In some embodiments, heat-conducting layer thickness is 0.07mm～0.15mm.Its beneficial effect is that such thickness can reach better thermal diffusivity, and has better flexibility.
In some embodiments, the material of insulating barrier is PET, and thickness is 0.03mm～0.05mm.Its beneficial effect is, the insulating properties of PET is more stable, and changes thickness and also increased its sanction property.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fin of the utility model one execution mode.
Embodiment
Below in conjunction with accompanying drawing, utility model is described in further detail.
Fig. 1 has schematically shown the fin according to a kind of execution mode of the present utility model.As shown in the figure, this fin comprises the base material 1 that can compress, the heat-conducting layer 2 that is coated on base material 1 surrounding and for the first adhesive layer 4 of fixing substrate 1 and heat-conducting layer 2, described base material 1 is PU foamed cotton.Be specially and provide as required a foamed cotton as base material 1, because the compression ratio of foamed cotton is 20%～30%, can greatly reduce the volume of base material 1.And in order to reach the effect of heat radiation, so need to be coated one deck heat-conducting layer 2 in the surrounding of base material 1 foamed cotton.But because base material 1 and heat-conducting layer 2 need to be fixed together, become as a whole, so also need first adhesive layer 4, the first adhesive layers 4 that base material 1 and heat-conducting layer 2 can be fixed together to be located between base material 1 and heat-conducting layer 2, base material 1 and heat-conducting layer 2 be fixed together.The major part of using heat radiation due to needs is electrical type device, and electrical type device most of this series products need good insulating properties.And most thermal conductivity material all generally has conductivity, so just need to take into account the characteristic of insulation when guaranteeing heat conduction.So heat-conducting layer 2 outsides are also coated with insulating barrier 3, insulating barrier 3 is fixed on heat-conducting layer 2 outsides by the second adhesive layer 5.Adopting the second adhesive layer 5 is because insulating barrier 3 and heat-conducting layer 2 are two relatively independent individualities, both cannot fix bonding, need to use other and there is fusible material both are fixedly bonded together, so the second adhesive layer 5 is set herein, can effectively insulating barrier 3 and heat-conducting layer 2 be fixedly bonded together.In order to make heat-conducting effect better, so heat-conducting layer 2 is graphite or heat-conducting metal.Adopting graphite is heat-conducting layer 2, because graphite is nonmetalloid, still but has the conduction of metal material, and heat conductivility, also has the plasticity that organic plastics is the same, so adopt graphite to be used as the better effects if that heat-conducting layer 2 can make fin.But, because some are special, need heat-conducting layers 2 to adopt heat-conducting metals, so just need to adopt the metal of good heat dispersion performance, as copper sheet or aluminium foil wheat are drawn.In order to guarantee the plasticity of fin, heat-conducting layer 2 thickness are 0.07mm～0.15mm.Its beneficial effect is that such thickness can reach better thermal diffusivity, and has better flexibility.The material of insulating film layer (3) is PET, and thickness is 0.03mm～0.05mm.Its beneficial effect is, the insulating properties of PET is more stable, and changes thickness and also increased its sanction property.
The preparation method of fin of the present utility model: comprise the steps:
Heat-conducting layer 2 is provided, and heat-conducting layer 2 is graphite linings or heat-conducting metal layer; The first adhesive layer 4 is provided, on heat-conducting layer 2, applies the first adhesive layer 4; Base material 1 is provided, base material 1 is positioned on the first adhesive layer 4 and is heated, in heating, the first adhesive layer 4 is coated on to base material 1 outside, make heat-conducting layer 2 be coated on base material 1 surrounding by the first adhesive layer 4.Insulating barrier 3 is provided, on insulating barrier 3, applies the second adhesive layer 5.Again the insulating barrier 3 that is coated with the second adhesive layer 5 is coated on to the outside of heat-conducting layer 2, makes insulating barrier 3 be coated on heat-conducting layer 2 outsides by the second adhesive layer 5.Wherein graphite linings is synthetic graphite sheet or uniform native graphite bisque.The first adhesive layer 4 is hot melt adhesive layer, and the second adhesive layer 5 is acrylic glue-line.
Whole coated process is is PU foamed cotton by base material 1, being placed on and being coated with the first adhesive layer 4 is that the heat-conducting layer 2 of PUR is in graphite linings, and PU foamed cotton contacts with PUR, now graphite linings is wrapped to PU foamed cotton heats simultaneously, now PUR, because thermodynamic activity can be bonded together PU foamed cotton and graphite linings, finally carries out cooling fixing again.Utilize preparation method of the present utility model to prepare fin, manufacturing processes is simple, has improved production efficiency, with low cost, and the product obtaining has good electromagnetic wave shielding.
Above-described is only execution modes more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to the protection range of utility model.
