Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with power supply over-temperature protection. Background Art

[0002] Power adapters are an integral part of modern electronic devices, converting alternating current (AC) into direct current (DC) suitable for specific devices. After extensive research, publication number CN218041225U was found, which discloses a power adapter comprising a power adapter body and a support stand. The power adapter body is equipped with a heat sink, a heat conducting column, and a heat sink extending into the inner cavity of the power adapter body. Heat dissipation holes are also provided on the surface of the heat conducting column, improving the heat dissipation efficiency of the device.

[0003] When the above device is in use, heat dissipation holes are opened on the heat-conducting column. Although this can improve the heat dissipation effect to a certain extent, the provision of the heat dissipation holes increases the risk of water and dust ingress. At the same time, when the above device is in use, air circulation can only be carried out through the limited space provided by the heat dissipation holes, and the internal heat of the device is dissipated by means of the circulating air. When the heat dissipation adapter works for a long time, its internal temperature is difficult to cool down quickly, which directly affects the performance and life of the adapter, and is also related to the safety of use. Therefore, a power adapter with power supply overtemperature protection is needed to solve the above problems. Utility Model Content

[0012] Preferably, a mounting slot is defined at the front end of the upper end of the panel, into which a display screen is embedded. The display screen is made of an LCD material and is electrically connected to the mainboard. This design not only provides an intuitive user interface, but also allows for real-time monitoring of the power adapter's operating status, including temperature information and any abnormality warnings, through the display screen, greatly enhancing the user experience and device monitoring capabilities.

[0013] Preferably, the top and bottom of the thermal column are coated with thermally conductive silicone, and the connection between the column and the insertion slot is filled with sealant.

This design allows the heat generated by the processor to be directly transferred to the thermal column, and the heat is conducted to the outside through the thermal column to achieve effective heat dissipation. The contact between the thermal column and the processor is not fixed. This design can adapt to thermal expansion and mechanical vibration to a certain extent, and reduce the thermal stress and mechanical stress caused by fixed connection. Screw holes are provided on the outside of the insertion slot on the panel. This design allows the heat dissipation component on the panel to be fastened by screws and enhances the sealing, thereby preventing moisture and dust from entering the adapter through the gap.

The design of the heat sink 61 takes into account the convenience of installation and structural stability. The opening design at the four corners of the bottom of the heat sink 61 allows the mounting screws to be movably inserted. This design simplifies the installation process while providing a secure fixation. At the same time, the mounting screws pass through the heat sink 61 and are threaded into the screw hole 52, ensuring a tight connection between the heat sink assembly 6 and the power adapter body 2, enhancing the stability of the overall structure.

[0030] Furthermore, the top and bottom of the thermal conductive column 71 are coated with thermally conductive silicone, and the connection between the thermal conductive column 71 and the insertion slot 53 is filled with sealant.
