Claim of US Patent No. 10,462,944

1. A wave absorbing heat dissipation structure, adapted to absorb electromagnetic waves of an electronic component and dissipating heat energy of the electronic component, the wave absorbing heat dissipation structure comprising:a wave absorbing heat dissipation layer, adapted to be arranged on the electronic component, having a first surface and a second surface with positions opposite to each other, the first surface covering the electronic device, wherein the wave absorbing heat dissipation layer further comprises a wave absorbing portion and a heat dissipation portion; and
a metal film, covering the second surface;
wherein, the wave absorbing heat dissipation layer is adapted to absorb the electromagnetic waves and transmit the heat energy, and the metal film is adapted to reflect the electromagnetic waves and dissipate the heat energy;
wherein the first surface further comprises a third surface and a fourth surface that are adjacent, the third surface and the fourth surface adapted to cover the electronic component, the second surface further comprises a fifth surface and a sixth surface, the metal film covers the fifth surface and the sixth surface, the wave absorbing portion has the third surface of the first surface and the fifth surface of the second surface, a through hole is formed between the third surface and the fifth surface, and the heat dissipation portion is arranged in the through hole and has the fourth surface and the sixth surface; and
wherein the wave absorbing portion is a polymer material comprising electromagnetic absorbing particles, the heat dissipation portion is a polymer material comprising heat dissipating particles, and compositions of the wave absorbing portion and the heat dissipation portion are different.
