Definitions

  • the present invention due to the work of Professor Félix TROMBE and gentlemen, Raymond BERGER, Maurice de CACHARD and André GOUZY from the French Atomic Energy Commission, has for its object a modular device for producing cold.
  • Apparatuses for the production of cold operating independently are known according to the prior art, that is to say without external energy supply and having no moving part, which gives them great simplicity and excellent reliability. These devices are based on the known property that the Earth's atmosphere has of preferentially passing the radiation between 8 and 13 1 i and between 16 and 25 ⁇ . Part of the radiation emitted by black bodies is in these ranges.
  • a black body is a body which completely absorbs the radiation it receives, whatever its wavelength. Such a body is in thermodynamic equilibrium with the radiation it receives and with the radiation it emits. In principle, the emissivity of a black body is equal to unity and extends across the spectrum, in particular in the windows of transparency of the atmosphere. When a black body is placed in the atmosphere, the part of energy that it radiates in said windows is transmitted to space almost without accumulation. This results in cooling of the emitter body. The drop in temperature undergone by this body is however limited if parasitic heat exchanges take place with the ambient air or with the ground, either by convection, or by the intermediary of condensation phenomena linked to the degree of humidity of the air.
  • the body which undergoes cooling due to its radiation through the windows. very transparent atmosphere is thermally connected to a material which has a solid-liquid transition in the vicinity of the operating temperature of the device.
  • This thermal connection is effected by means of a heat pipe heat pipe which acts as a thermal diode and which ensures thermal connection only in the direction of the material towards the black body. This results in a lowering of the temperature of the material causing it to solidify without the reverse transformation from the solid phase to the liquid phase being able to occur, since the transfer of the calories which could come from the radiating body is blocked by the thermal diode.
  • the device therefore produces cold and stores it.
  • FIG. 1 An embodiment of such an apparatus for producing cold of known type.
  • This device comprises a radiating surface 2 thermally connected to a heat pipe 4 constituting a thermal diode.
  • the lower part 6 of this heat pipe is provided with fins 8 which have the purpose of increasing the exchange surface between the fusible material and the heat pipe 4, and is immersed inside a fusible material which is liquid at the daytime ambient temperature, of water for example, this tank being thermally insulated from the ground and sealed by its walls, for example made of plastic.
  • This storage tank has not been shown in FIG. 1.
  • the heat pipe 4 has a discontinuous capillary structure, which makes it possible to perform the function of thermal diode: when the radiating surface is at a temperature higher than that of the storage enclosure, the condensed liquid of the heat pipe remains in the lower part of the heat pipe and the transfer of calories by the heat pipe cannot be carried out.
  • the heat pipe is filled with a compound whose evaporation point is compatible with the operating temperature of the device: for example, a freon or ammonia.
  • the fins work in thermal conduction regime. As a result, their yield is not very high. Thus, the thermal bond between the storage material and the heat pipe 4 is relatively 'poor.
  • the radiating surface 2 also works in thermal conduction regime. As a result, the thermal bond between this radiating surface and the heat pipe is also relatively poor.
  • the present invention specifically relates to an apparatus for producing cold which overcomes the drawbacks of previously known devices. It simplifies the production thereof, appreciably increases its thermal efficiency, and above all it reduces its size during transport, which makes it possible to obtain a significant reduction in the costs of manufacture, transport and installation.
  • connections between the serpentine-shaped conduits formed on each of the panels, one for the flow of steam to the condenser, the other for the return of the liquid to the evaporator are made of annealed metal, copper or aluminum for example. This makes it possible to fold and deploy the assembly a certain number of times without risk of leaks or ruptures.
  • the assembly constituted by the radiating surface, the second evaporator panel, the closed circuit is formed by a single perforated panel in its central part to determine an upper panel forming the radiating surface and a lower panel forming an evaporator.
  • FIG. 2 shows a first embodiment of the cold production apparatus according to the invention.
  • This device consists of a first panel 10 forming a radiating surface whose radiation falls into at least one window of transparency of the atmosphere, a second panel 12 immersed substantially vertically in the material of the storage enclosure.
  • a coil-shaped conduit 14 is formed on the panel 10.
  • a conduit 16 substantially identical to the conduit 14 is formed on the panel 12.
  • the end 14a of the conduit 14 is connected to the end 16a of the conduit 16 by a connector 18
  • the end 14b of the conduit 14 is connected to the end 16b of the conduit 16 by a connector 20.
  • the connector 20 comprises a filling nozzle 22 by which a certain amount of a heat transfer fluid is introduced.
  • This heat transfer fluid by example a freon or ammonia is vaporizable under the operating conditions of the device.
  • the tube 18 is used for the departure of the steam to the condenser, while the tube 20 is used for the return of the heat transfer liquid to the evaporator.
  • the thermal bond between the storage material and the evaporator panel 12 is improved due to the presence of the duct 16 in the form of a serpentine over the entire surface of the evaporator.
  • the thermal connection between the duct 14 and the condenser panel is improved.
  • the apparatus can be produced according to the "Roll Bond” process which consists in depositing by printing (rotary type for newspapers) a paint on a metal sheet; another metal sheet is then placed and the whole is hot-rolled. Diffusion molding occurs except in areas covered with paint. A pressure is then created which detaches the non-welded parts.
  • the . panels 10 and 12 can be formed by condenser panels commonly used in the refrigeration industry. Therefore, the cost of the device is decreased. The space requirement during transport is also reduced, which allows a reduction in the cost of this transport.
  • connections 18 and 20 are made of a plastically deformable material, for example copper or annealed aluminum, which makes it possible to fold and deploy the assembly a certain number of times without risk of leaks or ruptures.
  • the structure thus obtained is called “portfolio” as opposed to the structure of the device according to the prior art described above, called “open umbrella”. The space requirement during transport is thus reduced.
  • FIG 3 An alternative embodiment of the device shown in Figure 2.
  • This device is made in a single panel which simultaneously fulfills the functions of condenser in its upper part 10, and evaporator in its lower part 12.
  • the zones 10 and 12 are separated by openings 24 which make it possible to thermally isolate the evaporator 12 from the condenser 10.
  • the connections 18 and 20 of the previous embodiment are thus eliminated, the closed circuit inside which finds the heat transfer fluid being produced in a single game. Only the filling nozzle 22 remains necessary for the heat transfer fluid.
  • This panel can also be produced using the "Roll Bond” process.
  • This simple and inexpensive device can be used on very large surfaces, and it is interesting to present it in modular form. Such an embodiment is shown in FIG. 4.
  • the panel formed in one piece described with reference to Figure 3 is hung by a flange 26 obtained by folding the end of the panel 10 to a float 28.
  • the shape of the float 28 which can be produced by example in expanded polystyrene, is determined so as to match that of the panel and to give the whole the desired base according to the geographic and topographical data of the location.
  • Modular devices such as that which is represented in FIG. 4, all identical but completely independent of each other can be juxtaposed to completely cover an area as large as desired.
  • the radiant surface can be obtained directly at low cost by an oxidation treatment anode performed after filling with heat transfer fluid and sealing the panel.
