DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See Figures 1 - 5 As shown, in the embodiment of the present utility model, an air-cooled charger is proposed, which includes an upper shell 1 and a lower shell 2. A sealing groove 3 is arranged along the edge on the lower shell 2 and a sealing strip is arranged in the sealing groove 3. The upper shell 1 is fastened on the lower shell 2 and presses the sealing strip. The sealing strip is limited by the sealing groove 3, and the upper shell 1 and the lower shell 2 are fastened by screws arranged along the edge to realize the sealing of the connection position and protect the interior. At the same time, a plurality of independently arranged and separated chambers 4 are arranged in the lower shell 2. A charging circuit integration module 5 is installed in the lower shell 2, and the heating devices in the charging circuit integration module 5 are respectively placed in the independent chambers 4. Among them, the charging circuit integration module 5 is a prior art and the whole module can be directly applied to realize current conversion. The charging circuit integration module 5 generates heat during the charging process. The heating devices therein are separately placed in the independent chambers 4 to avoid the internal heat from flowing chaotically. At the same time, heat-conducting glue is filled in the independent chambers 4, and the heat-conducting effect of the heat-conducting glue is used to improve the transfer of internal heat to the lower shell 2. After the internal heat is generated, it is conducted to the outside through the lower shell 2. Specifically, a heat dissipation groove 6 is also arranged on the outer side of the lower shell 2, and a heat dissipation fan 7 is installed in the heat dissipation groove 6. The heat dissipation fan 7 accelerates the air flow at the position of the heat dissipation groove 6 to improve the heat exchange efficiency and accelerate the heat dissipation of the internal heat. At the same time, a fan cover 8 for covering the heat dissipation fan 7 is installed on the lower shell 2, and the fan cover 8 can realize air diversion and improve the air flow at the position of the heat dissipation groove 6.

[0027] In order to further improve the heat conduction and heat dissipation effects, a number of heat dissipation fins 10 arranged at intervals are arranged on the outer side wall of the lower shell 2, and the heat dissipation fins 10 extend to the heat dissipation groove 6. The fan cover 8 covers the heat dissipation fins 10, and the heat dissipation fins 10 are used to increase the heat exchange area and improve the heat dissipation efficiency.

[0028] In order to ensure the heat conduction performance of the lower shell 2, the lower shell 2 is of an integral aluminum alloy die-casting structure.

[0029] The side of the fan cover 8 is bent with a wind guiding part extending downward obliquely to make the external air flow smooth and accelerate the air flow efficiency.

[0030] When the upper shell 1 and the lower shell 2 are hermetically connected, they may come into contact with the internal charging circuit integration module 5. In order to achieve insulation, an insulating pad 11 is pasted on the inner side surface of the upper shell 1.

[0031] Meanwhile, when the entire charger is installed, wall-mounted installation or vehicle-mounted installation is achieved through the upper shell 1. Specifically, the upper shell 1 is a flat structure, and installation ears 12 extending outward are provided at both ends of the upper shell 1 at intervals. Mounting holes 13 are provided on the installation ears 12, and the reserved mounting holes 13 facilitate the installation of the entire charger.

[0032] Since good sealing is achieved between the upper shell 1 and the lower shell 2, interfaces are required for internal and external connections. A plurality of connectors 9 for connecting the charging circuit integration module 5 are also provided on the lower shell 2. The types of the connectors 9 include input connectors 9, output connectors 9, communication connectors 9, and USB connectors 9.
