    • A falling film evaporator is provided for use in a two-phase refrigeration system or process system. The evaporator (80, 280) includes a shell (100) having an upper portion (102), a lower portion (104), and a tube bundle (106) having tubes extending substantially horizontally in the shell (100). A hood (112) is disposed over the tube bundle (106), the hood (112) having an upper end (114) adjacent the upper portion (102) above the tube bundle (106), the upper end (114) having opposed substantially parallel walls (116) extending toward the lower portion (104), the walls terminating at an open end (118) opposite the upper end (114). Once liquid refrigerant (120) or liquid refrigerant (120) and vapor refrigerant is deposited onto the tube bundle (106), the substantially parallel walls (116) of the hood (112) substantially prevent cross flow of refrigerant vapor or liquid and vapor between the tubes of the tube bundle (106).
    • 提供降膜蒸发器用于两相制冷系统或过程系统。 蒸发器(80,280)包括具有上部(102),下部(104)和管束(106)的壳体(100),管束(106)具有在壳体(100)中基本水平延伸的管子。 罩(112)设置在管束(106)上方,罩(112)具有与管束(106)上方的上部(102)相邻的上端(114),上端(114)具有相对的 基本平行的壁(116)朝向下部(104)延伸,所述壁终止于与上端(114)相对的开放端(118)。 一旦液体制冷剂(120)或液体制冷剂(120)和蒸气制冷剂沉积到管束(106)上,则罩(112)的基本上平行的壁(116)基本上防止制冷剂蒸气或液体和蒸汽之间的交叉流动 管束(106)的管。
