Cooling unit, electronic apparatus, and guide member

摘要

Cooling is performed efficiently by constituting: a fan which is provided with an outlet; a heatsink which is provided with an inlet with a larger size than that of the outlet of the fan in a height direction and through the interior of which an airflow generated by the fan passes; and a guide member which is disposed between the fan and the heatsink and which is configured to guide the airflow to an outer surface of the heatsink.

1. A cooling unit mounted in a package of an electronic apparatus comprising:
a fan provided with an outlet; a heatsink, including a plurality of heat-dissipating fins standing parallel to one another and straightening vanes covering gaps between each adjacent pair of the heat-dissipating fins at one end of each of the heat-dissipating fins, the heatsink being provided with an inlet having a larger size than that of the outlet of the fan in a height direction, an airflow generated by the fan passing through an interior of a first space surrounded by each adjacent pair of the heat-dissipating fins and one surface of each of the straightening vanes; and a guide member disposed between the fan and the heatsink, the guide member guiding the airflow to a second space surrounded by another surface of each of the straightening vanes and the package.
