VAPOR CHAMBER STRUCTURE

摘要

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.

1. A vapor chamber structure, comprising:
an extruded aluminum case (10) having a bottom plate (11) and a plurality of first separating units (12) extending upward from the bottom plate (11), wherein each of the first separating units (12) comprises a plurality of first fins (121), wherein a first groove (122) is disposed between any two adjacent first fins (121); an extruded aluminum cover (20) combined with the extruded aluminum case (10) correspondingly, wherein the extruded aluminum cover (20) has a top plate (21) and a plurality of second separating units (22) extending downward from the top plate (21), wherein each of the second separating units (22) comprises a plurality of second fins (221), wherein a second groove (222) is disposed between any two adjacent second fins (221), wherein the each of the second separating units (22) is disposed between any two adjacent first separating units (12), wherein the first grooves (122) of the first separating units (12) are individually interlaced with the adjacent second grooves (222) of the second separating units (22); and a working fluid (30) filled in an interior formed by the extruded aluminum case (10) and the extruded aluminum cover (20).
