Embodiment
The utility model, when carrying out orientation and describing, is described with orientation shown in Fig. 1, and the orientation up and down in figure is also up and down in the de-scription, and the orientation of picture in picture face court of institute is front, and the orientation deviating from drawing is rear.
(embodiment 1, heat abstractor)
See Fig. 1, the heat abstractor (hereinafter referred to as heat abstractor) of the present embodiment comprises two-sided tape 52, first graphite radiating film 51, release film 6 and at least one radiator structure part 100.
See Fig. 2, radiator structure part 100 comprises the second graphite radiating film 1,2 heat-conducting silica gel sheets 2, support 3 and heat-conducting blocks 4.
See Fig. 3, support 3 is by the plastic stent of plastic pellet injection mo(u)lding or shaping or metal to squeeze after type through Linear cut again by except rough and that anti-oxidant treatment is obtained metallic support by stamped metal sheets.The present embodiment adopts the plastic stent that manufacturing cost is lower.Support 3 is overall rounded radial, and support 3 is provided with the square center through hole 31 of up/down perforation.The thickness of support 3 is 3 to 5mm.
See Fig. 1 to Fig. 3, heat-conducting block 4 is graphite heat conducting block or metal heat-conducting block, and graphite heat conducting block after laser cutting, removes rough process by bulk graphite block to make; Metal heat-conducting block be shaping by stamped metal sheets or metal squeeze type after through Linear cut again by making after rough and anti-oxidant treatment.The shape of heat-conducting block 4 is corresponding with the shape of the center through hole 31 of support 3, and the thickness of heat-conducting block 4 is corresponding with the thickness of support 3.
First graphite radiating film 51 and the second graphite radiating film 1 are all cut by graphite radiating film raw material to make, and graphite radiating film is all a kind of novel heat conduction and heat radiation materials, is divided into expandable graphite sheet and artificial high conduction graphite film.Expandable graphite sheet adopts high purity graphite scale by chemical treatment and forms through high-temperature expansion rolling, thickness is at 0.03 to 1.0mm, and plane thermal conductivity is at 200 to 600W/mK, and the graphite purity of expandable graphite sheet is higher, plane thermal conductivity is better, and its vertical direction conductive coefficient is 5 to 20W/mK; The high directed macromolecule thin film containing carbon material of artificial high conduction graphite film obtains, has the graphite film of graphite-structure through special process, thickness is at 0.01 to 0.1mm, plane thermal conductivity is at 800 to 1900W/mK, the horizontal direction structure of artificial high conduction graphite film is tightr, its conductive coefficient is higher, and its vertical direction conductive coefficient is 10 to 55W/mK.The artificial high conduction graphite film of the 0.025mm thickness that the present embodiment adopts Jiangsu legend Science and Technology Ltd. to produce, conductive coefficient is 1353W/M/K.The shape of the first graphite radiating film 51 and the second graphite radiating film 1 is all corresponding with the peripheral shape on the upper and lower surface of support 3.
Two-sided tape 52 is divided into the adhesive tape containing base material and the adhesive tape without base material.Two-sided tape containing base material is all adhesive tapes of making of glue coating on the two sides of plastic film, and namely base material is plastic film, and this two-sided tape in use base material can not be separated with glue; Two-sided tape without base material is the adhesive tape that directly glue coating is made on release film 6, and this adhesive tape in use needs to peel off release film 6, becomes pure glue adhesive tape.The thickness of two-sided tape 52 and heat-conducting silica gel sheet 2 is 0.005 to 0.1mm, select the two-sided tape of thinner thickness mainly because the radiating effect impact of thin adhesive tape on the first graphite radiating film 51 and the second graphite radiating film 1 is little, if two-sided tape is too thick, the two-sided tape 52 contacted with electronic product pyrotoxin CPU at first just can not transfer heat to rapidly the heat that the first graphite radiating film 51 is accumulated on CPU will be increased, thus affects radiating effect; The two-sided tape of thinner thickness can reduce the gross thickness of design of electronic products in addition, is more conducive to Fashion Design.In the present embodiment, the thickness of two-sided tape 52 and heat-conducting silica gel sheet 2 is 0.01mm.And the shape of two-sided tape 52 is corresponding with the shape of the contact-making surface of electronic product pyrotoxin such as CPU, the shape of heat-conducting silica gel sheet 2 is consistent with the shape of the second graphite radiating film 1.
See Fig. 2, the shape heat-conducting silica gel sheet corresponding with the underside shape of support 32 is stained with at the lower surface of support 3, to be bonded on the heat-conducting silica gel sheet 2 on the lower surface of support 3 by its lower surface in the center through hole 31 of heat-conducting block 4 Stent Implantation 3 from the top down, then be stained with on another heat-conducting silica gel sheet 2 at the upper surface of support 3, then heat-conducting block 4 is fixed in the center through hole 31 of support 3 in the vertical direction, second graphite radiating film 1 by the heat-conducting silica gel sheet 2 on the upper surface of its lower surface and support 3 closely compound be pasted together, thus composition radiator structure part 100.
See Fig. 1, in the present embodiment, the quantity of radiator structure part 100 is 3, 3 radiator structure parts 100 are from top to bottom pasted successively and links together, specifically, first radiator structure part 100 is alignd by the heat-conducting silica gel sheet 2 of its bottom with the second graphite radiating film 1 of the top of second radiator structure part 100 and be closely pasted together, second radiator structure part 100 is alignd by the second graphite radiating film 1 of the heat-conducting silica gel sheet 2 of its bottom with the top of the 3rd radiator structure part 100 and be closely pasted together, then the first graphite radiating film 51 is alignd by the heat-conducting silica gel sheet 2 of its upper surface with the bottom of the 3rd radiator structure part 100 and is closely pasted together, then two-sided tape 52 is sticked in the above-mentioned lower surface central authorities being positioned at the first graphite radiating film 51 of bottom, the lower surface of two-sided tape 52 is covered with release film 6.
(application examples 1, electronic product)
See Fig. 4, should the electronic product of use-case comprise mainboard 300, the CPU(central processing unit be arranged on mainboard 300) 200 and the heat abstractor that obtained by embodiment 1.Be pasted on the CPU200(central processing unit of corresponding electronic product after being peeled off by release film 6 on the two-sided tape 52 being positioned at bottom of the heat abstractor obtained by embodiment 1 by two-sided tape 52) or other parts that need dispel the heat on.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to spirit institute's apparent change of extending out of the present utility model or change and are still among protection range of the present utility model.
