[0029] See also Figures 1 to 5 In this embodiment, a gallium nitride fast charging module with a built-in dual-port protocol chip includes a shell 1, a main body 2, a bottom shell 4 and a decorative plate 5 for buckling on both sides of the shell 1.

[0030] Furthermore, the main body 2 uses gallium nitride as a conductor and has conventional components such as capacitors of a power adapter. At the same time, its circuit composition includes the following modules: circuit protection module, EMI module, main circuit module, and protocol circuit module.

[0031] Among them, the main body 2 has an interface 3 extended through a dual-port protocol chip, and the multi-channel output circuit is more stable and reliable through the design and application of circuit parallel connection. A wiring slot 14 corresponding to the interface 3 is opened through the decorative panel 5.

[0032] Preferably, a first fastener 6 is fixedly mounted on the bottom shell 4, and a second fastener 7 is fixedly mounted on the decorative panel 5. The first fastener 6 and the second fastener 7 are respectively fixed at the two end positions of the shell 1 to seal the shell 1 to form a complete power adapter.

[0033] In this embodiment, a heat dissipation structure is provided on the main body 2 for autonomously dissipating heat inside the shell 1, so that when the product is charging multiple high-power products at the same time, the temperature of the shell 1 and the device still meet the safety requirements, thereby ensuring the safety of the product.

[0034] The heat dissipation structure includes a guide frame 8 fixedly mounted on the main body 2 pcb board, and a heat dissipation box 10 fixedly mounted on the guide frame 8, wherein a micro fan 11 is fixedly mounted in the heat dissipation box 10, and the micro fan 11 and the capacitor of the pcb board are interconnected for power supply.

[0035] Specifically, the micro fan 11 uses a 3004-micro DC blower with a size of 30x30x4mm.

[0036] It should be noted that the guide frame 8 is U-shaped as a whole and is inverted on the main body 2. A converging pipe 9 is fixedly installed on the top of the guide frame 8. The converging pipes 9 are arranged in an array on the guide frame 8, and the converging pipes 9 are simultaneously connected to the inside of the guide frame 8 and the inside of the heat dissipation box 10, so that the heat dissipation box 10 is connected to the inside of the guide frame 8.

[0037] In a specific implementation, the micro fan 11 is controlled to suck the gas on the main body 2 inside the guide frame 8 into the interior of the heat dissipation box 10 through a plurality of converging pipes 9 .

[0038] Furthermore, exhaust holes 12 for exhausting gas are opened through the outer wall of the heat dissipation box 10. The exhaust holes 12 are distributed on the left and right sides of the heat dissipation box 10, and are used to gather the gas passing through the main body 2 and then discharge it.

[0039] It should be noted that air vents 13 for discharging gas and dissipating heat are provided on the front and back sides of the shell 1. By staggering the air vents 13 and the exhaust holes 12, the flow range of gas in the shell 1 is expanded, so as to evenly distribute the heat source and dissipate heat through indirect heat conduction, making the product design more compact.

[0040] Preferably, a guide plate 16 is fixedly installed on the inner wall of the guide frame 8. The guide plate 16 is arranged perpendicular to the converging tube 9. The guide plate 16 guides the gas passing through the inner side of the guide frame 8, so that the gas circulates and fills the inside of the guide frame 8, thereby improving the uniformity of the gas distribution outside the main body 2.

[0041] In order to allow the circulating gas to act as a medium to carry heat out of the shell 1 through indirect contact heat conduction, the decorative panel 5 in this embodiment is provided with an array of heat dissipation holes 15. Through the heat dissipation holes 15, the circulated gas can be easily sent out of the shell 1, thereby realizing self-dissipation of the heat generated in the shell 1.

[0042] The working principle of the above embodiment is:

[0043] By controlling the micro fan 11, the micro fan 11 draws the gas inside the guide frame 8 into the interior of the heat dissipation box 10 through several converging pipes 9 connected to the external heat dissipation box 10. At this time, the heat generated by the components on the main body 2 can be carried away by indirect contact through the gas as a medium. At the same time, due to the influence of the guide frame 8 and the guide plate 16, the gas is sucked into the shell 1 through the air vents 13 on the side of the shell 1, and after circulating through the entire main body 2, it is discharged through the exhaust holes 12 opened on the heat dissipation box 10, and the air is guided out through the heat dissipation holes 15 on the decorative panel 5, thereby realizing a circulated and evenly distributed heat source and autonomous heat dissipation, while avoiding the harm of local heat concentration.

[0044] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0045] This gallium nitride fast charging module with a built-in dual-port protocol chip divides the interior of the shell around the main area by setting a guide frame and a heat dissipation box inside the power adapter. When the micro fan in the heat dissipation box introduces gas, it can circulate inside the shell with air as the medium and indirectly contact the heat source, thereby achieving independent heat dissipation and evenly distributed heat source. On the one hand, when the product is charging multiple high-power products at the same time, its shell temperature and device temperature still meet safety requirements, thereby ensuring product safety. On the other hand, it can also make the heat evenly distributed to avoid overheating in local areas.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
