    • A refrigeration system includes a phase separator disposed in flow communication with a pulse width modulated solenoid valve. A thermistor is disposed in the phase separator and is submerged in either refrigerant liquid or refrigerant vapor during operation, with the electrical resistance thereof correspondingly changing. In an exemplary embodiment, a second thermistor is used in conjunction with the first thermistor and is disposed in the vapor inside the phase separator to provide a reference. By comparing voltage developed across the two thermistors during operation it may be determined whether one or both of the thermistors are submersed in the vapor. The duty cycle of the valve may therefore be increased when one of the thermistors is submerged in the liquid, and decreased when both thermistors are submersed in the vapor.
    • 制冷系统包括与脉宽调制电磁阀流动连通的相分离器。 热敏电阻设置在相分离器中,并且在操作期间浸没在制冷剂液体或制冷剂蒸汽中,其电阻相应变化。 在示例性实施例中,第二热敏电阻与第一热敏电阻结合使用,并且设置在相分离器内部的蒸气中以提供参考。 通过比较在操作期间跨两个热敏电阻产生的电压,可以确定热敏电阻中的一个或两个是否浸没在蒸汽中。 因此,当热敏电阻中的一个浸没在液体中时,阀的占空比可以增加,并且当两个热敏电阻浸没在蒸汽中时,阀的占空比减小。

    • A device for improving heat dissipation inside an ultrasound probe and reducing heat build-up near the transducer face. Heat conductors are placed around the periphery of the transducer package, but within the probe housing, so that heat can be drawn away from the transducer face and toward the rear/interior of the probe. The heat conductors act as conduits for draining away heat which builds up in the thermal potting material during pulsation of the piezoelectric transducer elements. The heat conductors are formed from metal foil having a heat conductivity greater than the heat conductivity of the thermal potting material which fills the spaces inside the probe housing and surrounds the transducer package. The preferred metal foil is aluminum.
