FAST LOCAL TRANSIENT SOLUTION OF MULTI-LAYERED MICRO-CHANNEL HEAT SINK

摘要：

Thermal analyses of one-, two-and three-layered micro-channels have been carried out. Finite element method (FEM) and asymptotic waveform evaluation (AWE) are used to obtain the transient response equation of one node. When the transient response graph is smooth and monotonic towards steady state temperature, AWE approximates this graph well even at small number of moments. However, if the transient response graph shows irregular pattern towards steady state temperature, higher number of moments are required to obtain a good approximation. Results indicate that three-layered micro-channel gives significant reduction in thermal resistance.
