Abstract
A heat exchanger that is constructed with a heat exchanger shell having inlet and outlet plenums and fluid inlet and outlet ports, and a tube sheet construction disposed in the heat exchanger shell. The tube sheet construction includes at least two separate tube sheets and a plurality of tubes that extend between the separate tube sheets. Each tube sheet includes at least two planar tube sheet segments and an interstitial layer disposed between the at least two tube sheet segments, and at least one sensor element supported by each of the interstitial layers. A control monitor controls flow through the shell by a feedback control from the sensor to an inlet control valve and/or a stimulus device excites the media layer.

A tube sheet construction that is comprised of a plurality of separate planar tube sheet segments, multiple holes being provided in each planar tube sheet segment in a predetermined pattern, each hole for accommodating an elongated tubular element, all of the tube sheet segments being aligning so that the hole pattern of each segment aligns with the hole pattern in all other segments, an interstitial layer disposed parallel with and between two adjacently disposed tube sheet segments, at least one sensor element supported by the interstitial layer, and fasteners for securing all of the planar tube sheet segments and the interstitial layer together and arranged so that all planar tube sheet segments and said interstitial layer are all maintained in intimate contact so as to form a solid tube sheet structure.
