Abstract
The utility model discloses a cooling fin clamp structure. The cooling fin clamp structure disclosed by the utility model changes the buckling manner between metal sheets in the cooling fin, that is, the traditional buckling manner is changed into a clamp buckling point manner. When the clamp buckling point manner is adopted, the metal sheets in the cooling fin are spliced, and connection points between the metal sheets are tightly clamped together through one clamp boss, so that when the metal sheets in the cooling fin are buckled, the dependence on the line cutting precision of a line cutting machine can be reduced, that is, even the line cutting precision at the connection part is reduced, the connection between the metal sheets can be further fixed still through the clamp boss, and the connection between the metal sheets in the cooling fin is firmer.
Description
Technical field
The utility model relates to a kind of linkage structure of radiating fin, particularly relates to the snap-in structure between the tinsel in a kind of radiating fin.
Background technique
Radiating fin generally all is to be made to increase its heat diffusion area with stacked system by the multi-disc tinsel, and the linkage structure in the radiating fin between the tinsel can play crucial effects to the quality of finally making radiating fin.The big San Re of big radiating fin (Zhu ﹕ Pian ﹐ in our company's traditional heat-dissipating sheet need use the mould of 80T ﹐ 110T or 160T punch press to produce); the dependence You that line is cut precision is that Ming Xian ﹐ often has Bu Wen and Dings problems such as the ﹑ size is bad, inclination and occur all the time, is difficult in addition thoroughly improvement of the problems referred to above yet limit because of line cutting mill playscript with stage directions body precision conditions.In addition, because of the long-time edge of a knife that is caused of producing weares and teares, the product burr can increase gradually, thereby cause size to become big, problems such as inclination.
In sum, problem demanding prompt solution is to be improved to overcome above-mentioned defective the linkage structure of traditional heat-dissipating sheet.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of radiating fin snap-in structure is provided, it is by the structural feature of button point self, the influence that makes tinsel in the radiating fin be subjected to line cutting mill line to cut precision when fastening mutually diminishes relatively, and the stability that has improved product when radiating fin is produced.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of radiating fin snap-in structure, be used for the multi-disc radiating fin is fastened togather, and it comprises: tinsel, the joint with the adjacent metal sheet around it is suppressed with flanging; In addition, also comprise on the described flanging: the engaging joint, it protrudes from outside the flanging; Engagement groove, its shape matches with the described outer rim that engages joint; And snap fit tabs, after the outer rim of the engaging joint of adjacent metal sheet was inserted in the corresponding engagement groove, this snap fit tabs was blocked the inner edge front end of described engaging joint during engaging.
In the described radiating fin snap-in structure, last one deck of radiating fin is a bead layer, and its flanging does not have described engaging joint so that the outer surface of radiating fin is more smooth.
The utility model has the advantages that the radiating fin snap-in structure that the utility model disclosed has changed the manner between the tinsel in the radiating fin, promptly on the basis of traditional manner, increased a stuck point and fastened.When adopting stuck point to fasten, after pegging graft between the tinsel in the radiating fin, also the tie point between the tinsel is fastened togather closely by a snap fit tabs, rely on and diminish relatively thereby make tinsel in the radiating fin when fastening mutually, cut precision, also make connect between the tinsel in the radiating fin more firm simultaneously line cutting mill line.
Description of drawings
The plan view of monolithic radiating fin in Fig. 1 the utility model;
Fig. 2 is the rear view of monolithic radiating fin shown in Figure 1;
Fig. 3 is the structural representation after two radiating fin engage;
Fig. 4 is the structural representation that has the radiating fin of bead layer.
Embodiment
For further disclosing the technical solution of the utility model, be described with reference to the accompanying drawings mode of execution of the present utility model now.
The plan view of monolithic radiating fin in Fig. 1 the utility model, Fig. 2 is the rear view of monolithic radiating fin shown in Figure 1, Fig. 3 is the structural representation after two radiating fin engage, Fig. 4 is the structural representation that has the radiating fin of bead layer, above accompanying drawing shows the radiating fin that adopts the utility model radiating fin snap-in structure mode to be formed by connecting by the mode of example, it comprises: tinsel 10, joint with the adjacent metal sheet around it is suppressed with flanging 14, and the flanging 14 on this tinsel 10 is symmetric arrays usually; In addition, also comprise on the described flanging 14: engaging joint 11, its outer rim protrudes from outside the flanging 14; Engagement groove 12, its shape matches with the described outer rim that engages joint 11; Snap fit tabs 13, after the outer rim of the engaging joint 11 of adjacent metal sheet 10 was inserted in the corresponding engagement groove 12, this snap fit tabs 13 was blocked the inner edge of described engaging joint 11 during engaging.As further improvement, be called bead layer in the last one deck tinsel of radiating fin 10(the utility model), its flanging 15 does not have described engaging joint 11 so that the radiating fin outer surface of finally making is more smooth.
But the utility model is not limited to above-mentioned embodiment shown in the drawings, and every radiating fin that connects based on the utility model radiating fin snap-in structure is no matter and its radiating fin adopts which kind of shape, material etc. all should fall into protection domain of the present utility model.
The process of utilizing cassette button point of the present utility model that radiating fin is engaged below in conjunction with description of drawings.
During engaging, after inserting the engaging joint 11 on a slice tinsel 10 periphery flangings 14 in the engagement groove 12 corresponding on its adjacent metal sheet 10 periphery flangings 14 fully, the snap fit tabs 13 on the adjacent metal sheet 10 is blocked the inner edge front end of the engaging joint 11 in its engagement groove 12 of insertion so that this is engaged joint 11 firm being stuck in its engagement groove 12 at this moment.In addition, adopt bead layer when last one deck tinsel 10 of engaging radiating fin, this bead layer is consistent except its flanging 15 does not engage the joint 11 structure with other heat dissipating layer, so that the outer surface of radiating fin is more smooth.
In sum, when the mode that adopts stuck point of the present utility model to fasten engages radiating fin, after pegging graft successively by the engaging joint 11 on tinsel 10 flangings 15 and 12 pairs of tinsels 10 of engagement groove also by snap fit tabs 13 with 11 firm being stuck in the engagement groove 12 corresponding on its adjacent metal sheet 10 of the engaging joint on a slice tinsel 10.The line of tinsel 10 joints is cut still can do further fixingly when the line of precision in the joint cuts the situation that to reduce appear in precision thereby not exclusively depend on the line cutting mill when making tinsel 10 in the radiating fin fasten mutually, thereby improved the stability of finally making product by the connection between 13 pairs of tinsels 10 of snap fit tabs.
More than, basic design of the present utility model and basic principle have been set forth by description of listed embodiment.But the utility model never is limited to above-mentioned listed mode of execution, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on the technical solution of the utility model of change all should belong to protection domain of the present utility model.
