Definitions

  • the invention relates to a plastic plate heat exchanger which comprises a plate stack covered with a front plate and a back plate and sealingly interconnected at the edge, profiled heat transfer plates to form alternately provided for a first fluid and a second fluid flow channels, wherein the heat transfer plates through holes for connection having provided for the respective same fluid flow channels.
  • Heat exchangers made of plastic are characterized by high corrosion resistance, simple and inexpensive production and low weight, but have due to the material used and because of the thickness to achieve sufficient strength greater thermal conductivity or due to the low strength only with low pressures operate.
  • the Indian DE 20 2010 007 615 U1 plastic plate heat exchanger described comprises stacked, manufactured by injection molding heat transfer plates with through holes and a front and a back plate with connecting pipes.
  • the heat transfer plates have on the front and on the back in each case a differently or mirror-symmetrically designed, designed as a flat depression with flow barriers flow channel.
  • the one at the flat edges of a low strength having Heat transfer plates welded or glued plate heat exchangers can only be operated at low pressures.
  • the heat transfer due to the required large thickness of the existing plastic heat transfer plates is comparatively low.
  • plastic heat exchangers are in the US 7004237 B2 , of the EP 0203213 A1 , of the WO 2009 123519 A1 and the EP 2306133 A1 described.
  • the invention has for its object to provide a plate heat exchanger made of plastic, which can be easily and inexpensively manufactured and ensures high pressure resistance and high thermal conductivity.
  • the object is achieved with a trained according to the features of claim 1 plate heat exchanger.
  • the basic idea of the invention is the incorporation of continuous carbon fibers in the heat transfer plates made of plastic, so that on the one hand heat transfer plates with high thermal conductivity are available on the one hand due to the thinness achieved thereby and, on the other hand, the thermal conductivity of the continuous carbon fibers.
  • the identically formed heat transfer plates are with in only one direction oblique to the longitudinal axis extending - an upper and a lower plate level defining - wave crests and troughs as well as a peripheral edge of the plate joint and from this to the plate interior out subsequent circumferential - in relation to the plane of the plate - horizontal connecting region each stacked about a transverse axis plate stacked and fixed to the abutting connecting beads and horizontal connecting portions and at the contact surfaces of crossing peaks and valleys and the abutting high - forming the upper plate level - edge portions of the through holes fixed and sealingly welded or glued together.
  • the simple design and inexpensive manufactured plate heat exchanger is characterized by a high pressure resistance and high heat transfer performance.
  • the heat transfer plates are electrically conductive due to the embedded in the plastic continuous carbon fibers, so that individual heat transfer plates for additional heating of the fluid can be heated by applying a voltage.
  • the connecting beads and the wave crests have a trapezoidal cross-section to achieve a large-area sealing or connecting region between adjacent heat transfer plates.
  • a further embodiment of the invention is at the fluid inlet and outlet of existing between adjacent heat transfer plates flow channel in a low-lying - the lower plate level forming - edge region of opposite through holes arranged the two edge areas mutually supporting and firmly connecting fluid distribution element.
  • the fluid distribution element is designed as a support ring or tie rods and has nozzle-shaped passages for uniform fluid distribution.
  • the wave crests and the troughs for generating a different volume of fluid in adjacent flow channels are formed differently wide.
  • the plate stack covered with the front plate and the back plate is wound in the longitudinal and / or transverse direction with a bandage of fiber-impregnated fibers to further increase the compressive rigidity of the plate heat exchanger.
  • the front and the back plate are convexly curved on the outside in this embodiment. On the outer surfaces of the front and the back plate may also be formed stiffening ribs.
  • a Cyprusisoliermaterial is applied to the outer surface of the plate heat exchanger.
  • the plastic matrix is partially admixed with carbon nanotubes (CNTs) or graphene.
  • the heat transfer plates made of a thermoplastic material and are joined together by friction welding.
  • the connection is made by gluing.
  • the plate heat exchanger 1 in the present exemplary embodiment comprises seven identical heat transfer plates 2, a front plate 3, a back plate 4 and four connecting pieces 5 adjoining openings 3 'in the front plate 3 for supplying and discharging a heat-emitting and a heat-absorbing (first and second) fluid.
  • the heat transfer plates 2 are preferably made of a continuous fiber reinforced thermoplastic, wherein to increase the - thermal and electrical - conductivity in the plastic matrix carbon nanotubes (CNT) or graphene (a carbon with two-dimensional structure) can be dispersed.
  • CNT plastic matrix carbon nanotubes
  • graphene a carbon with two-dimensional structure
  • the plastic heat transfer plates 2 are electrically conductive by the integrated carbon fibers, so that individual heat transfer plates 2 can be heated by applying a voltage and thus a targeted additional heating of the fluid is possible. Due to the stiffening with continuous carbon fibers also low plate wall thicknesses are possible, so that the heat transfer can also be improved due to this Tatsche.
  • the front plate 3 and the back plate 4 which are highly loaded to the ambient pressure, can be additionally stiffened by molded ribs (not shown) and are convexly curved on the outer surfaces.
  • a longitudinally extending and a transversely extending bandage 6 made of plastic impregnated continuous carbon fibers, so that the existing plastic heat exchanger can be operated with an even higher pressure. Due to the curvature of the front and the rear plate internal pressure forces of the heat exchanger are converted into longitudinal forces in the outer contour and recorded there by longitudinally highly resilient fiber bands. It is also possible, but not shown in the drawing, to overmold the plate heat exchanger 1 with a heat insulating material.
  • the fiber-reinforced heat transfer plates 2 are wave-shaped in only one direction (here at an angle of 45 ° to the longitudinal direction, any angle between 0 and ⁇ 90 ° is possible.)
  • the wave crests 7 and wave troughs 8 have the shape of a trapezoid and are the same (However, it is also conceivable to form the wave crests and the wave troughs of different sizes so that different volumes can be transported in adjacent flow channels of the plate heat exchanger 1, for example in the case of media having different viscosities.)
  • the heat transfer plates 2 have one in the outer edge region encircling trapezoidal connecting bead 9 and an outwardly adjoining horizontal edge portion 10 and an inwardly adjoining circumferential, horizontal connecting portion 15.
  • the previously described - identically formed - heat transfer plates 2 are - each rotated about the transverse axis by 180 ° - stacked on top of each other and at the contact surfaces between two plates, that is, to the abutting horizontal ridge 14 of the trapezoidal circumferential connecting beads 9 and to the Seams 9 to the interior of the plates towards adjacent circumferential horizontal connecting portions 15, at the emanating from the through holes 11 abutting edge portions 11 "and the intersecting contact surfaces 16 of the trapezoidal wave crests 7 by friction welding firmly and sealingly connected to each other.A further connection between the plates also in the area of the fluid distribution elements 12. In addition to the friction welding, the connection and sealing can also take place by means of other welding methods or-in the case of heat transfer plates made of thermosetting plastic-by gluing.
  • the above-described plate heat exchanger made of plastic is characterized by the structural and material-side design of the thin, highly thermally conductive and high-strength as well as on several surface sections firmly and sealingly interconnected heat transfer plates by a high pressure resistance and heat transfer performance.
  • the compressive strength is increased by the wrapped around the curved front and back plate bandages of plastic-impregnated continuous fibers.
  • the production of the trained in only a single form of heat transfer plates is carried out by a combined process of forming the thermoplastic fiber-reinforced plastic plate and molding of any required reinforcing or functional elements.
  • the production of the plates and the installation of the plate heat exchanger is simple and inexpensive.
