Electronic cooling using synthetic impinging jet

The efficiency and mechanisms of cooling a constant heat flux surface by impinging synthetic jets were investigated experimentally and compared to cooling with continuous jets. Effects of jet formation frequency and Reynolds number at different nozzle-to-surface distances (H / d) were investigated. High formation frequency (f = 1200 Hz) synthetic jets were found to remove heat better than low frequency (f = 420 Hz) jets for small H / d, while low frequency jets are more effective at larger H / d. Moreover, synthetic jets are about three times more effective in cooling than continuous jets at the same Reynolds number. Using PIV, it was shown that the higher formation frequency jets are associated with breakdown and merging of vortices before they impinge on the surface. For the lower frequency jets, the wavelength between coherent structures is larger such that vortex rings impinge on the surface separately.

The Anomatic series of high-quality deep drawn Aluminum Canisters is designed to be compatible with your chosen valves, Actuators and drug formulations.  Our deep drawing process ensures a consistent side wall thickness using high strength aluminum which is far superior to other forming methods.  The aluminum is work hardened during the deep draw process and the surface mechanically polished providing a smooth, hard internal finish suitable for use with both CFC and HFA propellants. 

Aluminum anodization is an electrochemical process that enhances the strength, durability, and appearance of aluminum.  When aluminum is oxidized, super-strong oxide (anodic) layers [grow" on the surface of the metal. These new layers are highly resistant to wear and corrosion.

The exacting part to part consistency achieved with our unique anodizing system cannot be obtained with conventional hoist line systems.  Conventional anodizing systems present parts with varied coating thicknesses and voids formed due to air pocketing.
