交织网状小通道热沉的传热特性
Heat transfer characteristics of interwoven network minichannel heat sinks
摘要
Abstract
In order to cope with the increasing heat dissipation demand of micro-electronic devices,this paper optimizes the flow channel layout of the minichannel heat sink,avoids some flow dead zones,reduces unnecessary flow branches,and obtains an interwoven block coupled honeycomb minichannel with better heat transfer performance.The flow and heat transfer characteristics of nanofluids in minichannels were studied by numerical simulation.The results indicated that the average temperature of the improved heat sink wall is reduced by 2.16 K.Compared to water,the Nusselt number of the nanofluids with the mass fraction of 0.5%as the cooling medium is increased by 13.1%,the thermal resistance is reduced by 12.4%,and the comprehensive evaluation coefficient PEC of the whole minichannel under the best working condition reaches 1.211.关键词
