摘要： A cooling device for a portable electronic comprises a radiation plate and a fin for radiating the heat from the CPU. When the plug of an external power. supply is attached to the body of the portable electronic, the CPU may operate at a high clock frequency. The cooling device achieves a high cooling performance by operating a ventilation fan directed to the fin, for example. When the plug is removed from the body of the portable electronic, the CPU may operate at a low clock frequency. Power consumption can be reduced, so that the electric power stored in the built-in battery can be saved. The duration time of the operation can be extended. Calorific power generated at the CPU can also be reduced, so that the cooling device is adapted to suppress the rise in the temperature of the CPU without operation of the ventilation fan.

摘要： An intake opening is defined in a printed circuit board inside a fan cover mounted on the printed circuit board. The intake opening has a particular extent inside the fan cover. This intake opening contributes to improvement in the cooling efficiency of a fan as compared with a conventional intake opening. Moreover, the intake opening allows a sufficient space to remain on the front and back surfaces of the printed circuit board inside the fan cover. Electronic components and/or wiring patterns may be disposed in the space. This contributes to disposition of electronic components and/or wiring patterns at a higher density on the printed circuit board.

摘要： A heat receiver includes a casing defining a flow passage on a thermal conductive plate. The thermal conductive plate is received on an electronic component. The thermal conductive plate serves to transfer heat to coolant in the flow passage. At least two inflow nozzles extend into the casing to have discharge openings opposed to the upstream end of the flow passage. The coolant flows into the flow passage through the inflow nozzles. At least two streams of the coolant are thus generated in the flow passage. The streams widely expand or spread in the flow passage. The coolant flows through the flow passage without stagnating. The coolant can thus absorb the heat of the thermal conductive plate in an efficient manner. This results in an efficient heat absorption of the heat receiver.

摘要： A liquid cooling unit includes components such as first and second heat receivers, a heat exchanger, a tank and a pump in an electronic apparatus. The electronic apparatus includes a first enclosure and a second enclosure coupled to the second enclosure for relative movement. The liquid cooling unit is enclosed in the first enclosure. No component of the liquid cooling unit is enclosed in the second enclosure. The liquid cooling unit is thus incorporated in the first enclosure in a facilitated manner. This results in a reduced production cost. The liquid cooling unit can also be removed from the first enclosure in a facilitated manner.

摘要： An electronic component generates heat in an electronic apparatus. The heat of the electronic component is transferred to a thermal conductive plate of a heat receiver in a liquid cooling unit. The heat is transferred to coolant from the thermal conductive plate. The temperature of the coolant rises. The heat exchanger absorbs heat of the coolant. The coolant gets cooled. The heat of the electronic component is also transferred to the printed wiring board. The heat spreads over the printed wiring board through a wiring pattern in the printed wiring board. Since the tank or/and pump is placed at a position outside the printed wiring board, the heat cannot be transferred to the tank or/and the pump. This results in prevention of rise in the temperature of the coolant in the tank or/and the pump. The efficiency of heat radiation can thus be enhanced.

摘要： An electronic apparatus includes an enclosure enclosing a liquid cooling unit. The liquid cooling unit includes a heat receiver received on an electronic component. Heat of the electronic component is transferred to the heat receiver. The heat of the heat receiver is transferred to the coolant flowing through the flow passage of the heat receiver. The electronic component gets cooled. The coolant flows into a tank in the liquid cooling unit. The tank stores the coolant and air. The air inlet is formed in the enclosure. Fresh air is introduced into the enclosure through the air inlet. Since the tank is opposed to the air inlet, the tank is exposed to the fresh air. The heat of the coolant in the tank is thus radiated into the air. The coolant gets cooled in an efficient manner. The efficiency of heat radiation is enhanced in this manner.

摘要： A heat exchanger allows establishment of first and second flat spaces, namely parallel flat spaces along a reference. The heat exchanger is inserted in a closed circulating loop for coolant. The first and second flat spaces have a cross-section larger than that of a cylindrical duct of the closed circulating loop. These flat spaces serve as a flow passage for the coolant. An increased cross-section enables a reduction in the flow speed of the coolant. The coolant is allowed to slowly flow through the first and second flat spaces. The coolant thus contacts with the first and second plates and the third and fourth plates for a longer time. The heat of the coolant is sufficiently transferred to the first and second plates and the third and fourth plates. The efficiency of heat radiation is enhanced.
