Electronic apparatus
View Patent ↗According to one embodiment, an electronic apparatus includes a heating component, a housing, and a heat diffusing member. The housing accommodates the heating component and includes a wall. The wall includes a first region configured to receive heat from the component and a second region configured to have a lower temperature than a temperature of the first region. The heat diffusing member is attached to an inner surface of the wall and extends from the first region to the second region.
1. An electronic apparatus comprising:
a heating component;
a housing comprising a wall, the heating component in the housing, the wall comprising a first region that receives heat from the heating component and a second region that has a lower temperature than a temperature of the first region;
a heat diffusing member comprising a contour and a phase change material inside the contour, and attached to an inner surface of the wall and extending from the first region to the second region; and
a heat insulator between the heating component and the first region.
2. The electronic apparatus of claim 1 ,
wherein the heat diffusing member comprises a first portion attached to the first region and a second portion attached to the second region, and
the first portion faces the heating component.
3. The electronic apparatus of claim 2 , further comprising:
a circuit board comprising the heating component,
wherein the second portion is located away from an area facing the circuit board.
4. The electronic apparatus of claim 1 , further comprising:
a circuit board comprising a surface facing the wall,
wherein the heating component is on the surface of the circuit board.
5. The electronic apparatus of claim 1 ,
wherein a gap between the heating component and the heat diffusing member is smaller than a thickness of the wall.
6. The electronic apparatus of claim 1 ,
wherein a thickness of the heat diffusing member is less than a thickness of the wall.
7. The electronic apparatus of claim 1 ,
wherein the wall comprises a leg that is on an outer placement surface, and
the contour is formed of metal, and the heat diffusing member reinforces the wall.
8. The electronic apparatus of claim 1 , further comprising:
a fan in the housing,
wherein the second region is cooled by the fan.
9. The electronic apparatus of claim 8 ,
wherein the second region comprises a hole through which air flows toward the fan with the second region cooled.
10. The electronic apparatus of claim 1 , further comprising:
a heat diffuser having a greater width than a width of the heat diffusing member, the heat diffuser attached to the inner surface of the wall and thermally connecting the first region of the wall to the heat diffusing member.
11. The electronic apparatus of claim 1 , further comprising:
a heat diffuser having a greater width than a width of the heat diffusing member, the heat diffuser attached to the inner surface of the wall and thermally connecting the second region of the wall to the heat diffusing member.
12. The electronic apparatus of claim 1 ,
wherein the contour is formed of metal, and a phase of the phase change material changes between solid and liquid.
13. The electronic apparatus of claim 1 ,
wherein the heat diffusing member is a heat pipe.
