## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a heat-dissipating assembly, and in particular to a heat-dissipating assembly for a memory.
2. Description of Prior Art
With the rapid advancement of science and technology, computer hardware is being developed to have a high operating speed and high frequency to thereby enhance its performance. As a result, the amount of electricity consumed by the computer hardware per second becomes much larger. Thus, the amount of heat generated by the existing electronic elements is relatively larger than before. For example, the operating clock and transmission bandwidth of a memory module becomes larger and larger in order to match a high-speed processor. As a result, the working temperature of the memory module and the amount of heat generated thereby are increased to such a level that the performance of the memory module is deteriorated. Even, the memory module may suffer damage.
FIG. 1 shows a conventional heat-dissipating device for a memory module. The heat-dissipating device 1a comprises two heat-dissipating pieces 10a. The two heat-dissipating pieces 10a face each other to sandwich the surfaces of the memory module. By this structure, the heat generated by the memory module can be dissipated by the two heat-dissipating pieces 10a. Each of the two heat-dissipating pieces 10a is formed with a fastening mechanism 20a. The fastening mechanism 20a comprises a hook 21a and a locking trough 22a corresponding to the hook 21a. The two heat-dissipating pieces 10a are engaged with each other by means of the fastening mechanism 20a/ 
In order to assemble the heat-dissipating device 1a, the hook 21a provided in one of the heat-dissipating pieces 10a is engaged in the locking trough 22a provided in another heat-dissipating piece 10a, whereby the two heat-dissipating pieces 10a can be engaged with each other. Then, the two heat-dissipating pieces 10a spread outwards to allow a memory to be disposed therebetween. Since the two heat-dissipating pieces 10a are engaged with each other by means of the engagement between the hooks 21a and the locking troughs 22a in a vertical direction, the hooks 21a may be separated from the locking troughs 22a in the vertical direction when the two heat-dissipating pieces 10a spread outwards. As a result, the two heat-dissipating pieces 10a need to be assembled again, and thus the assembly thereof requires more time and work.
In order to solve the above-mentioned problems, the present Inventor proposes a novel and reasonable structure based on his expert knowledge and delicate researches.

The present invention provides a memory device 1, which comprises a memory 10 and a heat-dissipating assembly 20 configured for heat dissipation of the memory 10.
The heat-dissipating assembly 20 includes a first heat-dissipating body 30 and a second heat-dissipating body 40. The first heat-dissipating body 30 is adhered to one side of the memory 10. The bottom edge of the first heat-dissipating body 30 has a first supporting piece 31 bent toward the memory 10. The first supporting piece 31 has a pair of engaging pieces 32. Each of the engaging pieces 32 comprises a first stopping section 321 extending outwards from the first supporting piece 31 and a first insertion section 322 perpendicular to the first stopping section 321.
The second heat-dissipating body 40 is adhered to the other side of the memory 10 to correspond to the first heat-dissipating body 30. The bottom edge of the second heat-dissipating body 40 has a second supporting piece 41 bent toward the memory 10. The second supporting piece 41 has a pair of second engaging pieces 42. Each of the second engaging pieces 42 comprises a second stopping section 421 extending outwards from the second supporting piece 41 and a second insertion section 422 perpendicular to the second stopping section 421. The second insertion section 422 extends toward the first insertion section 322.
According to the above, the first supporting piece 31 is provided with a first notch 310 at an inner edge of the first stopping section 321. The second supporting piece 41 is provided with a second notch 410 at an inner edge of the second stopping section 421. The first supporting piece 31 is formed with a first retaining piece 311 at an outer edge of the first stopping section 321. The second supporting piece 31 is formed with a second retaining piece 411 at an outer edge of the second stopping section 421.
In the present embodiment, each of the first engaging piece 32 and the second engaging piece 42 is substantially formed into an L shape. In the first engaging piece 32, each of the first stopping section 321 and the second stopping section 421 is formed a stepped shape. The first stopping section 321 comprises a first bent surface 3211 and a first planar surface 3212 connected to the first bent surface 3211.
