Embodiment
Below in conjunction with accompanying drawing feature of the present utility model and technology contents are elaborated, listed accompanying drawing is only for reference, is not to restriction of the present utility model.
As shown in Figure 2, heat abstractor 10 of the present utility model is used for the heat radiation of CPU 20, mainly is made up of first heat-sink unit 1, second heat-sink unit 2, a radiator fan 3 and a plurality of heat pipe 4.Wherein, this first heat-sink unit 1 is made of one piece by a plurality of aluminium extruded type fin 11, is arranged on the CPU 20, is respectively equipped with fixing hole 12 at first heat-sink unit 1 four jiaos, is used for fixing radiator fan 3.
This heat pipe 4 is " ㄈ " font, has the working fluid that is used for absorbing heat in the heat pipe 4.Present embodiment is provided with two heat pipes 4 side by side, and heat pipe 4 is made up of with the stay pipe 43 of push pipe 42 bottom tube 41, a push pipe 42 and binding bottom tube 41.Bottom tube 41 is fixedly installed in the groove 13 of bottom of first heat-sink unit 1, and is set directly on the CPU 20.Certainly, also a heat-conducting block that is made of copper 14 (as Fig. 5, shown in Figure 6) can be set in the bottom of first heat-sink unit 1, and the bottom tube 41 of heat pipe 4 is fixedly installed in the heat-conducting block 14.
As shown in Figure 2, this second heat-sink unit 2 is made of the radiating fin 21 that multi-disc is set up in parallel, horizontally set through hole 22 on these radiating fins 21.The push pipe 42 of heat pipe 4 is arranged in the through hole 22 of these radiating fins 21, makes second heat-sink unit 2 be fixed on the top of first heat-sink unit 1, and is reserved with the space between the two, and radiator fan 3 is installed in this space.The employed radiator fan 3 of present embodiment is an axial flow fan, is fixedly installed on first heat-sink unit 1.
As shown in Figure 3, the utility model when assembling because this first heat-sink unit 1 is made of aluminium extruded type fin 11, have fixing hole 12, therefore, make radiator fan 3 be installed in first heat-sink unit, 1 top earlier, and make radiator fan 3 on blow downdraft; Then, be fixed on the fixing hole 12 of 1 four jiaos of first heat-sink units with bolt assembly 5 again, thereby make radiator fan 3 be fixed on the top of first heat-sink unit 1.
Then, the push pipe 42 of two heat pipes 4 is arranged on the through hole 22 of radiating fin 21 of second heat-sink unit 2, the bottom tube 41 of heat pipe 4 then is embedded in the set groove 13 in first heat-sink unit, 1 bottom, radiator fan 3 is between first heat-sink unit 1 and second heat-sink unit 2 just, and formation a pair of laminar heat abstractor 10, and make between second heat-sink unit 2 and the radiator fan 3 and be reserved with space 101, promptly can be assembled into as Fig. 4, heat abstractor 10 shown in Figure 5.
As shown in Figure 6, when this heat abstractor 10 was installed on the CPU 20, the most of heat that is produced during CPU 20 work can be transmitted to heat pipe 4, by its working fluid, conducts heat on second heat-sink unit 2 again.After radiator fan 3 rotation, owing to blow down the characteristic of suction on the radiator fan 3, dispel the heat in second heat-sink unit 2, and air is blown into first heat-sink unit 1 dispels the heat and the air in the external world sucked.
In addition, because be reserved with space 101 between this second heat-sink unit 2 and the radiator fan 3, cool ambient air also can directly be sucked first heat-sink unit 1 from side by radiator fan 3 and dispel the heat.
In the utility model,, and only utilize a radiator fan 3 just simultaneously two heat- sink units 1,2 to be dispelled the heat because this heat abstractor 10 is made up of 1,2 of two heat-sink units, thus the radiating efficiency of entire heat dissipation device 10 can be improved, and assemble very convenient.
In sum, the utility model can pass through above-mentioned structure really, produces described effect.And the utility model is not disclosed use, and also not record on the various publications before the application meets the important documents such as novelty, creativeness of novel patent application fully.
More than to the explanation of preferred embodiment of the present utility model, be not to be used for limiting claim of the present utility model, the equivalent transformation of any application feature of the present utility model and technology all belongs to scope of patent protection of the present utility model, hereby statement.
