A substantially four-sided housing which forms a chamber therewithin, the housing being open on two opposite sides. A tube nest is replaceably disposed within the chamber, the nest comprising a plurality of coolant tubes each of which tubes has a 180 DEG -bend midway between opposite open ends thereof. A waterhead encloses the open tube ends which are all arrayed at one of the open sides of the housing. The waterhead has inlet and outlet apertures therein for admitting coolant into and from the open tube ends. The housing further includes inlet and outlet fluid plenums at either ends thereof with ports therein for admitting and venting fluid to and from the heat exchanger. Also, walls of the exchanger structure have means for directing fluid away therefrom and into the tube nest.
