Abstract

A heat sink, cooling member, semi-conductor substrate cooling system, computer and method for providing sufficient cooling performance through a heat sink is provided. In part, there is provided a heat sink having a radiating portion for diffusing the heat conducted from a heat source and a blasting fan for blasting air to a duct-like structure formed by the radiating portion. Moreover, rates of airflows in the duct-like structure are averaged so that air circulates through all portions in the duct-like structure by forming a high-wind-pressure portion and a low-wind-pressure portion having wind pressures different from each other when air is blasted by the blasting fan in the duct-like structure and using the high-wind-pressure portion as a high-density area having a high arrangement density of radiating fins compared to the low-wind-pressure portion.
