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, and is folded at least once around the PCB such that an end portion is connected to the first heatsink and the other end portion is connected 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.
