Title
(EN) METHOD FOR CONTROLLING THE TEMPERATURE OF A FLEXIBLE CELLULAR MATERIAL BY COMPRESSION / EXPANSION OF THE GAS TRAPPED IN ITS CELLS AND ASSOCIATED DEVICE
(FR) PROCEDE DE THERMOREGULATION D'UN MATERIAU SOUPLE ALVEOLAIRE PAR COMPRESSION DETENTE DU GAZ EMPRISONNE DANS SES ALVEOLES ET DISPOSITIF ASSOCIE
Abstract
(EN)
The invention concerns a method for controlling the temperature of a flexible material. The flexible material made from silicone or another elastomer is made up of two layers with different shore hardnesses (H) and conductivities (λ) and that are provided with a plurality of specific gas-filled cells. Each cell has two zones connected to each other: one for storing the gas when the material is compressed and that is positioned in the layer having higher hardness and thermal conductivity (layer C) and the other for expanding the same gas, when the material is decompressed, in the layer having lower hardness and thermal conductivity (layer D). The flexible material can thus be used as a sole in shoes in order to maintain a cool temperature when the person is running on hot ground, for example. At each step, the foot compresses the flexible material and the cell zones situated in layer C thus act as adiabatic chambers in which the gas heats up as it is compressed. The higher thermal conductivity of layer C allows better heat exchange to the outside. When the foot leaves the ground and there is therefore no longer any compression, the flexible material regains its volume through the elasticity of the material and the cell zones situated in the layer (D) act as a reactor nozzle that expands the air and therefore cools it. The lower thermal conductivity of this layer allows this coolness to be conserved.

L'invention concerne un procédé pour thermo-réguler un matériau souple. Le matériau souple en silicone ou autre élastomère est constitué de deux couches de duretés shore (H) et de conductibilités (λ) différentes et sont munies d'une multitude d'alvéoles spécifiques remplies de gaz. Chaque alvéole présente deux zones reliées entre elles: l'une pour emmagasiner le gaz lors de la compression du matériau et qui se positionne dans la couche à plus fortes dureté et conductibilité thermique (couche C) et l'autre pour détendre le même gaz, lors de la décompression du matériau, dans la couche à plus faibles dureté et conductibilité thermique (couche D). Le matériau souple peut ainsi être utilisé comme semelle dans les chaussures afin de maintenir une température fraîche lorsque la personne court sur un sol brûlant par exemple. Lors de chaque pas, le pied va compresser le matériau souple et les zones d'alvéoles situées dans la couche C vont donc agir comme des enceintes adiabatiques dont le gaz en se comprimant va s'échauffer. La plus forte conductibilité thermique de la couche C va permettre un meilleur échange de chaleur vers l'extérieur. Lorsque le pied quitte le sol et donc qu'il n'y a plus de compression, le matériau souple va reprendre son volume par le jeu de l'élasticité du matériau et les zones d'alvéoles situées dans la couche (D) vont agir comme une tuyère de réacteur qui va détendre l'air et donc le refroidir. La plus faible conductibilité thermique de cette couche va permettre de conserver cette fraîcheur.
