So the distance between the fan cover and the fan is smaller on the top and larger at the bottom.

Description

Heat spreader structures

Technical field

The utility model relates to a kind of heat spreader structures, and particularly a kind of fan by the high inclination setting reaches the heat spreader structures that disperses peripheral heat.

Background technology

Radiator forms proportional relationship more and more sooner to the importance and the operational speed of a computer of electronic heating component, and is more and more longer when the computed time, and the temperature that central processing unit (CPU) produces also is more and more higher certainly.The high temperature of central processing unit maybe can be lowered the temperature by the internal heat dissipating of utilization own if can be accepted in the scope, and to maintain in the acceptable temperature value, this temperature factor promptly no longer is the emphasis of the required consideration of product.But the fact is often really not so, rises so the spare part of most designer by external particular design reduces the temperature of processor, and in can received number range, all be normal to make computer operating with the high temperature of keeping central processing unit.

Yet modal is to install radiating subassembly (Heat SinkAssembly) on electronic heating component additional, but the multi-form heat sinking benefit that radiating subassembly showed often has diversity.As shown in Figure 1, prior art makes central processing unit 3a top paste mutually with the heat conducting seat 1a that is provided with radiating fin 10a, the heat energy that is produced when working with crossing central processor 3a is to radiating fin 10a, or run through the heat conduction that heat pipe 11a assist process that each radiating fin 10a is set is clamored, be arranged on the side of radiating fin 10a at last with fan 2a, utilize laterally disposed fan 2a to force blows cold air, to reach the effect of heat radiation.

In addition, the problem that should be noted that is: the electronics spare part that is positioned at around this radiator forms another high thermal source because of central processing unit and the heat energy of itself, if can't dispel the heat in real time, then may cause the problem of defective chip or electronic heating component itself.For solving the heat dissipation problem of central processing unit and peripheral spare part, many heat sink technology have been developed, disclose a kind of " heat abstractor " in the prior art, it comprises fin, load bearing seat and fan, the centrifugal fan by set position of this fan and application to electronic component and radiating fin respectively blows cold air to reach radiating effect.But, the heat abstractor of this type is implemented at notebook computer.In addition, this fan one side is air can see through state, and only with this side fin is blown, and the course of estimating the air-flow that is produced by this side can't influence radiating efficiency to all fin heat radiations.

In view of this, the utility model is created artificial the improvement and is straightened one out and eased out his anxiety the above-mentioned defective of determining, and through concentrating on studies and cooperating the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.

The utility model content

Main purpose of the present utility model, being to provide a kind of heat spreader structures, it is except providing the basic radiating requirements of electronic heating component, further the ambient temperature of this electronic heating component periphery effectively can be reduced, especially can dispel the heat at the less important thermals source such as transistor that are positioned at this electronic heating component periphery.

To achieve the above object, the utility model provides a kind of heat spreader structures, the fan that comprises radiator structure and be positioned at this radiator structure one side; Wherein, between this radiator structure and fan, be provided with a plurality of gradient bed hedgehopping spares, bed hedgehopping spare has two kinds of different height at least, and height the higher person is located at the place, below between fan guard and the fan, the height junior then is located at the place, top between fan guard and the fan, so that the distance that this fan guard and fan are asked each other is up-narrow and down-wide tilted configuration.
