Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] like Figures 1 to 5 As shown, an electrical module 10 with a heat dissipation structure according to this application includes: an electrical module 11, a fan 12, and a heat conductor 13. During installation, the heat conductor 13 is fixed to the inner side of the housing of the electrical module 11, and then the heat conductor 13 is attached to the electrical component 15 inside the electrical module 11, thereby enabling direct heat conduction and dissipation of the electrical component 15. The heat conductor 13 has multiple heat dissipation fins 131 arranged side-by-side and spaced apart to form multiple heat dissipation channels 132. The air outlet 121 of the fan 12 inside the electrical module 11 is opposite to the multiple heat dissipation channels 132. The housing of the electrical module 11 has multiple airflow holes 111 for internal airflow. The multiple heat dissipation channels 132 and the multiple airflow holes are opposite to each other. In this way, when the entire telecommunications module is started, the heat conductor 13 can directly conduct heat to the electrical components 15. Then, the fan 12 blows air through the air outlet 121 onto the heat sink 131. The air then forms convection through the fan 12, the heat dissipation channel 132 and the air guide hole 111, thereby quickly dissipating the heat of the heat sink 131 to the outside of the electrical module 11.

[0024] Based on the above structure, the shape of the air outlet 121 of the fan 12 is designed to be the same as the overall shape of the multiple heat dissipation fins 131, and the air outlet 121 of the fan 12 is fitted to the side of the overall structure formed by the multiple heat dissipation fins 131. This not only increases the airflow and velocity per unit area of ​​the heat dissipation fins 131, thereby effectively improving heat dissipation performance, but also reduces the overall size of the fan 12 and heat conductor 13 installation structure. Furthermore, the extending direction of the multiple heat dissipation channels 132 is parallel to the extending direction of the multiple air guide holes 111, and the multiple heat dissipation fins 131 are respectively aligned with the center face of the corresponding air guide holes 111, thereby further improving the heat dissipation effect of the fan 12 blowing air in conjunction with the heat dissipation channels 132 and the air guide holes 111.

[0025] The electric module 10 with the heat dissipation structure has the heat dissipation structure with high heat dissipation performance by arranging the fan 12 and the heat conductor 13 inside and cooperating with the flow guide hole 111, so that the high-temperature gas inside the electric module is blown out to the outside of the electric module through the air outlet 121 of the fan 12, the heat dissipation channel 132 and the flow guide hole 111, heat exchange is performed through air convection, high-efficiency heat dissipation is realized, the overall heat dissipation structure is compact in size, small in structure, and small in occupied installation space.

[0026] As a specific embodiment, the fan 12 is mounted on the heat conductor 13 to form an installation whole, which is compact in structure and convenient to install. The side of the heat conductor 13 away from the electric element 15 of the electric module 11 is provided with a mounting portion 133 for supporting the fan 12, and a plurality of studs 135 are arranged above the mounting portion 133. The fan 12 is fixed to the mounting portion 133 by screwing the studs 135 through the fan 12 and rotating into the studs 135, and the mounting structure is simple and convenient to disassemble and assemble.

[0027] Further, the bottom side of the fan 12 is arranged in abutment with the mounting portion 133, so that the internal motor of the fan 12 can be cooled to ensure the stability of the fan 12, and the occupied space of the overall heat dissipation structure is reduced, and the structure is more compact.

[0028] As a specific embodiment, the side of the heat conductor 13 for facing the electric element 15 of the electric module 11 is provided with a heat conduction surface 134, which is arranged in abutment with the electric element 15 of the electric module 11 to improve the heat conduction efficiency of the heat conductor 13 to the electric element 15, and also reduce the influence of the overall structure of the heat conductor 13 and the fan 12 on the internal installation space. In addition, heat-conducting silica gel is arranged on the heat conduction surface 134 to improve the heat conduction.

[0029] As a specific embodiment, a plurality of heat dissipation fins 112 are arranged on the outer side of the shell of the electric module 11 at the hole of the flow guide hole 111 to dissipate heat, so that the internal heat dissipation is performed through air convection of the flow guide hole 111, and the internal heat dissipation is also performed through the shell of the electric module, and the overall heat dissipation performance is higher.

[0030] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the above examples do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
