Design and optimization of staggered heat pipe heat sink with integral fins
摘要
Abstract
The simulation study on flow and heat transfer characteristics of the staggered heat pipe heat sink with integral fins was conducted based on the three-dimensional coordinate system. Four factors were considered;fin space (6mm,7mm and 8mm) ,fin thickness (0. 8mm,lmm and 1. 2mm) ,pipe row space (20mm,24mm and 28mm) and arrangement modes (4-3 staggered arrangement and 3-2 staggered arrangement). Three parameters were compared: film heat transfer coefficient .friction coefficient and thermal resistance. The results shown that:with the increasing of fin thickness,the friction coefficient decreased,heat transfer capability was enhanced and the thermal resistance ascended; with the increasing of fin space,the friction coefficient increased,heat transfer capability was enhanced and the thermal resistance ascended; while the 4-3 staggered arrangement to 3-2 staggered arrangement, heat transfer capability decreased, but the thermal resistance descended.关键词
