Abstract: The present invention is an indirect evaporative cooling module preferably made from extruded, twin-walled, corrugated, fluted plastic sheeting. Sheets of this corrugated material are cut into plates which are preferably laminated together to form the primary and secondary passages that comprise the heat exchanger core. These passages can be configured any number of ways, from vertical to horizontal to diagonal, and flow through these passages can be cross-flow, counter-flow and even baffle-flow. Increased heat exchange efficiency is achieved through a variety of ways, for example, by including an efficient water distribution means at the top of the heat exchanger, evaporative mesh extending through and below the heat exchanger for water distribution and pre-cooling, the creation of top and bottom heat exchange chambers by channeling water directly to the bottom zone of the heat exchanges passages, and roughening the surface of the sheets to increase heat transfer and to increase surface area.

Each of the flow passages has a circular-shaped cross-section while the non-flow passage has a polygonal-shaped cross-section, so that a wall thickness of the non-flow passage is made thinner than that of the flow passages. Therefore, weight of the flat tube is decreased, while sufficient strength thereof is maintained.

Abstract: A high efficiency modular OLF heat exchanger with heat transfer enhancement is disclosed. The OLF heat exchanger has an oblique louver fin provided with oblique strips. The oblique louver fin thus effectively forms transverse and longitudinal vortexes in a main gas flow while breaking the boundary layer of the gas flow, thus having an improved heat transferring effect.
