Abstract
The utility model relates to an aluminium-carbon heat-conducting insulating composite foil, which comprises an insulating layer, an aluminium foil heat-conducting layer, a carbon heat-conducting layer and an adhesive layer. The adhesive layer is arranged under the carbon heat-conducting layer of the aluminium-carbon heat-conducting insulating composite foil, a release material layer is arranged on the bottom of the adhesive layer, and the insulating layer comprises a bottom adhesive layer which is used for sticking the aluminium foil heat-conducting layer. The aluminium-carbon heat-conducting insulating composite foil is used for rapidly conducting the heat source in an electronic device, the heat source in the electronic device is generated by a chip and gathered at a certain point, the heat gathered at the point can be rapidly conducted onto the aluminium-carbon heat-conducting insulating composite foil because the aluminium-carbon heat-conducting insulating composite foil has extremely high thermal conductivity in X, Y and Z directions, and therefore the heat conducting is changed from a point to a surface, and the temperature of the heat source in the electronic device is rapidly decreased. Since the insulating layer is arranged on the top of the aluminium foil heat-conducting layer of the aluminium-carbon heat-conducting insulating composite foil, the surface is insulative during use.
