摘要：

The　thermal　performance　of　pin-fin　heat　sinks　with　confined　and　submerged　liquid　water　jet　array　impingement　was　investigated　experimentally.　The　experimental　results　indicate　that:　the　performance　of　heat　sinks　is　closely　related　to　the　height　of　the　pin-fin,　but　not　the　higher　the　better;　Nusselt　number　is　represented　by　pyramidal　distribution　in　0.625≤W/G≤1.000;　for　the　confined　and　submerged　jet　arrays　a　strong　dependence　on　both　jet-to-target　and　jet-to-jet　spacing　can　be　observed,　and　Nusselt　number　falls　continuously　between　2.5≤H/d≤10.0;　an　increment　in　jet-to-jet　spacing　between　3.00~4.50　can　be　found　to　decrease　Nusselt　number　when　Re
