Abstract
A cooling unit having a fan and a heat sink thermally connected to a heat generating component. The heat sink includes a receptacle in which the fan is contained, a plurality of air paths which are arranged to surround an outer peripheral portion of the fan, and through which the air exhausted from the outer peripheral portion flows, and at least one partition which divides the respective air paths into a plurality of regions. The partition extends toward a downstream of the air paths from the outer peripheral portion of the fan.
Claims21
A cooling unit which cools a heat generating component, comprising:
- a fan having an outer peripheral portion to exhaust air;
- and
- a heat sink which is thermally connected to the heat generating component, the heat sink including:
- a receptacle in which the fan is contained;
- a plurality of air paths which are arranged to surround the outer peripheral portion of the fan, and through which the air exhausted from the outer peripheral portion flows;
- and at least one partition which divides each air path into a plurality of regions, and extends toward a downstream of the air paths from the outer peripheral portion of the fan.
A cooling unit which cools a heat generating component, comprising:
- a fan impeller having an outer peripheral portion to exhaust air;
- and
- a heat sink which is thermally connected to the heat generating component, the heat sink including:
- a receptacle in which the fan is contained;
- first and second outlets opened in positions different from each other with respect to the fan;
- first and second air paths which extend toward the first and second outlets from the outer peripheral portion of the fan;
- at least one guide wall which is disposed in the receptacle, and moves toward the outer peripheral portion of the fan to distribute the air exhausted from the outer peripheral portion into the first and second air paths;
- and a plurality of partitions which are disposed in the first and second air paths, and extend toward the first and second outlets from the outer peripheral portion of the fan.
A cooling unit which cools a heat generating component, comprising:
- a fan having an outer peripheral portion to exhaust air;
- and
- a heat sink which is thermally connected to the heat generating component, the heat sink including:
- a receptacle in which the fan is contained;
- first and second outlets opened in positions different from each other with respect to the receptacle;
- first and second air paths which connect the receptacle to the outlets, and include upstream ends disposed opposite to each other via the fan;
- and at least one partition which divides the first and second air paths into a plurality of regions.
An electronic apparatus comprising:
- a housing including a heat generating component;
- and
- a cooling unit which is contained in the housing, and cools the heat generating component, the cooling unit including:
- a fan having an outer peripheral portion to exhaust air;
- and
- a heat sink which is thermally connected to the heat generating component, the heat sink including:
- a receptacle in which the fan is contained;
- a plurality of air paths which are arranged to surround the outer peripheral portion of the fan, and through which the air exhausted from the outer peripheral portion flows;
- and at least one partition which divides the air paths into a plurality of regions, and extends toward a downstream of the air paths from the outer peripheral portion of the fan.
