Abstract

An information processing device includes a board, a receiver that includes a top wall facing the board, the receiver to allow a coupling device to be inserted into a space between the board and the top wall, a movable part provided in the top wall, the movable part to be movable in a direction facing the board, the movable part having a contact portion to be in contact with a top surface of the coupling device, an elastic part that has elasticity provided at the movable part, the elastic part urging the movable part toward the board, a heat sink thermally coupled to the movable part through the elastic part, a housing positioned over a side opposite the board relative to the heat sink, the housing having a facing wall facing the heat sink, and a fan to supply wind to the heat sink along the facing wall.

First claim

What is claimed is:

1. An information processing device comprising:
a board;
a receiver that includes a top wall facing the board, the receiver configured to allow a coupling device to be inserted into a space between the board and the top wall;
a movable part provided in the top wall, the movable part configured to be movable in a direction facing the board, the movable part having a contact portion configured to be in contact with a top surface of the coupling device;
an elastic part that has elasticity provided at the movable part, the elastic part urging the movable part toward the board;
a housing positioned over a side opposite the board relative to the heat sink, the housing having a facing wall facing the heat sink;
a fan configured to supply wind to the heat sink along the facing wall;
a heat generator, separate from the coupling device, disposed over the board and positioned upstream of the movable part in a wind flowing direction;
a heat transfer member thermally coupled to the elastic part and the heat generator;
a first heat sink thermally coupled to the heat transfer member and the heat generator; and
a second heat sink thermally coupled to the heat transfer member.

2. The information processing device according to claim 1 , wherein the first heat sink is positioned upstream of the second heat sink in a wind flowing direction.

3. The information processing device according to claim 1 , wherein the heat generator is positioned upstream of the second heat sink in a wind flowing direction, and the second heat sink is disposed relative to the heat generator in a direction perpendicular to the wind flowing direction in plan view of the board.

4. The information processing device according to claim 1 , wherein the first heat sink is positioned on a top surface of the heat generator.

5. The information processing device according to claim 4 , wherein the heat transfer member is a heat pipe.

6. The information processing device according to claim 1 , wherein the contact portion is a projecting portion that projects toward the board relative to the top wall.

7. A board device comprising:
a board;
a receiver that includes a top wall facing the board, the receiver configured to allow a coupling device to be inserted into a space between the board and the top wall;
a movable part provided in the top wall, the movable part configured to be movable in a direction facing the board, the movable part having a contact portion configured to be in contact with a top surface of the coupling device;
an elastic part that has elasticity provided at the movable part, the elastic part urging the movable part toward the board;
a heat generator, separate from the coupling device, disposed over the board and positioned upstream of the movable part in a wind flowing direction;
a heat transfer member thermally coupled to the elastic part and the heat generator;
a first heat sink thermally coupled to the heat transfer member and the heat generator; and
a second heat sink thermally coupled to the heat transfer member.

8. The board device according to claim 7 , wherein the first heat sink is positioned upstream of the second heat sink in a wind flowing direction.

9. The board device according to claim 7 , wherein the contact portion is a projecting portion that projects toward the board relative to the top wall.
