A heat exchanger, especially a condensate-evaporator or like unit for a gas-rectification column in which a prismatic heat-exchange body is surrounded by a cylindrical housing such that sectoral compartments form passages for the fluids traversing the heat exchanger body. The body of the heat exchanger consists of a stack of plate pairs, the plates of each pair being corrugated such that alignment of the corrugations produces tubes. The tubes of the stacked arrays are staggered from one array to the next and communicate via a space at the bottom of the cylinder housing, with one of the sectoral compartments. The device functionally connects but physically separates the high-pressure and low-pressure sides of a column.
