Chipset cooling device of video graphic adapter card
First Claim
1. A chipset cooling device of a video graphics adapter card, which cools a chipset mounted on a printed circuit board of the video graphics adapter card, the chipset cooling device comprising:
- a first heatsink mounted on the same side as the chipset to dissipate heat generated by the chipset;
a second heatsink mounted on a side opposite to the first heatsink, with the PCB between the first and second heatsink; and
at least one heatpipe which connects the first heatsink and the second heatsink so as to transfer heat from the first heatsink to the second heatsink.

Abstract
A chipset cooling device of a video graphics adapter (VGA) card that includes two heatsinks mounted on respective opposite surfaces of a VGA card to collectively cool a chipset of the VGA card is provided. In the chipset cooling device of a VGA card, two heatsinks are mounted on opposite surfaces of a printed circuit board (PCB) of the VGA card, respectively, and connected together by a heatpipe. Due to the use of two heatsinks to collectively cool a chipset, cooling efficiency is higher as opposed to using a single heatsink. In particular, a binding portion between a heatsink contacting the chipset of the VGA card and the heatpipe is always positioned at a lower level than a binding portion between the other, opposite heatsink and the heatpipe, thereby further enhancing the heat conduction performance of the heatpipe.
