ABSTRACT:
A heat-dissipating device includes a hollow heat-transfer member adapted to be disposed on a heat-generating source and confining a vacuum sealed chamber therein, an amount of coolant medium contained in the vacuum sealed chamber for heat exchange, and a plurality of heat-dissipating fins provided on the heat-transfer member. The vacuum sealed chamber has a wider section, a narrower section, and a neck section between the wider and narrower sections. The neck section hampers movement of the coolant medium from the wider section to the narrower section when the heat-transfer member is tilted from an upright position, where the narrower section is disposed above the wider section.
