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. 1shows a conventional heat-dissipating device for a memory module. The heat-dissipating device1acomprises two heat-dissipating pieces10a. The two heat-dissipating pieces10aface 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 pieces10a. Each of the two heat-dissipating pieces10ais formed with a fastening mechanism20a. The fastening mechanism20acomprises a hook21aand a locking trough22acorresponding to the hook21a. The two heat-dissipating pieces10aare engaged with each other by means of the fastening mechanism20a/

In order to assemble the heat-dissipating device1a, the hook21aprovided in one of the heat-dissipating pieces10ais engaged in the locking trough22aprovided in another heat-dissipating piece10a, whereby the two heat-dissipating pieces10acan be engaged with each other. Then, the two heat-dissipating pieces10aspread outwards to allow a memory to be disposed therebetween. Since the two heat-dissipating pieces10aare engaged with each other by means of the engagement between the hooks21aand the locking troughs22ain a vertical direction, the hooks21amay be separated from the locking troughs22ain the vertical direction when the two heat-dissipating pieces10aspread outwards. As a result, the two heat-dissipating pieces10aneed 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.
