Title: Clad casing for laptop computers and the like

Abstract: Disclosed is a casing for an electronic device which includes a heat dissipation layer, inner and outer insulative layers along either side of the heat dissipation layer, and a heat pipe which has a portion in thermal-transfer contact with the heat dissipation layer. The heat dissipation layer has a thermal conductivity in a first range whereas the insulative layers have a thermal conductivity in a different, lower range. Preferably, the inner layer is either thicker than the outer layer, has a lower thermal conductivity than the outer layer, or both. Vent holes can be provided through the heat dissipation layer, and, if so, the holes are preferably covered by either the inner or outer layers. Only a portion of the casing need have the foregoing heat dissipation layer, inner and outer insulative layers, and heat pipe.
