Novel heat radiation structure of PCB board

The utility model relates to a PCB board technical field especially is a novel heat radiation structure of PCB board, including the PCB board, one side of PCB board is provided with rivet hole, and rivet hole's inside is provided with the heat dissipation rivet. The heat that the source gived off of generating heat is dispelled the heat the rivet and adsorbs and conduct away, utilizes the heat dissipation rivet to go out heat conduction and radiation, has accelerateed radiating process on the PCB board, but dispels the heat the automated production of rivet simultaneously and install, comparesin traditional fin form, has realized high efficiency's production, has improved the production efficiency of product, steam enters into the inside second cavity intracavity of rivet rod through thebottom of riveting pipe, and external air conditioning enters into the inside first cavity intracavity of rivet head through the rivet head top, and steam cavity and second cavity intracavity in firsttransmits on the one hand,
