HEAT SPREADER AND HEAT DISSIPATION DEVICE USING SAME
First Claim
1. A heat dissipation device comprising:
- a heat spreader comprising a main plate and an end cover coupling to one lateral side of the main plate, the main plate defining a plurality of parallel through holes therein, each of the through holes having an open end facing the lateral side of the main plate, a plurality of wick structures being respectively disposed in the through holes, the end cover sealing the open ends of the through holes to form a plurality of hermetical channels in the spreader, a working medium being contained in each of the channels; and
a plurality of fins arranged on a surface of the main plate perpendicular to the lateral side.

Abstract
A heat dissipation fan includes a fan frame, a bearing assembly, a stator and a rotor. The fan frame includes a base and a central tube. The central tube includes an open top end and an open bottom end. The base defines a receiving concave at a bottom surface thereof. The receiving concave communicates with the central hole. A top wall is formed by the base over the concave. A sidewall is formed between the top wall and the bottom surface of the base and surrounds the concave. A plurality of first locking units extend from the top wall into the receiving concave. The bearing assembly includes an oil sealing cover for sealing the open bottom end of the central tube. The oil sealing cover includes a plurality of second locking units which are detachably interlocked with the first locking units to mount the oil sealing cover to the base.
