Heat dissipation housing for AC power adapter
The present disclosure provides a heat dissipation housing for an AC power adapter, including a housing and a heat sink disposed on an inner surface of the housing, and integrally formed with the housing. The heat sink includes an upper surface which is in close contact with the housing, and a lower surface which is exposed to the inside of the heat dissipation housing. The heat sink includes at least one securing structure which is formed by the upper surface of the heat sink.
1 . An AC power adapter, comprising:
a heat dissipation housing, comprising:
a housing; and
a heat sink disposed on an inner surface of the housing, and integrally formed with the housing; and
an inner heat sink,
wherein the heat sink comprises an upper surface which is in contact with the housing, and a lower surface which is exposed to an inside of the heat dissipation housing,
wherein the heat sink comprises at least one securing structure which is formed by the upper surface of the heat sink,
wherein the heat sink is embedded into at least a portion of the inner surface of the housing,
wherein the entire heat sink is disposed inside the housing,
wherein the housing is made of plastic,
wherein the heat sink is integrally formed with the housing by injection molding,
wherein the inner heat sink has a tubular shape, and is integrally formed or formed by buckling two U-shaped heat sinks, and
wherein one or more surfaces of the inner heat sink is in direct contact with the lower surface of the heat sink of the heat dissipation housing.
2 . The AC power adapter according to claim 1 , wherein the at least one securing structure is formed in a barb structure.
3 . The AC power adapter according to claim 2 , wherein the barb structure comprises at least one of a T-shaped structure, an inverted trapezoidal structure, or a rod-shaped structure at a certain angle to a surface of the heat sink.
4 . The AC power adapter according to claim 1 , wherein the heat sink is disposed on all or part of the inner surface of the housing.
5 . The AC power adapter according to claim 1 , wherein the heat sink has a tubular shape.
6 . The AC power adapter according to claim 1 , wherein the heat sink is made of copper or aluminum.
7 . The AC power adapter according to claim 1 , further comprising:
a power supply assembly disposed inside a cavity formed by the heat dissipation housing, and comprising a circuit board and an electronic element arranged on the circuit board, and
wherein the inner heat sink disposed on a periphery of the power supply assembly and secured to the power supply assembly.
8 . The AC power adapter according to claim 7 , wherein the inner heat sink comprises one or more inner heat sinks, each being disposed corresponding to a surface of the power supply assembly.
9 . The AC power adapter according to claim 7 , wherein an insulating part is disposed between the inner heat sink and the power supply assembly.
