1. A vapor chamber, comprising:
a sealed enclosure comprising:
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;
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,
wherein 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,
wherein the distal portions of the first elongate chamber and the second elongate chamber are disposed outside a footprint of a heat dissipation structure disposed on an exterior surface of the vapor chamber.
