    摘要： A refrigeration system allows the refrigerant to circulate through a closed circulation channel. A dry evaporator is incorporated in the circulation channel. The dry evaporator is designed to keep a quality smaller than 1.0 in evaporating the refrigerant. The quantity of heat transfer per unit area, namely, a heat transfer coefficient depends on the quality. The heat transfer coefficient remarkably drops when the quality of the refrigerant exceeds a predetermined threshold level before the quality actually reaches 1.0. The quality of the refrigerant kept below the predetermined threshold level during vaporization of the refrigetant in the dry evaporator allows a reliable establishment of a higher performance of cooling. On the other hand, if a refrigerant completely evaporates in a dry evaporator in a conventional manner, the heat transfer coefficient of the refrigerant remarkably drops after the quality of the refrigerant exceeds the predetermined threshold level. Accordingly, the conventional dry evaporator is forced to absorb heat at a lower heat transfer coefficient, as compared with the present dry evaporator.

    摘要： A cooling system used with a printed circuit board has at least a solid circuit component thereon. The cooling system comprises a cooling header and cooling modules connected to the cooling header. Each of the cooling modules engage to each of the components. The cooling module has a heat transfer plate connected to one end of a bellows which is connected to the cooling header at the other end. A layer of thermally conductive compound, such as a layer of thermal grease, is interposed between the heat transfer plate and the corresponding circuit component. The thermally conductive layer is initially pressed with a pressure higher than a critical pressure, and thereafter, the pressure is reduced to a working pressure exerted on the circuit component provided by the resilient force of the bellows and the hydraulic pressure of the coolant. The critical pressure is predetermined experimentally or practically. As the result, the thermal contact resistance between the heat transfer plate and the circuit component is favorably reduced and stabilized.

    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.
