Abstract

An electronic apparatus that includes: a housing having two surfaces extending in parallel, and a side surface connecting edges of the two surfaces; a circuit board placed in the housing and extends in parallel with the two surfaces; a plate member that extends to face a first surface of the circuit board; and a fan provided on a second surface of the circuit board, wherein the circuit board has a heat-generating electronic component mounted on the first surface and an opening through which air flows to the second surface side, and the plate member includes a concave groove formed in the first surface; a convex line formed on the second surface facing the circuit board on a portion corresponding to a back surface of the concave groove; and a guiding inclined surface formed on the back of the convex line to guide air to the opening.

Claims (12)

1. An electronic apparatus comprising:

a housing that includes two surfaces extending in parallel with each other, and a side surface connecting peripheral edges of the two surfaces to each other;

a circuit board that is placed in the housing and extends in parallel with the two surfaces;

a plate member that extends to face a first surface of the circuit board; and

a fan that is provided on a second surface of the circuit board, wherein

the circuit board has a heat-generating electronic component mounted on the first surface and an opening through which air on the first surface flows to the second surface, and

the plate member includes: a concave groove formed in a first surface facing a side opposed to the circuit board; a convex line formed on a second surface facing the circuit board on a portion corresponding to a back surface of the concave groove; and a guiding inclined surface formed on the back of the convex line to guide air on the first surface of the circuit board to the opening.

2. The electronic apparatus according to claim 1 , wherein the convex line extends while facing a plurality of heat-generating electronic components mounted on the first surface of the circuit board.

3. The electronic apparatus according to claim 1 , wherein the plate member further includes a heat receiving section which is formed in a convex shape to the heat-generating electronic component mounted on the circuit board, and comes in contact with the heat-generating electronic component through a heat-transfer agent for close contact.

4. The electronic apparatus according to claim 1 , further comprising a cable that extends through the concave groove.

5. The electronic apparatus according to claim 1 , further comprising a keyboard that is placed in contact with the first surface of the plate member.

6. The electronic apparatus according to claim 5 , further comprising a second housing that has a display panel and is openably and closably connected to the housing.
