GREASE PROTECTING APPARATUS FOR HEAT SINK

摘要

A grease protecting apparatus ( 10 ) includes a heat sink ( 12 ), and a grease cover ( 14 ). The heat sink includes a bottom surface ( 122 ) for contacting with a heat-generating component. A layer of thermal grease ( 16 ) is spread on the bottom surface of the heat sink. The grease cover is attached to the bottom surface of the heat sink and covers the grease to protect the grease from contamination. The cover includes a main body ( 142 ) defining a protecting space ( 143 ) therein for covering the grease, and two wings ( 144 ) extending from two opposite sides of the main body for attaching the grease cover to the bottom surface of the heat sink. The wings defines a plurality of perforations ( 148 ) therein to make the wings be capable of tilted upwardly and downwardly.
