Example 1
Referring to fig. 1, an integrated heat pipe 3 heatsink includes a thermally conductive base plate 1 for being disposed in close proximity to an element to be heat-dissipated, such as a processor of a computing device. In order to quickly dissipate heat of the heat-conducting bottom plate 1 after heat conduction, a plurality of heat pipe assemblies 2 are arranged on the heat-conducting bottom plate 1, each heat pipe assembly 2 comprises two heat pipes 3 which are oppositely arranged, in the embodiment, the heat pipes 3 are made of copper or aluminum materials, and the structure is solid or hollow.

The special-shaped fins 4 are plate-shaped metal sheets with thickness, and are attached and connected with the heat pipes 3. The special-shaped fins 4 are arranged on two sides of the heat pipe 3 far away from the mounting surface of the heat pipe 3, and two opposite special-shaped fins 4 form a flared opening 5 with a cross section at two sides of the heat pipe 3 so as to realize that the air flow flowing through the flared opening 5 accelerates the air flow velocity at the heat pipe 3 due to the narrowing of the flow passage, thereby realizing the improvement of the cooling efficiency. Therefore, the heat sink in this embodiment further includes a fan 6 provided on the housing of the heat conductive base plate 1, and the fan 6 is powered from the current apparatus to perform an operation. The air outlet of the fan 6 faces the wide opening 5 so as to realize that cold air is told to be blown into the wide opening 5, and the cooling efficiency is improved when flowing through the metal pipe.
Referring to fig. 2, the heat pipe assemblies 2 are used to cooperate with the fan 6 to realize active rapid cooling, and to further improve cooling efficiency, metal plates 7 are disposed on two sides of the heat conducting bottom plate 1 parallel to the air flow direction in the wide opening 5, and the metal plates 7 are made of copper or aluminum.

In one or more embodiments, the metal plate 7 is vertically provided with the heat conducting plate 9, two sides of the heat conducting plate 9 are respectively provided with a plurality of heat radiating fins 8 for passive heat radiation, and the heat conducting plate 9 is added to guide and arrange the heat radiating fins 8 at a position with wider space according to different installation environments, so that the heat radiating effect can be ensured. Because the radiating fins 8 are used for passive heat radiation, an air flow channel is not required to be designed, and the structure can be randomly arranged according to the installation environment, so that the radiator has higher flexibility.
Referring to fig. 1 and 4, in the present embodiment, a fan 6 is disposed at a heat pipe assembly 2 to achieve active heat dissipation with higher efficiency, but different degrees of noise are generated when the flow rate of air in an air duct changes, and under the condition that the heat dissipation effect is not affected, a noise reduction plate 10 is disposed at the end of the heat pipe assembly 2, and a noise reduction hole 11 for absorbing noise is disposed at a side of the noise reduction plate 10 facing the heat pipe assembly 2, where the noise reduction hole 11 in the present embodiment adopts a hexagonal honeycomb structure. Meanwhile, since the noise reduction plate 10 is disposed at the end of the heat pipe assembly 2, the cooling air flow can be restricted from overflowing toward the end of the heat pipe assembly 2, and thus the noise reduction plate 10 can further improve the utilization efficiency of the cooling air flow while achieving noise elimination.
