THERMAL ANALYSIS AND DESIGN OF HYBRID MICROCHANNEL-MICROJET TEST PROBE

Abstract

The paper presents the numerical investigation of a microjet- microchannel cooling module. In which microjets of water are impinging into the microchannels and forming a liquid film on the impingement surface. Applied technology takes benefits from two very attractive heat removal techniques. When lminar jets are impinging on the surface have a very high kinetic energy at the stagnation point, also in microchannels boundary layer is very thin allowing to obtain very high heat fluxes. Applied technology of jet production can result with the jet hydraulic diameter from 200 to 500 μm, combined with microchannels 2mm wide and 2 mm high. Tests were conducted under steady state conditions, for water as test fluid.
