- the fluid channels 97 and 103 are in communication with the respective openings fürströmbar ausgestaltet, wherein the two flow channels 97 and 103 are separated by the interposition of the disc 91, not shown, but from each other,
- FIG. 12 shows the arrangement of disk pairs and disk groups in adjacent arrangement, wherein the disk pairs of the disks 82 are arranged in the air flow direction before the arrangement of the disk groups of the disks 90, 91, 92.
- FIG. 13 shows this from the other side, so that it can be seen that first the flow channel 85 is surrounded by air before the flow channel 103 is flowed around.
- FIG. 14 again shows this in section, wherein it can be seen that the flow channel 85 is formed by two discs 82, wherein the flow channels 97 and 103 are formed by the discs 90, 91 and 92, the two flow channels 90 and 103 in FIG In a direction perpendicular to the direction of air, in sum, occupy only the space that is occupied by the air channel 85 of the two discs 82.
- FIG. 17 shows a heat exchanger 300 with a heat transfer core, wherein the heat transfer core 301 is formed by a plurality of parallel pairs of discs consisting of two discs which form two flow paths between each disc and the partition wall with the interposition of a partition wall.
- the heat exchanger 300 has a plurality of disk pairs 302, which are arranged adjacent to one another, wherein corrugated fins 303 are preferably arranged between the disk pairs.
- Each disk pair see also FIG. 18, has two inlet openings 304, 305, 306, 307 designed as wells at a first end area and at a second end area.
- a cup of an end region 304 or 305 forms an input-side cup, wherein the output-side cup associated with the flow path 308 in the other end region is arranged.
- an inlet-side and an outlet-side cup are provided as inlet or outlet of the heat exchanger on each side in each end region.
- FIG. 18 shows three pairs of disks, each shown at a distance, which consist of two disks and an intermediate wall, these pairs of disks being arranged to form a disk package 310.
- the disk 31 1 forms a flow channel 313 and the disc 312 a flow channel 314.
- These flow channels are formed by embossments between two wells, only two of the four shown cups are connected to the flow channel.
- the cup 315 and the cup 316 are connected to the flow channel 313, wherein the cups 317 and 318 are not connected to the flow channel 313.
- the cup 319 and the cup 320 are connected to the flow channel 314, with the cup 321 and the cup 322 not connected to the flow channel.
- FIG. 22 shows a disk package with three pairs of disks in a perspective representation, wherein only the uppermost region of the disk package 340 is shown.
- FIG. 23 shows a section according to section 1 of FIG. 22 and
- FIG. 24 shows a section according to section 2 of FIG. 22. It can be seen that in each case a pair of discs 350, 351 is provided with an intermediate layer 352, wherein between the discs 350 and 351 a flow kana! 353 is disposed on one side of the partition wall 352, while a second flow channel 354 is disposed on the other side of the partition wall. This pattern is repeated for each disk pair of the three disk pairs shown, so that two flow channels 354, 353 are arranged on both sides of the partition wall 352 between the disk pairs.
- FIG. 24 also shows the flow channels 353 and 354 each arranged on one side of the partition wall 352.
- FIG. 25 shows the disk package 340, wherein FIG. 26 shows a section according to section 3 of FIG. 25 and FIG. 27 shows a section according to section 4 of FIG. 25.
- the discs 350 and 351 are shown at intermediate would be the partition 352, wherein each of the flow channels 354 and 353 can be seen. It can be seen in section 3 that the flow channels do not extend over the full width of the disc, wherein the flow channels in the figure 27 extend substantially over the entire disc. This is due to the fact that the channel profile to the cup must be returned from the substantially full width to about half the width.
- the design of the pairs of disks makes it possible to form a heat exchanger consisting of a series of disk pairs, each of which forms both a first flow channel connected to an inlet header and an outlet header and a second flow channel likewise provided with an inlet header and an outlet header is.
- the cups which are connected in series with each other, the respective inlet collector and outlet collector.
- the respective disk pair consists of two opposing disks, wherein between the two disks, a partition wall or a partition plate is provided, which separates the flow channels of the respective disks from each other. When the flow channels are countercurrently flowed, the separating plate serves to separate the opposing fluid streams through the flow channels, the cups of the individual pairs of discs arranged in series with one another forming the fluid inlet collector or the fluid outlet collector.
- FIG. 28 shows the schematic arrangement of disk pairs 400, 401, which have an inlet-side cup 402 and an outflow-side cup 403.
- the fluid flow takes place from the inlet-side bowl 402 through the flow channel 401 to a passage 404, from where the fluid can flow into the second flow channel 400 in order to flow to the bowl 403.
- this is carried out in each case, the two flow channels 400 and 401 being operated in countercurrent to one another.
- FIG. 29 shows this in an enlarged view.
- the pair of discs 401, 400 is provided with ribs 405 on both sides for the flow around air.
- the invention relates to a heat exchanger with internal integrated heat transfer by means of two in a tube in the counter-current flow channels.
- the heat exchanger consists of a series of disk pairs, each half in each case a first connected to the inlet header or -napf
- the pair of discs is in turn made of two facing discs and an intermediate therebetween separating plate composed.
- the separating plate is used to separate the
- the interconnected cups of the arrayed pairs of discs form on the one hand the fluid inlet header for distributing the fluid to the individual first flow channels, and on the other hand the fluid outlet header for collecting the fluid from the individual second
- Fluid inlet disc 31 1 is a flow connection between the flow channel 313 and the fluid inlet cup coined, wherein the fluid disc 312 a
- connection embossings can be carried out alternately in the disk tool and thus both disks can be produced in one and the same tool with a replacement set. This reduces tool costs and increases the number of identical parts.
- the heat exchanger described above is flowed through so that a fluid, such as refrigerant or coolant, etc. on the first collector as
- the connecting element between the two opposing collectors on the underside of the block can be a separate connecting part or else in a side part with integrated deflection channel or the like. be executed.
- the fluid is distributed simultaneously via the inlet header to all first disc channel halves 31 1 arranged in parallel and, according to the deflection, distributed further to all second disc channel halves 312 by means of a connecting element.
- Disc channel halves 312 the fluid is forwarded to the next block and there again the same distribution process is continued as in the first block.
- the flow channel eübertrager in particular the disc evaporator, can alternatively be carried out in single-tank design, ie with only one tank on one side of the Würmeübertragers
- the interconnection of the individual modules can be varied depending on the arrangement and / or embodiment.
- the temperature of the flowing refrigerant through the evaporator sets much faster at a lower average temperature level and the overheating zone can be reduced to a minimum in the evaporator. This results in a high driving average temperature gradient and an associated increase in performance.
