Abstract: The invention relates to a system for cooling electrical and electronic components and devices placed in a housing. The invention is particularly intended for outdoor cabinets and housings of the telecommunications technology. In order to create a cooling system in which an inexpensive filter is used and positioned in such a way as to ensure an extremely good sealing action, a filter trough is placed in a housing wall or door, in which the filter is received so as to be detachable and replaceable from the outside and is sealed against the filter trough on its air outlet side with the aid of a circumferential seal.

Abstract: The invention is directed to a fastener for multiple locking of doors or wall portions in housings or cabinets, particularly for outdoor use, by means of a lockable actuation member such as a handle lever, comprising a drive toothed wheel which is connected to the actuation member supported in the door so as to be rigid against rotation and which engages with a lock rod which is supported in the door so as to be displaceable axially and which has teeth on at least one side, and with lock elements which are held in the door so as to be rotatable or swivelable and which are coupled with the lock rod. According to the invention, for each lock element, a driven toothed wheel which is connected to the lock elements so as to be rigid against rotation and which engages with the teeth of the lock rod is held on the door in a rotatable manner in order to couple the lock rod with the lock elements.

Abstract: The invention relates to a sealing arrangement for an enclosure or equipment cabinet and to an attachable air conditioning device. In order to ensure a watertight, linear sealing of the air distribution spaces with the necessary protection level, sealing frames and seals cooperating therewith and appropriately an additional cover are provided between the air conditioning device and the covering part.
