Definitions

  • ABSTRAC [51] Int. C1, F28F 3/08 A versatile heat exchanger capable of being used in a [58] Fleld of Search 165/ 164-166, modular arrangement An impervious member sepa 165/179, 183, 181, 135; 6 /3 rates fluid flow channels, with metal fins extending therethrough and sealed therein so that there is no [56] References C'ted leakage therethrough.
  • HEAT EXCHANGER BACKGROUND OF THE INVENTION Presently known heat exchangers are always so constructed that a wall made of metal or of another relatively good heat conductor, such as graphite, effects the separation between the two media between which heat is to be exchanged. That separating wall is to conduct heat from the medium that is at higher temperature to the one at lower temperature. Because of the weight and the price, the separating wall is made as thin as possible. Because of the ease in manufacture, this separating wall is usually the wall of a tube.
  • the media between which heat exchange is to be effected are either water, organic liquids, or gases. In all cases they have substantially lower heat conductivity than metals. For that reason, many ways have been proposed and in part executed to increase the surface of the metallic tube wall.
  • the present invention resides in a heat exchanger characterized in that it is constructed from different materials, of which only one needs to have good heat conductivity, for example, from metal and plastic, in such a manner that the poor conductor, e.g., the plastic, forms the separating wall between the heat transfer fluid or medium that is to be cooled and the cooling medium, while the good conductor, e.g., the metal, is made to extend through the said separating wall in the shape of lamellae or strips or the like.
  • One advantage of such an arrangement is the corrosion resistant separation that may be brought about between the fluids circulating within the heat exchanger, since the separating wall may be altogether corrosion resistant, its material having been chosen accordingly without said material having to be a good conductor of heat.
  • the heat conducting e.g., metal components of the device
  • a gradual reduction in efficiency occurs at first which may be detected long before serious failure so that leaks which can cause fatal defects of the device may be prevented in time.
  • FIG. 1 is a sectional view of a representative heat exchanger of the present invention
  • FIG. 3 shows a separating member, on an enlarged scale, with fin elements passing therethrough, from which the separating member of FIG. 2 may be constructed;
  • cover sheets 5 and 6 encase the heat exchanger according to the present invention. Between said cover sheets are the sets of elements 7, 8, 9, 10 which subdivide the space into channels 11, 12, l3, l4 and 15. Elements 7, 8, 9 and 10 embody solid, impervious bulkheads separating the channels, and are preferably constructed of plastic material. Channels 11, 12,
  • I3, 14 and 15 formed thereby are fluid flow channels for conveying fluids in heat exchange relationship.
  • a first fluid may be conveyed in channel 11, a second fluid in channel 12, a first fluid in channel 13, a second fluid in channel 14 and a first fluid in channel 15, with the fluids preferably flowing in countercurrent relationship with the fluid flow shown by the arrows.
  • the fluid channels are connected to appropriate headers and means to cause the fluids to flow in the channels, as a pump, not shown, all of which are conventional.
  • One of the sets of elements 7, 8, 9, 10 is shown in FIG. 2 on an enlarged scale.
  • Bulkhead 16 consists of a material that need not be a good conductor and may be a corrosion-resistant material, preferably plastic, and lamellae -17 are made of a material that is a good conductor of heat, preferably metal.
  • the lamallae may be made of a single metal or of an alloy and they may have an improved surface or a coated surface or.a clad surface.
  • the two portions of the lamellae that extend out of bulkhead 16 are of equal size'. This need not be so in all instances. For example, if gas circulates on one side and a liquid on the other, then the portions of the lamellae on the gas side may be substantially larger, but also thinner than the portions extending into the liquid. Instead of the shape given in FIGS.
  • FIG. 3 shows one specific embodiment of the construction of elements.
  • the bulkhead forming parts 18 and 19 are shown as being identical. As here shown they contain therein clearance holes corresponding to half of the thickness of the corresponding portion of lamellae 20 and 21 etc.
  • the bulkhead components and lamellae may be previously produced, e.g., by pressure molding and stamping, respectively, and assembled into elements of the desired height whereby such assembly may be effected largely automatically.
  • Other embodiments particularly well suited for this type of heat exchanger are based upon the fact the two portions of each lamella extending from bulkhead 16 do not exhibit the same surface on both sides.
  • the lamellae are normally pressed or punched parts or stampings, they may be brought into a shape that differs from a plane surface in the course of the same manufacturing process, for example, they may be corrugated, twisted, embossed, shaped into a profile, or perforated.
  • shapes of lamellae may be used that cannot be derived from a plane surface, such as, for example, small rods, wire, or small tubes which may be squeezed down in the area that is inserted into the bulkhead.
  • a further detail in shaping the lamellae may consist in designing them in such a manner that their insertion or assembly into the bulkhead 16 is thereby facilitated; in addition, tightness or imperviousness and firmness of anchoring within bulkhead 16 may thereby be influenced.
  • the shape of the lamellae may also be used to influence the conditions of flow within the heat exchanger. This may, for example, be accomplished by the use of lamellae that are variously shaped according to the direction of flow.
  • the fins may be shaped to increase heat exchange surface, with separating member 16a having a plurality of corrugated fins 17a extending into a first channel 30 and corrugated fins 17! extending into a second channel 31.
  • fins 17a may extend further into channel 30 than fins 17b extend into channel 31.
  • holes 32 may be provided in the fins in order to further increase the heat exchange surface.
  • FIG. 6 which has continuous fins 172 and l7fto provide lamellar flow.
  • Bulkhead 16 will usually be made of plastic.
  • the polymeric materials of construction excel by virtue of their low weight, their good adaptabilty to the requirements of stability against the media that are to circulate in the heat exchanger and also due to their good workability.
  • blocks as shown in FIG. 2 may be produced by casting or injection molding in a single manufacturing step.
  • parts 18 and 19 may be prefabricated by pressing or injection molding for subsequent assembly with the lamellae.
  • Typical plastics include polyolefins, polyvinyl chloride, polycarbonates and the like.
  • Typical fin materials include preferably copper, aluminum and their alloys. The fins may be coated with lacquers or plastic or clad with other poorly heat conducting but corrosion resistant layers without substantially influencing the heat transfer efficiency of said fins provided that such poorly conducting coatings or layers are thin.
  • a heat exchanger comprising: a first channel for conveying a first heat transfer fluid; a second channel for conveying a second heat transfer fluid; a corrosion resistant solid, impervious member separating said first channel and the first fluid circulating therein from the second channel and the fluid circulating therein, said member being a poor heat conductor; a plurality of heat conductive metal fins extending through said member, with a first portion of said fins only partially extending into said first channel and a second portion of said fins only partially extending into said second channel so that the second fluid circulating in the second channel is in heat exchange relationship with the first fluid circulating in the first channel due to heat being conducted substantially only by said fins, said fins being sealed in said member so that there is no fluid leakage through said member.
  • a heat exchanger according to claim 1 wherein at least a portion of said fins are arranged to cause lamellar flow of the fluid adjacent said fins.
  • a heat exchanger according to claim 1 wherein at least a portion of said fins are arranged to cause turbulent flow of the fluid adjacent said fins.
  • a heat exchanger according to claim 1 including a plurality of said members assembled together to form a complete unit, wherein the fins extending through each of said assembled members do not reach the next adjacent member.
