The protection scope of the present invention is subject to the limitations defined by the appended claims.

Referring to fig. 1 to 3, fig. 1 is an exploded perspective view of a heat dissipation device 100 according to an embodiment of the present invention, fig. 2 is an enlarged view of a partial structure of the heat dissipation device 100, and fig. 3 is an assembled perspective view of the heat dissipation device 100. The heat dissipation device 100 includes a heat sink 10, a mounting bracket 20, and a fool-proof structure 30 disposed between the heat sink 10 and the mounting bracket 20. The heat sink 10 is used to dissipate heat from the electronic component. The mounting bracket 20 is used to mount the heat sink 10. The fool-proof structure 30 includes a protrusion 31 and a fool-proof hole 33 cooperating with the protrusion 31.

In the present embodiment, the protrusion 31 of the fool-proof structure 30 is disposed on the heat sink 10, and the fool-proof hole 33 of the fool-proof structure 30 is disposed on the corresponding mounting bracket 20. In other embodiments, the protrusion 31 of the fool-proof structure 30 can also be disposed on the mounting bracket 20, and the fool-proof hole 33 of the fool-proof structure 30 is disposed on the heat sink 10.

The heat sink 10 has an outer side wall 101. The outer side wall 101 of the heat sink 10 is further provided with at least one connection portion 11. Each connecting portion 11 is connected to a corresponding mounting bracket 20. In the present embodiment, the number of the connection portions 11 corresponds to the mounting bracket 20. Alternatively, the connecting portion 11 is triangular. The stability of the triangular shape enhances the strength and stability of the attachment of the mounting bracket 20 to the heat sink 10. Each connecting portion 11 includes three connecting blocks 111 distributed in a triangular shape and three reinforcing ribs 113 connecting two adjacent connecting blocks 111. For the die casting process of the connecting part 11, the design of the reinforcing rib 113 can not only improve the material feeding of the die, but also increase the strength of the final casting. It will be appreciated that in some embodiments, the connection portion 11 may also omit the reinforcing ribs 113. The protrusion 31 or the fool-proof hole 33 is provided on the at least one reinforcing rib 113. Since the protrusion 31 is engaged with the fool-proof hole 33 to constitute the fool-proof structure 30, the mounting bracket 20 can be mounted on the heat sink 10 in a correct orientation, thereby improving the assembling efficiency between the heat sink and the mounting bracket.

The three connecting blocks 111 and the three reinforcing ribs 113 may be integrally formed to simplify the structure of the connecting portion 11. The thickness of the connecting block 111 is the same as that of the reinforcing rib 113, that is, the connecting block 111 and the reinforcing rib 113 are located on the same plane on the side far away from the heat sink 10, so that the connecting portion 11 forms a complete outer end face, and the risk of the degree of fit reduction with the mounting bracket 20 caused by an irregular end face can be avoided. In some embodiments, the thickness of the stiffener 113 provided with the protrusion 31 or the fool-proof hole 33 is smaller than the thickness of the stiffener 113 not provided with the protrusion 31 or the fool-proof hole 33, thereby serving as a positioning function for mounting the heat sink 10 to the mounting bracket 20 in addition to achieving a correct mounting orientation.

In one embodiment, the protrusion 31 or the fool-proof hole 33 is provided on any one of the reinforcing ribs 113. In other embodiments, the protrusion 31 or the fool-proof hole 33 may also be provided on any two of the reinforcing beads 113, or on each reinforcing bead 113. The structural design of the protrusion 31 or the fool-proof hole 33 not only can realize that the heat sink 10 is accurately mounted on the mounting bracket 20, but also can reduce the stress caused by punching and bending the mounting bracket 20.

Alternatively, the protrusion 31 or the fool-proof hole 33 is located at the middle position of the reinforcing bead 113. In other embodiments, the protrusion 31 or the fool-proof hole 33 may be located at other positions of the stiffener 113, and is not limited herein. The number of the protruding portions 31 or the fool-proof holes 33 may be one or more to further reduce stress caused by blanking bending of the mounting bracket 20.

The mounting bracket 20 includes a first mounting portion 21 connected to the connecting portion 11 of the heat sink 10 and a second mounting portion 23 extending outwardly from the first mounting portion 21 toward an end portion away from the heat sink 10. The heat sink 100 is connected to an external device (not shown) through the second mounting portion 23. The first mounting portion 21 and the second mounting portion 23 form an included angle therebetween. Optionally, the included angle is a right angle or an obtuse angle. In other embodiments, the included angle may also be an acute angle. The first mounting portion 21 is provided with a fool-proof hole 33 penetrating through the first mounting portion 21 at a position corresponding to the protruding portion 31. In some embodiments, the first mounting portion 21 may further have a fool-proof groove that does not penetrate through the first mounting portion 21 at a position corresponding to the protruding portion 31.

It is understood that the first mounting portion 21 of the mounting bracket 20 is detachably coupled to the coupling portion 11 of the heat sink 10. For example, the first mounting portion 21 of the mounting bracket 20 may be fixedly coupled to the coupling portion 11 of the heat sink 10 by a screw or a magnetic attraction structure. Specifically, in the present embodiment, three screw holes 1110 matched with screws are opened in the middle of the three connecting blocks 111 of the connecting portion 11, and through holes 210 for passing the screws are provided at positions of the first mounting portion 21 corresponding to the screw holes 1110.

In the present embodiment, the protrusion 31 is disposed on a side of the rib 113 away from the heat sink 10 and is higher than the connecting block 111 and the rib 113, that is, the protrusion 31 is located on a different plane from the connecting block 111 and the rib 113 on the side away from the heat sink 10, so that the protrusion 31 can be accommodated in the fool-proof hole 33 disposed on the mounting bracket 20. The length of the protruding portion 31 exposed out of the reinforcing rib 113 is less than or equal to the axial length of the fool-proof hole 33, so that after the heat sink 10 is correctly installed on the installation bracket 20, the protruding portion 31 and the first installation portion 21 of the installation bracket 20 are located on the same plane on the side far away from the heat sink 10, and thus the first installation portion 211 forms a complete end surface, the risk of collision caused by an irregular end surface can be avoided, and the difficulty in installing other external elements caused by an irregular outer wall is avoided. The projection 31 has a columnar structure. The axial direction of the projection 31 is perpendicular to the outer side wall 101 of the heat sink 10.
