Abstract

An external cellular heat sink structure includes a base and a heat dissipating body integrally formed on the base. The heat dissipating body includes a plurality of hollow cellular units, wherein the neighboring cellular units are connected together, and each cellular unit has at least two openings for communicating the connected cellular units with each other. Thus, the cellular unit can provide the larger dissipation area, and each opening can let the gas pass and disperse the gas so that the time and possibility for the gas to contact the heat dissipating surface are lengthened and increased, respectively, and the heat dissipation efficiency is increased.

Claims

exact text as granted — not AI-modified
1 . An external cellular heat sink structure, comprising:
 a base; and   a heat dissipating body integrally formed on the base,   wherein the heat dissipating body comprises a plurality of hollow cellular units, the neighboring cellular units are connected together, and each of the cellular units has at least two openings communicating with the connected cellular units.   
     
     
         2 . The heat sink structure according to  claim 1 , wherein the cellular unit has a hexagonal column structure. 
     
     
         3 . The heat sink structure according to  claim 1 , wherein the two openings of the cellular unit extend in different directions. 
     
     
         4 . The heat sink structure according to  claim 1 , wherein the two openings of the cellular unit are disposed opposite each other. 
     
     
         5 . The heat sink structure according to  claim 1 , wherein each of two sides of one of the openings of the cellular unit has a cell wall, and a wall edge of one of the cell walls is an arced wall edge. 
     
     
         6 . The heat sink structure according to  claim 1 , wherein a top edge of the heat dissipating body is formed with an arced structure having two sides and a middle portion higher than the two sides. 
     
     
         7 . The heat sink structure according to  claim 1 , wherein a top edge of the heat dissipating body is formed with a continuous arced wavy structure. 
     
     
         8 . The heat sink structure according to  claim 1 , wherein the base is an upper lamp shell of a LED road lamp.
