DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present invention provides a heat-dissipating, shock-absorbing structure 1 which is applicable to an electronic module. FIG. 1 and FIG. 2 are schematic views of how the heat-dissipating, shock-absorbing structure 1 in the first embodiment of the present invention is coupled to a hard disk drive 21 of an electronic module (not shown). In the first embodiment, the heat-dissipating, shock-absorbing structure 1 comprises two heat-dissipating frames 11, a plurality of elastomers 12, and a plurality of heat conduction layers 13. The description below explains how components of the heat-dissipating, shock-absorbing structure 1 relate to an electronic module.

[0023] The heat-dissipating frames 11 are disposed on two opposing sides 213 of the hard disk drive 21, respectively. Since both the heat-dissipating frames 11 connect with the hard disk drive 21 in the same way, the first embodiment illustrates how one of the heat-dissipating frames 11 connects with the hard disk drive 21 for the sake of brevity. The heat-dissipating frame 11 has a fixing segment 111 and two extending segments 112. The fixing segment 111 is connected between the extending segments 112 such that the heat-dissipating frame 11 is U-shaped. The fixing segment 111 and the extending segments 112 jointly define a receiving space S such that the hard disk drive 21 is partially received in the receiving space S. The fixing segment 111 and the extending segments 112 jointly define an opening. The opening opens in an opening direction D to face the hard disk drive 21. The fixing segment 111 connects with the sides 213 of the hard disk drive 21. The extending segments 112 extend to an upper surface 211 and a lower surface 212 of the hard disk drive 21, respectively. A distance H between the extending segments 112 is greater than a thickness T of the hard disk drive 21. Therefore, as shown in FIG. 2, the extending segments 112 extend to the upper surface 211 and the lower surface 212 of the hard disk drive 21, respectively, such that a gap P is formed between the upper surface 211 and the lower surface 212. The upper surface 211 and the lower surface 212 each define two lateral zones A2 and a central zone Al between the lateral zones A2; hence, the extending segments 112 extend to the lateral zones A2, respectively, such that the gap P is formed between the extending segments 112 and the lateral zones A2.

[0024] Referring to FIG. 2, the heat conduction layers 13 enclose the elastomers 12, respectively, such that the heat conduction layers 13 and the elastomers 12 are disposed at the extending segments 112. Therefore, the heat conduction layers 13 are partially disposed between the heat-dissipating frame 11 and the elastomers 12, respectively. Referring to FIG. 3, after the heat-dissipating, shock-absorbing structure 1 and the hard disk drive 21 have been put together, they are placed in a casing 22 of an electronic module. Then, the casing 22 is placed in an internal space of the electronic device. Therefore, heat generated from the hard disk drive 21 is transferred from the sides 213 of the hard disk drive 21 to the fixing segment 111 and the extending segments 112, even proceeds to the heat conduction layers 13, and is finally dissipated through the casing 22. Therefore, enclosure by the heat conduction layers 13 solves the problem with the low thermal conductivity of the elastomers 12. In addition, with the hard disk drive 21 being suspended in the air within the heat-dissipating frames 11, the hard disk drive 21 is never subjected to compression which might otherwise cause damage to its components, such as disk platters, a read/write head, and driving motors. Furthermore, the elastomers 12 disposed at the extending segments 112 absorb shocks and thus protect the hard disk drive 21 against shocks.

[0025] It is worth noting that the arrangement and quantity of the heat-dissipating frames 11, the elastomers 12, and the heat conduction layers 13 are subject to changes as need. For instance, as shown in FIG. 4, which is a lateral schematic view of how the heat-dissipating, shock-absorbing structure in the second embodiment of the present invention is coupled to the hard disk drive 21, the elastomers 12 are directly disposed at the heat-dissipating frames 11 and in direct contact with the heat-dissipating frames 11 (that is, the elastomers 12 and the hard disk drive 21 are on opposite sides of the heat-dissipating frames 11). In a variant embodiment, the heat conduction layers 13 are provided in the number of one to enclose the elastomers 12 and the heat-dissipating frames 11 concurrently, whereas the heat-dissipating frames 11 or the elastomers 12 are also provided in the number of one as needed. The elastomers 12 may not only be disposed outside the extending segments 112 but may also be disposed at the fixing segment 111 to protect the sides 213 of the hard disk drive 21 concurrently. As shown in FIG. 4, after being enclosed by the heat conduction layers 13, the elastomers 12 are disposed between the extending segments 112 and the upper surface 211 or the lower surface 212 of the hard disk drive 21 (that is, after being enclosed by the heat conduction layers 13, the elastomers 12 are disposed on the same side of the heat-dissipating frames 11 as the hard disk drive 21 is.)

