Abstract
The heat exchanger comprises at least one heat-transfer wall which forms a separation between a hot primary fluid and a secondary fluid to be heated. Each heat-transfer wall is either a vertical cylinder having a cross-section in the form of a circle with a wavy profile in the case of a tubular heat exchanger or a vertical rectangular plate having wavy corrugations in the case of a plate-type exchanger, a series of assembled plates being intended to form leak-tight compartments for receiving primary fluid and secondary fluid in alternate succession. The secondary fluid is introduced into the upper end of the heat-transfer wall in the vicinity of the wave crests of the wall face which is directed towards the fluid.
