Each panel is substantially uniform in size and of a shape that nests with horizontally adjacent panels, and there are a plurality of vanes disposed inside each panel. At least one of the vanes is at an angle to the horizontal and has a passage between the vane and an adjacent vane. The center of at least one panel in the second layer is horizontally offset from the center of a vertically adjacent panel in the first layer.
