Abstract
The present invention relates to aheat-dissipating device, which comprises an upper part and a lower part. The upper part further includes an inner joining face and an outer face opposite the inner joining face and the lower part further includes a concave surface which is engaged with the inner joining face of the upper part to form an air-tight chamber with a suitable quantity of circulating liquid being filled therein. The concave surface of the lower part further includes a plurality of capillary trenches and at least one basin, wherein each capillary trench connects the basin and further grid-like trenches are formed inside the basin in order to enhance vaporizing efficiency of the circulating liquid.

A heat-dissipating device, comprising:
- an upper part, further including a joining face and an outer face opposite said joining face;
- a lower part, further including a concave surface which is engaged with said joining face of said upper part to form an air-tight chamber and has a plurality of capillary trenches and at least one basin, with each said capillary trench connecting said basin and with grid-like trenches being formed inside said basin;
- and
- a circulating liquid, enveloped in said air-tight chamber to perform the circulating progress of liquid/vapor phase transformation.
