Beschreibung
Zusammenfassung:	The utility model provides a multi-cavity heat dissipation flow guide structure which comprises a positioning body, a heat dissipation device and a cover body, wherein a heating article or a heat pipe is assembled in the positioning body, the heat dissipation device is assemble on the outer periphery of the positioning body, heat produced by the heating article is transmitted to the positioning body and then transmitted to the heat dissipation device, and the cover body is arranged below the positioning body and the heat dissipation device. The multi-cavity heat dissipation flow guide structure is characterized in that the heat dissipation device is provided with plural cavities, the cavities penetrate through the heat dissipation device, the cover body is provided with a spiral inner surface which serves as a flow guide thread surface, cold air can be guided and concentrated below the cover body and into each cavity of the heat dissipation device as a spiral by the flow guide thread surface, the cold air pas
