Abstract (en)
[origin: EP0388471A1] An: indirect evaporative cooling method and apparatus, e.g. for a heat exchanger system, consists of passing the medium to be cooled through a dry channel in contact with one heat exchanging surface and cooling gas through another dry channel in contact with a second heat exchanging surface, with a return flow through a moist channel of the same length as the dry one by means of suction. The apparatus comprises a housing (12) with outlets and inlets for the medium to be cooled and the cooling gas, containing a capillary-porous material (10) in which the through moist channels (22) and dry cahnnels (23, 24) are located. Channels (22, 24) are linked to one another and to an outlet duct (17) containing an extractor fan (32) to intensify the cooling process. The cooled substrance passes along a dry channel (23) and on to a consumer. At the same time the cooling gas passes directly along a dry channel (24) and then turned through 180 deg. to pass back along a moist channel, through which' is drawn by the extractor fan.
