Definitions

  • the invention relates to a heat exchanger with a plurality of tubes, which are arranged coaxially with one another and with a mutual radial spacing, made of sleeve-conducting material for the heat exchange between at least two media guided in the spaces formed between the tubes, with a connection for the media and terminal support for the pipes, this pinching between se, whereby splitter heads are provided with which coupled the pipes end-hand media-tight manner and are axially braced 'and the spaces between the tubes to the terminal connections wei ⁇ terlei end., distributed concentrically arranged intermediate show rooms.
  • Such a heat exchanger is known from DE-A-27 48 183.
  • the distributor heads taper in the direction of their end facing the tube bundle and, in the process, form terraced seating surfaces on which the tubes are fitted with sealing rings with intermediate supports and are brought into contact with AxiaT stops against the distribution heads.
  • the distributor heads form two diametrically opposed, crescent-shaped collecting spaces, which are connected via suitable radial bores to the intermediate space to be connected in each case between two adjacent tubes of the tube bundle.
  • the crescent-shaped collecting spaces merge into two adjacent connecting pieces for the two media to be brought into mutual heat exchange.
  • the axial bracing of the tube bundle between the two terminal distributors 1 is carried out by means of a tensioning rod that runs centrally through the innermost tube and connects the two distributor heads.
  • This known construction includes the necessity that the tubes of the tube bundle decrease in length from the outside inwards, so that they can only be grasped and pulled apart with difficulty when the heat exchanger is dismantled, for cleaning purposes, for example.
  • the design of the distributor heads provides a final definition, so that there is no possibility of using such a heat exchanger of the known type. known type, for example, for different applications that require different flow cross sections.
  • the necessity of holding together the known heat exchanger by means of a central tension rod thus requires an additional, ateri al complex and heavy component 1.
  • a very considerable disadvantage of the known construction is, however, that the media to be brought into heat exchange in the distributor 1 have to be guided through diametrically opposite and thus completely separate collection spaces, so that the distributor spaces with regard to the heat exchange are entirely fail, which in this respect results in a considerable loss of space and material.
  • the opposing arrangement of the collecting spaces also leads to a gradual distribution of the medium over the entire heat exchange space occurring at the transition from the respective collecting space to the subsequent heat exchange, which extends over an entire circular cross-section, so that at the end of such a space Heat exchange space is a practically non-flowed and therefore flowally dead area within which solids entrained by the medium can accumulate and compress, which is further promoted by the fact that the respective heat exchange space with the said collection space only has one or a few radai that are constricted in cross section 1 holes in the distributor head is connected. There is thus a risk or even a probability that the tubes of the tube bundle will become compressed due to solid materials compressed between their ends after prolonged operation.
  • the object of the invention is therefore to design a heat exchanger of the type mentioned at the outset in such a way that the distributor heads, in a manner comparable to the tube bundles, also make a full contribution to the heat exchange performance, already in the distributor head a distribution taking place over the entire circumference of the heat exchanger the media is guaranteed without a blind spot, complex and space-consuming clamping devices for holding the tube bundle between the two distributor heads are eliminated and finally, while largely maintaining existing components, a simple conversion to different flow cross-sections is possible.

  • This embodiment of a distributor head according to the invention first of all provides for the media flow in the circumferential direction practically uninterrupted flow cross sections between the outer and inner wall on the one hand, inner wall and sleeve on the other hand and finally inside the sleeve, so that the entire distributor head can already be fully effective as a heat exchanger without there being blind spots for the media flow, since the media are also 'distributed in the distribution head directly over the entire circumference.
  • the Verte 1erkopf is made of heat-conducting material, but it can also be made of glass, for example.
  • the tube bundle with the distributor head is clamped in an extremely simple manner via the connection between the outer wall and the outer tube of the tube bundle, since this connection simultaneously presses the second tube and the sleeve against the axial stops of the inner wall of the distributor head and thus sit tight.
  • This design also leads to the fact that the length of the individual tube elements of the tube bundle increases from the outside to the inside, so that the individual tube ends are easily grasped when the distributor head is removed and the tubes can be pulled apart.
  • this third tube is designed as a set in the manner of an interchangeable cartridge, so that different cross-sections of the third tube can be used alternately, if only the size of the connection connection of the sleeve, without great difficulty is retained at its seat against the axial wall of the inner wall.
  • the flow cross-section between the inner, third tube and second tube can thus be varied without difficulty and thus adapted with slightly different requirements, the remaining parts of the heat exchanger being able to be used again.
  • the inner cross-section of the inner, third tube can be designed differently by different internals, in particular with regard to the training the flow inside the third tube and the stabilization or stiffening of the cross section of the inner, third tube.
  • a distributor head of the type according to the invention can be very easily subjected to an X-ray examination, since the annular space between the outer and inner walls is easily accessible, for example for inserting an X-ray film. In this way, faulty distributor heads can be eliminated with little effort and the later occurrence of defects with often unpleasant and costly consequences can be avoided.

Abstract

Un échangeur de chaleur comporte plusieurs tubes (1, 2, 3, 4) agencés coaxialement et des têtes de répartition (8, 45) qui serrent entre elles ces tubes, maintenant leurs extrémités et assurant un raccordement avec les milieux d'échange de chaleur. Ces têtes de distribution permettent le couplage à étanchéité du côté frontaal des tubes (1, 2, 3, 4) avec les milieux d'échange ainsi que leur serrage axial. Chaque tête de distribution (8, 45) présente deux parois concentriques (9, 10, 46, 47) et une chambre frontale (17, 50) renfermant l'espace annulaire (11, 48, 49) formé entre ces parois. La paroi extérieure (9, 46) est reliée au tube extérieur (1), et le deuxième tube (2) à l'intérieur du tube extérieur (1) est introduit dans la paroi intérieure (10, 47) contre une butée axiale (24). De plus, le tube (3) agencé à l'intérieur du deuxième tube (2) est serré contre une butée axiale (28) de la paroi intérieure (10, 47) sur la face intérieure de la chambre frontale (17, 50) par l'intermédiaire d'un manchon (26, 58, 59) relié à son extrémité. L'intérieur (34) du manchon (26) communique avec la chambre frontale (17, 50) par une ouverture (19, 55). Un raccordement entre un premier milieu d'échange et l'espace annulaire situé entre la paroi intérieure (10, 47) et le manchon (26) est assuré par l'intermédiaire d'une section de sortie radiale (15) de la tête de distribution (8, 45), tandis qu'un raccordement avec un autre milieu d'échange de chaleur est assuré par l'intermédiaire d'une ouverture (18) de la chambre frontale (17, 50).
