    a plurality of spacers separating said first and second corrugated sheets to provide an airflow cavity therebetween, said plurality of spacers being disposed transversely to directions of corrugation of said first and second corrugated sheets;

    a heat exchange means formed directly in said first and second corrugated sheets for dissipating any heat contained in any hot air located between said first and second corrugated sheets into atmosphere by said first corrugated sheet and for guiding any hot expanded air upwardly from below said second corrugated sheet to flow between said first and second corrugated sheets and to be ultimately discharged into the atmosphere;

    wherein said heat exchange means includes a first plurality of apertures disposed in said first corrugated sheet and a second plurality of apertures disposed in said second corrugated sheet;
