Definitions

  • this same device also serves for the cooling of the vanes in the hot fluid zone, presenting a clear option of its use as a cooler for materials located in hot flow zones, thus prolonging the useful life of these materials, as well as its replacement by others of inferior characteristics, lowering costs.
  • SUBSTITUTE SHEET (RULE 26) Likewise, given its rotating nature and the amount of energy that in the form of pressure and kinetic energy usually bring the fluids to be heated - cooled, with a suitable design of the blades as a turbine, power can be extracted from the device through a axis.
  • the fluids to be cooled and heated have to be led to the exchanger in concentric ducts, with the cooling fluid occupying the interior area and the fluid to be cooled outside.
  • the refrigerant fluid and the refrigerated fluid can go in the same direction or in the opposite direction, the opposite direction being more effective in order to take full advantage of the favorable exchange in the concentric conduction.
  • both fluids pass through the blades without mixing, since there is a sealing system between both fluids, and they are driven again concentrically and already refrigerated / heated to the areas where they wish to apply.
  • the concentric conductions are only necessary to the entrance and exit of the changer, being able immediately afterwards to adopt any configuration.
  • Cooling is carried out on the pallets in the following manner.
  • the blades are hollow and inside there is a liquid that is capable of changing phase between the temperatures of the refrigerant and the refrigerated (eg the temperature of the refrigerant is liquid and that of the refrigerated is gas) .
  • This cycle is continuous, as long as the vanes are rotating around a concentric axis with the coolant and hot fluid pipe.
  • the exterior and interior walls of the vanes will be designed in such a way that the convection coefficient is improved as much as possible, with the use of fins, corrugated sheets, ribs, turbulators or any other mechanism.
  • the spinning effect of the paddles can be achieved by using a motor to turn them, or, if a greater energy use is still desired, with the energy that the fluids bring to cooling / heating as a turbine designing the blades of appropriate form. See a design scheme of blades propelled by the fluid in figure 3
  • the same device also serves for cooling the material of the vanes immersed in the hot fluid, since having inside a circulation of a gas-liquid mixture of lower temperature at all times to that of the hot fluid that surrounds it will keep the material at a temperature significantly lower than that of the fluid.
  • the design in its changer version is suitable for any industrial field that requires an efficient heat exchange.
  • Examples of immediate application are gas and steam turbines for cooling between stages, stages or secondary bleedings and for preheating of heavy fuels.
  • gas and steam turbines for cooling between stages, stages or secondary bleedings and for preheating of heavy fuels.
  • petrochemical and industrial plants in general for heating and cooling in the various phases of the process.
  • land and marine vehicles for engine cooling, in aircraft for engine cooling and passenger air heating.
  • air conditioning systems to minimize the size of these and realize a better energy use of the process, etc ...
  • the design in its refrigerator version of materials is immediately applicable in any type of turbo machinery that manages gases at elevated temperatures in order to cool the rotating components immersed in the hot fluid stream.
  • Figure 4 shows the refrigerant fluid and the refrigerated circulating in the same direction for reasons of representative simplicity, there being no impediment to circulate the fluids in the opposite direction taking advantage of the effects already discussed.
  • the surfaces are represented as smooth although, as already mentioned, to improve their efficiency they can be equipped with fins, etc.
  • SUBSTITUTE SHEET (RULE 26) The relationship between Ll, L2, L3, DI, D2 and D3 will be given by the physical characteristics of the fluids involved, as well as the thicknesses, the mechanical characteristics required and the shape of the blades. The number of stages (discs) of pallets that will have to be used will also depend on the specific circumstances of each case.
  • Figure 6 is a front view that in the case of the figure is the entry of both fluids the refrigerant and the refrigerated.
  • Figure 7 is a representation with the transparent blades to show the complete arrangement of the concentric ducts.

Abstract

L'invention concerne un ensemble échangeur thermique-réfrigérateur qui utilise la capacité de changement de phase du fluide d'échange intermédiaire entre les températures de la partie chaude et de la partie froide ainsi que la force centrifuge produite par la rotation afin de remplir sa fonction de façon continue et efficace. Le dispositif agit aussi bien comme un échangeur thermique entre un fluide froid et un fluide chaud que comme réfrigérateur de n'importe quel élément creux qui se trouve immergé dans une zone chaude et dans une zone froide, qui est en train de tourner et qui peut être rempli avec un fluide capable de changer de phase entre les températures des zonas chaude et froide.
