▎ 摘　　要

NOVELTY - The electronic device has a first heat generating portion and second heat generating portion which are provided in a housing. A cooling module (22) thermally absorbs the heat generated by the heat-generating portions. A vapor chamber (34) is formed in a portion pinched between a first metal plate (36) and a second metal plate (41), and provided to enclose the working fluid with sealed space. A thermally-conductive plate (37) containing graphene is supported by a metal frame (35). The vapor chamber and the thermally conductive plate are arranged so that thermal absorption of the heat produced by the first and second metal plates is possible. A ventilation fan is provided to ventilate a cooling fin (38) that is thermally connected with the metal plate. USE - Electronic device e.g. notebook type personal computer of clamshell type. Can also be used in mobile telephone, smartphone or portable game machine. ADVANTAGE - The number of components can be reduced, and the weight reduction of the electronic device can be achieved. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the cooling module and side surface of the motherboard in electronic device.
