流体発振形冷却装置の開発 Development of Fluid Oscillating Cooling Device
This paper is concerned with the cooling unit which applies the flow mechanism of fluidics called the vortex chamber oscillation device. The water jet issuing from this cooling device impinges on the heated plate with swinging by itself. The flow aspect in the cooling device and the impinging patterns of the water jet have been studied by means of the high speed digital video camera and the image processing system. As a result, the oscillating period is estimated by the sequential frames from this camera. The large scale vortex is recognized from the vector diagram obtained by the PIV system. Explanation about the oscillating mechanism has been tried by using this large vortex. Moreover, the cooling process by this device is also visualized by using the temperature-sensitive liquid crystal film. The effects and the strong point of this cooling device have been discussed.
