In this case, the third pipe is preferably made of a steel, and the third collector and the second pipes and the inlet nozzle made of aluminum. The second

Pipes can then be connected to the third collector e.g. be welded or integrally formed on this. Furthermore, the second pipes can be welded to the respective inlet nozzle or integrally formed on the respective inlet nozzle.

According to one embodiment, it is also possible to dispense with individual or all connecting elements, wherein then preferably the components to be joined together are made of the same material or from

Materials that allow a direct connection of the respective components. In this case, a direct connection is understood as meaning a connection which does not have or requires a separate connection element which is connected to the two components and is arranged between them. A direct connection in this sense is in particular a material connection between the relevant components (for example collector, pipeline), e.g. a welded joint. Furthermore, there is a direct connection when the two components are e.g.

are integrally formed on each other.

In particular, can be dispensed with the connecting elements according to an embodiment of the invention, when the jacket of the heat exchanger and the other Components, such as pipes, collectors, heat exchanger blocks made of aluminum or the same (in the sense above) material are made.

Furthermore, it is provided according to a preferred embodiment of the invention that the second collector is mounted on the jacket of the heat exchanger, and preferably with a guide bearing, which is preferably attached to an inner side of the shell of the heat exchanger. The guide bearing is designed to prevent displacements of the second collector transversely to the extension means as well as heat-induced displacements in or against the latter

FIG. 1 shows in connection with FIG. 2 a block-in-shell heat exchanger 1 according to the invention. The heat exchanger 1 has a jacket 3 which extends along a longitudinal or cylindrical axis L which extends along the horizontal at a heat exchanger 1 arranged as intended , The jacket 3 defines a jacket space M, in which a plate heat exchanger 2 is arranged. This has a cuboid heat exchanger block 20, which is e.g. alternately arranged side by side and in particular vertical first and second

Heat transfer passages 201, 202, which are each designed to receive a first and second medium S, S ', so that the two media can exchange heat indirectly. The heat transfer passages 201, 202 are bounded in each case by two parallel separating plates 203 (the two outermost separating plates 203 of the block 20 are referred to as cover plates), between each of which a heat conducting structure 205 is arranged, which in the present case is designed as a so-called fin, ie as a corrugated or folded sheet metal, so that together with the respective two separating plates 203 a plurality of parallel channels for the respective medium S, S 'is formed. As indicated in FIG. 2, the first heat transfer passages 201 are open toward the top 20c and bottom 20d (not shown). That is, there are corresponding inlet openings on the underside 20d, via which the first medium S fed into the jacket space M, which forms a bath around the block 20, can enter and rise in the first heat transfer passages 201 (so-called thermosiphon effect ) and can emerge from the first heat transfer passages 201 at the upper side 20c via corresponding outlet openings O ", for example as a liquid and / or gaseous phase toward the sides 20a, 20b, the first and second heat transfer passages

201 closed by so-called edge or end strips (side bars) 204. The second heat transfer passages 202 are additionally closed at the top and bottom by such end strips 204. The components of the plate heat exchanger 2 such as e.g. the partition plates 203, the fins 205, the side bars 204 and the collectors 21, 22 are preferably made of aluminum. The partition plates 203, side bars 204 and fins 205 are preferably soldered together in an oven. As it rises in the heat exchanger block 20, the first medium S is brought into indirect heat transfer with the second medium S ', e.g. is conducted in countercurrent in the respective adjacent second heat transfer passages 202. As a result, the first gaseous second medium S 'is cooled and in particular liquefied, whereas the first medium S is heated and optionally evaporated. A resulting gaseous phase of the first medium S accumulates in the shell space 3 above the plate heat exchanger 2 and can be deducted from there. Preferably, the at the top 20c of the

Plate heat exchanger 2 together with the resulting gaseous phase leaking liquid phase of the first medium S in the surrounding the plate heat exchanger 2 bath returned.

