Abstract:
1. A heat exchanger for attachment to an equipment cabinet, said heat exchanger comprising: a heat exchanger enclosure containing a heat exchanger core comprising a plurality of thermally conductive plates situated between opposing front and back sides of the heat exchanger enclosure, the heat exchanger enclosure further comprising a wet side input port through said front side and a dry side input port through said back side, the wet side input port and the dry side input port being located on an upper region of the heat exchanger enclosure; a first fan directing air from outside the equipment cabinet through the heat exchanger core and back to the outside of the equipment cabinet, air from the first fan being directed to a plurality of first air flow paths, each of the first air flow paths being between major surfaces of adjacent ones of the plurality of thermally conductive plates; and a second fan directing air from inside the equipment cabinet through the heat exchanger core and back to the inside of the equipment cabinet, the first fan and the second fan being arranged back-to-back with each other, air from the second fan being directed to a plurality of second air flow paths, each of the second air flow paths being between major surfaces of adjacent ones of the plurality of thermally conductive plates; wherein said back side is adapted to be attached to an external wall of the equipment cabinet, such that air from inside the equipment cabinet is drawn from the equipment cabinet by said second fan through an opening in the equipment cabinet external wall and into said heat exchanger enclosure through said back side, without inflow of air from outside the equipment cabinet.
