The utility model technical solution problem, can also take following measure:
A kind of execution mode of the present utility model is: can be provided with the projection that the afterbody that makes fin scatters near the laminated section office between adjacent two fins.
Another kind of execution mode of the present utility model is: described projection can be shaped when the chimb that the fin surface punching forms.
Another kind of execution mode of the present utility model is: described projection forms in the time of can folding flange outside fin.
Another kind of execution mode of the present utility model is: described device for fastening can be made of two metal briquettings and bolt, two metal briquettings are positioned at the both sides of fin laminated portions, bolt passes the laminated portions of two briquettings and fin, and it is smooth that the external face of fin laminated portions has one side at least.
Another kind of execution mode of the present utility model is: described laminated section can be located at the head of each fin, and the afterbody of fin scatters and is fan shape.
Another kind of execution mode of the present utility model is: described laminated section can be located at the centre of each fin, and two afterbodys of fin scatter respectively and are two fan-shaped merging bodies.
Another kind of execution mode of the present utility model is: the external face of described each fin laminated portions has at least one side to connect or is pasted with a metal derby.
Another kind of execution mode of the present utility model is: the external face of described each fin laminated portions has at least one side to connect or is pasted with a metal derby.
Another kind of execution mode of the present utility model is: the afterbody of described each fin is provided with tip-tilted tail fin.
The utlity model has following outstanding effect:
1, the utility model is made of fastener and discrete fin, and manufacture craft is simple, and the identical production of the shape of each fin is easy, and technology was simple when each fin was assembled together, and manufacturing cost is low.Be specially adapted to the heat radiation of semiconductor refrigerating assembly.
2, the utility model since the afterbody of fin disperse, diverge to fan-shaped or similar discoid, during application, can increase air to flow area, be beneficial to the quickening speed air flow, make cross-ventilation more smooth and easy, improve the radiating efficiency of radiator.

Embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Specific embodiment 1:
With reference to Fig. 1, present embodiment is made up of device for fastening and number of metal fin 1.Described fin 1 leaves a laminated section at its root, and laminated section is provided with installing hole, and each fin 1 is being provided with projection 3 near the laminated section place.As Fig. 2, shown in Figure 3, projection 3 is formed by formed chimb 4 when the fin surface punching, is perhaps formed by the flange 5 that is folded outside fin 1.Each fin 1 is laminated in together at the laminated section place.Device for fastening is made of two metal briquettings 8, and two metal briquettings 8 clip the laminated portions 2 of fin 1.The installing hole that two bolts 9 pass each fin tightens up two briquettings each fin 1 is tightened up together.Because projection 3 is near the laminated sections of fins, and when assembling, be positioned at 1 of two fin,, make between adjacent two fins and form certain included angle so this projection 3 will be separated two adjacent fins, thus the afterbody of some fins 1 scatter be one fan-shaped.
During application, radiator fan is installed on the sector, the gap between radiator fan and fin over against.Radiator fan when running, thereby the gap process of air fin, and heat on the fin taken away.This kind radiator air big to flow area, and air flows is smooth and easy, and the radiating efficiency of radiator is improved greatly.
Specific embodiment 2:
The characteristics of present embodiment are: Fig. 4, Fig. 5, shown in Figure 6, and the laminated section of fin 1 is located at the centre of each fin 1, and the both sides of laminated section are respectively equipped with projection 3.The both sides afterbody of each fin is provided with tail fin 7, and tail fin 7 is tilted upward.Device for fastening tightens up each fin 1 in the centre, two afterbodys of some fins 1 scatter under projection 3 effect respectively, and its shape is fan-shaped in the center of circle and the merging body that closes as two.The laminated section office has one side to connect or is pasted with a metal derby 6.In the time of in being applied in refrigerating chip, 6 one faces of metal derby contact with chip.Because the refrigerating chip surface area ratio is bigger, radiator contacts with chip by metal derby 6 again, can avoid the problem that the space left between laminated portions 2 place's fins can not airtight chip.
