Electronic device

According to one embodiment, an electronic device includes a housing, a circuit board, a thermally radiative section, a first heat generator, a second heat generator, a first heat receiving block, a second heat receiving block, at least one heat pipe including a first end and a second end, a second heat pipe including a third end, a fourth end, and an intermediate portion, and a cutout section provided on the first heat receiving block. The second heat generator is mounted on the circuit board at a position farther from the thermally radiative section than the first heat generator is. The first heat receiving block is provided with a cutout section and is thermally connected to the first heat generator. The second heat receiving block is thermally connected to the second heat generator. The intermediate portion of the second heat pipe passes through the cutout section.

According to one embodiment, an electronic apparatus includes a housing, a partition, a first cooling fan, and a second cooling fan. The partition partitions an inside of the housing into a first chamber and a second chamber. The first chamber communicates with a first inlet, a third inlet, and a first outlet. The second chamber communicates with a second inlet and a second outlet. The first cooling fan locates above the third inlet in the first chamber, and includes a first intake configured to draw air in the first chamber, and a second intake configured to draw air outside the housing through the third inlet, the first cooling fan being configured to discharge the air to a heat sink. The second cooling fan locates in the second chamber and is configured to draw air in the second chamber, and to discharge the air to the second outlet.

According to one embodiment, the electronic device includes a housing, the first to third printed circuit boards, and a fan unit. The first printed circuit board includes the first heat-generating part secured to the first wiring board. The second printed circuit board includes the second and third heat-generating parts, has an amount of heat generation larger than that of the first printed circuit board, and is located between the first printed circuit board and the second wall. The third printed circuit board includes the fourth heat-generating part, has an amount of heat generation smaller than that of the first printed circuit board, and is located between the first printed circuit board and the first wall.

An electronic apparatus including: a body; a circuit board housed in the body; a heating body mounted on the circuit board; a heat pipe having: an end portion, a heat emitting portion located on an opposite side to the end portion, and a heat receiving portion located between the end portion and the heat emitting portion and thermally connected to the heating body; a bonding member disposed between the heating body and the heat receiving portion and that bonds the heating body and the heat receiving portion; and an extension that extends toward the circuit board.

According to one embodiment, a heat sink includes first and second fin units. Fins of the first fin unit are provided with a through-hole part in which a heat pipe is inserted. Fins of the second fin unit are provided with a cutout part cut out to avoid the heat pipe. The fins of the second fin unit are inserted in spaces between the fins of the first fin unit. The fins of the second fin unit reach to a region in which the fins of the second fin unit overlap the heat pipe in the first fin unit.

According to one embodiment, an electronic device includes a housing including an opening, a partition wall which partitions an interior part of the housing into a first chamber and a second chamber which is opened to the outside through the opening, first and second heat generating parts mounted in the first chamber, a first heat radiation member located in the second chamber, a heat transfer member which transfers heat generated by the first heat generating part, a cooling fan which draws outside air and exhausts the air against the first heat radiation member, a second heat radiation member which is exposed to the outside of the housing and is thermally connected to the second heat generating part, and a cover covering the opening and the second heat radiation member. The cover forms a gap between the cover and the housing. The gap communicates with the second chamber.

An electronic apparatus has a housing which is formed with a suction port and an exhaust port. The interior of the housing is partitioned with a first chamber and a second chamber by a partition wall. The first chamber accommodates a CPU generating heat. The suction port and the exhaust port are open to the second chamber. A heat pipe which transfers a heat of the CPU from the first chamber to the second chamber is disposed pass through the partition wall. A fan is disposed in the second chamber. The fan suctions air from the suction ports and discharges the suctioned air from the exhaust port. The heat of the CPU transferred to the second chamber is emitted out of the housing. A part where the heat pipe pass through the partition wall is liquid-tightly sealed through a sealing member.