For feeding the second medium S 'into the second heat transfer passages

202 of the heat exchanger block 20 is fixed to a first side 20 a of the block 20, which is perpendicular to the top 20 c, a first collector 21 which extends along an extension direction E over the entire first side 20 a and in Fluid communication with the individual second heat transfer passages 202 is, so that in the first collector 21 fed second medium S 'can get into the passages 202. Furthermore, at least one first inlet pipe 31 is fluid-connected to the first collector 21, the first inlet pipe 31 being arranged tangentially with respect to the first collector 21 and perpendicular to the first collector pipe 21

 Extending direction E runs, preferably along the vertical. The first inlet port 31 is further connected to a second pipe 42, which in turn opens into a third collector 23, which is designed hollow-spherical. Furthermore, a second (or more) inlet port 32 may be provided, which is arranged parallel to the first inlet port 31 and also opens into the first collector 21. The second inlet port 32 is then in turn

Fluid connection with another second pipe 43, which opens into the third collector 23.

The third collector 23 is in turn connected to a third pipe 44 in

Fluid connection, which is led out through an associated passage opening O 'of the shell 3 of the heat exchanger 1 from the jacket space M (the inlet port 31, 32, the two second pipes 42, 43 and the third collector 23 are thus arranged in the shell space M of the heat exchanger 1).

The second medium S 'can accordingly, in particular as a gaseous phase, passed through the third pipe 44 into the third collector 23 and from there via the second pipes 42, 43 into the first collector 21 and into the second

Heat transfer passages 202 are fed.

The flexibility for the expansion compensation is provided completely above the top 20c of the block 20 by the second pipes 42, 43 outgoing from the respective inlet port 31, 32 are first arcuately guided over the top 20c and then open into the third collector 23. The top 20c of the block 20 is at the level of the central longitudinal axis L of the shell 3 and the larger shell volume compared with the volume vertically below the block 20 is located above the top 20c and allows flexible routing. In addition, the stubs 31, 32 or second pipes 42, 44, which pass radially from the spherical collector 23 at any position, also permit flexible cable routing, with the required wall thickness according to ASME VIII for the

Internal pressure about half the wall thickness compared to a cylindrical collector needed.

The fact that the inlet ports 31, 32 tangentially to the first

Collector / header 21 also allows a conduit with at least two bends (curved portions of the second pipes 42, 43) and as a result allows a plate heat exchanger 2, which is hardly longer along the longitudinal axis L than the block 20 with the two collectors 21, 22. Thus, the jacket 3 or Kettle is very compact dimensioned with small dimensions and correspondingly low refrigerant demand. As shown in Figure 1, there are at least two different configurations, as far as the arrangement of so-called connecting elements 52, 53 and 54, which are also referred to as transition joints. The connecting elements 52, 53, 54 are used for a change of material between aluminum and steel. In each case, there is that end region of a connecting element 51, 52, 53, 54, which is to be connected to aluminum, made of aluminum, wherein furthermore that end region of the respective Verbindungselemenes 51, 52, 53, 54, which is to be connected to steel, consists of steel ,

Such connecting elements 52, 53 may be connected with respect to the first header 21 either between the inlet ports 31, 32 and the associated second

 Pipes 42, 43 may be arranged, in which case the inlet nozzle 31, 32 and the first collector 21 are preferably made of aluminum and the second

Pipes 42, 43, the third collector 23 and the third pipe 44 made of steel. The connecting element 54 can be omitted.

Alternatively, the connecting elements 52 and 53 can be omitted. Here, the inlet ports 31, 32, the second pipes 42, 43 and the third collector 23 are made of aluminum. A connecting element or transition joint 54 (see the dashed line of Figure 1) then connects the third collector 23 with the third pipe 44, which is then preferably made of steel and from the

Mantle space M is led out (see above).

As can be seen from Figure 1, the first collector 21 is disposed on the first side 20a of the block 2 at the edge to the top 20c. The second collector 22 on the second side 20b of the block 20 opposite to the first side 20a of the block 20 in the direction of the longitudinal axis L and facing away from the first side 20a, on the other hand, is disposed at the edge to the bottom 20d of the block 20 and serves for collecting and withdrawing the liquefied second medium S '.

