ABSTRACT:
A flat pipe includes a hollow body having a pair of upper and lower walls extending substantially parallel to each other, and opposite lateral sides joined thereto, and a plurality of spacers closely fit between the upper and lower walls of the body and interconnected by a permeable sheet. The spacers are arranged at equal intervals to define a plurality of parallel fluid passages. The spacers are fused to opposite sides of the sheet in alternating relationship so that the sheet is inclined between adjacent spacers. The spacers are resistant to compression and deformation.
