Definitions

  • a heat exchange arrangement includes a heat exchange unit having a housing, a fluid inflow manifold tube and a fluid outflow manifold tu'be respectively arranged in an upper and lower portion of the housing, and a plurality of upright tubes connecting the inflow and outflow manifold tubes.
  • each of the manifold tubes consists of two hollow elongated shell sections having opposite ends and together constituting the respective manifold tube, these shell sections being formed intermediate their opposite ends with first projections extending transversely of the elongation of the shell sections and together constituting first tubular sockets to which the upright tubes are to be connected, and at their opposite ends with respective second projections together constituting second tubular sockets extending axially of the respective manifold tube and being laterally offset to one side of the longitudinal axis of the same to such an extent as to assure that a tubular component which is connected to the respective second sockets surrounding the same is substantiall flush with the manifold tube at the opposite side thereof from the one side.
  • the present invention relates to a heat exchange arrangement, and more particularly to a heating and cooling arrangement for air conditioning purposes.
  • Heat exchange arrangements of this type namely of the type utilizing manifold tubes and connecting tubes extending between the inflow and outflow manifold tubes, are known. They are, however, relatively expensive to manufacture and the necessity to provide lateral connections on the manifold tubes for the connecting nipples and other elements makes the width of assemblies consisting of manifold tubes and connecting tubes quite significant. Furthermore, such connecting nipples project laterally as already indicated, and make it impossible for the manifold tubes to be located closely adjacent the walls of the housing of the heat exchange arrangement, thus increasing the size requirements and reducing the effectiveness of the arrangement for heating and/or cooling purposes.
  • a more particular object of the invention is to provide a heat exchange arrangement comprising an assembly including inflow and outflow manifold tubes and connecting tubes, which assembly is simple and inexpensive to manufacture, requires relatively little space, and permits Patented June 23, 1970 positioning of the manifold tubes closely adjacent the walls of the housing.
  • a heat exchange unit comprising a housing having an upper and a lower portion, a fluid inflow manifold tube and a fluid outflow manifold tube each of which is arranged in one of these portions, and a plurality of upright tubes connecting the inflow and the outflow manifold tubes.
  • Each of the manifold tubes comprises, in accordance with the invention, two hollow elongated shell sections having opposite ends and together constituting one of the manifold tubes.
  • the shell sections are each formed intermediate their opposite ends with a plurality of first projections which extend transversely of the elongation of the shell sections and which together constitute first tubular sockets adapted for connection of the upright tubes thereto.
  • the shell sections are provided with respective second projections which together constitute second tubular sockets extending axially of the respective manifold tube and being laterally offset to one side of the longitudinal axis of the manifold tube to an extent which substantially corresponds to the wall thickness of a tubular component which is adapted to be connected to the respective second sockets surrounding the same.
  • tubular component is substantially flush with the respective manifold tube at the opposite side of the latter from the aforementioned one side and at this opposite side the manifold tube can be located closely adjacent to a housing wall or the like.
  • manifold tubes from two hollow shell sections greatly simplifies the manufacturing problems involved and therefore decreases the expense. Furthermore, it permits the production of manifold tubes having configurations which were heretofore not possible.

  • Louvre members 4 and 5 are secured to the assembly 3 at the opposite sides thereof.
  • the housing 2 is provided with an inlet 21 in the bottom wall thereof and with an outlet 22.
  • the flow of air into the housing 2 is indicated with the arrow A, and it will be seen that in the housing the air flows through the assembly 3, guided by the louvre members 4 and 5, in the direction of the arrows B to thereupon leave the housing in the direction of the arrow C through the outlet 22.
  • the top wall of the housing is identified with reference numeral 23.
  • the entire unit may be secured or simply placed against a wall 24 with its housing side wall 2" while the other housing side wall 2" remains exposed.
  • FIG. 11 will be discussed in more detail subsequently it is already pointed out that instead of a completely enclosed housing, which is merely provided with an inlet and an outlet, the housing may also have an open side, that is one of the side walls 2 or 2" may be missing, and the assembly 3 itself will in effect replace the missing side wall. This is shown in FIG. 11.
