Definitions

  • the present invention relates to a heat exchange device, and in particular an air-fluid heat exchanger, adapted to be installed inside a ventilation duct or exhaust air.
  • the present invention also relates to a method of installing a heat exchange device inside a ventilation duct or exhaust air, and the system thus obtained.
  • the known state of the art includes several heat exchange devices which are used in a large number of industrial applications.
  • the building industry is offering more and more technical solutions to improve the thermal insulation of homes.
  • These achievements often use heat exchangers, or thermal energy storage systems, to limit the energy loss tower by ensuring an air exchange sufficient to ensure hygiene and comfort.
  • heat exchange devices are used to extract the heat contained in a flow of air that it is desired to evacuate to the outside. This is the case for example systems for recovering the residual heat of the combustion gases emitted by a chimney or boiler, or the emissions of heated air from a kitchen, or so on.
  • Thermal exchange devices are also used when it is desired to heat a stream of air, supplying heat thereto. This is the case, for example, heating or drying installations.
  • air-fluid exchange systems that operate by either heating the air in a pipe or cooling it as needed.
  • autonomous energy exchange devices comprising a chamber connected to the air evacuation duct and, inside the duct, a circuit made with tubular duct plates, at the same time. inside which a fluid is circulated in order to cool or reheat the air
  • the document FR2069950 discloses a heat exchanger device comprising a plurality of stamped plates inside a plenum in which a forced circulation of air is established. Similar solutions are also known for example from the documents FR2482266 and GB2095394 . Other, more complex systems also include liquid-vapor phase transformations of the heat-exchange fluid, also allow latent heat exchange.
  • An object of the present invention is to provide a heat exchange device and a method for installing such a device free from the limitations of known devices and methods.
  • Another object of the invention is to provide a compact heat exchange device which can be integrated into existing air circulation lines, as well as the corresponding installation method.
  • a heat exchange device for installation inside a pre-existing air circulation duct comprising: a plurality of copper foils assembled so as to give rise to a plurality of hollow plates each having two copper sheets, the edges of the sheets of each plate being welded so as to leave a gap between the sheets, the plates being interconnected by pipes, so as to achieve a coolant circuit coolant inside the plates.
  • the invention relates to a heat exchanger suitable for installation in a pipe 30 in which air is circulated.
  • the pipe 30 could be a vent pipe, or also a flue gas discharge pipe, or a suction pipe connected to a kitchen hood, or any other pipe, the invention being applicable to any which circulation system in which one wishes to exchange air or gas.
  • the pipe is, in a typical case, a tubular pipe made of sheet steel, or a synthetic polymer, with or without a layer (not shown) of thermal insulation.
  • the exchange device of the invention consists of a stack of hollow plates, each made by juxtaposition of two copper sheets 18a and 18b having a concave face and a convex face.
  • the copper foils 18a and 18b are easily made by stamping and / or stamping, from a copper sheet of suitable thickness, but they can be implemented by any suitable technique.
  • the sheets 18a and 18b are assembled in pairs, the concave faces juxtaposed, and their edges 16 are welded together, so as to leave a gap between them in which can circulate water, or a heat transfer fluid.
  • the pipes 23 connect the plates together, and put the hollow spaces in fluid communication, through openings made beforehand in the sheets 18a and 18b so as to provide a coolant circuit coolant inside the plates.
  • the figure 2 illustrates an example of heat exchange device in section, in which the circuit is visible.
  • the pipes 15 and 25 connect the heat exchange device of the invention to an external circuit, not shown, which may include circulation pumps, a heat storage system, radiators, evaporators, burners, heat pumps, or any other device for transferring heat to and from the heat transfer fluid and, via the device of the invention, to the air or gas flowing in the pipe 35.
  • the pipes 23 and the pipes 15 25 are made of copper and are soldered to the sheets 18a, 18b.
  • the hollow plates are all hydraulically connected in parallel, in the sense that the heat transfer fluid is distributed and passes through the plates at the same time.
  • the hollow plates are parallel to each other, so as to create rectilinear right channels of air circulation.
  • the inventors have found that this arrangement makes it possible to achieve optimal heat exchange while minimizing dynamic losses of air circulation. For this reason, the system of the invention does not require a consequent installation to pulsate the air inside the pipe 35 and lends itself well to systems in which the speed of the air is low, or systems based on natural circulation.
  • Another advantage of the device of the invention is that the dimensions and the number of plates is easily adaptable, and the resulting device is particularly compact.
  • The can be used as 'retrofit' in existing installations, preserving and reusing existing pipes.
  • the device can be inserted through a temporary opening made in a wall of a pipe.
