Description

heat sink

technical field

The invention relates to a radiator, in particular to a radiator for dissipating heat from electronic components.

Background technique

The electronic components installed on the circuit board will generate a lot of heat during operation. If the heat cannot be effectively dissipated, it will directly lead to a sharp rise in temperature, which will seriously affect the working performance and life of the electronic components. For this reason, a heat sink is usually installed on the electronic components to dissipate heat.

A traditional heat sink is formed by buckling a plurality of fins spaced apart from each other, and each fin includes a body and folded edges formed by bending from two sides of the body along one side. A plurality of buttonholes are opened on each folded edge and a plurality of button pieces are formed. The folded edges at both ends of each fin extend in the same direction and abut against the bodies of adjacent fins, so that the intervals between the fins are maintained. The flaps along the two ends of the fins are fastened to each other through the buckle pieces and the buckle holes. However, after the operator finishes fastening all the fins, the hem and buckle of a fin located at the end of the radiator are directly exposed, which is easy to scratch the operator.

Contents of the invention

In view of this, it is necessary to provide a heat sink with an anti-scratch structure.

A heat sink, which includes a fin group, the fin group includes a plurality of interlocking first fins and interlocking with the outermost first fin among the interlocking first fins A second fin connected to the second fin has a first body and a first folded edge formed by bending from one side of the first body. The first folded edge is provided with a first button hole and is connected with the first folded edge. A first buckle piece adjacent to the buckle hole, the radiator also includes a buckle plate, the buckle plate includes a second body and a second folded edge formed by bending from one side of the second body, the second folded edge of the buckle plate Facing and abutting against the first edge of the second fin, the first buckle of the second fin passes through the buckle plate to buckle them together.

Compared with the prior art, the heat sink of the present invention not only makes the heat sink look more beautiful by fastening the pinch plate into the second fin, but also effectively solves the problems in the process of assembling and using the heat sink. The problem of scratching the operator in the middle.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

As shown in FIGS. 1 and 2 , a heat sink 1000 according to an embodiment of the present invention is used for dissipating heat from an electronic component, and includes a fin set 100 and a pinch plate 11 . The fin set 100 includes a plurality of interlocking first fins 10 and a second fin 102 at the end. The first and second fins 10, 102 and the pinch plate 11 are all made of metal materials with good thermal conductivity such as copper and aluminum.

Please refer to FIG. 3 and FIG. 4 at the same time, each of the first and second fins 10 , 102 includes a rectangular body 12 . The top and bottom edges of the main body 12 respectively extend perpendicular to the main body 12 to form two folded edges 14 at intervals. Each folded edge 14 defines a button hole 16 . Each buttonhole 16 includes a body portion 164 and an extension portion 162 . The edge of the main body 12 extends outwardly in each button hole 16 to form a protrusion 122 . The folded edge 14 of each first fin 10 extends in the same direction and abuts against the body 12 of the adjacent first fin 10 , so that the first fins 10 are equidistant from each other.

Please also refer to FIG. 6 , a buckle 18 extends horizontally outward from the outer edge of each folded edge 14 of the first fin 10 near each buckle hole 16 . Each buckle 18 includes a body portion 184 adjacent to the buckle hole 16 and an extension portion 182 extending outward from the body portion 184 . The main body portion 184 of the buckle piece 18 is adjacent to the extension portion 162 of the buckle hole 16 . The width of the main body portion 184 is greater than that of the extension portion 182 . The distance H extended by the extension portion 162 of each buckle hole 16 is equal to the distance D extended by the extension portion 182 of each buckle piece 18 plus the thickness of the protrusion 122 . The folded edges 14 along both sides of the first fins 10 are fastened to each other through the buckle pieces 18 and the buckle holes 16 .

Please refer to FIG. 5 at the same time. For convenience of description, two adjacent first fins 10 are respectively labeled as 10a and 10b in FIG. 5 . The body portion 184 of the buckle 18 of the first fin 10a is correspondingly accommodated in the body portion 164 of the button hole 16 of the first fin 10b, and the extension portion 182 of the buckle 18 of the first fin 10a is correspondingly accommodated in the first fin 10b. The extension 162 of the button hole 16 of the first fin 10b, the extension 162 of the button hole 16 of the first fin 10a corresponds to the protrusion 122 of the first fin 10b, so that the first fin 10a and the first The fins 10b snap together.

Referring to FIG. 4 , a clasp 18 a extends outward from the outer edge of each folded edge 14 of the second fin 102 . The gusset 11 includes a rectangular body 13 and two folded edges 15 extending from two opposite sides of the body 13 perpendicular to the body 13 . Four buttonholes 17 are defined on the edge of the main body 13 near the edge 15 corresponding to the buckle 18 a of the fin 102 . In order to match the four buckle holes 17 of the buckle plate 11, the position of the buckle 18a of the second fin 102 is closer to both ends than the position of the buckle 18 of the first fin 10; The width of the buckle 18 a of 102 is smaller than the width of the buckle 18 of the first fin 10 and equal to the width of the buckle hole 17 of the buckle plate 11 .

The pinch plate 11 is placed inside the second fin 102 , the folded edge 15 of the pinched plate 11 is facing the folded edge 14 of the second fin 102 and abuts against the inside of the folded edge 14 of the second fin 102 , The buckle 18 a of the second fin 102 is folded into the buckle hole 17 of the buckle plate 11 to buckle the second fin 102 and the buckle plate 11 .

It can be understood that the number of folded edges, button holes and button pieces of the first and second fins 10 , 102 and the buckle plate 11 can be one or more, and is not limited to the numbers described in the above embodiments.

By buckling the buckle plate 11 into the second fin 102, not only the radiator 1000 looks more beautiful, but also effectively solves the problem of the radiator 1000 causing scratches to the operator during assembly and use. question.
