摘要:
A fan cooling unit (10) for cooling electronic components, such as for an air-cooled telecommunications base station, comprises a protective covering for at least the air inlet opening (11) of a casing (8) in which the electronic components are housed. The protective covering (1) has a frame (2) into which a composite filter media (3) is mounted so as to create an air-tight fit. The composite filter media (3) comprises a membrane filtration layer (20) with a porous polymeric membrane, such as expanded polytetrafluoroethylene (ePTFE), and at least one depth filtration layer (18) disposed on an upstream side of the membrane filtration layer (20). The depth filtration media layer comprises fibers having an electrostatic charge. The ePTFE membrane is preferably made from a blend of a PTFE homopolymer and a modified PTFE polymer.
摘要(中):
用于冷却诸如用于风冷电信基站的电子部件的风扇冷却单元(10)包括至少用于容纳电子部件的壳体(8)的进气口(11)的保护罩 。 保护罩(1)具有框架(2),复合过滤介质(3)安装在该框架(2)中以形成气密配合。 复合过滤介质(3)包括具有多孔聚合物膜(例如膨胀的聚四氟乙烯(ePTFE))的膜过滤层(20)和设置在膜过滤层的上游侧的至少一个深度过滤层(18) 20)。 深度过滤介质层包含具有静电电荷的纤维。 ePTFE膜优选由PTFE均聚物和改性PTFE聚合物的共混物制成。
