New description: [New technical field] This creative department is a kind of combined heat sink with extended telescopic, especially the kind of heat sink is formed by stamping and forming a heat sink. The contact area is the largest to increase the heat dissipation. [Prior Art] According to the conventional heat-dissipating structure which is commonly connected to each other by a snap, as shown in the figure, a heat dissipating body 100 is provided. The heat sink 11 is formed by a plurality of fins 11 , and the flaps 12 are bent at 90 degrees to the side of the heat sink 11 . The flaps 120 are provided with openings 121 at the junctions of the heat sinks 110 . An outwardly extending latching piece 122 is disposed on the end of the flap 120 opposite to the opening 121. The two sides of the latching piece 122 are provided with an outwardly folded bent portion 123. The clips 122 of the flaps 120 on the heat sink 110 are snapped into the openings m of the flaps 12 of the adjacent fins 110. Thus, the above-mentioned actions are repeated to form a heat sink. However, such a device and structure still have the following disadvantages: 1. Since the conventional heat sink 100 is continuously snapped in the opening 121 of the adjacent heat sink 110 by the snap tab 122 on the flap 120, the last heat sink is removed. The latching piece 122 of the latch 110 is snapped into the opening 121 of the J-th heat sink 110 to form an annular heat sink 1〇〇, but since the heat sinks Π0 are made of the flaps of the adjacent heat sink no The 12-inch edge abuts in a line, so the supporting force of the radiator is relatively weak. 2. Since the bent portions 123 on both sides of the clip piece 122 are folded outward after being inserted into the adjacent opening 121, the processing is complicated. 3. Since the flap 120 is in contact with the heat source, the card joints using the snap-on method are presented on the surface of the flap 120, so that the surface of the flap 120 is uneven, resulting in The heat sink 110 cannot be closely attached to the heat source, resulting in poor heat conduction. [New Content] Creation Outline: 5 M342541 In order to improve the various shortcomings of the heat dissipation structure of the above-mentioned combination of mutual snapping, the creator has been working hard to study and experiment, and finally developed and designed the combined heat sink of this creation with extension and expansion. . The creation-series of the present invention provides a heat sink with a plurality of sheets formed by stamping, and a heat sink having a bent piece at least on one side of the heat sink. And the heat sink is perpendicular to the heat sink, and the connecting piece is connected to the other side, the flap is attached to the heat sink, and extends in the same direction as the heat sink, and at least the side of the heat sink The side is provided with an outwardly extending snap tab, and a side of the heat sink is also provided with a __ human snap groove, which can be respectively used for snapping the snap tab; The heat sink can be formed by snapping the snap tabs on the flaps with the snap grooves of the heat sinks of the fuses - the heat sink, so that the fasteners are attached to the heat sinks On the folded sheet extending in the same direction, the connecting shirt in contact with the heat source may be uneven, and the large contact area may be placed on the heat source to increase the heat dissipation effect. The other purpose of this creation is that the snap groove and the snap tab are difficult to be scattered and folded, and the conventional technique is simple and easy to use in stamping. The purpose of the present invention is to increase the support of the body by means of the flaps (4) by arranging the sheets together with the fins through the connecting sheets and the fins. force. The re-purpose of this creation is to provide a combination heat sink with extended stretching and expansion, and to increase the i-direction extended flap, so that it can be increased compared with the combined type of loose material. [Embodiment] The present invention is a combined heat sink with extended expansion and contraction. Please refer to Figures 2 and 3, which are the first embodiment of the present invention. The heat sink 10 includes at least a plurality of heat sinks. In the sheet 20, the heat sink is at least-side-connected with a 90-degree f-fold connection #21 (one side in this embodiment), and the connecting piece 21 is connected to the other side with a flap 22' The sheet 22 and the fins 20 are spaced apart from each other and extend in the same direction, and the flaps 22 are provided with outwardly extending latching pieces 221 at least on the side edges, which are two side edges in this embodiment. Further, on the side of the heat sink 20, opposite to the snap tab 221, a snap groove 201 is provided which cooperates with the snap tab, such as 6 M342541, and the snap groove 201 has a predetermined depth ( As shown in a of FIG. 3, in the present embodiment, it is the same as the thickness of the heat sink). When assembling, please refer to FIG. 3, firstly insert a snap tab 221 of a heat sink 20 in the snap groove 201 of the adjacent heat sink 20, and bend the snap tab 221 inwardly. Covering the surface of the heat sink 2, through the above-mentioned action, a heat dissipating body 1 arranging in a rectangular shape can be formed, so that the fastening points of the heat sink 20 are attached to the heat sink 20 in the same direction extending the flap 22, and the contact surface with the heat source (not shown) (ie, the surface area of the scale tab) is straight, and can completely abut the heat source, and increase heat dissipation Moreover, since the snap groove 201 and the snap tab 221 are respectively on the heat sink 2〇X and the flap 22, it is simple and easy to press and form. In addition, since the flap 22 is in contact with the heat sink 20 through the connecting piece 21, the heat sink 2 is arranged in the B, and the flap 22 can be abutted against the heat sink by the surface. 2, the support force of the heat sink 10 is increased, and at the same time, each of the heat sinks 2 increases the surface area of the flaps 22, which also increases the heat dissipation area. Referring to Figures 4, 4A, and 5, it is a second embodiment of the present invention, which is different from the first embodiment in that the heat sink 20 is connected to the side with a 90 degree bend. a piece 21, and the other side of the connecting piece 21 is respectively provided with a flap 22 which is spaced apart from the fin 2 2 and extends in the same direction, and the fold 4 22 is provided at least on the side The outer extending latching piece 221 is provided on both sides of the embodiment. In addition, the heat sinking piece 20 and the locking piece 221 are oppositely provided with the engaging buckle groove 2〇1. During assembly, the snap tabs 221 of the flaps 22 on the heat sink 20 are first nested in the latching slots 201 of the adjacent fins 2, and the latching tabs 221 are bent and wrapped around the fins 2 On the surface of the crucible, after repeating the above actions, the clip piece 221 of the last fin 20 is snapped into the snap groove 201 on the second fin fin 2, and the ring-shaped strip can be formed.雠10, the inner edge of the annular heat sink 1# is wrapped around the heat source (not shown), so that the clips 22 of the heat sinks 2 The fins 20 are extended on the flap 22 in the same direction, and the heat dissipating effect can be increased, and the heat dissipating system is arranged in a ring shape, and the flap 22 abuts against the fins 2 in a surface manner. The supporting force of the heat sink 10 is increased. ^ Please refer to FIG. 6, which is a third embodiment of the present invention, which is different from the second embodiment in 7 M342541. The heat sink 20 has a beveled upper portion and a flat portion at the lower portion. a connecting piece 21 bent at a 9G degree is attached to the side of the flat fin of the heat sink 2, and the connecting piece 21 is further provided with a flap 22, which is coupled with the heat sink. 2〇 maintaining a certain distance and extending in the same direction, the flap (2) is provided with a fastening piece 221 on at least one side thereof, the fastening piece 221 is bent inward, and the heat sink 2〇 and the buckle piece are included. 221 is located at the opposite side with the matching buckle groove 2〇' In summary, the creation is first created in terms of article, shape, structure and structure, and can improve various shortcomings of the conventional technology, and can improve the effect in use. It is practical and fully compliant with the new patent requirements, which is an ideal creation. [Simple description of the drawing] _ 1®· is an exploded view of the conventional structure.
