Description of the invention: 1. [Technical field to which the invention belongs] The present invention relates to a heat sink and heat sink, which are used for CPUs, power transistors, etc. of electronic products such as notebook computers or mobile phones. Heat generated in semiconductor components, plasma display panels, plasma microprocessors, silicon microprocessors, light emitting diodes (LEDs), or organic light emitting diodes (OLEDs) such as plasma televisions is effectively dissipated. 2. [Previous Technology] In recent years, various electronic products such as notebook computers or mobile phones used in our daily life have become increasingly high-performance and compact. However, Ik is focusing on the high-performance and miniaturization of such electronic products, and the semiconductor components assembled in them are also continuously moving towards higher capacity and intensification. Therefore, the > heat generation in electronic products will also follow Increased greatly. White main technical towels, such as laptop products such as laptops, are mostly the thermal energy of future parts. After being transmitted through copper or metal plates with good thermal conductivity, heat transfer (ΐϊ) or heat sinks are transmitted. And then dissipate it to the outside for heat dissipation. However, please replace it with a metal sheet. For example, the reason for the replacement of the metal sheet is that the graphite sheet can be used as a feature in Γ ' The layered substrate composed of the circuit substrates of the layers is interspersed with the substrates, etc. The heat-dissipating film, or the system of the plasma display panel in the plasma television; ^^ == is, there is a problem with the film 'That is because the structure of a layer of humans is obstructed'. Therefore, although the molecules in the plane direction of each layer are connected together through 5 200529394, the distance perpendicular to the plane direction intersects _ is the combination of intermolecular forces Weaker, so capacity Generating layer in addition to the surface direction ίί: AC = low thermal conductivity = II thereto a sufficient heat radiation effect can not be obtained direction), and therefore sometimes other, outside on other known technology, there are - what kind of loose sheets,

With this type of heat sink, the heat dissipation efficiency of the original heat sink with a lower heat dissipation efficiency can be transferred with respect to the vertical S ^, iSi rate '. Xu's promotion ’but the machine has no bottom to solve A ’s biggest disadvantage, the problem of peeling between layers. -/, Take a big handle ", in general, the heat sink is formed by shouting is copper, etc., the heat sink made of this all-generic material has a limited heat dissipation effect. The increase in trough setting and the reduction in the appearance of the face are more significant and cannot be adequately addressed.

