Application Cases

In modern electronic devices, thermal management of chips has always been a critical issue. With the continuous reduction in the size of electronic devices and the increase in power density, traditional cooling methods are no longer sufficient to meet the demands. Therefore, researchers have begun to explore new cooling solutions. Synthetic jet cooling technology, with its advantages of low energy consumption, no rotating parts, and simple structure, has the potential for research in electronic chip cooling. As a type of micro air pump, the piezoelectric synthetic jet pump utilizes the reciprocating motion of a piezoelectric actuator to drive the surrounding air for pumping. It not only improves cooling efficiency but also reduces energy consumption and size, adapting to the development trend of miniaturization and high performance of electronic devices. It has broad application prospects in active chip cooling.

Regarding experimental research on piezoelectric driving, the ATA-2000 series of voltage amplifiers from Antai Electronics has been widely used in this field. The ATA-2000 series can output an AC voltage of up to 1600 Vpp, capable of driving most piezoelectric devices on the market.

Experiment Name: Piezoelectric Jet Impingement Cooler Testing

Experiment Principle:Synthetic jet is a non-continuous jet technology that alternately blows and sucks surrounding fluid using a jet actuator. In a synthetic jet actuator, there is a driving element that can produce vibration (such as a piezoelectric vibrator), above which there is a cavity connected to the external fluid through an orifice. When the power amplifier drives the actuator to start working, the alternating blowing and sucking actions cause the fluid to form vortex pairs or vortex rings that move away from the orifice. Under specific conditions, these vortex pairs can avoid being re-sucked by the actuator. During the formation and downstream convection of the vortex pairs, the surrounding fluid is continuously entrained through induction, thereby controlling the flow field.

Experiment Process:A signal generator and power amplifier are used to provide the experimental prototype with the output signal. Below the experimental prototype is the cooling structure, which is heated by a DC power supply to the heat source within the cooling structure, and its input power can be controlled. A multi-channel temperature tester is used to monitor the temperature of the jet cooler.
