Abstract: A heat dissipation structure adapted to dissipate heat from a heat generating component includes a central housing and a first wing housing. The central housing includes a top portion and a bottom portion opposite to each other, an internal space located between the top portion and the bottom portion, and a first opening communicating with the internal space. The top portion includes multiple through holes. The bottom portion is connected to the heat generating component. The first wing housing is connected to the central housing and includes a first entrance distant from the central housing and communicating with the first opening. The first entrance has a dimension larger than the first opening. An air flow sequentially flows through the first entrance, the first opening, and the internal space and flows out from the through holes.

Abstract: A hinge has a pintle, a spacer assembly, a stationary bracket and a rotating bracket. The pintle is mounted through the spacer assembly and is connected to the stationary and rotating brackets. The spacer assembly has multiple spacers stacked with each other. Each spacer has a ring segment and a bearing segment. The ring segment is mounted around the pintle. The bearing segment has an absorbing space to absorb the stress acting on the ring segment. Therefore, the spacer sustains less stress to prevent breakage easily and a lifespan of the spacer is extended. Therefore, the hinge has a longer lifespan.
