Abstract

An electronic device includes a housing that has a bottom surface and a side surface and includes an opening for air cooling formed therein; and a substrate that has a heat generating component mounted on a surface thereof facing the bottom surface of the housing and is fixed in the housing such that there is space between the substrate and the opening. The electronic device further includes a heat radiation component that contacts the heat generating component on the substrate and that spreads, between the bottom surface of the housing and the substrate, through the space, and to a position near and inside the opening; and a fan that is disposed in the space and fixed in the housing independently of the substrate so as to perform air cooling using the opening.
