| 摘 要： | 在计算机芯片冷却方式中,喷液冷却比风冷和微槽道液冷效率高,冷却效果好。普通机械泵及压电薄膜泵无法满足微孔尺度的微小化带来的高驱动压力问题。利用叠堆式压电陶瓷作为致动器,设计了一种基于叠堆式压电陶瓷驱动流体进行喷射冷却的冷却器,进行了同一驱动参数下微孔数量与尺度配比冷却实验研究,试验结果表明:相同面积的微喷板上采用多数量小孔径结构的微喷冷却器具有较佳的冷却效果。

| Abstract: | In the patterns of cooling computer chip,liquid injection cooling is higher efficiency than air cooling and micro groove cooling heat sink.Mechanical pump and piezoelectric pump are unable to provide driving pressure caused by the micro jet size miniaturization.By use of piezoelectric stack actuator,the micro-injection cooler based on piezoelectric stack actuator driving cooling fluid was designed.Experiments under various micropore amounts and size were completed with same driving Condition.Test results sh... |
