CN202050631U - Radiating slice - Google Patents

Abstract

The utility model discloses a radiating slice which comprises a base and a group of radiating fins. The radiating fins are inserted into the base through a stamping way and are firmly connected with the base; the scope of the space between the adjacent radiating fins is 3 mm to 6 mm; and the thickness of each radiating fin is in the scope of 5 mm and 20 mm, and the height of each radiating fin is in the scope of 30 mm and 250 mm. In the radiating slice, the base is firmly connected with the radiating fin by the radiating slice through the stamping way. The radiating slice has a simple structure, is connected stably and fully adhered and has no clearance, sufficient heat conduction and obvious radiating effect. The base and the radiating fins are made of aluminum alloys with excellent heat conducting property, thereby greatly improving the heat dispersion.

Description

A kind of fin

Technical field

The utility model relates to a kind of fin.

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.

The utility model content

The utility model purpose: the purpose of this utility model is in order to overcome the deficiency of existing product technology, to provide a kind of simple in structure, firm, the fin of good heat dissipation effect.

Technical scheme: in order to solve the problems of the technologies described above, the fin that the utility model provides comprises pedestal and one group of radiating fin, radiating fin inserts pedestal by impact style and is fastenedly connected with it, spacing range is 3mm ~ 6mm between the adjacent radiating fin, every radiating fin thickness range is 5mm ~ 20mm, and altitude range is 30mm ~ 250mm.

Described pedestal and radiating fin adopt aluminum alloy materials to make.

Beneficial effect: compared with prior art, the fin that the utility model provides has following advantage:

1, radiating fin inserts pedestal by impact style and is fastenedly connected with it, and it is simple in structure and firm;

2, pedestal and radiating fin fully are fitted and connected, and do not have the gap, and heat conduction is abundant, and radiating effect is obvious;

3, pedestal and radiating fin adopt the good aluminium alloy of heat conductivility to make, and have improved heat dispersion greatly.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

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

As shown in Figure 1, described fin comprises a pedestal 1 and one group of radiating fin 2, and described pedestal 1 and radiating fin 2 adopt the good aluminum alloy materials of heat conductivility to make, and radiating fin 2 inserts pedestal 1 by impact style and is fastenedly connected with it; 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.

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, and is higher than existing fin heat dispersion.

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

Claims (2)

1. fin, comprise pedestal (1) and one group of radiating fin (2), it is characterized in that: radiating fin (2) inserts pedestal (1) by impact style and is fastenedly connected with it, spacing range is 3mm ~ 6mm between the adjacent radiating fin (2), every radiating fin (2) thickness range is 5mm ~ 20mm, and altitude range is 30mm ~ 250mm.

2. a kind of fin according to claim 1 is characterized in that: described pedestal (1) and radiating fin (2) adopt aluminum alloy materials to make.
