The invention relates to a heat exchanger in modular construction, in particular for facilities operated using large load and/or temperature changes, having an external shell and a number of heat exchanger modules, wherein each heat exchanger module, which is either a preheater, evaporator, or superheater module, has an entry manifold, and exit manifold, and meandering pipes, through which the heat-absorbing medium, in particular water, flows from the entry manifold to the exit manifold, and the heat exchanger modules are also situated in a shared external shell, so that they have the same heat-dissipating medium flowing around them, the evaporator modules being connected in parallel via a steam-collecting drum situated outside the external shell.

Heat exchanger in a modular construction

A heat exchanger has a container with an outer mantle and pipes positioned in the container for conveying a heat-receiving medium through the container. The heat-transferring medium flows exterior to the pipes in counter flow to the heat-receiving medium in the pipes. A common inlet tube is connected to the container and communicates with the pipes for introducing the heat-receiving medium. A common outlet tube is connected to the container and communicates with the pipes for removing the heat-receiving medium from the pipes. The pipes extend meander-shaped within the container. The common inlet tube penetrates the outer mantle on opposite sides and has an inflow end and a remote end. The inflow end is pressure-tightly connected to the outer mantle. The common outlet tube penetrates the outer mantle on opposite sides and has an outflow end and a remote end. The outflow end is pressure-tightly connected to the outer mantle. First and second receiving chambers are pressure-tightly connected to the exterior of the outer mantle. The remote end of the common inlet tube is received in the first receiving chamber and the remote end of the common outlet tube is received in the second receiving chamber.
