Abstract
A heat exchanger comprises a jacket tube (1), housing rings (2, 2a) and covers (6, 6a) at each end of the housing rings. Tie rods (13) hold the parts which form the housing together. A tube nest (15) is connected to two tube plates (17, 17a) within the housing. Inside each cover are a number of parallel grooves (9 to 9c) for the engagement of a partition wall (21) which is connectable to the tube plate. In use, a first heat exchange medium flows from inlet (10) through tubes (16) on the right of partition wall (21) and thence returns through tubes (16) on the left of the partition to outlet (11). A second medium flows from inlet (4) over the tubes to outlet (4a). The tube plates may slide inside the housing to accommodate thermal expansion. <IMAGE>
Description
SPECIFICATION
Heat exchangers
The invention relates to heat exchangers.
In a known heat exchanger comprising a housing composed of a jacket tube, housing rings and covers coaxially arranged at each end of the jacket tube, the covers being provided at the free ends of the housing rings and the housing rings and covers being substantially identical in design, and fastening means holding together the parts which form the housing, and a guiding unit provided within the housing, movable within the scope of its thermal expansion separating the heat-exchanging media, the guiding unit being composed of two tube plates and a tube nest therebetween and connected thereto, the tube plates being designed as pistons slidable inside the housing, the jacket and tube and the housing rings are provided with fastening flanges at their ends and the cover, which has a central connection, has a fastening flange on its edge that is directed away from the connection.The production of parts provided with flanges is expensive, and special fastening means are necessary for every two flanges which are to be connected together. Such a heat exchanger design is relatively costly (DE AS 11 34 397).
It is an object of the present invention to provide a heat exchanger which is composed of simple parts which require minimal machining and which can be used for many applications without extensive modifications.
According to the present invention, the heat exchanger as aforesaid is characterised in that the jacket tube consists of a standard tube which is constant in thickness and at each end of which there is provided a necking which has a shoulder for supporting the adjacent housing ring, and in that each housing ring has on its circumference a number of bosses for the provision of connections for the supply or the removal of a heat-exchanging medium; one of the bosses being provided for a connecting bore: and in that at the side of the cover that is directed towards the housing interior there is provided a number of parallel grooves for the engagement of a partition wall which is connectable to the tube plate, and in that several connections can be provided in the cover, beyond the ribs, and in that the fastening means are designed as the rods which are provided at regular intervals on the circumference.
Thus, the parts forming the heat exchanger are simple in design and can therefore be manufactured at low cost. Only few cutting operations are necessary for the assembly of a specific heat exchanger. Welding operations are completely dispensed with. Due to tie bolts being used as the fastening means, the number of fastening means required is considerably reduced so that the heat exchanger according to the invention can be assembled without a high expenditure. Starting out from such a heat exchanger, it is possible to manufacture heat exchangers for various applications with few additional operations and by using only few parts.
A completed heat exchanger can be easily and quickly converted from a different application. It can be easily dismantled and subsequently reassembled for the purpose of cleaning or repair.
Thus, it is possible to change a single-pass heat exchanger in a simple manner into a multi-pass and at least a two-pass heat exchanger.
A two-pass heat exchanger having a partition wall which has been welded on at the side that is directed away from the tube nest and which engages in a groove in the adjacent cover is known from US PS 2 237 029. However, the tube plate thereof is not movable relative to the cover.
In a heat exchanger constructed in accordance with the present invention unloading of the jacket tube is possible.
Further advantages will emerge from the description and the drawing, in which a two-pass heat exchanger is diagrammatically shqwn as an exemplified embodiment of the subject matte.r of the invention in a partial longitudinal section,
A jacket tube 1, which is arranged in the centre of the heat exchanger, consists òf a standard tube, at the ends of which there are provided cuts forming outwardly projecting shoulders. These - cuts serve for receiving housing rings 2, and.2'a respectively; The housing rings 2, 2a have bosses 3 which are arranged at regular intervals on the circumference thereof and which are provided for the establishment of connections.In the exemplified embodiment shown, the housing rings 2 and 2a have connections 4 and 4a respectively.
The gaps between the external circumference of the jacket tube 1 and the internal circumference of the associated housing rings 2 and 2a are sealed with the aid of sealing rings 5 and 5a respectivey which are arranged inside the housin'g'?ihgs.
