According to various embodiments of the present disclosure, an electronic device may include a first housing, a second housing connected to the first housing via a hinge structure, an electronic component, a flexible display being configured to be foldable according to rotation, a heat dissipation sheet arranged under the flexible display, and a first adhesive layer configured to bond the flexible display and the heat dissipation sheet to each other. The heat dissipation sheet may include a first portion corresponding to the first housing, a second portion corresponding to the second housing, and a third portion interconnecting the first portion and the second portion and corresponding to the hinge structure. The third portion may include a structure that protrudes or is folded at least once with respect to the first portion and the second portion. The first adhesive layer may include a first opening corresponding to the third portion.

Electronic device including foldable display

An electronic device includes a printed circuit board ('PCB') structure which accommodates a thermal interface material (“TIM”). The PCB structure includes a base plate, a first component on the base plate, a second component on the base plate and apart from the first component, an interposer connected to the base plate and surrounding the first component and the second component, a cover plate connected to the interposer and covering the first component and the second component, and an accommodation part which is between the base plate and a heat conduction plate and accommodates the TIM.

Electronic device including printed circuit board structure including thermal interface material

The disclosure relates to an electronic device including: a circuit board; a first component disposed on the circuit board; a shield can disposed to surround at least a part of the first component and including an opening; and a nanofiber film disposed on the shield can to cover the opening, wherein the nanofiber film includes a first layer, a second layer, and a third layer sequentially laminated in a first direction, the first layer or the third layer having a lower electrical resistance value than an electrical resistance value of the second layer in a second direction different from the first direction, and the second layer has a lower electrical resistance value than an electrical resistance value of the first layer or the third layer in the first direction.

Electronic device including sheilding structure

The disclosure relates to a wireless charging device including a cooling fan, and the wireless charging device according to an embodiment of the disclosure includes: a housing including a holding portion configured to hold an external electronic device; a first bracket positioned in the holding portion; a conductive coil disposed in the first bracket; a second bracket positioned in the holding portion and including a penetrating hole; a first cooling fan positioned in the penetrating hole; a second cooling fan positioned in the penetrating hole and spaced apart from the first cooling fan; and a partition formed in the penetrating hole to isolate the first cooling fan and the second cooling fan from each other, the penetrating hole being divided into a first area having the first cooling fan disposed therein and a second area having the second cooling fan positioned therein, at least one protrusion having a volute shape formed on at least a portion of the second bracket or at least a portion of the partition, a first opening formed on at least an area of the first bracket to allow air cooled by the first cooling fan and/or the second cooling fan to move to the holding portion, and a second opening formed on at least an area of the holding portion to allow the air transmitted from the first opening to move outside the wireless charging device.

Method for controlling cooling fan and wireless charging device

A portable communication device is provided. A portable communication device includes a first nanofiber member having a first density, a second nanofiber member attached to the first nanofiber member and having a second density lower than the first density, a heat transfer member positioned on or above the second nanofiber member, and a conductive material coated on at least a portion of the first nanofiber member and the second nanofiber member. At least some of the conductive material may penetrate into the first nanofiber member or the second nanofiber member. Various other embodiments may be possible.
