Claim of US Patent No. 10,366,817

1. An electronic device assembly comprising:a heat dissipation member; and
a dielectric two-phase heat transfer device comprising:
an evaporator region coupled in thermal communication with a hot region of a heat producing component; and
a condenser region coupled in thermal communication with said heat dissipation member, said dielectric two-phase heat transfer device fabricated from a dielectric material,
wherein the heat producing component comprises a secondary winding portion of a transformer assembly, the secondary winding portion further comprising:
an upper conductive secondary turn; and
a lower conductive secondary turn,
wherein the dielectric two-phase heat transfer device extends about 180 degrees around the upper conductive secondary turn and the lower conductive secondary turn opposite a plurality of leads.
