Micro-scale droplet was effectively applied to the CPU cooling. The PZT actuated porous membrane device which generating the micro-scale droplet with high latent heat of phase changes between liquid and vapor of water to achieve high heat transfer performance, it could remove heat from the CPU surface effectively for over 100 Watts as cooling system. And the device operating below the pressure of ambient environment prevents leakage as system fail. In order to design an efficient cooling device, it was important to study the dimensional effects of PZT actuator on the orifice plate vibration mode to pinch off droplet. The frequency and the applied voltage used to energize the PZT transducer were also important parameters that should be properly controlled in order to achieve the optimal liquid breakup conditions. The maximum flow rate approach 27 ml/min when operated at 50 kHz with 2.75 W, It also reveals the low noise and power consumption in the CPU cooling system.
