Uniform　flow　distribution　is　critical　to　obtain　high　thermal　performance　in　many　heat　and　mass　transfer　devices.　It　especially　plays　an　important　role　in　a　compact　heat　exchanger.　In　this　paper,　a　two-phase　flow　distributor　is　proposed　for　the　evaporator　unit　of　the　plate-fin　heat　exchanger　to　alleviate　the　phase　maldistribution　in　the　multiphase　flow.　Air　and　water　mixture　was　adopted　as　two-phase　medium　and　distributions　into　ten　parallel　channels　were　measured　in　detail.　The　results　show　that　the　proposed　distributor　can　improve　the　two-phase　flow　distribution　of　the　plate-fin　heat　exchanger.　(C)　2012　Elsevier　Ltd.　All　rights　reserved.
