Abstract

An electronic device includes a housing body, a dividing member that divides the housing body into a first compartment and a second compartment, a sealing member that divides the first compartment into a liquid-stopper region and an exterior communication region, one or more heat emitting components disposed in the liquid-stopper region, a fan disposed in the exterior communication region, and a ventilation pathway through which an airflow passes through the dividing member to the second compartment due to driving the fan.

Claims (28)

1. An electronic device comprising:

a housing body that includes a first plate member, and a second plate member disposed facing the first plate member;

a dividing member that is disposed between the first plate member and the second plate member and that is parallel to the first plate member, a surrounding of the dividing member touching the housing body and dividing a space between the first plate member and the second plate member into a first compartment and a second compartment;

a sealing member that forms a closed curve, that is disposed in the first compartment, that makes close contact with the first plate member and the dividing member, and that divides the first compartment into a liquid-stopper region and an exterior communication region;

a substrate that is a separate body from the dividing member, wherein in plan view, the substrate is located inside of the outline of the dividing member and is disposed in the liquid-stopper region, and one or more heat emitting components are mounted on the substrate;

a fan disposed in the exterior communication region; and

ventilation holes formed in a portion of the dividing member, through which an airflow passes to the second compartment due to driving the fan.

2. The electronic device of claim 1 , wherein at least one of the heat emitting components is disposed in contact with the dividing member.

3. The electronic device of claim 1 , wherein a contact portion of the dividing member, which is in contact with the heat emitting component, is made of metal.

4. The electronic device of claim 3 , wherein the contact portion is a metal plate that is removable from the dividing member.

5. The electronic device of claim 4 , wherein, when the metal plate is in a state of being attached to the dividing member, the metal plate covers an opening in the dividing member.

6. The electronic device of claim 1 , wherein a plurality of air intake holes are provided for air to flow to the second compartment.

7. The electronic device of claim 6 , wherein the air intake holes are provided at a plurality of side faces of the housing body.

8. The electronic device of claim 1 , further comprising:

a cable that electrically connects the substrate to the fan.

9. The electronic device of claim 8 , further comprising a first liquid-stopper member that acts as a liquid-stopper between the sealing member and the cable.

10. The electronic device of claim 9 , wherein:

a plurality of the cables are provided; and

the first liquid-stopper member includes close-contact holes that make close contact with, and retain; each of the cables with the plurality of cables in a separated state.

11. The electronic device of claim 10 , wherein the close contact holes each retain one out of the plurality of cables.

12. The electronic device of claim 10 , wherein:

the first liquid-stopper member is formed with slits in the close contact holes to house the cables; and

the sealing member partially enters the slits.

13. The electronic device of claim 9 , wherein:

the first liquid-stopper member includes slits through which each of the plurality of the cables is passed, and an inner diameter of each of the close-contact holes is smaller than an outer diameter of each of the cables.

14. The electronic device of claim 1 , further comprising a heat pipe that places at least one of the heat emitting components in communication with a blower of the fan airstream in the exterior communication region.

15. The electronic device of claim 14 , further comprising a second liquid-stopper member that acts as a liquid-stopper between the housing body and the heat pipe.

16. The electronic device of claim 15 , wherein the sealing member is in close contact with the heat pipe at an opposite side from a second liquid-stopper member side.
