ABSTRACT:
A flow control panel includes a pair of upper and lower sheets arranged one above the other. The upper sheet has a plurality of integral ridges and a plurality of recesses between adjacent ridges. Likewise, the lower sheet has a plurality of integral ridges and a plurality of recesses between adjacent ridges. The upper and lower sheets are superimposed so that each of the upper ridges is positioned in respective one of the lower recesses between adjacent lower ridges to form a plurality of passages through which a flowing fluid medium flows. When a pressure increase occurs within the passages, the upper and lower sheets are relatively moved away from one another to increase the cross sectional area of the passages to accommodate such a pressure increase within the passages.
