United States Patent 3,346,043 HEAT EXCHANGER PIPE COIL WITH SUPPORT MEANS Ernst Thurnauer, Winterthur, Switzerland, assignor to Sulzer Brothers Limited, Winterthur, Switzerland, a corporation of Switzerland Filed Aug. 26, 1965, Ser. No. 482,705 Claims priority, application Switzerland, Sept. 3, 1964, 11,472/ 64 8 Claims. (Cl. 165-162) The invention relates to a heat exchanger having adjacent flat pipe coils which comprise straight portions joined by bends and are held in longitudinal bearer members running perpendicularly to the straight portions near the bends, the longitudinal members combining to form a wall, which heat exchanger is characterized in that the longitudinal members and pipe coils are arranged vertically and have lateral arms directed towards the heat exchanger wall for mounting them in holders on this wall.
It is known that horizontally arranged pipe coils can be attached by means of flat longitudinal bearer members which have semicircular cuts for the pipes, form a continuous wall and are supported on the masonry of a vapor generator. However, this design can only be used where the pipe coils are not very large. In particular, it cannot be used for heat exchangers in nuclear reactor installations, where the special temperature conditions entail large heat exchange surfaces and therefore large-size pipe coils.
The invention will now be described with reference to an embodiment shown diagrammatically in the drawings. In these:
FIG. 1 shows a section through a heat exchanger according to the invention parallel to the planes of the pipe coils;
FIG. 2 shows a section taken along a line II-II in FIG. 1; and
FIG. 3 shows a view corresponding to FIG. 1 of a heat exchanger with staggered pipe coils.
In FIG. 1 a preferably rectangular duct formed by side walls 1 contains two pipe coils 2, 3. These coils consist in a known manner of straight portions of pipe a connected by bends b. The coils 2, 3 shown in FIG. 1 are arranged in one plane, and each has a straight distance piece 0 with bends d after every few windings. This distance piece forms a space within which a few windings of the other pipe coil are arranged. At the ends of the straight parts a, near the bends b, d, the coils are mounted in longitudinal bearer members 4. These members 4 are made of rolled stock with a T-profile, in the flange of which semicircular recesses corresponding to the diameter of the pipes are cut. The width of the flange with the recesses and the distance between the individual pipe coils are so selected that the flanges of adjacent longitudinal members touch and so form a wall. The members 4 have arms 5, 6 directed towards the walls 1 and serving to attach the members 4 to the walls 1. The arms have welded struts 7 and are therefore relatively rigid. The arms 6, which like the arms 5 are made of sheetmetal or another flat material, have two- part struts 8, 10 joined by bolts 11. When the bolts 11 are pulled out the arms 6 are relatively soft compared with the arms 5, and they can be slightly bent during assembly. The holes for the bolts 11 in the parts 8, 10 are preferably staggered so that the arms 6 are bent slightly upwards in the drawing by the insertion of the bolts 11. For this purpose the bolts 11 may, for example, be conical or have conical ends. The arms are fixed by driving in the bolts and support themselves accordingly against their mounts in the wall 1. These mounts are formed in this embodiment by angle pieces 12, 13 running along the wall 1 transversely relatively to the planes of the pipe coils, which they support. Some of the angle pieces, e.g. the pieces 13 on one side, preferably have a recess 14 engaged by a projection 15 on the arm 5 or 6. By this means the longitudinal members and also the coils are fixed on one side. With this arrangement it is also an advantage to join the pipe coils to the longitudinal members by welds 16 in some places.
FIG. 2 shows a plan of a heat exchanger according to the invention, taken along a line IIII in FIG. 1. At the top of this figure there are two pipe coils in the final position after assembly, whereas at the bottom there is one pipe coil in a position during assembly, before the coil is pushed up to those already assembled so that the flanges of the members 4 touch and form a wall. The widths of the arms 5, 6 are selected so that these also touch when assembled to form a continuous wall. The longitudinal members may also have lateral baflies 17 between the pipe bearers, covering part of a cross-section belonging to the pipe coil between the longitudinal bearer and the wall 1. These featuresthe formation of a continuous wall by the flanges of the members 4, the arms 5, 6 and the arrangement of the baffies 17serve to throttle the flow along the pipe bends of the medium surrounding the coils during operation ofthe' heat exchanger. The reason for this is that the straight portions a of the pipes are normally provided with fins, which not only improves heat transmission but also increases the resistance to flow of the medium flowing round the pipes so that a short circuit may form along the pipe bends. If this short circuit is prevented, better use is made of the heat exchange surface. The gas which gives off heat reaches the outlet from the heat exchanger with an even temperature distribution over its cross-section, because there is no component flow taking less part in the exchange of heat. This has advantages as regards thermodynamics. It is not necessary or desirable to have a perfect seal, since if a small portion of the medium can flow past the pipe bends, the pipe bends can also take part in the exchange of heat, which would not be the case if the seal were perfect.
FIG. 3 shows an arrangement corresponding generally to FIG. 1 but with the pipe coils in adjacent planes staggered relative to each other. For this reason the semicircular recesses in the longitudinal members are staggered relative to each other on each side of the flange. The arrangement is substantially the same as in FIG. 1. The straight portions a of the pipe coils may be provided in a known manner with flat and helical fins 20, 21, as shown in the lower portion of FIG. 3.
The heat exchanger constructed according to the invention has the advantage over known heat exchangers that the heat exchange pipes are easier to assemble and to produce, while the heat exchange properties are in part even better. The pipe coils between the straight portions 0 can easily be produced in short sections in the workshop. The individual coils are then provided with the longitudinal members 4 and can be welded together at seams 22 before or after assembly, depending on the size of the heat exchanger. Thus the pipe coils are easily made. Assembly is carried out by pushing the pipe coils with the longitudinal members sideways into the mounts 12, the bolts 11 being drawn out. The coils and longitudinal members are fixed by driving in the bolts. The seams in the straight parts 0 are easy to weld as the pipes are straight and are accessible even after assembly, if necessary, e.g. through windows in the wall 1.
There is no reason why the longitudinal members should not be in one piece on each side of the pipe coils. However, this division of each longitudinal member into a number of bearer portions, as in the preferred embodi ments, increases the resilience and flexibility of the arrangement, properties which encourage compensation of inaccuracies occurring during assembly and also allow heat expansion to take place. This flexibility is further increased by the staggered arrangement of the bearer portions.
