1. Technical Field
The present disclosure relates to a heat sink assembly.
2. Description of Related Art
A layer of thermal grease is generally attached to a bottom of a heat sink to improve heat conductivity between an electronic component and the heat sink. A grease cover is mounted to a bottom plate of the heat sink and covers the thermal grease, to protect the thermal grease. The grease cover engages with the bottom plate of the heat sink. However, the grease cover is easily deformed, so the grease cover cannot be recycled.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
The grease cover 10 includes a rectangular main body 11. The main body 11 includes two opposite sidewalls 12. A receiving recess 13 is defined in a top surface of the main body 11. Two blocks 15 extend from opposite ends of each sidewall 12. A recess 16 is defined in a top surface of each block 15. A magnet 18 is pasted on a bottom wall of each recess 16.
The heat sink 20 includes a substantially H-shaped bottom plate 21. A layer of thermal grease 22 is attached to a center of a bottom surface of the bottom plate 21. Four ferromagnetic fasteners 23, such as four screws, are respectively mounted to four corners of the bottom plate 21, with bottom ends of the fasteners 23 extending out of the bottom surface of the bottom plate 21.
The grease cover 10 is attracted to the heat sink 20 by the magnets 18. When the grease cover 10 is detached from the heat sink 20, the grease cover 10 will not be damaged. Therefore, the grease cover 10 can be recycled.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
