Field of the Invention The present invention relates to a heat sink, and more particularly to a heat sink with a heat shield. [Prior Art] When using a heat sink to dissipate heat from an electronic component, in order to improve the heat transfer capability between the heat sink and the electronic component, a heat transfer medium (such as #thermal adhesive) is usually applied on the bottom surface of the heat sink. However, since the heat conductive medium easily contaminates the peripheral components It is not contaminated by dust and other particles and cannot be applied to the radiator in advance. Typically, the heat transfer medium is applied to the diffuser when the heat sink is mounted to the central processor. In order to overcome the above problems, a variety of heat-conducting medium protection devices have been proposed. For example, U.S. Patent No. 6,049,458 discloses a heat-conducting medium protection device which is disposed on the bottom surface of a heat sink coated with a heat-conducting medium to prevent heat conduction. During the handling and installation process, other components are contaminated and contaminated. Through the V heat medium protection device, the heat transfer medium can be applied to the heat sink in advance, simplifying the step of mounting the heat sink to the central processor. However, the heat medium protection device is Adhesive is attached to the bottom surface of the heat sink. When the heat sink is mounted to the central processing unit, the glue removal work is required, which is inconvenient, and the adhesive easily loses its viscosity after being used for many times. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a heat dissipating device whose heat conducting medium protection cover can be conveniently mounted and detached. 7 200839491 A heat dissipating device comprising a heat sink, a heat conductive medium coated on the heat sink, and a heat conductive medium protection cover that is interference fit on the heat sink; the heat medium protection cover includes a heat medium protection a body of the space and a first corner connected to the body and covering a corner end of the heat sink; the first corner has two adjacent sides and a pair of sides γ each adjacent to the two adjacent sides Extending a first solid side edge that cooperates with a side wall of the corner end of the heat sink; the first corner portion is rotatably coupled to the body with opposite sides thereof so that the corner portion of the first corner can be flipped relative to the body . The above-mentioned ¥ heat medium protective cover is assembled to the heat sink by means of an interference fit, and the operation is more convenient than the existing adhesive bonding method, and the assembly can be repeated a plurality of times. In addition, since the first corner of the heat-conducting medium protection cover is movably connected to the body, the interference between the heat-preserving bonnet and the heat-dissipating n is easily removed during the disassembly process, so that the disassembly is more convenient and safe.

The heat-dissipating consultation 10 is made of a material such as copper, fame, and J aluminum temple having good thermal conductivity, which includes a pedestal and a symmetrical heart and a right-hand heat-releasing fin 13 . In the actual target example, the susceptor n is generally in the shape of a rectangular half-lifted plate, which has a bottom surface (not labeled) and a fishing rod for the electronic component, & The bottom surface is opposite to the top surface (not labeled). The ..., , , and Japanese sheets 13 are in the form of a sheet, and the parallel portions 8 1 are arranged on the top surface of the susceptor 11, 200839491 _ to increase the contact area with the air. A heat conductive medium 30 (for example, a thermal conductive adhesive) is uniformly applied to the bottom surface of the susceptor 11 for thermally connecting the bottom surface of the susceptor 11 to the electronic component to improve the thermal conductivity between the susceptor 11 and the electronic component. The heat transfer medium protective cover 20 is mounted on the base 11 of the heat sink 10 and covers the heat transfer medium 30 to prevent the heat transfer medium 30 from being contaminated or damaged by the outside. The heat conductive medium protection cover 20 is generally integrally formed of a plastic material, and includes a flat body 21 and a first corner portion 210 and a second corner portion 212 connected to the body 21, and the second corner portion 212 and the first portion The corners 210 are distributed at diagonal positions of the heat transfer medium protection cover 20. The body 21 protrudes toward a side of a cover body 214. The cover body 214 forms a heat-conducting medium protection space for resisting damage to the heat-conductive medium 30 by an external force. The size of the heat-conductive medium protection space depends on the size of the heat-conductive medium 30. The first corner portion 210 has two adjacent sides (not labeled) and a pair of opposite sides (not labeled) connecting the two adjacent sides. The two adjacent sides are perpendicular to each other and equal in length, and respectively protrude in a direction opposite to the cover body 214. The direction of the first fixed side edges 240, 250 extends perpendicularly to the side walls of the base 11 of the heat sink 10, and the first fixed side edges 240, 250 are connected to each other at adjacent end edges. The