摘要
A micro-fluidic oscillator comprises a main body and a cover body for covering the main body. An oscillation chamber is disposed on the main body to provide an oscillation space for fluid. A sudden-expansion micro-nozzle is connected with one end of the oscillation chamber, and an outlet passage is connected with the other end of the oscillation chamber. Two fluid-separating bodies are located at the connection positions of the outlet passage and the oscillation chamber, respectively. Two feedback channels are located outside two attachment walls. The sudden-expansion micro-nozzle is used to break the viscous shear stress between fluid and the walls and to generate unstable flow and oscillation. Moreover, the two feedback channels have different lengths, inside diameters and alternate outlet positions to further enhance the oscillation of fluid.
