Exemplary embodiments provide an advanced cooling system for an electronic display having a plurality of open loop fluid flow paths as well as a closed loop fluid flow path. The open loop divides a fluid, such as ambient air, among a series of sub-paths including front and rear open loop layers and a heat exchanger. The first and second open loop layers may comprise a corrugated element, forming peaks and valleys. The peaks and valleys of the front and rear layers may be arranged such that they do not align. A section of the rear open loop layer may be sealed from open loop flow. The closed loop preferably passes through an electronics compartment and the heat exchanger, also passing in front of the electronic display.
