Abstract

An electronic device includes: a housing that has a first principal surface, a second principal surface on an opposite side of the first principal surface, and a side surface connecting the first principal surface and the second principal surface; a fan disposed inside the housing; an air passage disposed inside the housing and through which air sent from the fan passes; and a fin disposed in the air passage. The air passage extends from the fan toward the side surface. The housing has a recess recessed from the second principal surface toward the first principal surface and extending toward the side surface, at a position overlapping with the air passage in a plan view. The recess has a recessed surface facing the first principal surface, and a recess side surface positioned nearer to the fin than the side surface is in an extending direction of the air passage.

First claim

The invention claimed is:

1. An electronic device comprising:
a housing that has a first principal surface, a second principal surface on an opposite side of the first principal surface, and a side surface connecting the first principal surface and the second principal surface;
a fan that is disposed inside the housing;
an air passage that is disposed inside the housing and through which air sent from the fan passes; and
a fin that is disposed in the air passage,
wherein
the air passage extends from the fan toward the side surface,
the housing has a recess recessed from the second principal surface toward the first principal surface and extending toward the side surface, at a position overlapping with the air passage in a plan view,
the recess has a recessed surface facing the first principal surface, and a recess side surface that is positioned nearer to the fin than the side surface is in an extending direction of the air passage and that connects the second principal surface and the recessed surface,
the side surface has a first exhaust port through which a part of air sent by the fan is discharged, and
the recess side surface has a second exhaust port through which another part of the air sent from the fan is discharged.

2. The electronic device according to claim 1 , wherein the first exhaust port has a size larger than a size of the second exhaust port in a thickness direction of the housing.

3. The electronic device according to claim 1 , wherein the second exhaust port has an opening stretching across the second principal surface and the recess side surface.

4. The electronic device according to claim 1 , wherein the recessed surface is flat.

5. The electronic device according to claim 1 , further comprising an antenna disposed on the recessed surface inside the housing.

6. The electronic device according to claim 5 , wherein the recessed surface is inclined with respect to the first principal surface toward the side surface.

7. The electronic device according to claim 1 , wherein the fin is disposed adjacently to the second exhaust port.

8. The electronic device according to claim 1 , wherein
the first exhaust port has a plurality of first through holes, and
the second exhaust port has a plurality of second through holes.

9. The electronic device according to claim 8 , wherein a size of each of the plurality of first through holes is larger than a size of each of the plurality of second through holes.

10. The electronic device according to claim 1 , further comprising a display unit disposed on the first principal surface.
