摘要:
An electronic device may have a housing in which electronic components are mounted. The electronic components may be mounted to a substrate such as a printed circuit board. A heat sink structure may dissipate heat generated by the electronic components. The housing may have a housing wall that is separated from the heat sink structure by an air gap. The housing wall may have integral support structures. Each of the support structures may have an inwardly protruding portion that protrudes through a corresponding opening in the heat sink structure. The protruding portions may each have a longitudinal axis and a cylindrical cavity that lies along the longitudinal axis. Each of the support structures may have fins that extend radially outward from the longitudinal axis.
摘要:
An electronic device may have electronic device housing structures in which electronic components such as integrated circuits and connectors may be mounted. The electronic device housing structures may include an upper housing having a planar upper surface member and four perpendicular housing sidewall structures. The housing sidewall structures of the upper housing may have edges that form a rectangular opening with curved corners. A lower housing may have structures forming a rectangular lip that is configured to be received within the rectangular opening in the upper housing. Engagement structures such as inwardly protruding hook structures on the upper housing and snap structures on the rectangular lip may be used in attaching the upper and lower housings. The snap structures may each have a rectangular main opening and lateral extension portions that extend the width of the main opening along the edge of the lip.
