Abstract
A vapor chamber structure includes an extruded aluminum case having a bottom plate and plural first separating units, an extruded aluminum cover combined with the extruded aluminum case correspondingly and having a top plate and plural second separating units, and a working fluid filled in an interior formed by the extruded aluminum case and the extruded aluminum cover. Each first separating unit includes plural first fins. A first groove is disposed between adjacent first fins. Each second separating unit includes plural second fins. A second groove is disposed between adjacent second fins. Each second separating unit is disposed between adjacent first separating units. The first grooves are individually interlaced with the adjacent second grooves. Thus, the heat exchange between the vaporized working fluid and the gas in adjacent grooves can be performed, which improves the efficiency of heat transfer.
