[0028] The heat dissipation mechanism includes a heat dissipation component and a fixed connection component. The heat dissipation component is arranged on the lower surface of the main circuit board 101, and the fixed connection component is arranged at the four corners of the heat dissipation component.

[0029] In order to facilitate the heat dissipation of the composite PCB circuit board body 100 when it generates heat during long-term use through the heat dissipation component, in this embodiment, preferably, the heat dissipation component includes a heat sink 102 arranged on the lower surface of the main circuit board 101, and the surface of the heat sink 102 is provided with thermal grease 1022, and the surface of the heat sink 102 is contacted and connected with the lower surface of the main circuit board 101 through the thermal grease 1022.

[0030] In order to facilitate the fixed installation of the heat sink 102 when it is closed on the lower surface of the main circuit board 101 through the fixed connection component, in the present embodiment, preferably, the fixed connection component includes mounting feet 1021 arranged at the four corner positions of the lower surface of the heat sink 102, and the ends of the mounting feet 1021 are provided with fixing screws 1023, and the heat sink 102 is rotatably fixedly connected to the inside of the mounting hollow plate 1011 through the mounting feet 1021 and the fixing screws 1023, and the heat sink 102 is closed on the lower surface of the main circuit board 101, and the mounting feet 1021 are in contact with the surface of the mounting hollow plate 1011, and the fixing screws 1023 are rotated to fix the heat sink 102 for heat dissipation.

[0031] The working principle and use process of the utility model are as follows: before installing and using the composite PCB circuit board, the composite PCB circuit board is first fixedly installed. The installation hollow plate 1011 is placed at the installation position in the electronic device. The installation screws are inserted into the interior of the installation hole 1013 to rotate and fix the installation hollow plate 1011. The pull rod 1019 is pulled again to close the end of the clamping column 1016 in the interior of the groove 1010. The end of the main circuit board 101 is clamped in the interior of the installation groove 1012 by clamping the clamping plate 1015 in the interior of the clamping groove 1014. At this time, the composite PCB circuit board body 100 is clamped and installed. After clamping, the pull rod 1019 is released, and the spring 1018 is compressed. The deformation effect causes the clamping column 1016 to be elastically clamped in the clamping hole 1017 to clamp and fix the clamping plate 1015, so that the composite PCB circuit board body 100 is clamped and installed and then reinforced again, which is convenient for fixing and installing the composite PCB circuit board body 100 for use. When the internal components of the composite PCB circuit board body 100 are damaged after long-term use after being fixed and installed, the composite PCB circuit board body 100 can be quickly disassembled and repaired by the opposite operation, which is convenient for disassembly and repair, and is not easy to cause rotation and extrusion damage to the end of the composite PCB circuit board body 100, thereby improving the convenience and service life of the composite PCB circuit board body 100 during installation and use.

[0032] Then, after the composite PCB circuit board body 100 is fixedly installed by installing the hollow plate 1011, the heat sink 102 is closed on the lower surface of the main circuit board 101 again, and the upper surface of the heat sink 102 contacts the lower surface of the main circuit board 101 through the thermal conductive silicone grease 1022, and the bottom end of the mounting foot 1021 contacts the inner surface of the mounting hollow plate 1011 and is fixedly installed by rotating the fixing screws 1023, thereby fixing the heat sink 102 on the lower surface of the main circuit board 101. When the composite PCB circuit board body 100 generates heat internally during use, the heat sink 102 dissipates the heat on the lower surface of the main circuit board 101, accelerates the heat dissipation, thereby improving the heat dissipation effect of the composite PCB circuit board body 100 during installation and use, and extending the service life.
