Abstract

A combined cooling rib includes a plurality of cooling ribs. Each cooling rib has a plate and a longitudinal part opposite. Wherein, the longitudinal part includes at least a card slot with a convex part inside whose front terminal extends outside to form a buckle slab. When all cooling ribs are assembled, the buckle slab on the convex part will be pressed to be folded into the adjoining card slot of the cooling ribs for fastening. The two sides of the cooling rib form a complete surface with a larger cooling area in order to enhance cooling capability and realize a more stable combination of all cooling ribs and avoid random separation.

Description

Fin combination structure

Technical field

The utility model provides a kind of Structure of radiating fin, makes the preferable radiating effect of fin performance especially, and effectively improves the fin combination of linking steady character.

Background technology

As shown in Figure 1, the structure of habit formula fin 10 mostly is thin slice greatly, its top more than 11 is provided with some breach 111, and a horizontal plate 121 is equipped with at 12 moderate places, bottom more, and respectively be equipped with gusset plate 13 at top, 11,12 2 corresponding front and back ends edges, the end, in order to when fin 1 during, the gusset plate 13 of last fin 10 is connected the gusset plate 13 of back one fin 10 with fin 1 winding.

From the above, after 10 windings of habit formula fin are finished, though can reach the effect of heat radiation, so because of 10 tops of the fin after the winding, 11,12 two ones the some breach 111 in the end and horizontal plate 121 structural design with gusset plate 13, make integral heat sink sheet group present rough state up and down, form some holes, make air-flow have some setbacks, cause the minimizing of the contact area of dissipation of fin 10, and windage is increased, and influence is installed in the air quantity of the radiator fan on the groups of fins, and then reduces the radiating effect of fin 10.

Moreover aforementioned stable degree in conjunction with design is very weak, when fin two ends court is pulled by relative direction.The fin 10 of stress raiser, the gusset plate 13 of one end will break away from the gusset plate 13 of adjacent fin 10, and under the situation that at one end breaks away from, the gusset plate 13 of end also will break away from the gusset plate 13 of adjacent fin 10 in addition, and make fin 10 dismember separation immediately.

Therefore, because the disappearance of above-mentioned habit formula fin combination structure, the utility model people is with the experience of being engaged in related industry for many years and professional technique, and adhering to research innovation, excelsior spirit, it is wider and meet the fin combination structure of industrial utilization to work out a kind of more practicality and range of application.

Summary of the invention

The utility model purpose is to provide a kind of fin combination structure, and the above-mentioned defective that it is to overcome traditional structure can make the preferable radiating effect of fin performance, and effectively improves the fin combination of linking steady character.

In order to achieve the above object, a kind of fin combination of the utility model structure, constituted by the number fin, its each fin has a body plate and and relative is extended the vertical component effect that constitutes by body plate both sides, and itself and body plate hang down and hand over, it is characterized in that: this vertical component effect includes one or more draw-in groove, has a protuberance in the draw-in groove, this protuberance length and vertical component effect equal in length, and this protuberance front end is expanded outside both sides a cramp that forms snapping in order to the draw-in groove that folds into adjacent fin is arranged.

Wherein, this protuberance length is identical with the length that this vertical component effect is extended from body plate both sides.

The utility model beneficial effect: to sum up institute is old, and the utility model fin combination structure is obviously practised formula fin combination structure and had more preferable radiating effect, and effectively improves the linking steady character between adjacent fin.

For the auditor can have further and understand the purpose of this utility model, feature, and function, lift a preferred embodiment now and cooperate graphic being described in detail as follows:

Description of drawings

Fig. 1: the schematic diagram that is habit formula heat radiating fin structure

Fig. 2: the stereogram that is the utility model fin.

Fig. 3: the winding stereogram that is the utility model fin.

Fig. 4: the cramp that is the utility model fin folds into schematic diagram.

The specific embodiment

See also Fig. 2 and shown in Figure 3, the utility model mainly is made of number fin 20, its each fin 20 has a body plate 2 and an opposing vertical portion 3, this vertical component effect 3 is extended by body plate 2 both sides, and with body plate 2 vertical friendships, wherein this vertical component effect 3 comprises two draw-in grooves 31, be formed with a protuberance 32 in these draw-in grooves 31 respectively, this protuberance 32 front ends expansion outside both sides respectively defines a cramp 321, use when 20 combinations of each fin, the cramp 321 of punching press protuberance 32 makes it fold into to form in the draw-in groove 31 of adjacent fin 20 and be fastened into groups of fins.

As shown in Figures 3 and 4, the length of extending from body plate 2 both sides because of this vertical component effect 3 is equal to protuberance 32 length, so when number fin 20 links mutually, this vertical component effect 3 is abutted against mutually and forms a spacing 4, and cramp 321 correspondences that this protuberance is expanded outside both sides are positioned on the draw-in groove 31 of adjacent fin 20, so when the cramp 321 of punching press protuberance 32, this cramp 321 promptly folds into and form buckle in the draw-in groove 31 of adjacent fin 20, make coinciding together that each fin 20 can be firm.

Continue the above, after each fin 20 mutual buckles binding of the present utility model are finished, the both sides that this fin is 20 groups form more complete plane, and have bigger area of dissipation, to increase heat radiation, and shown in scheming, be configured to example, on the two adjacent fin 20, four groups of protuberances 32 are arranged promptly, eight buckle points are provided, can strengthen by this 20 of adjacent fin in conjunction with stable degree, also significantly improve simultaneously resistivity to external force.

Claims

1, a kind of fin combination structure, constituted by the number fin, its each fin has a body plate and and relative is extended the vertical component effect that constitutes by body plate both sides, and itself and body plate hang down and hand over, it is characterized in that: this vertical component effect includes one or more draw-in groove, have a protuberance in the draw-in groove, this protuberance length and vertical component effect equal in length, and this protuberance front end is expanded outside both sides a cramp that forms snapping in order to the draw-in groove that folds into adjacent fin is arranged.

2, fin combination structure as claimed in claim 1, it is characterized in that: this protuberance length is identical with the length that this vertical component effect is extended from body plate both sides.
