چکیده

Parallel micro/mini-channel heat sinks are widely used for the efficient cooling of electronic devices to avoid functional damage and lifetime shortening due overheating. This study addresses optimization fluid flow distribution in parallel mini-channel subjected a non-uniform multiple-peak flux eliminate temperature hotspots. A 3D sink comprising 16 straight mini-channels is as model study, each having dimension 1 mm width, 2 height 34 length. In particular, an original algorithm developed adjust inlets these according on heating base surface. The thereby tailored, leading reduced peak effectiveness robustness tested discussed. Results obtained show that maximum can be by 10 K 7 two-peak five-peak cases, respectively, using proposed method. configuration with optimized channel could always provide smaller thermal resistance than equal inlet under different average or total mass flow-rate conditions. At same pressure drop, tailoring more effective reducing simply increasing rate liquid. method also generalized management technology cooling.
