I may be missing the point here, and if so would gladly be educated, but I would imagine this would be set up in a way that the inlet air would be forced to travel along each of the interconnecting pipes to maximise the effective contact area between the air and the ground i.e. the header pipes would be blocked at specified points to force air through the full length of the pipe network. If it wasn't configured like that I would imagine the air would simply short-circuit through one of the larger header pipes which wouldn't give much heat transfer surface area (and there would be no point in the interconnecting pipework)?
