摘要：

The　influence　of　electric　field　on　the　evaporation/boiling　heat　transfer　characteristic　for　an　evaporator　with　rectangular　micro-channels　was　experimentally　investigated.　R141b　was　used　as　the　working　fluid.　The　cylindrical　electrode　was　used　to　produce　electric　field.　The　experimental　result　indicates　that　heat　transfer　enhancement　is　strongly　dependent　on　the　electric　field　strength.　The　heat　transfer　enhancement　increase　with　the　increase　of　the　electric　field　strength.　Furthermore,　operating　pressure　has　a　strong　influence　on　the　evaporation/boiling　heat　transfer　enhancement　when　the　electric　field　strength　keeps　constant.　The　maximum　enhancement　of　heat　transfer　coefficient　is　1.28　times.　©　All　Rights　Reserved.
