Abstract: According to one embodiment, an electronic apparatus comprising a housing including a suction port and an exhaust port, a heat generating element accommodated in the housing, a heat receiving portion accommodated in the housing, and thermally connected to the heat generating element, a fan disposed in the vicinity of the suction port within the housing, and which sucks a cooling air through the suction port, and a heat radiating portion accommodated in the housing, and configured to radiate heat of the heat generating element, wherein the heat radiating portion is disposed between the suction port and the fan, and the heat receiving portion is arranged in a discharge region of the cooling air extending from the fan to the exhaust port.

Abstract: According to one embodiment, a cooling device includes: a first heat receiving portion that is configured to be thermally connected to a first heating element; a second heat receiving portion that is configured to be thermally connected to a second heating element having a greater heating value than the first heating element, the second heat receiving portion having a pump that pressurizes and feeds a liquid refrigerant; a heat radiation portion that radiates the heat received by the first and second heating elements; and a circulation passage that circulates a liquid refrigerant around the first heat receiving portion, the second heat receiving portion, and the heat radiation portion, wherein the second heat receiving portion is located at a position upstream with respect to the first heat receiving portion in a flow direction of the liquid refrigerant and downstream with respect to the heat radiation portion in the flow direction.

Abstract: A computer can be provided with small-sized, light-weight, and furthermore cableless features by efficiently positioning the components of the computer and display device. The computer system includes a wearable computer and a wearable display device provided independently of this computer. A display controller is installed in the display device, not in the computer. The computer controls the display controller by radio or wire.
