Claim 0:
1. An electronic device, comprising:
a casing;
an electronic structure disposed in the casing, wherein a surface of the electronic structure has at least one heat source element; and
an aluminum or copper foil heat dissipator that is a 3D aluminum or copper foil structure formed by stamping and comprises a bottom and a surrounding portion connected around a periphery of the bottom, wherein a 3D space is formed between the bottom and the surrounding portion; the bottom is thermal conductively coupled to the at least one heat source element; at least one part of a surface of the aluminum or copper foil heat dissipator is thermal conductively coupled to an inner surface of the casing;
wherein the bottom has at least one protruding portion protruding toward the at least one heat source element and forming a contact surface at a front side of the at least one protruding portion facing the at least one heat source element; a thermal pad is disposed on the contact surface to be thermal conductively coupled to the at least one heat source element;
wherein the inner surface of the casing has at least one support protrusion inserted into the at least one protruding portion to support the at least one protruding portion; a surface of the at least one protruding portion is coated with a heat conductive glue to be thermal conductively coupled to the at least one support protrusion.
