Abstract: An electronic apparatus comprises a first housing and a second housing. A junction between the first and second housings has three passages that connect an interior of the first housing and an interior of the second housing. A cable in which electric signals flow extends through one of the three passages. Two pipes are provided. The first pipe supplies liquid coolant heated in a heat-receiving portion. The second pipe supplies the liquid coolant cooled in a heat-radiating portion. The first and second pipes extend through the remaining two of the three passages, respectively.

Abstract: An electronic apparatus includes a housing, a heat-receiving portion thermally connected to a heat-generating component, a heat-radiating portion for radiating heat generated by the component, a pump for supplying liquid coolant to the heat-radiating portion, and a holding member secured to fixing portions and holding the pump in the housing. The pump has a plurality of peripheral walls. A plurality of fixing areas are provided outside the pump, each being located between two corners defined by an adjacent three of the peripheral walls. The fixing portions are aligned with the fixing areas.

Abstract: An electronic apparatus has a first housing, a second housing, a hinge mechanism and an interlocking mechanism. The hinge mechanism couples the first and second housings so that the housings are relatively rotated about first and second axes intersected with each other. An interlocking mechanism decreases a rotational resistance between the first and second housings about one of the two axes, while the first and second housing are relatively situated each other at a position of the rotation about the other axis.
