HEAT SINK PROVIDED WITH CENTRIFUGAL FAN

摘要

A heat sink having a centrifugal fan is provided with a cover (2) having an air inlet (10) and an air outlet (11); a bottom section (3) engaged with the cover (2); a heat dissipating fin section (5), which is thermally connected with the bottom section (3), provided with an air inflow section (12) and is composed of a plurality of fin sections; a centrifugal fan (4), which takes in the air from the air inlet (10), and permits the heat dissipating fin section (5) to generate an air flow and generates an air flow toward the outlet (11) along the inner wall of the cover (2); and a heat transfer member (23), which is arranged to reduce the resistance of the air flow generated toward the side of the heat dissipating fin section (5) and transfers heat from the bottom section (3) by being inserted into the fin sections.
