around the surface current of pore, and when pore local deformation or scale error, solution can be walked around easily and cover remaining pore face, guarantees overall welding quality.
Be set to further: the outer rim of described pore is provided with flange.
Be set to further: the corresponding described fabrication hole place of described flange is provided with otch, and the width of described otch is greater than diameter or the width of fabrication hole.
Be set to further: a kind of heat exchanger, comprising:
Fin, this fin comprises plate body, described plate body is provided with multiple pore for installing heat exchanger tube, and the edge of described pore is provided with a fabrication hole be conducted with it, and the size of described fabrication hole is greater than the diameter of welding rod.

Detailed description of the invention
Below in conjunction with accompanying drawing, a detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
In Fig. 2 and Fig. 3, finger direction is the flow direction of solution after welding rod 4 melting.
A kind of fin 1 of the utility model as shown in Figure 4 and Figure 5, comprise plate body 11, plate body 11 is evenly provided with multiple row pore 12, this pore 12 is preferably oval, also can be that circle waits other shapes, the bore of pore 12 slightly larger than the bore of heat exchanger tube 2, thus is convenient to heat exchanger tube 2 to install in pore 12; The edge of pore 12 is provided with a fabrication hole 3, this fabrication hole 3 is connected with pore 12, the size of fabrication hole 3 is greater than the diameter of welding rod 4, by in welding rod 4 insertion process hole 3, after welding rod 4 constantly melts, solution moves around the surface current of pore 12, when pore 12 local deformation or scale error, solution can be walked around easily and cover remaining pore 12, guarantees overall welding quality, makes fin 1 be connected more reliable and stable with heat exchanger tube 2.
Further setting, the outer rim of pore 12 is provided with flange 4, effectively can increase the contact area between pore 12 and heat exchanger tube 2 by the setting of flange 4, thus improves the connective stability of heat exchanger tube 2 and plate body 11.
Further setting, corresponding described fabrication hole 3 place of flange 4 is provided with otch 15, the width of otch 15 is greater than diameter or the width of fabrication hole 3, the height of flange 4 not only effectively can be increased by the setting of otch 15, prevent cracking during punching flange 4, increase the contact area between pore 12 and heat exchanger tube 2 further, improve connection reliability, facilitate welding rod 4 insertion process hole 3 simultaneously, avoid the interference of flange 4.
As shown in Figure 1 to Figure 3, heat exchanger comprises fin 1 and heat exchanger tube 2, fin 1 has polylith to be uniform intervals arrangement, between adjacent fins 1, flange 4 abuts, namely the flange 4 of the pore 12 of first piece of fin 1 is connected on the plate body 11 plate face of second piece of fin 1, the flange 4 of the pore 12 of second piece of fin 1 is connected on the plate body 11 plate face of the 3rd piece of fin 1, thus formation is intervally arranged, and the spacing between adjacent two pieces of fins 1 is by the Altitude control of flange 4; Heat exchanger tube 2 is set in pore 12, and the inwall of the flange 4 of pore 12 abuts with the lateral wall of heat exchanger tube 2, by welding or other modes, heat exchanger tube 2 is linked together reliably with the plate body 11 of fin 1; Every block fin 1 is provided with fabrication hole 3, the position of the fabrication hole 3 that every block fin 1 is arranged is arranged in corresponding, the circle centre position of same row fabrication hole 3 forms a passage 3 plugged for welding rod 4 on the same axis, insert in this passage 3 by welding rod 4, after welding rod 4 constantly melts, solution moves, when pore 12 local deformation or scale error around the surface current of respective pore 12, solution can be walked around easily and cover remaining pore 12, ensure that overall welding quality.
