Dell Laptop Uses New Intel Cooling Technology
Dell's Vostro V130 is one of the first laptops to incorporate Intel's Hyperbaric cooling technology, which uses an internal fan that draws air into the laptop to keep it from overheating. With most existing designs, the internal fans are used to push hot air out.
The air that's pulled in is channeled toward key components to keep them cool, such as the CPU. The air is drawn in through the left side of the laptop, and the warm air is then expelled out the right.
The system allows the fans to run at lower speeds, which results in a quieter laptop, said Rajiv Mongia, a principal engineer at Intel. It also leads to a cooler laptop, according to Intel, because the cooling system is more efficient.
"By using cold air directly from the outside and then directly blowing across the hot components, you create a more efficient cooling solution. This is because by blowing air across the components, you create more intense convective cooling and often get more cooling flow through the platform," Mongia said.
