[0030] An internal radiator 4, the first end of the internal radiator 4 is fixed to the external radiator 3, and the second end of the internal radiator 4 is fixed to the first heat generating device 5 of the power supply part.
[0031] Specifically, the present utility model provides an air-cooled, waterproof and dustproof charger. The housing and the cover plate form an accommodation space, which is airtight. A power supply part and a heat dissipation part are arranged inside the accommodation space, so that the charger has both heat dissipation and waterproof and dustproof effects, can resist external interference, and reduce the product failure rate.
[0032] In a preferred embodiment, the power supply part further includes a second heat generating device 6, the second heat generating device 6 is fixed to the external radiator 3, the first heat generating device 5 is a heat generating magnetic core component, and the second heat generating device 6 is a heat generating MOS tube;
[0033] The internal radiator 4 includes a plurality of air duct partitions 41, and the distance between adjacent air duct partitions 41 is equal;
[0034] One end of the external radiator 3 is provided with a cooling fan 7.
[0035] Specifically, devices such as heat generating MOS tubes that are convenient to be installed on the external radiator 3 form an isolation air duct in contact with the outside air through the external radiator 3, the housing 1 and the air duct partitions 41. The cooling fan 7 is installed at the air duct air inlet, and the outside air flows through the air outlet through the air inlet, efficiently taking away the heat on the external radiator 3, and at the same time isolating water vapor and dust, achieving a waterproof and dustproof effect.
[0036] More specifically, the heat generating magnetic core component transfers the heat on the internal radiator 4 to the external radiator 3 by conduction through the connection between the internal radiator 4 and the external radiator 3, and then the cooling fan 7 takes away the heat on the external radiator 3.
[0037] In a preferred embodiment, a thermal conductive adhesive is provided between the internal radiator 4 and the first heat generating device 5.
[0038] Specifically, the thermal conductive adhesive can effectively improve the heat conduction efficiency. The heat generated by the first heat generating device 5 is more effectively transferred to the radiator through the thermal conductive adhesive, which helps to reduce the working temperature of the first heat generating device 5 and improve its stability and service life.
[0039] More specifically, the thermal conductive adhesive can fill and level the tiny gap between the radiator and the first heat generating device 5, thereby reducing the thermal resistance.
[0040] In a preferred embodiment, the housing 1 is provided with an air outlet hole 8 corresponding to the position of the cooling fan 7.
[0041] Specifically, the air outlet hole 8 can directly discharge the air sucked by the cooling fan 7, effectively promoting air circulation, helping to quickly take away the heat from the inside of the device, reducing the internal temperature, and thus improving the heat dissipation efficiency.
[0042] More specifically, through the air outlet hole 8, the hot air inside the device can be quickly discharged, preventing it from accumulating inside the device and causing a temperature rise. It prolongs the service life of the internal components and reduces device damage or performance degradation caused by excessive temperature. The air outlet hole 8 ensures the effective operation of the heat dissipation system, helping to maintain the stability and reliability of the device. By optimizing heat dissipation, the air outlet hole 8 can help the device maintain stable performance during high-load or long-term use.
[0043] In a preferred embodiment, the housing 1 and the cover plate 2 are fixed by screws.
[0044] Specifically, screw fixation can ensure that the housing 1 and the cover plate 2 are tightly connected, effectively preventing loosening or displacement due to vibration or external force. By tightly fixing, the screws can reduce the gap between the housing 1 and the cover plate 2, thus preventing external dust, moisture or other harmful substances from entering the inside of the device, which has a positive impact on waterproofing, dustproofing, improving the reliability and maintenance cycle of the device.
[0045] More specifically, the fixing screws are usually designed with a structure that can be screwed and disassembled, so that the device can be easily disassembled and reassembled when maintenance or repair is needed, reducing the time and labor costs during the maintenance process. It increases the strength and stiffness of the overall structure, improves the vibration resistance and shock resistance of the device, and thus reduces structural damage caused by changes in the external environment or accidental impacts during operation.
[0046] In a preferred embodiment, the external radiator 3 is fixed to one side of the housing 1 by screws.
[0047] Specifically, screw fixation can ensure that the radiator is firmly mounted on the housing 1 and will not loosen or displace due to vibration or external force. The external radiator 3 is fixed to one side of the housing 1, enabling it to effectively conduct the heat from the inside of the device. Good fixation ensures good contact between the radiator and the internal heat sources (such as electronic components or processors), thereby improving the heat transfer efficiency.
[0048] More specifically, by fixing the external radiator 3, the accumulation of heat at the contact interface can be effectively avoided, ensuring that the heat can be quickly transferred to the surface of the radiator and dissipated, which helps to maintain the temperature inside the device within a safe range and reduces the risk of overheating and failure of the device caused by poor heat dissipation.
[0049] In a preferred embodiment, the first end of the internal radiator 4 is fixed to the external radiator 3 by screws.
[0050] Specifically, fixing the internal radiator 4 on the external radiator 3 can ensure good contact and heat conduction between the two, thereby optimizing the overall heat dissipation efficiency. The heat can be more effectively transferred from the internal radiator 4 to the external radiator 3, further improving the heat dissipation efficiency.
[0051] More specifically, it can also prevent the separation or loosening between the two due to vibration or movement during the operation of the device. The space can be effectively utilized and the design can be simplified. Especially in devices or machines with limited space, this integrated design can save internal space and make the device layout more compact and effective.
[0052] In a preferred embodiment, the second heating device 6 is fixed to the side of the external radiator 3 facing the power supply unit by screws.
[0053] Specifically, fixing the second heating device 6 on the external radiator 3 can optimize the heat dissipation path, ensure that the heat can be quickly and effectively transferred to the surface of the external radiator 3, significantly improve the overall heat dissipation efficiency, and prevent the heat from accumulating inside the device.

[0055] Specifically, the external radiator 3 of the present utility model is fastened to the housing 1 by screws. The air duct partition 41 is fixed to the external radiator 3 by screws. Through the installation relationship of the external radiator 3, the air duct partition 41, and the housing 1, a heat dissipation air duct in contact with the external environment and isolated from the inside of the housing 1 is formed.
[0056] More specifically, the internal radiator 4 is fixed to the heat-generating magnetic core components of the power supply unit by thermal conductive adhesive, and at the same time, the internal radiator 4 is connected to the air duct partition 41 by screws. Through this installation relationship, the heat of the components with large internal heat generation is brought to the external radiator 3 in contact with the outside through conduction.
[0057] More specifically, the heat-generating MOS transistor on the power supply unit is fixed to the external radiator 3 by screws. The cooling fan 7 is fixed to the external radiator 3 by screws. The cooling fan 7 is placed inside the air duct formed by the external radiator 3, the air duct partition 41, and the housing 1 to maximize the use of the air sucked in from the air inlet to blow to the air outlet. The cover plate 2 is fixed to the housing 1 by screws to form a waterproof and dustproof internal space. This solves the problem that the existing air-cooled chargers are greatly affected by the external environment and cannot be waterproof and dustproof.
[0058] In summary, the present application provides an air-cooled waterproof and dustproof charger. The housing 1 and the cover plate 2 are installed together by screws to form a waterproof and dustproof enclosed space. At the same time, through the connection of the internal radiator 4 and the external radiator 3, the heat on the internal radiator 4 is transferred to the external radiator 3 by conduction, and then the heat on the external radiator 3 is taken away by the cooling fan 7, combining waterproofing, dustproofing, and heat dissipation.