At the ends of the housing rings 2 and 2a which are directed away from the jacket tube 1, therie are arranged covers 6 and 6a respectively. The housing rings 2, 2a and the covers 6, 6a are substantially identical in design; Thecovers 6, 6a have circumferential edges 7 and 7a respectively and five inwardly projecting
ribs 8, 8a, 8b, 8c and 8d which vary in width and between which there are provided grooves 9, 9a, 9b, 9c respectively. The central narrowest rib.8b extends diagonally. The two ribs 8a and 8c
adjacent thereto are wider than-the two external
ribs 8 and 8d. However, the grooves 9, 9a, 9b, 9c are identical and are each designed so as to widen
in a wedge-like manner towards the outside in
cross section and to have a bottom of identical
width.The ribs 8 to 8d also extend on the edge of the cover. In the central zones beyond the ribs 8
and 8d, there are provided eyes for the provision
of admission bores. An admission bore 10 is
provided in one of the eyes and a drain bore 11,
which is shown in broken lines, is provided in the
other eye on the opposite side. The cover 6a is
designed without admission and drain bores. The
possible provision of a drain bore 1 a is shown in
dash-dotted lines.
The covers 6, 6a have radially projecting flange
parts 1 2 and 1 2a respectively, in which there are
provided through holes for the reception of tie
rods 13. In the exemplified embodiment shown,
there are provided at regular intervals on the
circumference four flange parts 12 aid 1 2a in the
covers 6 and 6a respectively and four tie rods 13,
onto the ends of which nuts 14 and 1 4a respectively have been screwed.The housing,
which is formed by the jacket tube 1, the two
housing rings 2, 2a and the two covers 6, 6a is
held together by the tie rods 1 3. In order to unload
the jacket tube 1 , the tie rods may each be
provided with a shoulder in the zone of the ends of the jacket tube 1 , on which shoulder the associated housing ring 2 or 2a is supported. For this purpose, this ring has corresponding through bores or grooves, which are provided between
longitudinal ribs, for the reception of the tie rods 13. By this means, the jacket tube 1 can be unloaded.
In the interior of the housing, there is provided e guiding unit for the heat-exchanging media. This guiding unit is formed by a tube nest 1 5, the tubes 1 6 of which are each fixedly connected to tube plates 1 7 and 1 7a respectively at the ends. The tube plates 17 and 1 7a are cup-shaped in design and have circumferential edges 1 8 and 1 8a respectively. The gap between the circumferential edge 1 8 and the housing ring 2 is sealed by means of a sealing ring 1 9 and the gap between the circumferential edge 18 and the edge 7 of the cover 6 is sealed by means of a sealing ring 20.
Sealing rings 1 9a and 20a seal in the same manner the gap between the edge 1 8a of the tube plate 1 7a on the one side and the gap between the housing ring 2a and the edge 7a of the cover 6a on the other side. The guiding unit is capable of axial movement inside the housing of the heat exchanger in accordance with its thermal expansion.
At the side of the tube plate 17 that is directed away from the tube nest 1 7 and on the edge 18 thereof, there is secured a partition wall 21 which, at the end that is directed away from the tube plate 17, carries a strip 22 which is located in the groove 9b, into which the partition wall 21 also partly projects. The partition wall 21 lies somewhat beyond the centre of the tube plate 1 7 and may partly cover a tube mouth or several tube mouths of the tube bundle 15, which does not however impair the effectiveness of the heat exchanger.
The exemplified embodiment is a two-pass heat exchanger, into the admission bore 10 of which the first heat exchanger medium is fed in the direction of the arrow A, which medium flows along the tubes provided to the right of the partition wall 21 in the drawing in the direction of the cover 6a, is deflected there, then flows upwardly on the left-hand side in the drawing and emerges in the direction of the arrow B from the outlet bore 11 shown in broken lines.
If the partition wall 21 and the sealing strip 22 are not provided, then only the admission bore 10 is provided in the cover 6 and the outlet bore 1 la,
shown in dash-dotted lines, is provided in the
cover 6a. In this case, the two covers 6, 6a are
entirely identical in design. The heat exchanger
medium brought in through the admission bore 10
then flows only in the direction of the outlet bore
11 a and does not flow in the opposite direction,
too.
By increasing the number of partition walls 21
it is possible to manufacture multi-pass heat
exchangers, provision then having to be made in
the covers 6 and 6a for the necessary admission
and drain bores.
The second heat exchanger medium is fed into
the heat exchanger through the connection 4 and
leaves the exchanger through the connection 4a.
The afore-described heat exchanger has been
assembled from individual parts in the manner of a
unit construction system. It can be modified in a
simple manner; for example, by rotating one of the
housing rings 2, 2a about its axis at least one of
the connections is steplessly adjustable, thus
allowing the heat exchanger to be adapted to
different installation conditions.
