SUMMARY OF THE INVENTION The main object of the present invention is a structurally stable one. The present invention provides a heat dissipating device, which is assembled quickly. The heat dissipating device provided by the present invention comprises a plurality of plates that are coupled to each other, wherein the plate member has a body, and the first side J is composed of a forest body. a side extending downwardly, and a second side wall extending downwardly from the body; the body having an indentation, the first side wall being provided with an aperture and a hook piece, the hook piece being fastened Inserting the inserts of the other plate members at the bottom end of the first side wall and extending downwards Θ ,, thereby engaging each plate member at - 20 1259054. [Embodiment] In order to explain in detail the structure and features of the present invention, BRIEF DESCRIPTION OF THE DRAWINGS The following is a side view of a preferred embodiment of the present invention; the third drawing is a top view of a preferred embodiment of the present invention; The four figures are assembled diagrams of a preferred embodiment of the present invention. 2 to 4, a heat dissipating device 10 according to a preferred embodiment of the present invention includes a plurality of boards 20 that are snapped together, wherein the board 1 〇 20 has a rectangular body 3〇, a first The side wall 4 向下 extends downward from the side of the body 3 , and a second side wall 5 向下 extends downward from the other side of the body 3 . The body 30 has two through holes 32 adjacent to the first side wall 4 and the first side wall 50. The first side wall 40 is provided with a through hole 42 and a hook piece 44. The through hole 42 is semicircular and adjacent to the body 3 ,. In fact, the through hole 42 and the insertion hole 32 are mutually connected to each other. The hook piece 44 is disposed at a bottom end of the first side wall 40 and extends downward. The hook piece is privately provided with a pleat 46. The second side wall 50 is provided with a through hole 52 and a hook piece 54. The top end of the hook piece 54 is provided with a pleat 56. The structure is the same as that of the first side wall 40, and the structure of the heat dissipating device 10 is assembled. As shown in the fourth figure, one of the hook pieces 44, 54 of one plate member 2 is first inserted into the other plate member 2, the insertion hole 32, and then passed through the other plate member 2 by the two top posts 60. 〇, the second of the perforations 42, 52, and the top of the 1259054: the hook of the plate 2 &> 44, 54 'two top posts 6G pressure to deform the two hooks 44, the pleats 46, 56 The existence of the deformation can be easily caused, such as ^ 2 card 2G card is connected, and the heat sink 10 is completed. The heat sink 1G provided by the present invention only needs to be used by two : Γ Relative ^ can complete the assembly, compared to the conventional structure must be clear one: the cover Xi: 'The assembly procedure is simple and fast', so the original two π - f σ,. The structure is missing to achieve the object of the present invention. A variety of enthalpy is that the structure of the provided heat sink can have the adjacent sides of the == body, the hook piece, the voyage or the second

A few can be changed as needed.
