Abstract
A cooling unit comprises a heat receiving head provided in a main body, and a radiator provided in a display unit. The display unit is pivotably supported by the main body using a hinge shaft. The heat receiving head is thermally connected to a heat generating component incorporated in the main body. The heat receiving head is connected to the radiator via a circulation line for circulating cooling medium. The circulation line includes 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.
