Abstract

An electronic apparatus includes a first board, a second board, a housing, and a first thermal conductive assembly. The housing accommodates the first board and the second board. The first thermal conductive assembly connects a face of the first board, the face of the first board fronting a region between the first board and the second board, to a first face of the housing or a second face of the housing. The first face is opposed to the first board, the second face is opposed to the second board.

Claims (29)

1. An electronic apparatus comprising:

a first hoard;

a second board;

a housing that accommodates the first board and the second board; and

a first thermal conductive assembly that connects a face of the first board, the face of the first board fronting a region between the first board and the second board, to a first face of the housing or a second face of the housing, the first face being opposed to the first board, the second face being opposed to the second board.

2. The electronic apparatus according to claim 1 , wherein the first thermal conductive assembly has a hook shape.

3. The electronic apparatus according to claim 2 , wherein the first thermal conductive assembly includes a thermal conductive element that includes a first contact portion set in contact with the first board in the region between the first hoard and the second board, a second contact portion set in contact with the first face of the housing or the second face of the housing, and a connecting portion connecting the first contact portion to the second contact portion.

4. The electronic apparatus according to claim 3 , wherein the second board includes an opening at a position corresponding to an arrangement position of the second contact portion.

5. The electronic apparatus according to claim 4 , wherein the first thermal conductive assembly further includes a fixing part for fixing the thermal conductive element to the opening of the second board.

6. The electronic apparatus according to claim 1 , wherein

the first board includes a device that generates heat, and

the first thermal conductive assembly is arranged correspondingly to a position of the device that generates heat.

7. The electronic apparatus according to claim 6 , wherein

the first board or the second board further includes a nonvolatile memory,

the device that generates heat is a controller for controlling the nonvolatile memory, and

the first thermal conductive assembly is arranged on a reverse side of a mounting position of the controller on the first board.

8. The electronic apparatus according to claim 6 , wherein the first thermal conductive assembly is set in contact with the device that generates heat.

9. The electronic apparatus according to claim 3 , wherein the first contact portion is set in contact with the second board.

10. The electronic apparatus according to claim 3 , wherein

the second board includes a device that generates heat, and

the first contact portion is set in contact with the device.

11. The electronic apparatus according to claim 3 , wherein

the first board includes a first device that generates heat,

the second board includes a second device that generates heat, and

the first contact portion is set in contact with the first device and the second device.

12. The electronic apparatus according to claim 1 , further comprising:

a third board; and

a second thermal conductive assembly that connects a face of the third board, the face of the third board fronting a region between the first board and the third board; to the first face of the housing or the second face of the housing.

13. The electronic apparatus according to claim 1 , wherein the first thermal conductive assembly includes aluminum, copper, or a heat pipe.
