摘要
Abstract
This paper introduces the working environment of outdoor sealed chassis.The sealed chassis should solve seeper for"congealing dew" and "respiratory effect". After comparing different protective designs,the solution of adopting waterproof ventilated valve in outdoor sealed chassis is put forward. Installation and selection requirements of waterproof ventilated valve are discussed. The waterproof ventilated valve can continuously ventilate,balance the pressure difference inside and outside the chassis quickly, avoid the negative influence brought by the high pressure difference,effectively solve the problem of water accumulation in the out?door sealed chassis,and improve the working environment of the electronic components in the sealed chassis,Thus,the reliability of the equipment is improved and the service life of the equipment is prolonged.关键词
