A board shield () covers a region in which an electronic part is mounted on a lower surface of a circuit board (). A memory housing chamber (R) capable of housing a semiconductor memory is secured on the lower side of the circuit board. The board shield () includes a shield wall () along the memory housing chamber (R). With this, it is possible to protect the semiconductor memory while suppressing an increase in the number of parts.

Electronic apparatus

A leakage of electromagnetic waves is suppressed effectively on the periphery of a heat radiating device. A heat radiating device () includes a plurality of fins () that are arranged on the inside of an opening (), a heat pipe () that includes a connecting portion () being located between the plurality of fins () and a circuit board () and extending in a left-right direction along the circuit board (), and a base plate () that supports the plurality of fins (). The base plate () includes a plate left portion (). The plate left portion () covers a lower surface of the heat pipe (), the lower surface facing a side of a board shield (), and closes a gap (G) between a left end of the plurality of fins () and a left edge of the opening () of the board shield ().

Electronic device

A heat sink includes a plurality of fins arrayed in a first direction, and a heat pipe having a first extension extending in the first direction. A second direction extends perpendicularly to the first direction, a third direction extends perpendicularly to the first direction and the second direction, and when the heat pipe is viewed in the third direction, the heat pipe has a second extension spaced from the first extension in the second direction and extending in the first direction, and a joint which interconnects the first extension and the second extension and which is curved. The fins include a plurality of first fins arrayed along the first extension and the second extension and a second fin disposed around a position of the joint.

Heat sink and electronic device

Recording and data storage medium

Electronic apparatus includes a housing configured to have an inner layer portion forming an inner surface and an outer layer portion forming an outer surface. The inner layer portion and the outer layer portion are formed by two-color molding. The electronic apparatus includes one of a region in which the inner layer portion is not formed and a region in which the inner layer portion is thin. The one region is set in the inner surface of the housing. The electronic apparatus further includes a component configured to be housed in the housing and is disposed in the one region.
