Definitions
- the present invention relates to a method for heat transfer with a fluid in a microstructure body a variety of microchannels for the removal and supply of the Fluids as well as one that transfers the thermal energy to the fluid Energy carrier and a microstructure body for exercise of the procedure.
- the invention proposes the features before, cited in the characterizing part of claim 1 are. Further advantageous features for the solution are cited in the characterizing parts of the subclaims.
- Microstructure bodies of the type mentioned are generally characterized in that either the characteristic hydraulic channel diameter d i or the channel dimensions a i , where a i is the largest dimension of a microchannel perpendicular to the fluid passage i, of all microchannels of at least one fluid passage i are less than 1000 ⁇ m.
- the smallest wall thickness b i that is to say the smallest distance between individual fluid passages, should also be chosen to be less than 1000 ⁇ m, preferably less than 200 ⁇ m.
- the specific heat transfer area can reach values greater than 100 cm 2 / cm 3 . This results in an overall increase in volume-specific heat transfer performance by at least a factor of 100 compared to conventional heat exchangers.
- the experimental data obtained from microstructure bodies for heat transfer result in heating rates of up to 10000 K per second with dwell times down to a few milliseconds. Therefore, a liquid flow of 400 kg / h in a microstructure body of 1 cm 3 active volume at 6 bar inlet and 1 bar outlet pressure can be heated by 30 ° K in 3 milliseconds. Throughputs of approx. 4000 kg / h result for larger microstructure bodies with an active volume of 27 cm 3 .
- the active volume of a microstructure body is to be understood as the volume in the interior in which the microchannels run, the volume of top and side plates and that of the connections not being included in the calculation.
- the fluid to be heated is passed through at least one level or layer of a microstructure body with a large number of adjacent microchannels or micro breakthroughs, their transverse dimensions
- smaller than 1000 ⁇ m are preferred smaller than 500 ⁇ m
- immediately adjacent to it fluid-carrying level at least one layer with at least an electrically heated heating element is arranged, which electrically insulated from the material of the fluid level is.
- many levels or Alternating layers with micro breakthroughs for the fluids with layers with electrically heated heating elements into one compact unit arranged as in those described later Figures 1 and 2 shown in principle.
- the heating elements can be used depending on the application Current flow in series or in parallel or in a combination of which are switched.
- Fluids can have several in the heating layers Heating elements, seen in the direction of flow, one behind the other be arranged, the different electrical Deliver services.
- the fluid-carrying microstructures, - seen again in the direction of flow -, on different temperatures are heated. Thereby can be a temperature profile in the microstructure body Performing a process in the flowing fluid become. This can be important if e.g. B. in the microstructure body a chemical, endothermic process is performed at which the temperature in the direction of flow first kept constant and then increased in a targeted manner got to.
- FIG. 1 Such a microstructure body 1 is now shown in FIG. 1 shown schematically, installed in the eleven double foil pieces are welded together and one above the other stacked eleven rows of microchannels 2 result.
- Each the film double piece contains a multiplicity of microchannels with a width and height of 150 ⁇ m and a length of 22 mm. Their hydraulic diameter is 133 ⁇ m.
- the eleven welded together Foil double pieces are each on their Edges on top of each other with ten spacers 3 to one Block welded so that 3 flat by the spacers Cavities 4 are formed between the film double pieces, in which plate-shaped, ceramic electrical heating elements 5 can be used.
- microstructure body 1 On the face of the microstructure body 1 with the openings of the microchannels 2 are hollow adapter pieces 6 through which the to be heated Fluid 7 is passed into the microchannels 2.
- the Microstructure body 1 is at the top and bottom with two end plates 7 completes that with the structures of the film double pieces and the spacers 3 to a closed Block are diffusion welded.
- FIG. 2 Another embodiment of a microstructure body is shown in Figure 2. With this microstructure body 13 resistance heating cartridges 9 are used for heating. Between two steel plates 10 as a lid and bottom of the microstructure body are each several with microchannels 14 structured steel foils 11 and spacers 12 layered as heated layers in alternating order and diffusion welded together. In the microstructured foils 11 are each a large number of microchannels 14 for the fluid 7 with approximately those already introduced dimensions. The heating cartridges 9 are inserted into holes in the spacers 12. The Fluid connection to the microchannels 14 does not take place by means of Standard fittings shown as connecting pieces serve. Depending on the number and the output of the heating cartridges 9 can the total performance of such a microstructure body 13 in the range of a few 100W to several kW.
