Abstract

The utility model relates to the technical field of heat sink, in particular to a computer heat sink. The computer heat sink comprises a pedestal made from graphite composite material, a radiator fin set made from copper or aluminium alloy, a fan and a bracket. A containing area is arranged at the bottom of the radiator fin set. The pedestal penetrates through the containing area. The bracket is fixed at the bottom of the radiator fin set. The fan is arranged at the top of the radiator fin set. The utility model uses the copper or aluminium alloy and the graphite composite material to manufacture the heat sink, the copper or aluminium alloy has high rigidity, can not be damaged easily and can be made into the radiator fin set with complex shape; the graphite composite material has fast heat conduction, high heat dissipation efficiency, light weight and low cost and can be used for manufacturing the pedestal, so the computer heat sink combines the advantages of both the copper or aluminium alloy and the graphite composite material, and the produced computer heat sink has the characteristics of low cost and high heat dissipation efficiency.

Description

A kind of computer radiating apparatus

Technical field:

The utility model relates to the heat abstractor technical field, particularly a kind of computer radiating apparatus.

Background technology:

As everyone knows, the chipset of computer or processor can produce high heat when running, and running speed is fast, driving electric power is high more, and the temperature of its generation is also just high more, if when chipset or temperature of processor are too high, will have influence on its normal operation, cause computer crash; Therefore, heat dissipation problem be if can't solve, will the limited chip group or the running speed of processor, cause the computer fluctuation of service.

Existing computer radiating apparatus mainly is made up of pedestal, radiating fin group and the auxiliary fan that dispels heat etc. of copper or aluminium alloy manufacturing, because resource is in short supply, the price of copper and aluminium progressively rises, and by the computer radiating apparatus that fine copper or aluminium are made, its cost is higher.And because the density of copper and aluminium is bigger, made computer radiating apparatus weight is big, damages chip easily by pressure, is inconvenient to install.

The utility model content:

The purpose of this utility model is to provide at the deficiencies in the prior art that a kind of cost is low, radiating efficiency is high, the significant computer radiating apparatus of cooling-down effect.

For achieving the above object, the utility model adopts following technical scheme:

A kind of computer radiating apparatus, it comprises radiating fin group, fan, the support that pedestal, copper or aluminium alloy that graphite composite material is made are made, described radiating fin group bottom offers and holds the district, pedestal is located in and holds in the district, support is fixed on radiating fin group bottom, and fan is arranged on radiating fin group top.

The rounded radiation shape of described radiating fin group, the described center that is positioned at this radiation shape of distinguishing that holds.

Described radiating fin group top is fixed with the fan housing that fan is covered, fan housing and radiating fin group snapping.

Form pilot hole on the described support, be equipped with reference column in the pilot hole.

Be arranged with spring on the described reference column.

Described pedestal passes support and forms boss, and boss is stuck on the support.

The utility model beneficial effect is: the utility model includes radiating fin group, fan, the support that pedestal, copper or aluminium alloy that graphite composite material makes are made, described radiating fin group bottom offers and holds the district, pedestal is located in and holds in the district, support is fixed on radiating fin group bottom, and fan is arranged on radiating fin group top; The utility model employing copper or aluminium alloy, graphite composite material are made heat abstractor; Copper or aluminum alloy hardness height, be not easy to damage, can manufacture radiating fin than complicated shape, and graphite composite material heat conduction is fast, radiating efficiency is high, in light weight, cost is low, can be used to make pedestal, so the utility model combines copper or aluminium alloy, both advantages of graphite composite material, produced computer radiating apparatus has the advantages that cost is low, radiating efficiency is high.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1～2, a kind of computer radiating apparatus, it comprises radiating fin group 2, fan 3, the support 4 that pedestal 1, copper or aluminium alloy that graphite composite material is made are made, radiating fin group 2 bottoms offer and hold district 5, pedestal 1 is located in and holds in the district 5, and the bottom surface of pedestal 1 closely contacts with CPU, and the pedestal of being made by graphite composite material 1 can pass to radiating fin group 2 to the heat on the CPU apace apace.Support 4 is fixed on radiating fin group 2 bottoms, and fan 3 is arranged on radiating fin group 2 tops, and the heat that can assemble radiating fin apace dispels away, reaches heat radiation, cool effect.Radiating fin group 2 can be the radiation shape of circle, holds the center that district 5 is positioned at this radiation shape.Radiating fin group 2 tops are fixed with the fan housing 6 that fan 3 is covered, fan housing 6 and radiating fin group 2 snappings.Form pilot hole 7 on the support 4, be equipped with reference column 8 in the pilot hole 7, be arranged with spring 9 on the reference column 8, wherein an end of reference column 8 passes the pilot hole 7 of support 4 and fixes by screw thread and computer main board, thereby radiating fin group 2 is fixed on the computer main board.Pedestal 1 passes support 4 and forms boss 10, and boss 10 is stuck on the support 4.

Because the hardness height of copper or aluminium alloy, be not easy to damage, can manufacture radiating fin than complicated shape, big to reach area of dissipation, the purpose that ventilation effect is good; And graphite composite material is more much lower than the price of copper and aluminium, have the low characteristics of cost, and the pedestal of making by graphite composite material 1, heat conduction is fast, radiating efficiency is high, in light weight, so it is the pedestal 1 that the compound substance of matrix is made that the utility model is selected for use with graphite, it can pass to radiating fin group 2 to the heat on the CPU apace apace.In sum, the utility model is the advantage that combines copper or aluminium alloy, graphite composite material, radiating rate is fast, cooling-down effect is remarkable, in light weight, cost is low.

The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
