Abstract
A heat exchanger with a sheaf of heat-exchanging pipes, with a chamber beyond each end of the sheaf, and with an ancillary-flow pipe extending approximately axially through the exchanger and parallel to the heat-exchanging pipes with its upstream and communicating with the entry chamber and its downstream and communicating with a mixing chamber by way of cylinder that has a larger cross-section than the ancillary-flow pipe. A structure for maintaining the medium flowing through the exchanger at a prescribed exit temperature is positioned at the downstream and of the ancilliary-flow pipe.
