Beschreibung
Zusammenfassung:	Una placa (6) para intercambio de calor y enfriamiento evaporativo indirecto de al menos una corriente de fluido, consistiendo la placa en: a) un costado seco (9) que tiene baja permeabilidad a un líquido evaporativo; y b) un costado húmedo (10) diseñado para que tenga húmeda dicha superficie del costado húmedo por la acción de un líquido evaporativo; donde el costado seco de la placa forma al menos un primer canal (4) para guiar la corriente de gas activo (2) y segundos canales (3), generalmente en paralelo con respecto al primer canal, para guiar una corriente fluida del producto (1); y caracterizado por el hecho de que la placa además forma al menos una perforación (11) a través de la placa en el primer canal para permitir que la corriente activa sea transfiera al costado húmedo de la placa. An improved method and apparatus for indirect evaporative cooling of a fluid stream to substantially its dew point temperature. Plate heat exchanger has perforations 11 and channels 3, 4 and 5 for gas or a low temperature for liquids on a dry side and wet side. Fluid streams 1 flow across the dry side 9, transferring heat to the plate. Gas stream 2 flows across the dry side and through perforations to channels 5 on wet side 10, which it then cools by evaporative cooling as well as conductive and radiative transfer of heat from plate. A wicking material provides wetting of wet side. In other embodiments, a desiccant wheel may be used to dehumidify the gas, air streams may be recirculated, feeder wicks 13 and a pump may be used to bring water from a water reservoir, and fans may be used to either force or induce a draft. The wicking material may be cellulose, organic fibers, organic based fibers, polyester, polypropylene, carbon-based fibers, silicon based fibers, fiberglass, or combinations of them. The device may be operated in winter months to scavenge heat from exhaust gases of a space and thus pre-heat fresh air, while simultaneously humidifying the fresh air.
