Definitions

  • Our present invention relates to a heat exchanger in which two fluids of initially different temperatures pass in close proximity to each other, but along different paths, for the purpose of heating or cooling one of the fluids at the expense of the other.
  • a typical field of application of such heat exchangers is in the cooling of lubricating oil taken from and returned to the crankcase of an automotive engine or the like.
  • the general object of the present invention to provide an improved heat exchanger which avoids the aforestated disadvantages and which is particularly, though not exclusively, useful in conjunction with viscous fluids of low heat-transfer coeflicient.
  • a heat exchanger whose elongated, preferably cylindrical housing, forming a channel for a first fluid, contains a thermally conductive structure including a plurality of coaxial helicoidal elements of alternating direction of pitch, this structure being constituted at least in part by a conduit or conduits carrying a second fluid in heat-exchanging relationship with the first fluid;
  • the helicoidal elements which may be fluid-carrying pipes and/or ribs mounted on the outer surfaces of such pipes, subdivide the elongated channels into a plurality of intercommunicating helicoidal zones which deflect the first fluid from its linear path and force it to move with both radial and tangential velocity components so that turbulence is imparted to this fluid and the deposition of a sluggish boundary layer is substantially prevented.
  • helicoidal is used in this context to describe coiled configurations of a generally helical nature wherein the spacing and other dimensions of successive turns are not critical and need not be uniform.
  • FIG. 1 is a longitudinal sectional view of a heat eX- changer according to a first embodiment
  • FIG. 2 is a fragmentary view of a second embodiment, shown partly in axial section and partly in elevation;
  • FIG. 3 is a partly sectional and partly elevational view of a third embodiment.
  • FIG. 4 is a fragmentary view of a modification of the structure shown in FIG. 2.
  • A designates a first fluid, which may be a relatively viscous liquid such as oil
  • B identifies a second fluid which may be a more mobile liquid or gas.
  • FIG. 1 there is shown a heat exchanger whose housing 1 has a cylindrical peripheral wall with frustoconical ends terminating in a pair of axially aligned ports 1a, 1a for the admission and discharge of the fluid A.
  • Core 2 is surrounded by an inner tier of helicoidally interleaved pipes 3 of good thermal conductivity which are spaced apart to define a multithread helicoidal path around the core; these pipes 3, in turn, are encased within a second tier of similar pipes 4 which are coiled in the opposite direction but have substantially the same spacing and pitch angle as the former.
  • the multithread helicoidal path defined by the pipes 4 communicates at numerous locations with the flow path formed by the pipes 3 so that the fluid stream A will distribute itself throughout the housing and will be turbulently deflected in three dimensions before exiting from outlet port 1a.
  • a second fluid B may traverse all the interleaved and nested pipes 3, 4 in series or in parallel; as shown in FIG. 1, fluid enters one of the inner conduits 3 and leaves one of the outer conduits 4 in the vicinity of port 1a so that part of this fluid flows countercurrent to fluid A.
  • FIG. 2 there is shown a modified housing whose cylindrical peripheral wall 21 is formed at opposite ends with lateral inlet and outlet ports 21b (only one shown) for the fluid stream A; a conical transverse partition 6 at each end of cylindrical wall 21 has apertures 21a leading to respective helicoidal pipes 3', 3", 4 and 4" which surround a straight central tube v5 and are disposed in four nested tiers of alternate pitch direction.
  • Fluid B introduced into port 7a, enters the confronting open end of tube 5 as well as the apertures 21a leading to the pipes 3', 3", 4' and 4", traversing all these conduits in its passage toward the exit port at the opposite end of the housing.
  • the thermally conductive structure constituted by these conduits again serves to deflect the fluid A, moving in counterflow to fluid B, in a swirling flow onto a path of many helicoidal and radial branches.
  • FIG. 3 comprises a housing 31, generally similar to housing 1 of FIG. 1, whose frustoconical end walls are penetrated by inlet and outlet ducts 8, 8 for the fluid A that open into an inner space defined by a generally cylindrical partition 9 which parallels the wall of housing 31 and forms therewith an annular channel 32 for the passage of fluid B; the latter is admitted into this channel by way of a lateral inlet port 31b, and, in flowing toward a lateral exit port 3111' at the opposite housing end, partly traverses a pipe 10 which extends for the most part axially within housing 31 as a bypass to channel 32.
  • the outer periphery of pipe 10 and the inner periphery of partition 9 carry respective helicoidal ribs 11, 12 of opposite pitch direction which again divide the space occupied by fluid A into a plurality of nested helicoidal zones.
  • the entire integral structure 9-12 is made of a highly heat-conductive metal, e.g. copper or stainless steel, to facilitate heat exchange between the two fluids.
  • helicoidal fins or ribs on a conduit for fluid B designed to deflect the external fluid A as illustrated in FIG. 4 a modification of the system of FIG. 2 wherein a central tube 45, provided with helicoidal ribs 45a, replaces the plain tube 5 surrounded by the inner tier of helicoidal pipes 3.
  • these helicoidal pipes could also be provided, in whole or in part, with such external helicoidal ribs.
  • a heat exchanger according to this invention may be directly connected, by its axial ports such as those shown at 1a, 1a, or 8, 8', in a pipeline carrying one of the fluids to be heated or cooled.
  • the volume of such heat exchangers is only about a third or a fourth of that of conventional devices of comparable heat-exchanging capacity and that the rate of flow for the control fluid B is similarly reduced.
  • a system of the type as shown in FIG. 2, with separate cylindrical and frustoconical housing sections 21 and 7, may be extended at will by the insertion of addional cylindrical sections through which the fluid B passes in succession; fluid A may be led into the several housing sections by suitable external connections between their respective side ports 21b.
  • Such a system may also be used, for example, as a water heater of considerably greater compactness than conventional boilers, with the water (fluid B) entering and leaving axially via ports 7a and manifolds 6 while the hot combustion gases (fluid A) from a fire chamber are introduced and withdrawn laterally via ports 21b.
  • FIGS. 1 and 3 may be utilized in analogous manner for similar purposes.
  • Fluid A for example, may be a gas to be fractionated by selective condensation of some higherboiling constituent thereof.
  • a heat exchanger comprising an elongated housing forming a channel for a first fluid, first inlet and outlet means on said housing communicating with said channel, thermally conductive conduit means traversing said housing in a generally longitudinal direction and forming a path for a second fluid in heat-exchanging relationship with said first fluid, and second inlet and outlet means on said housing at the ends of said path, said conduit means forming part of a thermally conductive structure including a plurality of alternately crossing coaxial helicoidal tubes in turns of opposite senses which extend within said channel between said second inlet and outlet and subdivide said channel into a plurality of intercommunicating baflies whereby turbulence is imparted to said first fluid, said coaxial helicoidal tubes forming a packing substantially filling said channel and forming narrow interstices therebetween for the passage of said first fluid.
