According to one embodiment of the invention, an electronic apparatus comprises a main unit, a display unit and a support unit. The main unit contains a heat-generating component and a heat-receiving portion. The heat-receiving portion is thermally connected to the heat-generating component. The support unit supports the display unit on the main unit and contains a heat-radiating portion that radiates the heat of the heat-generating component. The heat of the heat-generating component is transmitted to a heat-transferring medium and transferred to the heat-radiating portion through the heat-transferring medium.

An electronic apparatus includes a housing provided with first and second connectors, a first fixing member receiving element positioned on the side of the first connector opposite to the second connector side, a second fixing member receiving element positioned on the side of the second connector opposite to the first connector side, and a third fixing member receiving element positioned between the first connector and the second connector. First and second plugs are removably connected to the first and second connectors. The first fixing member receiving element fixes one fixing member of the first plug. The second fixing member receiving element fixes one fixing member of the second plug. The third fixing member receiving element fixes either the other fixing member of the first plug or the other fixing member of the second plug.

A cooling unit including a fan, a plurality of heat-radiating fins and a tube. Liquid coolant that has absorbed heat from a heat-radiating component is made to circulate in the tube. The fan has an impeller. The draws cooling air at its center part and expels the cooling air at its periphery. The heat-radiating fins oppose the periphery of the impeller. The tube is thermally connected to the heat-radiating fins.

An electronic apparatus has a hinge mechanism, which connects a main unit and a display unit. A first shaft of the hinge mechanism connects the display unit to the main unit such that the display unit is rotatable between a closed position where the display unit overlies the main unit and an open position where the display unit is raised up from the main unit. A second shaft of the hinge mechanism is perpendicular to the first shaft and connects the display unit to the main unit so as to be rotatable in a circumferential direction of the second shaft. The main unit has a braking mechanism, which generates braking force that limits rotation of the display unit between the closed position and the open position. The display unit has an engagement member, which is removaly engaged with the braking mechanism.

Electronic apparatus having display unit rotatably connected to main unit

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 to each other at a position of the rotation about the other axis.

An electronic apparatus includes a first housing and a second housing. The first housing incorporates a pump. The second housing incorporates a heat-radiating portion. The pump has a heat-receiving portion. A circulation path for circulating liquid coolant connects the pump and the heat-radiating portion. The circulation path has two pipes. The first pipe connects the pump to the coolant inlet port of the heat-radiating portion. The second pipe connects the pump to the coolant outlet port of the heat-radiating portion. The first and second pipes extend from two adjacent points on the pump, toward a midpoint between the coolant inlet port and coolant outlet port.

An electronic apparatus comprises a heat-generating component, a main unit having a heat-receiving portion thermally connected to the heat-generating component, and a display unit supported by the main unit. The display unit incorporates a heat-radiating portion which radiates the heat of the heat-generating component. A circulating path connects the heat-receiving portion and the heat-radiating portion and circulates liquid coolant. The heat-radiating portion includes a first radiator and a second radiator. The radiators are connected in series in a direction in which the liquid coolant flows. The second radiator is located at the downstream of the liquid coolant, and is exposed outside the display unit.
