Effects of heat transfer characteristics on wave mini-channel heat sink with secondary passage and analysis of field synergy effect

  • Received Date: 2017-03-09
  • For the enhancement of integration level and calorific value of micro-electro-mechanical and microelectronics components, wave mini-channel heat sinks (WMS) which could enhance secondary flow of the fluid in mini-channel were designed.On the basis of this structure, the secondary flow passages were added to further improve its heat transfer characteristics. CFD software was used to simulate WMS with and without secondary passage and to investigate the effect on heat transfer in laminar flow state. The results showed that, as far as this study was concerned, when the Re of inlet fluid was less than 1008, the heat transfer characteristic of WMS with secondary passages was better than the one of WMS; secondary passages didn’t improve the temperature uniformity of mini-channel heat sink back surface. Then, through the analysis of the field synergy theory, it was found that secondary passages improved the synergy degree between velocity field and temperature field of wave mini-channel at the low Re, the heat transfer ability of WMS was improved.
