Definitions

  • the invention relates to a heat exchanger according to the preamble of patent claim 1.
  • Such a heat exchanger is known from GB-A-2078361.
  • the header sections are welded together.
  • a disadvantage of the designs described is that, in the event of leaks, which can occur either as a result of incorrect manufacture or as a result of material fatigue, an expensive repair or even an exchange of the entire heat exchanger is often required.
  • a heat exchanger is known in which a manifold consisting of several segments with attached exchange plates is braced by an inner tube which is subjected to tension.
  • the known heat exchanger is a version to be used stationary for hot water heating systems, which is not suitable for special loads caused by inertial forces or extreme temperature differences.
  • the object of the invention is to improve a heat exchanger of the generic type in such a way that a simple and therefore inexpensive repair is possible in the event of leaks, without this being purchased with a significant impairment of the flow conditions in the header pipe.
  • the design and arrangement of the tension rods enables economical production and maintenance of the heat exchanger.
  • the solution according to the invention results in technical simplifications and thus cost reductions in the case of new production and in the repair of heat exchangers which have already been in operation and in which flawless elements can be reused.
  • a symmetrical prestressing of the collecting pipes can be achieved by the collecting pipes resting against the inner walls, the tension rods assuming approximately the temperature of the collecting pipe inner wall and thus thermal stresses remaining low. Furthermore, flow losses through components arranged inside the pipe are prevented. Two or more conditions can be distributed on the inner circumference of a header.
  • the tension rods are insulated from the interior of the header pipes. This is preferably done by providing shield plates and / or insulating layers attached to the tie rod. This further supports the desired effect of the same temperature of the collecting tube and the rods
  • tension rods are screwed from the outside to at least one of the header end sections. This enables simple and detachable bracing of the header pipes.
  • Means for setting a defined prestress on the tension rods are preferably provided, which can be designed as fitting pieces and have meanwhile been inserted into the header end sections and the ends of the tension rods. In this way, an uncomplicated and reproducible adjustable bracing of the heat exchanger can be achieved.
  • FIG. 1 shows a heat exchanger 1, the manifolds 2 and 3 of which consist of a plurality of manifold sections 5, 6 arranged one behind the other.
  • the manifolds 2 and 3 are connected to one another via a plurality of U-shaped profile tubes 21.
  • the mode of operation of the heat exchanger is as follows: A cool gas flow enters the collecting pipe 3 via openings in the collecting pipe section 12. The gas flow divides and flows through the plurality of U-shaped profile tubes embedded in the collecting tube 3 to the collecting tube 2.
  • the gas heats up due to the hot gas flowing in the cross-countercurrent in the direction indicated by 36.
  • the heated inner gas stream combines again in the collecting pipe 2 and flows off.
  • FIG. 2 shows a cross section through a header section 5, in which the tension rods 7 and 8 are arranged on opposite sides of the tube wall 22.
  • the pull rod 7 is shown in the sectional plane, while the pull rod 8 is shown with the fastening threaded bores 23 provided at the ends.
  • a number of profile tubes 21 are attached, which are sealingly connected to the tube wall 22 by means of welding or soldering.
  • guide shoulders 24, 25 are provided near the pipe ends, which prevent the tie rods 7, 8 from slipping sideways or twisting the header sections against one another.
  • the tension rods 7, 8 are provided with an insulating layer 10 and a shield plate 28 for the purpose of shielding the interior 9 of the header section 5.
  • Fig. 3 shows a tension rod 7 which bears against the inside of the tube wall 22.
  • Guide shoulders 24 are provided in the vicinity of the butt joints of manifold sections 5, 6, which prevent the tie rods or manifold sections 5, 6 from slipping sideways.
  • the tension rods 7 and 8 are machined to form parallel side surfaces 27, which enables simple mounting of the tension rods.
  • the tension rods 7 and 8 are fitted in such a way that the parallel side surfaces 27 lie at the level of the guide shoulders 24; the zone of the circular segments 30 can then be brought into engagement with the guide shoulders 24 by moving the tension rods 7, 8 in the longitudinal direction.
  • the end region 31 of the tension rod 7 is widespread, so that the tension rod 7 is supported when tension is applied via the shoulders 32 and the header sections 5, 6 are pressed against one another in a sealing manner.
  • two header pipe sections 5 and 6 are arranged one behind the other, the end of the header pipes being formed by the header pipe end section 11.
  • Two opposite tie rods 7 and 8 run along the inner wall of the collector tube 2, as a result of which they are provided at their ends opposite the collector tube end section 11 with fastening flanges and threaded bores 23 arranged therein, by means of which the tie rods 7 and 8 are clamped to the collector tube end section 11 by means of screws 34.
  • fitting pieces 13 are provided between the tension rods 7, 8 and the header end section 11.
  • the oval bores 35 provided for the introduction of the profiled tubes 21 in the collecting tube sections 5 and 6 are indicated in some areas in FIG. 4.
  • a construction of the collecting pipes 2 and 3 is preferably to be provided, in which the two ends of each tension rod 7, 8 are formed according to FIGS. 3 and 4, that is to say they are supported on the shoulders 32 at one end and at the other end with the collecting pipe end sections 11 and 12 are tense.
