Definitions

  • this device is also possible in the cooling of blades in the hot gas path areas, showing a clear application as cooler of materials located in hot gas areas, increasing this way the useful life of this components, as well as their substitution by others of lower heat resistant characteristics reducing costs.
  • both fluids are conducted to the hollow rotating blades that are the heat exchange pieces, both fluids get across the blades without mixing, because there is a sealing system between both fluids, and at the exit of the blades the fluids are conducted using the concentrical scheme to the areas where they are required.
  • Concentrical conduction are only required at the inlet and outlet of the heat exchanger, being any other disposition possible before or after the exchanger.
  • Refrigeration takes place in the hollow blades as follows.
  • a liquid that is able to have a phase change to gas between the temperatures of the cooling and cooled fluids (i.e. at cooling fluid temperature the inner fluid of the blades is liquid and at the cooled fluid temperature is gas).
  • the fluid inside the blades gasified in the external area of the blade is rotating as well as the blade, and as long as the fluid located in the inner area of the blade is still liquid it will push down the gas to the inner part of the blade (this happens due to the rotation force on the liquid part of the fluid that is more dense that the gas phase and it is pushed to the external area of the blade), in this area the gas will be liquefied again because of the temperature of the external fluid circulating into the inner pipe that will be heated by the heat exchange phase of the inner blade fluid.
  • This working cycle is continuos , providing the centre of rotation of the blades is coincident with the centre of both concentrical conductions.
  • FIG. 2 shows an scheme of the described process.
  • External and internal walls of the blades will be designed in a way that increases as much as possible the HTC, using ribs, turbulators, or whaterever improved design.
  • the rotation of the blades can be achieved using an external motor or, in order to get a better efficiency, using the energy available in the fluids to cool - heat designing the blades in an adequate mode. It can be seen a scheme of design of the blades powered by fluids in figure 3.
  • the transition of the fluids from the static zone (concentrical pipes) to the rotating one (blades) will be designed using adequate sealing systems depending on the fluids (i.e. labyrinth seals, gas seals, mechanical seals..).
  • the same device is also useful to cool down the material of the blades located in the hot fluid path, because as long as in the inner hollow are is all the time circulating a mixture of the inner gas liquid fluid, the temperature of this mixing is always lower than the one of the fluid located in the external area of the blade, so the blade material temperature is sensibly reduced.
  • the design in its heat exchanger version is applicable to whatever industrial field requiring an efficient heat exchange. Clear immediate application examples can be found in gas or steam turbines for the cooling of different stages, secondary airflow preconditioning or preheating of heavy fuels. In petrochemical or industrial plants to heat or cool several process fluids. In terrestrial vehicles, ships or planes to cool down engines and heating the air-conditioned for passengers. In air conditioning systems to reduce their size and achieve better efficiencies, ...
  • the design in its material cooling version it can be applied immediately in all type of turbo machinery that deals with hot fluids to refrigerate turbo machinery components located in the hot fluid path.
  • Figure 4 shows cooling and cooling fluids circulating in the same direction to simplify the figure, not existing in the design any obstacle to make both fluids to circulate in different directions as we have told before.
  • Figure 6 shows a front view showing inlet of both fluids to the device.
  • Figure 7 shows the blades transparent to allow the viewing of the concentrical disposition of the concentrical conducts.
