2014年12月1日 · The flow characteristics of a dual piezoelectric cooling jet (DCJ) were investigated by numerical analysis. The results of various turbulence models were compared with the results of previous experimental reports to develop the reference numerical model.

2014年12月1日 · An alternative to conventional forced convection approaches is the dual cooling synthetic jet (DCJ) [2]. The DCJ is based on two piezoelectric disks that draw external air into a cavity between them during an expansion stroke, and expel that air at high velocity during a subsequent compression stroke (Fig. 1(a)).

Abstract: This work presents results obtained on the characterization of hydrodynamics and thermal transfer coupling of a Dual piezoelectric Cool Jet (DCJ). The convective heat transfer coefficient was evaluated through experimental tests and numerical studies.

2024年5月1日 · The impact of the dual piezoelectric cooling jet (DCJ) device on the heat transfer coefficient was examined by measuring the power and temperature along a heating plate. Remarkably, they observed a substantial 50 % increase in the heat transfer coefficient.

175 Hz, corresponding to resonance frequency of piezoelectric material, seems to be the best frequency to obtain the highest magnitude of velocity. In the vertical direction, the produced jet width...

2012年12月14日 · 这种散热器名为DCJ（Dual Piezoelectric Cooling Jets，双压电冷却喷射），可以理解为一个向电子设备喷射高速空气的微流风箱，DCJ发出的 湍动空气相比常规的对流空气10倍提升了热交换速率。

In this study the flow performance of a novel thin form-factor cooling solution, the advanced dual piezoelectric cooling jet (DCJ), is evaluated. A DCJ is a micro-fluidic device that disturbs the boundary layer over a hot component and hence increases heat transfer.

2013年9月19日 · Dubbed Dual Piezoelectric Cooling Jets, or DCJ, the system works as a system of of bellows providing high-velocity jets of air to cool components down far more efficiently than just convection alone. So far, so like the high-tech wizardry known as a 'fan' - but DCJ coolers are half the thickness and use half the energy while operating in almost ...

2014年12月1日 · Dual Cool Jet (DCJ) is a variant of variable orifice synthetic jet(VO-SJ) consisting of piezo actuated metal disks that are mechanically configured to form a...
