Cooling unit for cooling heat generating component and electronic apparatus equipped with the cooling unit

An electronic apparatus comprising:

• a main body having a heat generating component;
• a display unit pivotably supported by the main body using a hinge shaft;
• heat receiving means provided in the main body and thermally connected to the heat generating component;
• heat exchange means provided in the display unit;
• and
• circulation means for circulating cooling medium between the heat receiving means and the heat exchange means, the circulation means including a bending-force-absorbing section having a shape that is deformable to twist about an axis of the hinge shaft when the display unit is pivoted, the bending-force-absorbing section being located along an extended line of the axis of the hinge shaft.
