Disclosed is a method for integrating at least two heat transfer members to provide an integrated composite member, the method comprising: a) disposing the at least two heat transfer members in a mold cavity, such that said heat transfer members each have at least one exposed surface forming a surface of a resin injection cavity; and b) injecting a thermally conductive resin into the resin injection cavity to contact the exposed surfaces of the at least two heat transfer members, to form the integrated composite member; wherein the thermally conductive resin has a thermal conductivity of at least 0.7 W/mK or higher.
