In　this　paper,　it　was　investigated　experimentally　that　the　effect　of　different　kinds　of　working　fluid　on　the　thermal　performance　of　evaporator　with　capillary　wick　consisted　by　multilayered　sintered　copper　mesh　under　different　electric　field　strengths　at　the　operating　pressure　of　1.01　x　10(5)　Pa　R141b　and　R123　were　used　as　the　working　fluids.　The　electric　field　strength　in　this　study　was　in　the　range　of　0kV/m-1600　kV/m,　respectively.　The　experimental　results　showed　that　the　applied　electric　field　strength　has　significant　effect　on　heat　transfer　characteristic.　The　heat　transfer　enhancement　effects　increased　with　the　increase　of　the　electric　field.　Under　the　applied　electric　field　strength,　the　maximum　heat　transfer　enhancement　factors　could　reach　as　high　as　1.5　and　1.32　for　the　two　kinds　of　working　fluids　in　the　experiment.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
