Abstract

According to one embodiment, a housing of an electronic apparatus includes a first sidewall portion provided with an air vent, a ceiling wall portion extending from an upper end of the first sidewall portion toward the outside of the housing, and a pair of second sidewall portions which extend from respective side end portions of the first sidewall portion toward the outside of the housing and are opposed to each other.

Claims

1. An electronic apparatus comprising:

a housing comprising a sidewall portion and a bottom wall, the sidewall portion comprising an air vent, the bottom wall comprising a portion adjacent to the sidewall portion, and the bottom wall portion comprising a liquid discharge hole for discharging liquid that enters the housing through the air vent, a direct liquid path existing between the air vent and the liquid discharge hole,

a circuit board in the housing;

a heat-generating component on the circuit board, the heat-generating component being displaced from the direct liquid path;

a heat-transfer member having a first end thermally connected to the heat-generating component;

a heat-radiating member thermally connected to a second end of the heat-transfer member and horizontally displaced from the heat-generating component; and

a cooling fan for cooling the heat-radiating member,

wherein at least a portion of the liquid discharge hole is located directly below at least a portion of the heat-radiating member.

2. The electronic apparatus of claim 1, wherein a direct liquid path exists between the heat-radiating member and the liquid discharge hole.

3. The electronic apparatus of claim 1, wherein the heat-radiating member comprises a plurality of fins having clearances defined therebetween, the clearances opening downwardly.

4. The electronic apparatus of claim 1, wherein the ratio of the horizontal distance between an edge of the liquid discharge hole that is most distant from the sidewall portion and an outer edge of the sidewall portion is √

{square root over (3)} times as large as the vertical distance between an uppermost edge of the air vent and the bottom wall portion.
