Description
- The invention relates to a heat exchanger with which fluids can be very rapidly and uniformly cooled or heated.
- Heat exchangers are required in numerous industrial applications. Here, the trend is increasing towards ever higher heat transfer performance in the smallest possible space. These requirements are met particularly well by micro heat exchangers. In process technology, it is moreover desirable for very uniform heat transfer to take place, that is, to avoid so-called hot spots arising which could result in product damage due to an uncontrolled temperature increase.
- A microstructure heat exchanger made up of small pipes or hollow fibres located in a graphite matrix is known from
DE 100 22 972 A1. - Further, micro heat exchangers are constructed of multi-ply microstructured layers, wherein the individual layers each have a number of microchannels. The layers are arranged such that the microchannels of adjacent layers are aligned in simple cross-flow construction, parallel flow construction or counter flow construction. Such a micro heat exchanger is known from DE 196 08 824 A1.
- Counter flow heat exchangers achieve the highest heat exchange performance per exchange surface. However, the possibility cannot be excluded that inadmissibly high temperature differences occur at the inlet of the warmer fluid, leading to damaged heating fluid.
- In the parallel flow heat exchanger, on the other hand, the wall temperatures remain in a middle range at all positions on the heating surface. However, due to the rapidly decreasing temperature difference between the adjacent fluids, the heat exchange performance is relatively poor.
- In simple cross flow heat exchangers for micro heat exchangers as currently known, the heat exchange performance is between that of the parallel flow heat exchanger and the counter flow heat exchanger. However, the full heat exchange surface is not used efficiently here, as the temperature differences in a quadrant of the heat exchange surface become extremely small or cease to exist.
- Further, known micro heat exchangers have either insufficient or no heat insulation from the surrounding ambient, which has a particularly disadvantageous effect on modular micro reaction systems, as known for example from DE 202 01 753 U1, as it results in very intensive heat exchange with adjacent modules.
- The invention is based on the object of providing the highest possible heat transfer performance, that is, a large heat transfer surface, while achieving extremely small pressure loss both for the process fluid and for the heat transfer fluid.
- According to the invention, this is achieved in that the heat exchanger is constructed from a stack of films or plates in which channels for the fluids are embodied each lying adjacent one another, wherein the channels of the films or plates lying over one another intersect. Here, the heat transfer fluid flows into the channels of a film or plate lying adjacent one another in antiparallel branch flows, while in the film or plate lying thereabove and therebelow, the process fluid flows transverse to the heat transfer fluid and parallel in the channels lying adjacent one another. Due to the linear channelling in each case, the pressure loss in the heat exchanger is minimized.
- At each crossing point of heat transfer fluid and process fluid, for each branch flow of the process fluid over the whole volume of the heat exchanger, the device according to the invention leads to the inlet conditions of a counter flow heat exchanger having the known high temperature differences between heat transfer fluid and process fluid. Due to the numerous crossing points of heat transfer fluid and process fluid, an optimum temperature difference between heat transfer fluid and process fluid and thus an extremely high heat transfer performance per unit of volume and simultaneously absolutely uniform heat transfer over the whole volume of the heat exchanger, is hereby obtained over the whole volume of the heat exchanger.
- The present invention combines the advantages of a counter flow heat exchanger with the advantages of a cross flow heat exchanger.
