Abstract: A thermal management system (10) provides a heat dissipating component using a high thermal conductivity insert (22). The heat dissipating component may be a spreader (12) or heat sink, and includes a planar graphite member (16) having high thermal conductivity along the plane of the member (X, Y) and having a relatively low thermal conductivity through the thickness of the member (Z). A cavity (20) is formed through the thickness of the member and the high conductivity insert (22) is received in the cavity (20). The insert (22) may be an isotropic high thermal conductivity material such as copper or an anisotropic material such as graphite oriented to have high conductivity in the direction of the thickness of the planar element (Z).
