The radiating fin is composed of a plurality of metal plate pieces in a definite size, wherein the edge of each of the plate pieces forms a flanging on which a tenon joint mechanism is arranged and the main bodies of the plate pieces are continuously tenoned and connected in series by the tenon joint mechanisms to form the radiation fin. the radiation fin has the advantages of convenient assembly, assembly time saving, high aspect ratio, high-density heat radiating area and easy assembly. The utility model can be produced with large quantity.

Description

A kind of groups of fins assembling structure improves

The utility model relates to a kind of groups of fins assembling structure, refers to especially a kind ofly have high aspect ratio (aspect ratio) and high density area of dissipation, and can be suitable for the groups of fins assembling structure producing in a large number and be easy to assemble.

Because the quick upgrading of computer industry, make the running speed of electronic building brick increase day by day, and the heat that it produced also increases thereupon, therefore, can under its permissive temperature, continue action for keeping electronic building brick, be additional on the electronic building brick surface to have the larger area fin, make it can increase heat-sinking capability.

Yet, Chang Yong aluminium extruded type and die-casting die radiator now, fixed-type owing to be subject to machining, make it will be corresponding to the higher electronic building brick of caloric value the time, must increase its volume improving heat-sinking capability, but make weight increase thereupon; And the fin of folded form is comparatively frivolous, and increases its area of dissipation by the storehouse connected mode, so when being used for the higher electronic building brick of caloric value, its heat-sinking capability is also preferable, and is also comparatively convenient on using.

As shown in Figure 1, fin 1a for general known folded form, this fin 1a is the plate 10a that its punching out is become several certain sizes with the continuous impact style of machinery, and be formed with flanging 11a in its two ends, this two folding 11a is parastate, and make end face be a  type shape, and this plate 10a of institute's punching out utilizes heat-conducting glue to be attached on the cooling base 2a of electronic building brick with its flanging 11a one by one respectively, reaches radiating effect.

But, one by one this plate 10a is adhered on the cooling base 2a with heat-conducting glue, so, bring inconvenience when not only making assembling, and expend man-hour, more need waste more heat-conducting glue and increase cost, be unsuitable for a large amount of productions, its deficiency in economic performance.

As from the foregoing, above-mentioned known folded form fin in the actual production assembling, obviously has inconvenience and exists with shortcoming, and remain to be improved.

The purpose of this utility model is to propose a kind of a kind of groups of fins assembling structure reasonable in design and that effectively improve above-mentioned shortcoming and improves.

The purpose of this utility model is achieved in that provides a kind of groups of fins assembling structure to improve, and it comprises:

Several plates, its edge is formed with flanging; And

Several joggle mechanisms, it is located on the flanging of plate, and includes joggle breach and joggle portion, and the mutual joggle of this joggle breach and joggle portion engages, so that the continuous joggle polyphone of this plate is formed a fin.

Cooling base with itself and electronic building brick fits again, and will not be adhered to one by one on the cooling base by the individual boards sheet, makes assembling more convenient, thereby can save man-hour and reduce the cost of heat-conducting glue, and can be suitable for a large amount of productions; In addition, this fin is because of the polyphone joggle forms several runners, also can be provided with through hole in this plate, makes this runner thereby communicates, to improve radiating effect.

Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, so that further understand feature of the present utility model and technology contents.Yet appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.Wherein:

Fig. 9 is the three-dimensional exploded view of the utility model the 5th embodiment;

Figure 10 is the three-dimensional exploded view of the utility model the 6th embodiment.

See also Fig. 2, Fig. 3 and Fig. 4, be respectively three-dimensional combination figure of the present utility model, three-dimensional exploded view and A-A cutaway view.A kind of groups of fins assembling structure provided by the utility model improves, the composition mode of this fin 1 is the plate 10 that its punching out is become several certain sizes with the continuous impact style of machinery, this plate 10 is made by thermal conductivity good metal materials such as aluminium or copper, it utilizes the edge of plate 10 to form flanging 11, this flanging 11 slightly tilts laterally, and be provided with joggle mechanism 12, and the area of this flanging 11 can be the part and is connected on the plate 10, circulates in order to air diffuser; Or be connected in for whole piece on the end of plate 10, and can form runner 15, air is circulated by both sides.

This joggle mechanism 12 includes a joggle breach 13 and a joggle portion 14, the flanging 11 places punching out of this plate 10 has joggle breach 13, and the edge of flanging 11 is provided with corresponding joggle portion 14, engage by this joggle breach 13 and joggle portion 14 mutual joggles, make this plate 10 joggle fin 1 that is connected in series continuously.

The shape of this joggle mechanism 12 can be arbitrary shapes (as Fig. 5 and shown in Figure 6) such as circle, triangle, square or polygon, the size of the visual plate 10 of its quantity and appropriateness increase and decrease.In addition, this fin 1 forms several runners 15 because of piling up joggle, and this runner 15 is to separate because of plate 10, also can be provided with through hole 16 in these plates 10, makes this runner 15 thereby communicates, to improve radiating effect.

As shown in Figure 7, the flanging 11 of these plate 10 tops is local connection status, to form an open space, be beneficial to air turnover runner 15, also can be as shown in Figure 8, flanging 11 is located on the dual-side of plate 10, but 11 contacts area because of need increase and cooling base 2 of the flanging of these plate 10 belows are to improve its radiating efficiency, so the flanging 11 of general plate bottom is a whole piece, and the quantity of flanging also can cooperate the quantity of joggle mechanism and increases and decreases.

As Fig. 9 and shown in Figure 10,,, so,, can reach the purpose of saving material though sacrifice the area of dissipation of a little with flanging 11 bending formings by the material at plate 10 edges.

It is with joggle mechanism 12 these plate 10 polyphone joggles to be shaped that the utility model groups of fins assembling structure improves, the fin of more known folded form is more convenient when assembling, and can save more the multiplex (MUX) time, also can reduce the waste of heat-conducting glue, and have high aspect ratio and high density area of dissipation, when making this fin 1 be attached on the cooling base 2 of electronic building brick, can effectively increase its area of dissipation, the radiator of also more known aluminium extruded type and die-casting die has better heat-sinking capability.

In sum, the utility model is real in improving the known folded form fin that one by one plate is attached joint with heat-conducting glue, it causes quite inconvenience this known fin in assembling, also waste material (heat-conducting glue), expend man-hour, thereby do not have a problem such as economic benefit; The utility model is rare utility model product, and it really can reach the application target of expection, and solves the problem of known technology, has novelty, creativeness and practicality.

The above only is a preferable possible embodiments of the present utility model, non-so promptly arrest limit claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all should be contained in the claim scope of the present utility model.
