Abstract

According to an embodiment, an electronic device includes a heat source, a discharge path, a wall internal space, and a heat conductor. The discharge path is configured to guide a gas toward the outside of the device. The wall internal space is surrounded by walls, extends vertically, and is open to a space outside the device via an upper opening and a lower opening that are in different vertical positions. The heat conductor includes a heat absorber that is positioned in the discharge path and a heat dissipater that is positioned in the wall internal space.