[0026] In this embodiment, the heat-dissipating frames 11, the heat conduction layers 13 and the casing 22 are made of metal, whereas the elastomers 12 are made of foam, but the present invention is not limited thereto. At the very least, the elastomers 12 have a greater elastic modulus than the heat conduction layers 13, whereas the heat conduction layers 13 have a greater coefficient of heat conductivity than the elastomers 12, so as to effectuate heat dissipation and shock absorption anticipated according to the present invention.

[0027] FIG. 5 is a perspective schematic view of how the heat-dissipating, shock-absorbing structure in the third embodiment of the present invention is coupled to the hard disk drive 21. This embodiment is distinguished from the preceding embodiments by technical features as follows: in this embodiment, the extending segments 112 each have a cantilever structure 112a extending to above the central zone Al of the upper surface 211 and the lower surface 212; the cantilever structure 112a is separated from the upper surface 211 and the lower surface 212 by a distance to increase the heat transfer area of the heat-dissipating frames 11; the elastomers 12 are disposed at the extending segments 112, the cantilever structure 112a and the fixing segment 111; and, after being enclosed by the heat conduction layers 13, the elastomers 12 are disposed at the heat-dissipating frames 11. In a variant embodiment, the elastomers 12 are directly disposed at the heat-dissipating frames 11, and then the heat conduction layers 13 enclose the elastomers 12 and the heat-dissipating frames 11.

[0028] FIG. 6 is a perspective schematic view of how the heat-dissipating, shock-absorbing structure in the fourth embodiment of the present invention is coupled to the hard disk drive 21. This embodiment is substantially identical to the first embodiment in structure. This embodiment is distinguished from the preceding embodiments by technical features as follows: in this embodiment, the extending segments 112 and the fixing segment 111 each have a plurality of hollowed-out regions E, respectively. Therefore, this embodiment features the hollowed-out regions E but dispenses with unimportant heat transfer blocks, so as to reduce the weight of the heat-dissipating frames 11 while effectuating heat transfer.

[0029] FIG. 7 is a perspective schematic view of how the heat-dissipating, shock-absorbing structure in the fifth embodiment of the present invention is coupled to the hard disk drive 21. Like the fourth embodiment, the fifth embodiment is characterized in that the extending segments 112 and the fixing segment 111 each have the hollowed-out regions E. This embodiment is distinguished from the preceding embodiments by technical features as follows: in this embodiment, after the fixing segment 111 has connected with the sides 213 of the hard disk drive 21, the extending segments 112 extend outward away from the hard disk drive 21; the extending segments 112 are absent from above and below the upper surface 211 and the lower surface 212 of the hard disk drive 21; hence, the fixing segment 111 and the extending segments 112 jointly define an opening, and an opening direction D of the opening points away from the hard disk drive 21.

[0030] In conclusion, a heat-dissipating, shock-absorbing structure of the present invention comprises: a heat-dissipating frame in which a hard disk drive is suspended in the air, to not only allow the heat-dissipating frame to dissipate heat generated from the hard disk drive in operation, but also provide first-tier protection for the hard disk drive which might otherwise be vulnerable to compression; elastomers for absorbing shocks to provide second-tier protection for the hard disk drive; and heat conduction layers for assisting in dissipating heat generated from the hard disk drive. Therefore, the heat-dissipating, shock-absorbing structure of the present invention achieves heat dissipation and shock absorption concurrently.

[0031] The implementation and technical features of the present invention are illustrated above by preferred embodiments. However, the preferred embodiments are not restrictive of the scope of the present invention. Hence, all changes and equivalent arrangements easily made to the aforesaid embodiments by persons skilled in the art shall fall within the scope of the present invention. Accordingly, the legal protection for the present invention shall be defined by the appended claims.
