Topology Optimization Design of Micro-Channel Heat Sink by Considering the Coupling of Fluid-Solid and Heat Transfer

To investigate the effect of target weight coefficient on structure design micro-channel heat sink, an innovative method for topology optimization structures with different bifurcation angles is adopted. In this study, improved interpolation function, density filtering, and hyperbolic tangent projection methods are adopted to obtain a clear topological sink. The transfer sink under compared. At same time, influence two objective functions, transfer, flow energy consumption, analyzed in sinks. results show that when angle 135°, both average outlet temperature maximum value, best. With increase weighting coefficient, distribution solid sources main channel increases, refinement branch channels also increases. On other hand, although best, corresponding consumption larger.
