摘要： A separator has a concavo-convex structure formed in mutually reversed shapes on two opposite sides thereof to define flow paths of different fluids on the respective two sides. The concavo-convex structure includes multiple first projections formed and protruded on one side of the two opposite sides and arranged at intervals having a preset regularity. The concavo-convex structure also includes multiple second projections formed and protruded on the other side of the two opposite sides in a specific area corresponding to an area for formation of the multiple first projections on the one side and arranged at intervals having a preset regularity. The concavo-convex structure further includes reinforcing elements protruded on the one side. Each of the reinforcing elements is formed as a convex in a specific shape of connecting multiple positions where the first projections are expected to be formed according to the preset regularity, while avoiding positions corresponding to the second projections formed on the other side. This arrangement effectively prevents a potential trouble caused by deformation of the separator due to a pressure difference between the flow pressures of the respective fluids flowing on the respective sides of the separator.
摘要翻译：分离器具有在其两个相对侧上以相互反转的形状形成的凹凸结构，以限定相应两侧上不同流体的流动路径。凹凸结构包括在两个相对侧的一侧上形成和突出的多个第一突起并以预定的规则间隔布置。凹凸结构还包括在对应于一侧上形成多个第一突起的区域的特定区域中在两个相对侧的另一侧上形成和突出的多个第二突起，并且以预定的规则间隔布置。凹凸结构还包括在一侧突出的增强元件。每个加强元件形成为具有预定规则性地预期形成第一突起的多个位置的特定形状的凸起，同时避免与形成在另一侧上的第二突起相对应的位置。这种布置有效地防止了由于在分离器的各个侧面上流动的各个流体的流动压力之间的压力差引起的分离器变形引起的潜在故障。