- An exemplary embodiment of the invention is explained in more detail below with reference to the drawing, in which

FIG. 7 shows an exploded view of distributor plates, -
FIG. 8 shows a housing with a micro heat exchanger from a stack of films in a perspective cut-away representation, and -
FIG. 9 schematically shows an arrangement of a plurality of heat exchanger units according toFIG. 6 , which form a heat exchanger of greater capacity. -
FIGS. 1 to 4 schematically show the construction of amicro heat exchanger 1, whereinFIG. 1 represents a stack of films or thin plates F as indicated by dashed lines inFIG. 1 . In the individual films or plates, channels and throughholes are embodied, wherein the channels extending horizontally can be embodied in a film F for example by recesses which are covered by the surfaces of adjacent film F, so that a closed channel results. In the embodiment according toFIG. 1 , the lowest film of the stack of films is merely shown as a cover film for the bottom row ofchannels 3. However, another shape of channel formation in the individual films or plates F is also possible, for example in that a division extends between two adjacent films F in each case along the middle of the horizontally extendingchannels -
FIG. 1 shows as an example a flow pattern in which a process fluid P flows through thechannels 2 and a heat transfer fluid W flows through thechannels 3 extending transversely thereto. Thechannels 3 lie adjacent one another in a film F and form arow 30 of channels in each second film F. In the same way, thechannels 2 for the process fluid P are each formed lying adjacent one another in arow 20, asFIG. 2 shows, which represents a section along the line A-A inFIG. 1 . The process fluid P flows parallel through theadjacent channels 2 in each case, while the heat transfer fluid W flows antiparallel in two branch flows W1 and W2 through theadjacent channels 3, as the flow pattern inFIG. 5 shows schematically. The antiparallel flow of the branch flows of the heat transfer fluid can also be seen inFIG. 4 , which represents a section along the line B-B inFIG. 1 , whereinFIG. 4 only represents a partial sectional view, and the upper and lower edge areas of theheat exchanger unit 1 are not represented. - The supplying of the heat transfer fluid W takes place via
throughholes 4 in the films F, which inFIG. 2 form apipe 4 from bottom to top, extending transverse to the horizontally extendingchannels pipe 4 a, which is embodied by corresponding throughholes in the films F lying over one another and likewise extends in the plane of the drawing ofFIG. 2 from top to bottom or vice versa, transverse to each of thechannels adjacent channels 3 inFIG. 2 , through which the branch flows W2 flow from right to left, are fed by a pipe formed bythroughholes 5, which lies before and behind thepipe 4 a. The discharging of the branch flows W2 takes place throughpipes 5 a before and behind thepipe 4 inFIG. 2 , as can also be seen fromFIG. 6 . -
FIG. 1 showspipes channels pipe 7 and discharged throughpipe 8. - To clarify the course of flow, in
FIGS. 1 to 4 the direction of flow away from the observer is represented by an X and the direction of flow towards the observer by a dot. -
FIG. 5 schematically shows the flow pattern in the core portion of the heat exchanger with intersectingchannels upper row 30 ofchannels 3 inFIG. 1 and the process fluid P in therow 20 ofchannels 2 therebelow inFIG. 1 , without the channels themselves being represented.FIG. 5 therefore only shows by means of arrows the flow in the core portion of the heat exchanger, wherein the process fluid P flows parallel through each of thechannels 2 arranged in rows, and the heat transfer fluid W flows transverse thereto in antiparallel flow to the branch flows W1 and W2 in each case. -
FIG. 6 shows in a schematic perspective view aheat exchanger unit 1. The core of the heat exchanger is formed by the intersectingchannels rows adjacent channels 3, while the process fluid P flows in parallel flow through theadjacent channels 2. The supply and discharge of fluid takes place in each case on the outsides of the block-shaped arrangement of the intersectingchannels throughholes channels discharge pipes - In
FIG. 6 , thepipes 6 on opposite outsides of theheat exchanger 1 represented inFIGS. 1 and 3 are not shown. - If, in an alternative embodiment, the
