Description

Fin set

technical field

The utility model relates to a heat dissipation assembly, in particular to a heat dissipation fin group composed of several heat dissipation fins.

Background technique

At present, the existing heat dissipation fin groups generally have two types: side-by-side serial connection and ring connection. One of the existing technologies will be selected below to describe the related shortcomings.

Please refer to FIG. 1 , a conventional side-by-side series-connected heat dissipation fin group includes a piece 30, and the two sides of the piece 30 are punched and bent to form two side walls 31 respectively. The sides of the side walls 31 At least one pressing piece 311 is formed on the top edge, and a fastening hole 32 is punched on the top surface of the sheet body 30 corresponding to the pressing piece 311. The fastening hole 32 is in the shape of gradually expanding from the top edge to the bottom edge. 311 corresponds to the fastening hole 32 and is also in the shape of gradually expanding from the top edge to the bottom edge. When the user wants to combine the two heat dissipation fins with each other, because the bottom edge of the pressing part 311 of the one heat dissipation fin is larger than the top edge of the fastening hole 32 of the other heat dissipation fin, it is necessary to force the two heat dissipation fins together. The pressing part 311 of the cooling fin is combined with another fixing hole 32 of the cooling fin, so that the existing side-by-side series-connected cooling fin group has the following disadvantages:

1. Inconvenient assembly: when assembling each heat dissipation fin of the existing heat dissipation fin group, additional force is required to force the fastening part of one heat dissipation fin into the fastening hole of another heat dissipation fin. This makes the existing cooling fin set have the disadvantage of inconvenient assembly.

2. Poor stability: because the assembly of the existing heat dissipation fin is forced in, it is easy to deform the pressing part of the existing heat dissipation fin and the fixing hole of another existing heat dissipation fin. The phenomenon of looseness occurs, so that the existing heat dissipation fins cannot be firmly engaged with each other, and has the disadvantage of poor stability.

Another example is the patent case of China Taiwan Certificate No. M268888 "Radiation Fin Fastening Structure of Ring-connected Radiator", which discloses an existing ring-connected heat dissipation fin group. The two sides are respectively connected with a large folded edge. The large folded edge has a fastening convex part, an abutting part and another small folded edge. The small folded edge has a buckled concave part and an insertion convex part. When several heat dissipation fins are fastened together, the insertion convex part of each heat dissipation fin is fastened into the insertion hole of the other heat dissipation fin connected, and the fastening convex part and the fastening concave part of another heat dissipation fin are used Closely arranged and fastened to form a closed ring, the existing ring-connected heat dissipation fins are combined in a manner that the convex part is inserted into the recess, so that the existing ring-connected heat dissipation fins have the disadvantage of inconvenient assembly.

During the actual assembly of the existing ring-connected heat dissipation fin group, the insertion protrusion of one heat dissipation fin must be aligned and buckled into the insertion hole of the other heat dissipation fin connected, and the fastening protrusion must also be used The fastening recesses of another heat dissipation fin are closely arranged and fastened to form a closed ring shape. The assembly process of the existing ring-connected heat dissipation fin group needs to carry out the fastening of the insertion convex part and the insertion hole, and the fastening Only two combining steps of the convex part and the fastening concave part can constitute a closed ring-mounted ring-connected heat dissipation fin set, which makes the existing ring-connected heat sink fin set have the disadvantage of inconvenient assembly.

Utility model content

The main purpose of the present utility model is to provide a heat dissipation fin set to improve the disadvantages of inconvenient assembly, poor stability and poor usability of the existing heat dissipation fin sets.

In order to achieve the aforementioned creation purposes, the technical means used in the utility model and the effects that can be achieved by means of the technical means include:

A heat dissipation fin group is formed by combining several heat dissipation fins. The heat dissipation fins include a heat dissipation plate and a joint portion. The joint portion is formed at one end of the heat dissipation plate. The two side edges of the joint portion are respectively bent Fold to form one side wall, the opposite surface of the two side walls is a fitting surface, the two side walls are respectively provided with a connecting piece protruding to the fitting surface, the top edge of the connecting piece is formed with an anti- The joint part is provided with a perforation aligned with the connecting piece; the detachment part of the one heat dissipation fin can be bent and easily penetrate the through hole of the other heat dissipation fin without destroying the shape of the perforation , and use a tool to push the bending of the anti-loosening part to the side wall of the other heat dissipation fin, so that the anti-loosening part will generate an expansion force on the side wall of the other heat dissipation fin, and then Closely attached to the side wall of the other heat dissipation fin, the heat dissipation fin set of the present invention has the functions of facilitating assembly and improving the stability of the connection structure.

Therefore, the beneficial effect of the utility model is to make the cooling fin group have the functions of convenient assembly and improving the stability of the connecting structure.
