Abstract

The invention discloses a method for manufacturing cooling fins, comprises the following steps of: (1) fixing a base on a lower die holder of a punching machine; (2) providing a group of cooling fins which are uniformly distributed and fixed on an upper die holder of the punching machine; (3) starting the punching machine and pressing the cooling fins in the base; and (4) smoothing a lower bottom surface of the base. The method has a simple and practical processing step; the cooling fins are fastened on the base in a stamping manner to ensure that the cooling fins and the base are fully attached and connected; and therefore, the obtained product has a stable structure and has no gap, the heat conduction is sufficient and the heat dissipation effect is greatly increased.

Description

A kind of manufacture method of fin

Technical field

The present invention relates to a kind of manufacture method of fin, particularly a kind of simple in structure, firm, the manufacture method of the fin that radiating effect is good.

Background technology

Continuous development along with science and technology, constantly weed out the old and bring forth the new at field new products such as computer, machine-building, usually need to use fin on these products, present fin mainly comprises pedestal and radiating fin, welding, the mode that connects of clamping and viscose of adopting commonly used.

Mode by welding links together radiating fin and pedestal and has increased the weight of fin, often has the gap between pedestal and the radiating fin, influences heat conductivility;

Adopting the mode of clamping, is that the upper surface at pedestal is provided with several slots, and radiating fin inserts slot, and with the mutual clamping of slot, adopt this mode, the same gap that easily produces between pedestal and the radiating fin, influence the heat transmission of radiating fin and frame piece, caused radiating effect not good;

Have the gap between pedestal and radiating fin, the mode that can also make radiating fin pass through viscose is fixedlyed connected with pedestal, and both are unlikely to produce the gap in conjunction with comparatively tight; Though solved aforesaid problem by the method,, the gluing mode that connects can not make pedestal combine with radiating fin firmly, and the heat radiating fin sector-meeting comes off from pedestal, and in addition, the viscose heat-conducting effect is poor, can produce certain influence to radiating effect.

Summary of the invention

Goal of the invention: the objective of the invention is in order to overcome the deficiency of existing product technology, provide a kind of simple in structure, firm, the manufacture method of the fin that radiating effect is good.

Technical scheme: in order solving the problems of the technologies described above, to the invention provides a kind of manufacture method of fin, to may further comprise the steps:

(1), pedestal is fixed on the stamping machine die shoe;

(2), provide one group of radiating fin, described radiating fin evenly to arrange and be fixed on the stamping machine upper bolster;

(3), start stamping machine, radiating fin is pressed in the pedestal;

(4), smooth pedestal bottom surface.

Beneficial effect: compared with prior art, the manufacture method of a kind of fin provided by the invention has following advantage: this processing step is simple, practical, and the radiating fin of products obtained therefrom is fastened on the pedestal by impact style, both abundant fastening applyings, its structure is firm, there is not the gap in the junction, has improved heat conductivility, has improved radiating effect greatly.

Description of drawings

Fig. 1 is a process chart of the present invention;

The product structure schematic diagram of Fig. 2 for adopting this technology to make.

The specific embodiment

The present invention is described in further detail below in conjunction with drawings and Examples, should understand these embodiment and only be used to the present invention is described and be not used in and limit the scope of the invention.

As shown in Figure 1, this method comprises:

(1), a pedestal 1 is provided, be fixed on the stamping machine die shoe;

(2), provide one group of radiating fin, described radiating fin 2 evenly to arrange and be fixed on the stamping machine upper bolster; Be provided with spacing between adjacent radiating fin 2, form the heat dissipation channel for air flow channel, this spacing range is 3mm ~ 6mm, and every radiating fin 2 thickness ranges are 5mm ~ 20mm, and altitude range is 30mm ~ 250mm,

(3), start stamping machine, radiating fin 2 inserts pedestal 1 by impact style and is fastenedly connected with it;

(4), smooth pedestal bottom surface; Because through punching press, pedestal 1 can occur depressed part and protuberance respectively with radiating fin 2 contact position upper surfaces and pedestal 1 bottom surface, and wherein protuberance can be removed by impact style or polishing mode, to keep the flatness of bottom surface, pedestal 1 and thermal source are fitted tightly, enlarge area of dissipation.

As shown in Figure 2, the pedestal 1 of this fin and radiating fin 2 adopt the good aluminum alloy materials of heat conductivility to make, and have good performance of heat dissipation; Simultaneously because aluminum alloy materials has good toughness, the mode of radiating fin 2 by punching press can with pedestal 1 good fastening applying, avoided both generation spaces, junctions, thereby further improved the capacity of heat transmission.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
