Embodiment Construction

[0029] exist figure 1 and 2 In the case of the shown system for cooling electrical and electronic components, modules and devices (not shown), the fan 21 is located in the upper region of the rear wall 25 .

[0030] To remove dissipated heat from the modules and devices in the interior 26 of the housing 2 , the fan 21 draws in fresh air 5 via the air intake 15 and filter equipment in the vicinity of the front door 3 . The filter equipment includes a filter 4 , which may be a glass fiber mat or a polypropylene filter, and is placed in a filter frame 17 . The filter 4 is mounted in a filter tank 6 , which in this embodiment is configured as a recess and is located in a recessed portion 23 of the door 3 .

[0031] In principle, the filter tank 6 is configured in a manner suitable for the filter 4 and isolates the fresh air side 16 of the filter 4 in a practically flush manner with the filter tank 6 , however, at the air outlet of the filter 4 On side 8 a circumferential seal 1...

Abstract

The invention relates to a system for cooling electrical and electronic components and devices which are arranged in a housing. The invention is especially suited for outdoor cabinets and housings of telecommunications technology. The aim of the invention is to provide a cooling system into which an inexpensive filter can be inserted and arranged in such a manner as to allow an extremely good sealing. For this purpose, a filter trough is arranged in a housing wall or door, the filter being accommodated therein in a manner so as to be detached and replaced from the exterior and being sealed from the filter trough by means of a continuous seal on its air exit side.

Description

technical field [0001] The invention relates to a system for cooling electrical and electronic components and devices placed in housings according to claim 1 . Background technique [0002] The invention relates in particular to housings and cabinets for telecommunications technology, which are arranged outdoors as outdoor cabinets and housings. Such outdoor enclosures and cabinets are more or less exposed to atmospheric conditions and external influences and must be protected in such a way that external entities, dust, dirt, water and moisture cannot penetrate the interior and cause degradation or failure of components and devices structure or be sealed accordingly. In general, attention must be paid to protection regulations according to IP classification, eg IP protection value 55, ie housings and cabinets are dust-tight and must withstand water jets from any direction. [0003] An outdoor housing and cabinet system is known with a membrane filter in the air inlet of th...