  • the assembly 3 consists of two manifold tubes 6 and 7 which are respectively arranged in the upper and the lower portion of the housing, with the manifold tube 6 being located closely adjacent the sidewall 2" and the manifold tube 7 being located closely adjacent the sidewall 2.
  • the manifold tubes serve for inflow and outflow of heat exchange fluid, that is heated or cooled fluid, and they are connected in a manner which will be discussed presently by a plurality of upright tubes 8 which, as is more clearly seen in FIGS. 2-4, extend substantially normal to the elongation of the respective manifold tubes and extend in sub stantial parallelism with one another.
  • the manifold tubes 6 and 7 each consist of two hollow shell sections 9 and 10 which are provided intermediate their opposite ends with tubular projections 12 constituting tubular sockets to which the upright tubes 8 are connected, for instance by welded seams as illustrated in FIG. 2 where the seams are designated with reference numeral 13.
  • the sections 9 and 10 are different from one another in that it is only the section 10 which is provided with the tubular projections 12.
  • both sections 9 and 10 are provided with additional projections which together constitute tubular sockets 11 (one shown).
  • the tubular sockets 11 are provided with screw threads 14 so that connecting nipples 50 or analogous elements may be threadedly secured thereto as shown in FIG. 4.
  • FIGS. 3 and 4 show that the sections which are here identified with reference numerals 9a and 10a, may also be constructed so as to abut one another in a substantially vertical plane of separation.
  • the welded seam is here identified with reference numeral 15a.
  • FIG. 3 The cross-sectional configuration of the main body portions of the manifold tubes constructed in this manner, that is the body portions other than the tubular sockets 11, is most clearly shown in FIG. 3 where it will be seen that it may be of substantially rectangular outline, although it may of course be of other outline such as oval, generally polygonal or the like.
  • tubular sockets 11 are laterally offset to one side of the axis of the respective manifold tube 6 or 7. This is most clearly shown in FIGS. 3 and 4 and the offsetting is of such magnitude as to correspond substantially to the well thickness of a connecting nipple 50or other member, such as an additional tubewhich is to be secured to the respective tubular socket '11 surrounding the same externally.
  • the purpose is to assure that, as seen in FIG. 4, such nipple 50 or similar component is substantially flush with the outermost line 10' (compare FIG. 4) of the respective manifold tube that is flush on that side which is opposite the side towards which the tubular sockets 1,1 are offset. This makes it possible, as shown clearly in FIG.
  • the sheet-like louvre members 4 and 5 can be readily secured, for instance by spot welding, to the surface facets 9", l0", and these facets 9", (10" provide a proper abutment and support for the louvre member 4, 5 while at the same time making it possible for the latter to be in contact with the upright tubes 8 over the entire height of the latter so that a direct heat exchange takes place between the tubes 8 and the louvre members 4, 5.
  • the latter incidentally, are provided with inclined guide portions 16, 17 and with air openings 16', 17', respectively, associated with these guide portions 16, 17 in such a manner that the guide portions 16 are inclined upwardly towards the outlet 22 whereas the guide portions 17 are inclined downwardly towards the inlet 21 to thereby guide air coming from the inlet 21 into the air openings 17, from the same to and outwardly beyond the air openings 16' and thence to the outlet 22.
  • This is particularly clearly shown in FIG. 11.
  • FIG. 5 a plurality of the heat exchange units which have been diagrammatically illustrated in FIG. 1 may be connected into a composite unit 100.
  • the construction of the individual units, here identified with reference numerals 1, 1', 1.” and 1", is similar to that discussed in the description of FIGS. 1-4 and it will be appreciated that the individual manifold tubes 6 and 7 of the respective units are connected to one another.
  • Such assembly of different units into a composite unit makes it possible to accommodate the size and heat exchange capabilities of the composite unit precisely to the area wherein air is to be conditioned.
  • the individual houslngs of the various units 1-1 are identified with reference numeral 2 and abut one another, being connected by screws, bolts, or in other suitable manner.
