Abstract

The utility model relates to a heat radiating fin assembly structure, the end edges of both sides of a fin protrude outwards and are provided with buckle parts which can be bent inwards in a same direction, each buckle part extends to form in sequence a neck part and a groove which is arranged in the tail end of each neck part in a cut mode, an upper and a lower folded feet which are oppositely bent inwards are protruded on the two side end surfaces of each neck part close to the groove, and a buckle groove which is used for buckling with the side edge of another fin sheet is formed between the upper and the lower folded feet. When a plurality of the fins are buckled and assembled one by one, the folded feet at both sides of the buckle parts of one fin are buckled with the surface and the bottom surface of another fin sheet, meanwhile, with the help of the grooves of the buckle parts of the one fin to be buckled, abutted and limited with the neck part of the buckle part of the another fin, and the buckle parts at both sides of the one fin to be buckled and limited with the buckle parts at both sides of another fin, thus the fins are positioned stably and the displacement shake in up and down, front and back and right and left directions is reduced, and the effects of stable buckle joint and tight fit between the fins are obtained.

Description

The radiating fin package assembly

Technical field

The utility model particularly relates to the radiating fin package assembly of the heat abstractor of electronic product euthermic chip for a kind of radiating fin package assembly is provided.

Background technology

Scientific and technological now information fast development, and individual desktop computer and notebook computer are because calculation function is strong, speed is fast, therefore by widespread in industry-by-industry, and the arriving in networking epoch more causes the universalness of computer, wherein the chip in the computer can produce heat energy when running, and the fast more heat energy that produces of speed is high more, for avoiding Yin Gaore to burn chip, and the useful life of shortening chip, therefore fin all is set on each chip, make the thermal energy conduction that produces on the chip to fin, dispel the heat to the surface gap of fin with the blow cold air that fan was produced again, yet, allow heat dissipation better, just must allow the fin number of fin increase or increase the rotating speed of fan; But, the necessary attenuation of thickness of fin if the fin increase then is bound to, and thin excessively fin can take place and cause welding difficult or weld the crooked situation of back fin because location difficulty and gap are too small or yielding when being welded in base; Be with, promptly there is the fin of combined radiating fin to produce, see also Fig. 7, shown in Figure 8, be that " composite type heat radiation fin structure " novel patent is announced in Taiwan No. 365411, for applying for December 24 2007 Christian era, application case number No. 86221373, and announce in shown in the patent gazette in July 21 1999 Christian era, this fin A is formed by a plurality of fin A1 group structures, wherein this a plurality of fin A1 bottom all has a joint portion A11, and but each joint portion A11 is provided with the protuberance A111 of other fin of inlay card A1 recess A112, and the assembling that cooperatively interacts by this makes a plurality of fin A1 be able to secure bond to be groups of fins, to install on the chip of paramount heat again; But this kind mode still has a little shortcoming, when a plurality of fin A1 desire to be positioned to dispel the heat on the chip in the host computer, the mutual anchor point of joint portion A11 of its a plurality of fin A1, only utilize the contact end face of protuberance A111 and recess A112 to support mutually, spacing, the position-limiting action of its protuberance A111 and recess A112 shows slightly thin, the upper and lower position-limiting action only is provided, in direction all around and can't effectively support buckle, when mobile a plurality of fin A1 to chip fixedly the time, a plurality of fin A1 are produced to be rocked, it is big that gap between fin A1 becomes, and has fin A1 to get loose, radiating efficiency reduces, the problem of deriving of precise structure degree difference.

In summary, the above-mentioned shortcoming of prior art, just for to be engaged in the problem of this journey improvement that the dealer desires most ardently, and the dealer that remains to be correlated with makes further improvement and the necessity that redesigns.

Summary of the invention

Modern, because the shortcoming of above-mentioned prior art, so the inventor utilizes the research and development experience for many years of engaging in the industry, via studying and revising, design finally that this kind fastening is firm, closely cooperate between each fin Du Gao and reduce about, all around direction displacement radiating fin package assembly of rocking novel.

Radiating fin package assembly of the present utility model, it stacks the package assembly of snapping for a plurality of fins, be that fin both sides ora terminalis is convexly equipped with outwardly in respect of the clamping part that can bend inwards together, and each clamping part is extended with neck in regular turn and neck finish is cutd open the groove of establishing, and neck is provided with the relatively inwardly pin of folding up and down of bending near groove both sides end face epirelief, and is formed with the buckling groove that fastens another fin sheet material lateral margin between pin in rolling over up and down.

When a plurality of fins fasten assembling in succession, fin clamping part both sides folding pin can be detained to another fin plate surface and bottom surface, the groove that is aided with the fin clamping part simultaneously supports spacing with engaging of the neck of another fin clamping part, and fin both sides clamping part fastens the effect that limits another fin both sides clamping part, about can making each fin strong fix, reducing, all around direction displacement problem of rocking, reach and fasten the high effect of degree of closely cooperating between firm, a plurality of fins.
