Definitions

  • the present invention relates to an electromagnetic induction electric heater for fluids.
  • Electric heaters for electromagnetic induction fluids are a category of electric heaters for fluids that use the heat produced by Joule effect by parasitic currents induced in a conductive material by an electromagnetic field generated by one or more coils in which a variable current flows.
  • variable magnetic field is induced by the oscillating currents that travel the coils; the currents are produced by generators not shown in the accompanying figures, and whose description is not relevant for the purposes of the invention.
  • the electromagnetic induction heaters the heat is not produced in the conductor that generates the electromagnetic field but in a material in direct contact with the fluid to be heated.
  • US 6118111 overcomes some limitations of the previous solution.
  • the tube bundle is replaced by an assembly consisting of two concentric tubes of non-conductive material which delimit an annular chamber inside which a cylindrical corrugated element of a conductive material is housed, the function of which is to realize the single turn coil of the secondary circuit where heat is generated.
  • the limitation of this solution is linked to the small exchange surface between the fluid and the heating element, consisting solely of the inner and outer surface of the corrugated cylindrical element. To increase the exchange surface it is necessary to increase the diameter of the heating element and consequently also the dimensions of the magnetic circuit in which the assembly is contained.
  • WO 89/12204 discloses a solution that improves the ratio between the size of the heating unit and the heat exchange surface.
  • the coil of the secondary circuit, with the function of heating element consists of a spiral crossed by the fluid from the external turn towards the internal part (or vice versa), therefore in this solution the exchange surface is increased with the same volume occupied.
  • the exchange surface is increased with the same volume occupied.
  • EP0873045A1 describes a heater consisting of a tube of non-conductive material surrounded by a cylindrical coil adapted to generate a field within the heater's tube.
  • the heating element consists of a matrix of interconnected plates in such a way as to form an element capable of being crossed by parasitic electric currents and at the same time to realize a structure capable of having a high exchange surface per unit of volume and to generate a mixing and a turbulent motion of the fluid passing through it.
  • WO2012/150530 discloses an electromagnetic induction fluid heater according to the features of the preamble portion of claim 1.
  • the object of the invention is to eliminate the drawbacks and problems of the different solutions of the prior art illustrated above.
  • an object of the invention is to provide an electromagnetic induction heater which allows to obtain high specific powers without geometric limitations.
  • Another object of the invention is to provide such a heater for electromagnetic induction fluids in which there is a high heat exchange surface per unit of volume.
  • Another object of the invention is to provide such a heater for electromagnetic induction fluids in which there is high mixing without stagnation points, which can also be used with high viscosity fluids without adopting complex heater geometries.
  • Another object of the invention is to provide such a heater for electromagnetic induction fluids in which the greatest modularity and scalability is obtained.
  • Another and not the last object of the invention is to provide such a heater for electromagnetic induction fluids which is simple to make, therefore economical, and at the same time extremely reliable.
  • the heater for electromagnetic induction fluids comprises:
  • an electromagnetic induction heater according to the invention is shown in section, generally indicated by the reference number (100).
  • the heater (100) substantially consists of a coil 1 crossed by an alternating electric current for generating an electromagnetic field, a hollow cylindrical container 2 made of an electrically non-conductive and non-magnetic material, compatible with the fluid to be heated, and a heating element 3 consisting of a set of balls 4 of conductive material coated with an electrically insulating layer compatible with the fluid to be heated. Said spheres fill the cavity of the container according to an ordered or random packing.
  • the container 2 is arranged inside the coil 1 and is closed at its ends by two flanged flanges 5, of perforated cylindrical shape, provided with hydraulic connections for the fluid inlet and outlet respectively.
  • variable electromagnetic field produced by the induction coil 1 generates in the spheres 4 parasitic currents which due to Joule effect determine the heating of the spheres 4.
  • the fluid to be heated passes through the ball bed of the heating element 3 heating by conduction and convection.
  • the spheres 4 are electrically isolated from each other, the resulting parasitic currents cannot circulate in a continuous electric circuit on the periphery of the heating element 3, therefore the skin effect typical of the electromagnetic induction processes can occur only within the single sphere 4. In this way the shielding effect on the central part of the heating element 3 produced by the currents which, due to the skin effect, circulate on the surface of a continuous matrix heating element is avoided, and consequently a greater uniformity of the power density is obtained. in the whole body of the heating element 3.
  • Figure 2 shows the ball bed heating element 3 which ensures excellent mixing of the fluid even in the case of very viscous fluids without stagnation points.
  • the size of the balls 4 can be optimized according to the specific flow rate and the viscosity of the fluid that passes through the heating element 3 and the dimensions of the container 2.
  • balls of increasing diameter are used as viscosity and/or flow rate increase(s).
  • the ball bed heating element 3 comprises a simple constructive solution that can be scaled over a wide range of powers that does not require the construction of complex geometry elements.
  • Figure 3 shows in cross section one of the spheres which constitute the heating element 3.
  • the electrically insulating outer layer 4 ' covers the internal part in conductive material 4' '.
  • the conductive material 4 " of the core of the spheres 4 may have diamagnetic, paramagnetic or ferromagnetic characteristics.
  • the 4 " core of the balls 4 can be full or hollow.
  • the electrically insulating coating of the balls 4 can consist of thermoplastic or thermosetting resin in the case of heaters with operating temperatures up to 200 ° C; for higher temperatures the coating may be of the ceramic type.
  • the choice of electrically insulating coating must be made according to the maximum operating temperature and to the chemical compatibility with the fluid to be heated.
  • Figure 4 shows in section an alternative constructive solution of the heater (100) in which the internal configuration of the flanges 5 is funnel-shaped to prevent the formation of stagnation of the fluid that travels the electromagnetic induction heater from top to bottom with reference to the figure.
  • This solution is particularly suitable for high viscosity fluids, pastes and creams.
