Embodiment Construction

[0013]Referring to FIG. 1, a cooling device for dissipating heat generated by electronic components 13 of an add-on card 10 is shown. The add-on card 10 can be a memory module, a display card, a sound card, a network interface card, etc. In the shown preferred embodiment, the add-on card 10 is a memory module such as a DRAM module.

[0014]Referring to FIG. 2, in this embodiment, the add-on card 10 is elongated and rectangular. The electronic components 13 are arranged on both of top and bottom sides of the add-on card 10. A plurality of electrical contacts (golden fingers) 120 are formed on a front side 12 of the add-on card 10 adapted for electrically connecting with a socket of an electronic device, such as a computer, which incorporates the add-on card 10. Four cutouts 110 are defined in a rear side 11 of the add-on card 10 opposite to the front side 12. The cutouts 110 are spaced from each other. A slot 14 is defined in each of a left end and a right end of the add-on card 10.

Abstract

A cooling device for cooling an add-on card includes a heat absorption member attached to the add-on card to absorb heat therefrom, a heat sink and a clip for clasping the heat sink onto the heat absorption member. The heat sink includes a supporting plate, and a first plate and a second plate respectively extending from opposite sides of the supporting plate and attached to the heat absorption member tightly. The clip includes an operation board, and an engaging board and a supporting board respectively extending from opposite sides of the supporting plate. The engaging board and the supporting board respectively abut the first plate and the second plate of the heat sink. A tongue extends from the engaging board rearwards and downwards toward the operation board. The tongue is provided for blocking a separation of the clip from the heat sink.

Description

BACKGROUND[0001]1. Technical Field[0002]The disclosure generally relates to cooling devices for add-on cards, and more particularly to a cooling device having a clip for clasping the cooling device onto an add-on card.[0003]2. Description of Related Art[0004]Advances in microelectronics technology have resulted in add-on cards of electronic devices, such as computers, which process signals and data at unprecedented high speeds. During operation of many contemporary add-on cards, a large amount of heat are produced, and a heat sink is usually mounted onto the add-on card to efficiently remove the heat to prevent the electronic device from becoming unstable or being damaged.[0005]Generally, the heat sink includes a first heat absorbing plate, a second heat absorbing plate and a connecting portion interconnecting the first plate and the second heat absorbing plate. The add-on card is sandwiched between and thermally contacts with the first and second heat absorbing plates with a latera...
