Heat-radiating structure with low height

摘要

A heat-radiating structure with low height, including a first heat-radiating plate and a second heat-radiating plate spaced above the first heat-radiating plate. The first heat-radiating plate is formed with multiple first perforations arranged at intervals and multiple first dents arranged at intervals and extending downward. The second heat-radiating plate is formed with multiple second perforations arranged at intervals and multiple second dents extending downward and fitted with the first perforations. A heat-generating body such as a CPU is adjacent to outer sides of the bottoms of the first and second dents. The heat-radiating structure has a height much smaller than that of a conventional vertical heat-radiating plate and a heat conducting area much larger than that of the vertical heat-radiating plate. Accordingly, the heat-radiating structure can achieve better heat-radiating effect and is applicable to those products having small internal space and necessitating heat-radiation, such as a portable computer.
