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 drive circuit of a piezoelectric pump that is both light and compact, that can drive a piezoelectric pump with a low level of undesired noise, and that can further realize with low power consumption a coolant device capable of reliable operation at the time of activation. 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 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.
