Abstract：

In　this　chapter,　a　new　microchannel　heat　sink　with　staggered　structure　was　designed　based　on　thermal　boundary　layer　technology　for　enhancing　heat　transfer　performance　and　reducing　flow　resistance.　Comparative　experiments　were　carried　out　between　a　test　section　having　the　new　staggered　structure　microchannel　and　a　conventional　straight　microchannel　keeping　the　values　of　three　control　parameters,　inlet　temperature,　heating　power,　and　flow　rate,　very　close.　The　results　indicated　that　there　was　an　obvious　difference　between　the　friction　resistance　factor　from　experimental　data　and　calculated　values　from　theoretical　formula.　The　staggered　structure　increased　the　partial　friction　resistance　to　a　certain　extent,　but　the　advantage　for　heat　transfer　was　more　evident.　The　temperature　distribution　of　the　wall　was　more　uniform　along　the　flow　direction.　©　2012　Nova　Science　Publishers,　Inc.
