Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power supply heat dissipation, in particular to an isolation heat dissipation structure and a power adapter thereof. Background Art
[0002] The power adapter needs to meet the requirements of safety regulations. Taking the desktop power adapter as an example, it needs to meet the requirements of IEC-62368. Specifically, when the AC socket of the power adapter is at a room temperature of 35°C and full-load output within the full input voltage range, the temperature rise of the AC socket should be less than 70°C. Usually, the temperature rise of the AC socket of a high-power power adapter (≥300W) is relatively large, and it is relatively difficult to meet the safety regulation requirements. The heat source comes from the PCBA, and the self-heating of the metal PIN of the AC socket caused by the contact impedance between the power cord and the metal PIN of the AC socket. The safety regulation requires that the temperature of the AC socket does not exceed 70°C when the power adapter is working. The existing method is to reduce the heat transferred from the PCBA to the AC socket by adjusting the distance between the PCBA and the AC socket or by removing the heat dissipation component near the AC socket. However, the improvement effect of this method is limited, and removing the heat dissipation component will reduce the heat dissipation of the PCBA itself and the heat dissipation effect of the PCBA itself. Summary of the Utility Model
[0003] The purpose of the utility model is to provide an isolation heat dissipation structure and a power adapter thereof, aiming to solve the technical problem of excessive temperature rise of the AC socket of the power adapter in the related art.
[0004] To solve the above problems, according to one aspect of the present application, an embodiment of the utility model provides an isolation heat dissipation structure applied to the heat dissipation of a power adapter. The power adapter includes a housing, an AC socket, and a control board. The AC socket is electrically connected to the control board, and the control board is disposed inside the housing.

[0005] In some embodiments, the housing includes a first half-shell and a second half-shell that are snap-fitted together. A first opening is provided on the first half-shell, and a part of the AC socket is clamped at the first opening. A second opening is provided on the second half-shell, and a part of the AC socket is clamped at the second opening. The isolation structure includes an isolation board constructed on the second half-shell and located on both sides of the AC socket and between the AC socket and the control board. The isolation board extends from the second half-shell to the first half-shell.
[0006] In some embodiments, the isolation heat dissipation structure further includes a flame-retardant heat-insulating member disposed on the side of the isolation board away from the AC socket.
[0007] In some embodiments, the isolation and heat dissipation structure further includes a heat sink, and the heat sink is clamped between the outer wall of the AC socket and the inner wall of the second half shell.
[0008] In some embodiments, the isolation and heat dissipation structure further includes an insulating layer, and the insulating layer is disposed between the heat sink and the AC socket.
[0009] In some embodiments, thermal conductive silicone is filled between the AC socket and the housing; and / or, thermal conductive silicone is filled between the heat sink and the AC socket.
[0010] In some embodiments, the heat sink is made of aluminum or copper; and / or, the insulating layer is an insulating plastic sheet.
[0011] In some embodiments, the periphery of the control board is wrapped with a heat dissipation component.
