Patent ID: 8443874

Claim:
A heat dissipating structure comprising: a heat generating body; a heat transfer member thermally connected to said heat generating body and configured to transfer heat generated in said heat generating body; and a thermal storage unit thermally connected to said heat transfer member, wherein said thermal storage unit includes: a pack with stretching property; and a thermal storage medium which is filled in said pack and a volume of which changes with a change in temperature, said pack is arranged such that there is a gap between said pack and a first heat dissipating portion at normal temperature and said pack contacts said first heat dissipating portion when said thermal storage medium expands with a change in temperature, said heat transfer member is in contact with a second heat dissipating portion a location of which is different from a location of said first heat dissipating portion, the heat transfer member is configured to dissipate heat via said second heat dissipating portion, said heat transfer member and said thermal storage unit are arranged in a first enclosure of a portable device in which said first enclosure and second enclosure are connected via a hinge unit such that said first enclosure and said second enclosure are freely opened and closed, said first enclosure includes a side of said hinge unit and an opposite side of said hinge unit, said first heat dissipating portion is a portion of said opposite side of said hinge unit, and said second heat dissipating portion is arranged in said side of said hinge unit.