micro heat exchanger 1 is used for cooling a process fluid P, then the heat transfer fluid W at first flows throughthroughholes 6, embodied inFIG. 1 on the outside of the supply anddischarge pipes channels pipes 6 with cold heat transfer fluid W. Following this, through a conduit (not shown) on the upper and lower side inFIG. 1 , the heat transfer fluid W is supplied via thethroughholes 4 to thechannels 3 extending out of the plane of the drawing inFIG. 2 , whereupon the heat transfer fluid emerges via the pipes embodied by thethroughholes 8. In this embodiment, the block of intersectingchannels pipes 6, wherein inFIG. 1 only two outsides are represented. The outsides of the heat exchanger core lying at the top and bottom inFIGS. 1 and 2 are also formed byrows 30 ofchannels 3, through which heat transfer fluid W flows. In this way, the cooling process fluid P in thechannels - When the
micro heat exchanger 1 is used for heating a process fluid P or as an evaporator, then the supply pipes of the heat transfer fluid W and of the process fluid P can be exchanged, so that in this case too, the cooler fluid flows into theouter pipes rows 30 of channels arranged on the outsides. - The described construction allows a plurality of adaptations, by changing the number of films F and of
channels micro heat exchanger 1 can be corresponding enlarged. - It is also possible to have both the process fluid P and the heat transfer fluid W flow antiparallel through the
respective rows channels adjacent channels 2, while the heat transfer fluid W flows transverse thereto in one direction in thechannels 3. - The
channels pipes 4 to 8 can be embodied such that they have the same cross section for their whole length. Hereby, a minimum pressure loss occurs during throughflow through the heat exchanger. However, it is also possible to embody thepipes 4 to 8 with a larger cross section than thechannels -
FIG. 8 schematically shows a stack of films FS in ahousing 100 in which pipes are embodied for the supply and discharge of process fluid P and heat transfer fluid W. As shown, thehousing 100 is constructed as a module which can be combined with other modules for the treatment of a process fluid P. However, theheat exchanger 1 described by means ofFIGS. 1 to 4 can also be used without ahousing 100, wherein inFIG. 1 on the upper and lower side in each case a conduit device is provided which has the connections for thepipes -
FIG. 7 shows in an embodiment distributor plates or films F1 to F3 in an exploded view, which represents the supplying of the heat transfer fluid W from the lower side of a stack of films and the distribution into branch flows W1 and W2. In the lowest film F1, athroughhole 10 is formed through which the heat transfer fluid W is supplied. From thethroughhole 10, achannel 10 a extends in the film plane, which branches into two channels 10 b, which in turn branch into two channels 10 c and so forth, until on the right-hand side inFIG. 7 the number of pipes 10 e is available which is required for the supplying of thechannels 3 of arow 30 for the heat transfer fluid in the core portion of the heat exchanger. In the film F2 lying thereabove,throughholes 5 are embodied in a row, which lie opposite the ends of the individual pipes 10 e, so that the heat transfer fluid W, as indicated by dashed lines, can flow upward through thethroughholes 5. In film F2, atalternate throughholes 5 apipe 11 is formed branching off, which leads in the film plane to the opposite side of the core portion of theheat exchanger unit 1. In the film F3 lying thereabove, a row ofthroughholes 4 is embodied which lie opposite the ends of thepipes 11, so that a branch flow W1 of the heat transfer fluid can flow upwards through thethroughholes 4. The opposite row ofthroughholes 5 in the film F3 lies opposite theholes 5 in the film F2, from which nopipes 11 branch off, so that a branch flow W2 flows upwards through thethroughholes 5. - Above the film F3, a channel arrangement corresponding to
FIG. 4 can be embodied in the next film plane, in which the two branch flows W1 and W2 flow in counter flow through thechannels 3. To simplify the representation, in the films F1 to F3 thereturn pipes throughhole 10. - The supplying of the process fluid P in the embodiment shown takes place from above by an arrangement of distributor plates corresponding to that in
FIG. 7 , wherein the lowest plate F1 inFIG. 7 forms the uppermost plate for the guiding of the process fluid. As the process fluid P flows in parallel flow through thechannels 2, it is not necessary to provide a distributor plate corresponding to the distributor plate F2. Rather, at the uppermost film corresponding to the film F1, a film with throughholes corresponding to film F3 can be joined, in which rows ofthroughholes throughholes FIG. 7 . - In the representation in
FIG. 7 , to simplify the representation, thepipes 6 lying outside inFIGS. 1 and 3 are not shown, which are also embodied by throughholes in the individual films F. - In
