摘要： A liquid-cooled heat radiator 1 includes a heat radiation base 2 having a cooling-liquid channel 5, and an expansion tank 7 provided on the heat radiation base 2. The expansion tank 7 has a tank body 26 having an expanded portion 27, which expands upward and opens downward, and a bottom plate 28 joined to the lower end of the tank body 26 to thereby close a bottom opening of the expanded portion 27. A through-hole 29 is formed in the top wall of the expanded portion 27 of the tank body 26 and serves as a communication section for establishing communication between the interior and the exterior of the cooling-liquid channel 5. A hydrogen-permeable member 31 is fixedly fitted into the through-hole 29 so as to stop the through-hole 29. The hydrogen-permeable member 31 satisfies the relation B≧50 A, where A and B are water-vapor permeability and hydrogen permeability, respectively, of the hydrogen-permeable member 31. The hydrogen-permeable member 31 is formed from a single material selected from the group consisting of ethylene-propylene rubber, butyl rubber, fluorine-containing rubber, nitrile-butadiene rubber, and silicone rubber. The liquid-cooled heat radiator 1 can be free from an increase in pressure in the cooling-liquid channel 5.

摘要： A piezoelectric element of the piezoelectric pump is driven by the output signal of an amplifier that takes as input a signal that is generated by a sine wave oscillator of the same frequency that drives the piezoelectric element. The amplifier is driven by a high voltage obtained by conversion from a low-voltage power supply by a voltage-boosting converter, whereby the piezoelectric element is driven by a low-frequency sine wave of high voltage. The frequency of the sine wave oscillation is further adjusted by a signal from a first control circuit at the time of activation. In addition, the amplitude of the sine wave oscillation is adjusted by the output signal of a second control circuit that takes as input a signal from temperature sensor for sensing the temperature of the heat-generating body.

摘要： A cooling device includes a cooling panel wherein a passage is formed by bonding together a bottom heat radiation plate having a groove formed therein and a top heat radiation plate, and a circulation pump circulating refrigerant within the passage. The top heat radiation plate is provided with an outlet port through which the refrigerant flows out from the passage to the circulation pump and an inlet port through which the refrigerant flows in from the circulation pump to the passage. The circulation pump is fixed onto the top heat radiation plate of the cooling panel so that the suction port and discharge port are aligned with the outlet port and inlet port, respectively.