When the thickness of the stacked mesh is more than 1.5, it is easy to produce and may be 50% off; However, the direction of the hot-shot ejector is lowered, and the thickness of the expanded graphite sheet is particularly ideal. If the thermal conductivity is not satisfied with the strength of graphite ㈣, the flexibility will be reduced. No matter what ratio it is, if it exceeds 2.2 g / an3, it will form the metal wire of the mesh 合. The thermal conductivity is preferred. For example, in the case of copper and steel, high + rust steel, platinum, titanium, Shao, Inco Record 200529394 (I_el), monel metal, nickel, etc. are used, but not limited to these metals. The thickness of the metal wire constituting the reticulate body (2) in doubt may be appropriately set according to the puffstone. For example, if the thickness of the dilatant stone is set to the center of i ^ 0 2 = 〇 ~ G · 5, it is better to make the diameter ratio ratio. Specifically, the thickness of the metal wire is' better to use a thickness of approximately 〇. 〇5 ~ 〇 · 15 mm or so. · There is no restriction on the thickness (size) of the reticulate body, as long as it is set to > < within the area of 10 legs, there are about 5 to 40 patterns with the same pattern. 1) If the mesh size is too large, the thermal conductivity in the thickness direction will be lost if the effect of avoiding interlayer peeling is lost. Conversely, if M is increased, the flexibility will be reduced. In any case, the mesh body ( 2) As for the better case, as shown in Fig. 3, it is better to make gold to the plate after the work: In addition, as shown in FIG. 4, the thread may be made into a # shape after weaving. In addition, the scales are prepared by guarding or weaving, and any method may be used as long as the wire can be made into a sheet-like network. In terms of weaving and processing, weft weaving and weaving can be performed using flat stitch, rib weave, double-reverse set circle weaving, western thread weaving, single hoisting weave, double hoisting weaving, weaving, weaving, weaving, etc .; or It is a method of warp knitting and weaving such as single-flow stitching, plain weave, and double-sweet plum], weaving, mesh, and Milan. The "method" is a method of weaving a metal wire and adding I as a mesh body ", so that the Chen body can be made softer and its thickness can be reduced. Therefore, it can be made into a very soft A-sheet door. In terms of weaving processing, plain weave, twill weave, forged weave, evening re-weave, leno weave, and weave weave can be used. This, in this way, the way of weaving the metal wire as a mesh body 'can get the combination between the metal wire and the metal wire in the mesh body 12 200529394 on the front f back both sides, both Although the method of stacking stacked stromatolites and ink flakes is not limited, a preferred method 5 is an integrated rolling process. Fig. 5 is a schematic cross-sectional view of a radiating fin formed by laminating a mesh body ⑵ by a rolling process. It is suspected that the graphite sheet ⑴; and the front face: the swelled graphite sheet ⑴ is almost the same-plane. In the meantime, the shape = '= the general body and the expanded graphite sheet 丨 丨 ink> U1) is completely the same-flat ϋ, # towel, although the mesh body ⑵ and the expanded graphite sheet ⑴ are protruding from the front The… + 'phase can also be expanded by using the reticulate body. It is 4 ° larger, but the best way is not to overburden the expanded stone by rolling, so that it can be firmly clamped on the front and back of the stone. Because the metal wire's network is very good in thermal conductivity through the heat conduction system, that is, it conducts heat in the direction of the direction, so in the thickness direction, and / or 'etc: pieces: at t two, and the back two system can be at Expanded graphite sheet ⑴ The front sheet ⑴ is rolled and integrated: Think of one side, a stack of several sheets, a mesh body 与, and the expanded graphite sheet 面 ^ 13 200529394 In the example shown in Figure 6, the front side It is the same as the back, but it can also be laminated more than 3 pieces. At the same time, the same number of mesh bodies (for example, 2 pieces and 3 pieces, the March face and the moon face are heated by using a method not placed in a heating furnace, respectively). The exothermic sheet composed of () pounds can be heated at a temperature of more than 30 (rc, more J = 〇Γ °° ... In addition, the better processing | good sublimation ====== expansion alone In the case of graphite, it is assumed that S is dissatisfied with the formation of the reticulate body, and j). If the structure is better, _ is the configuration type of the inert environment without lying on the heat treatment environment. If the layer will be laminated by rolling, it will move strongly and make the atom move beyond the graphite layer. And ΓΓ produces a thermochemical reaction with the carbon atoms of Ϊ, forming a diffusion bond. The heat transfer in the direction can be greatly improved, and the thickness (2) of the front structure is used.

The lamination-body method does not include the special di-body (2) system of lamination-and-rolling treatment, or the expansion stone black = limit, and the rolling roller can be used to be almost the same-plane. In addition, the design of the front of the cymbal can also be adopted. However, the better formula 3 is that the amount of protrusion of the expanded graphite sheet (1) should not be too large. However, the cross-sectional view of Fig. 16 200529394 shows the state where the mesh body ⑵ is exposed from the full side of the expanded graphite sheet ⑴. In the heat sink shown in FIG. 12, the above-mentioned expanded graphite sheet ⑴ is composed of two pieces of stone ′. Between the two expanded graphite sheets ⑴, an intermediate intermediate ⑸ made of metal wire is sandwiched. Then, here, the front and back surfaces of the structure formed by the expanded graphite sheet ⑴ and the net-like intermediate body 网 are provided in a laminated body. For the lateral intermediate ⑸, the same structure as that of the reticulate ⑵ is used. In the example shown in the figure, although the expanded graphite sheet ⑴ is set to 2 pieces, the GGr is set to 3 or more pieces.

The example shown in the figure shows that in the heat sink sheet shown in Fig. 12, the expanded graphite sheet ⑴, the mesh body ⑵, and the netting are laminated and integrated. Although the method of lamination integration is not particularly limited, it is a method in which a roll is rolled, for example, by a rolling roller or the like. By this rolling treatment, the front and back sides of the reticulated body 埋 and the reticulated expanded graphite sheet ⑴ are formed; and the expanded stone S) 'reticulated body ⑵ and the front of the reticulated intermediate ⑸ are presented.

In addition, although the mesh body (2) and the metal foil (6) can be protruded from the surface of the expanded graphite sheet 0) by two, the amount of protrusion is preferably not too large. However, in the cross-sectional view of FIG. 13 (1)), the mesh body (2) is completely exposed from the front of the expanded graphite sheet (1), and the protrusions of the metal foil (6) are omitted. ^ In the heat sink shown in Figures 11 to 13, at least one of the front and back sides of the expanded graphite sheet (1) can be used.