  • the incoming heat exchange medium passes in the direction of the arrow F through the manifold tube 7.
  • it could be introduced through the manifold tube 6 instead although, if, for example, hot water is involved, the convection phenomenon will provide for circulation of the same in the tubes 8, if the water is introduced through tube 7 and a weaker pump can be utilized under the circumstances than would be possible otherwise.
  • FIG. 6 is of upright tubes 8 associated with'unit 1 closest to the heat-exchange fluid inlet
  • FIG. 7 is of similar tubes which are, however, used in the unit 1'. It is clearly shown that in FIG. 6 the upright tubes 8 are provided with three of the constrictions 18 whereas in FIG. 7 they are provided with only two of these constrictions.
  • FIG. 8 which shows the upright tubes 8 of the unit 1"
  • each of the tubes 8 has only one of the constrictions 18 whereas in FIG. 9 the tubes 8 of the unit 1 have no constrictions whatsoever and thus correspond to the embodiment illustrated in FIGS. 2 and 3, for instance.
  • the difference in fiow resistance is of course obvious and need not be further explained. As shown in FIGS.
  • FIG. 18 corresponds to the showing of FIG. 6, FIG. 13 to that of FIG. 7, FIG. 14 to the showng of FIG. 8 and FIG. 15 to the showing of FIG. 9.
  • FIGS. 12-15 as opposed to those labeled as FIGS. 69 is that in FIGS. 1215 the upright tubes 8 are of constant cross section in all units, and that the different flow resistance is obtained by introducing sleeve-shaped inserts 25 into the tubular sockets 12. This is advantageously accomplished before the two shell sections 9a, 10a are secured to one another, and it will be seen that in FIG.
  • the opening in the insert 25, identified with reference numeral 26, has a smallest cross-sectional area, that in 'FIG. 13 the opening 26 has a somewhat larger cross-sectional area, that in FIG. 14 the opening 26 has a still larger cross-sectional area and that in FIG. 15 the insert is omitted.
  • FIG. 16 The embodiment illustrated in FIG. 16 is largely similar to that shown in FIG. 1. As mentioned before, identical reference numerals identify identical components. In FIG. 16, however, the airflow is identified with arrows and with the letters A1, B1 and C1. In this embodiment and air circulating means 27, which advantageously is in form of a well known blower, is secured to the housing side wall by means of a bracket or similar expedient 49 and is arranged above and closely adjacent to the air inlet 21. As in the embodiment of FIG. 1, the outlet 22 is again located at the opposite side of the assembly 3 from the air inlet 21.
  • air circulating means 27 which advantageously is in form of a well known blower
  • FIG. 17 differs from FIG. 16 in that the assembly 3 is not inclined but rather is vertical and replaces one side wall of the housing 2. This has already been discussed with reference to FIG. 11. A further difference is that in FIG. 17 there is no specific air inlet at the bottom of the housing 2. There is, however, the air outlet 22 and the air circulating means 27 is arranged in the housing closely inwardly of the air outlet 22 so that air is aspirated through the assembly 3 by operation of the air circulating means 27 and will then issue from the outlet 22.
  • FIGS. 16 and 17 can be provided for heating purposes as well as for cooling purposes. It will be noted that in FIGS. 16 and 17 the arrows indicating the air flow are double-headed, to indicate that the air flow may be in opposite directions, depending upon the operation of the air circulating means 27, it being clear that if cooling is to be effected, the air circulating means 27 is made to aspirate air through the outlet 22 from the room whose air is to be conditioned.
  • FIG. 18 it will be seen that here there is shown a diagram illustrating how a heat exchange arrangement may be installed. It is assumed that a plurality of composite heat exchange units are provided, corresponding to those shown in FIG. 5, and a further plurality of composite heat exchange units 100 are also provided. The ones identified with reference numeral 100' are assumed to be capable of both cooling and heating functions and it will be appreciated that neither the units 100 nor the units 100' need be of identical size and heat exchanging capacity, as is suggested ni FIG. 18, but may be different from what is illustrated in this figure.
