Application of thermal conductivity of
carbon nano-balls coated fabric products, in addition to
electromagnetic wave shielding function, can also both thermal
conductivity, heat and fire functions. With Nano Carbon Ball / PU
polymer resin, a small amount can add an effect, we can maintain
physical properties of rubber material to form a good follow-up of
paste. With optical microscopy conductive fabric membrane, the surface
of metal evenly distributed in the polyester fibers to form a good
conductive channel, however, woven fabric membrane to produce a
staggered manner pores, these pores become the largest in the thermal
conductivity on thermal resistance. The ball through the functional
group of carbon nano-modification, the so easy to spread PU resin, and
in conjunction with the turn of the formation of a homogeneous
nano-copolymerization resin, uniform coating on the conductive cloth to
patch up the cracks, to reach dense cover with the paste performance
results. Finally enable the thermal product thermal conductivity cloth
over 2.85W/mK, and has 6 ° C cooling effect. Thermal conductive fabric
membrane can be designed for high performance thermal conductivity of
films, will be hot to the rapid spread of aluminum cooling frame,
re-use of natural air convection heat dissipation. Although the thermal
conductivity of aluminum heat sink worse than copper, but copper prices
soaring in recent years, and lighter than copper and aluminum has the
advantage of good weather. If with cheap aluminum frame with high
thermal conductivity of thermal interface material and solve hot and
concentration of heat dissipation will be able to replace the copper to
achieve the cost reduction benefits.