second corner portion 212 is integrally formed with the body 21 and has two adjacent sides. Each of the adjacent sides extends in the same direction as the first fixed side edges 240 and 250 to extend a second fixed side for engaging with the heat sink 10 . Edge 22, 23. The second fixed side edges 22, 23 are perpendicular to each other and are parallel to the first fixed side edges 250, 240, respectively, and the adjacent end edges of the second fixed side edges 22, 23 are also connected to each other. The first fixed side edges 240, 250 and the second fixed side edges 22, 23 define a mating space for accommodating the base 11 of the heat sink 10. The size of the mating space is slightly smaller than the base of the heat sink 10 200839491 11 The dimensions are such that the thermally conductive medium protective cover 20 can be assembled to the base 11 of the heat sink 10 by an interference fit. In this embodiment, in order to facilitate the disassembly of the heat-conducting medium protection cover 20, the first corner portion 210 is movably connected to the body 21 with the opposite sides, so that the first corner portion 210 can be turned around the opposite side 21 with respect to the opposite side. In addition, in order to realize the pre-positioning of the heat-transfer protective cover 20 during installation, the baffles 24 and 25 are further extended on the main body 21 in the same direction as the first fixed side edges 240 and 250, and the two baffles 24 and 25 respectively Parallel to the second fixed side edges 22, 23 described above, such that the second fixed side edges 22, 23 define a pre-mating space for pre-positioning the thermally conductive medium protective cover 20 onto the base 11 of the heat sink 10. The end edge of the baffle 24 adjacent to the second fixed side edge 23 is spaced apart from each other, and the edge of the baffle 25 adjacent to the second fixed side edge 22 is also spaced apart to the other two of the heat-transfer protective cover 2 The diagonal position is notched, so that when the heat conductive medium protection cover 20 is covered on the base 11 of the heat sink 10, the corner ends of the other two diagonal corners of the base 10 are exposed, so that the heat conductive medium protection cover 20 can be conveniently pre-positioned on the base. On the seat 10. _ When assembling, the first corner portion 210 of the heat-conductive medium protection cover 20 is turned up, and then the heat-transfer medium protection cover 20 is sleeved on the base 11 of the heat sink 10, and the second corner portion 212 of the body 21 is covered. One corner end of the base 11 , the first corner portion 210 folded up is correspondingly disposed at the other corner end opposite to the corner end, and the second fixed side edges 22 , 23 of the second corner portion 212 and the body 21 The baffles 24, 24 respectively abut against the four side walls of the base 11, achieving a predetermined position of the heat transfer medium protection cover 20. Finally, the first corner portion 210 is pressed against the heat sink 10, and the first corner portion 210 is sleeved on the other corner end of the base 11 of the heat sink 10. The two diagonal positions of the base 11 of the heat sink 10 are 200839491 The angle between the corner end and the first corner portion 2i of the heat-conducting medium protection cover 2 is over=' such that the first fixed side edge 24〇 of the first corner portion 21〇, the second fixed side of the second brother's 212, The edges 22, 23 and the heat sink 10: a large friction between the upper shell 'soil' will heat the heat 2 . Firmly assembled to the radiator 1〇. When disassembling, firstly remove the first vine part _, and then remove the interference force of the heat transfer medium protection cover 2Q and the heat sink Μ ^ 3 to remove or reduce the friction between the heat transfer medium protection cover 2 〇 /, the soil seat 11 Force 'disassembled is very easy. ^There is an over-filled heat-conducting medium protection 盍20 with a foldable angle-corner, which has the following k points compared with the ordinary interference-fit heat-conductive medium protective cover. When the cover is disassembled, it must be disassembled as a whole, and because the contact area between the protective cover and the heat sink is large, the friction between the protective cover and the heat sink is large, the disassembly is difficult, and the heat transfer medium is easily scraped due to improper use of the force channel. , and the protective cover 2 with the foldable corner-corner 210 can be easily lifted by lifting the first corner to the interference between the 2G and the radiator 1G. Next, during the folding of the first corner end 21〇, the position of the body 21 does not substantially change, so that the heat medium is not scratched due to improper use of the force channel. In addition, the first corner of the present meal 21Q is set to a reversible structure and has its unique advantages, for example, it can be folded up with one hand, without being restricted by the size A of the base 1 of the radiator 1G. Other locations are provided in a foldable configuration. It is relatively difficult to fold the base of the heat sink base 10, which is larger in size, with a protective cover. </ RTI> </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> </ RTI> </ RTI> <RTIgt; Other corners may also be included, and the second corner 212 and other corners may also be provided in a reversible structure.