For this purpose, a first pipeline 41a aligned with the second collector 22 extends from the second collector 22 which extends along the entire second side 20b along the extension direction E and which is connected to the second collector 22 via a connecting element 51 (also referred to as transition joint, see above) connected is. Here, the second collector 22 is preferably made of aluminum as the block 20, whereas the first pipe 41 a is preferably made of a steel. The first pipe 41 a is aligned with the second collector 22 and is through a

Through opening O of the shell 3 led out of the shell space M. The second collector 22 is hung with a free end 71 on one of the first pipe 41 a side facing away preferably in accordance with Figure 4 in a guide bearing 72 and secured there by means of a bolt 73. The guide bearing 72 is at a

Set inside 3a of the shell 3 and forms a (preferably U-shaped) upwardly open receptacle for the free end 72 of the second collector 22, which is closed at this end 72, so that the second medium S 'can not escape there.

Through the guide bearing 72 of the block 20 is positioned in the jacket or Kettle 3, wherein a movement of the second collector 22 along and around the

Extension direction E is possible. Transverse to the extension direction E, the guide bearing 72 prevents movement of the second collector 22, wherein falling out of the second collector 22 from the guide bearing 72 is prevented by the bolt 73, which together with the guide bearing 72, the free end 72 of the second collector 22nd encloses in a plane perpendicular to the direction of extension E. This guidance is an effective way to protect the block 20 against dynamic load cases, eg earthquakes.

Fig. 3 shows an alternative to the figures 1 and 2 embodiment of the second

Collector 22, wherein in contrast to Figures 1 and 2, the second collector 22 is not hooked with a free end 71 in a guide bearing 72, but rather against the extension direction E another first pipe 41 b from the second collector 22 goes off, in turn on a connecting element 51 is connected to the second collector 22 (the further first pipeline 41 b is again made of a steel in this case and the second collector 22 made of aluminum, see above) and counter to the extension direction E (ie opposite to the first pipeline 41 a) is led out of the jacket 3 of the heat exchanger 1. From the second collector 22 so the second medium S 'can thus be deducted from two sides or be fed in the reverse direction of flow from two sides into the second collector 22. The guide bearing 72 according to Figures 1 and 4 is thus replaced by a rigid bearing.

The heat exchanger 1 or block 20 according to the invention in the construction described above, as a result, advantageously allows a short kettle 3 and has further advantages in dynamic load cases (earthquakes). Especially for LNG (natural gas) applications, where the high pressures in conventional block-in-shell

Heat exchangers usually require multiple nozzles and manifolds, savings are possible. Thus, a manifold is completely saved and the comparatively smaller wall thickness of the spherical third collector 23 leads to material savings and reduces the weld volume. The smaller Kettle 3 also requires less coolant.

Preferably, for draining the block 20 additional drainage lines 61, 62 are provided which establish fluid communication between the third header 23 and the second header 22 and between the inlet ports 31, 32 and the second header 22. In FIG. 1, the drainage lines 61, 62 is shown in particular for the case that the third collector 23 is made of aluminum. In a third collector 23 made of steel, the drainage line 61 is preferably also made of steel and is preferably connected to the first pipe 41 a, the also preferably made of steel. The drainage line 62 is preferably made of aluminum in each case.

The first and the second collector 21, 22 have perpendicular to Erstreckunsgrichtung E preferably over an enclosure angle greater than 180 °, which causes a more favorable flow cross-section.

Furthermore, the spherical third collector 23 allows several ways of nozzle orientation. Furthermore, the flow in block 20 can advantageously be controlled by the use of a plurality of inlet ports 31, 32.

Figure 5 finally shows an alternative embodiment of the third collector 23, which could also be used in the embodiments according to figures 1 to 3. Here, the third collector 23 is designed as a hollow hemisphere, which preferably connects flush to the third pipe 44. The third pipe 44 may be welded to the circumference of the hemispherical third collector 23, wherein the second pipes 42, 43 as before depart from the third collector 23.
