Definitions

  • the invention relates to a heat exchanger comprising tubular members fixed with its ends.
  • tubular members usually formed by round tubes in conventional heat exchangers are fixed with their ends in so-called tube plates which have to be made to size for every heat exchanger.
  • NL-A-6 903 607 discloses a heat exchanger in which the ends of the tubes are clamped between frame-like parts placed one on top of the other, in which a semicircular recess has been formed in each of the frame-like parts in such manner that two of these recesses constitute a hole for receiving one end of a tube.
  • each of the tubular members comprises at each end a sleeve which is slid on the tubular member in question and which has an at least substantially rectangular cross-section and on its outside comprises a circumferential groove for receiving a gasket, the sleeves of the tubular members forming part of the heat exchanger being clamped in a frame surrounding the sleeves.
  • the tubular members When using the construction according to the invention the tubular members may be constructed in any desired length and be provided at their ends with sleeves of equal construction.
  • the sleeves which have a rectangular cross-section of tubular members forming part of the heat exchanger can be arranged in an rectangular pattern beside and above each other and then be clamped in a simple manner, and by using the construction according to the invention heat exchangers of any desired size can thus be built while using a small number of standard components.
  • Extruded profiled members in particular profiled members manufactured from synthetic resin, may advantageously be used for the tubular members.
  • High-grade thermoplastic synthetic resins for example, aromatic polycarbonate, modified polyphenylene ether, polybutylene terephtalate and polyetherimides are preferably used as synthetic resin materials.
  • tubular members 1 are used for constructing a heat exchanger formed by tubes which are formed from two parallel extending walls 2 and 3 which are connected at their ends by semicircular connectors 4 and 5.
  • the height of a tube is a multiple of the width of the said tube.
  • Such tubes can simply be extruded in any desired length from a suitable synthetic resin or a suitable metal and, if desired after extrusion, be cut to the desired lengths.
  • a sleeve 7 ( Figure 2) is slid on each end of the tube.
  • Said sleeve comprises a passage 8 which is adapted to the interior passage of the tube 1 and which has a stepped shape in such manner that, viewed in Figure 2, said passage, in the righthand end portion of the sleeve 7, has a cross-section which is suitable for receiving with a force fit the end of a tube 1, while the remaining part of the passage 8 has a slightly smaller cross-section so that in the interior of the sleeve a shoulder (not further shown) is formed at the transition between the parts of the passage 8 having different sizes, against which shoulder the end of the tube 1 will engage when inserting said end of the tube 1 into the sleeve 7.
  • a suitable adhesive may be used to obtain a rigid and tight connection between the sleeve 7 and the end of the tube 1.
  • the sleeve 7 also comprises a circumferential groove 9 provided in the outer circumference. This groove is destined to receive a correspondingly shaped gasket 10 shown in Figure 3 and manufactured from a suitable elastic material.
  • grooves 11 are provided, while the oppositely located side comprises complementary projections 12.
  • grooves 13 adjoining the projections 12 are provided in the upper short end wall of the sleeve 7, while viewed in Figure 2 complementary projections 14 are provided in the lower short side wall.
  • the sleeves may be manufactured by injection moulding. They are preferably manufactured from high-grade thermoplastic synthetic resins as mentioned hereinbefore.
  • Figure 4 shows a plate-shaped member 15 which throughout its surface comprises on each side regularly divided studs 16 only a few of which are shown in Figure 4.
  • the studs provided in a first row extending at right angles to the longitudinal direction of the plate-shape member are staggered with respect to the studs in the row situated therebehind.
  • profiled, hollow beams 17 substantially rectangular in cross-section as shown in Figure 5 may be used.
  • the beam at its one wide rectangular side is provided, by way of example, with three grooves 18, 19 and 20 extending in the longitudinal direction of the beam 17, while on the oppositely located rectangular side opposite to the grooves 18 and 20, ribs 21 and 22 extending in the longitudinal direction of the beam are provided, while centrally between said ribs a groove 23 is present.
  • Such a profiled beam 17 can also be manufactured efficaciously by extrusion from a suitable synthetic resin or a suitable metal or the like.
  • an L-shaped connector 24 as shown in Figure 6 may efficaciously be used. Holes 25 and 26, respectively, extending in the longitudinal direction of the two limbs of said L-shaped connector are provided in the two limbs in such manner that the holes 25 present in one limb do not intersect the holes 26 present in the other limb. The function of the holes 25 and 26 will be explained in detail hereinafter.
  • plate-shaped members 15 may be inserted into the tubular members 1 so that on the one hand the fluid passed through the tubular members will flow closer along the walls of the tubular members, while a zig-zag flow of the fluid in the tubular members will be generated by means of the studs 16 provided on the plate-shaped members 15, said flow also promoting the heat transfer.
  • tubular members may be provided beside and above each other and plate-shaped parts 27 may be provided between two columns of tubular members placed above each other, said parts, although not further shown in Figure 7, comprising studs on each side similarly to the plate-shaped members 15.
  • a good guiding of the fluid bypassing the tubular members along said tubular members in a zig-zag-like path of flow is also effected by means of such plate-shaped members.
  • An at least substantially rectangular assembly of sleeves thus obtained and situated beside and above each other may then be combined to form a firm unit while using profiled beams 17 the ends of which will preferably have been mitre sawn.
  • the limbs of an L-shaped connector 24 are inserted and the assembly may then be firmly connected together by means of clamping bolts which are passed through holes formed in the boundary walls of the profiled beams 17 and situated in the elongation of the holes 25 and 26, respectively, said clamping bolts extending through the hollow profiled beams 17 from one side of the assembly to the oppositely located side.
  • the arrangement is such that, as is also shown in Figure 8, on certain sides of the assembly formed by the sleeves the projecting parts 21 and 22 engage in recesses 11 or 13 of sleeves 7 placed above or beside each other which recesses are situated in the elongation of each other while on other sides the projecting parts 12 or 14 of the sleeves are incorporated in recesses 18 and 20 of the profiled beams. It will be obvious that in this manner a firm connection is obtained between the sleeves mutually and between the sleeves and the frame formed by the profiled beams 17 and surrounding the sleeves, the tubular members being effectively locked against movement in the longitudinal direction.
  • channel connectors 28 and 29 may be connected to a heat exchanger thus obtained for the inlet and outlet, respectively, of a first medium to be passed through the tubular members, while further connectors 30 and 31 can be connected to the heat exchanger for the inlet and outlet, respectively, of a second fluid which bypasses the tubular members to thus produce an exchange of heat between the first and the second fluid.
  • the remaining side walls of the heat exchanger are closed by means of cover plates 32.
  • a heat exchanger can be built up having any desired number of tubular members which may be constructed in any desired length.
