The　maldistribution　of　two-phase　flow　is　one　of　the　major　factors　that　deteriorate　the　heat　transfer　performance　of　plate-fin　heat　exchanger.　The　set-up　of　flow　distributor　at　the　heat　exchanger　inlet　is　one　widely　adopted　engineering　method　to　improve　the　flow　distribution.　In　this　paper　the　flow　distribution　performance　of　one　type　of　distributor　is　experimentally　tested　by　using　air-water　mixture.　The　test　results　show　that　the　flow　distributor　studied　can　improve　the　two-phase　flow　distribution　uniformity　in　plate-fin　heat　exchanger.　©　All　Rights　Reserved.
