1. An apparatus for heat exchange, having at least three flow devices through which at least one flowable medium (fluid) flows;

  • at least one fluid inflow device, at least one fluid collection and/or distribution device and at least one fluid outflow device for each of the flow devices through which substantially liquid fluids flow, wherein at least two flow assemblies are provided, each having at least two flow elements, which are arranged in such a manner that different fluids flow through them alternately, the flow elements belonging to at least one flow device through which substantially liquid fluids flow are connected in a substantially gastight and liquid-tight, positively locking and/or nonpositively locking and/or cohesive manner to at least one fluid collection and/or distribution device, the main directions of flow of all the fluids in the flow elements lie in planes that are substantially parallel to one another, at least two flow assemblies are directly connected in series in a positively locking and/or nonpositively locking and/or cohesive manner and/or flow-connected by means of fluid distribution devices, at least with respect to one flow device.
