Clean shed
The invention provides a clean shed, which has the characteristics of unidirectional laminar flow and uniform circulating air flow, can be suitable for ISO (International Standardization Organization) 3-4 levels and even higher cleanliness, and is beneficial to improving the yield and reducing the cost. The high-cleanliness clean shed according to the present invention is provided with: (A) a blow-out structure for achieving a high-cleanliness environment; (B) a double-wall structure for forming a uniform circulation path on the side wall of the greenhouse; (C) a rectifying structure for reducing turbulence, retention and dust raising of airflow generated by various devices; and (D) a local suction mechanism, which is designed by (E) numerical fluid dynamics (CFD) taking into account the actual conditions.
提供一种洁净棚，其形成成为单向层流及均匀循环的气流特性，能够适用于ISO 3级至4级甚至更高清洁度，有利于提高产率、降低成本。本发明的高清洁度洁净棚具备：(A)用于实现高清洁度环境的吹出结构；(B)用于使棚侧壁成为均匀的循环路径的双壁结构；(C)用于减少由各种装置产生的气流的紊乱、滞留及扬尘的整流结构；以及(D)局部抽吸机构，这些通过考虑了实际条件的(E)数值流体力学(CFD)设计。
