Abstract

A portable electronic apparatus includes a first unit, a second unit, and a hinge unit. The first unit includes a first housing, a heat generating component inside the first housing, a first heat diffusing member disposed inside the first housing and diffusing heat from the heat generating component, and a heat dissipating part dissipating heat diffused by the first heat diffusing member to the outside of the first housing. The second unit includes a second housing, a second heat diffusing member disposed inside the second housing and diffusing heat inside the second housing, and a heat receiving part conducting heat from the heat dissipating part to the second heat diffusing member upon the heat receiving part being in contact with the heat dissipating part.

Claims (13)

1. A portable electronic apparatus comprising:

a first unit including

a first housing,

a heat generating component disposed inside the first housing,

a first heat diffusing member disposed inside the first housing and configured to diffuse heat inside the first housing, the heat being generated by the heat generating component, and

a heat dissipating part configured to dissipate heat diffused by the first heat diffusing member to the outside of the first housing,

an elastic member disposed inside the first housing between a substrate and the first heat diffusing member and configured to press the heat dissipating part; and

a second unit configured to slide on the first unit, the second unit including

a second housing,

a second heat diffusing member disposed inside the second housing and configured to diffuse heat inside the second housing, and

a plurality of heat receiving parts disposed to be apart from each other, disposed to be in contact with the heat dissipating part upon a slide width of the second unit being a predetermined width and configured to conduct heat from the heat dissipating part to the second heat diffusing member upon each of the heat receiving parts being in contact with the heat dissipating part.

2. The portable electronic apparatus according to claim 1 , wherein one of the plurality of heat receiving parts is arranged to be in contact with the heat dissipating part when the slide width of the second unit is zero width and a maximum width.

3. The portable electronic apparatus according to claim 2 , wherein one of the plurality of heat receiving parts is arranged to be in contact with the heat dissipating part when the slide width of the second unit is some width other than zero width and a maximum width.
