Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

The heat sink with excellent heat dissipation performance provided by the present embodiment, as shown in fig. 1 and fig. 2, includes a bottom plate 1 and a plurality of heat dissipation fins 2 disposed on the bottom plate 1, a round chamfer 3 is disposed at a joint of the heat dissipation fins 2 and the bottom plate 1, and a thickness of the heat dissipation fins 2 gradually increases from top to bottom. Preferably, the heat dissipation fins 2 are integrally designed with the base plate 1, and all the heat dissipation fins 2 have the same height.

Specifically, a product needing heat dissipation is fixed on one side of a bottom plate 1, and the product is dissipated through a heat dissipation sheet 2 on the other side of the bottom plate 1; the connecting part of the radiating fin 2 and the bottom plate 1 is provided with the round chamfer 3, so that the difficulty of a production process can be reduced, compared with a right-angle design, the problem of burrs easily occurring at a right angle in a production process can be reduced, and the round chamfer 3 has a better heat conduction effect, so that the radiating effect of the radiator can be effectively improved; in the prior art, the heat conduction area of the heat sink 2 is increased by making the heat sink 2 into a wave shape, so that the heat conduction area is increased, but the volume of the heat sink 2 is increased, so that the middle amount of the heat sink is increased, and the cost is higher; in this embodiment, the heat dissipation plate 2 is configured to be thin at the top and thick at the bottom, one function is to increase the heat conduction area of the heat dissipation plate 2, so as to further improve the heat dissipation effect, and the other function is to reduce the volume of the heat dissipation plate 2, so as to reduce the weight of the heat sink and achieve the effect of saving the cost.

In the heat sink with excellent heat dissipation performance provided by the present embodiment, as shown in fig. 2, the top of the heat sink 2 is set to be a round corner 4.

In particular, in actual production, the right-angled design is prone to generate burrs, and the right-angled edge is sharp, and is prone to scratching products or scratching users. This embodiment sets up the top of fin 2 into fillet 4, can avoid producing the burr to fillet 4 can increase heat conduction area, improves the radiating effect of fin 2.

As shown in fig. 1 to 3, the bottom plate 1 is provided with a plurality of screw holes 5, and the thickness of the position of the bottom plate 1 where the screw holes 5 are provided is greater than the thickness of the position of the bottom plate where the screw holes 5 are not provided; the screw hole 5 does not penetrate through the bottom plate 1; the screw hole 5 is used for fixing a product to be cooled.

Specifically, the base plate 1 in the prior art is generally equal in thickness, the screw holes 5 are formed in the base plate 1 with uniform thickness, and when the screw holes 5 penetrate through the base plate 1, burrs are often generated on the edges of the screw holes 5 due to stress action on the base plate 1, and the burrs need to be ground flat manually; if the thickness of the base plate 1 is increased, the material cost is increased and the weight of the heat sink is increased. Therefore, in this embodiment, the bottom plate 1 is thickened at the position where the screw hole 5 needs to be formed, as shown in fig. 1 and fig. 2, the screw hole 5 can be prevented from penetrating through the bottom plate 1, the material cost of the bottom plate 1 can be avoided being increased, burrs do not need to be ground manually, the labor cost can be further saved, and the production efficiency is improved.

In the heat sink with excellent heat dissipation performance provided by the present embodiment, as shown in fig. 1 and fig. 2, two sides of the bottom plate 1 are respectively provided with a protruding clamping strip 6; the edge of the clamping strip 6 is provided with a chamfer 7.

Specifically, the card strip 6 of bottom plate 1 both sides can be used for being fixed in the radiator on other articles, for example have the case of draw-in groove, sets up the edge of card strip 6 into chamfer 7, makes the technology production simpler, and chamfer 7 is difficult to produce the burr, can reduce the process of grinding the 6 edges of card strip when then producing the radiator to can improve production efficiency.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
