Cooling unit for cooling heat generating component and electronic apparatus having the cooling unit

A cooling unit for cooling a heat generating component, comprising:

• a heat sink including a heat receiving portion for receiving heat generated by the heat generating component, and a heat exchange portion thermally connected to the heat receiving portion, the heat exchange portion being located adjacent to the heat receiving portion and separate from the heat generating component;
• and
• an electric fan device for sending cooling air at least to the heat exchange portion of the heat sink, the electric fan device including a fan, a fan casing supporting the fan, and a heat sink support arranged adjacent to the fan casing,
• wherein the heat sink is pivotably supported by the heat sink support such that the heat receiving portion can move toward and away from the heat generating component, and the heat receiving portion is always urged by an elastic member toward the heat generating component.

An electronic apparatus comprising:

• a housing;
• a heat generating component housed in the housing;
• a heat sink housed in the housing, and including a heat receiving portion for receiving heat generated by the heat generating component, and a heat exchange portion thermally connected to the heat receiving portion, the heat exchange portion being located adjacent to the heat receiving portion and separate from the heat generating component, the heat sink being movable toward and away from the heat generating component, the heat sink being urged by an elastic member toward the heat generating component;
• and
• ventilation means housed in the housing for sending cooling air at least to the heat exchange portion of the heat sink.