FIG. 7 , the films F1 to F3 are shown discoidally, while inFIGS. 1 to 4 and 6, in each case only one block-shaped arrangement ofchannels pipes 4 to 8 is represented. In the same way, the channels and pipes shown in these Figures can be embodied in discoidal films, so that a round stack FS of films F results, as shown inFIG. 8 . - In the heat exchanger shown in
FIG. 8 , the heat transfer fluid W is supplied from below and discharged from above, so that any air contained in the heat exchanger is displaced out upwards. The process fluid can be supplied from above and discharged on the lower side. However, another flow direction of the fluids P and W is also possible. For example, the heat transfer fluid W can be supplied from above and also discharged from above, while the process fluid P is supplied from below and discharged from below. -
FIG. 9 schematically shows an arrangement of individualheat exchanger units 1, of which one is shown inFIG. 6 . For very great heat transfer performance or large fluid flows, a plurality of suchheat exchanger units 1 can be arranged adjacent and over one another, asFIG. 9 shows, wherein above a lower ply of heat exchanger units la a further ply of heat exchanger units 1 b and 1 c is arranged. Hereby, the heat transfer performance can be multiplied without substantially increasing the overall pressure loss, in that the individualheat exchanger units 1 are fed fluidically in a parallel manner. In other words, each individualheat exchanger unit 1 can be supplied with fluid by means of distributor plates corresponding toFIG. 7 , wherein the different distributor plates can be supplied with fluid centrally by an additional distributor plate. Between the individual plies of heat exchanger units 1 a, 1 b and 1 c, distributor plates can be provided in which throughholes are embodied for forming pipes leading vertically upwards between the heat exchanger units 1 a, through which pipes the heat exchanger units 1 b and 1 c are supplied with the fluids W or P. In the same way, distributor plates can be provided on the upper side of the block of a plurality of heat exchanger units. - According to a simpler embodiment, for increasing the heat transfer performance only one group of heat exchanger units 1 a can be supplied parallel, which corresponds to the lower ply in
FIG. 9 . In such an embodiment, additionally to the distributor plates shown on the upper and lower side inFIG. 7 , a further distributor plate can be provided from which theindividual throughholes 10 are supplied with fluid, wherein this additional distributor plate has a central fluid supply from which channels lead off to theindividual throughholes 10 of the individual heat exchanger units 1 a, corresponding to the film F1 shown inFIG. 7 . - To determine the temperature of the fluids, advantageously temperature sensors can be integrated directly adjacent the microstructured films or thin plates.
- The term fluid or process fluid is to be understood broadly according to the invention and comprises liquids and gases as well as emulsions, dispersions and aerosols. The device can be used both for cooling and for heating.
- Microstructured channels means structures which are smaller than 1 mm in at least one spatial dimension. The walls between the microstructured channels are preferably between 10 μm and 500 μm thick.
- Advantageously, the films or thin plates with which the micro heat exchangers are joined together, are composed of sufficient inert material, preferably metals, semiconductors, alloys, high-quality steels, composite materials, glass, quartz glass, ceramic or polymer materials, or of combinations of these materials.
- Methods which can be considered as suitable for fluidically leak-proof joining of the films or thin plates are for example pressing, riveting, bonding, soldering, welding, diffusion soldering, diffusion welding, and anodic or eutectic bonding.
- The structuring of the films or thin plates can take place for example by milling, laser ablation, etching, the LIGA method, galvanic casting, sintering, die-cutting or deformation.
- For the relevant person skilled in the art, it can easily be understood that the device can be used not only as a micro heat exchanger but that, for example, an application as an evaporator or condenser of a combination thereof (rectification) is also possible.
- Further, the construction of a heat exchanger according to the invention is not only suitable for micro construction. It can also be used for larger-dimensioned heat exchangers. These can be constructed for example, from thicker plates in which channels are stamped, milled or imprinted and bores are embodied instead of throughholes. Such structures can also be formed on the plates by spark erosion.
- The material of the plates or films F preferably consists of inert material or material which is sufficiently inert in relation to the fluids used.
