Abstract: There may be provided a portable electronic device which may include a housing partitioned into a component enclosure portion and a module bay portion. The portable electronic device may include a heat-generating component and a heat-dissipation arrangement disposed within the component enclosure portion of the housing. The heat-dissipation arrangement may include a thermal transfer body in thermal contact with the heat-generating component, a primary thermal conveyance duct, and an auxiliary thermal conveyance duct.

Abstract: In some aspects, a vapor chamber includes a sealed enclosure. The sealed enclosure includes: a main chamber; a first elongate chamber extending laterally from a first side of the main chamber; and a second elongate chamber extending laterally from a second, opposite side of the main chamber. The vapor chamber further includes a first capillary structure lining a first interior surface of the sealed enclosure, and a second capillary structure lining a second, opposite interior surface of the sealed enclosure. Distal portions of the first elongate chamber and the second elongate chamber are configured as reservoirs that store an excess volume of a working fluid in a liquid state when a heat source is in a first operating state, and release the excess volume of the working fluid towards the main chamber when the heat source is in a second operating state.

Abstract: In some aspects, a fan with lighting effect includes a fan blade assembly, a fan frame, a light emitting module, a reflector and a light guide. The fan frame has a periphery structure radially disposed to surround the fan blade assembly, the periphery structure having an inner wall and an outer wall defining a slot therebetween. The light emitting module is disposed in the slot and oriented to emit light along a light path non-parallel with the rotational axis of the fan blade. The reflector is disposed in the slot and in the light path of the light emitting module for reflecting the light emitted by the light emitting module. The light guide is fitted to the slot in a manner to guide light to exit from the slot via the slot opening.
