摘要：

The　influence　of　electric　field　on　the　evaporation/boiling　heat　transfer　characteristics　for　an　evaporator　with　rectangular　micro-channels　was　experimentally　investigated.　R141b　was　used　as　the　working　fluid.　The　operating　pressure　was　1.01×105　Pa.　Experimental　results　show　that　electric　field　has　an　significant　effect　on　the　thermal　performance　of　the　evaporator.　The　heat　transfer　enhancement　effects　increase　with　the　increase　of　the　electric　field.　Under　applied　electric　field　intensity,　the　heat　transfer　efficient　enhancement　factor　can　reach　as　high　as　0.7.　The　change　of　heat　transfer　efficient　enhancement　factor　is　leveling　off　under　higher　heat　flux.
