Definitions

  • the invention relates to an existing of polymer hollow fibers exchanger which determines heat exchange between two flowing media and in particular for transport, air conditioning, food industry, chemical industry, heat recovery and the like. is determined.
  • Heat exchanger, radiator, radiator and the like are often used as design elements in various installations where heat is transferred between flowing media - liquid gases, gases, multiphase mixtures or solid particles.
  • the heat exchangers ensure e.g. Cooling and conditioning in means of transport.
  • the coolers used in means of transport consist predominantly of a pair of collecting tanks connected by a heat exchange zone consisting of many narrow passages. A heat exchange zone is concentrated in them in a relatively small space. It is usually formed by differently shaped tubes with ribs. These are assembled so that they form a compact construction group, where a heat transfer medium flow inside the pipes and another heat transfer medium outside the pipes.
  • Collecting boxes of the exchangers intended for transport are usually made of plastic and their aluminum heat exchange zone.
  • the flow of air as the cooling medium is triggered either by the movement of the vehicle or by a cooling fan, which ensures the flow at standstill of the vehicle.
  • a disadvantage of the common coolers are the production costs and their relatively large mass and total volume. As a location of the cooler only the front of the vehicle or an air duct formed for this purpose come into question.
  • heat exchangers whose heat exchange surface is formed by polymer hollow fibers. They are used in particular in medical apparatus, where they mediate except heat exchange and mass transfer between two media. A typical use is hemodialysis or blood oxidation. The hollow fibers are most often passed in parallel with the medium flowing around the outer side of the fibers either flowing parallel to the fibers, or perpendicular to them.
  • Such exchangers are eg in the US 4791054 described.
  • fibers in the cylindrical heat exchanger after EP 1671695 are guided in parallel, but curled regularly sinusoidal.
  • a spatial arrangement of the fibers in an exchanger is in the EP 2708279 designed.
  • the fibers are here positioned in the direction of three mutually perpendicular axes.
  • the structure of the heat exchange zone in the above-mentioned hollow fiber exchangers is predetermined by the type and location of the exchanger.
  • the object of the invention is to provide a heat exchanger at low production costs and low weight and with a substantially increased ratio of the exchange surface to the volume of the exchanger, an intense heat exchange, variable arrangement in variously shaped spaces and easy manipulation during assembly and maintenance guaranteed.
  • an exchanger made of polymer hollow fibers, which determines heat exchange between two flowing media, whose heat exchange surface in the heat exchange zone at least one bundle of curved, lump-forming hollow fibers is formed, the fibers being embedded together at each end of the bundle, eg forming flanges.
  • the term "lump” is to be understood as meaning a structure formed by fibers which take place randomly and continuously in different, even opposite directions and are arranged arbitrarily in space.
  • the heat exchange surface thus represents an elastic and deformable body.
  • the fiber bundles may be attached at least at one end to a collecting box of the exchanger.
  • the heat exchange zone may be delimited by a frame housed in a stream flowing around the fibers.
  • the exchanger may e.g. attached to a means of transport and exposed to the draft, which flows around the means of transport, or flows through.
  • the heat exchange zone may fill a cavity connected to the ambient medium at locations between which there is a pressure drop which ensures the flow of the medium through the heat exchange zone.
  • the heat exchange zone may e.g. be spatially defined by a design-related cave in a wheel frame or car body of a transport.
  • the flanged ends of the fiber bundles may be attached to any structural part of a plant, e.g. on the structure of an air conditioner.
  • a heat exchanger according to the invention designed as a motor vehicle radiator, which is schematically shown in FIG Fig. 1 is shown, is formed by a pair of manifolds 1 with pipe socket 2 and a heat exchange zone, which is composed here of three hollow fiber bundles 3, the flanges 4 open into the manifolds 1.
  • the bundles 3 are formed by hollow fibers of the same length, which are curved and form a lump.
  • the lump substantially fills the space within the radiator frame.
  • nets or grids would be attached to the outside of the frame, holding the lump together in the particular space.
  • a mere, a lump-forming and flanged hollow fiber bundle is for the sake of clarity in Fig. 4 shown.
  • the warmed up in the internal combustion engine of a vehicle fluid flows into one of the headers 1, from there through the hollow fibers, where they by means of flowing air is cooled, and then it is led away from the other collection box 1.
  • the heat exchanger after Fig. 1 Can be used as a viable car radiator, which is usually mounted in front of the engine block.
  • the embedded in a pipe heat exchanger after Fig. 2 can be used advantageously in the heat transfer between two liquids.
  • Construction-related cavities are part of the motor vehicle construction.
  • Design-related cavities 5 in a car body of a common car are in Fig. 4 shown schematically.
  • Fig. 1 is also the course of the air pressure shown, which acts during the vehicle movement on the flow around the car body.
  • the pressure acting on the top of the car body in places where the cavities open assumes the values P 1 , P 2 , P 3 , P 4 , while the pressure acting on the underside of the car body assumes the values P ' 1 , P' 2 , P ' 3 , P' 4 assumes.
  • Fig. 3 it represents a heat exchange zone according to the invention.
  • a heat exchanger was prepared whose tube mounted heat exchange zone was formed by four hollow fiber bundles.
