Device for multi-stage heat exchange and method for producing one such device
First Claim
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.

Abstract
The invention relates to a device for multi-stage heat exchange and to a method for producing one such device, whereby at least three free-flowing media (fluids) are used in three flow devices subdivided into at least two heat-exchanging or flow modules. Said modules respectively consist of at least two flow elements that are arranged in such a way that different fluids alternately flow through the same. For essentially liquid fluids, the fluids are distributed to the flow elements by means of fluid collecting devices or fluid distributing devices connected in a gas-tight and liquid-tight manner. The main flow directions of all fluids in the flow elements are in essentially parallel planes. At least two flow modules are directly mounted in series and/or by means of fluid distributing devices in a flow-connected manner at least in relation to one flow device.

18. An apparatus, in particular the apparatus as claimed in
wherein at least one flow device has admixed with it, via at least one further inflow device, a fluid, in particular, although not exclusively, a fluid which corresponds to the fluid in this flow device.
-
20. An apparatus, in particular the apparatus as claimed in wherein,
wherein fluids are mixed in the heat exchanger, it being possible for different proportions of the overall fluid to flow through different flow elements.
-
25. A process for producing an apparatus for heat exchange, in which:
-
at least three flow devices are formed, in particular, although not exclusively, by punching out well-shaped metal plates, which form flow elements, with longitudinal-side openings being punched out, of which a first number of simple openings form fluid inlets and outlets with respect to adjacent flow elements, and sealing devices, in particular, although not exclusively, stamped projections in the corresponding flow element which adjoin the adjacent flow element in a cohesive and/or positively locking and/or nonpositively locking manner, in order to form passages in the corresponding flow element, through which passages flow elements adjacent to this flow element are flow-connected, being arranged around a second number of openings, wherein at least two flow assemblies are formed by in particular, although not exclusively, stacking the flow elements on top of one another, in which case the flow elements are to be arranged in such a manner that different fluids flow through them alternately, 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 in a manner flow-connected by means of fluid distribution devices, at least with respect to one flow device, joins selected from a group which includes soldered joins, welded joins or adhesively bonded joins being produced between the flow elements, fluid inflow, outflow, distribution and/or collection devices.
