Description
[technical field]
The utility model is about a kind of radiator, and particularly a kind of have than big area of dissipation and the firm stacking fin type radiator of structure.
[background technology]
Be accompanied by the constantly development of electronic information industry, electronic component (particularly CPU) running frequency is also in continuous lifting.But because the high-frequency high-speed operation makes that the heat that electronic component produced is more and more many, temperature is difficult in time distribute, caused electronic component and ambient temperature constantly to raise, the performance of normal operation of electronic component and performance thereof in serious threat, for guaranteeing that electronic component can normal operation, in time the discharge heat that electronic component produced.For this reason, industry is fitted on the electronical elements surface with heat abstractor usually, dispels the heat, and temperature is controlled in the temperature range that electronic component can normally move.
Be United States Patent (USP) the 4th as shown in Figure 1,884, No. 331 disclosed radiators 10, this radiator 10 are the quite common types of industry, via aluminium extruded, cut, after a series of processed such as profile groove, flash removal, sand milling, polishing, anode treatment, can obtain final structure kenel.Though easily manufactured, production capacity is high, the waste material that the profile groove program of this radiator is produced accounts for the integral material quite great proportion, therefore, for considering of cost, obviously is not ideal designs.In addition, because the restriction on mould strength and the correlation technique level, the ratio of groove width d is limited between the fin height h of this radiator 10 and fin, its h/d ratio reaches 13: 1 at the most approximately, make the cooling surface area of entire radiator 10 be very restricted, the radiating requirements in the time of can't satisfying the work of present central processing unit.
As shown in Figure 2, other has the dealer is the depth-width ratio value h/d that increases radiating fin, adopts the some radiating fins 32 mutual snappings that are Contraband type cross section to link and composition radiator 30 increases area of dissipation.Be equipped with shrinkage pool 36 on these radiating fin 32 upper and lower side flangings 34, extend to form a lug 38 in shrinkage pool 36 leading edges, this lug 38 further dashes and is provided with salient point 39.The winding of above-mentioned radiating fin 32 is that the lug 38 by a radiating fin 32 is plugged in the shrinkage pool 36 of an adjacent radiating fin 32, but its salient point 39 blocks on the plate body of radiating fin 32, thereby in conjunction with forming an integral heat sink device 30.Though processing such as this radiator can an integral body be electroplated, welding, but the combination of radiating fin 32 owes firmly, and when imposing opposition simultaneously, the salient point 39 of lug 38 very easily breaks away from shrinkage pool 36, radiating fin 32 is dismembered separation thereupon, makes entire radiator 30 lose efficacy.
[summary of the invention]
But the purpose of this utility model is to provide a kind of has big area of dissipation efficiently radiates heat, and makes up solid and reliable stacking fin type radiator.
Stacking fin type radiator of the present utility model, be to fasten mutually by a plurality of radiating fin monolithics to form, first flanging that each radiating fin has a heat radiator body and is provided with in above-mentioned heat radiator body two ends, second flanging, the contiguous above-mentioned first flanging place of above-mentioned heat radiator body is provided with the reverse tongue piece of at least one and above-mentioned first flanging, above-mentioned first flanging and tongue piece are provided with at least one fastening structure, and the contiguous above-mentioned second flanging place of above-mentioned heat radiator body is provided with the reverse catching groove of at least one and above-mentioned second flanging, and above-mentioned second flanging is provided with at least one cramp that is inserted in the adjacent radiating fin catching groove.
The utility model radiator adopts the radiating fin of a plurality of separation to combine, and has the big advantage of area of dissipation; Simultaneously, radiating fin is to be inserted in the catching groove of adjacent radiating fin by cramp, realizes connecting, and therefore two radiating fins are difficult for breaking away from inefficacy because of imposing opposition, has the solid and reliable advantage of combination.
With reference to the accompanying drawings, the utility model will be further described in conjunction with the embodiments.
