Abstract
The utility model relates to a folding heat radiation device which comprises a heat radiation sheet group (10). The utility model is characterized in that the heat radiation sheet group (10) comprises heat radiation sheets (1) which are orderly arrayed, and the curved rules of the heat radiation sheets are identical. The utility model provides the folding heat radiation device used for inner limit space of a machine shell, and the device has little space occupation in the compact space, such as a machine shell of a notebook computer. The utility model has the advantages that the heat radiation area of the utility model is larger than the heat radiation area of a flat heat radiation device, and the heat radiation efficiency is high.
Description
Technical field
The utility model belongs to heat abstractor, belongs to the efficient radiating apparatus that is applicable to compact CyberSpace especially.
Background technology
Develop rapidly along with science and technology, transistor, integrated circuit and central processing unit operating rate in the computer chassis are more and more faster, the incident high temperature that self is produced causes the damage of components and parts easily, for example comprises the damage of the components and parts of silicon wafer.Particularly in the tight space under the high integration condition, for example: notebook computer, mobile PC because its narrow space is limited, make radiating and cooling become great problem.The heat radiator that is used for heating radiator in the various computer is based on straight, want the radiating effect that reaches predetermined, need to increase the length and the wide size of straight heat radiator, this necessity of making use of momentum takies the space of cabinet, and existing flat type heat dissipation equipment can't solve the heat dissipation problem in the portable computer small space.
Summary of the invention
The utility model is to avoid the above-mentioned weak point of prior art to propose a kind of collapsible heat abstractor that is used for the cabinet inside finite space, this device takes up room seldom in tight space such as computer notebook casing, its area of dissipation is bigger than flat type heat dissipation equipment, the radiating efficiency height, effect is obvious.
The technical problems to be solved in the utility model is the surface area that how to increase heat radiator in tight space, thereby improves radiating efficiency.
The method of the utility model technical solution problem is to use the identical heat radiator of crooked rule, form groups of fins, it is long-pending to make the heat radiator of same surface area take less plane, and that the groups of fins occupation space increases is few, thereby increases considerably efficiently radiates heat area in the unit space.
The purpose of this utility model can reach like this:
A kind of collapsible heat abstractor comprises groups of fins, and especially described groups of fins comprises the identical heat radiator of crooked rule of orderly arrangement.
The beneficial effects of the utility model are to take up room seldom in tight space such as computer notebook casing, and its area of dissipation is bigger than flat type heat dissipation equipment, the radiating efficiency height.
Description of drawings
Fig. 1 is the one-piece construction figure of the collapsible heat abstractor of the utility model;
Fig. 2 is the structural drawing of described collapsible heat abstractor surface blending type heat radiator;
Fig. 3 is described heat radiator flattened state synoptic diagram.
Embodiment describes embodiment of the present utility model in detail below in conjunction with accompanying drawing.
A kind of collapsible heat abstractor comprises groups of fins 10, and especially described groups of fins 10 comprises the heat radiator 1 that the crooked rule of orderly arrangement is identical.
Described heat radiator 1 is the multiple-unit flexure type, is provided with a plurality of turnover grooves 11.
Among some embodiment, described heat radiator 1 is for facing the knuckle type directly, and described turnover groove 11 is corner angle.Among other embodiment, described heat radiator 1 can be the surface blending type, and described turnover groove 11 is the garden arc.
Described collapsible heat abstractor also comprises thermal conductive metal plate 20, and its surface is affixed with described groups of fins 10 bottom fold planes.Described thermal conductive metal plate 20 bottoms are provided with level and smooth heating surface.
Described groups of fins 10 1 sides are connected with radiator fan 30.
Described heat radiator 1 is heat-conducting metal material copper or aluminium, and its open and flat length L 1 is 1.5 times of crooked back heat radiator 1 ' length L 2.
In the practicality, the groups of fins 10 of described collapsible heat abstractor is welded or is riveted on heat-conducting metal material copper coin or the aluminium sheet, this thermal conductive metal plate 20 with level and smooth heating surface near CPU 40, so that the heat of CPU40 is through sheet metal 20 guiding groups of fins 10, and distinguished and admirable the spreading in the air that is produced by radiator fan 30.Because the orderly bend alignment of heat radiator 1 can increase the heat exchange area between distinguished and admirable and the heat radiator 1 in the space of compactness, improve radiating efficiency, help precision equipment miniaturizations such as computer.
