摘要：

The　laminar　flow　and　heat　transfer　characteristics　of　fluid　were　numerically　investigated　through　uniform　and　double-side　heat　flux　3D　-IC(three-dimensional　integration　circuit)　with　interlayer　heat-removal　structure　for　heat　transfer　areas　of　1　cm2　and　volume　flow　ringing　from　36　mL/min　to　290　mL/min.　3D-IC　with　rectangle　micro-channels　and　staggered　micro-pin　fins　for　pitches　of　200　μm　and　structure　heights　of　200　μm　was　analyzed.　Results　show　that　inter-layer　liquid　cooling　of　3D-IC　with　staggered　micro-pin　fins　has　better　heat　exchange　effect　than　that　with　rectangle　micro-channels.　For　the　heat　flux　density　of　1.25　MW/m2,　the　average　temperature　and　maximum　temperature　of　the　heating　surface　are　only　318.31,　323.16　K,　decreased　12.31,　20.14　K　than　that　with　rectangle　micro-channels　at　the　volume　flow　of　290　mL/min,　corresponding　to　about　total　power　of　250W　and　volume　heat　source　of　8.3　kW/cm3.　©　2016,　Editorial　Department　of　Journal　of　Aerospace　Power.　All　right　reserved.
