(heat abstractor of embodiment 1, consumer electronics)
See Fig. 1, the heat abstractor of the consumer electronics of the present embodiment (hereinafter to be referred as heat abstractor) comprises the first two-sided tape 52, the 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 the second two-sided tapes 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 by metallic plate punch forming or metal, squeezes type and cut again by removing metallic support rough and that anti-oxidant treatment makes by line.The present embodiment adopts the lower plastic stent of manufacturing cost.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 piece, and graphite heat conducting block is by bulk graphite block, after laser cutting, to be removed rough processing to make; Metal heat-conducting piece is by metallic plate punch forming or metal, to squeeze type after removing rough and anti-oxidant treatment, to make by line cutting again.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.
The first graphite radiating film 51 and the second graphite radiating film 1 are all to be cut and made by graphite radiating pleurodiaphragmatic in terspace material, and graphite radiating film is all a kind of novel heat conduction and heat radiation materials, are divided into expandable graphite sheet and artificial high conductive graphite film.Expandable graphite sheet is to adopt high purity graphite scale to form by chemical treatment and through high-temperature expansion rolling, thickness 0.03 to 1.0mm, plane conductive coefficient is at 200 to 600W/m K, the graphite purity of expandable graphite sheet is higher, plane conductive coefficient is better, and its vertical direction conductive coefficient is 5 to 20W/m K; Artificial high conductive graphite film makes, has the graphite film of graphite-structure with high directed macromolecule thin film containing carbon material through special process, thickness 0.01 to 0.1mm, plane conductive coefficient is at 800 to 1900W/m K, the horizontal direction structure of artificial high conductive graphite film is tightr, its conductive coefficient is higher, and its vertical direction conductive coefficient is 10 to 55W/m K.The present embodiment adopts the artificial high conductive graphite film of the 0.025mm thickness of Jiangsu legend Science and Technology Ltd. production, and 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.
