Abstract
A method () and an apparatus for manufacturing a heat-dissipation device () with a vacuum chamber and a working fluid therein are disclosed. The method includes the following steps: vacuuming a hollow metal casing () through a first open end () thereof until an interior of the casing reaches a predetermined vacuum degree; sealing the first open end; filling a predetermined quantity of working fluid into the casing through a second open end () thereof; and sealing the second open end. The apparatus includes a vacuum pump, a liquid-storage tank and a set of processing device, as used respectively for the above vacuuming, liquid-filling and sealing steps. By this apparatus, the heat-dissipation device can be manufactured at a same place without the requirement to shift the casing from one place to another place during the manufacture of the heat-dissipation device.
